9-18 Driving and Operating 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 on page 9‑31 The steering can bind with the wheels turned off center. If this happens, move the steering wheel from right to left while turning the key to ACC/ACCESSORY. If this doesn't work, then the vehicle needs service. ACC (ACC/ACCESSORY): This position operates some of the electrical accessories, such as the radio, but not the climate control system. ON (ON/RUN): This position can be used to operate the electrical accessories, and to display some instrument panel cluster warning and indicator lights. The switch stays in this position when the engine is running. If you leave the key in the ACC/ACCESSORY or ON/RUN position with the engine off, the battery could be drained. You may not be able to start the vehicle if the battery is allowed to drain for an extended period of time. START: This is the position that starts the engine. When the engine cranks, release the key. The ignition switch returns to ON/RUN for driving. Do not turn the key to START if the engine is running. LOCK (STOPPING THE ENGINE/ LOCK/OFF): When the vehicle is stopped, turn the ignition switch to LOCK/OFF to turn the engine off. This position locks the steering wheel, ignition, shift lever and transmission. This is the only position in which you can insert or remove the key. 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. 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, firmly apply the brakes and steer the vehicle to a safe location.
