Folding the Rear Seat
The rear seat backs can be folded down to facilitate transporting long items or to increase the cargo capacity of the vehicle.
WARNING - Folded Seatback
The folding rear seatbacks allow you to carry longer items that could not otherwise be accommodated.
- Never allow a passenger to sit on a folded seatback while the vehicle is moving. This is an improper seating position, as the seat's important collision protection features and seat belts are not available in this seat configuration.
- To reduce the risk of injury caused by cargo sliding inside the passenger compartment, items carried on the folded seatback must not extend above the top of the front seats.

To fold the rear seatback:
1. Make sure the rear seat belt webbing is in the guide to prevent damage.
2. Place the front seatback in the upright position and, if necessary, move the front seat forward.
3. Lower the rear headrests to their lowest position.
WARNING! Objects
Items carried on the folded seatback must not extend above the top of the front seatbacks. This may allow the cargo to slide forward and cause injury or damage during sudden stops.


4. Pull the seatback lock handle (1) in the luggage compartment, then fold the seat forward.
5. To use the rear seat, lift and pull the seatback rearward. Pull the seatback firmly until it locks into place with a click. Make sure the seatback is locked.
6. Return the rear seat belt to its correct position.
CAUTION
Be careful when loading cargo through the rear passenger seats to avoid damaging the vehicle interior.
WARNING
If the driver's seating position is not properly set according to your physique, do not fold down the rear seat. This may increase the risk of body injury in a sudden stop or collision.
WARNING - Upright Seating
When returning the seatback to the upright position, hold the seatback and return it slowly. If the seatback is returned without holding it, the seatback may spring forward, which may cause injury from being struck by the seatback.
CAUTION! Rear Seatback
To ensure maximum protection in the event of an accident or sudden stop, when returning the rear seatback to the upright position:
- Be careful not to damage the seat belt webbing or buckle.
- Do not allow the seat belt webbing or buckle to be pinched or trapped in the rear seat.
- Make sure the seatback is fully locked in the upright position by pressing on the top of the seatback. Failure to follow any of these instructions may result in serious injury or death in an accident.
WARNING - Damage to Rear Seat Belt Buckles
When folding the rear seatback, insert the buckle between the rear seatback and the cushion. This helps prevent the buckle from being damaged by the seatback.
CAUTION - Rear Seat Belts
When returning the rear seatbacks to the upright position, make sure the rear shoulder belts are correctly positioned.
WARNING - Cargo
Cargo must always be secured to prevent it from being thrown around the vehicle in a collision and injuring vehicle occupants. Do not place items on the rear seats, as they cannot be properly secured and may strike the front passenger seatback in a collision.
WARNING - Loading Cargo
Make sure the engine is off, the automatic transmission is in P (Park), and the parking brake is firmly applied when loading or unloading cargo. Failure to do so may cause the vehicle to move if the shift lever is unintentionally
