2005 Cadillac DeVille 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:

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 in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-35.
Trunk Lock Release
The trunk lock release
button is located to the left
of the steering wheel on
the instrument panel.
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 2-21.
2-12

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 2-35.
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.
SeeWinter Driving on page 4-25.
{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 2-32.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-37.

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.
SeeAutomatic Dimming Rearview Mirror with OnStar
®
on page 2-37.
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 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
a ve-second delay has occurred, the passenger’s side
mirror will return to its original position.
If further adjustment is needed after the mirror is tilted,
the mirror switch may be used.
This feature can be enabled/disabled through the
Driver Information Center (DIC). SeeDIC Vehicle
Personalization on page 3-68for 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 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 3-30
for more information.
