2008 PONTIAC G8 ECO mode

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.

6. The driver side front indicator
lamp turns off and the
passenger side front indicator
lamp comes on to indicate
that corner’s sensor is ready to
be learned. Proceed to the
passenger side front tire and
repeat the procedure in Step 5.
7. The passenger side front
indicator lamp turns off and the
passenger side rear indicator
lamp comes on to indicate that
corner’s sensor is ready to
be learned. Proceed to the
passenger side rear tire and
repeat the procedure in Step 5.
8. The passenger side rear indicator
lamp turns off and the driver side
rear indicator lamp comes on to
indicate that corner’s sensor is
ready to be learned. Proceed to
the driver side rear tire, and
repeat the procedure in Step 5.9. After the driver side rear TPMS
sensor has been learned the
horn chirps two times. The driver
side rear indicator lamp turns
off and the TPMS sensor
matching process is done. Turn
the ignition switch to LOCK/OFF.
If no tires are learned after
entering the TPMS learn mode,
or if communication with the
receiver stops, or if the time limit
has expired, turn the ignition
switch to LOCK/OFF and
start over beginning with Step 2.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, for
signs of wear or damage.
SeeWhen It Is Time for New
Tires on page 9-56for more
information.
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). SeeScheduled
Maintenance on page 11-4.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that your vehicle
continues to perform most like it
did when the tires were new.
