2005 BUICK LESABRE tow

To program the new key, do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the current driver’s key in the ignition
and start the engine. If the engine will not start, see
your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY light comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, see your
dealer to have a new key made.
Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km). Do not
make full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-38for more information.

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.

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on
the steering column.
PARK (P):This position locks your front wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
{CAUTION:
It is 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). SeeShifting Into Park (P) on
page 2-28. If you are pulling a trailer, see
Towing a Trailer on page 4-38.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle shift
lock control system. You have to fully apply your regular
brakes before you can shift from PARK (P) while the
ignition is in RUN. If you cannot shift out of PARK (P),
ease pressure on the shift lever and push the shift lever
all the way into PARK (P) as you maintain brake
application. Then move the shift lever into the gear you
want. SeeShifting Out of Park (P) on page 2-30.
2-25

REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, seeIf
You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-30.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine racing may damage the transaxle.
The repairs would not be covered by your warranty.
Be sure the engine is not racing when shifting
your vehicle.
AUTOMATIC OVERDRIVE (
X):This position is for
normal driving. If you need more power for passing, and
you are:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have
more power.
THIRD (3):This position is also used for normal driving.
However, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (
X).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (
X):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
2-26

To release the parking brake, hold the regular brake
pedal down and push the parking brake pedal with your
left foot. When you lift your left foot, the parking brake
pedal will follow it to the released position.
If you try to drive with the parking brake on, after about
20 feet (6.1 m) a chime will sound continuously until
you release the parking brake. Also, the brake light will
stay on until the parking brake is released.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-38. That section
explains what to do rst to keep the trailer from moving.Shifting Into Park (P)
{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. 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, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-38.
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) by pulling the
shift lever toward you and moving the lever up as
far as it will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
2-28

Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pulling it
toward you. If you can, it means that the shift lever
was not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may nd it difficult to pull the shift
lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into Park (P)
on page 2-28.
When you are ready to drive, move the shift lever out of
PARK (P)beforeyou release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transaxle, so you
can pull the shift lever out of PARK (P).
