CAUTION
■While driving
●Keep the back door closed while driving.
If the back door is left open, it may hit near-by objects while driving or lug-
gage may be unexpectedly thrown out, causing an accident.
In addition, exhaust gases may enter the vehicle, causing death or a seri-
ous health hazard. Make sure to close the back door before driving.
● Before driving the vehicle, make sure that the back door is fully closed. If
the back door is not fully closed, it may open unexpectedly while driving,
causing a passenger to be thrown out of the vehicle.
● Never let anyone sit in the luggage compartment. In the event of sudden
braking or a collision, they are susceptible to death or serious injury.
■ When children are in the vehicle
Observe the following precautions.
Failure to do so may result in death or serious injury.
●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 move unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing back door.

partment.
