Compass display
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antenna. Magnetic
or metallic objects placed in, on or near the vehicle may also affect
compass accuracy.
Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. Refer toCompass zone/calibration
adjustmentin this section.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four

9. Slowly drive the vehicle in a
circle (less than 3 mph [5 km/h])
until the CIRCLE SLOWLY TO
CALIBRATE indicator changes to
CALIBRATION COMPLETED. This
will take up to three circles to complete calibration.
10. The compass is now calibrated.
Average fuel economy (AFE)
Select this function from the INFO
menu to display your average fuel
economy in miles/U.S. gallon or
liters/100 km.
If you calculate your average fuel
economy by dividing gallons of fuel used by 100 miles traveled
(kilometers traveled by liters used), your figure may be different than
displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
•Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET control after setting the speed
control to get accurate highway fuel economy readings.
Average fuel economy for FFV-equipped vehicles
Upon refueling, your vehicle needs to determine the percentage of
Ethanol in the fuel. For the first several minutes, or few miles of driving,
the message “COMPUTING FUEL” may appear in the message center.
The correct fuel economy will appear in the message center following
calculation.

Trip elapsed drive time
Select this function from the INFO
menu to display a timer.
To operate the Trip Elapsed Drive
Time perform the following:
1. Press and release RESET in order
to start the timer.
2. Press and release RESET to pause the timer.
3. Press and hold RESET for 2 seconds in order to reset the timer.
Distance to empty (DTE)
Selecting this function from the
INFO menu estimates approximately
how far you can drive with the fuel
remaining in your tank under
normal driving conditions.
Remember to turn the ignition OFF
when refueling to allow this feature to correctly detect the added fuel.
The DTE function will display LOW FUEL LEVEL and sound a tone for
one second when you have approximately 50 miles (80 km) to empty. If
you RESET this warning message, this display and tone will return
within 10 minutes.
DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 500 miles (800 km). This value is not
the same as the average fuel economy display. The running average fuel
economy is reinitialized to a factory default value if the battery is
disconnected.
Distance to empty for FFV-equipped vehicles
Upon refueling, your vehicle needs to determine the percentage of
Ethanol in the fuel. For the first several minutes, or few miles of driving,
the message “COMPUTING FUEL” may appear in the message center.
The correct distance to empty will appear in the message center
following calculation.

The sequence of the system check report and how it appears in the
message center is as follows:
1. FUEL LEVEL
2. WASHER FLUID LEVEL
3. OIL LIFE IN XX%
4. ADVTRAC
5. ENGINE TEMP
6. OIL PRESSURE
7. TIRE PRESSURE SYSTEM (if equipped)

Warning messages that have been reset are divided into three categories:
•They will reappear on the display every minute from the reset.
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
This acts as a reminder that these warning conditions still exist within
the vehicle.

TIRE PRESSURE MONITORING SYSTEM (TPMS)(IF EQUIPPED)
When the Tire Pressure Monitoring
System warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper pressure as indicated on the vehicle’s tire
information placard (label). Driving on a significantly under-inflated tire
causes the tire to overheat and can eventually lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability. Even if your vehicle is
equipped with a Tire Pressure Monitoring System, it is still important
that you manually check the inflation pressure of your tires regularly.
Each tire, including the spare, should be checked monthly when cold and
set to the recommended inflation pressure which can be found on either
the Safety Compliance Certification Label which is located on the B-Pillar
or the edge of the driver’s door.
The Tire Pressure Monitoring System is NOT a substitute for
manually checking tire pressure. The tire pressure should be
checked periodically (at least monthly) using a tire gauge, see
Inspecting and inflating your tiresin this chapter. Failure to
properly maintain your tire pressure could increase the risk of tire
failure, loss of control, vehicle rollover and personal injury.
Changing tires with TPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.Each road
tire is equipped with a tire
pressure sensor mounted on the
wheel inside the tire connected
to the valve stem. The tire
pressure sensor must be
unbolted from the wheel prior to
tire removal. The sensor can be
removed by loosening the nut at the valve stem. Failure to
remove the sensor may damage it.The rubber grommet (washer)
between the wheel and the tire pressure sensor needs to be replaced
whenever the sensor is removed to minimize air leaks.
