WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoring
system measures the vehicle's tire
pressures. A warning lamp
illuminates if one or more tires are
significantly underinflated or if there is a
system malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW WARNING: If the tire pressure
monitor sensor becomes damaged it may
not function. WARNING:
Under-inflation is the
most common cause of tire failures and
may result in severe tire cracking, tread
separation or blowout, with unexpected
loss of vehicle control and increased risk
of injury. Under-inflation increases sidewall
flexing and rolling resistance, resulting in heat buildup and internal damage to the
tire. It also may result in unnecessary tire
stress, irregular wear, loss of vehicle
control and accidents. A tire can lose up
to half of its air pressure and not appear
to be flat!
WARNING:
To determine the
required pressure(s) for your vehicle, see
the Safety Compliance Certification Label
(on the door hinge pillar, door-latch post
or the door edge that meets the door-latch
post, next to the driver seat) or the Tire
Label on the B-Pillar or the edge of the
driver door.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure
recommended by the vehicle manufacturer
on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires). As an added safety feature, your vehicle has
been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates a
low tire pressure telltale when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle
’s handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’ s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or
more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.

SYSTEM PRECAUTIONS WARNING: The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury. WARNING:
Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure to
follow this instruction could result in
personal injury or death.
Note: The use of tire sealants can damage
the tire pressure monitoring system.

TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS
When the outside temperature drops
significantly, the tire pressure could decrease
and activate the low tire pressure warning
lamp.
The warning lamp could also illuminate when
you use a spare wheel, or tire sealant from
the inflator kit.
Note:
Regularly checking the vehicle tire
pressures can reduce the possibility for the
warning lamp to illuminate due to outside
air temperature changes.
Note: After you inflate the tires to the
recommended pressure it could take up to
two minutes of driving over 20 mph (32 km/h)
for the warning indicator to turn off. VIEWING THE TIRE PRESSURES
Using the information display arrow keys
navigate to the truck info section where
you can view the tire pressures.
RESETTING TIRE PRESSURE
MONITORING SYSTEM

Note:
To reduce the chances of
interference from another vehicle,
perform the system reset procedure at
least three feet, one meter, away from
another vehicle undergoing the system
reset procedure at the same time.
Note: Do not wait more than two
minutes between resetting each tire
sensor or the system can time-out and
you need to repeat the entire procedure
on all four wheels.
1. Drive the vehicle above 20 mph
(32 km/h) for at least two minutes,
then park in a safe location where
you can easily get to all four tires and
have access to an air pump.
2. Switch the ignition off.
3. Switch the ignition on but do not start
the engine.
4. Switch the hazard flashers on then off three times. Note:
You must accomplish this within
10 seconds. If you successfully enter the
reset mode, the horn sounds once, the
system indicator flashes and a message
shows in the information display.
Note: If the system does not enter reset
mode, try again starting at Step 2. If
after repeated attempts to enter the
reset mode, the horn does not sound,
the system indicator does not flash and
no message shows in the information
display, contact your authorized dealer.
5. Remove the valve cap from the valve
stem on the left front tire. Decrease
the air pressure until the horn
sounds.
Note: The single horn tone confirms that
the sensor identification code has been
learned by the module for this position.
If the horn sounds twice, the reset
procedure was unsuccessful, and you
must repeat it.
6. Remove the valve cap from the valve
stem on the right front tire. Decrease
the air pressure until the horn
sounds. 7.
Repeat the previous step on the right
rear tire and then on the left rear tire.
8. Switch the ignition off.
Note: If the horn sounds twice again
after switching the ignition off, and
repeating the procedure, contact your
authorized dealer and have your vehicle
checked as soon as possible.
9. Set all four tires to the recommended
air pressure as indicated on the
Safety Compliance Certification
Label.

Monitoring System – Information Messages
(page 459). Tire pressure
sensors are mounted into each tire on
your trailer. The sensors send a
message to your vehicle indicating the
current trailer tire pressure and
temperature.
If the trailer tire pressure monitoring
system detects that a tire is low, a
warning message appears in the
information display. The trailer tire
information screen in the information
display highlights the tire with a low
pressure.
If the trailer tire pressure monitoring
system detects that a tire temperature
is over temp, a warning message
appears in the Information display. The
trailer tire information screen in the
information display highlights the tire
with a high temperature. The main function of the trailer tire
pressure monitoring system is to warn
you when your trailer tires need air or if
the tires are experiencing high
temperatures. It can also warn you in the
event the system is no longer capable
of functioning as intended.
See Tire
Pressure Monitoring System –
Information Messages
(page 459).
When a Temporary Spare or New Tire
is Installed
