2005 CADILLAC STS cruise control

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.

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.
Turn the headlamp control from the parking lamp
position to AUTO.
Turn the headlamp control from the headlamp
position to AUTO.

Polarized sunglasses could make the HUD image
harder to see.
As light shines out from the HUD, it is possible for light
to shine back in. In rare occurrences, when the sun
is at a specic angle and position, the sun’s rays can
shine back into the HUD. When this occurs, the display
device within the HUD will be temporarily illuminated.
The event will end when the vehicle’s angle to the
sun changes.
Clean the inside of the windshield as needed to remove
any dirt or lm that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner
on a soft, clean cloth. Wipe the HUD lens gently,
then dry it.
Notice:When cleaning, be careful not to scratch
the HUD or camera lenses. Do not spray glass
cleaner directly on the HUD lens because the
cleaner could leak inside the unit and cause
damage.If the ignition is on and you cannot see the HUD image,
check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the proper height.
Ambient light in the direction your vehicle is facing
is low.
A fuse is blown. SeeFuses and Circuit Breakers on
page 5-95.
Keep in mind that your windshield is part of the HUD
system. SeeWindshield Replacement on page 5-51.
The following Adaptive Cruise Control message
may appear in the HUD:
PEDAL APPLIED ACC OVERRIDE:This message
indicates that you are pressing your foot on the
accelerator pedal and overriding Adaptive Cruise
Control. While you are doing this, the system will not
automatically apply the brakes. Once you remove your
foot from the accelerator pedal, Adaptive Cruise
Control will return to normal operation and be able to
apply the brakes, if needed.
You may also see an Adaptive Cruise Control active
symbol, alert symbol or vehicle ahead symbol. See
Adaptive Cruise Control on page 3-20for more
information.

Cruise Control Light
This light comes on
whenever you set your

The light will go out when the cruise control is turned
off. SeeCruise Control on page 3-16andAdaptive
Cruise Control on page 3-20for more information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Smart Beam Intelligent High-Beam Headlamp
Control System” underHeadlamps on page 3-33and
Headlamp High/Low-Beam Changer on page 3-9
for more information.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It
works only when the
engine is on.
If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound.
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and
do not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before
the gage reads full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may
have indicated that the tank was half full, but
it actually took a little more or less than half the
tank’s capacity to ll the tank.
