Important safety notes
GWARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system, and do not give them access to an unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. They could:
Rinjure themselves on vehicle parts
Rbe seriously or fatally injured by extreme
heat or cold
Rinjure themselves or have an accident with
vehicle equipment that may still be in oper-
ation even after the SmartKey has been
removed from the ignition, such as the seat
adjustment, steering wheel adjustment or
memory function.
If children open a door, they could cause
severe or even fatal injury to other persons; if they get out of the vehicle, they could injure
themselves when doing so or be seriously or
even fatally injured by any passing traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and a child could be burned on these
parts.
GWARNING
Do not carry heavy or hard objects in the
passenger compartment or cargo compart-
ment unless they are firmly secured in place.
Unsecured or improperly positioned cargo
increases a child's risk of injury in the event of
Rstrong braking maneuvers

Turn off the engine before opening the rear
door. Never drive with the rear door open.
