2010 CHEVROLET EXPRESS engine

{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
right front 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.
SeeVehicle Data Recording and Privacy on
page 8-18andEvent Data Recorders on page 8-18.
•Let only qualified technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.

Remote Vehicle Start
Your vehicle may have a remote start feature. This
feature allows you to start the engine from outside the
vehicle. It may also start the vehicle’s heating or air
conditioning systems. SeeClimate Control System on
page 4-15for additional information.
Laws in some local communities may restrict the use of
remote starters. For example, some laws may require
a person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range
of operation. However, the range may be less while the
vehicle is running.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 3-4for additional
information.
/(Remote Vehicle Start):This button will be on the
RKE transmitter if you have remote start.
To start the engine using the remote start feature:
1. Aim the RKE transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the remote
vehicle start button for four seconds or until the
vehicle’s turn signal lamps flash.
When the vehicle’s engine starts, the parking lamps
will turn on and remain on while the engine is
running. The vehicle’s doors will be locked. The
airbag readiness light will be on during a remote
start. It should turn off when the ignition is turned to
ON/RUN. SeeAirbag Readiness Light on
page 4-23for more information.
3. If it is the first remote start since the vehicle has been
driven, repeat these steps, while the engine is still
running, to extend the engine running time by
10 minutes. Remote start can be extended one time.
After entering the vehicle during a remote start, insert
and turn the key to ON/RUN to drive the vehicle.
After a remote start, the engine will automatically shut
off after 10 minutes unless a time extension has
been done or the vehicle’s key is inserted into the
ignition switch and turned to ON/RUN.
3-7

The maximum number of remote starts between ignition
cycles with the key is two.
If the remote start procedure is used again before the
first 10 minute time frame has ended, the first
10 minutes will immediately expire and the second
10 minute time frame will start.
After your vehicle’s engine has been started two times
using the remote start button, the vehicle’s ignition
switch must be turned to ON/RUN and then back to
LOCK/OFF using the key before the remote start
procedure can be used again.
To manually shut off the engine after a remote start:
•Aim the RKE transmitter at the vehicle and
press the remote start button until the parking lamps
turn off.
•Turn on the hazard warning flashers. SeeHazard
Warning Flashers on page 4-3.
•Insert the vehicle’s key into the ignition switch and
turn the switch to ON/RUN and then back to
LOCK/OFF.The remote vehicle start feature will not operate if:
•The remote start system is disabled through
the DIC.
•The vehicle’s key is in the ignition.
•The vehicle’s hood is open
•The hazard warning flashers are on.
•There is an emission control system malfunction.
SeeMalfunction Indicator Lamp on page 4-30.
•The engine coolant temperature is too high.
•The oil pressure is low.
•Two remote vehicle starts have already been

PASS-Key®III+ Electronic
Immobilizer
SeeRadio Frequency Statement on page 8-20for
information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry and Science Canada.
PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle is equipped with the PASS-Key®III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III+ is a passive
theft deterrent system.
The system is automatically armed when the key is
removed from the ignition.
You do not have to manually arm or disarm the system.The security light will come on if there is a problem with
arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it shuts down the vehicle’s
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. Anyone
using a trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
If the engine does not start and the security message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the instrument panel PASS
KEY fuse. If the engine still does not start with the
other key, your vehicle needs service. If your vehicle
does start, the first key may be faulty. See your
dealer/retailer or a locksmith who can service the
PASS-Key
®III+ to have a new key made. SeeFuses
and Circuit Breakers on page 6-110.
3-20

It is possible for the PASS-Key®III+ decoder to learn
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle. This
procedure is for learning additional keys only. If all the
currently programmed keys are lost or do not operate,
you must see your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to have keys made and
programmed to the system.
See your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
To program the new key:
1. Verify the new key has
1stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder and start the engine. If the
engine will not start, see your dealer/retailer
for service.3. After the engine has started, turn the key to
LOCK/OFF and remove the key.
4. Insert the key to be programmed and turn it to
ON/RUN within 10 seconds of removing the
previous key.
The security message will turn off once the key has
been programmed. It may not be apparent that
the security message went on due to how quickly
the key is programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you lose or damage a PASS-Key
®III+ key, see your
dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
