• Water washing in the engine

compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.

• Never allow water or other liquids

to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them.

Waxing

Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster. Removing oil, tar, and
similar materials with a spot remover
will usually strip the wax from the fin-
ish. Be sure to re-wax these areas
even if the rest of the vehicle does
not yet need waxing.

• Wiping dust or dirt off the body

with a dry cloth will scratch the
finish.

• Do not use steel wool, abrasive

cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plat-
ed or anodized aluminum parts.
This may result in damage to the
protective coating and cause
discoloration or paint deteriora-
tion.

NOTICE

NOTICE

Wet brakes
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.

WARNING

Maintenance

Finish damage repair 

Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.

Information 

If your vehicle is damaged and
requires any metal repair or replace-
ment, be sure the body shop applies
anti-corrosion materials to the parts
repaired or replaced.  

Bright-metal maintenance

• To remove road tar and insects,

use a tar remover, not a scraper or
other sharp object.

• To protect the surfaces of bright-

metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.

• During winter weather or in coastal

areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.

Underbody maintenance

Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, acceler-
ated rusting can occur on underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with
rust protection.
Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end
of each winter.
Pay special attention to these areas
because it is difficult to see all the
mud and dirt. It will do more harm
than good to wet down the road
grime without removing it. The lower
edges of doors, rocker panels, and
frame members have drain holes
that should not be allowed to clog
with dirt; trapped water in these
areas can cause rusting.

i

After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while main-
taining a slow forward speed.

WARNING

Aluminum wheel 
maintenance  

The aluminum wheels are coated
with a clear protective finish.
• Do not use any abrasive cleaner,

polishing compound, solvent, or
wire brushes on aluminum wheels.
They may scratch or damage the
finish.

• Clean the wheel when it has

cooled.

• Use only a mild soap or neutral

detergent, and rinse thoroughly
with water. Also, be sure to clean
the wheels after driving on salted
roads. This helps prevent corro-
sion.

• Avoid washing the wheels with

high-speed car wash brushes.

• Do not use any alkaline or acid

detergent. It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.

Corrosion protection

Protecting your vehicle from corro-
sion

By using the most advanced design
and construction practices to combat
corrosion, we produces cars of the
highest quality. However, this is only
part of the job. To achieve the long-
term corrosion resistance your vehi-
cle can deliver, the owner's coopera-
tion and assistance is also required.

Common causes of corrosion

The most common causes of corro-
sion on your car are:
•  Road salt, dirt and moisture that is

allowed to accumulate underneath
the car.

• Removal of paint or protective

coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.

High-corrosion areas

If you live in an area where your car
is regularly exposed to corrosive
materials, corrosion protection is
particularly important. Some of the
common causes of accelerated cor-
rosion are road salts, dust control
chemicals, ocean air and industrial
pollution.

Moisture breeds corrosion

Moisture creates the conditions in
which corrosion is most likely to occur.
For example, corrosion is accelerated
by high humidity, particularly when
temperatures are just above freezing.
In such conditions, the corrosive mate-
rial is kept in contact with the car sur-
faces by moisture that is slow to evap-
orate.
Mud is particularly corrosive because
it is slow to dry and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still
retain the moisture and promote corro-
sion.
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed.

7-80

Maintenance

For all these reasons, it is particular-
ly important to keep your car clean
and free of mud or accumulations of
other materials. This applies not only
to the visible surfaces but particular-
ly to the underside of the car.

To help prevent corrosion

You can help prevent corrosion from
getting started by observing the fol-
lowing:

Keep your car clean
The best way to prevent corrosion is
to keep your car clean and free of
corrosive materials. Attention to the
underside of the car is particularly
important.

•  If you live in a high-corrosion area

— where road salts are used, near
the ocean, areas  with industrial
pollution, acid rain, etc.—, you
should take extra care to prevent
corrosion. In winter, hose off the
underside of your car at least once
a month and be sure to clean the
underside thoroughly when winter
is over.

•  When cleaning underneath the car,

give particular attention to the
components under the fenders and
other areas that are hidden from
view. Do a thorough job; just damp-
ening the accumulated mud rather
than washing it away will acceler-
ate corrosion rather  than prevent
it. Water under high pressure and
steam are particularly effective in
removing accumulated mud and
corrosive materials.

•  When cleaning lower door panels,

rocker  panels and frame mem-
bers, be sure that drain holes are
kept open so that moisture can
escape and not be trapped inside
to accelerate corrosion.

Keep your garage dry
Don't park your car in a damp, poor-
ly ventilated garage. This creates a
favorable environment for corrosion.
This is particularly true if you wash
your car in the garage or drive it into
the garage when it is still wet or cov-
ered with snow, ice or mud. Even a
heated garage can contribute to cor-
rosion unless it is well ventilated so
moisture is dispersed.

Keep paint and trim in good condi-
tion
Scratches or chips in the finish
should be covered with "touch-up"
paint as soon as possible to reduce
the possibility of corrosion. If bare
metal is showing through, the atten-
tion of a qualified body and paint
shop is recommended.

Bird droppings : Bird droppings are
highly corrosive and may damage
painted surfaces in just a few hours.
Always remove bird droppings as
soon as possible.

7-81

07

Don't neglect the interior
Moisture can collect under the floor
mats and carpeting to cause corro-
sion. Check under the mats periodi-
cally to be sure the carpeting is dry.
Use particular care if you carry fertil-
izers, cleaning materials or chemi-
cals in the car.
These should be carried only in
proper containers and any spills or
leaks should be cleaned up, flushed
with clean water and thoroughly
dried.

