Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
Valet Lockout Switch
The valet lockout switch
is located inside the
glove box.
9(Off):Press this side of the button to turn the
lockout feature off. When the lockout feature is off,
you can open the trunk using either the keyless entry
transmitter or the trunk release button located near
the headlamp switch on the instrument panel.
— (On):Press this side of the button to turn the lockout
feature on. When the lockout feature is turned on,
the trunk cannot be unlocked with the keyless entry
transmitter or the trunk release button located near the
headlamp switch on the instrument panel.
If the valet lockout feature is on it will also disable the
Universal Home Remote transmitter, if equipped.
Locking the glove box with your key will also help to
secure your vehicle.
SeeRemote Keyless Entry (RKE) System Operation
on page 2-5andTrunk on page 2-13for additional
information.

mirror with a compass display. The mirror may also

High-Beam Headlamp Control System” underExterior
Lamps on page 3-29. For more information about
OnStar
®, seeOnStar®System on page 2-51.

heading. The compass automatically calibrates as the
vehicle is driven.
Compass Calibration
If after a few seconds, the display does not show the
correct direction, (for example, N for North), there
may be a strong magnetic eld interfering with the
compass. Interference can be caused by a magnetic
antenna mount, magnetic note pad holder or a
similar magnetic item.

How the System Works
LDW uses a camera located between the inside rearview
mirror and the windshield to detect the lane markings.
@(Lane Departure Warning):To turn LDW on and off,
press the LDW control, located by the exterior headlamp
control. An indicator on the control will light to indicate
that LDW is on.
When the vehicle is started, the LDW symbol, located in
the instrument panel cluster, will briey come on to
indicate that the light is operational.LDW only operates at speeds of 35 mph (56 km) or
greater. If LDW is turned on when traveling at these
speeds, the LDW symbol will appear green if the system
detects a left or right lane marking. This symbol will
change to amber and ash and three beeps will sound if
you cross a detected lane marking without using the
turn signal.
If the LDW symbol does not appear, LDW is not currently
operating and will not warn you.
To change the volume of the warning chime, see Chime
Volume underDIC Vehicle Customization on page 3-86
for more information.
When the System Does Not Seem To
Work Properly
The LDW symbol will not appear when the system is
having difficulty seeing the lines on the road or if
the view of the camera on the windshield is blocked
with mud, dirt, snow, ice, or slush, if the windshield
is damaged, or when weather limits visibility, such as
while driving in fog, rain, or snow conditions. This is
normal operation, the vehicle does not need service.
For cleaning instructions, seeWashing Your Vehicle
on page 5-90.
