Trailer Tire Pressure Monitoring
System (If Equipped)
Note: Additional equipment may be
required for your vehicle to support trailer
tire pressure monitoring. See your authorized
dealer for more information.
Note: The trailer tire pressure monitoring
system is not a substitute for proper tire
maintenance. It is your responsibility to
maintain correct tire pressures at all times.
Note: If a trailer tire is repaired, replaced or
broken down for service, the screw and valve
on the trailer tire pressure sensor should be
replaced. See your authorized dealer for
details. The trailer tire pressure monitoring system
is an added safety feature that allows you
to view your trailer tire pressures through
the information display.
See General
Information (page 110). 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.
If the trailer tire pressure monitoring
system detects that a tire is low, a warning
message appears in the information
display. The trailer tire pressure status
screen in the information display highlights
the tire with a low pressure.
The main function of the trailer tire
pressure monitoring system is to warn you
when your trailer tires need air. It can also
warn you in the event the system is no
longer capable of functioning as intended.
See
Information Messages (page 121).
When a Temporary Spare or New Tire
is Installed
If you have replaced a trailer tire with a new
or spare tire, a warning message appears
and pressure readings are no longer
displayed for that tire.
To restore the full function of the trailer
tire pressure monitoring system:
• Have the damaged wheel and tire
assembly repaired and remounted to
your trailer.
• Install the trailer tire pressure
monitoring sensor into the new wheel
and tire assembly.
• Perform the trailer tire pressure
monitoring system reset procedure.
Trailer Tire Pressure Monitoring
System Reset Procedure
Note: You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation, or when a new trailer tire
pressure sensor is installed into a trailer tire.

The trailer tire pressure monitoring system
can be reset through the menu in the
information display. See General
Information (page 110). Performing the
trailer setup process also resets the trailer
tire pressure monitoring system.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: If your vehicle is equipped with the
tire pressure monitoring system, the
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
If your vehicle is equipped with the tire
pressure monitoring system, have a flat
serviced by an authorized dealer in order
to prevent damage to the system sensors.
See
Tire Pressure Monitoring System
(page 421). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the system
sensor for damage. Dissimilar Spare Wheel and Tire

WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel
hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)
