BRAKE PRECAUTIONS
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when leaving a car wash or drivingfrom standing water to dry the brakes.
Note:Depending on applicable laws andregulations in the country where your vehiclewas originally built, the stoplamps could flashduring heavy braking. The hazard warningflashers could also turn on when your vehiclecomes to a stop.
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 pedal becomesstuck or entrapped, apply steady and firmpressure to the brake pedal to slow thevehicle and reduce engine power. If youexperience this condition, apply the brakesand bring your vehicle to a safe stop. Movethe transmission to park (P), switch theengine off and apply the parking brake.Inspect the accelerator pedal for anyinterference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
LOCATING THE BRAKE FLUID
RESERVOIR
