with remote control and a removable

checked every time you pull an outside door

When you open a door, the side windows on
that side lowers slightly. Once you close the
door, the window moves up again.
! A side window will not work if it is blocked
with ice or if the vehicle battery is
discharged. If you cannot shut a door, do
not force it or you could damage the door
or side window. Fix whatever is affecting
the window before trying to shut the door.
