Checking the Engine Oil and

Filter

The lubrication, rust prevention,

cooling, and cleaning effect of the

engine oil will gradually degrade

during its use. Have the engine oil and

filter be changed by an authorized

HYUNDAI dealer according to the

Oil Life Management System or

the Maintenance Schedule at the

beginning of this chapter.

If the maintenance schedule to

replace engine oil is exceeded,

the engine oil performance may

deteriorate, and the engine condition

may be affected. Therefore, replace

the engine oil according to the

maintenance schedule.

To keep the engine in optimal

condition, use the recommended

engine oil and filter. If the

recommended engine oil and filter are

not used replace it according to the

maintenance schedule under severe

usage conditions.

The engine oil change interval is

set for the purpose of preventing

oil deterioration, and is not related

the amount of oil consumption; so,

check and refill the amount of the oil

regularly.

Information

When the oil pressure is low due to
insufficient engine oil, the Engine
Oil Pressure (

) warning light will

illuminate. In addition, the enhanced
engine protection system, which limits
the engine’s power is activated and the
Malfunction Indicator Lamp (

) will

illuminate when the vehicle is driven in
this state continuously. When the engine
oil pressure is restored, the warning light
and the enhanced engine protection system
will turn off after the engine is restarted.

CAUTION

The engine oil is very hot immediately

after the vehicle has been driven and

can cause burns during replacement.

Replace the engine oil after the engine

oil has cooled down.

WARNING

CALIFORNIA PROPOSITION 65

WARNING
Engine oil contains chemicals known to

the State of California to cause cancer,

birth defects and reproductive harm.
Used engine oil may cause irritation or

cancer of the skin if left in contact with

the skin for prolonged periods of time.
Always protect your skin by washing

your hands thoroughly with soap and

warm water as soon as possible after

handling used oil.

NOTICE

Never add any additives to the engine

oil. Engine oil additives can change the

properties of engine oil and may cause

serious engine failure.

Maintenance

The high-pressure cooling system has a

reservoir filled with year-round antifreeze

coolant. The reservoir is filled at the

factory.
Check the antifreeze protection and

coolant level at least once a year, at

the beginning of the winter season and

before traveling to a colder climate.

Checking the Coolant Level

Engine coolant

ONX4H090004

Inverter coolant

ONX4H090005

Check the condition and connections

of all cooling system hoses and

heater hoses. Replace any swollen or

deteriorated hoses.
The coolant level should be filled

between the MAX and the MIN marks on

the side of the coolant reservoir when

the engine is cool.

Engine coolant/Inverter coolant for HEV

- If the coolant level is low, add the

selected anti-freeze according to

the proper coolant mix ratio to bring

the level to the MAX mark, but do

not overfill.

Inverter coolant for PHEV

- If the inverter coolant level for the

PHEV is low, it should be refilled

by an authorized HYUNDAI dealer/

service partner.

system. When you are sure all the

pressure has been released, press down

on the cap, using a thick towel, and

continue turning to remove it.

Information

The engine coolant and/or inverter coolant
level is influenced by the hybrid system
temperature. Before checking or refilling
the engine coolant and/or inverter coolant,
turn the hybrid vehicle off.

WARNING

The electric motor for the cooling fan

may continue to operate or start up

when the engine is not running and

can cause serious injury. Keep hands,

clothing and tools away from the

rotating fan blades of the cooling fan.
Always turn off the vehicle unless the

vehicle has to be inspected with the

engine on. Be cautious as the cooling

fan may operate until you disconnect

the (-) battery terminal (For plug-in

hybrid vehicle) or the battery connector

(For hybrid vehicle).

WARNING

Make sure the coolant cap is properly

closed after refilling coolant. Otherwise

the engine could be overheated while

driving.

Recommended coolant

When adding coolant, use only

deionized water, distilled water or soft

water for your vehicle and never mix

hard water in the coolant filled at the

factory.

An incorrect coolant mixture can

result in severe malfunction or

engine/hybrid system damage.

The engine in your vehicle has

aluminum engine parts and must be

protected by an phosphate-based

ethylene glycol coolant to prevent

corrosion and freezing.

Do not use alcohol or methanol

coolant or mix them with the specified

coolant.

