Maintenance
Owner maintenance schedule
When you stop for fuel:
•Check the engine oil level.
•Check coolant level in the engine
coolant reservoir.
•Check the windshield washer fluid
level.
•Check 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 if there is any
increased steering effort or loose-
ness in the steering 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 vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).
At least monthly:
•Check coolant level in the engine
coolant reservoir.
•Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
•Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
•Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
