2003 CHEVROLET MONTE CARLO Engine

Engine Coolant Heater
Your vehicle may be equipped with this feature. In very
cold weather, 0ÉF (-18ÉC) 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 32ÉF (0ÉC), use of the coolant heater is not
required.
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 diagonal
brace, which is located above the engine air
cleaner/®lter 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 ®re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-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 located on
the console between the front seats.
The above graphic is displayed on your instrument
panel cluster.
Maximum engine speed is limited on automatic transaxle
vehicles while you're in PARK (P) or NEUTRAL (N) to
protect driveline components from improper operation.
2-21

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 ®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). See ªShifting Into Park (P)º in the
Index. If you are pulling a trailer, see ªTowing
a Trailerº in the Index.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)
while the ignition is in ON. 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 and the shift lever button pressed
in. Release the shift lever button. Then move the
shift lever out of PARK (P). SeeShifting Out of Park (P)
on page 2-27.
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 If
You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-28.
2-22

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 into a drive gear while your engine is
ªracingº (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 racing.
Notice:Damage to your transaxle caused by
shifting into a drive gear with the engine running at
high speed isn't covered by your warranty.
AUTOMATIC OVERDRIVE (
X): 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 (D) 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 (
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.
·When driving in non-highway scenarios
(i.e. city streets, etc.).
2-23

SECOND (2):This position gives you more power than
THIRD (3) but lower fuel economy than THIRD (3).
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
THIRD (3) or AUTOMATIC OVERDRIVE (D) 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 in FIRST (1), the transaxle won't shift into
®rst gear until the vehicle is going slowly enough.
Notice:If your front wheels won't turn, 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 to hold your vehicle in position on a hill.
Parking Brake
The parking brake is
located to the left of the
brake pedal, near the
driver's door.
To set the parking brake, hold the brake pedal down
with your right foot. Push down the parking brake pedal
with your left foot.
To release the parking brake, hold the 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).
2-24

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
Towing a Trailer on page 4-34. That section shows 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, see ªTowing a Trailerº in the
Index.1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) like this:
·Press and hold in the shift lever button located
on the left side of the shift lever.
·Push the shift lever all the way toward the front
of the vehicle.
3. Turn the ignition key to OFF.
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).
2-25

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've moved the shift lever into the PARK (P) position,
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 (or, if you have the console
shift lever, without ®rst 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 ®nd 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 ®nd out how, see
Shifting Into Park (P)
on page 2-25.
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).
2-26

Shifting Out of Park (P)
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 ON. See
Automatic Transaxle Operation on
page 2-21.
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), being sure to press
the shift lever button.
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 ACC.
2. Apply and hold the brake pedal 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 ®xed as soon as you can.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass or other
things that can burn.