Do not use a solution that contains

more than 60% antifreeze or less than

35% antifreeze, which would reduce

the effectiveness of the solution.

For mixing percentage, refer to the

following table:

Ambient

Temperature

Mixture Percentage

(volume)

Antifreeze

Water

5°F (-15°C)

-13°F (-25°C)

-31°F (-35°C)

-49°F (-45°C)

Information

If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of -31°F
(-35°C) and higher.

Changing Coolant

Have coolant changed by an authorized

HYUNDAI dealer according to the

Maintenance Schedule at the beginning

of this chapter.

WARNING

Do not use engine coolant or antifreeze

in the washer fluid reservoir.
Engine coolant can severely obscure

visibility when sprayed on the

windshield and may cause loss of

vehicle control resulting in an accident.
Engine coolant may also cause damage

to paint and body trim.

NOTICE

To prevent damage to engine parts, put

a thick towel around the engine coolant

cap and/or inverter coolant cap before

refilling the coolant to prevent the

coolant from overflowing into engine

parts, such as the alternator.

periodically. The fluid level should be

between MAX and MIN marks on the side

of the reservoir.
Before removing the reservoir cap and

adding brake fluid, clean the area around

the reservoir cap thoroughly to prevent

brake fluid contamination.
If the level is low, add the specified brake

fluid to the MAX level. The level will fall

with accumulated mileage. This is a

normal condition associated with the

wear of the brake linings. If the fluid level

is excessively low, have the brake system

checked by an authorized HYUNDAI

dealer.

WARNING

If the brake system requires frequent

additions of fluid this could indicate

a leak in the brake system. Have the

Check the fluid level in the washer fluid

reservoir and add fluid if necessary.

Plain water may be used during summer

months if washer fluid is not available.

However, use washer solvent with

antifreeze characteristics in cold climates

to prevent freezing.

WARNING

To prevent serious injury or death, take

the following safety precautions when

using washer fluid:

Do not use engine coolant or

antifreeze in the washer fluid

reservoir. Engine coolant can

severely obscure visibility when

sprayed on the windshield and

may cause loss of vehicle control

resulting in an accident or damage to

paint and body trim.

Do not allow sparks or flame to

contact the washer fluid or the

washer fluid reservoir. Washer fluid

may contain alcohol and can be

flammable.

Do not drink washer fluid and avoid

contact with skin. Washer fluid is

harmful to humans and animals.

Keep washer fluid away from

children and animals.

WARNING

Do not let brake fluid enter into your

eyes. If brake fluid gets in your eyes,

flush your eyes with clean water for

at least 15 minutes and get immediate

medical attention.

NOTICE

Do not allow brake fluid to contact

the vehicle’s body paint, as it will

result in paint damage.

NEVER use brake fluid which has

been exposed to open air for an

extended time, as its quality cannot

be guaranteed.

Do not use the wrong type of brake

fluid. A few drops of mineral based

oil, such as engine oil in your brake

system can damage brake system

parts.

Information

Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).

9-34

TIRES AND WHEELS

WARNING

Tire failure may cause loss of

vehicle control resulting in an

accident. To reduce risk of SERIOUS

INJURY or DEATH, take the

following precautions:

Inspect your tires monthly for

proper inflation as well as wear

and damage.

The recommended cold tire

pressure for your vehicle can be

found in this manual and on the

tire label located on the driver’s

side center pillar. Always use a

tire pressure gauge to measure

tire pressure. Tires with too

much or too little pressure wear

unevenly causing poor handling.

Check the pressure of the spare

tire every time you check the

pressure of the other tires on

your vehicle.

Replace tires that are worn, show

uneven wear, or are damaged.

Worn tires can cause loss of

braking effectiveness, steering

control, or traction.

ALWAYS replace tires with the

same size, type, construction and

tread pattern as each tire that

was originally supplied with this

vehicle. Using tires and wheels

other than the recommended

sizes could cause unusual

handling characteristics, poor

vehicle control, or negatively

affect your vehicle’s Anti-Lock

Brake System (ABS) resulting in a

serious accident.

Tire Care

For proper maintenance, safety, and

maximum fuel economy, you must

always maintain recommended

tire inflation pressures and stay

within the load limits and weight

distribution recommended for your

vehicle.

