Doors and Locks
Door Locks
{WARNING:
Unlocked doors can be dangerous.
.Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle will
not open it. The chance of being thrown out of
the vehicle in a crash is increased if the doors
are not locked. So, all passengers should
wear safety belts properly and the doors
should be locked whenever the vehicle is
driven.
.Young children who get into unlocked vehicles
may be unable to get out. A child can be
overcome by extreme heat and can suffer
permanent injuries or even death from heat
stroke. Always lock the vehicle whenever
leaving it.(Continued)
WARNING: (Continued)
.Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
Because the vehicle has the theft-deterrent system, you
must unlock the doors with the key or RKE transmitter
to avoid setting off the alarm.
From the outside, use either the key or the
RKE transmitter.
From the inside, use the power door lock switches or
manual lock knobs. The manual lock knobs are located
at the top of the door panel near the window.
Push the manual lock knob down to lock the door. To
unlock the door, pull up on the knob.

Windows
{WARNING:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat and
suffer permanent injuries or even death from heat
stroke. Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the windows
closed in warm or hot weather.
The vehicle aerodynamics are designed to improve fuel
economy performance. This may result in a pulsing
sound when either rear window is down and the front
windows are up. To reduce the sound, open either a
front window or the sunroof (if equipped).

Power Windows
{WARNING:
Leaving children in a vehicle with the keys is
dangerous for many reasons. Children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function and they could be seriously injured or
killed if caught in the path of a closing window. Do
not leave keys in a vehicle with children.
When there are children in the rear seat use the
window lockout button to prevent unintentional
operation of the windows.
The power window
switches are located on
the driver door.

Express Window Anti-Pinch Feature
If any object is in the path of the window when the

obstruction and auto‐reverse to a preset factory
position. Weather conditions such as severe icing
may also cause the window to auto‐reverse. The
window will return to normal operation once the
obstruction or condition is removed.
Express Window Anti‐Pinch Override
{WARNING:
If express override is activated, the window will
not reverse automatically. You or others could be
injured and the window could be damaged. Before
you use express override, make sure that all
people and obstructions are clear of the
window path.
In an emergency, the anti‐pinch feature can be
overridden in a supervised mode. Hold the window
switch all the way up to the second position. The
window will rise for as long as the switch is held.
Once the switch is released, the express mode is
re‐activated.
In this mode, the window can still close on an object in
its path. Use care when using the override mode.
