Tire rotation*Ð Tires should be rotated
every 7,500 miles (12,000 km).
Wheel alignment and balanceÐIfthe
vehicle should pull to either side while driv-
ing on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for a wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades*Ð Check for
cracks or wear if they do not wipe properly.
Doors and hoodÐ Check that all doors
and the hood operate properly. Also ensure
all latches lock securely. Lubricate hinges,
latches, rollers and links if necessary. Make
sure the secondary latch keeps the hood
from opening when the primary latch is
released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*Ð Make sure the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.INSIDE THE VEHICLE

lock securely in every position. Check that
the head restraints move up and downsmoothly and the locks (if so equipped) hold
securely in all latched positions.

belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.

smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.

operates smoothly and check that it has the
proper free travel.
BrakesÐ Check that the brakes do not pull
the vehicle to one side when applied.
Brake pedal*Ð Check the pedal for
smooth operation and make sure it has the
proper distance under it when depressed
fully. Check the brake booster function. Be
certain to keep the floor mat away from the
pedal.
