Additional Factors Affecting System
Operation
Safety belts help keep the passenger in position on the
seat during vehicle maneuvers and braking, which
helps the passenger sensing system maintain the
passenger airbag status. See “Safety Belts” and “Child
Restraints” in the Index for additional information
about the importance of proper restraint use.
A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
We recommend that you not use seat covers or other
aftermarket equipment except when approved by GM for
your specic vehicle. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-67for more
information about modications that can affect how the
system operates.
{CAUTION:
Stowing of articles under the passenger seat or
between the passenger seat cushion and seatback
may interfere with the proper operation of the
passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-16.
{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inate during improper service. You can be injured
if you are close to an airbag when it inates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualied to do so.

Remote Vehicle Start
Your vehicle may have a remote starting feature that
allows you to start the engine from outside the vehicle.
It may also start the vehicle’s heating or air conditioning
systems and rear window defogger. When the remote
start system is active and the vehicle has an automatic
climate control system, it will automatically regulate
the inside temperature. Normal operation of these
systems will return after the ignition key is turned to
ON/RUN.
Laws in some 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 2-3for additional
information.
/(Remote Start):This button will be on the RKE
transmitter if you have remote start.
To start the vehicle using the remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the transmitter’s
remote start button for about four seconds or
until the vehicle’s turn signal lamps ash. The doors
will lock.
When the vehicle starts, the parking lamps turn on
and remain on while the engine is running.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time, or one start with a time extension. The
rst start must expire or be canceled to get two separate
10 minute starts.
If it is the rst remote start since the vehicle has been
driven, repeat the previous steps, while the engine is still
running, to extend the engine running time by 10 minutes
from the time you repeat the steps for remote starting.
The remote start running time can be extended one time
and only after the rst remote start.
After entering the vehicle during a remote start, insert
and turn the key to ON/RUN to drive the vehicle.
2-7

The engine will shut off automatically 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.
To manually shut off a remote start, do any of the
following.
Aim the RKE transmitter at the vehicle and press
and release the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch out of LOCK/OFF position
and then back to LOCK/OFF.
The parking lamps turn off to indicate the engine is off.
After the engine has been started two times, or one
time with a time extension, the vehicle’s ignition must be
turned to ON/RUN using the key before the remote
start procedure can be used again. SeeIgnition
Positions on page 2-21for information regarding the
ignition positions on your vehicle.
The remote vehicle start feature will not operate if any
of the follow occur:
The remote start system is disabled through the DIC.
The vehicle’s key is in the ignition.
A door on the vehicle is open.

Indicator Lamp on page 3-40
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts, or one start with a time
extension, have already been provided for that
ignition cycle.
If a remote start is attempted and is unsuccessful, the
Driver Information Center (DIC) will display REMOTE
START DISABLED.
Vehicles that have the remote start feature are shipped
from the factory with the remote vehicle start system
enabled. The system may be enabled or disabled
through the DIC. See “REMOTE START” underDIC
Vehicle Personalization on page 3-74for additional
information. If your vehicle does not have the DIC
feature, and remote vehicle start was installed at the
dealer/retailer, you will need to have the dealer/retailer
enable or disable the system.
2-8

If the vehicle has the content theft-deterrent system, the
vehicle is programmed to arm the system with the
power door lock switch. If your vehicle has a Driver
Information Center (DIC) this feature can be turned off.
See “Content Theft” underDIC Vehicle Personalization
on page 3-74.
Delayed Locking

unlock when the shift lever is moved into PARK (P).
On vehicles with a Driver Information Center (DIC), there
are different programming options for unlocking the
doors automatically. SeeDIC Vehicle Personalization on
page 3-74.

This feature cannot guarantee that you will never be
locked out of the vehicle. If the key is not left in
the ignition, or, if the manual door lock is used, the key
could still be locked inside the vehicle. Always
remember to take the key with you.
