Lowering the Midgate with the Rear
Glass in Place
The midgate can be lowered to allow the
cargo area of your vehicle to extend into
the cab. The rear glass can be either
installed in its normal position, or it can be
removed and stored in the rear glass
storage pocket.
To lower the midgate:
1. Fold the rear seats. The front seats might have to be moved forward slightly
to allow the rear seats to fold. See Rear
Seats 049.
2. Standing outside of the vehicle, hold the midgate securely so it does not fall
forward. Press and hold the switch
button depending on configuration
below:
Glass and Crossbar in, Pass Through
Doors Only
.A short press on either switch button, of
less than two seconds opens the larger
door of the midgate.
.A long press on either switch button, of
two or more seconds opens both doors of
the midgate.
.A long press is needed to open the
smaller door if the larger door is
already open.

Midgate Lowered with Crossbar Attached
This procedure works the same as the
procedure described previously, but when
you lower the midgate with the rear glass
in the stored position, you will notice that
the entire crossbar will lower with the
midgate. This is completely normal;
however, since the crossbar lowers with the
midgate, it will be heavier. As you lower the
midgate be ready for the extra weight and
do not let the midgate fall as you lower it.
Raising the Midgate
To return the midgate to its normal
position:
1. Temporarily secure the seatbelt buckle to the opening slot in the door trim to
move it out of the path of the midgate.
2. Raise the midgate up with a firm swinging motion until it latches into
place securely. This will help to ensure
that the midgate closes with enough
force to engage the latches.
3. Once the midgate is securely latched, release the seatbelt buckle from the slot
in the door trim. If the rear glass is removed and you would
like to put it back, do so using the
instructions given previously.

3. Push the latch plate into the buckle untilit clicks.
Pull up on the latch plate to make sure
it is secure. If the belt is not long
enough, see Seat Belt Extender 059.
Position the release pushbutton on the
buckle so that the seat belt could be
quickly unbuckled if necessary.
If equipped with a shoulder belt height
adjuster, move it to the height that is
right for you. See "Shoulder Belt Height
Adjuster" later in this section for
instructions on use and important safety
information.4. To make the lap part tight, pull up on the shoulder belt.
To unlatch the belt, push the release
pushbutton on the buckle. The belt should
return to its stowed position.
Always stow the seat belt slowly. If the seat
belt webbing returns quickly to the stowed
position, the retractor may lock and cannot
be pulled out. If this happens, pull the seat
belt straight out firmly to unlock the
webbing, and then release it. If the webbing
is still locked in the retractor, see your
dealer.
Before a door is closed, be sure the seat belt
is out of the way. If a door is slammed
against a seat belt, damage can occur to
both the seat belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle may have a shoulder belt height
adjuster for the driver and front outboard
passenger positions.
Adjust the height so the shoulder portion of
the belt is on the shoulder and not falling
off of it. The belt should be close to, but not
contacting, the neck. Improper shoulder belt
height adjustment could reduce the
effectiveness of the seat belt in a crash. See
How to Wear Seat Belts Properly 054.
