Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
chapter 8 and replace them if necessary.
Also check all ignition wiring and
components to be sure they are not
cracked, worn or damaged in any way.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of antifreeze as these may damage the
paint finish.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when
there is an accumulation of snow or
ice around or near the rear brakes or
if the brakes are wet. If there is a risk
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Don't place foreign objects
or materials in the engine
compartment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved de-
icing fluid to remove the ice. If the lock
is frozen internally, you may be able to
thaw it out by using a heated key. Handle
the heated key with care to avoid injury.

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 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, have the vehicle
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.
• When the bulb is disconnected or the
lamp connector is removed while the
lamp is operating normally, the fuse
box electronics may recognize the
lamp as a malfunction. Therefore, a
fault record for the lamp may remain
in the Diagnostic Trouble Code (DTC)
recorded in the fuse box.
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 electrical wiring system.
Information
The headlamp aiming should be adjusted
after an accident or after the headlamp
assembly is reinstalled at an authorized
HYUNDAI dealer.
