Seatback Reclining
Sitting in a reclined seat can be dangerous while the vehicle is moving. Even if the seat belt is fastened, reclining the seatback significantly reduces the protection provided by the restraint system (seat belt and/or airbags).
WARNING
NEVER sit in a reclined seat while the vehicle is moving.
This type of behavior increases the risk of serious injury or death in a collision or sudden braking.
The driver and passengers should ALWAYS sit upright and buckled, with their seatbacks upright.
To be effective, the belt must be positioned on the hips and chest. When the seatback is reclined, the lap portion of the seat belt may not be effective, as it will not be positioned on the hips. Instead, it may slide up over the abdomen. In a collision, you may slide under the belt, and the belt may cause injury to the neck or other parts of the body.
The more the seatback is reclined, the greater the risk of the occupant sliding under the lap portion of the seat belt or the neck contacting the belt in a collision.

Seat Height (Driver's Seat)
To adjust the seat height:
- Pump the lever several times to lower the seat.
