LIGHT BULBSUse only bulbs of the specified wattage.
✽
✽NOTICEAfter heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between 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 vehicle checked
by an authorized 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 movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattage rating. Otherwise, it may causedamage to the fuse or electric wiring system.
CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,consult an authorized HYUNDAIdealer. In many cases, it is difficult to replace vehicle light bulbsbecause other parts of the vehiclemust be removed before you canget to the bulb. This is especially true if you have to remove the head-light assembly to
get to the bulb(s).
Removing/installing
the headlight
assembly can result in damage to the vehicle.

 Halogen bulbs contain pressur-ized gas that will produce flying
pieces of glass if broken.
 Always handle them carefully, and avoid scratches and abra-
sions. If the bulbs are lit, avoid
contact with liquids. Never touch
the glass with bare hands.
Residual oil may cause the bulb
to overheat and burst when lit. A
bulb should be operated only
when installed in a headlight.

APPEARANCE CAREExterior careExterior 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.Finish maintenanceWashing
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 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 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, may be used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
CAUTION
 Do not use strong soap, chemical
detergents or hot water, and donot wash the vehicle in directsunlight or when the body of the vehicle is warm.
 Be careful when washing the side windows of your vehicle.Especially, with high-pressure water, water may leak through thewindows and wet the interior.
 To prevent damage to the plastic parts and lamps, do not cleanwith chemical solvents or strong detergents.
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
 Water washing in the engine com- partment including high pressurewater washing may cause the fail-ure of electrical circuits or engineand related components locatedin the engine compartment.
 Never allow water or other liquids to come in contact with electri-cal/electronic components andair duct inside the vehicle as this may damage them.

Maintenance
Aluminum wheel maintenance The aluminum wheels are coated with a
clear protective finish.
 Do not use any abrasive cleaner, pol-ishing compound, solvent, or wire
brushes on aluminum 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 cleaners containing acid or acid detergents. It may damage
and corrode the aluminum wheels
coated with a clear protective finish.
Corrosion protectionProtecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we produce 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 corrosion
on your car are:
 Road salt, dirt and moisture that isallowed to accumulate underneath the
car.
 Removal of paint or protective coatings by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.
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.
