When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights* Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts* When checking the tires,
make sure no wheel nuts are missing, and check
for any loose wheel nuts. Tighten if necessary.
Tire rotation* Tires should be rotated every
7,500 miles (12,000 km).
Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components Replace the grom-
met seal, valve core and cap of the transmitter in
vehicles equipped with TPMS at every tire re-
placement or when reaching the wear limit of the
tires.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, theremay be a need forwheel
alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
