9-16 Driving and Operating The instruments and audio systems will operate as they do in ON/RUN, but the vehicle will not be able to be driven. The engine will not start in Service Only Mode. Push the button again to turn the vehicle off. { Caution Using a tool to force the key to turn in the ignition could cause damage to the switch or break the key. Use the correct key, make sure it is all the way in, and turn it only with your hand. If the key cannot be turned by hand, see your dealer. The key must be fully extended to start the vehicle. To shift out of P (Park), turn the ignition to ON/RUN and apply the brake pedal. 1 (STOPPING THE ENGINE/LOCK/ OFF): When the vehicle is stopped, turn the ignition switch to LOCK/ OFF to turn the engine off. Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 9-21. This is the only position from which the key can be removed. This locks the ignition and automatic transmission. 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 Neutral. This can be done while the vehicle is moving. After shifting to Neutral, continue to firmly apply the brakes and steer the vehicle to a safe location. Ignition Positions (Key Access) The ignition switch has four different positions.
