If you calculate your average fuel economy by dividing distance traveled
by gallons of fuel used (liters of fuel used by 100 kilometers traveled),
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)
To determine your average highway fuel economy, do the following:
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 SELECT/RESET stem (press and hold for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
XX°F / XX°C
The outside air temperature is shown together with the compass heading
in the bottom row of the message center display. Refer to
Units
in this
section for information on selecting °F or °C.
COMPASS DISPLAY (if equipped)
The compass heading is displayed as one of N, NE, E, SE, S, SW, W and
NW in the message center 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 to
Compass zone adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is up
to four degrees between adjacent zones and will become noticeable as
the vehicle crosses multiple zones. A correct zone setting will eliminate
this error. Refer to
Compass calibration adjustment.
