You can lock the liftgate by pushing in the lock lever before you
begin to close the liftgate. You can also lock the liftgate by
closing the liftgate, inserting your key and turning it clockwise
until you hear the lock lever engage. If you turn it too far, the
optional liftgate window will open. The liftgate can also be
locked with the optional power door locks.
The liftgate area is intended only for cargo, not passengers. It
cannot be opened from inside the vehicle.
After the lock lever is depressed, the liftgate must be unlocked
with the power door lock button or the key.
NOTE: The lock lever will be on the right side of the lock
cylinder if your vehicle is equipped with the standard
liftgate glass. The lock lever will be on the left side
of the lock cylinder if your vehicle is equipped with the
optional flip-up liftgate window.

Power Windows (If equipped)
Each of the front doors has a power control that opens and closes
the window on that door. The driver door has master controls
that operate both front door windows. You must place the ignition
in the ON position to use your power window controls. The
driver's power window controls include a lockout button which
prevents the operation of the passenger side window from
either the passenger or driver side controls.
To open the window, press down on the switch; to close the
window, lift up on the switch.
Do not let children play with the power windows.
