1393-2. Opening, closing and locking the doors
3
Operation of each component
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Before driving
●Make sure that the back door is fully closed. If the back door is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the luggage compartment may be thrown out, causing an acci-
dent.
● Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could
have heat exhaustion or other injuries.
● Do not allow a child to open or close the back door.
Doing so may cause the back door to operate unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing back door.
■ Important points while driving
Never let anyone sit in the luggage compartment. In the event of sudden
braking, sudden swerving or a collision, they are susceptible to death or
serious injury.
■ Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
●Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.
● When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.
● If anyone is in the vicinity, make sure they are safe and let them know that
the back door is about to open or close.
● Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.
●The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an
incline than on a level surface, so
beware of the back door unexpectedly
opening or closing by itself. Make sure
that the back door is fully open and
secure before using the luggage com-
partment.

3-3. Adjusting the seats
WARNING
■When folding the rear seatbacks down
Observe the following precautions. Failure to do so may result in death or
serious injury.
●Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, set the parking brake and shift the shift
lever to P.
● Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● Be careful not to get any part of your body pinched by a seat.
■ Seat adjustment
●Be careful that the seat does not hit passengers or luggage.
● To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is reclined too far, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
■ After returning the rear seatbacks or installing seats
Observe the following precautions. Failure to do so may result in death or
serious injury.
●Make sure the seatback is securely locked by pushing it forward and rear-
ward on the top.
● Check that the seat belts are not twisted or caught in the seatback.
● Make sure the seat is locked in place by trying to shake the seatback and
lift up the seat cushion.
■ Removing the second seats
●Do not leave a seat in the vehicle if it has been disengaged from the floor.
● Do not sit on or place anything on a seat that has been removed from the
vehicle.
