The Tire Pressure Monitoring System
does not alleviate the need to check the
tire condition every day, including
whether the tires all look inflated properly.
Inspect all tire pressure monthly
(including the spare) when the tires are
cold. Maintain recommended pressures
for the best ride, handling, and minimum
tire wear.
When checking the tire pressures, use of a
digital tire pressure gauge is
recommended.
Except Canada (Tire pressure label)
Canada (Motor vehicle safety standard
label)
Refer to the specification charts (page
10-6).

NOTE
Always check tire pressure when tires are
l
cold.
Warm tires normally exceed recommended
l
pressures. Don't release air from warm tires
to adjust the pressure.
Underinflation can cause reduced fuel
l
economy, uneven and accelerated tire wear,
and poor sealing of the tire bead, which
will deform the wheel and cause separation
of tire from rim.
Overinflation can produce a harsh ride,
l
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
qTire Rotation
To equalize tread wear, rotate the tires if
irregular wear develops. According to the
scheduled maintenance charts.Refer to
Scheduled Maintenance on page 8-3.
During rotation, inspect them for correct
balance.
Forward
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
Incorrect tire pressure
l
Maintenance and Care
Owner Maintenance
