GMC Terrain: Front Seats / Lumbar Adjustment and Reclining Seatbacks
Lumbar Adjustment
If equipped, press and hold the front or rear of the control to increase or decrease lumbar support.
Reclining Seatbacks
Warning
Sitting in a reclined position when the vehicle is in motion can be dangerous. Even when buckled up, the seat belts cannot do their job.
The shoulder belt will not be against your body. Instead, it will be in front of you. In a crash, you could go into it, receiving neck or other injuries.
The lap belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries.
For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear the seat belt properly.
Do not have a seatback reclined if the vehicle is moving.
Power Seat Adjustment
Warning
The power seats will work with
the ignition off. Children could
operate the power seats and be
injured. Never leave children
alone in the vehicle...
Manual Reclining Seatbacks
Warning
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked...
