2009 CADILLAC DTS Owners Manual

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 a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information,
seeEngine Exhaust on page 2-36.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake rmly set.
The vehicle can roll. Do not leave the 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 the vehicle will not move, even when
you are on fairly level ground, always set the
parking brake after you move the shift lever
to P (Park).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-33.
If parking on a hill and pulling a trailer, seeTowing a
Trailer on page 4-28.

Mirrors
Automatic Dimming Rearview Mirror
The vehicle has an automatic dimming inside rearview
mirror with a compass display. The mirror may also
have OnStar
®controls and Intellibeam™. For more
information on Intellibeam™, see “Intellibeam Intelligent
High-Beam Headlamp Control System” underExterior
Lamps on page 3-29. For more information about
OnStar
®, seeOnStar®System on page 2-51.
Automatic Dimming Mirror Operation
Automatic dimming reduces the glare of lights from
behind the vehicle. The dimming feature comes on and
the indicator light illuminates each time the vehicle is
started.
O(On/Off):Press and holdOfor about three seconds
to turn the dimming feature and compass display on
or off.
AUTO
3(Vehicles with Intellibeam™):Press and
hold for approximately three seconds to turn the
compass display on or off.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror.
Use a soft towel dampened with water.
Compass
Compass Operation
PressOor AUTO3, depending on the vehicle,
to turn the compass on or off.
When the ignition and the compass feature are on, after
a few seconds, the mirror will display the compass
heading. The compass automatically calibrates as the
vehicle is driven.
Compass Calibration
If after a few seconds, the display does not show the
correct direction, (for example, N for North), there
may be a strong magnetic eld interfering with the
compass. Interference can be caused by a magnetic
antenna mount, magnetic note pad holder or a
similar magnetic item.
2-38

The compass can be placed in calibration mode
manually by pressing and holding
Oor AUTO3,
depending on the vehicle, until a C is shown in
the compass display.
The compass can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads a direction.
Compass Variance
The compass is set to zone eight. If you do not
live in zone eight or drive out of the area, the
compass variance needs to be changed to the
appropriate zone.
To adjust for compass variance:
1. Find the current location and variance
zone number on the following zone map.
2. Press and hold
Oor AUTO3until a zone
number displays.
3. Once the zone number displays, press
Oor
AUTO
3repeatedly until the correct zone number
displays. Stop pressing the button and the mirror
will return to normal operation. If C appears in
the compass window, the compass may need
calibration. See “Compass Calibration” listed
previously.

Outside Power Foldaway Mirrors
Controls for the outside
power mirrors are located
on the driver door armrest.
Mirror Adjustment
1. Press (C) to fold the mirrors out to the driving
position.
2. Press (D) to fold the mirrors in to the folded
position.
Resetting the Power Foldaway Mirrors
Reset the power foldaway mirrors if:
The mirrors are accidentally obstructed while
folding.
They are accidentally manually folded/unfolded.
The mirrors do not stay in the unfolded position.
The mirrors vibrate at normal driving speeds.
Fold and unfold the mirrors one time using the mirror
controls to reset them to their normal position. A noise
may be heard during the resetting of the power
foldaway mirrors. This sound is normal after a manual
folding operation.
Outside Automatic Dimming Mirror
If the vehicle has this feature, the driver side mirror
adjusts for the glare of headlamps behind you.
This feature is controlled by the on and off settings on
the automatic dimming rearview mirror.
2-40

Park Tilt Mirrors
If your vehicle is equipped with memory mirrors,
it is capable of performing the park tilt mirror feature.
This feature allows the driver and passenger side
mirror to tilt to a factory programmed position when
the vehicle is in R (Reverse). This feature may be
useful in allowing you to view the curb when you are
parallel parking.
When the vehicle is shifted out of R (Reverse) and
either a ve-second delay has occurred, or the
ignition is turned to LOCK/OFF, the driver and
passenger side mirror will return to its original
position.
This feature can be enabled/disabled through
the Driver Information Center (DIC). SeeDIC
Vehicle Customization on page 3-86for more
information.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you could
hit a vehicle on the right. Check the inside mirror or
glance over your shoulder before changing lanes.
The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat.
Outside Heated Mirrors
=(Rear Window Defogger):Press to heat the mirrors.
See “Rear Window Defogger” underDual Climate Control
System on page 3-40for more information.
Side Blind Zone Alert (SBZA)

Object Detection Systems
Ultrasonic Front and Rear Parking
Assist (UFRPA)
For vehicles with the Ultrasonic Front and Rear Parking
Assist (UFRPA) system, it operates at speeds less
than 5mph (8 km/h), and assists the driver with parking
and avoiding objects. It can determine how close
objects are to the front bumper, up to 4 feet (1.2 m)
in front of the vehicle and the rear bumper, up to
8 feet (2.5 m) behind the vehicle. The distance sensors
are located on the front and rear bumper.
{CAUTION:
The Ultrasonic Front and Rear Park Assist
(UFRPA) system does not replace driver vision.
It cannot detect:
objects that are below the bumper,
underneath the vehicle, or if they are too
close or far from the vehicle
children, pedestrians, bicyclists, or pets.
If you do not use proper care before moving
forward and while backing; vehicle damage, injury,
or death could occur. Even with UFRPA, always
check in front of your vehicle before moving
forward and behind your vehicle before backing
up. While moving forward and backing, be sure to
look for objects and check your vehicle’s mirrors.
2-42

The front display is located on top of the instrument panel
to the right of the driver. The front display will have either
three or six lights to provide distance and system
information. With Adaptive Cruise control (ACC), it will
have three lights along with the ACC lights. Without ACC,
it will have six lights. High-toned beeps from the front
speakers are for objects detected near the front bumper.
The rear display is located near the rear window and can
be seen by looking over your right shoulder. The rear
display uses three color-coded lights to provide distance
and system information. Low-toned beeps from the rear
speakers are for the rear bumper.
How the System Works
UFRPA comes on automatically when the shift lever
is moved out of P (Park). The system does not
work at a forward or reverse speed greater than
5 mph (8 km/h).
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below hood or trunk level.
Objects must also be within 4 feet (1.2 m) in front of
the vehicle and 8 feet (2.5 m) from the rear bumper.
This distance may be less during warmer or humid
weather.
When backing up, if objects are detected at the same
time near both the front and rear bumpers, both
color-coded light displays will notify you of objects close
to each bumper. If there are objects detected near both
bumpers, the beeps will only be sounded to notify that
objects are close to the rear bumper. However, if while
the vehicle is backing up and an object comes within
1 ft (0.3 m) of the front bumper, and at the same time
there is another object further than 1 ft (0.3 m) from the
rear bumper, then the beeps will only be sounded to
notify you of the closer object that is near the front
bumper.
The system can be disabled using the Driver Information
Center (DIC). See “Parking Assist” underDIC Operation
and Displays on page 3-68for more information. Front Parking Assist
