CADILLAC STS 2005 1.G Owners Manual

If this symbol does not appear, or disappears briey,
Adaptive Cruise Control will not respond to vehicles
you may see ahead.
{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. Adaptive Cruise Control may
not have time to slow your vehicle enough to
avoid a collision. Do not use Adaptive Cruise
Control when the radar is blocked by snow,
ice, or dirt. Keep your radar clean. See
“Cleaning the System” later in this section.Adaptive Cruise Control will, automatically, slow your
vehicle down when approaching a slower moving
vehicle. It will then adjust your speed to follow the
vehicle in front at the selected follow distance. Your
speed will increase or decrease to follow the vehicle in
front of you but will not exceed the set speed. It
may apply limited braking, if necessary. When braking is
active, your brake lights will come on. It may feel or
sound different than if you were applying the brakes
yourself. This is normal.
3-27

Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. You could crash
into an object ahead of you. Do not use
Adaptive Cruise Control when approaching
stationary or slow-moving vehicles or other
objects.
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. Your vehicle may
accelerate toward objects, such as a stopped
vehicle that suddenly appears after the lead
vehicle changes lanes. Your complete attention
is always required while driving and you
should be ready to take action and apply the
brakes.
Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, Adaptive Cruise Control will
begin to disengage. The driver alert symbol on the HUD
will ash and the warning beep will sound. The driver
must take action since Adaptive Cruise Control will
not slow the vehicle to a stop.
3-28

Deactivation When Head-Up Display is
Turned Off
If you turn the HUD off when Adaptive Cruise Control is
engaged, it will begin to disengage. A warning beep will
sound and the message RADAR CRUISE NOT READY
will appear on the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 3-78for
additional information. If Adaptive Cruise Control was
braking when the HUD is turned off, the braking will
continue briey.
Passing a Vehicle/Adaptive Cruise Control
Override
If you need to increase speed to pass a vehicle, use the
accelerator pedal. While you are doing this, the
system will not automatically apply the brakes. A PEDAL
APPLIED ACC OVERRIDE message will appear on
the HUD. SeeHead-Up Display (HUD) on page 3-43for
additional information. Once you pass the vehicle and
remove your foot from the accelerator pedal, Adaptive
Cruise Control will return to normal operation and
be able to apply the brakes, if needed.
{CAUTION:
If you rest your foot on the accelerator pedal,
the system will not automatically apply the
brakes. You could crash into a vehicle ahead
of you. Do not rest your foot on the accelerator
pedal when using Adaptive Cruise Control.
3-29

Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle
in your lane. You could crash into a vehicle
ahead of you, or lose control of your vehicle.
Give extra attention in curves and be ready to
use the brakes if necessary. Select an
appropriate speed while driving in curves.
Adaptive Cruise Control may operate differently in a
sharp curve. It may reduce your speed if the curve is
too sharp.When following a vehicle and entering a curve, Adaptive
Cruise Control could lose track of the vehicle in your
lane and accelerate your vehicle. When this happens,
the vehicle ahead symbol will not appear on the HUD.
3-30

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 on exit ramps.
3-31

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 the steepness 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 3-78for more information.
3-32

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.
Headlamps
The exterior lamp control is located in the middle of the
turn signal/multifunction lever.
O(Exterior Lamp Control):Turn the control with this
symbol on it to operate the exterior lamps.The exterior lamp control has four positions:
O(On/Off):Turn the control to this position to turn off
all lamps and automatic lighting features including
Daytime Running Lamps and Intellibeam™
This is a “momentary” switch that will spring back to the
AUTO position when released. An AUTOMATIC
LIGHTS ON message will appear on the DIC when
automatic lights are enabled or an AUTOMATIC LIGHTS
OFF message will appear on the DIC when the
automatic lights are disabled.
AUTO (Automatic):Turn the control to this position to
put the headlamps in automatic mode. AUTO mode, if
enabled, will turn the exterior lamps on and off depending
upon how much light is available outside of the vehicle.
Due to the “momentary” switch design, your automatic
lights may be disabled even if you are in AUTO position.
To enable automatic lighting do any of the following:
Turn the headlamp control from AUTO to off
and release the switch. It will return back to
the AUTO position by itself.

listed lamps and lights.
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 your vehicle’s
headlamp system. Using a digital light sensor on your
rearview mirror, this system will turn the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The Intellibeam™ system will turn your 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™
O(On/Off):Quickly press and release the on/off
button on the inside rear view mirror. The indicator on
the mirror will ash once to let you know the system has
been turned on. Once the system has been turned
on, it will remain on each time the vehicle is started.
Additionally, the Intellibeam™ system must be enabled.
3-34

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
will appear on the instrument panel cluster when
the high-beams are on. SeeHighbeam On Light on
page 3-72. Your vehicle is equipped with variable
intensity high-beams. The high-beam indicator on the
instrument panel will illuminate as soon as the
high-beams start to come on, and will remain on until
the high-beams have completely turned off. All
Intellibeam™ equipped vehicles, however, will quickly
turn off the high-beams if the system detects the sudden
presence of vehicle lights ahead.
Driving with Intellibeam™
Intellibeam™ will only activate your high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps will 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.
The high-beam headlamps are manually turned on
or you use the ash-to-pass feature. SeeHeadlamp
High/Low-Beam Changer on page 3-9and
Flash-to-Pass on page 3-13.
When either of these conditions occur, the
Intellibeam™ feature will be temporarily disabled
until the high-beam stalk is returned to the neutral
position.
The exterior lamp control is turned to any setting
except AUTO.
When this occurs, Intellibeam™ will be disabled
until the control is turned back to the AUTO position
and the AUTOMATIC LIGHTS ON message is
displayed 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.
3-35

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 may 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 and reset to the original
factory setting by using the controls on the inside
rearview mirror.
O(On/Off):To disable the system, press and hold
this button on the inside rearview mirror for three
seconds and release it after the indicator on the inside
rearview mirror ashes two times. This lets you
know that Intellibeam™ has been turned off and will not
come back on until the system has been reset.
To reset the system, quickly press and release this
button on the inside rearview mirror. The indicator on the
inside rearview mirror will ash one time to indicate
that Intellibeam™ has been reset.
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
will automatically be reset each time the ignition
is turned off and then on again; otherwise, refer to the
text above for resetting the system.
