2007 PONTIAC GRAND PRIX instrument cluster

TRACTION CONTROL ACTIVE
This symbol comes on
with this message.
If the vehicle has the Traction Control System
(TCS), this message displays when the system is
on. TRACTION CONTROL ACTIVE also
appears in the Head-Up Display (HUD), if your
vehicle has this feature.
This message only displays while the ignition is in
RUN and will not disappear until driving
conditions change and the TCS is no longer
active.
This message cannot be acknowledged or cleared
from the screen.
TRACTION CONTROL OFF
This symbol comes on
with this message.
If the vehicle has the Traction Control System
(TCS), this message displays when the TCS turns
off. TRACTION CONTROL OFF also appears
in the Head-Up Display (HUD), if your vehicle has
this feature. This message only displays while
the ignition is in RUN and disappears after
three seconds. A chime sounds once and the
message stays on for three seconds and
then disappears. A warning light indicating that
this system is deactivated also appears on
the instrument panel cluster. SeeTraction Control
System (TCS) Warning Light on page 178or
Enhanced Traction System Warning Light
on page 179.

Traction Control System (TCS)
If the vehicle has the 3800 Supercharged V6
engine or the 5.3L V8 engine, it 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 works the front brakes and reduces
engine power to limit wheel spin.
This symbol, along with
the TRACTION
CONTROL ACTIVE
message, comes on the
DIC screen when the
system is active.
You may feel or hear the system working, but this
is normal.When the traction control system is not working,
one of these symbols will come on the instrument
panel cluster.
This symbol is located
on the instrument panel
cluster.
This symbol, along with the message TRACTION
CONTROL OFF will display in the DIC for
three seconds when the traction control system
is disabled.

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are under-inated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. If your vehicle has this feature, sensors
are mounted onto each tire and wheel assembly,
except for the spare tire. The TPMS sensors
monitor the air pressure in your vehicle’s tires and
transmit tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol on the instrument panel cluster,
and at the same time a warning message to check
the pressure in a specic tire displays on the
Driver Information Center (DIC). The low
tire pressure warning light and the DIC warning
message CHECK TIRE PRESSURE come
on at each ignition cycle until the tires are inated
to the correct ination pressure.
