9-16 Driving and Operating to the Keyless Access system. See Remote Keyless Entry (RKE) System Operation on page 2-2. To shift out of P (Park), the vehicle must be in ACC/ACCESSORY or ON/RUN, and the brake pedal must be applied. Stopping the Engine/OFF (No Indicator Lights): When the vehicle is stopped, press the ENGINE START/STOP button once to turn the engine off. The vehicle may have an electric steering column lock. The lock is activated when the vehicle is switched to OFF and the driver 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. Ignition Positions The vehicle has an electronic keyless ignition with pushbutton start. Pressing the button cycles it through three modes: ACC/ACCESSORY, ON/RUN/START, and Stopping the Engine/OFF. The Remote Keyless Entry (RKE) transmitter must be in the vehicle for the system to operate. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference If the vehicle is in P (Park), the ignition will turn off, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 9-19. If the vehicle is not in P (Park), the ignition will return to ACC/ ACCESSORY and display a message in the Driver Information Center (DIC). See Transmission Messages on page 5-46. When the vehicle is shifted into P (Park), the ignition system will switch to OFF.
