Buick Enclave: Ignition Positions (Keyless Access)
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 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 to the keyless access system. See Remote Keyless Entry (RKE) System Operation for more information.
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.
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) for more information.
If the vehicle is not in P (Park), the ignition will return to ACC/ ACCESSORY and the Driver Information Center (DIC) will display a message. See Transmission Messages for more information. When the vehicle is shifted into P (Park), the ignition system will switch to OFF.
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), and turn the ignition to Stopping the Engine/OFF. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to the Stopping the Engine/OFF position.
4. Set the parking brake. See Parking Brake .
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.
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.
The ignition will switch from ACC/ACCESSORY to OFF after five minutes to prevent battery rundown.
ON/RUN/START (Green Indicator Light): This mode is for driving and starting. With the ignition off, and the brake pedal applied, pressing the button once will place the ignition system in ON/RUN/START. Once engine cranking begins, release the button. Engine cranking will continue until the engine starts. See Starting the Engine for more information. The ignition will then remain in ON/RUN.
