the fuel economy mode. The vehicle is safe to drive,
however you should have the electrical system checked
by your dealer/retailer.

StabiliTrak Off
In this mode, both stability control and part of the traction
control system are disabled. The vehicle will still have
brake-traction control, but will not be able to use the
engine speed management system. System noises may
be heard as a result of the brake-traction control coming
on. If the controller detects excessive wheel spin in this
mode, the StabiliTrak indicator light may blink and the
STABILITRAK ACTIVE message may be displayed
to warn the driver that damage may occur to the
transfer case.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if the vehicle is stuck in sand, mud, ice orsnow, and you may want to “rock” the vehicle in an
attempt to free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions
where high wheel spin is required. SeeIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 4-30
for more information.
When the transfer case is in 4LO, the stability system is
automatically disabled. The StabiliTrak light will come
on and the STABILITRAK OFF message will appear on
the DIC. The StabiliTrak system cannot be turned on
until the vehicle is switched to 2HI, 4HI, or 4AWD.
The following chart describes the StabiliTrak system
events and the corresponding messages and lights that
will be displayed on the instrument panel cluster.

The Tire Pressure Monitor System (TPMS) operates
on a radio frequency and complies with Part 15 of
the FCC Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
The TPMS operates on a radio frequency and complies
with RSS-210 of Industry and Science Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver
when a low tire pressure condition exists. TPMS sensors
are mounted onto each tire and wheel assembly,
excluding the spare tire and wheel assembly, if the
vehicle has one. The TPMS sensors monitor the
air pressure in the vehicle’s tires and transmit the tire
pressure readings to a receiver located in the vehicle.
The TPMS is designed to alert the driver if a low
tire pressure condition exists. If your vehicle has the
Driver Information Center (DIC) steering wheel control
buttons, tire pressure levels may also be checked
through the DIC. See “Tire Pressures” underDIC
Operation and Displays on page 3-48.
When a low tire pressure
condition is detected, the
TPMS illuminates the low
tire pressure warning light
located on the instrument
panel cluster.
