2010 PONTIAC G6 automatic transmission

Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system turns on the headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, and the instrument panel
lights. The radio lights will also be dim.
The vehicle has a light sensor on top of the instrument
panel that controls the automatic headlamp system.
Do not cover the sensor or the automatic headlamp
system will turn on when it is not needed.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the automatic
headlamp systems so that driving under bridges or
bright overhead street lights does not affect the system.
The DRL and automatic headlamp systems will only
be affected when the light sensor sees a change
in lighting lasting longer than this delay.
If vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once
the vehicle leaves the garage, it takes about one minute
for the automatic headlamp system to change to DRL
if it is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make sure
the instrument panel brightness control is in the full
bright position. SeeInstrument Panel Brightness
on page 4-13.To idle the vehicle with the automatic headlamp system
off, turn the ignition on and set the exterior light
switch to the off/on position. For vehicles first sold in
Canada, the transmission must stay in P (Park) for this
function.
The regular headlamps should be used when needed.
Fog Lamps
For vehicles with fog lamps, the button for this feature is
located on the instrument panel, to the left of the
steering wheel.
The ignition must be on for the fog lamps to work.
#:Press to turn the fog lamps on or off. An indicator
light comes on when the fog lamps are on.
The parking lamps automatically turn on and off when
the fog lamps are turned on and off.
The fog lamps turn off while the high-beam headlamps
are turned on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

Speedometer and Odometer
The speedometer shows the vehicle speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
When in manual shift mode, the odometer will change
from the vehicle’s mileage to the letter M, for manual
mode, and a number indicating the requested gear
range when moving the shift lever forward or rearward.
For more information seeAutomatic Transmission
Operation on page 3-24.
This vehicle has a tamper resistant odometer.
Repair or replacement of the instrument panel cluster
should only be performed by your dealer/retailer.
Trip Odometer
The trip odometer can display how far the vehicle has
been driven since it was last reset.
For more information seeDIC Operation and Displays
on page 4-40.
Tachometer
The tachometer shows the
engine speed in
revolutions per minute
(rpm).
Notice:If the engine is operated with the
tachometer in the shaded warning area, the vehicle
could be damaged, and the damages would not
be covered by the vehicle warranty. Do not operate
the engine with the tachometer in the shaded
warning area.2.4L and 3.6L Engine

This light comes on if there
is a problem with the
system or the system
has been turned off.
StabiliTrak comes on automatically whenever the
vehicle is started. To help assist with directional control
of the vehicle, the system should always be left on.
The Traction Control System (TCS) and StabiliTrak
can be turned off if needed by pressing and holding
the TCS/ESC button until the StabiliTrak/TCS Off light
comes on. Press the button again to turn StabiliTrak and
Traction Control back on. See Traction Control System
(TCS) following for more information.
If cruise control is being used when the system
activates, cruise control will automatically disengage.
Press the cruise control button to reengage when road
conditions allow. SeeCruise Control on page 4-7for
more information.Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses that one
or both of the front wheels are spinning or beginning to
lose traction. When this happens, the system reduces
engine power and may also upshift the transmission
to limit wheel spin. Also, the traction control system
activates the appropriate corner brakes to gain even
quicker control to limit wheel spin.
The system may be heard or felt while it is working, but
this is normal.
If cruise control is being used when TCS begins to
limit wheel spin, the cruise control will automatically
disengage. Press the cruise control button to reengage
when road conditions allow. SeeCruise Control on
page 4-7for more information.
TCS operates in all transmission shift lever positions
except park or neutral. But the system can upshift the
transmission only as high as the shift lever position that
is chosen, so use the lower gears only when necessary.
SeeAutomatic Transmission Operation on page 3-24.

Here are some important things to consider before
recreational vehicle towing:
•What’s the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer’s
recommendations.
•How far will the vehicle be towed? Some vehicles
have restrictions on how far and how long they
can tow.
•Does the vehicle have the proper towing
equipment? See your dealer/retailer or trailering
professional for additional advice and equipment
recommendations.
•Is the vehicle ready to be towed? Just as preparing
the vehicle for a long trip, make sure the vehicle is
prepared to be towed. SeeBefore Leaving on a
Long Trip on page 5-13.
Dinghy Towing From the Front
If the vehicle has the 3.9L V6 engine with the four-speed
automatic transmission, the vehicle cannot be dinghy
towed.
If the vehicle does not have the 3.9L V6 engine with a
four-speed automatic transmission, it can be dinghy
towed.When dinghy towing the vehicle, the vehicle should be
run at the beginning of each day and at each RV fuel stop
for about five minutes. This will ensure proper lubrication
of transmission components.
For vehicles that can be dinghy towed with all four
wheels on the ground:
1. Position the vehicle to tow and then secure it to the
towing vehicle.
2. Shift the transmission to P (Park) and turn the
ignition to LOCK/OFF.
5-24

If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
brake pedal until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking
brake and shift the transmission into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
•start the engine,
•shift into a gear, and
•release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. SeeScheduled Maintenance on page 7-3for more
information. Things that are especially important in trailer
operation are automatic transmission fluid, engine oil,
belts, cooling system and brake system. It is a good idea
to inspect these before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating
on page 6-35.
Changing a Tire When Trailer Towing
If the vehicle gets a flat tire while towing a trailer,
be sure to secure the trailer and disconnect it from
the vehicle before changing the tire.

Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 6-16
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done,
the oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.
