BRAKES AND CLUTCHCHECKING BRAKE/CLUTCH
FLUID LEVELBrake Fluid ReservoirBefore adding fluid, thoroughly clean the
area around the reservoir cap to prevent
brake fluid contamination.
If you add brake/clutch fluid, fill the
brake/clutch fluid reservoir to the MAX
line. The brake/clutch fluid level will
drop with accumulated mileage. This is a
normal condition associated with
brake/clutch lining wear.Check the fluid level in the reservoir
periodically; it should be between MAX
and MIN on the side of the reservoir.
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 Lubricants
later in this section.)
Do not mix different types of fluid.

MAINTENANCE
7-18PARKING BRAKECHECKING THE PARKING BRAKECheck the stroke of the parking brake by
counting the number of “clicks” heard
while fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a
fairly steep grade.
If the number of “clicks” is more or less
than specified, have the parking brake
adjusted by an Authorized Kia Dealer.
Stroke:
5-9 “clicks” at a force of 22 lbs. (98N).
POWER STEERINGCHECKING THE POWER
STEERING FLUID LEVELThe power steering fluid level should be
checked periodically. With the engine
off and the vehicle on level ground,
check the fluid level in the power
steering reservoir; it should be between
the MAX and MIN reservoir indicators.Before adding power steering fluid,
thoroughly clean the area around the
reservoir 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 “Recommended Lubricants”
later in this section.)

NOTICE
To avoid damage to the power
steering pump, do not operate the
vehicle for prolonged periods with
low power steering fluid level.

AUTOMATIC TRANSAXLECHECKING THE
AUTOMATIC TRANSAXLE
FLUID LEVELThe automatic transaxle fluid level
should be checked regularly. Take the
following precautions to measure the
fluid level properly.The volume of the transaxle fluid changes
with temperature. For that reason, it is
best to check the level after having driven
the vehicle for 30 minutes. If necessary,
however, the fluid can also be checked
when the vehicle has not been driven.
1. Park the vehicle on level ground and
set the parking brake firmly.
2. Allow the engine to idle for about 2
minutes, then depress the brake
pedal. Move the shift lever slowly
through all ranges then set it in the P
(Park) position.
3. With the engine still idling, pull the
dipstick out, wipe it clean, and
reinsert it fully.
4. Pull the dipstick out again.
The fluid level is checked as follows:
MMSA7010
CAUTION
• Low fluid level causes transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and
transaxle malfunction.
• The use of a non-specified fluid
could result in transaxle
malfunction and failure.
WARNING - Parking
Brake
To avoid sudden movement of
the vehicle, set the parking
brake and depress the brake
pedal while shifting the shift
lever.

TIRE ROTATIONTo equalize tread wear, it is
recommended that the tires be rotated
every 12,000km (7,500 miles) or sooner
if irregular wear develops.
During tire rotation, check the tires for
correct balance.
Check for uneven wear and damage.
Abnormal wear is usually caused by
incorrect tire pressure, improper wheel
alignment, an out-of-balance condition,
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. Also, replace
the tire if you can see fabric or cord.
After rotation, be sure to bring the front
and rear tire pressures to specification
and check lug nut tightness.
Disc brake pads should be inspected for
wear whenever tires are rotated.
TIRE REPLACEMENTIf the tire is worn evenly, a tread wear
indicator will appear as a solid band,
12.7mm wide (1/2 inch) across the
tread. This shows there is less than
1.6mm (1/16 inch) of tread remaining on
the tire. Replace the tire when this
happens.
Do not wait for this band to appear
across the entire tread before replacing
the tire.

NOTICE
Rotate radial tires that have an
asymmetric tread pattern from
front to rear only and not from
right to left.

RECOMMENDED SAE
VISCOSITY NUMBEREngine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operation (starting and oil flow). Lower
viscosity engine oils can provide better fuel
economy and cold weather performance,
however, higher viscosity engine oils are
required for satisfactory lubrication in hot
weather. Using oils of any viscosity other
than those recommended could result in
engine damage.
These lubricants and fluids are recommended for use in your vehicle.*1)
Refer to the recommended SAE viscosity numbers on the this page.
* Recommended for the Canadian climate.
Lubricant Classification
Engine oil* API Service SJ, SL or above,
ILSAC GF-3 or above
Manual transaxle oil* API Service GL-4 (SAE 75W-85)
Automatic trasaxle fluid SK ATF SP-III or Diamond ATF SP-III
Power steering fluid PSF-IV
Brake/clutch fluid SAEJ1703 or FMVSS116 DOT-3 DOT-4
✻
NOTICE
Always be sure to clean the area
around any filler plug, drain plug,
or dipstick before checking or
draining any lubricant. This is
especially important in dusty or
sandy areas and when the vehicle is
used on unpaved roads. Cleaning
the plug and dipstick areas will
prevent dirt and grit from entering
the engine and other mechanisms
that could be damaged.

of temperature your vehicle will be
operated in before the next oil change.
Then select the recommended oil
viscosity from the chart.EXTERIOR CAREEXTERIOR GENERAL
CAUTIONIt is very important to follow the
manufacturer’s directions when using
any chemical cleaner or polish. Read all
warning and caution statements that
appear on the label.FINISH MAINTENANCE
WASHINGTo help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
special attention to the removal of any
accumulation of salt, dirt, mud, or other
foreign materials. Make sure the drainholes in the lower edges of the doors and
rocker panels are kept clear and clean.
Insects, tar, tree sap, bird droppings,
industrial fallout 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, can be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
WAXINGWax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim as well,
to protect it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.
✻
NOTICE
Do not use strong soap, chemical
detergents or hot water, and do not
wash the vehicle in direct sunlight
or when the body of the vehicle is
warm.
CAUTION
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
7-40ALUMINUM WHEEL
MAINTENANCEThe 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 or damage the finish.
• 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 high-
speed car wash brushes.
