2008 CADILLAC ESCALADE EXT ECU

The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag if:
The right front passenger seat is unoccupied.
The system determines that an infant is present
in a rear-facing infant seat.
The system determines that a small child is
present in a child restraint.
The system determines that a small child is
present in a booster seat.
A right front passenger takes his/her weight off
of the seat for a period of time.
The right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger’s frontal airbag, the off indicator
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 3-33.If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint
following the child restraint manufacturer’s directions
and refer toSecuring a Child Restraint in the Right Front
Seat Position on page 1-53.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint
is not trapped under the vehicle head restraint.
If this happens, adjust the head restraint. SeeHead
Restraints on page 1-9.
Remove any additional material from the seat such
as blankets, cushions, seat covers, seat heaters,
or seat massagers before reinstalling or securing the
child restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle,
and check with your dealer/retailer.

In addition, your vehicle has a passenger sensing
system for the right front passenger’s position,
which includes sensors that are part of the
passenger’s seat. The passenger sensing system
may not operate properly if the original seat
trim is replaced with non-GM covers, upholstery
or trim, or with GM covers, upholstery or trim
designed for a different vehicle. Any object, such as
an aftermarket seat heater or a comfort enhancing
pad or device, installed under or on top of the
seat fabric, could also interfere with the operation of
the passenger sensing system. This could either
prevent proper deployment of the passenger
airbag(s) or prevent the passenger sensing system
from properly turning off the passenger airbag(s).
SeePassenger Sensing System on page 1-65.

Rear Glass Removal and Storage
{CAUTION:
If the removable rear glass is not stored
properly, it could be thrown about the vehicle
in a crash or sudden maneuver. People in
the vehicle could be injured. Whenever you
store the rear glass in the vehicle, always be
sure that it is stored securely in the Midgate
®
storage pocket.
Do not remove the rear glass when the rear defroster
is on. If you remove the rear glass with the rear defroster
on, you may see a discharge spark coming from the
latch area.

Once both glass lock knobs are in the locked
position, the rear glass is securely stored.
7. Push both latch levers up to the locked position.
You should hear a click when each latch lever
locks correctly.
The rear seats can be returned to the normal
position when the rear glass is out and stored
properly in the storage pocket.
Reinstalling the Rear Glass
To reinstall the rear glass, do the following:
1. Squeeze and pull down the latch levers (A), located
near the upper corners of the rear glass, to unlatch.
2. Hold the rear glass in place with one hand and turn
the glass lock knobs, located at both top corners of
the glass storage pocket, to the unlocked position.
3. Pull the rear glass out from the storage pocket
using the grab handles.

Lowering the Midgate®with the
Rear Glass in the Storage Pocket
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, raise the
Midgate®up with a rm swinging motion until it latches
into place securely. This will help to ensure that the
Midgate
®closes with enough force to engage the latches. Rear Glass Stored in Glass Storage Pocket
