MAINTENANCE AND LUBRICATION 201
CAUTION
Never bleed air from your tires in an attempt to gain traction for a vehicle stuck
in snow, ice or mud. This practice provides no additional traction and typically
results in underinflated tires. Never bleed air from a hot tire since that tire will
then be underinflated.
To adjust for pressure fluctuations induced by temperature changes associated
with winter weather, it is recommended that tire inflation pressure be checked
daily when the tires are cold (i.e., before the vehicle is driven). Always use an
accurate tire pressure gauge.
Inspection
Inspect your tires daily. Look for bulges, cracks, cuts, penetrations and/or
oil contamination. If any such damage is found, the tire must be thoroughly
inspected by a qualified tire inspector and repaired or discarded immediately,
at his discretion. Also, check for uneven wear. If found, a thorough inspection
of front end parts and alignment should be made by a qualified mechanic.
Refer to the Maintenance and Lubrication Manual (21394653) for more
information.
