Maintenance

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 condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
by an authorized HYUNDAI dealer.
WARNING
• Prior to replacing a lamp, depress
the foot brake, move the shift button
into P (Park) apply the parking brake,
place the ignition switch to 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.
