OWNER MAINTENANCE Owner maintenance schedule The following lists are vehicle checks and
inspections that should be performed by
the owner or an Authorized Kia Dealer at
the frequencies indicated to help ensure
safe, dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.
When you stop for fuel: Check the engine oil level.
Check coolant level in coolant reser-voir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle: Note any changes in the sound of the exhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling on smooth, level road.
When stopping, listen and check for strange sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
If any slipping or changes in the oper- ation of your transmission occurs,
check the transmission fluid level.
Check automatic transmission P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns or
other serious injury.

Maintenance87At least monthly: Check coolant level in the coolantrecovery reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tires including the spare.
At least twice a year (i.e., every Spring and Fall) : Check radiator, heater and air condi- tioning hoses for leaks or damage.
Check windshield washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
Check headlight alignment.
Check muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.
At least once a year : Clean body and door drain holes.
Lubricate door hinges and checks, andhood hinges.
Lubricate door and hood locks and latches.
Lubricate door rubber weatherstrips.
Check the air conditioning system before the warm weather season.
Check the power steering fluid level.
Inspect and lubricate automatic trans- mission linkage and controls.
Clean battery and terminals.
Check the brake fluid level.

Maintenance
POWER STEERING Checking the power steering fluid
level With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the reservoir at the normal tem-
perature.
Before adding power steering fluid, thor-
oughly clean the area around the reser-
voir cap to prevent power steering fluid
contamination.
If the level is low, add fluid to the MAX
level.In the event the power steering system
requires frequent addition of fluid, the
vehicle should be inspected by an
Authorized Kia Dealer.
Use only the specified power steering
fluid. (Refer to "RecommendedLubricants" later in this section.)
Power steering hoseCheck the connections for oil leaks,
severe damage and the twists in the
power steering hose before driving.
OBL056007
CAUTION
To avoid damage to the power steering pump, do not operate thevehicle for prolonged periodswith a low power steering fluid level.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the tank.
Too little fluid can make the steer- ing wheel heavier or strangenoise can be generated.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering wheel and cause damage to it.

TIRES AND WHEELS
Tires care For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.Inflation pressures All tire pressures (including the
spare) should be checked every day
when the tires are cold. “Cold Tires”
means the vehicle has not been driv-
en for at least three hours or driven
less than 1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
(Refer to “Tires” in section 8,
Specifications.) All specifications (sizes and pres-
sures) can be found on a label
attached to the front driver’s door sill.
WARNING
- Tire underin-
flation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for protracted periods at high
speeds.

WARNING
- Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and lead
to sudden tire failure. This could
result in loss of vehicle control
and potential injury.
CAUTION
- Tire pressure
Always observe the following: Check tire pressure when the tires are cold. (After vehiclehas been parked for at leastthree hours or hasn't beendriven more than 1.6 km (onemile) since startup.)
Check the pressure of your spare tire each time you checkthe pressure of other tires.
Never overload your vehicle. Be careful not to overload avehicle luggage rack if yourvehicle is equipped with one.
Worn, old tires can cause acci- dents. If your tread is badlyworn, or if your tires havebeen damaged, replace them.
CAUTION
Underinflation also results in excessive wear, poor handlingand reduced fuel economy.Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If atire frequently needs refilling,have it checked by anAuthorized Kia Dealer.
Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
CAUTION
Warm tires normally exceed recommended cold tire pres-sures by 28 to 41 kPa (4 to 6psi). Do not release air fromwarm tires to adjust the pres-sure or the tires will be under-inflated.
Be sure to reinstall the tire inflation valve caps. Withoutthe valve cap, dirt or moisturecould get into the valve coreand cause air leakage. If thecap have been lost, install newone as soon as possible.

727
Maintenance
Checking tire inflation pres-
sureCheck your tires once a month or
more.
Also, check the tire pressure of the
spare tire.How to checkUse a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.
Tire rotation To equalize tread wear, it is recom-
mended that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire
also if you can see fabric or cord.
After rotation, be sure to bring the
front and rear tire pressures to spec-
ification and check lug nut tightness.
Refer to Section 8, Specifications.

Maintenance
Wheel alignment and tire
balance 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 -
Replacing
tires
Driving on worn-out tires is very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.
Your vehicle is equipped with tires designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tire and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tires, be sure to equip all
four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capacity.
(Continued)
(Continued)If you nevertheless decide to
equip your vehicle with any
tire/wheel combination not
recommended by Kia for off
road driving, you should not
use these tires for highway
driving.
The use of any other tire size or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tire clearance, snow tire
clearance, and speedometer
reliability.
It is best to replace all four tires at the same time. If that is
not possible, or necessary,
then replace the two front or
two rear tires as a pair.
Replacing just one tire can
seriously affect your vehicle’s
handling.
CAUTION
Improper wheel weights candamage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.

7Wheel replacement When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire sidewall labelingFederal law requires tire manufactur-
ers to place standardized information
on the sidewall of all tires. This infor-
mation identifies and describes the
fundamental characteristics of the
tire and also provides the tire identifi-
cation number (TIN) for safety stan-
dard certification. The TIN can be
used to identify the tire in case of a
recall.
1. Manufacturer or brand nameManufacturer or Brand name is
shown.2. Tire size designation A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer calibration, head-
light aim and bumper height.
