CADILLAC DTS 2007 1.G Owners Manual

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.
191

Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your vehicle’s
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 vehicle’s speed. When going
downhill, especially 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,
especially when towing a trailer.
Disengaging Adaptive Cruise Control
To turn off the system, apply the brake pedal,
press the cancel button, or press the Adaptive
Cruise Control button.
Erasing Set Speed Memory
When you press the Adaptive Cruise Control
button or turn the ignition off, the set speed
memory is erased.
Other Messages
There are three additional 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 246for 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, try to
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 your vehicle’s
headlamp system. Using a digital light sensor
on your 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 238.
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).
194

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 167andFlash-to-Pass
on page 172.
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.
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):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 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
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.
Cleaning the IntelliBeam™ Light Sensor
The light sensor is
located on the inside
of the vehicle in front
of the inside 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.
196

Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers are turned
on and have completed eight wipe cycles within
four minutes.
When the ignition is turned to OFF, the
wiper-activated headlamps immediately turn off.
The wiper-activated headlamps also turn off if the
windshield wipers are 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.
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 exterior lamp control is in the off position.
The transaxle is not in PARK (P)
(United States only).
The light sensor is covered or not detecting
light. See “Sensors” underDual Climate Control
System on page 210.
When DRL are on, no other exterior lamps such as
the parking lamps, taillamps, etc. will be on when
the DRL are being used. Your instrument panel will
not be lit up either.
197

When automatic lighting is on and it is dark enough
outside, the turn signal lamps will turn off and
normal low-beam headlamp operation will occur.
When automatic lighting is on and it is bright
enough outside, the regular lamps will go off, and
the DRL will take over. 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 approximately one minute for
the automatic headlamp system to change to DRL
if there is light outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
knob is in the full bright position. SeeInstrument
Panel Brightness on page 199.
Turning on automatic lighting or the headlamps
will deactivate the DRL. If the parking lamps or the
fog lamps were turned on instead, the DRL will
still deactivate.
To idle your vehicle with the DRL off at night,
turn off automatic lighting and shift the transaxle
into PARK (P). Placing your vehicle in PARK (P)
disables the DRL. The DRL will stay off until you
shift out of PARK (P).To drive your vehicle with the DRL off, turn off
automatic lighting and manually turn on the parking
lamps or fog lamps (if equipped).
As with any vehicle, you should turn on the
regular headlamp system when you need it.
Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions.
-(Fog Lamps):The fog lamps button is
located on the exterior lamps control. The exterior
lamps control is located on the instrument panel
to the left of the steering column.
The ignition must be on for the fog lamps to work.
Press the exterior lamps button to turn the
fog lamps on or off. A light will come on in the
instrument panel cluster when the fog lamps
are in use.
When the headlamps are changed to high-beam,
the fog lamps will turn off. The fog lamps come
back on again when the high-beam headlamps
are turned off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
198

Cornering Lamps
The cornering lamps come on when the
headlamps or parking lamps are on and you
signal a turn with the multifunction lever.
They provide more light for cornering.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have
been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is
turned to OFF. This protects against draining
the battery in case you have accidentally left the
headlamps or parking lamps on. The battery saver
does not work if the headlamps are turned on
after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to
turn the lamps back on.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The button for this control is located below the
exterior lamps control.
Push the button in and release to extend the button.
Turn the button clockwise for brightness of the
instrument panel lights and counter clockwise to
turn the brightness down.
Courtesy Lamps
The courtesy lamps are located on the headliner
above the rear seat. These lamps come on by
turning the instrument panel brightness knob fully
clockwise or when any door is opened and it is
dark outside. Puddle lamps are located on
the bottom of the front and rear door trim.
Professional vehicles have an additional dome
lamp and also opera lamps.
199

Entry Lighting
This feature turns on the courtesy lamps and the
backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press
the remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the entry
lighting system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn
on. The courtesy lamps turn off approximately
25 seconds after the last door is closed. They will
dim to off if the ignition key is turned to RUN, or
immediately deactivate if the power locks are
activated.
Parade Dimming
This feature prohibits dimming of the digital
displays and backlighting during daylight hours
when the key is in the ignition and the headlamps
are on. This feature is fully automatic. When
the light sensor reads darkness outside and the
parking lamps are active, the digital displays
can be adjusted by turning the instrument panel
brightness knob counterclockwise to dim and
clockwise to brighten lighting.
Reading Lamps
The reading lamps are located on the overhead
console on the headliner and in the rear door
opening. These lamps come on automatically
when any door is opened and it is dark outside.
For manual operation, press the button to
turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
Battery Load Management
The battery load management feature is
designed to monitor the vehicle’s electrical
load and determine when the battery is in a
heavy discharge condition. During times of high
electrical loading, the engine may idle at a higher
revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear
window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.
