Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.Information
After heavy driving, rain or washing,
headlamp and trunk lenses could
appear frosty. This condition is caused
by the temperature difference
between the lamp inside and the out-
side temperature. This is similar to the
condensation on your windows inside
your vehicle during the rain and does-
n’t indicate a problem with your vehi-
cle. If the water leaks into the lamp
bulb circuitry, have your vehicle
checked by an authorized HYUNDAI
dealer.
- Desiccant (if equipped)
This vehicle is equipped with desic-
cant to reduce fogging inside the head-
lamp due to moisture.
The desiccant is consumable and its
performance may change based on the
used period or environment.
If fogging inside the headlamp due to
moisture continues for a long time, we
recommend that you consult an
authorized HYUNDAI dealer. After
inspection, you may receive proper
service according to the warranty pol-
icy.
i
Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the igntion switch to the
LOCK/OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

Exterior Care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label.
High-pressure washing
When using high-pressure wash-
ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers)or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
Finish maintenance
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, 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 kept clear 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, should be
used. After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.

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.
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body
shop applies anti-corrosion mate-
rials 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.
NOTICE
Wiping dust or dirt off the
body with a dry cloth will
scratch the finish.
Do not use steel wool, abra-
sive cleaners, or strong deter-
gents containing highly alka-
line or caustic agents on
chrome-plated or anodized
aluminum parts. This may
result in damage to the pro-
tective coating and cause dis-
coloration or paint deteriora-
tion.
CAUTION

7-80
Maintenance
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 rust-
ing.
Aluminum wheel maintenance
The aluminum wheels are 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, HYUNDAI produces cars
of the highest quality. However, this is
only part of the job. To achieve the
long-term corrosion resistance your
vehicle can deliver, the owner’s
cooperation and assistance is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
Road salt, dirt and moisture that is allowed to accumulate underneath
the vehicle.
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.
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
Do not use abrasive cleaner,
polishing compound, solvent,
or wire brushes on aluminum
wheels.
Clean the wheel when it has
cooled.
Use only a mild soap or neu-
tral detergent, and rinse thor-
oughly with water. Also, clean
the wheels after driving on
salted roads.
Do not wash the wheels with
high-speed car wash brushes.
Do not use any cleaners con-
taining acid or alkaline deter-
gents.

Maintenance
High-corrosion areas
If you live in an area where your vehi-
cle 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, partic-
ularly when temperatures are just
above freezing. In such conditions,
the corrosive material is kept in con-
tact with the car surfaces by moisture
that is slow to evaporate.
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 corrosion.
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed. For all these rea-
sons, it is particularly important to
keep your vehicle clean and free of
mud or accumulations of other mate-
rials. This applies not only to the vis-
ible surfaces but particularly to the
underside of the vehicle.
To help prevent corrosion
Keep your car clean
The best way to prevent corrosion is
to keep your vehicle clean and free
of corrosive materials. Attention to
the underside of the vehicle is partic-
ularly 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 vehicle at least
once a month and be sure to clean
the underside thoroughly when
winter is over.
