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.

LDW warnings may occasionally occur due to tar marks,
shadows, cracks in the road, or other road imperfections.
This is normal system operation, the vehicle does not
need service.
LDW Error Message
SERVICE LANE DEPARTURE SYSTEM:This message
may appear in the DIC to indicate that LDW is not
working properly. If this message remains on after
continued driving, the system needs service.
Take your vehicle to your dealer/retailer.
LANE DEPARTURE SYSTEM UNAVAILABLE:
This message may appear in the DIC if LDW does not
activate due to a temporary condition.

How OnStar Service Works
The OnStar system can record and transmit vehicle
information. This information is automatically sent to
an OnStar Call Center when the OnStar button is
pressed, the emergency button is pressed, or if the
airbags or AACN system deploy. This information usually
includes the vehicle’s GPS location and, in the event of
a crash, additional information regarding the crash that
the vehicle was involved in (e.g. the direction from which
the vehicle was hit). When the Virtual Advisor feature of
OnStar Hands-Free Calling is used, the vehicle also
sends OnStar the vehicle’s GPS location so they can
provide services where it is located.
OnStar service cannot work unless the vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless the vehicle is in a place where
the wireless service provider OnStar has hired for that
area has coverage, network capacity and reception when
the service is needed, and technology that is compatible
with the OnStar service. Not all services are available
everywhere, particularly in remote or enclosed areas,
or at all times.Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility
Increase the volume of the radio if the OnStar advisor
cannot be heard. If the light next to the OnStar buttons
is red, the system may not be functioning properly.
Press the OnStar button and request a vehicle
diagnostic. If the light appears clear (no light is
appearing), your OnStar subscription has expired and
all services have been deactivated. Press the OnStar
button to conrm that the OnStar equipment is active.

Detecting the Vehicle Ahead
The vehicle ahead symbol, located next to the FCA
symbol, will only appear when a vehicle ahead of you is
detected in your path. If this symbol does not appear,
or disappears briey, FCA will not respond to vehicles
you may see ahead. The symbol may disappear on
curves, highway exit ramps, or hills. Also, when another
vehicle enters the same lane as you, the FCA system
will not detect the vehicle until it is completely in your
driving lane.
{CAUTION:
When the Adaptive Cruise Control radar is blocked
by snow, ice, or dirt, it may not detect a vehicle
ahead. FCA may not help you avoid a collision
under these conditions. Do not use FCA when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” under
Adaptive Cruise Control on page 3-19.
{CAUTION:
FCA may not detect and warn soon enough to
stationary or slow-moving vehicles or other objects
ahead of you. You could crash into an object ahead
of you. Do not rely on FCA when approaching
stationary or slow-moving vehicles or other objects.
Unnecessary Alerts
FCA may occasionally provide alerts that you consider
unnecessary. It could respond to a turning vehicle
ahead of you, guard rails, signs, and other stationary
objects. This is normal operation, your vehicle does not
need service.

Other Messages
There are three messages that may appear on the
Driver Information Center (DIC). They are CLEAN
RADAR, RADAR CRUISE NOT READY and SERVICE
RADAR CRUISE. SeeDIC Warnings and Messages
on page 3-73.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean
the lens. See “Cleaning the System” underAdaptive
Cruise Control on page 3-19.
Flash-to-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
The ash-to-pass feature will only work with the
headlamps on. It does not work with Daytime
Running Lamps (DRL).
Pull and hold the turn signal lever toward you to use.
If the headlamps are on low beam, pulling the turn signal
towards you will ash the high beams.
Windshield Wipers
Turn the band with the wiper symbol on it to control the
windshield wipers.
8(Mist):For a single wiping cycle, hold it on mist
until the wipers start, then release. The wipers stop after
one wipe. For more wipe cycles, hold the band longer.
6(Delay):Use to set the delay time between wipe
cycles. The wiper speed can be set for a long or short
delay between wipes. The closer the band is set to
the top of the lever, the shorter the delay.
6(Low Speed):For steady wiping at low speed.
1(High Speed):For high-speed wiping.
9(Off):Turns the wipers off.
Clear ice and snow from the wiper blades before
using them. If the wipers are frozen to the windshield,
carefully loosen or thaw them. If they become worn
or damaged, replace with new blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools.
The vehicle has wiper-activated headlamps. After the
windshield wipers have completed eight wipe cycles
within four minutes, the headlamps automatically turn on.
SeeWiper Activated Headlamps on page 3-32for more
information.
3-13

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle
slows down to the previous cruise control speed.
Using Cruise Control on Hills
How well your cruise control works on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you might have to brake or shift to
a lower gear to keep the vehicle’s speed down. Applying
the brake or shifting into a lower gear ends cruise control.
If you need to apply the brake or shift to a lower gear due
to the grade of the downhill slope, you might not want to
attempt to use the cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the cancel button on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
