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
The headlamp 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
headlamp on. The removable level
may differ depending on lamp size,
lamp position and environmental con-
dition. However, if moisture is not
removed, we recommend that your
vehicle is inspected by an authorized
HYUNDAI dealer.
Information - 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,
have your vehicle checked by an
authorized HYUNDAI dealer. i
i
Prior to replacing a lamp,
depress the brake pedal,
move the shift lever into P
(Park) apply the parking
brake, place the igntion
switch to the LOCK/OFF posi-
tion, 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.

Maintenance
Cleaning the upholstery andinterior trim
Vinyl (if equipped)
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Using anything but recommended
cleaners and procedures may
affect the fabric’s appearance and
fire-resistant properties.
Leather (if equipped)
Feature of Seat Leather
- Leather is made from the outerskin of an animal, which goes
through a special process to be
available for use. Since it is a nat-
ural object, each part differs in
thickness or density. Wrinkles
may appear as a natural result of
stretching and shrinking depend-
ing on the temperature and
humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driv-
ing comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
product.
NOTICE
Wrinkles or abrasions which
appear naturally from usage
are not covered by warranty.
Belts with metallic acces-
sories, zippers or keys inside
the back pocket may damage
the seat fabric.
Make sure not to wet the seat.
It may change the nature of
natural leather.
Jeans or clothes which could
bleach may contaminate the
surface of the seat covering
fabric.
