The STABILITY SYS ACTIVE message will appear on
the Driver Information Center (DIC) only when the
system is both on and activated. You may also feel or
hear the system working; this is normal. For more
information on the stability messages, see Driver
Information Center (DIC) on page 3-58.
The Stabilitrak
®
mode
button is located on the
instrument panel.
Stabilitrak
®
and part of the traction control system can
be turned off or back on by pressing the
Stabilitrak
®
button. All-wheel drive vehicles must be in
all-wheel drive mode to turn the system on or off.
When the system is turned off, the traction off light will
illuminate, and the STABILITY SYS DISABLED
message will appear on the DIC to warn the driver that
both the stability system and part of the traction
control system are disabled. Your vehicle will still have
brake-traction control when Stabilitrak
®
is off, but
will not be able to use the engine speed management
system. See “Traction Control Operation” next for
more information.
When the Stabilitrak
®
system has been turned off you
may still hear system noises as a result of the
brake-traction control coming on.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if your vehicle is stuck in sand, mud, ice
or snow, and you want to “rock” your vehicle to
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. See If You Are
Stuck: In Sand, Mud, Ice or Snow on page 4-50.
When the transfer case is in 4 low, the stability system
is automatically disabled, and the STABILITY SYS
DISABLED message will appear on the DIC. In 4LO,
the Stabilitrak
®
button only turns the traction control
system on and off.
Traction Control Operation
The traction control system is part of the
Stabilitrak
®
system. Traction control limits wheel spin by
reducing engine power to the wheels (engine speed
management) and by applying brakes to each individual
wheel (brake-traction control) as necessary.
