If there is a problem with
ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light on
page 3-57.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps receiving
updates on wheel speed and controls braking pressure
accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. The antilock pump or
motor operating might be heard and the brake pedal
might be felt to pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more than
even the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle speed
in emergency driving conditions. This feature uses the
stability system hydraulic brake control module to
supplement the power brake system under conditions
where the driver has quickly and forcefully applied
the brake pedal in an attempt to quickly stop or slow
down the vehicle. The stability system hydraulic
brake control module increases brake pressure at each
corner of the vehicle until the ABS activates. Minor
brake pedal pulsations or pedal movement during this
time is normal and the driver should continue to
apply the brake pedal as the driving situation dictates
The Brake Assist feature will automatically disengage
when the brake pedal is released or brake pedal
pressure is quickly decreased.
4-5

StabiliTrak®System
The vehicle may have the StabiliTrak system which
combines antilock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes and reducing engine power.
The StabiliTrak system comes on automatically
whenever the vehicle is started. The system cannot be
turned off.
This light will ash when
the system is operating.
The STABILITRAK NOT READY message may be
displayed in the Driver Information Center (DIC) and the
Traction Control System (TCS)/StabiliTrak warning
light on the instrument panel cluster comes on after rst
driving the vehicle and exceeding 19 mph (30 km/h)
for 30 seconds. The StabiliTrak system is off until the
light has turned off. This could take up to 15 minutes.The TCS/StabiliTrak warning light on the instrument
panel cluster will ash when the system is operating.
SeeTraction Control System (TCS) Warning Light
on page 3-58andStabiliTrak®Indicator Light on
page 3-58for more information. The system may be
heard or felt while it is working. This is normal.
The SERVICE STABILITRAK message is displayed and
the TCS/StabiliTrak warning light on the instrument panel
cluster comes on if there is a problem with the system.
When this light and the SERVICE STABILITRAK
message are on, the system is not working. Adjust your
driving accordingly.
Traction Control System (TCS)
The vehicle has 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 the front wheels are spinning too much or beginning
to lose traction. When this happens, the system works
the front brakes and reduces engine power (by closing
the throttle and managing engine spark) to limit
wheel spin.
4-6

The TCS and StabiliTrak®
light will ash when the
system is limiting
wheel spin.
The system may be heard or felt while it is working, but
this is normal. SeeTraction Control System (TCS)
Warning Light on page 3-58for more information.
If the vehicle is in cruise control when TCS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control may be re-engaged when
road conditions allow. SeeCruise Control on page 3-16.
The SERVICE TRACTION CONTROL message in
the DIC and the TCS/StabiliTrak warning light comes on
if there is a problem with the traction control system.
SeeDIC Warnings and Messages on page 3-73.
When this light and the SERVICE TRACTION
CONTROL message are on, the system will not limit
wheel spin. Adjust your driving accordingly.To turn the system off or
on, press and release this
button located in front
of the shift lever.
TCS automatically comes on whenever the vehicle is
started. To limit wheel spin, especially in slippery
road conditions, always leave the system turned on.
TCS can be turned off if needed.
The system can be turned on or off at any time by
pressing the TCS button. The DIC will display
TRACTION CONTROL OFF when the button is pressed,
and part of the traction control system is 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 working. If the controller detects
excessive wheel spin in this mode, the TCS/StabiliTrak
light may blink.
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 or
snow, and you want to “rock” the vehicle to attempt to
free it. SeeIf Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-18.

Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
Magnetic Ride Control™
The vehicle may have Magnetic Ride Control that
automatically adjusts the ride of the vehicle.
The controller receives input from the system to
determine the proper ride. If the controller detects a
problem within the system, the Driver Information
Center (DIC) displays a SERVICE SUSPENSION SYS
message. SeeDIC Warnings and Messages on
page 3-73for more information. If this message appears,
have the vehicle serviced at your dealer/retailer.
Electronically Controlled Air Ride
Suspension
Professional Vehicles may have Electronically Controlled
Air Suspension. The air ride controller receives input
from the system to determine the proper ride. If the
controller detects a problem with the system, the DIC
will display a SERVICE SUSPENSION SYS message.
If this message appears, have the vehicle serviced
at your dealer/retailer.
Steering
Power Steering
If power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.
Magnetic Speed Variable Assist
Steering System
This system continuously adjusts the effort felt when
steering at all vehicle speeds. It provides ease
when parking, yet a rm, solid feel at highway speeds.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until out of the curve, and then accelerate
gently into the straightaway.
4-8

Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and nd
a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. These
problems can be avoided by braking — if you can stop
in time. But sometimes you cannot stop in time
because there is no room. That is the time for evasive
action — steering around the problem.
The vehicle can perform very well in emergencies like
these. First apply the brakes. SeeBraking on page 4-4.
It is better to remove as much speed as possible
from a collision. Then steer around the problem, to the
left or right depending on the space available.
An emergency like this requires close attention and a
quick decision. If holding the steering wheel at the
recommended 9 and 3 o’clock positions, it can be turned
a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
