Trip computer
Introduction
Applies to vehicles: wit h trip computer
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Tri p comp uter d isp lay: Ave rage fuel mileage
The follow ing informat ion is continuously
evaluated by the trip computer and can be dis­
p layed sequentially in the instrument cluster
display:
Fuel range
The estimated cruising range in miles (km)
appears in the display. This tells you how far
your vehicle wi ll be able to t ravel on the cur ­
rent tank of fue l and with the same driving
style. The display changes in increments of
5 miles (10 km).
The cruising range is calculated based on the
fuel consumption for the last 18 miles
(30 km). If you drive conservatively, the cruis­
ing range will increase.
Average fuel mileage
The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this disp lay to adjust
your driving technique to achieve a desired mileage .
Current fuel mileage
The instantaneous fuel consumption in miles
per gallon (l/100 km) is shown in this display .
You can use this display to adjust your driving
technique to achieve a desired mileage. Fuel
consumption is recalcu lated at intervals
of 33 yards (30 meters). This disp lay switches
to gallons/hour (liters/hour) when the vehicle is not moving.
Average speed
The average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that you have been driving
s ince you last reset the memory appears in
th is disp lay.
Distance
The distance that has been covered since the
last t ime the memory was cleared appears in
the display.
(0 Tips
- Fuel consumptions (average and cur ­
rent), range and speed are displayed in
metric units on Canadian models.
- All stored values will be lost if the vehi­
cle battery is disconnected .
Memories
Applies to veh icles: w ith t rip co mputer
The trip computer is equipped with two fully
automatic memories as well as an efficiency
program* .
