{Warning
Leaving children in a vehicle with a
remote key is dangerous and children or
others could be seriously injured or killed.
They could operate the power windows
or other controls or make the vehicle
move. The windows will function with
the remote key in the vehicle, and
children or others could be caught in the
path of a closing window. Do not leave
children in a vehicle with a remote key.

Disarming the Alarm System
To disarm the alarm system or turn off the
alarm if it has been activated, do one of the
following:
.PressKon the remote key.
.Unlock the vehicle using the Keyless
Access system.
.Start the vehicle.
To avoid setting off the alarm by accident:
.Lock the vehicle after all occupants have
left the vehicle and both doors are closed.
.Always unlock a door with the remote
key or use the Keyless Access system.
Unlocking the driver door with the key will
not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
IfKis pressed on the remote key and the
horn chirps and the lights flash three times,
a previous alarm occurred while the system
was armed.
If the alarm has been activated, a message
will appear on the DIC.
Inclination Sensor and Intrusion Sensor
In addition to the standard theft-deterrent
system features, this system may also have
an inclination sensor and intrusion sensor.
The inclination sensor can activate the alarm
if it senses movement of the vehicle, such
as a change in vehicle orientation.
The intrusion sensor monitors the vehicle
interior, and can activate the alarm if it
senses unauthorized entry into the vehicle’s
interior. Do not allow passengers or pets to
remain in the vehicle when the intrusion
sensor is activated.
Before arming the theft-deterrent system
and activating the intrusion sensor:
.Make sure both doors and windows are
completely closed.
.Secure any loose items such as
sunshades.
.Make sure there are no obstructions
blocking the sensors.
Intrusion and Inclination Sensors Disable
Switch
It is recommended that the intrusion and
inclination sensors be deactivated if pets are
left in the vehicle or if the vehicle is being
transported. When the roof panel is off, or the
convertible top is down, the intrusion
system is turned off.
With the vehicle turned off, press
oon the
overhead console, next to OnStar. The
indicator light will display momentarily,
indicating that these sensors have been
disabled until the next time the alarm
system is armed.
Immobilizer
See Radio Frequency Statement 0316.
Immobilizer Operation
The vehicle has a passive theft-deterrent
system.
The security light comes on in the
instrument cluster if there is a problem with
arming or disarming the theft-deterrent
system. This light also comes on briefly
when the engine is started.

24 Keys, Doors, and Windows
The system is automatically armed when
the ignition is turned off.
The immobilization system is disarmed
when the ignition is turned on or placed in
ACC/ACCESSORY and a valid remote key is
found in the vehicle.
You do not have to manually arm or disarm
the system.
The system has one or more remote keys
that are matched to an immobilizer control
unit in the vehicle. Only a correctly matched
remote key starts the vehicle. The vehicle
may not start if the remote key is damaged.
If the engine does not start and the security
light comes on, there may be a problem
with the immobilizer system. Try starting
the vehicle again.
If the vehicle does not start and the remote
key appears to be undamaged, try another
remote key. Or, place the remote key in the
cupholder backup location. SeeRemote
Keyless Entry (RKE) System Operation 07.
If the engine still does not start with the
other remote key, or with the remote key in
the cupholder backup location, the vehicle
needs service. If the engine does start, the first remote key may be faulty. See your
dealer or have a new remote key
programmed to the vehicle.
The immobilizer system can learn new or
replacement remote keys. Up to eight
remote keys can be programmed for the
vehicle. To program additional remote keys,
see
“Programming Remote Keys to the
Vehicle” underRemote Keyless Entry (RKE)
System Operation 07.
Do not leave the remote key or device that
disarms or deactivates the theft-deterrent
system in the vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things, like
other vehicles, look farther away than
they really are. If you cut too sharply
into the right lane, you could hit a
vehicle on the right. Check the inside
mirror or glance over your shoulder
before changing lanes. The passenger side mirror is convex shaped.
A convex mirror's surface is curved so more
can be seen from the driver seat.
Power Mirrors
To adjust each mirror:
1. Press
}or|to select the driver or
passenger side mirror. The indicator light
will illuminate.
2. Press the arrows on the control pad to move the mirror in the desired position.
3. Adjust each outside mirror so that a little of the vehicle and the area behind it can
be seen.
4. Press
}or|again to deselect the
mirror.

Instruments and Controls 91
Tire Pressure Light
For vehicles with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the engine is started. It provides
information about tire pressures and
the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires
are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display. Stop as
soon as possible, and inflate the tires to the
pressure value shown on the Tire and
Loading Information label. SeeTire Pressure
0 267.
When the Light Flashes First and Then Is On
Steady
If the light flashes for about a minute and
then stays on, there may be a problem with
the TPMS. If the problem is not corrected, the light will come on at every ignition
cycle. See
Tire Pressure Monitor Operation
0 270.
Engine Oil Pressure Light
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
This light should come on briefly as the
engine is started. If it does not come on,
have the vehicle serviced by your dealer. If the light comes on and stays on, it means
that oil is not flowing through the engine
properly. The vehicle could be low on oil
and may have some other system problem.
See your dealer.
Security Light
The security light should come on briefly as
the engine is started. If it does not come on,
have the vehicle serviced by your dealer.
If the system is working normally, the
indicator light turns off.
If the light stays on and the engine does
not start, there could be a problem with the
theft-deterrent system. See
Immobilizer
Operation 023.
