Headlight (HID/LED type) bulb
replacement
If the light bulb is not operating, have the
vehicle checked by an authorized
HYUNDAI dealer.
✽NOTICE
HID/LED lamps have superior per-
formance vs. halogen bulbs. HID/LED
lamps are estimated by the manufactur-
er to last twice as long or longer than
halogen bulbs depending on their fre-
quency of use. They will probably
require replacement at some point in the
life of the vehicle. Cycling the head-
lamps on and off more than typical use
will shorten HID/LED lamps life. HID/
LED lamps do not fail in the same man-
ner as halogen incandescent lamps. If a
headlamp goes out after a period of
operation but will immediately relight
when the headlamp switch is cycled it is
likely the HID/LED lamp needs to be
replaced. HID/LED lighting compo-
nents are more complex than conven-
tional halogen bulbs thus have higher
replacement cost.

WARNING- Halogen bulbs
• 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.

Traffic Change (For Europe)
The low beam light distribution is asym-
metric.
If you go abroad to a country with oppo-
site traffic direction, this asymmetric part
will dazzle oncoming car driver. To pre-
vent dazzle, ECE regulation demand
several technical solutions (ex. automatic
change system, adhesive sheet, down
aiming). This headlamps are designed
not to dazzle opposite drivers. So, you
need not change your headlamps in a
country with opposite traffic direction.

caution statements that appear on the
label.
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 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.
APPEARANCE CARE
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.
• Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure
water, water may leak through the
windows and wet the interior.
• To prevent damage to the plastic
parts and lamps, do not clean
with 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 pressure
water washing may cause the fail-
ure of electrical circuits or engine
and related part located in the
engine compartment.
• Never allow water or other liquids
to come in contact with electri-
cal/electronic components and
air duct inside the vehicle as this
may damage them.

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.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.
✽NOTICE
If your vehicle is damaged and requires
any metal repair or replacement, be sure
the body shop applies anti-corrosion
materials 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 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 preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
CAUTION
• 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-plated
or anodized aluminum parts. This
may result in damage to the pro-
tective coating and cause discol-
oration or paint deterioration.

Maintenance
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 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.
Aluminum or chrome wheel mainte-
nance
The aluminum or chrome wheels are
coated with a clear protective finish.
• Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminum or chrome
wheels. They may scratch or damage
the finish.
• Clean the wheel when it has cooled.
• 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 alkaline or acid deter-
gent. It may damage and corrode the
aluminum or chrome wheels coated
with a clear protective finish.
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.

Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we 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 corrosion
on your car are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath the
vehicle.
• Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.High-corrosion areas
If you live in an area where your car is
regularly exposed to corrosive materials,
corrosion protection is particularly impor-
tant. Some of the common causes of
accelerated corrosion 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, particularly when tempera-
tures are just above freezing. In such
conditions, the corrosive material is kept
in contact with the car surfaces by mois-
ture 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 accelerate
corrosion of parts that are not properly
ventilated so the moisture can be dis-
persed. For all these reasons, it is par-
ticularly important to keep your car clean
and free of mud or accumulations of
other materials. This applies not only to
the visible surfaces but particularly to the
underside of the car.
