Disc brake pads should be inspected
for wear whenever tires are rotated.
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to left.
Do not use the compact spare tire for
tire rotation.Wheel alignment and tire bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
WARNING- Mixing tire
types
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics.

CAUTION - Wheel weight
Improper wheel weights can damage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.

Maintenance
Tire replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1.6 mm (1/16 inch) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.The ABS works by comparing the
speed of the wheels. Tire size can
affect wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.

Maintenance
LIGHT BULBS
Use only the bulbs of the specifiedwattage.
If you don’t have necessary tools, the
correct bulbs and the expertise, con-
sult an authorized Kia dealer. In
many cases, 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 if you have to remove
the headlight assembly to get to the
bulb(s). Removing/installing the
headlight assembly can result in
damage to the vehicle.Headlight, position light, turn
signal light, side marker light,
and front fog light bulb
replacementWARNING - Lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the “LOCK” position
and turn off the lights to avoid
burning your fingers or receiv-
ing an electric shock.
CAUTION - Light replacement
Be sure to replace the burned-out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.OTF074027N

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
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 fin-
ish. 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.
CAUTION - Headlight
Lens
To prevent damage, do not
clean headlight lens with chem-ical solvents or strong deter-gents.
