2005 GMC ENVOY XUV Owner's Manual

Midgate
{CAUTION:
It can be dangerous to drive with the cargo
area covered and the tailgate and the midgate
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the tailgate
and midgate open or if electrical wiring or
other cable connections must pass through
the seal between the body and the midgate:
Make sure all windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the
setting on outside air. That will force
outside air into your vehicle. SeeDual
Climate Control System on page 3-20.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-40.
Midgate
Your vehicle is equipped with a midgate and power
midgate glass. The midgate allows you to extend the
length of your vehicle’s cargo area.
Lowering the Midgate
The midgate can be lowered to allow the cargo area of
your vehicle to extend into the cab. The midgate
cannot be lowered when the glass is up.
To lower the midgate, do the following:
1. Fold and tumble the rear seats. The front seats might
have to be moved forward slightly to allow the rear
seats to fold and tumble. SeeRear Seat Operation
on page 1-6for more information.
2.
C(Midgate glass):Press this overhead console
button to lower the midgate glass with the key in the
ignition. The midgate can be lowered without the key
in the ignition if the midgate glass is already down.
{CAUTION:
When the midgate is raised or lowered,
unsecured safety belts can be damaged and
may not restrain you in a crash. To help avoid
personal injury, always secure belts in the
retainers before operating the midgate.
2-13

3. Clip the second row safety belts into the retainers.
They are mounted on the pillars below where the
safety belt passes through the trim panel. This
prevents the safety belt from being tangled in the
midgate when opening or closing the midgate.
4. Press the midgate release button located on the
driver’s side of the midgate while pulling the
release handle.
5. Lower the midgate and secure it in the down
position by engaging the midgate to the oor
support. The latch for the oor support is found on
the driver’s side of the vehicle.
Raising the Midgate
To return the midgate to its normal position, release the
midgate by pulling up on the lever found on the
driver’s side midgate support. Reverse the steps for
lowering the midgate listed previously. The midgate
must be fully latched on both sides before the midgate
glass can be raised.
Tailgate
Your vehicle is equipped with a tailgate which can be
swung out or opened at. It can be locked and unlocked
with the driver or passenger door power lock button
or the remote keyless entry transmitter. The tailgate has
power rear glass. The glass must be fully lowered to
open the tailgate to its at position.
The power roof and tailgate must both be fully closed to
raise the rear glass. If the roof or tailgate are not fully
closed, the words CLOSE THE ROOF or CLOSE
THE TAILGATE will appear on the DIC when you try
to raise the rear glass.
If the tailgate drop/swing, power roof, rear wiper and
rear window defogger functions are inoperative, or
SEE MANUAL– TAILGATE is displayed on the Driver
Information Center, the tailgate window position needs to
be reset. To reset the window position, activate the
tailgate window up switch and continue to hold it
for two seconds after the window is fully closed.
Then activate the tailgate window down switch and
continue to hold it for two seconds after the window is
fully open. If this process does not restore function,
see your dealer for service.

To close the tailgate, rmly push it toward the vehicle
until it latches. If the tailgate glass was fully closed when
you opened the tailgate, it will return to a fully closed
position when you close the tailgate.The tailgate is equipped with a prop rod to aid in

eight foot building material when placed in the
secondary position. In the secondary position, the

tailgate in the at position, remove the prop rod from the
retaining clip on the driver’s side. Rotate the rod forward
and engage the end of the slotted stud on the side of
the vehicle opening. Push down to lock the rod in place.

Windows
{CAUTION:
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.
Pets can be in the rear cargo area only if
adequate ventilation is provided. With the roof,
midgate, and endgate window closed, the rear
cargo area of your XUV will have very little air
movement, whether you are parked or moving.
At a minimum, open the midgate window while
driving, and the endgate window while parked,
if you put a pet in the cargo area. Check
periodically that the ventilation is adequate.
