Driving Refer to Brake system warning light in the Instrument Cluster chapter for information on the brake system warning light. Four-wheel anti-lock brake system (ABS) Your vehicle is equipped with an Anti-lock Braking System (ABS). This system helps you maintain steering control during emergency stops by keeping the brakes from locking. Noise from the ABS pump motor and brake pedal pulsation may be observed during ABS braking and the brake pedal may suddenly travel a little farther as soon as ABS braking is done and normal brake operation resumes. These are normal characteristics of the ABS and should be no reason for concern. ABS warning lamp The ABS lamp in the instrument cluster momentarily illuminates ABS when the ignition is turned on. If the light does not illuminate during start up, remains on or flashes, the ABS may be disabled and may need to be serviced. Even when the ABS is disabled, ! P normal braking is still effective. (If your BRAKE warning lamp BRAKE illuminates with the parking brake released, have your brake system serviced immediately.) Brake Assist (if equipped as part of the AdvanceTracா system) The Brake Assist system provides full braking force during panic braking situations. It detects a rapid application of the brake pedal and maximizes the amount of brake booster assist, helping the driver to achieve maximum braking pressure. Once a panic brake application is detected, the system will remain activated as long as the brake pedal is depressed. The system is deactivated by releasing the brake pedal. When the system activates, the brake pedal will travel with very little effort; this is normal. ! P BRAKE 199 2005 Mountaineer (mnt) Owners Guide (post-2002-fmt) USA (fus)
