engine PONTIAC TORRENT 2008 User Guide

To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to the ACC/ACCESSORY or LOCK/OFF
position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms up
and lubricates all moving parts.Notice:The 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/retailer. 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
The engine coolant heater, if available, can help in cold
weather conditions at or below 0°F (−18°C) for easier
starting and better fuel economy during engine warm-up.
Plug in the coolant heater at least four hours before
starting your vehicle. An internal thermostat in the
plug-end of the cord may exist which will prevent engine
coolant heater operation at temperatures.
2-23

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the passenger’s side of the
engine compartment, near the radiator.
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
your dealer/retailer in the area where you will be
parking your vehicle. The dealer/retailer can give you
the best advice for that particular area.

Automatic Transmission Operation
(3.4L V6 with 5-Speed)
The shift lever is located on the center console. When
you change gears, the different shift positions will display
on the instrument panel cluster.
There are several different positions for the automatic
transmission.
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) on
page 2-33. If you are pulling a trailer, see
Towing a Trailer on page 4-32.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system.
2-25

You must fully apply your regular brakes rst and then
press the shift lever button before you can shift from
PARK (P) when the ignition key is in ON/RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
lever and push the shift lever all the way into PARK (P) as
you maintain brake application. Then press the shift lever
button and move the shift lever into another gear. See
Shifting Out of PARK (P) on page 2-35.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
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 transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-21.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while the 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 running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
Notice:Shifting to a drive gear from NEUTRAL (N)
while the vehicle is moving could damage the
transmission. Make sure the vehicle is stopped
before shifting from NEUTRAL (N) into a drive gear.
2-26

DRIVE (D):This position is for normal driving with the
automatic transmission. It provides the best fuel
economy for your vehicle. 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.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-12.
INTERMEDIATE (I):This position is also used for
normal driving. However, it reduces vehicle speed without
using your brakes for slight downgrades where the
vehicle would otherwise accelerate due to steepness of
grade. If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to prevent
repetitive types of shifts. You might choose
INTERMEDIATE (I) instead of DRIVE (D) when driving
on hilly, winding roads and when towing a trailer, so that
there is less shifting between gears.
LOW (L):This position reduces vehicle speed more
than INTERMEDIATE (I) without actually using
your brakes. You can use it on very steep hills, or in
deep snow or mud. If the shift lever is put in LOW (L),
the transmission 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 transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.Transmission Overheating
If the transmission uid temperature rises above
284°F (140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-35for
more information. When the transmission overheats
it will go into a protection mode and will default shift into
fth gear if in the DRIVE (D) position, or second gear
if in the LOW (L) position. Continue driving the vehicle in
either position depending on the required vehicle
speed and load. Once the uid temperature lowers to
the normal temperature range, the transmission will
return to the normal shift patterns. Towing or driving on
long hills can cause the transmission uid temperature
to be higher than normal. If the transmission uid
temperature will not cool, you may need to pull over and
check the transmission uid level. You should also
check the engine coolant temperature. If it is hot, see
Engine Overheating on page 5-25.
2-27

Automatic Transmission Operation
(3.6L V6 with 6-Speed)
The shift lever for the automatic transmission is located
on the console between the seats.
Maximum engine speed is limited when the vehicle is in
PARK (P) or NEUTRAL (N) to protect driveline
components from improper operation.
There are several different positions for the shift lever.
When using the Manual Shift Mode (MSM), a number
indicating the gear selected will appear on the
instrument cluster below the shift position display. For
more information on the manual shift option see “Manual
Shift Mode” in this section.PARK (P):This position locks the front wheels. It is the
best position to use when the engine is started
because the 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) on
page 2-33. If you are pulling a trailer, see
Towing a Trailer on page 4-32.
Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an automatic
transmission shift lock control system.
2-28

You must fully apply your regular brakes rst and then
press the shift lever button, before you can shift
from PARK (P) when the ignition is in RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
lever and push the shift lever all way into PARK (P)
as you maintain brake application. Then press the shift
lever button and move the shift lever into another
gear. SeeShifting Out of PARK (P) on page 2-35.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-21.NEUTRAL (N):In this position, the engine does not
connect with the wheels. To restart when the vehicle is
already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while the 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 running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
2-29

2. Push the shift lever forward toward the plus (+) to
upshift or rearward toward the minus (−)to
downshift.
When using the Manual Shift Mode (MSM) the
number of the gear selected will appear on
the instrument cluster below the shift position
display.
In manual shift mode all six forward gears can be
selected.
While using the MSM feature the vehicle will have
operation similar to a manual transmission. You can use
this for sport driving or when driving hilly roads to
stay in gear longer or to downshift for more power or
engine braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed:
The transmission will not automatically shift to the
next higher gear without moving the shift lever.
The transmission will not allow shifting to the next
lower gear if the vehicle speed is too high.
If the vehicle does not respond to a gear change, or
detects a problem with the transmission, the range
of gears may be reduced and the Malfunction Indicator
Lamp will come on. SeeMalfunction Indicator Lamp
on page 3-36.
Transmission Overheating
If the transmission uid temperature rises above
270°F (132°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-35for
more information. When the transmission overheats
it will go into a protection mode and will default into a
different shift sequence to help cool the transmission
uid. This shift sequence is the same for both DRIVE (D)
position and manual mode. Continue driving the
vehicle in either position depending on the required
vehicle speed and load. Once the uid temperature
lowers to the normal temperature range, the
transmission will return to the normal shift patterns.
Towing or driving on long hills can cause the
transmission uid temperature to be higher than normal.
If the transmission uid temperature will not cool, you
may need to pull over and check the transmission
uid level. You should also check the engine coolant
temperature. If it is hot, seeEngine Overheating
on page 5-25.
2-31

To release the parking brake, hold the brake pedal
down. Pull the parking brake lever up until you can press
the release button. Hold the release button in as you
move the brake lever all the way down.
Make sure to release the parking brake before driving
the vehicle.
If the parking brake is applied and the vehicle is moving
at least 4 mph (6 km/h), a chime will activate to
remind you to release the parking brake.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.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 4-32.
1. Hold the brake pedal down with your foot and set
the parking brake. SeeParking Brake on page 2-32
for more information.
2. Move the shift lever into PARK (P) by pressing 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/OFF.
4. Remove the key and take it with you. If you can
leave your vehicle with the key, your vehicle is in
PARK (P).
2-33

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 pressing
the button on the console shift lever. If you can, it
means that the shift lever was not fully locked into
PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. 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 2-33.
When you are ready to drive, move the shift lever out of
PARK (P) before you 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 transmission, so
you can pull the shift lever out of PARK (P).