Interior care

Interior general precautions 

Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand clean-
er and air freshener from contacting
the interior parts because they may
cause damage or discoloration. If
they do contact the interior parts,
wipe them off immediately.
See the instructions that follow for
the proper way to clean vinyl.

Never allow water or other liquids
to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them.

Do not store any volatile liquids,
such as perfume, air freshener, or
deodorant, inside the vehicle. Any
contamination with those liquids
may damage the instrument clus-
ter area, crash pad, or leather/
plastic parts. If contaminated,
immediately clean the contaminat-
ed area with clean water.

When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alcohol
content solutions. If you use high
alcohol content solutions or
acid/alkaline detergents, the color
of the leather may fade or the sur-
face may get stripped off.

Cleaning the upholstery and
interior trim 

Vinyl 

Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.

Fabric 

Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.

Using anything but recommended
cleaners and procedures may
affect the fabric’s appearance and
fire-resistant properties.

Maintenance

Cleaning the lap/shoulder belt
webbing  

Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken it.

Cleaning the interior window
glass 

If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.

Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid.

NOTICE

07

The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
emission regulations.
There are three emission control
systems which are as follows.

(1) Crankcase emission control sys-

tem

(2) Evaporative emission control sys-

tem

(3) Exhaust emission control system

In order to assure the proper function
of the emission control systems, it is
recommended that you have your car
inspected and maintained by an
authorized retailer of Genesis Branded
products in accordance with the main-
tenance schedule in this manual.

Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
• To prevent the vehicle from mis-

firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch.

• After dynamometer testing is

completed, turn the ESC system
back on by pressing the ESC
switch again.

1. Crankcase emission control

system

The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.

2. Evaporative emission con-

trol system

The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.

Canister

Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.

Purge Control Solenoid Valve
(PCSV)

The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.

3. Exhaust emission control 

system

The Exhaust Emission Control System
is a highly effective system which con-
trols exhaust emissions while main-
taining good vehicle performance.

Engine exhaust gas precautions 
(carbon monoxide) 

• Carbon monoxide can be present

with other exhaust fumes. Therefore,
if you smell exhaust fumes of any
kind inside your vehicle, have it
inspected and repaired immediately.
If you ever suspect exhaust fumes
are coming into your vehicle, drive it
only with all the windows fully open.
Have your vehicle checked and
repaired immediately.

• Do not operate the engine in con-

fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.

• When the vehicle is stopped in an

open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.

• Never sit in a parked or stopped

vehicle for any extended time with
the engine running.

• When the engine stalls or fails to

start, excessive attempts to restart
the engine may cause damage to
the emission control system.

Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is dan-
gerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poisoning.

WARNING

Operating precautions for cat-
alytic converters (if equipped)

Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
• Use only UNLEADED FUEL for

gasoline engine.

• Do not operate the vehicle when

there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.

• Do not misuse or abuse the

engine. Examples of misuse are
coasting with the ignition off and
descending steep grades in gear
with the ignition off.

• Do not operate the engine at high

idle speed for extended periods (5
minutes or more).

• Do not modify or tamper with any

part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized retailer of Genesis
Branded products.

• Avoid driving with a very low fuel

level. If you run out of gasoline, it
could cause the engine to misfire
and result in excessive loading of
the catalytic converter.

Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.

• A hot exhaust system can

ignite flammable items under
your vehicle. Do not park, idle,
or drive the vehicle over or
near flammable objects, such
as dry grass, paper, leaves, etc.

• The exhaust system and cat-

alytic system are very hot
while the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or do not coat the
vehicle for corrosion control.
It may present a fire risk under
certain conditions.

Specifications & Consumer information

* Normal load : Up to 3 persons

When replacing tires, use the same size originally supplied with the
vehicle.
Using tires of a different size can damage the related parts or not work
properly.

Information

• It is permissible to add 3 psi to the standard tire pressure specification if cold-

er temperatures are expected soon. Tires typically loose 1 psi (7 kPa) for every
7°C (12°F) temperature drop. If extreme temperature variations are expected,
recheck   your tire pressure as necessary to keep them properly inflated.

• An air pressure generally decreases, as you drive up to a high-altitude area

above sea level. Thus, if you plan to drive a high-altitude area, check the tire
pressures in advance. If necessary, inflate them to a proper level. (Air inflation
per altitude: +10 kPa/1km or +2.4psi/1mile )

: Engine oils labeled Energy Conserving Oil are now available. Along with other

addition+al benefits, they contribute to fuel economy by reducing the amount of fuel
necessary to overcome engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they can offer significant cost and
energy savings.

Recommended SAE viscosity number   

Always be sure to clean the area around any filler plug, drain plug, or
dipstick before checking or draining any lubricant. This is especially
important in dusty or sandy areas and when the vehicle is used on
unpaved roads. Cleaning the plug and dipstick areas will prevent dirt
and grit from entering the engine and other mechanisms that could be
damaged.

Engine oil viscosity (thickness) has an effect on fuel economy and cold weath-
er operating (engine start and engine oil flow ability). Lower viscosity engine
oils can provide better fuel economy and cold weather performance; howev-
er, higher viscosity engine oils are required for satisfactory lubrication in hot
weather. Using oils of any viscosity other than those recommended could
result in engine damage. When choosing an oil, consider the range of temper-
ature your vehicle will be operated in before the next oil change. Proceed to
select the recommended oil viscosity from the chart.

: For better fuel economy, it is recommended to use the engine oil of a viscosity

grade SAE 5W-30. However, if the engine oil is not available in your country, select
the proper engine oil using the engine oil viscosity chart.

: For the Lambda 3.3 T. GDI / Tau 5.0 GDI, we recommend you to use high-grade

gasoline (above RON 96). You may still use other types of gasoline. However, those
may negatively affect your vehicle power and fuel economy.
