9-16 Driving and Operating 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, 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 9‑33 or Parking Brake (Manual) on page 9‑32. { 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, switch the ignition to ACC/ ACCESSORY. 2 (ACC/ACCESSORY): This position allows you to use things like the radio and the windshield wipers when the engine is off. This position will allow you to turn off the engine. 3 (ON/RUN): This position is for driving. It is the position the ignition switch returns to after the engine starts, and the control knob is released. This position can also be used for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. If you need to shift the transmission out of P (Park), the ignition control knob has to be in ACC/ ACCESSORY or ON/RUN. The battery could be drained if you leave the ignition in the ACC/ ACCESSORY or ON/RUN position with the engine off. You may not be able to start the vehicle if the battery is allowed to drain for an extended period of time. 4 (START): This position starts the engine.
