LIGHT BULBS
Bulb replacement precaution
Please keep extra bulbs on hand
with appropriate wattage ratings in
case of emergencies.
Refer to “Bulb Wattage” in chapter 8.
When changing lamps, first turn off
the engine at a safe place, firmly
apply the parking brake and detach
the battery’s negative (-) terminal.
Use only bulbs of the specifiedwattage. net-work failure
The headlamp, taillight, and fog light
may light up when the head lamp
switch is turned ON, and not light up
when the taillight or for light switch is
turned ON. This may be cause by net-
work failure or vehicle electrical control
system malfunction. If there is a prob-
lem, we recommend the system be
serviced by an authorized Kia dealer.
WARNING- Working on the lights
Prior to working on the lights,
firmly apply the parking brake,
ensure that the engine
start/stop button is in OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle that may cause burning
your fingers or receiving an
electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned- out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do notclean the headlamp lens withchemical solvents or strongdetergents.

APPEARANCE CARE
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.
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
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 mate-
rials. 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.
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.

Maintenance
Underbody maintenance
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame. The National Highway Traffic
Safety Administration has warned all
vehicle owners of all brands of the
need to take the following steps:
Wash the undercarriage of yourvehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.
Do a thorough washing of the undercarriage at the end of the
winter.
Use professional service techni- cians or governmental inspection
stations to annually inspect for cor-
rosion. Immediately seek an inspection of
your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Do not use any abrasive cleaner,polishing compound, solvent, or
wire brushes on aluminum wheels.
They may scratch the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral detergent, and rinse thoroughly with
water. Also, be sure to clean the
wheels after driving on salted roads.
This helps prevent corrosion.
Avoid washing the wheels with highspeed vehicle wash brushes.
Do not use any alkaline or acid detergents It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.

Corrosion protection
Protecting your vehicle from corrosion
By using advanced design and con-
struction practices to combat corro-
sion, we produce vehicles of excel-
lent 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 is
allowed 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 vehicle’s surface by
moisture that evaporates slowly.
Mud is particularly corrosive
because it dries slowly and holds
moisture in contact with the vehicle.
Although the mud appears to be dry,
it can still retain the moisture and
promote corrosion.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 forward
speed.

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
