Driving and Operating Manual Transmission If the vehicle is stationary, the ignition will turn OFF, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 9-21. The vehicle may have an electric steering column lock. The lock is activated when the vehicle is switched to OFF and either front door is opened. A sound may be heard as the lock actuates or releases. The steering column lock may not release with the wheels turned off center. If this happens, the vehicle may not start. Move the steering wheel from left to right while attempting to start the vehicle. If this does not work, the vehicle needs service. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags. If the vehicle must be shut off in an emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force. 2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving. After shifting to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location. 3. Come to a complete stop. Shift to P (Park) with an automatic transmission, or Neutral with a manual transmission. Turn the ignition to LOCK/OFF. 4. Set the parking brake. See Parking Brake (Electric) on page 9-30 or Parking Brake (Manual) on page 9-32. 9-17 { Warning Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency. If the vehicle cannot be pulled over, and must be shut off while driving, press and hold the ENGINE START/ STOP button for longer than two seconds, or press twice within five seconds. ACC/ACCESSORY (Amber Indicator Light): This mode allows you to use some electrical accessories when the engine is off. With the ignition off, pressing the button one time without the brake pedal applied will place the ignition system in ACC/ACCESSORY.
