Precision Control System (PCS) (Option) If your vehicle is equipped with PCS, this system helps your vehicle to go in the direction you are steering in difficult driving conditions. This is accomplished when the computer senses that your vehicle is starting to spin and assists the driver by selectively applying any one of the vehicle's brakes. When PCS is active, the LOW TRAC light will come on. Continue to steer in the direction you want the vehicle to go and apply the brakes normally to slow the vehicle as desired. You may hear or feel the system working, but this is normal. You should adjust your driving accordingly. See "Low Traction Active (LOW TRAC) Light" in the Index. United States Canada When you first start the vehicle, the PCS light should come on briefly. If the light doesn't come on then, have your vehicle serviced so it will be ready to warn you if there is a problem. If you ever see the PCS warning light come on, it means there is a PCS problem. If both the PCS and TRAC OFF lights are on, neither the PCS nor the traction control system are functioning. You can try resetting the system: stop, turn off the engine, wait a few seconds and then start the engine again. If both lights are still on, you should have your vehicle serviced. 4-11