OTM010024L

All specifications (sizes and

pressures) can be found on a label

attached to the driver’s side center

pillar.

Recommended Cold Tire

Inflation Pressures

All tire pressures (including the

spare) should be checked when the

tires are cold. “Cold tires” means the

vehicle has not been driven for at

least three hours or driven less than 1

mile (1.6 km).
Warm tires normally exceed

recommended cold tire pressures

by 4 to 6 psi (28 to 41 kPa). Do not

release air from warm tires to adjust

the pressure or the tires will be

under-inflated. For recommended

inflation pressure, refer to “Tire and

Wheels” section in chapter 2.

9-35

WARNING

Recommended pressures must be

maintained for the best ride, vehicle

handling, and minimum tire wear.
Over-inflation or under-inflation

can reduce tire life, adversely

affect vehicle handling, and lead to

sudden tire failure that could result

in loss of vehicle control resulting in

an accident.
Severe under-inflation can lead

to severe heat build-up, causing

blowouts, tread separation and

other tire failures that can result in

the loss of vehicle control resulting

in an accident. This risk is much

higher on hot days and when

driving for long periods at high

speeds.

CAUTION

Under-inflation results in

excessive wear, poor handling

and reduced fuel economy.

Wheel deformation is also

possible. Keep your tire pressures

at the proper levels. If a tire

frequently needs refilling, have

it checked by an authorized

HYUNDAI dealer.

Over-inflation produces a harsh

ride, excessive wear at the center

of the tire tread, and a greater

possibility of damage from road

hazards.

Check Tire Inflation Pressure

Check your tires, including the spare

tire, once a month or more.

How to check

Use a good quality tire pressure

gauge to check tire pressure. You

can not tell if your tires are properly

inflated simply by looking at them.

Radial tires may look properly

inflated when they are under-

inflated.
Remove the valve cap from the tire

valve stem. Press the tire gauge

firmly onto the valve to get a

pressure measurement. If the cold

tire inflation pressure matches the

recommended pressure on the tire

and loading information label, no

further adjustment is necessary. If

the pressure is low, add air until you

reach the recommended pressure.

Make sure to put the valve caps

back on the valve stems. Without

the valve cap, dirt or moisture could

get into the valve core and cause

air leakage. If a valve cap is missing,

install a new one as soon as possible.
If you overfill the tire, release air by

pushing on the metal stem in the

center of the tire valve. Recheck the

tire pressure with the tire gauge. Be

sure to put the valve caps back on

the valve stems. Without the valve

cap, dirt or moisture could get into

the valve core and cause air leakage.

If a valve cap is missing, install a new

one as soon as possible.

Maintenance

9-36

Tire Rotation

To equalize tread wear, HYUNDAI

recommends that the tires

be rotated according to the

maintenance schedule or sooner if

irregular wear develops.
During rotation, check the tires for

correct balance.
When rotating tires, check for

uneven wear and damage. Abnormal

wear is usually caused by incorrect

tire pressure, improper wheel

alignment, out-of-balance wheels,

severe braking or severe cornering.

Look for bumps or bulges in the

tread or side of the tire. Replace

the tire if you find any of these

conditions. Replace the tire if fabric

or cord is visible. After rotation, be

sure to bring the front and rear tire

pressures to specification and check

lug nut tightness (proper torque is

79~94 lbf·ft [11~13 kgf·m]).

OHI078078

Disc brake pads should be inspected

for wear whenever tires are rotated.

unsymmetrical tire is distinguishable.
When installing an unsymmetrical
tire, be sure to install the side marked
“outside” face the outside. If the side
marked “inside” is installed on the
outside, it will have a negative effect
on vehicle performance.

WARNING

Do not use the compact spare

tire for tire rotation.

Do not mix bias ply and radial ply

tires under any circumstances.

This may cause unusual handling

characteristics that may cause

loss of vehicle control resulting in

an accident.

9-37

Wheel Alignment and Tire

Balance

The wheels on your vehicle were

aligned and balanced carefully at the

factory to give you the longest tire

life and best overall performance.
In most cases, you will not need to

have your wheels aligned again.

However, if you notice unusual tire

wear or your vehicle pulling one way

or the other, the alignment may need

to be reset.
If you notice your vehicle vibrating

when driving on a smooth road, your

wheels may need to be rebalanced.

