G200700BUN-EA 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 widthand offset. G200800AUN-EA
Tyre traction
Tyre traction can be reduced if you
drive on worn tyres, tyres that are
improperly inflated or on slippery
road surfaces. Tyres 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.
G200900AUN-EA
Tyre maintenance In addition to proper inflation, correct wheel alignment helps to decrease
tyre wear. If you find a tyre is worn
unevenly, have your dealer check thewheel alignment.
When you have new tyres installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tyre life. Additionally, a tyre should
always be rebalanced if it is removedfrom the wheel.(Continued)
The use of any other tyre size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tyre clearance, snow tyre
clearance, and speedometer
reliability.
It is best to replace all four tyres at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tyres as a pair.Replacing just one tyre can
seriously affect your vehicle’shandling.
The ABS works by comparing the speed of the wheels. Tyre
size can affect wheel speed.
When replacing tyres, all 4
tyres must use the same size
originally supplied with the
vehicle. Using tyres of a dif-
ferent size can cause the ABS
(Anti-lock Brake System) and
ESP (Electronic Stability
Program) (if equipped) to
work irregularly.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tyre clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.

LIGHT BULBS
G220000AFD-EA
Use only the bulbs of the specified wattage.
All bulbs are available from yourHYUNDAI dealers Parts Department.
✽✽ NOTICE
After washing or driving through heavy rain, condensation may form in the head
and tail lamp lenses. This condition is
caused by the temperature differencebetween the lamp inside and outside.
This is similar to the condensation on
your windows inside your vehicle during
the rain and doesn’t indicate a problem
with your vehicle. If the water leaks into
the lamp bulb circuitry, have the vehiclechecked by an authorised HYUNDAI
dealer.
WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the ignition switch is turned to
the “LOCK” position and turn off
the lights to avoid sudden move-
ment of the vehicle and burning
your fingers or receiving an electric
shock.
CAUTION
Be sure to replace the burned-out bulb with one of the same wattage rating. Otherwise, it may cause damage to the fuse or electricwiring system.
CAUTION
If you don’t have necessary tools,
the correct bulbs and the expertise,consult an authorised HYUNDAI dealer. In many cases, it is difficult
to replace vehicle light bulbsbecause other parts of the vehicle must be removed before you can get to the bulb. This is especially
true if you have to remove the head- light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to the vehicle.

Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning andcaution statements that appear on thelabel.

Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughlyand frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are keptclear and clean. Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
WARNING -
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 for-
ward speed.
CAUTION
Do not use strong soap, chemical detergents or hot water, and do not
wash the vehicle in direct sunlight or when the body of the vehicle is warm.CAUTION
Water washing in the engine com- partment including high pressure
water washing may cause the fail- ure of electrical circuits located inthe engine compartment.
Never allow water or other liquids to come in contact with electri-cal/electronic components inside the vehicle as this may damagethem.

Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated 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 underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Payspecial 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. G230106AUN-EA
Aluminium wheel maintenance
The aluminium wheels are coated with a
clear protective finish.
Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminium wheels. They
may scratch or damage the finish.
Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high- speed car wash brushes.
Do not use any acid detergent. It may damage and corrode the aluminium
wheels coated with a clear protectivefinish.
WARNING
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 for-
ward speed.

Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo
my 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.
