2010 PONTIAC G6 trailer

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast
or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Do not exceed
5,000 engine rpm. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 5-27for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
The ignition switch has
four different positions.
Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or
break the key. Use the correct key, make sure it is
all the way in, and turn it only with your hand. If the
key cannot be turned by hand, see your
dealer/retailer.
9(LOCK/OFF):This is the only position from which
you can remove the key. The shift lever must be in
P (Park) with the ignition in LOCK/OFF to remove
the key.

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

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 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.

Parking Brake
To set the parking brake, pull up on the parking brake
handle. If the ignition is on, the brake system warning
light will come on. SeeBrake System Warning Light on
page 4-30.To release the parking brake:
1. Hold the brake pedal down.
2. Pull the parking brake handle up until you can
press the release button.
3. Hold the release button in as you move the brake
handle all the way down.
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.
If you are towing a trailer and you are parking on a hill,
seeTowing a Trailer on page 5-27.

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).

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 3-32.
{WARNING:
It can be dangerous to get out of the vehicle if the
automatic transmission 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).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park (Automatic Transmission)
on page 3-30.
If parking on a hill and pulling a trailer, seeTowing a
Trailer on page 5-27.

Parade Dimming
Parade mode automatically prohibits the dimming of the
instrument panel displays during the daylight while
the headlamps are on so that the displays are still able
to be seen.
Reading Lamps
For vehicles with front and rear reading lamps, press
the lens to turn the lamp on and off, while the doors are
closed. These lamps come on automatically when
any door is opened.
Trunk Lamp
The trunk lamp comes on when the trunk is opened and
turns off when the trunk is closed.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of
charge. It then adjusts the voltage for best performance
and extended life of the battery.When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage move
up or down. This is normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