NOTICE

Incorrect wheel weights can

damage your vehicle’s aluminum

wheels. Use only approved wheel

weights.

Tire Replacement

Tread wear indicator

OHI078080

If the tire is worn evenly, a tread

wear indicator will appear as a solid

band across the tread. This shows

there is less than 1/16 in. (1.6 mm) of

tread left on the tire. Replace the tire

when this happens.
Do not wait for the band to appear

across the entire tread before

replacing the tire.

WARNING

To reduce the risk of DEATH or

SERIOUS INJURY:

Replace tires that are worn, show

uneven wear, or are damaged.

Worn tires can cause loss of

braking effectiveness, steering

control, and traction.

Always replace tires with the

same size as each tire that was

originally supplied with this

vehicle. Using tires and wheels

other than the recommended

sizes could cause unusual

handling characteristics, poor

vehicle control, or negatively

affect your vehicle’s Anti-Lock

Brake System (ABS) resulting in a

serious accident.

When replacing tires (or wheels),

it is recommended to replace

the two front or two rear tires (or

wheels) as a pair. Replacing just

one tire can seriously affect your

vehicle’s handling.

Tires degrade over time, even

when they are not being used.

Regardless of the remaining

tread, HYUNDAI recommends

that tires be replaced after six (6)

years of normal service.

Heat caused by hot climates or

frequent high loading conditions

can accelerate the aging process.

Failure to follow this warning

may cause sudden tire failure,

which could lead to a loss of

vehicle control resulting in an

accident.

Maintenance

9-38

Compact spare tire replacement

(if equipped)

A compact spare tire has a shorter

tread life than a regular size tire.

Replace it when you can see the

tread wear indicator bars on the tire.

The replacement compact spare tire

should be the same size and design

tire as the one provided with your

new vehicle and should be mounted

on the same compact spare tire

wheel. The compact spare tire is

not designed to be mounted on a

regular size wheel, and the compact

spare tire wheel is not designed for

mounting a regular size tire.

WARNING

The original tire should be repaired

or replaced as soon as possible to

avoid failure of the spare and loss

of vehicle control resulting in an

accident.The compact spare tire

is for emergency use only. Do not

operate your vehicle over 50 mph

(80 km/h) when using the compact

spare tire.

Wheel Replacement

When replacing the metal wheels

for any reason, make sure the new

wheels are equivalent to the original

factory units in diameter, rim width

and offset.

Tire Traction

Tire traction can be reduced if you

drive on worn tires, tires that are

improperly inflated or on slippery

road surfaces. Tires should be

replaced when tread wear indicators

appear. To reduce the possibility of

losing control, slow down whenever

there is rain, snow or ice on the road.

Tire Maintenance

In addition to proper inflation,

correct wheel alignment helps to

decrease tire wear. If you find a tire

is worn unevenly, have your dealer

check the wheel alignment.
When you have new tires installed,

make sure they are balanced. This

will increase vehicle ride comfort

and tire life. Additionally, a tire

should always be rebalanced if it is

removed from the wheel.

9-39

Tire Sidewall Labeling

This information identifies and

describes the fundamental

characteristics of the tire and also

provides the tire identification

number (TIN) for safety standard

certification. The TIN can be used to

identify the tire in case of a recall.

B0464EU01

1. Manufacturer or brand name

Manufacturer or brand name is

shown.

2. Tire size designation

A tire’s sidewall is marked with a

tire size designation. You will need

this information when selecting

replacement tires for your car.

The following explains what the

letters and numbers in the tire size

designation mean.

Example tire size designation:
(These numbers are provided as

an example only; your tire size

designator could vary depending on

your vehicle.)

Tire speed ratings

The chart below lists many of the

different speed ratings currently

being used for passenger vehicle

tires. The speed rating is part of the

tire size designation on the sidewall

of the tire. This symbol corresponds

to that tire’s designed maximum safe

operating speed.

Speed Rating

Symbol

Maximum Speed

112 mph (180 km/h)

118 mph (190 km/h)

168 mph (270 km/h)

186 mph (300 km/h)

3. Checking tire life (TIN : Tire

Identification Number)

Any tires that are over six years old,

based on the manufacturing date,

(including the spare tire) should be

replaced by new ones. You can find

the manufacturing date on the tire

sidewall (possibly on the inside of

the wheel), displaying the DOT Code.

