Maintenance
Automatic transaxle fluid
(if equipped)
Automatic transaxle fluid should not
be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
Kia dealer in accordance to the
scheduled maintenance at the begin-
ning of this chapter.
✽ ✽NOTICE
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker.
It is normal condition and you
should not judge the need to replace
the fluid based upon the changed
color.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake/clutch fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.

BRAKE/CLUTCH (IF EQUIPPED) FLUID
Checking the brake/clutch*
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake/clutch* fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch*
fluid contamination.
* if equipped If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage. This is a nor-
mal condition associated with the
wear of the brake linings and/or
clutch disc (if equipped). If the fluid
level is excessively low, have the
brake/clutch* system checked by an
authorized Kia dealer.
Use only the specified brake/clutch*
fluid. (Refer to “Recommended lubri-cants and capacities” in chapter 8.)
Never mix different types of fluid.
In the event the brake/clutch* system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding
brake/clutch* fluid, handle it carefully.
Do not let it come in contact with
your eyes. If brake/clutch* fluid
should come in contact with your
eyes, immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a doc-
tor as soon as possible.
Brake/clutch* fluid, which has been
exposed to open air for an extended
time should never be used as its
quality cannot be guaranteed. It
should be disposed of properly.
CAUTION - Brake/clutch fluid
Do not allow brake/clutch* fluidto contact the vehicle's bodypaint, as paint damage willresult.
CAUTION - Proper fluid
Only use brake/clutch fluid inbrake/clutch system. Smallamounts of improper fluids(such as engine oil) can causedamage to the brake/clutch sys-tem.

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) (if equipped) to
work irregularly.
✽ ✽
NOTICE
We recommend replacing tires with
the same make and model originally
supplied with the vehicle; not doing
so may affect driving performance.
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.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
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.Front lights replacement

(2) Headlight (Low)
(3) Front turn signal light
(4) Front fog light*
(5) Front position light*
(6) Side marker
* : if equipped
WARNING - 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.

Maintenance
Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
✽ ✽NOTICE
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body shop
applies anti-corrosion materials to
the parts repaired or replaced.
Bright-metal maintenance
To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright- metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
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, pol-ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral deter- gent, 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 high- speed car wash brushes.
Do not use any alkaline or acid deter- gent. It may damage and corrode the
aluminum wheels coated with a clear
protective finish.
