2010 PONTIAC G6 engine

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.

Notice:Forcing the sunshade forward of the
sliding glass panel may cause damage and the
sunroof may not operate properly. Always close the
glass panel before closing the sunshade.
Do not leave the sunroof open for long periods of time.
Debris can collect in the tracks and possibly damage
the sunroof operation and plug the water draining
system.
Retractable Hardtop
The following procedures explain the proper operation
of the retractable hardtop. The retractable hardtop
will not operate if the trunk cargo cover is not in place.
If the retractable hardtop is lowered or raised multiple
times, the engine should be running while doing
so to prevent drain on the vehicle’s battery.
Lowering the Retractable Hardtop
Notice:Leaving the retractable hardtop down and
exposing the interior of the vehicle to outdoor
conditions may cause damage. Always close the
retractable hardtop if leaving the vehicle outdoors.
Notice:Lowering the top if it is damp, wet, or
dirty can cause stains, mildew, and damage to the
inside of your vehicle. Dry off the top before
lowering it.Notice:If you lower the retractable hardtop in cold
weather (32°F/0°C or lower), you may damage
top components. Do not lower the retractable
hardtop in cold weather.
1. Park on a level surface, and shift the transmission
into P (Park). The vehicle must be in P (Park), and
the engine must be running, or the ignition
turned to the ON/RUN position, to operate the
retractable hardtop.
2. The trunk cargo cover must be fully closed, and the
trunk must be closed before lowering the hardtop.
3. There should be nothing on top, in front of or around
the hardtop or cargo cover.
3-38

The windows and trunk lid will open. The hardtop will
automatically lower, and the trunk lid will close and latch.
If the engine is on, a chime will sound when the
hardtop has lowered completely. The Driver Information
Center (DIC) will display TOP MOVE COMPLT. See
DIC Warnings and Messages on page 4-42for
more information.After the hardtop has lowered completely, release the
switch. If you continue to press the switch for about
two seconds after the hardtop has completely lowered,
the windows will automatically close.
If pressure is released from the switch before the
hardtop cycle is complete, the cycle will stop and the
Driver Information Center (DIC) will display the
TOP NOT SECURE message. Always press and hold
the switch until a chime sounds, if the engine is on, and
the Driver Information Center (DIC) displays the TOP
MOVE COMPLT to signal the procedure is complete.
SeeDIC Warnings and Messages on page 4-42
for more information.
When the retractable hardtop is down and stowed in the
trunk, the trunk open function will be disabled. When
the ignition is on, the TRUNK NOT ALLOW message will
be displayed on the DIC when attempting to open the
trunk with the retractable hardtop stowed inside.
SeeDIC Warnings and Messages on page 4-42for
more information.

Raising the Retractable Hardtop
1. Park on a level surface, and shift the transmission
into P (Park). The vehicle must be in P (Park), and
the engine must be running, or the ignition
turned to the ON/RUN position, to operate the
retractable hardtop.
2. The trunk cargo cover must be fully closed, and the
trunk must be closed before raising the hardtop.
3. Make sure nothing or no one is on or around the
hardtop. Make sure there is no cargo on top of or
in front of the trunk cargo cover.{WARNING:
When the retractable hardtop is opened or closed,
people can be injured by the parts that move: the
hardtop and its mechanism, the trunk lid, and the
side windows. Keep people away from these parts
when you are lowering or raising the top.
{WARNING:
If the retractable hardtop is not completely opened
or closed, the system will cause the retractable
hardtop to slowly descend after 3 minutes. You or
others could be injured. The retractable hardtop
will descend immediately if the ignition is turned to
LOCK/OFF during the opening or closing of the
retractable hardtop. Always completely open or
close the retractable hardtop and do not shut off
the ignition during the opening or closing of the
retractable hardtop.

4. The hardtop switch is located on the headliner.
To raise the hardtop, pull and hold the switch until the
cycle is complete.As the switch is being pulled the hardtop will raise from
the trunk and move into place. The hardtop and
trunk lid will close and latch. If the engine is on, a chime
will sound when the hardtop has raised completely.
The Driver Information Center (DIC) will display the TOP
MOVE COMPLT message to signal the procedure is
complete. SeeDIC Warnings and Messages on
page 4-42for more information.
3-42

After the hardtop has raised completely, release the
switch. If you continue to pull the switch for about
two seconds after the hardtop has raised completely,
the windows will automatically close.
If the switch is released before the hardtop cycle is
complete, the cycle stops and the Driver Information
Center (DIC) displays the TOP NOT SECURE message.
Always pull and hold the switch until a chime sounds,
if the engine is on, and the Driver Information Center
(DIC) displays the TOP MOVE COMPLT to signal
the procedure is complete. SeeDIC Warnings and
Messages on page 4-42for more information.The hardtop will not operate if the vehicle has an
electrical failure. If an electrical failure occurs,
see your dealer/retailer for service.
If your vehicle must be towed to a dealer/retailer for
service, your vehicle should be towed by flatbed with the
vehicle facing backwards. Consult your dealer/retailer
or professional towing service if you need to have
your disabled vehicle towed. SeeRoadside Assistance
Program on page 8-7.

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.
