Operation CHARM: Car repair manuals for everyone.

Technician Safety Information

WARNING:
- Do not run the engine when jacking the vehicle. The wheels contacting the ground could cause the vehicle to move.
- Make sure the jack and jack stands are correctly located to prevent the vehicle from falling.
- A wheel chock should be used to prevent the vehicle from rolling and falling off the jack.
- When one of the rear wheels is off the ground, the transmission alone will not prevent the vehicle from moving or slipping off the jack, even if the transmission is in P (park) (automatic transmission) or reverse (manual transmission).
