Engine Emission Control

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked by an authorized dealer. Ifthe vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 321).
See Warning Lamps andIndicators (page 104).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
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.
Brake Assist
Brake assist detects when you rapidly brakeby measuring the rate at which you press thebrake pedal. It provides maximum brakingefficiency as long as you press the pedal.Brake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarily illuminateswhen you switch the ignition on. Ifthe light does not illuminate duringstart up, remains on or flashes, the anti-lockbraking system may be disabled. Have thesystem checked by an authorized dealer. Ifthe anti-lock brake system is disabled,normal braking is still effective.
If the brake warning lampilluminates when you release theparking brake, have your systemchecked by an authorized dealer. It alsoilluminates momentarily when you switch theignition on to confirm the lamp is functional.If it does not illuminate when you switch theignition on or begins to flash at any time,have the system checked by an authorizeddealer.
Note:The brake warning lamp mayilluminate and stay illuminated until youswitch off your vehicle as a result of drivingat high elevation.
