2006 CHEVROLET COBALT engine

Manual Transaxle
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the oor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a safety
feature.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition to START. When the engine starts, let go
of the key. The idle speed will go down as your
engine gets warm.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects the electrical system. If the
ignition key is turned to the START position,
and then released when the engine begins cranking,
the engine will continue cranking until the vehicle
starts or until it exceeds the maximum cranking time
allowed, approximately 15 seconds to prevent
cranking motor damage. To prevent gear damage,
this system also prevents cranking if the engine
is already running. The engine cranking can
be stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Holding your key in START for longer
than 15 seconds at a time will cause your
battery to be drained much sooner.And the excessive heat can damage your starter
motor. Wait about 15 seconds between each try to
help avoid draining your battery or damaging
your starter.
2. If it does not start, wait about 15 seconds and try
again to start the engine by turning the ignition to
START. Wait about 15 seconds between each try.
When the engine has run about 10 seconds to
warm up, your vehicle is ready to be driven. Do not
run your engine at high speed when it is cold.
If the weather is below freezing (32°F or 0°C), let
the engine run for a few minutes to warm up.
3. If the engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briey but then stops again, do the same thing, but
this time keep the pedal down for ve or six seconds.
This clears the extra gasoline from the engine.
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 do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will 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. Your vehicle may also have
an internal thermostat in the plug end of the cord. This
will prevent operation of the engine coolant heater
when the temperature is at or above 0°F (−18°C) as
noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. For
the 2.2L and 2.4L engines, the electrical cord is
located on the passenger’s side of the vehicle
between the strut and the air cleaner/lter.
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 do not, 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
a GM dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

Automatic Transaxle Operation
If your vehicle is equipped with an automatic transaxle,
the shift lever is located on the console between
the seats.
There are several different
positions for the automatic
transaxle.
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. If you are pulling a
trailer, seeTowing a Trailer (Automatic
Transaxle) on page 4-39orTowing a Trailer
(Manual Transaxle) on page 4-46.
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 apply your regular brakes before you can shift
from PARK (P) when the ignition key is in RUN.
2-23

If you cannot shift out of PARK (P), ease pressure
on the shift lever — push the shift lever all the way into
PARK (P) and also release the shift lever button as you
maintain brake application. Then move the shift lever into
the gear you wish. Press the shift lever button before
moving the shift lever. SeeShifting Out of Park (P)
(Automatic Transaxle) on page 2-30.
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, seeIf
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-30.
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)
while the engine is running at high speed may
damage the transaxle. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speeds when shifting your vehicle.
Notice:Shifting to a drive gear from NEUTRAL (N)
while the vehicle is moving could damage the
transaxle. Make sure the vehicle is stopped before
shifting from NEUTRAL (N) into a drive gear.
2-24

AUTOMATIC OVERDRIVE (D):This position is for
normal driving with the automatic transaxle. If you need
more power for passing, and you are:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push your
accelerator all the way down.
INTERMEDIATE (I):This position is also used for
normal driving. However, it offers braking from
the engine for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If repetitive shifts occur between third and fourth
gears on steep uphills, this position can be used to
prevent repetitive shifting. Fuel economy will be lower
than AUTOMATIC OVERDRIVE (D). Here are some
times you might choose INTERMEDIATE (I) instead of
AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.LOW (L):This position gives you even more power but
lower fuel economy than INTERMEDIATE (I). You
can use it on very steep hills, or in deep snow or mud.
If the shift lever is put in LOW (L), the transaxle will
not shift into LOW (L) 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, or parking brake to hold the vehicle
in place.
2-25

Manual Transaxle Operation
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.
NEUTRAL:Use this position when you start or idle
your engine.
REVERSE (R):To back up, press down the clutch
pedal 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.
For vehicles with the 2.0L Supercharged engine, press
down the clutch pedal. Then, lift up the ring on the shift
lever below the shift knob and shift into REVERSE (R).
Let up on the clutch pedal slowly while pressing the
accelerator pedal.

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. If you are
pulling a trailer, seeTowing a Trailer
(Automatic Transaxle) on page 4-39orTowing
a Trailer (Manual Transaxle) on page 4-46.
1. Hold the brake pedal down and set the parking
brake.
2. Move the shift lever into PARK (P) by holding the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
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 pushing
the button. If you can, it means that the shift lever
was not fully locked into PARK (P).
2-29

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you cannot 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 has 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.
Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-32.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-26.
