Other information:
If you believe that your vehicle has a defect which could cause a crash or could
cause injury or death, you should immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to notifying General Motors.
If NHTSA receives similar complaints, it may open an investigation, and if it
finds that a safety defect exists in a group of vehicles, it may order a recall
and remedy campaign...
Warning
You can lose control of the vehicle if you try to adjust a driver seat
while the vehicle is moving. Adjust the driver seat only when the vehicle is not
moving.
To adjust a manual seat:
Pull the handle at the front of the seat.
Slide the seat to the desired position and release the handle...
