2003 Buick LeSabre 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
To unlock the trunk from the outside, insert the master
key and turn it clockwise.
Remote Trunk Release Lockout
The TRUNK release button
is located on the driver's
door trim map pocket.
Push this button to open the trunk. The transaxle must
be in PARK (P) or NEUTRAL (N) for the remote
trunk release button to work.
To lock the trunk from inside your vehicle, insert the
master key and turn it clockwise to LOCK. The VALET
key will not work in this procedure.

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. 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 and 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 2-28.
If you are parking on a hill and if you're pulling a trailer,
also see
Towing a Trailer on page 4-35.
2-32

The mirrors may also have an arrow that ¯ashes when
the turn signal is used. SeeTurn Signal/Multifunction
Lever on page 3-7.
Outside Curb View Assist Mirror
If you have the Memory Seat and Mirrors feature, the
passenger's outside rearview mirror includes a tilt-down
feature that operates when the shift lever is in
REVERSE (R). This feature assists the driver, improving
rear obstacle detection. When the vehicle is shifted
out of REVERSE (R), the passenger mirror will return to
its original position after a ®ve-second delay. This
delay prevents movement of the mirror if multiple gear
transitions (REVERSE (R) to AUTOMATIC
OVERDRIVE (
X) to REVERSE (R)) occur during a
parallel parking maneuver. This feature can be
programmed on or off through the personal choice
selection menu. See
DIC Vehicle Personalization on
page 3-50for programming instructions.
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.
{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 Automatic Dimming
Heated Mirror
If you have this feature, the outside driver's mirror will
adjust for the glare of headlamps behind you. This
feature is controlled using the on and off settings on the
automatic dimming rearview mirror. See
Automatic
Dimming Rearview Mirror on page 2-33.
When you operate the rear window defogger, the
heated driver's and passenger's outside rearview mirrors
are warmed to help clear them of ice and snow. See
ªRear Window Defoggerº under
Climate Control System
on page 3-24orDual Automatic Climate Control
System on page 3-26for more information.

Express Open:When the glass panel is express
opening, pressing the switch in any direction will stop it
in a partially-opened position. The glass panel may
be fully opened by pressing the switch rearward again.
If you press and hold the switch in the express open
position for more than one and a half seconds, the
express open operation will be overridden and
the sunroof will operate manually.
Close:To close the glass panel, press and hold the
switch forward. As the glass panel reaches the closed
position, it will open slightly toward the vent position and
then drop down to the closed position to provide a
better seal. The sunshade must be closed manually.
Vent:Once the sunroof is closed, it can be opened to
the vent position by pushing the switch upward. To
close the glass panel, pull the switch downward. The
sunshade must be opened and closed manually for vent
operation.Vehicle Personalization
Memory Seat and Mirrors
If your vehicle has this feature, the controls are located
on the driver's door panel, and are used to program
and recall memory settings for the driver's seating,
outside mirror positions and climate controls. See
Climate Control System on page 3-24for more
information.
To save your seat and mirror positions into memory,
use the following procedure:
1. First identify the DRIVER # on the Driver Information
Center (DIC) by pressing the MEMORY button 1
or 2 or by pressing the unlock button on the remote
keyless entry transmitter. See
Driver Information
Center (DIC) on page 3-45.
