We recommend that you 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
headlight assembly to get to the bulb(s).
Removing/installing the headlight
assembly can result in damage to the
vehicle.
WARNING
Prior to replacing a light, depress the
foot brake, move the shift lever into the
N (Neutral, for Automatic transmission
vehicle) or neutral (for manual
transmission vehicle), apply the parking
brake, place the ignition switch in 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 fingers.
NOTICE
Be sure to replace the burned-out bulb
with one of the same wattage rating.
Otherwise, it may cause damage to the
fuse or electric wiring system.
i Information
The headlight and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night
in wet weather. This condition is caused
by temperature difference between the
lamp inside and outside and, it does not
indicate a problem with your vehicle.
When moisture condenses in the lamp,
it will be removed after driving with the
headlight on. The removable level may
differ depending on lamp size, lamp
position and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
by an authorized HYUNDAI dealer.

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 forward
speed.

NOTICE
• Water washing in the engine
compartment including high pressure
water washing may cause the failure
of electrical circuits located in the
engine compartment.
• Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
NOTICE
Matte paint finish vehicle
(if equipped)
Automatic car wash which uses
rotating brushes should not be used
as this can damage the surface of your
vehicle. A steam cleaner which washes
the vehicle surface at high temperature
may result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber towel
or sponge) when washing your vehicle
and dry with a microfiber towel. When
you hand wash your vehicle, you should
not use a cleaner that finishes with
wax. If the vehicle surface is too dirty
(sand, dirt, dust, contaminant, etc.),
clean the surface with water before
washing the car.
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 maintain
its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.

Maintenance
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 preservative 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, accelerated
rusting can occur on the 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. 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 the doors, rocker panels, and frame
members have drain holes that should
not clog with dirt; trapped water in these
areas can cause rusting.
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 forward
speed.
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 corrosion.
• Avoid washing the wheels with high-
speed car wash brushes.
• Do not use any alkaline or acid
detergent. It may damage and corrode
the aluminum wheels coated with a
clear protective finish.
