2008 CADILLAC DTS warning

To set Adaptive Cruise Control, do the following:
1. Press the
](On) button.
2. Get up to the speed desired.
3. Press in the SET– button and release it.
4. Take your foot off the accelerator pedal.
Once Adaptive Cruise Control is set, it may immediately
apply the brakes if it detects a vehicle ahead is too
close or moving slower than your vehicle.
The on symbol is located on the display at the top of
the instrument panel to the right of the driver. When
the on symbol is lit on the display, it indicates that
Adaptive Cruise Control is active.
A message on the DIC will also display when Adaptive
Cruise Control is set. SeeDIC Warnings and
Messages on page 3-75.
Keep in mind speed limits, surrounding traffic speeds,
and weather conditions when adjusting your set speed.
If your vehicle is in Adaptive Cruise Control when
the traction control system begins to limit wheel spin,
the Adaptive Cruise Control will automatically disengage.
SeeTraction Control System (TCS) on page 4-5and
StabiliTrak
®System on page 4-7. When road conditions
allow you to safely use it again, you may turn the
Adaptive Cruise Control back on.
Increasing Set Speed While Using Adaptive
Cruise Control
There are two ways to increase the set speed:
Use the accelerator to get to the higher speed.
Press the SET– button and then release the
button and the accelerator pedal. The vehicle will
now cruise at the higher speed.
Press the +RES button. Hold it there until the
desired set speed is displayed on the Driver
Information Center (DIC), then release the switch.
To increase your set speed in very small amounts,
move the switch briey to +RES. Each time this
is done, your set speed increases by 1 mph (1 km/h).
Your vehicle will not reach the set speed until the
system determines there is not a vehicle in front of you.
At that point, your vehicle speed will increase to the
set speed.

Alerting the Driver
The Adaptive Cruise
Control alert symbol is
located on the display at
the top of the instrument
panel to the right of
the driver.
The alert symbol will ash and a warning beep will
sound when driver action may be required. If Adaptive
Cruise Control is engaged, the alert symbol will
ash when:
Adaptive Cruise Control cannot apply sufficient
braking because you are approaching a vehicle
too rapidly.
The vehicle speed drops below about
20 mph (32 km/h).
A temporary condition prohibits Adaptive Cruise
Control from operating. SeeDIC Warnings and
Messages on page 3-75for more information.
A malfunction is detected in the system.
SeeDIC Warnings and Messages on page 3-75
for more information.
SeeDefensive Driving on page 4-2.
{CAUTION:
Adaptive Cruise Control has only limited
braking ability to slow your vehicle. In some
cases, Adaptive Cruise Control may not have
time to slow your vehicle enough to avoid a
collision. Be ready to take action and apply
the brakes yourself. SeeDefensive Driving
on page 4-2.
3-25

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 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.
3-27

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 message will appear on the DIC. SeeDIC Warnings
and Messages on page 3-75. 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.
{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.
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.
3-28

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
Press the Adaptive Cruise Control button or turn the
ignition off.
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 3-75for 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/retailer.

3-32

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.
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 LOCK/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 makes 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 transmission 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 3-42.

If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as warm
as they usually do and the climate control fan may cut
back to a lower speed. For more battery saving
information, see “Battery Saver Active Message” under
DIC Warnings and Messages on page 3-75.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up
or down. This is normal. If there is a problem, an
alert will be displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable
to the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-75.
