2007 CADILLAC STS Owners Manual

Adaptive Cruise Control may detect a vehicle that
is not in your lane and apply the brakes.
Adaptive Cruise Control may, occasionally,
provide a driver alert and/or braking that you
consider unnecessary. It could respond to signs,
guardrails and other stationary objects when
entering or exiting a curve. This is normal
operation. Your vehicle does not need service.
Highway Exit Ramps
{CAUTION:
Adaptive Cruise Control may lose track of
the vehicle ahead and accelerate up to
your set speed while entering or on
highway exit ramps. You could be startled
by this acceleration and even lose control
of the vehicle. Disengage Adaptive Cruise
Control before entering a highway exit
ramp. Do not use Adaptive Cruise Control
while entering or on exit ramps.
209

Other Vehicle Lane Changes
If another vehicle enters the same lane as you,
Adaptive Cruise Control will not detect the vehicle
until it is completely in the lane. Be ready to
take action and apply the brakes yourself.
Using Adaptive Cruise Controls on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your
speed, vehicle load, traffic conditions and thesteepness of the hills. It may not detect a vehicle
in your lane while driving on hills. When going
up steep hills, you may want to use the accelerator
pedal to maintain your speed. When going
downhill when towing a trailer, you may want to
brake to keep your speed down. Applying the
brake disengages the system. You may choose
not to use Adaptive Cruise Control on steep
hills when towing a trailer.
Disengaging Adaptive Cruise Control
To disengage the system, apply the brake pedal
or move the Adaptive Cruise Control switch to
off. Adaptive Cruise Control information will
not appear on the HUD when the system is not
engaged.
Erasing Set Speed Memory
When you turn the Adaptive Cruise Control switch
or the ignition off, the set speed memory is erased.

Other Messages
There are three messages that may appear on the
DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN
RADAR. These messages will appear to indicate
a problem with the Adaptive Cruise Control.
SeeDIC Warnings and Messages on page 264
for more information.
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. Remember, do not use Adaptive
Cruise Control in icy conditions, or when visibility is
low, such as in fog, rain or snow.
The emblem/lens is located in the center of
the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens,
engage the Adaptive Cruise Control. If you are
unable to do so, see your dealer.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
If your vehicle has 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
located on the back of the rearview mirror,
this system turns the 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™
AUTO3(IntelliBeam™ On/Off):Press
and release the IntelliBeam™ button on the inside
rear view mirror. The IntelliBeam™ indicator on
the mirror turns on. Once the system has
been turned on, it remains on each time the
vehicle is started. Additionally, 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 257. Your
vehicle has variable intensity high-beams.
The high-beam indicator on the instrument panel
cluster comes on as soon as the high-beams
start to come on, and remains on until the
high-beams have completely turned off. All
vehicles that have IntelliBeam™, however, quickly
turn off the high-beams if the system detects
the sudden presence of vehicle lights ahead.
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
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.
213

The high-beam headlamps are manually
turned on or you use the ash-to-pass feature.
SeeHeadlamp High/Low-Beam Changer on
page 183andFlash-to-Pass on page 188.
When either of these conditions occur,
the IntelliBeam™ feature is temporarily
disabled until the high-beam stalk is returned
to the neutral position. If either of these
conditions occur and IntelliBeam™ already
has the high-beam headlamps on, the
IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off.
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 and the AUTOMATIC LIGHTS
ON message displays on the DIC.
The IntelliBeam™ system is turned off at the
inside rearview mirror.
The vehicle’s speed drops below
15 mph (24 km/h).IntelliBeam™ may not turn off the high-beams if
the system cannot detect other vehicle’s lamps
because of any of the following:
The others 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.
214

Disabling and Resetting IntelliBeam™ at
the Rearview Mirror
IntelliBeam™ can be disabled and reset to the
original factory setting by using the controls on the
inside rearview mirror.
AUTO
3(IntelliBeam™ On/Off):To disable the
system, press this button on the inside rearview
mirror. 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 disables
IntelliBeam™ and the IntelliBeam™ indicator
on the rearview mirror turns off. To re-enable
IntelliBeam™, press the IntelliBeam™ button on
the mirror.
A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding
this button for 20 seconds until the light ashes
three times. If you accidentally activate this, the
vehicle’s setting automatically resets each time the
ignition is turned off and then on again; otherwise,
refer to the text above for resetting the system.
Cleaning the IntelliBeam™ Light Sensor
The light sensor is
located on the inside of
the vehicle at the back of
the rearview mirror.
Clean the light sensor window, periodically, using
glass cleaner on a soft cloth. Gently wipe the
sensor window. Do not spray glass cleaner directly
on the surface of the sensor window.
Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers have been in
use for about six seconds. For this feature to work,
automatic lighting must be enabled. See
Headlamps on page 211for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also
turn off if the windshield wiper control is turned off.
215

Headlamps on Reminder
A warning chime will sound if the exterior lamp
control is left on in either the headlamp or parking
lamp position and the driver’s door is opened
with the ignition off. SeeLights On Reminder on
page 256for additional information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.
The DRL system will make the turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is on,
the automatic lights are enabled, and
the transmission is not in PARK (P).
When DRL are on, only your front turn signal
lamps will be on. No other exterior lamps will be
on when the DRL are being used. Your instrument
panel will not be lit.When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the
low-beam headlamps will turn on. When it is bright
enough outside, the low-beam headlamps will go
off, and the DRL will turn back on. If you start your
vehicle in a dark garage, the automatic headlamp
system will come on immediately. Once you leave
the garage, it will take about one minute for the
automatic headlamp system to change to DRL if it
is light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make
sure your instrument panel brightness lever is in the
full bright position. SeeInstrument Panel Brightness
on page 220.
To operate your vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.
