2008 Pontiac G6 Owner ManualM

THIRD (3):This position, available on the SE model, is
also used for normal driving. However, it reduces
vehicle speed more than DRIVE (D) without using your
brakes. Here are some times you might choose
THIRD (3) instead of DRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
LOW (L):This position, available on the SE model,
reduces vehicle speed more than THIRD (3) without
using your brakes. You can use LOW (L) on hills. It can
help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
You can use LOW (L) 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 rst 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 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.
MANUAL MODE (M):This position, available on the
GT/GXP models, allows you to change gears similar to a
manual transmission. If your vehicle has this feature,
see Manual Shift Mode (MSM) following.
Manual Shift Mode (MSM) (Automatic
Transmission)
To use this feature, do the following:
1. Move the shift lever from DRIVE (D) rearward and
then to the right into the MANUAL MODE (M).
While driving in manual shift mode, the transmission
will remain in the driver gear selected.
2. Press the shift level forward to upshift or rearward
to downshift.
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 3-29for more information.

As an added safety feature, if the wipers are on for
more than 15 seconds, the vehicle’s headlamps turn
on automatically. They turn off 15 seconds after
the wipers are turned off.
Windshield Washer
To wash the windshield, press the button at the end of
the lever until the washers begin.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
When the button is released, the washers stop, but the
wipers continue to wipe about three times or resume
the previous speed.
Cruise Control
If your vehicle has cruise control, a speed of about
25 mph (40 km/h) or more can be maintained without
keeping your foot on the accelerator. This can really help
on long trips. Cruise control does not work at speeds
below 25 mph (40 km/h).
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.

To avoid blowing cold air at start-up in cold weather,
the system delays turning on the fan until warm air is
available. The length of delay depends on the engine
coolant temperature. Turning the fan knob overrides
this delay and change the fan to a selected speed.
If your vehicle has the remote start feature, the climate
control display initially shows “AS” in place of the
temperature to indicate the remote start has been
activated. The remote start system turns on using the
last temperature selected before the vehicle was
last turned off.
For best performance, turn the fan and mode knobs to
the AUTO position. The fan speed and air delivery
modes will change to achieve the best comfort.
If the outside air temperature is below 45°F and the air
delivery mode knob is set to AUTO, the automatic
climate control system starts in the defrost mode to clear
the window.
The automatic climate control changes back to manual
operation by turning the vehicle on with the key.
Manual Operation
The air delivery mode or fan speed can be manually
adjusted.
9(Off):Select this position on the fan knob to turn off
the entire climate control system. Outside air still
enters the vehicle, and is directed to the oor.This direction can be changed by changing the mode
position. The temperature can also be adjusted
using either the up or down arrow temperature buttons.
9(Fan):Turn the knob with the fan symbol to
manually adjust the fan speed.
H(Vent):Turn the knob to this position to direct air
to the instrument panel outlets.
)(Bi-Level):Turn the knob to this position to direct
half of the air to the instrument panel outlets, and
the remaining air to the oor outlets.
6(Floor):Turn the knob to this position to direct most
of the air to the oor outlets with some air directed to
the side window outlets and windshield.
The right knob can also be used to select defog or
defrost modes. See Defogging and Defrosting later in
this section.
:(Outside Air):Press the right side of this button
to turn the outside air mode on. Air from outside
the vehicle circulates throughout your vehicle. An
indicator light comes on to show that it is activated. The
outside air mode can be used with all modes, but it
cannot be used with the recirculation mode. Press this
button to cancel the recirculation mode.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, the light comes
on and you hear a chime, the engine is too hot! It means
that your engine coolant has overheated. SeeEngine
Overheating on page 5-33.
Tire Pressure Light
Your vehicle has a tire
pressure light.
This light comes on briey when the engine is started
and provides information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This indicates that one or more of your tires are
signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC), may accompany the light. SeeDIC
Warnings and Messages on page 3-46for more
information. Stop and check your tires as soon as it is
safe to do so. If underinated, inate to the proper
pressure. SeeTires on page 5-60for more information. United States
Canada
3-37

When the Light Flashes First and Then is
Solid
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light will ash for
about a minute and then stay on solid for the remainder
of the ignition cycle. This sequence will repeat with
every ignition cycle. SeeTire Pressure Monitor System
on page 5-70for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
The check engine light
comes on to indicate that
there is an OBD II
problem and service is
required.Malfunctions often are indicated by the system before
any problem is apparent. This can prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly diagnosing
any malfunction.
Notice:If you keep driving your vehicle with this
light on, after a while, the emission controls
might not work as well, your vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This could
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-4.
