POWER STEERING ● HEADED UPHILL WITH CURB: 2 Turn the wheels away from the curb and move the vehicle back until the curb side wheel gently touches the curb. ● HEADED UPHILL OR DOWNHILL, NO CURB: 3 Turn the wheels toward the side of the road so the vehicle will move away from the center of the road if it moves. 4. Turn the ignition key to the LOCK position and remove the key. The power assisted steering is designed to use a hydraulic pump, driven by the engine, to assist steering. If the engine stops or the hydraulic pump drive belt breaks, you will still have control of the vehicle. However, much greater steering effort is needed, especially in sharp turns and at low speeds. WARNING If the engine is not running or is turned off while driving, the power assist for the steering will not work. Steering will be much harder to operate. BRAKE SYSTEM The brake system has two separate hydraulic circuits. If one circuit malfunctions, you will still have braking at two wheels. BRAKING PRECAUTIONS Vacuum assisted brake The brake booster aids braking by using engine vacuum. If the engine stops, you can stop the vehicle by depressing the brake pedal. However, greater foot pressure on the brake pedal will be required to stop the vehicle and stopping distance will be longer. Using the brakes Avoid resting your foot on the brake pedal while driving. This overheats the brakes, increases wear on the brake linings and pads, and reduces gas mileage. To help save the brakes and to prevent the brakes from overheating, reduce speed and downshift to a lower gear before going down a slope or long grade. Overheated brakes may reduce braking performance and could result in loss of vehicle control. Starting and driving 5-17
