One or more TTPMS sensors are missing
or damaged. The DIC message should go
off when the TTPMS sensors are installed
and the sensor learning process is
performed successfully. See "TTPMS
Sensor Learning Process" under Trailering
App 0 283.
Operating electronic devices or being near
facilities using radio wave frequencies
similar to the TTPMS could cause
interference to the TTPMS which could
cause loss of signal reception from the
sensor.
If the system does not receive the signal
from an individual sensor, an error
message may not occur until the vehicle
has been driver for a period of time.
If the TTPMS is not functioning properly, it
cannot detect or signal a low tire condition.
See your dealer for service if the DIC
message comes on and stays on when the
trailer tire pressures have been checked and
determined to be correct.

Tire Inspection

We recommend that the tires, including
the spare tire, if the vehicle has one, be
inspected for signs of wear or damage
at least once a month.
Replace the tire if:
The indicators at three or more
places around the tire can be seen.
There is cord or fabric showing
through the tire's rubber.
The tread or sidewall is cracked, cut,
or snagged deep enough to show
cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other
damage that cannot be repaired well
because of the size or location of the
damage.

Tire Rotation

Tires should be rotated every 12 000 km
(7,500 mi). See Maintenance Schedule
0 362.
Tires are rotated to achieve a more
uniform wear for all tires. The first
rotation is the most important.
Anytime unusual wear is noticed, rotate
the tires as soon as possible, check for
proper tire inflation pressure, and check
for damaged tires or wheels. If the
Vehicle Care
unusual wear continues after the
rotation, check the wheel alignment.
See When It Is Time for New Tires
0 330 and
Wheel Replacement 0 333.
Use this rotation pattern when rotating
the tires.
Adjust the front and rear tires to the
recommended inflation pressure on the
Tire and Loading Information label after
the tires have been rotated. See Tire
Pressure 0 322 and
Vehicle Load Limits 0 179.
