GM Service Manual Online
For 1990-2009 cars only

Move your shift lever to PARK (P) or NEUTRAL (N). Your engine will not start in any other position -- that is a safety feature. To restart when you are already moving, use NEUTRAL (N) only.

The keyless access transmitter must be in the vehicle for the ignition to work.

Notice: Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.

  1. With your foot on the brake pedal, press the START button located on the instrument panel. If there is not a keyless access transmitter present or if there is something causing interference with it, the DIC will display NO FOB DETECTED. See DIC Warnings and Messages for more information. When the engine begins cranking, let go of the button. The idle speed will go down as your engine gets warm.
  2. If the battery in the keyless access transmitter is weak, the DIC will display FOB BATTERY LOW. You can still drive the vehicle. See "Battery Replacement" under Keyless Access System Operation for more information.

    Notice: Holding the button in for longer than 15 seconds at a time will cause the vehicle's battery to be drained much sooner. This can also cause damage to the starter motor. Wait 15 seconds between each try to avoid draining your vehicle's battery or damaging the starter.

  3. If the engine does not start and no DIC message is displayed, wait 15 seconds before trying again.

Notice: The engine is designed to work with the electronics in the vehicle. If electrical parts or accessories are added, you could change the way the engine operates. Before adding electrical equipment, check with your dealer/retailer. If you do not, the engine might not perform properly. Any resulting damage would not be covered by the vehicle warranty.

Stopping Your Engine

Move the shift lever to PARK (P) and press the ACC button located on the instrument panel. If the shifter is not in PARK (P), the vehicle will go into the accessory mode, the engine will turn off and the DIC will display SHIFT TO PARK. When the shifter is moved to PARK (P), the vehicle will go into the RAP mode, if all doors are closed. The ignition mode will change to OFF, if a front door is opened. See Retained Accessory Power (RAP) for more information.

If the keyless access transmitter is not detected while going to off, the DIC will display NO FOB - OFF OR RUN?
