OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized 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 deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
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 steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
Check the automatic transaxle P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING- Hot coolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure.
WARNING
When you open the engine
hood, turn the Hybrid system
off. If not, it may result in death
or serious injury because of the
high voltage flow.
