If you enter the vehicle after a remote start, and the
engine is still running, insert the key into the ignition lock
cylinder and turn it to the RUN position to drive the
vehicle.
Your vehicle’s engine can be started two times using
the transmitter’s remote start feature.
If only one remote start procedure has been done, since
last driving the vehicle or resetting the remote start
system, the engine may be started again remotely
following the remote start procedure a second time.
If the remote start procedure is used again before the
rst ten minute time frame has ended, 10 minutes will be
added to the remaining minutes. The added
10 minutes are considered a second remote start.
The remote vehicle start feature will not operate if:
The remote start system is disabled.
The vehicle’s key is in the ignition.
A door is open or the vehicle’s hood is not closed.
The hazard warning ashers are on.
There is an emission control system malfunction.

Two remote vehicle starts have already been
provided. The maximum number of remote starts or
remote start attempts between ignition cycles
with the key is two.
If a remote start is attempted and is unsuccessful, the
Driver Information Center (DIC) will display REMOTE

can be turned off. See “Content Theft” underDIC
Vehicle Personalization on page 3-71.

This feature delays the locking of the vehicle’s doors for
ve seconds after the last door is closed. Two chimes
will sound when the power door lock switch or the LOCK

Automatic Door Locks
The vehicle’s doors are programmed from the factory to
lock when the shift lever is moved into a forward
gear, and to unlock when the shift lever is moved into
PARK (P).
If someone needs to get in or out of the vehicle after
the doors have been locked, place the shift lever
into PARK (P). You may also unlock all doors using the
power door lock switch or unlock one door using the
inside manual door lock.
If your vehicle has a Driver Information Center (DIC),
there are different programming options for locking and
unlocking the doors automatically. SeeDIC Vehicle

Lockout Protection
The lockout protection feature makes it more difficult to
lock the key in the vehicle. If the driver’s door is
open while the key is in the ignition, the door cannot be
locked with the power door lock switch.

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.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent
alarm system.
A red light located on top of
the instrument panel,
toward the center of the
vehicle and near the
windshield, will ash slowly

The theft-deterrent alarm system needs to be activated
through the Driver Information Center (DIC). See

inDIC Vehicle Personalization on page 3-71. While
armed, the doors will not unlock with the power door lock
switch. The remote alarm will sound if someone
tampers with the trunk, enters the vehicle without using
the remote keyless entry transmitter or key to unlock
the doors, or turns the ignition on without the proper key.
The horn will sound and the headlamps will ash for
up to two minutes. The system will also cut off the fuel
supply, preventing the vehicle from being driven.

Your vehicle may have a Driver Information
Center (DIC).
All messages will appear in the DIC display located in
the instrument panel cluster, below the speedometer.
The DIC buttons are located on the center of the
instrument panel, below the center outlets.
The DIC comes on when the ignition is on. After a short
delay, the DIC on the uplevel vehicle will display the

trip odometers, fuel economy, trip computer, vehicle
system, and compass display information. It also
displays warning messages if a system problem is
detected. In addition, the DIC on the uplevel vehicle
displays phone numbers that are called using the
OnStar
®system, if equipped. SeeOnStar®System on
page 2-34.The outside air temperature automatically appears in
the bottom right corner of the uplevel DIC display when
viewing the trip/odometer screens, fuel screens and
some of the gages screens. If the outside air
temperature is at or below 37°F (3°C), the temperature
reading will toggle between displaying the outside
temperature and the word ICE for two minutes. If there
is a problem with the system that controls the
temperature display, the letters OC (open circuit) or SC
(short circuit) will appear on the display. If this occurs,
have the vehicle serviced by your GM dealer.
The DIC on the uplevel vehicle also allows some
features to be customized or personalized. SeeDIC
Vehicle Personalization on page 3-71for more
information.

The buttons on the uplevel vehicle are the trip/odometer,
set/reset, gages, fuel, and option buttons.
The button functions are detailed in the following pages.
