break out of the cover. The inflator, the
airbag, and related hardware are all part of
the airbag module.
For airbag locations, seeWhere Are the
Airbags? 038.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact
the steering wheel or the instrument panel.
In moderate to severe side collisions, even
belted occupants can contact the inside of
the vehicle.
Airbags supplement the protection provided
by seat belts by distributing the force of the
impact more evenly over the
occupant's body.
Rollover capable roof-rail airbags are
designed to help contain the head and chest
of occupants in the outboard seating
positions in the first, second, and third rows,
if equipped. The rollover capable roof-rail
airbags are designed to help reduce the risk
of full or partial ejection in rollover events,
although no system can prevent all such
ejections. But airbags would not help in many types
of collisions, primarily because the
occupant's motion is not toward those
airbags. See
When Should an Airbag Inflate?
0 40.
Airbags should never be regarded as
anything more than a supplement to seat
belts.
What Will You See after an
Airbag Inflates?
After frontal and seat-mounted side impact
airbags (if equipped) inflate, they quickly
deflate, so quickly that some people may
not even realize the airbags inflated.
Roof-rail airbags (if equipped) may still be at
least partially inflated for some time after
they inflate. Some components of the airbag
module may be hot for several minutes. For
location of the airbags, see Where Are the
Airbags? 038.
The parts of the airbag that come into
contact with you may be warm, but not too
hot to touch. There may be some smoke
and dust coming from the vents in the
deflated airbags. Airbag inflation does not
prevent the driver from seeing out of the windshield or being able to steer the
vehicle, nor does it prevent people from
leaving the vehicle.
{Warning
When an airbag inflates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the
vehicle after an airbag inflates, then get
fresh air by opening a window or a door.
If you experience breathing problems
following an airbag deployment, you
should seek medical attention.
The vehicle has a feature that may
automatically unlock the doors (if equipped
with power door locks), turn on the interior
lamps and hazard warning flashers, and shut
off the fuel system after the airbags inflate.
The feature may also activate, without
airbag inflation, after an event that exceeds
a predetermined threshold. After turning the
ignition off and then on again, the fuel
system will return to normal operation; the

Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583525) - 2021 - CRC - 12/9/20
42 Seats and Restraints
doors can be locked, the interior lamps can
be turned off, and the hazard warning
flashers can be turned off using the controls
for those features. If any of these systems
are damaged in the crash they may not
operate as normal.
{Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle, such
as the fuel system, brake and steering
systems, etc. Even if the vehicle appears
to be drivable after a moderate crash,
there may be concealed damage that
could make it difficult to safely operate
the vehicle.
Use caution if you should attempt to
restart the engine after a crash has
occurred.
In many crashes severe enough to inflate
the airbag, windshields are broken by
vehicle deformation. Additional windshield
breakage may also occur from the front
outboard passenger airbag.
.Airbags are designed to inflate only once.
After an airbag inflates, you will need
some new parts for the airbag system.
If you do not get them, the airbag
system will not be there to help protect
you in another crash. A new system will
include airbag modules and possibly other
parts. The service manual for the vehicle
covers the need to replace other parts.
.The vehicle has a crash sensing and
diagnostic module which records
information after a crash. See Vehicle
Data Recording and Privacy 0274 and
Event Data Recorders 0275.
.Let only qualified technicians work on the
airbag systems. Improper service can
mean that an airbag system will not work
properly. See your dealer for service.
Airbag On-Off Switch
If the instrument panel has one of the
switches pictured in the following
illustrations, the vehicle has an airbag on-off
switch that you can use to manually turn
on or off the front outboard passenger
airbag. No other airbag is affected by the
airbag on-off switch.

Park Assist
If equipped, the Rear Park Assist (RPA)
system uses sensors on the rear bumper to
assist with parking and avoiding objects
while in R (Reverse).
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects below the bumper or that are
too close or too far from the vehicle. It is
not available at speeds greater than
8 km/h (5 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,
always check the area around the vehicle
and check all mirrors before backing.
How the System Works
RPA comes on automatically when the shift
lever is moved into R (Reverse). A single
beep sounds to indicate the system is
working.
RPA operates only at speeds less than
8 km/h (5 mph).An obstacle detection is indicated by beeps.
The time between beeps gets shorter as the
vehicle approaches the obstacle. Repeated
beeps are heard when the distance is less
than 30 cm (12 in).
To be detected, objects must be at least
25 cm (10 in) off the ground and below rear
door level. Objects must also be within 2.5 m
(8 ft) from the rear bumper. This distance
may be less during warmer or humid
weather.
Turning the System On and Off
The system can be disabled through the
Driver Information Center (DIC). See
“Park
Assist” underDriver Information Center (DIC)
0 81.
RPA defaults to the on setting each time the
vehicle is started.
Turn RPA off when towing a trailer.
When the System Does Not Seem to
Work Properly
The following messages may be displayed
on the DIC:
SERVICE PARK ASSIST : If this message
occurs, take the vehicle to your dealer for
repair. PARK ASSIST OFF :
This message occurs if
the driver disables the system or if the
vehicle is driven above 8 km/h (5 mph) in
R (Reverse).
PARK ASST BLOCKED SEE OWNERS
MANUAL : This message can occur under the
following conditions:
.The sensors are not clean. Keep the rear
bumper free of mud, dirt, snow, ice, slush,
and frost. The message may not clear
until frost or ice has melted all around
and inside the sensor.
.A trailer is attached to the vehicle, or a
bicycle or an object hanging out of the
rear door during the current or last drive
cycle. RPA will return to normal operation
after it is determined the object is
removed. This could take a few drive
cycles.
.A tow bar is attached to the vehicle.
Other conditions may affect system
performance, such as vibrations from a
jackhammer or the compression of air
brakes on a very large truck.
