successfully completing the
sensor learning process. See
"TTPMS Sensor Learning
Process" under

.
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
.
.
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
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
unusual wear continues after the
rotation, check the wheel
alignment. See
