The TRAC OFF light may come on for the
following reasons:
If you turn the system off by pressing the TCS on/off
button located to the right of the steering wheel, the
light will come on and stay on. To turn the system
back on, press the button again; the light should
go off.
If you move the shift lever to FIRST (1), the light
will come on and stay on to indicate that the Traction
Control System is off. This is normal operation.
To turn the system back on, move the shift lever
back to a position other than FIRST (1); the light
should go off. See ªTraction Control Systemº in
the Index.
The light will come on and stay on if the TCS
automatic engagement feature has been turned off.
To turn the system on, press the TCS off/on button;
the light should go off. To turn the automatic
engagement feature back on, see ªTraction Control
Systemº in the Index.
If the Traction Control System is affected by an
anti
-lock brake system, Traction Control System or
engine
-related problem, the system will turn off and
the light will come on. Have your vehicle serviced.If the vehicle is driven over an extremely rough road,
the system will turn off and the light will come on.
The light will go off a few seconds after the rough
road conditions go away or when the vehicle comes
to a complete stop. This is normal operation.

2-90 STABILITY SYSTEM ACTIVE Message
You may see the
STABILITY SYSTEM
ACTIVE message on
the message center.
It means that an advanced computer
-controlled system
has come on to help your vehicle continue to go in
the direction in which you're steering. This stability
enhancement system activates when the computer senses
that your vehicle is just starting to spin, as it might if
you hit a patch of ice or other slippery spot on the road.
It also activates when it senses that your wheels are
spinning, as they might when accelerating on a road
surface that provides inadequate traction. When the
system is on, you may hear a noise or feel a vibration in
the brake pedal. This is normal. When the STABILITY
SYSTEM ACTIVE message is on, you should continue
to steer in the direction you want to go. The system is
designed to help you in bad weather or other difficult
driving situations by making the most of whatever road
conditions will permit.
STABILITY SYSTEM LIMITED Message
The STABILITY SYSTEM
LIMITED message will
turn on when you press
the Stabilitrak button;
see ªInstrument Panelº
in the Index.
While in ªLIMITEDº mode, traction control is disabled
and the stability system is less likely to activate. To limit
wheel spin and realize the full benefits of the stability
enhancement system, you should normally leave
Stabilitrak in its normal operating mode (not the
LIMITED mode). However, you should put Stabilitrak
in LIMITED mode if your vehicle gets stuck in sand,
mud, ice or snow and you want to ªrockº your vehicle to
attempt to free it. See ªRocking Your Vehicleº in the
Index. To exit the LIMITED mode, press the Stabilitrak
button again. The STABILITY SYSTEM LIMITED
message will be displayed whenever the transmission is
in FIRST (1). Traction control will not operate in this
gear. This is normal.

Remember: Anti-lock doesn't change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won't have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal down
firmly and let anti
-lock work for you. You may feel the
brakes vibrate, or you may notice some noise, but this
is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System (TCS)
(2
-Wheel Drive)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens, the
system reduces engine power to limit wheel spin.
This light will come on
when the TCS is limiting
wheel spin. See ªLow
Traction Lightº in the
Index. You may hear or
feel the system working or
notice a lack of accelerator
response, but this is normal.
The Traction Control System may operate on dry roads
under some conditions. When this happens, you may
notice a reduction in acceleration. This is normal and
doesn't mean there's a problem with your vehicle.
Examples of these conditions include a hard acceleration
in a turn, an abrupt upshift or downshift of the
transmission or driving on rough roads.

If your vehicle is in cruise control when the TCS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re
-engage the cruise control.
See ªCruise Controlº in the Index.
When the TRAC OFF
light is on, the TCS is
off and will not limit
wheel spin. Adjust your
driving accordingly.
The TRAC OFF light will come on under the
following conditions:
The Traction Control System is turned off, either by
pressing the TCS on/off button or turning off the
automatic engagement feature of the TCS.
The transmission is in FIRST (1); TCS will not
operate in this gear. This is normal.The vehicle is driven on an extremely rough road.
When the vehicle leaves the rough surface, slows
down or stops, the light will go off and TCS will be
on again. This is normal.
A Traction Control System, Anti
-Lock Brake
System or engine
-related problem has been detected
and the vehicle needs service.
See ªTraction Off Lightº in the Index.
The Traction Control System, as delivered from the
factory, will automatically come on whenever you start
your vehicle. To limit wheel spin, especially in slippery
road conditions, you should always leave the system on.
But you can turn the TCS off if you ever need to.
You should turn the TCS off if your vehicle ever gets
stuck in sand, mud or snow and rocking the vehicle is
required. See ªRocking Your Vehicleº in the Index.
To turn the system on or
off press the TCS on/off
button located to the right
of the steering wheel,
on the instrument panel.