The DOT Code is a series of numbers

on a tire consisting of numbers and

English letters. The manufacturing

date is designated by the last four

digits (characters) of the DOT code.

DOT : XXXX XXXX OOOO

The front part of the DOT shows a

plant code number, tire size and

tread pattern and the last four

numbers indicate week and year

manufactured.
For example:
DOT XXXX XXXX 1523 represents that

the tire was produced in the 15th

week of 2023.

4. Tire ply composition and material

The number of layers or plies of

rubber-coated fabric in the tire. Tire

manufacturers also must indicate the

materials in the tire, which include

steel, nylon, polyester, and others.

The letter “R” means radial ply

construction; the letter “D“ means

diagonal or bias ply construction;

and the letter “B” means belted-bias

ply construction.

5. Maximum permissible inflation

pressure

This number is the greatest amount

of air pressure that should be put in

the tire. Do not exceed the maximum

permissible inflation pressure. Refer

to the Tire and Loading Information

label for recommended inflation

pressure.

6. Maximum load rating

This number indicates the maximum

load in kilograms and pounds that

can be carried by the tire. When

replacing the tires on the vehicle,

always use a tire that has the same

load rating as the factory installed

tire.

7. Uniform tire quality grading

Quality grades can be found where

applicable on the tire sidewall

between tread shoulder and

maximum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A

9-41

Tread wear

The tread wear grade is a

comparative rating based on the

wear rate of the tire when tested

under controlled conditions on a

specified government test course.

For example, a tire graded 150 would

wear one-and-a-half times (1½) as

well on the government course as a

tire graded 100.
The relative performance of tires

depends upon the actual conditions

of their use, however, and may

depart significantly from the norm

due to variations in driving habits,

service practices and differences in

road characteristics and climate.
These grades are molded on the

sidewalls of passenger vehicle tires.

The tires available as standard or

optional equipment on your vehicle

may vary with respect to grade.

Traction - AA, A, B & C

The traction grades, from highest

to lowest, are AA, A, B and C. Those

grades represent the tire’s ability to

stop on wet pavement as measured

under controlled conditions on

specified government test surfaces

of asphalt and concrete. A tire

marked C may have poor traction

performance.

WARNING

The traction grade assigned to

this tire is based on straightahead

braking traction tests, and does not

include acceleration, cornering,

hydroplaning, or peak traction

characteristics.

Temperature - A, B & C

The temperature grades are A (the

highest), B and C representing the

tire’s resistance to the generation

of heat and its ability to dissipate

heat when tested under controlled

conditions on a specified indoor

laboratory test wheel.
Sustained high temperature can

cause the material of the tire to

degenerate and reduce tire life,

and excessive temperature can

lead to sudden tire failure. Grades

B and A represent higher levels of

performance on the laboratory test

wheel than the minimum required

by law.

WARNING

The temperature grade for this

tire is established for a tire that

is properly inflated and not

overloaded. Excessive speed,

under-inflation, over-inflation, or

excessive loading, either separately

or in combination, can cause heat

build-up and possible sudden

tire failure. This may cause loss

of vehicle control resulting in an

accident.

recommended inflation pressure.

All Season Tires

HYUNDAI specifies all season

tires on some models to provide

good performance for use all year

round, including snowy and icy

road conditions. All season tires

are identified by ALL SEASON and/

or M+S (Mud and Snow) on the tire

sidewall. Snow tires have better

snow traction than all season tires

and may be more appropriate in

some areas.

Summer Tires

HYUNDAI specifies summer tires on

some models to provide superior

performance on dry roads. Summer

tire performance is substantially

reduced in snow and ice. Summer

tires do not have the tire traction

rating M+S (Mud and Snow) on

the tire side wall. If you plan to

operate your vehicle in snowy or icy

conditions, HYUNDAI recommends

the use of snow tires or all season

tires on all four wheels.

Snow Tires

If you equip your car with snow

tires, they should be the same size

and have the same load capacity as

the original tires. Snow tires should

be installed on all four wheels;

otherwise, poor handling may result.

