2006 Cadillac DTS Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

3. Slide the new battery into the transmitter with the
positive side of the battery facing down. Use a
type CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tight, so
water will not get in.
5. Test the operation of the transmitter with
the vehicle.
Remote Vehicle Start
The remote vehicle starting feature allows you to start
the engine from outside of the vehicle. It also starts
up the vehicle’s automatic climate control system.
If moderate or warmer outside temperatures exist, the
climate control system will default to automatic
temperature control and fan speed to regulate and
maintain a moderate inside temperature. When
the outside temperature is cold, the climate control
system will start up the rear window defogger and
default to the front windshield defrost mode with the
heat on and the fan blower set to high. If the vehicle has
heated seats, they will also turn on.SeeHeated and Cooled Seats on page 1-3for additional
information. Cooled seats are not activated during a
remote start. Normal operation of the climate control
system will return after the key is turned to RUN.
SeeDual Climate Control System on page 3-44.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
Your remote keyless entry transmitter, with the remote
start button, provides an increased range of operation.
However, the range may be less while the vehicle
is running. As a result, you may need to be closer to
your vehicle to turn it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, see “Remote Keyless
Entry System Operation” listed previously for additional
information.

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-33.
Remote Trunk Release
G
(Remote Trunk Release):The remote trunk
release button is located to the left of the steering wheel
next to the instrument panel brightness control. Press
the button to open the trunk. To use this feature,
your vehicle must be in PARK (P) or NEUTRAL (N) and
the valet lockout switch must be off.
You can also press the button with the trunk symbol on
the remote keyless entry transmitter to open the
trunk. To disable this feature, seeValet Lockout Switch
on page 2-19.
2-13

Running the Engine 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 2-33.
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.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-26.
{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 your
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 (P) on page 2-30.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-38.

Outside Automatic Dimming Mirror
If the vehicle is equipped with this feature, the
driver’s side mirror will adjust for the glare of headlamps
behind you. This feature is controlled by the on and
off settings on the automatic dimming rearview mirror.
Outside Curb View Assist Mirror
If your vehicle is equipped with memory mirrors, it will
also be capable of performing the curb view assist mirror
feature. This feature will allow the driver’s and
passenger’s side mirror to tilt to a factory programmed
position when the vehicle is in REVERSE (R). This
feature may be useful in allowing you to view the curb
when you are parallel parking.
When the vehicle is shifted out of REVERSE (R) and
either a thirty-second delay has occurred, the vehicle
speed is greater than 8 mph (12 kph), or the ignition is
turned to off, the driver’s and passenger’s side mirror
will return to its original position.
This feature can be enabled/disabled through the Driver
Information Center (DIC).
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 your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be seen from
the driver’s seat. This mirror does not have a
dimming feature.
Outside Heated Mirrors
When you operate the rear window defogger, it also
warms both outside mirrors to help clear them of fog or
ice. SeeDual Climate Control System on page 3-44
for more information.
