GM Service Manual Online
For 1990-2009 cars only

It is better not to park with the engine running. But if you ever have to, here are some things to know.

Caution: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier caution under Engine Exhaust .

Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control fan is at the highest setting. One place this can happen is a garage. Exhaust -- with CO -- can come in easily. NEVER park in a garage with the engine running.

Also see "If You Are Caught in a Blizzard" under Winter Driving .

Caution: It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Do not leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to PARK (P).

Follow the proper steps to be sure your vehicle will not move. See Shifting Into Park .

It is better not to park with the engine running. But if you ever have to, here are some things to know.

Caution: There is something about the vehicle that can make it move suddenly, and you or others can be seriously injured. This can happen if the vehicle is in the Auto Stop mode, and the shift lever is in D (Drive). Because the vehicle has the Automatic Engine Start/Stop feature, the vehicle's engine might seem to be shut off when you come to a complete stop. However, if you then start to exit the vehicle, as soon as you take your foot off the brake pedal, the engine will start again and the vehicle can move forward. If you are going to exit the vehicle, first shift to P (Park) and turn the ignition to LOCK/OFF. Then exit.
