2004 BUICK RANDEZVOUS Owner's Manual

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.
PARK (P):This gear position locks your front wheels.
It is the best position to use when you start your engine
because your vehicle cannot 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 must fully apply your
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. SeeShifting Out
of Park (P) on page 2-29for more information.
{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
Shifting Into Park (P) on page 2-27. If you are
pulling a trailer, seeTowing a Trailer on
page 4-42.
2-23

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 4-32.
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 (D):This position is for
normal driving. If you need more power for passing,
and you are:
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 will 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.
2-24

Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35°F (2°C) 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.
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 will
not 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.
2-25

Parking Brake
The parking brake is
located on the driver’s side
under the instrument panel.
To set the parking brake, hold the regular brake pedal
down with your right foot and push down on the parking
brake pedal with your left foot.
If the ignition is on, the brake system warning light will
come on. SeeBrake System Warning Light on page 3-44.To release the parking brake, hold the regular brake
pedal down with your right foot while you push down on
the parking brake pedal with your left foot. (To release
the tension on the parking brake cable, you will need to
apply about the same amount of pressure to the
parking brake pedal as you did when you set the parking
brake.) When you remove your foot from the parking
brake pedal, it will pop up to the released position.
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 4-42. That section shows
what to do rst to keep the trailer from moving.
2-26

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 4-42.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.2. To move the shift lever into PARK (P),
do the following:
2.1. Pull the lever toward you.
2-27

2.2. 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
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).
2-28

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 2-27.
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 which locks the shift lever in PARK (P)
when the ignition is in the OFF position. In addition, you
must fullyapplyyour regular brakesbeforeyou can
shift from PARK (P), when the ignition is in the
ON position. SeeAutomatic Transaxle Operation on
page 2-23.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way up into
PARK (P) as you maintain brake application. Then
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 the transaxle to NEUTRAL (N).
4. Start the vehicle and then shift to the gear
you want.
5. Have the system xed as soon as you can.
2-29

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
modied 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.
