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,
lamps could appear frosty. This condi-
tion is caused by the temperature dif-
ference between the lamp inside and
the outside temperature. This is simi-
lar to the condensation on your win-
dows 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
your vehicle checked by an authorized
HYUNDAI dealer.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorized
HYUNDAI dealer.
• The parking lamp may not turn on when the parking lamp switch is
turned on, but the parking lamp
and headlamp switch may turn on
when the headlamp switch is turned
on. This may be caused by network
failure or vehicle electrical control
system malfunction. If this occurs,
we recommend the system be
checked by an authorized
HYUNDAI dealer.

Prior to replacing a lamp, shift
to P (Park), apply the parking
brake, place the POWER but-
ton in the OFF position and
take the key with you when
leaving the vehicle to avoid
sudden movement of the vehi-
cle 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.
Do not use any high-pressure noz- zles, which induce either one-
direct water stream or water
swirling.
Protecting your vehicle’s finish
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.

Maintenance
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish. Do not use strong soap, chemi-
cal detergents or hot water, and
do not wash the vehicle in direct
sunlight 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
the windows and wet the interi-
or.
To prevent damage to the plastic parts, do not clean with chemi-
cal solvents or strong deter-
gents. Water washing in the fuel cell
power module compartment
including high pressure water
washing may cause the failure
of electrical circuits located in
the fuel cell power module 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.
NOTICE
NOTICE
OFE078045N
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.
WARNING

Maintenance
Waxing
A good coat of wax provides a barri-
er between your paint and environ-
mental contamination.
Keeping a good coat of wax on your
vehicle will help protect it.
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 materi-
als 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 wax-
ing. 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.
Repairing your vehicle’s finish
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.

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 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 rust-
ing.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Do not use abrasive cleaner, pol-
ishing compound, solvent, or
wire brushes on aluminum
wheels.
Clean the wheel when it has cooled.
Use only a mild soap or neutral detergent, and rinse thoroughly
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.
NOTICE
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.

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 isallowed to accumulate underneath
the vehicle.
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 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.
