Checking the washer fluid
level  

The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary.
Plain water may be used if washer
fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.

Information 

A warning message is displayed in the
instrument cluster LCD display if the
washer fluid level in the reservoir is
nearly empty.  Have the washer fluid
reservoir refilled.
For more information, refer to “LCD
Display Messages” in chapter 3.

Coolant
• Do not use radiator coolant or

antifreeze in the washer fluid
reservoir.

• Radiator coolant can severely

obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control or
damage to paint and body trim.

• Windshield Washer fluid agents

contain some amounts of alco-
hol and can be flammable under
certain circumstances. Do not
allow sparks or flame to contact
the washer fluid or the washer
fluid reservoir. Damage to the
vehicle or occupants could
occur.

• Windshield washer fluid is poi-

sonous to humans and animals.
Do not drink and avoid contact-
ing windshield washer fluid.
Serious injury or death could
occur.

Blade inspection

Information 

Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean.  

Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.

To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.

Blade replacement  

When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.

To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers manu-
ally.

The use of a non-specified wiper
blade could result in wiper mal-
function and failure.

Front windshield wiper blade

For your convenience, move the
windshield wiper blades to the serv-
ice position as follows;
After turning off the engine, move the
wiper switch to the single wiping
(MIST) position within 20 seconds
and hold the switch more than 2 sec-
onds until the wiper blade is in the
fully up position.

Do not allow the wiper arm to fall
against the windshield, since it may
chip or crack the windshield.

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.

Recommended cold tire infla-
tion 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
1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in section
8.

All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.

• Underinflation also results in

excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is pos-
sible. Keep your tire pressures
at the proper levels. If a tire fre-
quently needs refilling, we rec-
ommend that the system be
checked by an authorized retail-
er of Genesis Branded products.

• Overinflation produces a harsh

ride, excessive wear at the cen-
ter of the tire tread, and a greater
possibility of damage from road
hazards.

Tire underinflation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

WARNING

7-40

Maintenance

• Warm tires normally exceed rec-

ommended cold tire pressures
by 28 to 41 kPa (4 to 6 psi). Do
not release air from warm tires
to adjust the pressure or the
tires will be underinflated.

• Be sure to reinstall the tire infla-

tion valve caps. 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.

Tire pressure
Always observe the following:
• Check tire pressure when the

tires are cold. (After vehicle has
been parked for at least three
hours or hasn't been driven
more than 1.6 km (1 mile) since
startup.)

• Check the pressure of your

spare tire each time you check
the pressure of other tires.

• Never overload your vehicle. Be

careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.

• Worn, old tires can cause acci-

dents. If your tread is badly
worn, or if your tires have been
damaged, replace them.

Checking tire inflation pres-
sure

Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.

How to check

Use a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).

NOTICE

NOTICE

Tire inflation

Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.

WARNING

7-41

07

Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly 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 adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
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 gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.

• Inspect your tires frequently

for proper inflation as well as
wear and damage. Always use
a tire pressure gauge.

• Tires with too much or too little

pressure wear unevenly caus-
ing poor handling, loss of vehi-
cle control, and sudden tire
failure leading to accidents,
injuries, and even death. The
recommended cold tire pres-
sure for your vehicle can be
found in this manual and on
the tire label located on the dri-
ver's side center pillar.

• Worn tires can cause acci-

dents. Replace tires that are
worn, show uneven wear, or
are damaged.

• Remember to check the pres-

sure of your spare tire.
Genesis Branded Vehicle rec-
ommends that you check the
spare every time you check the
pressure of the other tires on
your vehicle.

WARNING

Tire rotation 

To equalize tread wear, it is recom-
mended that the tires be rotated
every 12,000 km (7,500 miles) 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 pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either 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.
Refer to “Tire and wheels” in section 8.

Disc brake pads should be inspected
for wear whenever tires are rotated.

Information 

If your tire is unsymmetrical tire,
check the outside and inside marked
in tire.
If the inside tire is installed on outside,
the vehicle driving and wear perform-
ance may be damaged.

Wheel alignment and tire bal-
ance  

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.

Improper wheel weights can dam-
age your vehicle's aluminum
wheels. Use only approved wheel
weights.

Tire replacement

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 1.6 mm (1/16 in.) 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 replac-
ing the tire.

When replacing the tires, recheck
and tighten the wheel nuts after
driving about 1,000 km (620
miles). If the steering wheel
shakes or the vehicle vibrates while
driving, the tire is out of balance.
Align the tire balance. If the prob-
lem is not solved, we recommend
that you contact an authorized
retailer of Genesis Branded prod-
ucts.

NOTICE

NOTICE

• Do not use the compact spare

tire for tire rotation.

• Do not mix bias ply and radial

ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that could result in death,
severe injury, or property
damage.

WARNING

OHI076053

Tread wear indicator

7-44

Maintenance

Compact spare tire replacement 

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 mount-
ing a regular size tire.

(Continued)
• The ABS works by comparing

the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) (if equipped) to work
irregularly.

• For replacement with an

unsymmetrical tire,

you

should check the outside/
inside of the unsymmetrical
tire. Make sure that the out-
side mark should locate in the
outward direction. If not, it
may adversely affect the vehi-
cle performance, riding com-
fort, and tire worn-out rates.

Replacing tires
• Driving on worn-out tires is

very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.

• Your vehicle is equipped with

tires designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tire and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tires, be sure to equip all
four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capacity.

• The use of any other tire size

or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tire clearance, snow tire
clearance, and speedometer
reliability.

• It is best to replace all four

tires at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tires as a pair.
Replacing just one tire can
seriously affect your vehicle’s
handling.
