2003 CHEVROLET VENTURE engine

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
electrical cord is located on the driver's side of the
engine compartment.
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 will
not 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
Maximum engine speed is limited 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.
2-34

PARK (P):This gear position locks your front wheels.
It's the best position to use when you start your
engine because your vehicle can't move easily.
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
applyyour regular brakesbeforeyou can shift from PARK (P)
when the ignition key is in RUN. As you step on the
brake pedal, while in PARK (P), you may hear a
click from the solenoid of the system. This ensures that
the system is operating properly.
If you cannot shift out of PARK (P), ease pressure on
the shift lever ± push the shift lever all the way into
PARK (P) as you maintain brake application. Then move
the shift lever into the gear you wish. See
Shifting Out
of Park (P) on page 2-41.
{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.
2-35

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, see If
You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-30.
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
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 our 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 (D):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 all the way down.
You'll shift down to the next gear and have more power.
Notice:Driving your vehicle if you notice that it
is moving slowly or not shifting gears as you
increase speed may damage the transaxle. Have
your vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than
35 mph (55 km/h) and AUTOMATIC OVERDRIVE (D)
for higher speeds until then.
2-36

Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35ÉF (2ÉC) or colder. You may notice
that the transaxle will shift at a higher vehicle speed until
the engine is warmed up. This is a normal condition
designed to provide heat to the passenger compartment
and defrost the windows more quickly. See
Climate
Control System on page 3-25for more information.
THIRD (3):This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
·When driving on hilly, winding roads.
·When towing a trailer (so there is less shifting
between gears).
·When going down a steep hill.
SECOND (2):This position gives you more power 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:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
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 THIRD (3) for higher
speeds.
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
downshift into ®rst gear until the vehicle is going slow
enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
2-37

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 with your left foot.2. Move the shift lever into PARK (P) like this:
·Pull the lever toward you.
2-39

·Move 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).
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 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 wasn't fully locked into PARK (P).
2-40

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 2-39.
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).
Shifting Out of Park (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fullyapplyyour regular
brakesbeforeyou can shift from PARK (P), when
the ignition is in RUN.
As you step on the brake pedal, while in PARK (P), you
may hear a click from the solenoid of the system.
This ensures that the system is operating properly. See
Automatic Transaxle Operation on page 2-34.
If you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing the shift lever all the way into
PARK (P) as you maintain brake application. Then
try to move the shift lever into the gear you want. 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 then shift to the drive gear
you want.
5. Have the vehicle ®xed as soon as you can.
2-41

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.
Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can not see
or smell. It can cause unconsciousness and
death.
You might have exhaust coming in if:
·Your exhaust system sounds strange or
different.
·Your vehicle gets rusty underneath.
·Your vehicle was damaged in a collision.
·Your vehicle was damaged when driving
over high points on the road or over road
debris.
·Repairs were not done correctly.
·Your vehicle or exhaust system had been
modi®ed improperly.
If you ever suspect exhaust is coming into
your vehicle:
·Drive it only with all the windows down to
blow out any CO; and
·Have your vehicle ®xed immediately.
