9-4 Driving and Operating If the vehicle seems harder to steer than normal when parking or driving slowly, there may be a problem with the system. You will still have power steering, but steering will be stiffer than normal at slow speeds. See your dealer for service. If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops, there will be some power brake assist but it will be used when the brake is applied. Once the power assist is used up, it can take longer to stop and the brake pedal will be harder to push. Caution (Continued) damage may occur to the power steering system and there may be loss of power steering assist. Hydraulic Power Steering This vehicle has hydraulic power steering. It may require maintenance. See Power Steering Fluid on page 10-18. If power steering assist is lost because the engine stops, or there is a system malfunction, the vehicle can be steered but may require increased effort. See your dealer if there is a problem. Curve Tips . Take curves at a reasonable speed. Reduce speed before entering a curve. Maintain a reasonable, steady speed through the curve. Wait until the vehicle is out of the curve before accelerating gently into the straightaway. There are some situations when steering around a problem may be more effective than braking. Holding both sides of the steering wheel allows you to turn 180 degrees without removing a hand. . Steering Variable Effort Steering Some vehicles have a steering system that varies the amount of effort required to steer the vehicle in relation to the speed of the vehicle. The amount of steering effort required is less at slower speeds to make the vehicle more maneuverable and easier to park. At faster speeds, the steering effort increases to provide a sport-like feel to the steering. This provides maximum control and stability. . . { Caution If the steering wheel is turned until it reaches the end of its travel, and is held in that position for more than 15 seconds, (Continued) Steering in Emergencies . .
