Performance and
Maintenance
StabiliTrak®System
If equipped, the vehicle has a

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
gon the instrument
panel. The appropriate DIC
message displays. See Ride
Control System Messages on
page 5‑44.

System Messages on page 5‑44.
.Press and releasegagain 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. 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.

Compass
The vehicle may have a compass in
the Driver Information Center (DIC).
Compass Zone
The zone is set to zone eight upon
leaving the factory. Your dealer will
set the correct zone for your
location. Under certain circumstances,
such as during a long-distance,
cross-country trip or moving to a
new state or province, it will be
necessary to compensate for
compass variance by resetting the
zone through the DIC if the zone is
not set correctly.
Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
where you live, the compass may
give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
To adjust for compass variance, use
the following procedure:
Compass Variance (Zone)
Procedure
1. Do not set the compass zone
when the vehicle is moving. Only
set it when the vehicle is in
P (Park).

Press the vehicle information
button until PRESS
VTO
CHANGE COMPASS ZONE
displays. Or, if the vehicle does
not have DIC buttons, press the
trip odometer reset stem until
CHANGE COMPASS ZONE
displays.
2. Find the vehicle's current location and variance zone
number on the map.
Zones 1 through 15 are
available. 3. Press the set/reset button to
scroll through and select the
appropriate variance zone.
4. Press the trip/fuel button until the vehicle heading, for
example, N for North, is
displayed in the DIC. Or, if the
vehicle does not have DIC
buttons, press and hold the
trip odometer reset stem for
two seconds to select the next
available variance zone. Repeat
this step until the appropriate
variance zone is displayed.
5. If calibration is necessary, calibrate the compass. See
“Compass Calibration
Procedure” following.
Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an
open parking lot, where driving the
vehicle in circles is not a danger. It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic
CB or cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle,
move the magnetic item, then turn
on the vehicle and calibrate the
compass.
