Vehicle Care 371TPMS Malfunction Light and
Message The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message also displays. The
malfunction light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause these to come on are:
.
One of the road tires has been
replaced with the spare tire. The
spare tire does not have a
TPMS sensor. The malfunction
light and the DIC message
should go off after the road tire
is replaced and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section. .
The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message should go off after
successfully completing the
sensor matching process. See
"TPMS Sensor Matching
Process" later in this section.
.
One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully. See
your dealer for service.
.
Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. See Buying
New Tires 0 378 . .
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire pressure condition. See
your dealer for service if the TPMS
malfunction light and DIC message
come on and stay on.
Tire Fill Alert (If Equipped) This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure.
When the low tire pressure warning
light comes on:
1. Park the vehicle in a safe, level
place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is
underinflated. The turn signal
lamp will flash.

and Loading Information label.
Trailer Tire Pressure
Monitoring Operation If equipped, the Trailer Tire
Pressure Monitoring System
(TTPMS) is designed to monitor the
pressure of the trailer tires and warn
the driver when a low pressure
condition exists. TTPMS sensors for
four tires are provided. The system
can accommodate a trailer with up
to six tires if additional sensors are
purchased from the dealer. Also, the
system can be paired with up to five
individual trailers. Prior to use, the vehicle must learn
the sensors by following the
learning process. See Trailering App
0 296 .
Contact your trailer service center or
tire service center to have the
pressure sensors installed inside
the trailer tires. The technician
should insert the sensor stem
through the hole in the trailer wheel.
When the sensor is correctly
positioned, the nut on the sensor
stem should be tightened to 8 Y
(6 lb ft). When mounting the trailer
tire onto the trailer wheel be careful
not to damage the sensor. The Trailering App can be used to
view the tire pressures after the
recommended trailer tire pressures
have been entered. Refer to the
trailer tire placard on the trailer or
the trailer tire sidewall for the
recommended tire pressure.
The system is compatible with trailer
tires that have placard pressure
values from 103 - 689 kpa (15 -
100 psi). The hole in the wheel for
the tire stem must be 11.43 mm
(0.453 in) in diameter. Use of the
pressure sensors on a wheel with a
different stem hole size could result
in loss of air from the tire.
If a low trailer tire pressure condition
is detected, the TTPMS displays a
warning message on the DIC. If the
warning message is displayed, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the tire placard on the
trailer.
In addition, the TTPMS monitors the
temperature of the trailer tires. If the
system detects a high temperature
on one or more of the trailer tires, a
warning message will be displayed

Mexico-1500-11698638) - 2019 - crc - 5/15/18
Vehicle Care 375on the DIC. If this warning message
is displayed, stop as soon as
possible, and inspect the
overheated trailer tire. Common
causes for high trailer tire
temperature are underinflation,
overloading, or tire damage.
TTPMS Malfunction Message The TTPMS will not function
properly if one or more of the trailer
tire sensors are missing or
inoperable. If the system detects a
malfunction, a DIC message
indicates that the system requires
service. Some of the conditions that
can cause the service message to
occur are:
.
One of the trailer tires has been
replaced with the spare tire
which does not have a learned
TTPMS sensor. The DIC
message should turn off after the
pressure sensor is installed in
the tire, and the learning process
is performed successfully. See
"TTPMS Sensor Learning
Process" under Trailering App
0 296 . .
The TTPMS sensor learning
process was not done or not
completed successfully. The DIC
message should go off after
successfully completing the
sensor learning process. See
"TTPMS Sensor Learning
Process" under Trailering App
0 296 .
.
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 0 296 .
.
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.

410 Vehicle Care 2. Remove excess moisture by
gently wringing until water does
not drip from the cleaning cloth.
3. Start on the outside edge of the
soil and gently rub toward the
center. Fold the cleaning cloth
to a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the
soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely
removed, use a mild soap
solution followed only by plain
water.
If the soil is not completely
removed, it may be necessary to
use a commercial upholstery
cleaner or spot lifter. Test a small
hidden area for colorfastness before
using a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the entire
fabric or carpet.
After cleaning use a paper towel to
blot excess moisture. Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays Use a microfiber cloth on high gloss
surfaces or vehicle displays. First,
use a soft bristle brush to remove
dirt that can scratch the surface.
Then gently clean by rubbing with a
microfiber cloth. Never use window
cleaners or solvents. Periodically
hand wash the microfiber cloth
separately, using mild soap. Do not
use bleach or fabric softener. Rinse
thoroughly and air dry before
next use.
CautionDo not attach a device with a
suction cup to the display. This
may cause damage and would
not be covered by the vehicle
warranty. Instrument Panel, Leather,
Vinyl, Other Plastic Surfaces,
Low Gloss Paint Surfaces and
Natural Open Pore Wood
Surfaces Use a soft microfiber cloth
dampened with water to remove
dust and loose dirt. For a more
thorough cleaning, use a soft
microfiber cloth dampened with a
mild soap solution.
CautionSoaking or saturating leather,
especially perforated leather, as
well as other interior surfaces,
may cause permanent damage.
Wipe excess moisture from these
surfaces after cleaning and allow
them to dry naturally. Never use
