start stop button PONTIAC G8 2008 Owners Manual

ease pressure on the shift lever and
push the shift lever all the way
into P (Park) while maintaining brake
application. Then press the shift
lever button and move the shift lever
into another gear. SeeShifting
Out of Park on page 8-11.
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.
R (Reverse):Use this gear to
back up.
At low vehicle speeds, R (Reverse)
can also be used 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 8-27for additional information.N (Neutral):In this position, the
engine does not connect with
the wheels. To restart when the
vehicle is already moving, use
N (Neutral) only.
{CAUTION
Shifting into a drive gear while
the engine is running at high
speed is dangerous. Unless
your foot is rmly 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 from the vehicle.
If more power is needed for passing,
and the vehicle is:
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.
The transmission will shift down
to a lower gear and have
more power.
Downshifting the transmission in
slippery road conditions could result
in skidding, see Skidding under
Loss of Control on page 8-21.
Notice:Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. If you are stuck,
do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.

When accelerating the vehicle from
a stop in snowy and icy conditions,
1st, 2nd or 3rd gear starts can
be selected from a standing start.
This is useful for gentle acceleration
on slippery surfaces.
To return to Normal Shift mode,
slide the shift lever over from
the right quadrant to the left into
D (Drive). A Normal Shift message
will be displayed in the DIC.
Normal Shift Mode is recommended
for normal or freeway driving, as
it provides optimum fuel economy.
Powertrain Braking
For vehicles with a 6 speed
automatic transmission, there is
an additional feature known
as Powertrain Braking. When driving
on steep descents where frequent
braking is required, the vehicle
will automatically downshift to
provide engine braking assistance.
This feature also reduces brake
temperatures and wear.Downshifting will only occur when
the driver’s foot is applied to the
brake. Driver Shift Control can
be switched on to override the
feature and gain complete control
of shifts if desired.
Parking Brake
To set the parking brake, pull up on
the parking brake handle. If the
ignition is in the ON/RUN position,
the brake system warning light
will come on. SeeBrake System
Warning Light on page 4-16.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.
Driving with the park brake applied
will cause a warning chime to
sound and the Park Brake message
to appear in the DIC. The message
will remain on until:
the park brake is released
the vehicle comes to a stop.
If you are towing a trailer and you
are parking on a hill, seeTowing a
Trailer on page 9-85.

If the TPMS is not functioning it
cannot detect or signal a low
tire condition. See the dealer/retailer
for service if the TPMS malfunction
light and DIC message comes
on and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identication code. Any time one or
more of the TPMS sensors are
replaced or the vehicle’s tires are
rotated, the identication codes
need to be matched to the
new tire/wheel location. The sensors
are matched, to the tire/wheel
locations, in the following order:
driver side front tire, passenger side
front tire, passenger side rear
tire, and driver side rear tire using a
TPMS diagnostic tool. See your
dealer/retailer for service.The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. When increasing
the tire’s pressure, do not exceed
the maximum ination pressure
indicated on the tire’s sidewall. To
decrease the tire’s air-pressure
use the pointed end of the valve
cap, a pencil-style air pressure
gage, or a key.
You have two minutes to match
each tire and wheel position.
If it takes longer than two minutes to
match any tire and wheel position,
the matching process stops and you
need to start over.The TPMS matching process is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press and hold the Remote
Keyless Entry (RKE) transmitter’s
lock and unlock buttons, at the
same time, for about ve seconds
to start the TPMS learn mode.
The horn chirps two times
indicating the TPMS receiver is
ready and in learn mode.
4. Start with the driver side front
tire. The driver side front
indicator lamp also comes on to
indicate that corner’s sensor
is ready to be learned.
5. Remove the valve cap from the
tire’s valve stem. Activate the
TPMS sensor by increasing
or decreasing the tire’s air
pressure for about eight seconds.
The horn chirps one time to
conrm the sensor identication
code has been matched to
the tire/wheel position.
