2008 CADILLAC DTS engine

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-34.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Also see “If You Are Caught in a Blizzard” under
Winter Driving on page 4-16.
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
after you move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park on page 2-31.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-27.

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.

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.
Footwell Lamps
If your vehicle has footwell lamps, they are located
under the instrument panel and at the rear of the front
seats. These lamps provide soft light to the front
and rear oor areas. They dim with the instrument panel
cluster lights, before going out completely.
Footwell lighting brightness can be adjusted with the
instrument panel brightness control located below
the exterior lamps control. SeeInstrument Panel
Brightness on page 3-37. The footwell lights will turn off
before the instrument panel lights are at their lowest
level of brightness.
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.
3-38

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.

?(Recirculation):Press this button to recirculate
cabin air through the vehicle. An indicator light below the
button comes on to show that this mode is activated.
This mode can be used to prevent outside air and odors
from entering the vehicle or to help cool the air inside
the vehicle more quickly. This mode cannot be selected
while in the defog or defrost modes. If you try to
select the recirculation mode, the indicator light ashes
three times and turns off.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode.
wx(Driver’s Temperature Controls):Press these
buttons next to the fan control to manually increase
or decrease the temperature inside the vehicle.
wx(Passenger’s Temperature Controls):Press
these buttons next to the mode control to manually
increase or decrease the temperature for the front
passenger. If the passenger’s climate control system is
off, pressing one of these buttons turns it on.PASS (Passenger’s Climate Control):Press this
button to turn the passenger’s climate control systems
on or off. When the passenger’s climate control
system is on, the passenger’s temperature setting is
displayed. The temperature selected by the front
passenger also controls the rear system air temperature
unless the rear seat passengers select their own
comfort setting.
If the PASS button is pressed to turn the passenger
temperature setting off, the driver’s temperature
knob will control the temperature for the entire vehicle.
AUX:If your vehicle has a rear climate control
system, press this button to turn the rear climate control
fan on for automatic operation. After the AUX button
is pressed, the indicator light comes on. Press the button
again to turn the auxiliary fan off. SeeRear Climate
Control System on page 3-49.#(Air Conditioning):Press the center of the left
control knob to override the automatic system and turn
the air conditioning system on or off. When in AUTO,
the air conditioning compressor comes on automatically,
as necessary.
The air conditioning system removes moisture from the
air, so a small amount of water may drip underneath
the vehicle while idling or after turning off the engine.
This is normal.
