Automatic Dimming Rearview Mirror
The vehicle has an automatic dimming rearview
mirror with a compass display. The mirror may also
have OnStar
®controls and/or Intellibeam™. For more
information on OnStar, seeOnStar®System on
page 2-49. For more information on Intellibeam™ see
“Intellibeam Intelligent High-Beam Headlamp Control
System” underExterior Lamps on page 3-32.
O(On/Off):If the vehicle has this button, press to
turn the automatic dimming feature on or off.
Automatic Dimming Mirror Operation
Automatic dimming reduces the glare of lights from

Compass Calibration
If the letter C should ever appear in the compass
display window, the compass may need to be calibrated.
If the correct compass direction does not show on the
display, there may be a strong magnetic eld interfering
with the compass, such as a magnetic antenna
mount, magnetic note pad holder or a similar magnetic
item. Remove the interference and calibrate the
compass, if calibrating is needed.
The compass can be placed in calibration mode
manually by pressing and holding AUTO

depending on the vehicle, until a C is shown in the
compass display.
To calibrate, drive the vehicle in a small circle slowly
until the display reads the correct direction.

Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete. If you momentarily press and release the
lever, the turn signal will ash 3 times.
An arrow on the instrument
panel cluster and in the
outside rearview mirror will
ash in the direction of
the turn or lane change.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane
change is complete. The lever returns when it is
released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON after driving about a mile to remind
you to turn it off. SeeDIC Warnings and Messages
on page 3-75.Arrows that ash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers will not see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. SeeRear
Underseat Fuse Block on page 5-104.
Headlamp High/Low-Beam Changer
Push forward to change the headlamps from low
beam to high. Pull the lever back and then release
it to change from high beam to low.
This light on the instrument
panel cluster will be on,
indicating high-beam
usage.

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 3-75.
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
You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers stop after one wipe. For more wipe
cycles, hold the band longer on mist.
6(Delay):Turn the band to choose 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):Turn the band away from you to
the rst solid band past the delay settings for steady
wiping at low speed.
1(High Speed):For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entire
section before using it.
IntelliBeam is an enhancement to the vehicle’s
headlamp system. Using a digital light sensor on the
rearview mirror, this system turns the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam system turns the high-beam headlamps
on when it is dark enough, there is no other traffic
present, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam button on the inside
rear view mirror. The IntelliBeam indicator on the
mirror turns on to indicate the system is on. Once the
system has been turned on, it remains on each time the
vehicle is started, but the IntelliBeam system must be
enabled.
To enable the IntelliBeam system, turn the exterior lamp
control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On Light
appears on the instrument panel cluster when the
high-beams are on. SeeHighbeam On Light on
page 3-69.
Driving with IntelliBeam™
IntelliBeam only activates the high-beams when driving
over 20 mph (32 km/h).
The high-beam headlamps remain on, under the
automatic control of IntelliBeam, until any of the
following situations occur:
The system detects an approaching vehicle’s
headlamps.
The system detects a preceding vehicle’s taillamps.
The outside light is bright enough that high-beam
headlamps are not required.
The vehicle’s speed drops below 15 mph (24 km/h).
The headlamp stalk is moved forward to the
high-beam position or the ash-to-pass feature is
used. SeeHeadlamp High/Low-Beam Changer
on page 3-9andFlash-to-Pass on page 3-13.
When either of these conditions occur, the
IntelliBeam feature is disabled and the IntelliBeam
light in the mirror turns off until the high-beam stalk is
returned to the neutral position.
If IntelliBeam was using low-beams prior to this
action, the IntelliBeam feature is temporarily
disabled until the stalk is returned to the neutral
position.
3-33

The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam is disabled until the
control is turned back to the AUTO position.
The IntelliBeam system is turned off at the inside
rearview mirror.
IntelliBeam might not turn off the high-beams if the
system cannot detect other vehicle’s lamps because of
any of the following:
The other vehicle’s lamp(s) are missing, damaged,
obstructed from view, or otherwise undetected.
The other vehicle’s lamp(s) are covered with dirt,
snow, and/or road spray.
The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,
mist, or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked, or
obstructed by something that blocks the view of the
IntelliBeam light sensor.
Your vehicle’s windshield is covered with ice, dirt,
haze, or other obstructions.
Your vehicle is loaded such that the front end of the
vehicle points upward, causing the IntelliBeam
sensor to aim high and not detect headlamps and
taillamps.
You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
Disabling and Resetting IntelliBeam™ at
the Rearview Mirror
IntelliBeam can be disabled by using the controls on the
inside rearview mirror.
AUTO
3(On/Off):Press this button on the inside
rearview mirror to disable the system. The IntelliBeam
indicator turns off and does not come back on until
the IntelliBeam button is pressed again.
When IntelliBeam has turned on the high-beams, pull or
push the high-beam stalk. This will disable IntelliBeam.
The IntelliBeam indicator on the mirror turns off. To
turn IntelliBeam back on, press the IntelliBeam button
on the mirror.
A different sensitivity setting is available for dealer/
retailer diagnostics. This is done by pushing and holding
this button for 20 seconds until the IntelliBeam indicator
light ashes three times. If you accidentally activate
this, the vehicle’s setting automatically is reset when the
ignition is turned off and then on again.
