4-34 Instruments and Controls
Trip Computer
The vehicle may have a trip
computer. The trip computer
provides information on driving data.
This information is continually
recorded and evaluated
electronically. If power has been
interrupted or if the battery voltage
has dropped too low, the values
stored in the trip computer will
be lost.
To access trip computer vehicle
data, do one of the following:
•
Press the BC button on the audio
system.
•
Press the left thumbwheel, if your
vehicle has this feature, on the
steering wheel.
Once an audio function has been
selected, the rows of the trip
computer function are displayed.
The functions are displayed in the
following order:
Instantaneous Consumption
This display shows the current fuel
economy at a particular moment and
will change frequently as driving
conditions change. This display
shows the instantaneous fuel
economy in miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
The metric display changes
depending on speed:
•
Below 8 mph (13 km/h),
displays in l/h.
•
Above 8 mph (13 km/h),
displays in l/100 km.
This screen cannot be reset.
Average Consumption
This display shows the approximate
average miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
This number is calculated based on
the number of mpg (l/100 km)
recorded since the last time this
menu item was reset.
The measurement can be reset to
zero at any time and restarted.
See "Reset" later in this section.

gallons (gal) or liters (l) of fuel
used since the last reset.
The measurement can be reset to
zero at any time and restarted.
See "Reset" later in this section.
Average Speed
This display shows the average
speed of the vehicle in miles
per hour (mph) or kilometers per
hour (km/h). This average is
calculated based on the various
vehicle speeds recorded since the
last reset of this value.
The measurement can be reset to
zero at any time and restarted.
