Retained Accessory Power (RAP) If the vehicle has Retained Accessory Power (RAP), certain features will continue to operate for up to 10 minutes after the ignition key is turned to LOCK unless a door is opened. Automatic Transmission Move your shift lever to PARK (P) or NEUTRAL (N). Your engine will not start in any other position - that is a safety feature. To restart when you are already moving, use NEUTRAL (N) only. If you have a diesel engine refer to the diesel supplement for the starting procedure. Notice: Do not try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped. Starting the Engine Your vehicle has a Starter Motor Control. This feature assists in starting the engine and protects the electrical system. This feature may cause the engine to crank even after the ignition key is not in START. Manual Transmission The gear selector should be in NEUTRAL (N) and the parking brake engaged. Hold the clutch pedal to the floor and start the engine. Your vehicle will not start if the clutch pedal is not all the way down - that is a safety feature. 136
