Braking in EmergenciesABS allows the driver to steer and brake at the sametime. In many emergencies, steering can help more thaneven the very best braking.Brake AssistThis vehicle has a Brake Assist feature designed to assistthe driver in stopping or decreasing vehicle speed inemergency driving conditions. This feature uses thestability system hydraulic brake control module tosupplement the power brake system under conditionswhere the driver has quickly and forcefully applied thebrake pedal in an attempt to quickly stop or slow downthe vehicle. The stability system hydraulic brake controlmodule increases brake pressure at each corner of thevehicle until the ABS activates. Minor brake pedalpulsations or pedal movement during this time is normaland the driver should continue to apply the brake pedalas the driving situation dictates The Brake Assist featurewill automatically disengage when the brake pedal isreleased or brake pedal pressure is quickly decreased.StabiliTrak® SystemThe vehicle has a vehicle stability enhancement systemcalled StabiliTrak. It is an advanced computer controlledsystem that assists the driver with directional control ofthe vehicle in difficult driving conditions.StabiliTrak activates when the computer senses adiscrepancy between the intended path and the directionthe vehicle is actually traveling. StabiliTrak selectivelyapplies braking pressure at any one of the vehicle’sbrakes to assist the driver with keeping the vehicle on theintended path.When the vehicle is started and begins to move, thesystem performs several diagnostic checks to insurethere are no problems. The system may be heard or feltwhile it is working. This is normal and does not meanthere is a problem with the vehicle. The system shouldinitialize before the vehicle reaches 20 mph (32 km/h).In some cases, it may take approximately two miles ofdriving before the system initializes.If cruise control is being used when StabiliTrak activates,the cruise control automatically disengages. The cruisecontrol can be re-engaged when road conditions allow.See Cruise Control on page 3-13.5-6
