Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Trip computer display: Average fuel mileag e
The following information is continuously
eva luated 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 travel on the cur
rent tank of fue l and with the same driving
style. The display changes in increments of 6
miles (10 km).
The cruising range is calcu lated based on the
fuel cons umption for the last 18 mi les
(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 adj ust yo ur driving
technique to ach ieve a desired mileage.
Driver information display 25
Fuel consumption is recalcu lated at intervals
of 33 yards (30 meters). This display switches
to gallons/hour (liters/hour) when the veh icle
is not moving.
Average speed
T he average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that yo u 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 time the memory was cleared appears in
the d isplay .
(0 Tips
- Fuel consumptions (average and cur rent), range and speed are displayed in
metric units on Canadian mode ls.
- All stored values will be lost if the vehi
cle battery is disconnected.
Memories
The trip computer is equipped with two fully
automatic memories.

Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold eng ine.
The engine and catalyt ic converter have to
reach their optimal
operat ing tempe ratu re to
reduce fuel consumption and noxious emis
sions effect ively .
Just after starting, a cold engine in a mid-size
car only achieves a f uel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 m iles (4 km),
the eng ine is at its proper operat ing tempera
ture and fue l economy has reached a no rma l
l eve l. So you can see that you sho uld avoid
short tr ips wheneve r possib le .
The
o ut sid e temp era ture is also critical in this
r egard. Your car consumes more fuel in the
winter than in the summer.
