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
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 transmission occurs,
check the transmission fluid level.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after

At least monthly:
• Check the 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.
At least twice a year
(i.e., every Spring and Fall):
• Check the radiator, heater and air
conditioning hoses for leaks or
damage.
• Check the windshield washer spray
and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
• Check the headlight alignment.
• Check the muffler, exhaust pipes,
shields and clamps.
• Check the lap/shoulder belts for wear
and function.
At least once a year:
• Clean the body and door drain holes.
• Lubricate the door hinges and checks,
and hood hinges.
• Lubricate the door and hood locks and
latches.
• Lubricate the door rubber
weatherstrips.
