Convenient features of your vehicle
To prevent possible damage to
the power window system, do
not open or close two windows
or more at the same time. This
will also ensure the longevity of
the fuse.
Never try to operate the main
switch on the driver's door and
the individual door window
switch in opposite directions at
the same time. If this is done, the
window will stop and cannot be
opened or closed.
NOTICE
NEVER leave the keys in your
vehicle with unsupervised
children, when the engine is
running.
NEVER leave any child unat-
tended in the vehicle. Even
very young children may inad-
vertently cause the vehicle to
move, entangle themselves in
the windows, or otherwise
injure themselves or others.
Always double check to make
sure all arms, hands, head
and other obstructions are
safely out of the way before
closing a window.
Do not allow children to play
with the power windows. Keep
the driver’s door power window
lock switch in the LOCK posi-
tion (pressed). Serious injury
can result from unintentional
window operation by the child.
Do not extend your head,
arms or body outside the win-
dows whilst driving.
