7,500 miles (12,000 km). However, the timing
for tire rotation may vary according to your
driving habits and road surface conditions.
Wheel alignment and balance:If the vehicle
pulls to either side while driving on a straight and
level road, or if you detect uneven or abnormal
tire wear, there may be a need for wheel align-
ment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.

steep hill check that the vehicle is held securely
with the selector lever in the P (Park) position
without applying any brakes.Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel).
Windshield washer fluid*:Check that there is
adequate fluid in the tank.
Engine coolant level*:Check the coolant level
when the engine is cold.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, deterioration
or loose connections.
Brake fluid level*:Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Battery*:Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Engine drive belts*:Make sure that no belt isfrayed, worn, cracked or oily.
Engine oil level*:Check the level on the
dipstick after parking the vehicle on a level spot
and turning off the engine.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Exhaust system:Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately locate the trouble
and correct it. (See “Precautions when starting
and driving” in the “5. Starting and driving”
section for exhaust gas (carbon monoxide).)
Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the end
of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, see “Cleaning
exterior” in the “7. Appearance and care” sec-
tion.
Fluid leaks:Check under the vehicle for fuel,oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
