2010 PONTIAC G6 Owners Manual

Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicle
with an engine coolant heater should be plugged in at
least four hours before starting. An internal thermostat in
the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures above
0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. On
the 2.4L L4 ECOTEC
®engine, the engine coolant
heater cord is located near the air cleaner box
on the passenger’ side of the engine compartment.
On the 3.5L, 3.6L and 3.9L V6 engines, the
engine coolant heater cord is located on the driver
side around the battery box. SeeEngine
Compartment Overview on page 6-16for more
information on location.3. Plug the cord into a normal, grounded 110-volt
AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
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 and prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking your vehicle for the
best advice in this.

Automatic Transmission Operation
The vehicle will have one of these styles of shifter
located in the center console between the seats.P (Park):This position locks the front wheels. It is the
best position to use when starting the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park (Automatic Transmission) on page 3-30.If
you are pulling a trailer, seeTowing a Trailer on
page 5-27.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must apply
the regular brake first, then press the shift lever
3-24

button before shifting from P (Park) while the ignition
key is in ON/RUN. If you cannot shift out of P (Park),
ease pressure on the shift lever and push the shift lever
all the way into P (Park) as you maintain brake
application. Press the shift lever button and then move
the shift lever into another gear. SeeShifting Out of
Park on page 3-31later in this section.
R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the 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 5-17.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving. It
provides the best fuel economy. If you need more
power for passing, and you are:
•Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
•Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 5-10.
3-25

Notice:If your vehicle seems to accelerate slowly
or not shift gears when you go faster, and you
continue to drive your vehicle that way, you could
damage the transmission. Have your vehicle
serviced right away. You can drive in L (Low) when
you are driving less than 35 mph (56 km/h) and
D (Drive) for higher speeds until then.
3 (Third):This position is also used for normal driving.
However, it reduces vehicle speed more than D (Drive)
without using the brakes. Here are some times you
might choose 3 (Third) instead of D (Drive):
•When driving on hilly, winding roads.
•When towing a trailer, so there is less shifting
between gears.
•When going down a steep hill.
L (Low):This position reduces vehicle speed more
than 3 (Third) without using the brakes. You can
use L (Low) on hills. It can help control vehicle speed
going down steep mountain roads along with using
the brakes off and on.
You can use L (Low) on very steep hills, in deep snow
or mud. If the shift lever is in L (Low), the transmission
will not shift into first gear until the vehicle is going
slowly enough.Notice:Driving in LOW (L) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
LOW (L) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of LOW (L).
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 the vehicle warranty. If you
are stuck, do not spin the tires. When stopping on a
hill, use the brakes to hold the vehicle in place.
M (Manual Mode):This position allows you to change
gears similar to a manual transmission. If the vehicle
has this feature, see Manual Shift Mode (MSM)
following.
Manual Shift Mode (MSM) (If Equipped)
To use this feature,
1. Move the shift lever from D (Drive) rearward into
the M (Manual Mode).
While driving in manual mode, the transmission will
remain in the driver selected gear.
2. Press the shift lever forward to upshift or rearward
to downshift.
3-26

The odometer display on the instrument panel cluster
will change from vehicle mileage to the letter M,
for manual shift mode, and a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 4-26for more information.
While using the MSM feature the vehicle will have firmer
shifting and sportier performance. You can use this
for sport driving or when climbing hills 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 and engine revolutions
per minute (RPM):
•The transmission will not shift to the next higher
gear if the engine RPM is too low.
•The transmission will not allow shifting to the next
lower gear if the engine RPM 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 4-34for more information.
Driver Shift Control (DSC) (If Equipped)
To use this feature,
1. Move the shift lever from DRIVE (D) rearward to
MANUAL (M).
While driving in manual mode, the transmission will
remain in the driver selected gear. When coming
to a stop in the manual position, the vehicle
will automatically shift into FIRST (1) gear.
2. Press the + (plus) paddle located on top of the
steering wheel controls forward to upshift, or
push the backside of the shift paddle rearward to
downshift.
3-27

The odometer display on the instrument panel cluster
will change from the vehicle’s mileage to the letter M for
Manual Shift Mode, and a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 4-26for more information.
While using the DSC feature the transmission will have
firmer shifting and sportier performance. You can
use this for sport driving or when climbing hills 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 and engine revolutions
per minute (RPM):
•The transmission will not automatically shift to the
next higher gear if the vehicle speed or engine
RPM is too high.
•The transmission will not allow shifting to the next
lower gear if the vehicle speed or engine RPM is
too high.
2 (Second)/3 (Third) Gear Start Feature
Notice:If you attempt a third gear start while
trailering or towing a heavy load, you will notice
reduced engine power. This could overheat
and damage your transmission. Do not attempt a
third gear start while trailering or towing your
vehicle.
Vehicles with a 6-speed transmission allow 2 (Second)
and 3 (Third) gear starts. When accelerating the
vehicle from a stop in snowy and icy conditions, you
may want to shift into 2 (Second), or 3 (Third) gear. A
higher gear, and light application of the gas pedal, may
allow you to gain more traction on slippery surfaces.
With the MSM, the vehicle can accelerate from a stop in
2 (Second) or 3 (Third).
1. Move the shift lever from D (Drive) into the
M (Manual Mode) position.
2. With the vehicle stopped, move the lever forward
towards the + (plus) to select 2 (Second) or
3 (Third) gear. The vehicle will start from a stop
position in 2 (Second) or 3 (Third) gear.
3. Once the vehicle is moving select the desired
drive gear.

Shifting Into Park (Automatic
Transmission)
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the 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 5-27.
Use this procedure to shift into P (Park):
1. Hold the brake pedal down and set the parking
brake.
SeeParking Brake on page 3-29for more
information.
2. Move the shift lever into P (Park) by holding in 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 the vehicle with the ignition key in your
hand, the vehicle is in P (Park).
Leaving Your Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) with the parking
brake firmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch fire. You or others could be injured. Do not
leave the vehicle with the engine running.
If you have to leave the vehicle with the engine running,
be sure the vehicle is in P (Park) and the parking
brake is firmly set before you leave it. After you have
moved the shift lever into P (Park), hold the brake pedal
down. Then, see if you can move the shift lever away
from P (Park) without first pushing the button.
If you can, it means that the shift lever was not fully
locked into P (Park).
