CADILLAC STS 2009 1.G Owners Manual

{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 automatically slows your vehicle
down when approaching a slower moving vehicle. It then
adjusts your speed to follow the vehicle in front at the
selected following distance. Your speed increases or
decreases 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
come on. It may feel or sound different than if you were
applying the brakes yourself. This is normal.
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.
3-27

Low-Speed Deactivation
If your speed falls below 25 mph (40 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.
Deactivation When Head-Up Display is
Turned Off
If the HUD is turned off when Adaptive Cruise Control
is engaged, it will begin to disengage. A warning beep
sounds and the message RADAR CRUISE NOT READY
appears on the Driver Information Center (DIC). SeeDIC
Warnings and Messages on page 3-79for 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
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 returns to normal
operation and the brakes can be applied, 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.
3-28

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 might operate differently in a
sharp curve. It might 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 your vehicle could accelerate. When this
happens, the vehicle ahead symbol will not appear
on the HUD.
3-29

Adaptive Cruise Control might detect a vehicle that is
not in your lane and apply the brakes.
Adaptive Cruise Control might 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.
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.
3-30

Using Adaptive Cruise Controls on Hills
and When Towing a Trailer
How well Adaptive Cruise Control works on hills and
while a trailer is being towed depends on your vehicle
speed, vehicle load, traffic conditions, and the steepness
of the hills. It might not detect a vehicle in your lane while
driving on hills. While going up steep hills, you might want
to use the accelerator pedal to maintain your vehicle
speed. While going downhill and towing a trailer, you
might want to brake to keep your vehicle 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
Apply the brake pedal or move the Adaptive Cruise
Control switch to off, to disengage the system. Adaptive
Cruise Control information does not appear on the
HUD while the system is not engaged.
Erasing Set Speed Memory
The set speed memory is erased when the Adaptive
Cruise Control switch or the ignition is turned off.
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 3-79
for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If this happens, turn off the engine and clean the emblem/
lens, located in the center of the front outside grille.
Do not use Adaptive Cruise Control in icy conditions,
or when visibility is low, such as in fog, rain or snow.
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/retailer.

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(Off):Turns off all lamps and automatic lighting
features, including Daytime Running Lamps (DRL) and
IntelliBeam™.
This is a momentary switch that springs back to the
AUTO position when released. An AUTOMATIC LIGHTS
ON message appears on the DIC when automatic lights
are enabled or an AUTOMATIC LIGHTS OFF message
appears on the DIC when the automatic lights are
disabled.AUTO (Automatic):Turns the exterior lamps on and
off automatically depending upon how much light is
outside of the vehicle.
The automatic lights may be disabled even if the control
is in the AUTO position.
To enable automatic lighting do any of the following:
Turn the headlamp control from AUTO to off
and release the switch. It returns back to the
AUTO position by itself.
Turn the headlamp control from the parking lamp
position to AUTO.
Turn the headlamp control from the headlamp
position to AUTO.
To disable automatic lighting do any of the following:
Turn the headlamp control from AUTO to off
and release the switch. It returns back to the
AUTO position by itself.
Turn the headlamp control from AUTO to the
parking lamp position.
Turn the headlamp control from AUTO to the
headlamp position.
Disabling automatic lighting disables the automatic
headlamp operation, DRL, and IntelliBeam™
High-Beams (if the vehicle has them).
3-32

;(Parking Lamps):Turns on the parking lamps
together with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
5(Headlamps):Turns on the headlamps, together
with the previously listed lamps and lights.
IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with IntelliBeam, read this entire section
before using this feature.
IntelliBeam is an enhancement to the vehicle’s
headlamp system. It uses a light sensor located on
the back of the rearview mirror to turn the high-beam
headlamps on and off depending on approaching traffic.
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 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 System, turn the exterior lamp control
to AUTO, with the turn signal/multifunction lever in its
starting position. The High-Beam On Light appears on
the instrument panel cluster when the high-beams are on.
SeeHighbeam On Light on page 3-70. The 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. Vehicles with
IntelliBeam quickly turn off the high-beams if the system
detects the sudden presence of vehicle lights ahead.
3-33

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.
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 is temporarily disabled until the high-beam
stalk is returned to its starting position. If either of
these conditions occur and IntelliBeam already has
the high-beam headlamps on, the feature is disabled
and the 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.
3-34

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.
3-35

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. SeeHeadlamps on page 3-32for
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.
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 3-70for 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.
Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.The DRL system comes on when the following
conditions are met:
It is still daylight and the ignition is on.
The automatic lights are enabled.
The transmission is not in P (Park).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. The 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 the vehicle is started in a dark garage, the
automatic headlamp system comes on immediately.
Once the vehicle leaves 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,
the instrument panel cluster may not be as bright as
usual. Make sure the instrument panel brightness lever
is in the full bright position. SeeInstrument Panel
Brightness on page 3-40.
