2005 Buick LeSabre 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:

Heated Seats
If your vehicle has this feature, press this button to turn
on the heating element in the seat.
The heated seat buttons
are located on the driver’s
and front passenger’s
door panel.
When the heated seat button is rst pressed, the high
setting is activated. The word “HI” lights up above
the button. Press the button again for the low setting.
The word “LO” lights up above the button. The third
press of the button turns the feature off.The low setting warms the seatback and cushion until
the seat nears body temperature. The high setting heats
the seat to a slightly higher temperature.
The heated seats can be used only while the ignition is
turned on. When the ignition is turned off, the heating
element is also turned off.
Reclining Seatbacks
If your vehicle has the manual recliner, lift the lever on
the outboard side of the seat and move the seatback
to the desired position. Release the lever to lock
the seatback. Pull up on the lever without pushing
on the seatback and the seatback will go to an
upright position.

Ignition Positions
With the key in the ignition switch, you can turn to ve
different positions.
A (ACCESSORY):In this position you can operate your
electrical accessories. Press in the ignition key as you
turn the top of it toward you.B (LOCK):This is the only position from which you can
remove the key. This position locks your ignition and
transaxle. It is a theft-deterrent feature.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
C (OFF):This position lets you turn off the engine. It
does not send any power to the accessories. The
instrument panel cluster will remain powered in OFF to
illuminate the gear shift indicator. The cluster will
also activate the parking brake light when the parking
brake is set. Use OFF if you must have your vehicle in
motion while the engine is not running.
D (RUN):This is the position the switch returns to after
you start your engine and release the ignition key.
This is the position for driving. Even when the engine is
not running, you can use RUN to operate your
electrical accessories and to display some instrument
panel warning lights.
E (START):This position starts your engine. When the
engine starts, release the ignition key. The switch
will return to RUN for normal driving.
2-22

Key Reminder Warning
If you leave your key in OFF, you will hear a warning
chime when you open the driver’s door.
Always leave your key in LOCK while the engine is off.
If you leave it in any other position, you will drain
your battery power.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key, you
will still have power to such accessories as the
power windows, audio steering wheel controls (if
equipped), clock, sunroof (if equipped) and the radio for
up to 10 minutes. The instrument panel cluster lights
will stay on for a few seconds, then will go out. Once you
open a door, the power will shut off.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
The engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If the engine does not start within 10 seconds, hold
your key in START for about 10 seconds at a time
until the engine starts. Wait about 15 seconds
between each try.
When your engine has run for about 10 seconds to
warm up, your vehicle is ready to be driven. Do
not race your engine when it is cold.
If the weather is below freezing (32°F or 0°C), let
the engine run for a few minutes to warm up.
2-23

{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 will not
move. SeeShifting Into Park (P) on page 2-28.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-38.
Mirrors
Manual Rearview Mirror
While sitting in a comfortable driving position, adjust the
mirror so you can see clearly behind your vehicle.
Grip the mirror in the center to move it up or down and
side to side. The control at the bottom of the mirror
is the day/night feature that allows adjustment to
the mirror so that the glare of headlamps from behind is
reduced. Push the tab for daytime use; pull it for
night use.
Automatic Dimming Rearview Mirror
The vehicle may have an automatic dimming rearview
mirror. It may also have OnStar®controls. SeeOnStar®
System on page 2-37for more information.
At night, when glare from lights is high, the mirror will
gradually darken. This change may take a few seconds.
The mirror will return to its clear daytime state when
glare is reduced.
