uu Braking u Brake System 2013 RDX QRG ■ Foot Brake Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist helps reduce the effort needed on the brake pedal. The brake assist system increases the stopping force when you depress the brake pedal hard in an emergency situation. The anti-lock brake system (ABS) helps you retain steering control when braking very hard. 2 Brake Assist System P. 260 2 ABS (Anti-lock Brake System) P. 259 1 Foot Brake Check the brakes after driving through deep water, or if there is a buildup of road surface water. If necessary, dry the brakes by lightly depressing the pedal several times. If you hear a continuous metallic friction sound when applying the brakes, the brake pads need to be replaced. Have the vehicle checked by a dealer. Constantly using the brake pedal while going down a long hill builds up heat, which reduces the brake effectiveness. Apply engine braking by taking your foot off the accelerator pedal and downshifting to a lower gear. TOC Driving Do not rest your foot on the brake pedal while driving, as it will lightly apply the brakes and cause them to lose effectiveness over time and reduce pad life. It will also confuse drivers behind you. Your vehicle is equipped with a hydraulic brake booster that, under certain conditions, such as braking at high altitudes, supplements the vacuum power assist. When the hydraulic brake booster activates, you may hear a motor sound and a slight vibration in the pedal. This is normal. Index 258
