is checked every time you pull an outside
door handle.

G
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. It is possible for children
to open a locked door from the inside, which
could result in an accident and/or serious
personal injury.i
When you open a door, the side window on
that side lowers slightly. Once you close the
door, the window moves up again.
!
The side windows will not open or close if
the battery is discharged or the windows are cov-
ered with ice. As a result, you may no longer be
able to properly close the door. Do not attempt
to force the door shut. Doing so may damage the
door or the side window. Correct the condition
that prevents the windows from operating before
attempting to close the door.

ly as possible fastening materials appropri-
ate for the weight and size of the load.

den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.

sion or sudden maneuver, exercise care
when transporting cargo. Put luggage or car-
go in the trunk if possible. Do not pile lug-
gage or cargo higher than the seat backs.
