BRAKE PRECAUTIONS
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when leaving a car wash ordriving from standing water to dry thebrakes.

ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEMLIMITATIONS
The anti-lock braking system does noteliminate the risk of crash when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and travel further.Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference.

Side Wind Stabilization
Side wind stabilization is an advancedfeature that works by carefully applyingthe brakes on one side of the vehicle toreduce the effect of a side wind gust onthe vehicle's path.
Torque Vectoring by Brakes
Torque vectoring control applies braketorque on the inner driven wheel in a curvefor better traction to avoid an understeer,or oversteer situation. Unlike electronicstability control, enhanced torquevectoring control does not slow thevehicle. It helps control excessive wheelslip and gives the vehicle improvedcornering agility.
Traction Control
Traction control enhances your vehicle’sability to maintain traction of the wheelsby detecting and controlling wheel spin.See What Is Traction Control (page 217).
