If the StabiliTrak/ESC and TCS are off, the
system does not assist in controlling the
vehicle. Turn on the TCS and the StabiliTrak/
ESC systems and the warning light turns off.
SeeTraction Control/Electronic Stability
Control 0214.
Traction Control System (TCS)/
StabiliTrak Light
This light comes on briefly when the vehicle
is turned on.
If the light does not come on, have the
vehicle serviced by your dealer. If the
system is working normally, the indicator
light turns off.
If the light is on and not flashing, the TCS
and potentially the StabiliTrak/ESC system
are not fully operational and may not assist
in maintaining control. Adjust driving
accordingly. If the condition persists, see your dealer as soon as possible. A Driver
Information Center (DIC) message may
display.
The light flashes when the TCS and/or the
StabiliTrak/ESC system is actively working.
See
Traction Control/Electronic Stability
Control 0214.
Tire Pressure Light
For vehicles with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the engine is started. It provides
information about tire pressures and
the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires
are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display. Stop as
soon as possible, and inflate the tires to the pressure value shown on the Tire and
Loading Information label. See
Tire Pressure
0 293.
When the Light Flashes First and Then Is On
Steady
If the light flashes for about a minute and
then stays on, there may be a problem with
the TPMS. If the problem is not corrected,
the light will come on at every ignition
cycle. See Tire Pressure Monitor Operation
0 295.
Engine Oil Pressure Light
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.

graph is the best average fuel economy that
has been achieved for the selected distance.
The selected distance is displayed at the top
of the page as “last xxx mi/km.” Press
Vto
select the distance or reset best value.
The display provides information on how
current driving behavior affects the running
average and how well recent driving
compares to the best that has been
