Keeping pace with the traffic and allowing realisticfollowing distances eliminates a lot of unnecessarybraking. That means better braking and longer brake life.
If the engine ever stops while the vehicle is being driven,brake normally but do not pump the brakes. If the brakesare pumped, the pedal could get harder to push down.If the engine stops, there will still be some power brakeassist but it will be used when the brake is applied. Oncethe power assist is used up, it can take longer to stop andthe brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affectvehicle performance. SeeAccessories and Modificationson page 6-3.
Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), anadvanced electronic braking system that helps prevent abraking skid.
When the engine is started and the vehicle begins todrive away, ABS checks itself. A momentary motoror clicking noise might be heard while this test is goingon, and it might even be noticed that the brake pedalmoves a little. This is normal.
If there is a problem withABS, this warning lightstays on. SeeAntilockBrake System (ABS)Warning Light onpage 4-53.
Let us say the road is wet and you are driving safely.Suddenly, an animal jumps out in front of you. You slamon the brakes and continue braking. Here is whathappens with ABS:
A computer senses that the wheels are slowing down.If one of the wheels is about to stop rolling, the computerwill separately work the brakes at each front wheeland at both rear wheels.
ABS can change the brake pressure to each wheel, asrequired, faster than any driver could. This can helpthe driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keepsreceiving updates on wheel speed and controls brakingpressure accordingly.
Remember: ABS does not change the time needed to geta foot up to the brake pedal or always decrease stoppingdistance. If you get too close to the vehicle in front of you,there will not be enough time to apply the brakes if thatvehicle suddenly slows or stops. Always leave enoughroom up ahead to stop, even with ABS.

Using ABS
Do not pump the brakes. Just hold the brake pedaldown firmly and let antilock work. The antilock pump ormotor operating might be heard and the brake pedalmight be felt to pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the sametime. In many emergencies, steering can help more thaneven the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed toassist the driver in stopping or decreasing vehicle speedin emergency driving conditions. This feature uses thestability system hydraulic brake control module tosupplement the power brake system under conditionswhere the driver has quickly and forcefully appliedthe brake pedal in an attempt to quickly stop or slowdown the vehicle. The stability system hydraulicbrake control module increases brake pressure at eachcorner of the vehicle until the ABS activates. Minorbrake pedal pulsations or pedal movement during thistime is normal and the driver should continue toapply the brake pedal as the driving situation dictatesThe Brake Assist feature will automatically disengagewhen the brake pedal is released or brake pedalpressure is quickly decreased.
StabiliTrak®System
The vehicle may have the StabiliTrak system whichcombines antilock brake, traction and stability controlsystems and helps the driver maintain directional controlof the vehicle in most driving conditions. This isaccomplished by selectively applying any one of thevehicle’s brakes and reducing engine power.
The StabiliTrak system comes on automaticallywhenever the vehicle is started. The system cannot beturned off.
This light will flash whenthe system is operating.
The STABILITRAK NOT READY message may bedisplayed in the Driver Information Center (DIC) and theTraction Control System (TCS)/StabiliTrak warninglight on the instrument panel cluster comes on after firstdriving the vehicle and exceeding 19 mph (30 km/h)for 30 seconds. The StabiliTrak system is off untilthe light has turned off. This could take up to 15 minutes.

The TCS/StabiliTrak warning light on the instrumentpanel cluster will flash when the system is operating.SeeTraction Control System (TCS) Warning Lighton page 4-54andStabiliTrak®Indicator Light onpage 4-54for more information. The system may beheard or felt while it is working. This is normal.
The SERVICE STABILITRAK message is displayed andthe TCS/StabiliTrak warning light on the instrumentpanel cluster comes on if there is a problem with thesystem. When this light and the SERVICESTABILITRAK message are on, the system is notworking. Adjust your driving accordingly.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) thatlimits wheel spin. This is especially useful in slippery roadconditions. The system operates only if it senses that thefront wheels are spinning too much or beginning to losetraction. When this happens, the system works the frontbrakes and reduces engine power (by closing the throttleand managing engine spark) to limit wheel spin.
The TCS and StabiliTrak®
light will flash when thesystem is limitingwheel spin.
The system may be heard or felt while it is working, butthis is normal. SeeTraction Control System (TCS)Warning Light on page 4-54for more information.
If the vehicle is in cruise control when TCS begins tolimit wheel spin, the cruise control will automaticallydisengage. The cruise control may be re-engaged whenroad conditions allow. SeeCruise Control on page 4-12.
The SERVICE TRACTION CONTROL message inthe DIC and the TCS/StabiliTrak warning light comes onif there is a problem with the traction control system.SeeDIC Warnings and Messages on page 4-67.
When this light and the SERVICE TRACTIONCONTROL message are on, the system will not limitwheel spin. Adjust your driving accordingly.

To turn the system off oron, press and release thisbutton located in frontof the shift lever.
TCS automatically comes on whenever the vehicle isstarted. To limit wheel spin, especially in slipperyroad 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 bypressing the TCS button. The DIC will displayTRACTION 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 willnot be able to use the engine speed managementsystem. System noises may be heard as a result of thebrake-traction control working. If the controller detectsexcessive wheel spin in this mode, the TCS/StabiliTraklight may blink.
It is recommended to leave the system on for normaldriving conditions, but it may be necessary to turnthe system off if the vehicle is stuck in sand, mud, ice orsnow, and you want to “rock” the vehicle to attempt tofree it. SeeIf Your Vehicle is Stuck in Sand, Mud, Ice, orSnow on page 5-17.
Adding non-dealer/non-retailer accessories can affectthe vehicle’s performance. SeeAccessories andModifications on page 6-3for more information.
Magnetic Ride Control™
The vehicle may have Magnetic Ride Control thatautomatically adjusts the ride of the vehicle. Thecontroller receives input from the system to determinethe proper ride. If the controller detects a problem withinthe system, the Driver Information Center (DIC)displays a SERVICE SUSPENSION SYS message.SeeDIC Warnings and Messages on page 4-67for more information. If this message appears, have thevehicle serviced at your dealer/retailer.
Electronically Controlled Air Ride
Suspension
Professional Vehicles may have Electronically ControlledAir Suspension. The air ride controller receives inputfrom the system to determine the proper ride.

Steering
Power Steering
If power steering assist is lost because the engine stopsor the system is not functioning, the vehicle can besteered but it will take more effort.
Magnetic Speed Variable Assist
Steering System
This system continuously adjusts the effort felt whensteering at all vehicle speeds. It provides easewhen parking, yet a firm, 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 tiresand the road surface, the angle at which the curve isbanked, and vehicle speed. While in a curve, speed isthe one factor that can be controlled.
If there is a need to reduce speed, do it before enteringthe curve, while the front wheels are straight.
Try to adjust the speed so you can drive through thecurve. Maintain a reasonable, steady speed. Waitto accelerate until out of the curve, and then accelerategently into the straightaway.
Steering in Emergencies
There are times when steering can be more effectivethan braking. For example, you come over a hill and finda truck stopped in your lane, or a car suddenly pullsout from nowhere, or a child darts out from betweenparked cars and stops right in front of you. Theseproblems can be avoided by braking — if you can stopin time. But sometimes you cannot stop in timebecause there is no room. That is the time for evasiveaction — steering around the problem.
The vehicle can perform very well in emergencies likethese. First apply the brakes. SeeBraking on page 5-3.It is better to remove as much speed as possiblefrom a collision. Then steer around the problem, to theleft or right depending on the space available.
