BUICK REGAL 2002 Owners Manual

2-27
3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to
the floor and holding it there as you hold the key
in START for about three seconds. If the vehicle
starts briefly but then stops again, do the same
thing. This time keep the pedal down for five or
six seconds to clear the extra gasoline from the
engine. After waiting about 15 seconds, repeat the
normal starting procedure.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
Engine Coolant Heater (If Equipped)
In very cold weather, 0
F (-18
C) or colder, the
engine coolant heater can help. You'll get easier starting
and better fuel economy during engine warm
-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32
F (0
C), use of the
coolant heater is not required.

2-28 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is attached to the underside of the
vehicle's diagonal brace, which is located above
the engine air cleaner/filter assembly.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach,
use a heavy
-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you don't,
it could be damaged.
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 on the
console between the seats.

2-29
The above graphic is also displayed on your instrument
panel cluster.
Maximum engine speed is limited on automatic
transaxle vehicles when you're in PARK (P) or
NEUTRAL (N) to protect driveline components
from improper operation.
There are several different positions for your shift lever.
PARK (P): This position locks your front wheels.
It's the best position to use when you start your engine
because your vehicle can't 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 firmly set. Your vehicle can roll.
Don't 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 won't move, even when you're on fairly
level ground, always set your parking brake
and move the shift lever to PARK (P).
See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº
in the Index.

2-30
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transaxle shift lock control system. You must fully apply
your regular brakes before you can shift from PARK (P)
when the ignition is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever by pushing it
all the way into PARK (P) while keeping the brake pedal
pushed down. Release the shift lever button. Then move
the shift lever out of PARK (P). See ªShifting Out of
PARK (P)º in the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle
is moving forward could damage your transaxle.
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, see ªIf
You're Stuck: In Sand, Mud, Ice or Snowº in the Index.NEUTRAL (N): In this position, your engine
doesn't connect with the wheels. To restart when you're
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people
or objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.
NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn't covered by your warranty.

2-31
AUTOMATIC OVERDRIVE (
): This position is
for normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down.
You'll shift down to the next gear and have more power.
NOTICE:
If your vehicle seems to start up rather slowly,
or if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens,
have your vehicle serviced right away. Until then,
you can use SECOND (2) when you are driving
less than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (
) for higher speeds.
THIRD (3): This position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (
).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (
):

When driving on hilly, winding roads.

When towing a trailer, so there is less shifting
between gears.

When going down a steep hill.

When driving in no
-highway scenarios
(i.e. city streets, etc.)

2-32
SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
NOTICE:
Don't drive in SECOND (2) for more than
25 miles (40 km), or at speeds over 55 mph
(90 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE (
) or
THIRD (3) as much as possible.
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine.
FIRST (1): This position gives you even more power
(but lower fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transaxle won't shift
into first gear until the vehicle is going slowly enough.
NOTICE:
If your front wheels can't rotate, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a
solid object. You could damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK (P)
to hold your vehicle in position on a hill.

2-33
Parking Brake
To set the parking brake,
hold the regular brake pedal
down with your right foot.
Push down the parking
brake pedal with your
left foot.
To release the parking brake, hold the regular brake
pedal down with your right foot 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.
A warning chime will sound if the parking brake is set,
the ignition is on and the shift lever is not in PARK (P)
or NEUTRAL (N).NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them, and you could also damage other
parts of your vehicle.
If you are towing a trailer and parking on any hill, see
ªTowing a Trailerº in the Index. That section shows
what to do first to keep the trailer from moving.

2-34
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 firmly 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 won't move,
even when you're on fairly level ground, use
the steps that follow. If you're pulling a trailer,
see ªTowing a Trailerº in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.
2. Move the shift lever into
PARK (P) by holding in
the button on the lever
and then pushing the
lever all the way toward
the front of your vehicle.
Then turn the ignition
key to LOCK.
3. 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).

2-35 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 firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move the
shift lever out of PARK (P) without first pushing the
button. If you can, it means that the shift lever wasn't
fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you don't 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 find it difficult to pull the shift
lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave
the driver's seat. To find out how, see ªShifting Into
PARK (P)º in the Index.
When you are ready to drive, move the shift lever out
of PARK (P) before you 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).

2-36
Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shiftlock
control system. You must fully apply your regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. See ªAutomatic Transaxle
Operationº in the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing it all the way into PARK (P)
while keeping the brake pedal pushed down. Then move
the shift lever out of PARK (P).
If you ever hold the brake pedal down but still can't
shift out of PARK (P), try this:
1. Turn the ignition key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and shift to the drive gear you want.
5. Have the vehicle fixed as soon as you can.
Shift Lock Release
Your vehicle is equipped with an electric park lock
system. The system is designed to prevent ignition key
removal unless the shift lever is in PARK (P) (with the
shift lever button fully released).
The system also prevents the shift lever from moving out
of PARK (P) when the ignition is in OFF or in LOCK.
The park lock system is always functional except in the
case of a dead or low voltage (less than 9 V) battery.
If your vehicle has a dead battery or a battery with low
voltage, there are two override access slots that will
allow you to override the park lock system.
The first access slot is located underneath the steering
column below the lock cylinder. To use this slot, do
the following:
1. Verify that the shift lever is in PARK (P) (with the
shift lever button released.)
2. Remove the override access slot cap, which will then
show the override mechanism release button.
3. Insert a key or tool into the access slot and then press
in and hold the override mechanism release button.
4. Turn the ignition key to OFF.
5. Remove the key from the ignition switch.
6. Put the override access slot cap back on.
