Performance and
Maintenance
®
StabiliTrak System
If equipped, the vehicle has a
traction control system that limits
wheel spin and the StabiliTrak
system that assists with directional
control of the vehicle in difficult
driving conditions. Both systems
turn on automatically every time the
vehicle is started.
To turn off traction control, press
and release on the instrument
panel. The appropriate DIC
message displays. See Ride
Control System Messages on
page 5 44.
To turn off both traction control
and StabiliTrak, press and
hold until illuminates and
the appropriate DIC message
displays. See Ride Control
System Messages on page 5 44.
Press and release again to
turn on both systems.
For more information, see
®
StabiliTrak System on page 9 55.
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9 16. The warning
light will remain on until the tire
pressure is corrected.
I n f o r ma t i o n P r o v i d e d b y :
In Brief
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early
indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10 60.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, displays a
DIC message when it is necessary
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
