Driving Pull the release lever to release the brake. Driving with the parking brake on will cause the brakes to wear out quickly and reduce fuel economy. Park brake warning chime Sounds when the parking brake is set, the engine is running and the transaxle is not in P (Park) or N (Neutral). The chime will shut off when the parking brake is disengaged. TRACTION CONTROLி (IF EQUIPPED) Your vehicle may be equipped with the optional Traction Control௢ system. This system helps you maintain the stability and steerability of your vehicle. It is especially useful on slippery and/or hilly road surfaces. The system operates by detecting and controlling wheel spin. The system borrows many of the electronic and mechanical elements already present in the anti-lock braking system (ABS). Wheel-speed sensors allow excess front wheel spin to be detected by the Traction Control௢ portion of the ABS computer. Any excessive wheel spin is controlled by automatically applying and releasing the front brakes in conjunction with engine torque reductions. Engine torque reduction is realized via the fully electronic spark and fuel injection systems. This process is very sensitive to driving conditions and very fast acting. The front wheels "search" for optimum traction several times a second and adjustments are made accordingly. The Traction Control௢ system will allow your vehicle to make better use of available traction on slippery surfaces. The system is a driver aid which makes your vehicle easier to handle primarily on snow, ice covered and gravel roads. 142
