2006 CHEVROLET EXPRESS CARGO VAN ECU

Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module, steering wheel, the instrument panel, or
airbag wiring can affect the operation of the airbag
system. If you have questions, call Customer
Assistance. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.
Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired. SeeCare of Safety Belts on
page 5-87for more information.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. The airbag system
does not need regular maintenance.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, the airbag
may not work properly. You may have to replace the
airbag module in the steering wheel or both the
airbag module and the instrument panel for the right
front passenger’s airbag. Do not open or break
the airbag coverings.

Section 2 Features and Controls
2-1

L(Panic Alarm):The remote keyless entry transmitter
comes equipped with an instant panic alarm. To use the
alarm, press the horn symbol while the ignition is turned
off. The horn will sound and both the interior and exterior
lamps will flash for up to thirty seconds. To stop the
instant panic alarm, press the panic button again, wait
for thirty seconds, or start the vehicle.
j(Cargo Door):Press this button to unlock the
cargo doors only.
Matching Transmitter(s) to
Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver.
The receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the lock and unlock buttons
on the transmitter at the same time for seven seconds.
The door locks should cycle to confirm synchronization.
If the locks do not cycle, see your dealer for service.

the power door lock switch
to lock all the doors at
once. Press the top side of
the power door lock
switch to unlock all the

When a door is locked, the inside door handle will

Cargo Door Relocking
This feature protects the owner from having an
unsecured side cargo door. If the side cargo door is
open when the lock button is pressed on the door or
the remote keyless entry transmitter, all doors will lock
and then relock again after the cargo door is closed.
If the cargo door is not closed within several minutes,
the relock will not occur.
Rear Door Security Locks
Security locks are located on the side sliding door, or the
front portion of the 60/40 side swing-out door. They are
also located on the passenger side rear cargo door of
some vehicles.
If your vehicle has security
locks on the rear cargo
door, you can lock these
doors so they cannot be
opened from the inside.
Move the lever down to engage the security feature.
Move the lever up to return the door locks to normal
operation.

Sun Visors
To block out glare, swing down the sun visors.
You can also swing them to the side.
Visor Vanity Mirror
You may have visor vanity mirrors, with or without
lamps. Lift the mirror cover to turn the lamps on,
if you have them.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it impossible to steal.
Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will go off
approximately five seconds after the key is turned to
RUN. SeeSecurity Light on page 3-40.
If the engine stalls and the SECURITY light flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine if you turn
the engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®
at this time. You may also want to check the fuse.
SeeFuses and Circuit Breakers on page 5-94.
See your dealer for service.

{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 1-73.
Passenger Airbag Status Indicator
If your vehicle has the passenger sensing system
then your instrument panel has a passenger airbag
status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light ON and
OFF, or the symbol for on and off, for several seconds
as a system check. Then, after several more seconds,
the status indicator will light either ON or OFF, or either
the on or off symbol to let you know the status of the
right front passenger’s frontal airbag.Passenger Airbag Status
Indicator – United States
