CHEVROLET AVEO 2002 Service Repair Manual

Automatic Transaxle Operation
If your vehicle has an automatic transaxle, the shift
lever is located on the console between the seats.
Movement between certain positions requires pushing
the shift lever toward the passenger side while shifting.
This prevents you from changing positions unexpectedly
by blocking the straight movement of the shift lever
while the vehicle is moving.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) (Automatic Transaxle)
on page 2-29.
2-22

Ensure that 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 apply
your regular brakes before you can shift from PARK (P)
when the key is in ON. If you cannot shift out of
PARK (P) while holding the brake pedal down, see
Shifting Out of Park (P) (Automatic Transaxle) on
page 2-30.
REVERSE (R):Use this gear to back up.
When shifting from NEUTRAL (N) to REVERSE (R),
you need to apply the regular brake and push the shift
lever toward the passenger side of the vehicle and
then forward.
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 4-28.NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart while 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.
2-23

AUTOMATIC OVERDRIVE (D4):This position is for
normal driving.
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 (D4) for higher speeds
until then.
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:Do not drive in SECOND (2) at speeds
over 65 mph (105 km/h), or you can damage
the transaxle. Use AUTOMATIC OVERDRIVE (D4) as
much as possible. Do not 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 will not shift
into first gear until the vehicle is going slowly 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.
If there is a malfunction with the automatic transaxle,
the malfunction indicator lamp (MIL) or the HOLD
indicator light will turn on or flash. SeeMalfunction
Indicator Lamp on page 3-28orHold Mode Light
on page 3-28.
Have your vehicle fixed as soon as possible.
2-24

Hold Mode
If your vehicle’s transaxle has hold mode, you can
select this mode to drive with some characteristics of
a manual transaxle. With hold mode turned on, the
automatic transaxle will stay in a specific gear range.
Press the HOLD button on the shift lever console to turn
on hold mode. Press the button again to turn off hold
mode, and return to normal automatic transaxle
operation.While on, the HOLD indicator light on the secondary
information center will light up. SeeHold Mode Light on
page 3-28.
When hold mode is activated, the transaxle is fixed in
the gear selected.
Hold Mode Features
Winter Function
Select hold mode while in AUTOMATIC
OVERDRIVE (D4) to help the vehicle maintain
traction on slippery road surfaces, such as snow,
mud, or ice.
Manually Controlling Shift
Select hold mode to use your automatic transaxle like
a three-speed manual transaxle.

Manual Transaxle Operation
Five-Speed
This is your shift pattern.
Here is how to operate your manual transaxle:
FIRST (1):Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal as
you press the accelerator pedal.You can shift into FIRST (1) when you are going less
than 20 mph (32 km/h). If you have come to a complete
stop and it is hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch. Press
the clutch pedal back down. Then shift into FIRST (1).
SECOND (2):Press the clutch pedal as you let up
on the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
THIRD (3), FOURTH (4) and FIFTH (5):Shift into
THIRD (3), FOURTH (4) and FIFTH (5), the same way
you do for SECOND (2). Slowly let up on the clutch
pedal as you press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press
the clutch pedal and the brake pedal, and shift to
NEUTRAL.
2-26

NEUTRAL:Use this position when you start or idle
your engine.
REVERSE (R):To back up, press down the clutch
pedal, lift up the ring on the shift lever and shift
into REVERSE (R). Let up on the clutch pedal slowly
while pressing the accelerator pedal.
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.
Also, use REVERSE (R), along with the parking brake,
for parking your vehicle.Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you could
lose control of your vehicle. You could injure

Shifting Into Park (P)
(Automatic Transaxle)
{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.
1. Hold the brake pedal down and set the parking
brake.
2. Move the shift lever into the PARK (P) position by
pushing the lever toward the passenger side of the
vehicle and then up.
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 firmly 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). If you can, it means
that the shift lever was not fully locked into PARK (P).
2-29

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 find 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 find out how, seeShifting Into Park (P)
(Automatic Transaxle) on page 2-29.
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)
(Automatic Transaxle)
Your automatic transaxle vehicle has an automatic
transaxle shift lock control system. You have to fully apply
your regular brakes before you can shift from PARK (P)
when the ignition is turned to ON. SeeAutomatic
Transaxle Operation on page 2-22.
If you cannot shift out of PARK (P) while holding the
brake pedal down, try this:
1. Set the parking brake.
2. Turn the ignition off and remove the key.
3. Remove the cover over the shift-lock release slot
by prying it off using a small, flat object, like a
screwdriver. The shift-lock release slot is located at
the top of the shift lever.

4. Insert the key into the
shift-lock release slot
and press and hold
the key.
5. Shift to NEUTRAL (N).
6. Remove the key from the shift-lock release slot,
insert the key into the ignition and start the
engine.
7. Replace the shift-lock release slot cover.
8. Apply and hold the regular brake fully and release
the parking brake.
9. Shift to the gear you want.
10. Have the system fixed as soon as you can.Parking Your Vehicle
