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.

Battery chargers, such as those used for cell phones, may interfere with the operation of the Keyless Access System. Battery chargers should not be plugged in when starting or shutting off the engine.

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. If there is not a keyless access transmitter present, 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.

  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. If the shifter is not in PARK (P), the vehicle will go into accessory mode and the DIC will display SHIFT TO PARK. Once the shifter is moved to PARK (P), the vehicle will turn off.

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

See DIC Warnings and Messages for more information.