Snow tires should carry 4 psi (28 kPa)

more air pressure than the pressure

recommended for the standard

tires on the tire label on the driver’s

side of the center pillar, or up to the

maximum pressure shown on the tire

sidewall, whichever is less. Do not

drive faster than 75 mph (120 km/h)

when your vehicle is equipped with

snow tires.

9-45

Radial-Ply Tires

Radial-ply tires provide improved

tread life, road hazard resistance

and smoother high speed ride. The

radial-ply tires used on this vehicle

are of belted construction, and are

selected to complement the ride

and handling characteristics of your

vehicle.
Radial-ply tires have the same load

carrying capacity, as bias-ply or

bias belted tires of the same size,

and use the same recommended

inflation pressure. Mixing of radial-

ply tires with bias-ply or bias belted

tires is not recommended. Any

combinations of radial-ply and bias-

ply or bias belted tires when used

on the same vehicle will seriously

deteriorate vehicle handling. The

best rule to follow is: Identical pairs

of radial-ply tires should always be

used as a set for the front tires and a

set for the rear tires.
Longer wearing tires can be more

susceptible to irregular tread wear.

It is very important to follow the tire

rotation interval in this chapter to

achieve the tread life potential of

these tires. Cuts and punctures in

radial-ply tires are repairable only in

the tread area, because of sidewall

flexing. Consult your tire dealer for

radial-ply tire repairs.

WARNING

Do not mix bias ply and radial ply

tires under any circumstances.

This may cause unusual handling

characteristics that may cause loss

of vehicle control resulting in an

accident.

Low Aspect Ratio Tires

(if equipped)

The aspect ratio is lower than 50 on

low aspect ratio tires.
Because low aspect ratio tires are

optimized for handling and braking,

their sidewall is a little stiffer than

a standard tire. Also low aspect

ratio tires tend to be wider and

consequently have a greater contact

patch with the road surface. In some

instances they may generate more

road noise compared with standard

tires.

Maintenance

9-46

CAUTION

The side wall of a low aspect ratio

tire is shorter than the normal one.

Thus, the low-aspect wheel and

tire are easily damaged. Follow the

below instructions.

When driving on a rough road or

driving off a road, be careful not

to damage the tires and wheels.

After driving, inspect the tires

and wheels.

When passing over a pothole,

speed bump, manhole, or curb

stone, drive the vehicle slowly so

as not to damage the tires and

wheels.

When there is an impact on a tire,

inspect the tire condition. Or,

you can contact an authorized

HYUNDAI dealer.

Inspect the tire condition and

pressure every 1,800 miles (3,000

km) to prevent tire damage.

It is difficult to recognize a tire

damage only with your eyes.

When there is a slight hint of a

tire damage, check and replace

the tire to prevent the damage

caused by air leakage.

When a tire is damaged while

driving on a rough road, off a

road, or over obstacles, such as a

pothole, manhole, or curb stone,

your warranty does not cover the

damage.

The tire information is specified

on the tire side wall.

A vehicle’s electrical system is protected

from electrical overload damage by

fuses.
This vehicle has 2 (or 3) fuse panels, one

located in the driver’s side panel bolster,

the other in the engine compartment.
If any of your vehicle’s lights,

accessories, or controls do not work,

check the appropriate circuit fuse. If a

fuse has blown, the element inside the

fuse will be melted or broken.
If the electrical system does not work,

first check the driver’s side fuse panel.

Before replacing a blown fuse, turn the

engine and all switches off, and then

disconnect the (-) battery terminal

(For plug-in hybrid vehicle) or battery

connector (For hybrid vehicle). Always

replace a blown fuse with one of the

same rating.
If the replacement fuse blows, this

indicates an electrical problem. Avoid

using the system involved. Immediately

consult an authorized HYUNDAI dealer.

Information

Three kinds of fuses are used: blade type
for lower amperage rating, cartridge
type, and multi fuse for higher amperage
ratings.

9-48

WARNING

NEVER replace a fuse with anything but

another fuse of the same rating.

A higher capacity fuse could cause

damage and possibly cause a fire.

Do not install a wire or aluminum

foil instead of the proper fuse -

even as a temporary repair. It may

cause extensive wiring damage and

possibly a fire.

NOTICE

Do not use a screwdriver or any other

metal object to remove fuses because

it may cause a short circuit and damage

the system.
