Maintenance7-10Owner MaintenanceOwner Maintenance ScheduleA qualified service technician should perform these
vehicle inspections at the indicated intervals to ensure
safe and dependable operation.
Bring any problem to the attention of an Authorized
Kia Dealer as soon as possible.
When refueling, check:
Engine oil level
Engine coolant level
Brake and clutch fluid level
Washer fluid level
CAUTION
Be careful when checking your engine coolant
level. The engine compartment will be hot and
you could be burned.
At least monthly:
Tire inflation pressures (cold)
Coolant level in reservoir (cold engine)
Every 6 months, check:
Power steering fluid level
Automatic transaxle fluid level
You can do the following scheduled maintenance items
if you have some mechanical ability, a few basic tools
and if you closely follow the directions in this manual.

Brakes and ClutchChecking Brake/Clutch Fluid LevelBrake Fluid Reservoir
Before 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.

NOTICE
In the event the brake/clutch system requires
frequent additions of fluid, the vehicle should be
inspected by an Authorized Kia Dealer.

Lubricant SpecificationsRecommended LubricantsTo help achieve proper engine and powertrain
performance and durability, use only lubricants of the
proper quality. The correct lubricants also help
promote engine efficiency which results in improved
fuel economy.Engine oils labeled Energy Conserving Oil are now
available. Along with other additional benefits, they
contribute to fuel economy 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.
These lubricants and fluids are recommended for use in your vehicle.
Lubricant Classification
Engine oil *1
API Service SJ, SL or above, ILSAC GF-3 or above
Manual transaxle oil API Service GL-4 (SAE 75W-85)
Automatic transaxle fluid SK ATF SP-III or DIAMOND ATF SP-III
Power steering fluid PSF-III
Brake/clutch fluid SAEJ1703 or FMVSS116 DOT-3 or DOT-4
*¹ Refer to the recommended SAE viscosity numbers on the next page.
