2003 Cadillac Seville Owner ManualM

Vehicle Damage Warnings
Also, in this book you will ®nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you 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.
You'll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a speci®c component, control,
message, gage or indicator.
If you need help ®guring out a speci®c name of a
component, gage or indicator, reference the following
topics:
·Seats and Restraint Systems in Section 1
·Features and Controls in Section 2
·Instrument Panel Overview in Section 3
·Climate Controls in Section 3
·Warning Lights, Gages and Indicators in Section 3
·Audio System(s) in Section 3
·Engine Compartment Overview in Section 5

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't 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 ªClimate Control
Systemº in the Index.
·If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Trunk Lock Release
The trunk lock release
button is located on the left
side of the instrument
panel below the lamp
controls.
Press the trunk lock release button upward 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 in the OFF position.
You can also press the button with the trunk symbol on
the remote keyless entry transmitter to open the
trunk. To disable this feature, see
Valet Lockout SwitchunderTheft-Deterrent Systems on page 2-19.
2-12

Running Your Engine While You
Are Parked
It's 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
ªEngine Exhaust.º
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 Ð with CO Ð can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
ªWinter Drivingº in the Index.
{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. Don't leave your vehicle when the engine
is running unless you have to. If you've left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle won't move, even when
you're 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 won't
move. See
Shifting Into Park (P) on page 2-32.
If you are parking on a hill and if you're pulling a trailer,
also see
Towing a Trailer on page 4-35.

Outside Automatic Dimming Mirror
If your 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.
See
Automatic Dimming Rearview Mirror with OnStarž
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 cause the passenger's 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
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). See
DIC Vehicle
Personalization on page 3-64for more information.
Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat. This mirror does not have a dimming
feature.
{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.
Outside Heated Mirrors
When you operate the rear window defogger, it also
warms both outside mirrors to help clear them of fog or
ice. See
Dual Climate Control System on page 3-28for more information.

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.
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 fan may cut back to a
lower speed. For more battery saving information, see
ªBattery Saver Active Messageº under
DIC Warnings
and Messages on page 3-56.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, cigarette lighters or the garage
door opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes (three minutes if a new car has 15 miles
(24 km) or less). Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened
or the courtesy lamp switch is turned on.
