Trip computer
Introduction
The trip computer gives you information on current and
average fuel mileage, average speed, fuel range and
driving time.
F ig . 2 1 Trip co m pute r
d is pl ay : Ave ra ge fuel
mil eag e
The fol lowing driving information is continuously evaluated by the
trip computer and can be displayed sequentially in the instrument
cluster display .
Fuel range
The estimated cruising range in miles (km) appears in the display .
T his tells you how far your vehic le will be ab le to travel on the _.,

current tank of fuel and with the same driving style. The display
changes in increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
the last 18 miles (30 kml. If you drive conservatively, the cruising
range will increase.
Average fuel mileage
The average fuel economy in MPG (1/100 km) since you last c leared
the memory appears in this display . You can use this display to
adjust your driving technique to achieve a desired mileage.
Current fuel mileage
The instantaneous fuel consumption in miles per gallon (1/100 km)
is shown in this display. You can use this display to adjust your
driving technique to achieve a desired mileage.
Fuel consumption is recalculated at intervals of 33 yards (30
metres). When the vehic le is sta tionary, the most recent fuel
consumption is displayed.
Average speed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
Elapsed time
The length of time that you have been driving since you last reset
the memory appears in this display.
[ i ] Tips
• Fuel consumptions (average and current) , range and speed are
displayed in metric units on Canad ian models .
• All stored values wil l be lost if the vehicle battery is
disconnected .•
Con tro ls and eq uip­

Driver information display
Memori es
The trip computer is equipped with two fully automatic
memones.
Fig . 22 Trip computer
display: memory level 1
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ ~ page 40, fig. 23.
You can tell which memory level is currently active by the number in
the display ~ fig . 22. The data from the single -trip memory
(memory level 1) is being displayed if a
1 appears . If a 2 is shown ,
then the data from the total -trip memory is being disp layed
(memory level 2).
Single-trip memory (Trip computer 1 )
The single-trip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the trip is continued
within 2 hours from the time the ignition was turned off, the new
data will be included in the calculation of the current trip informa­
tion. If the trip is interrupted for
more than 2 hours the memory is
reset automatically.
Total-trip memory (Trip computer 2)
Unlike the single -trip memory, the total -trip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manual resets .•
Vehicle care I I irechnical data

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) * and fully loaded vehicles .

Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitations

Dri
ving and environm ent
If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumption by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketbook.
[ i ] Tips
The consumption estimates as published by ENV IRONMENTAL
PRO TEC TION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
-Avoid unnecessary accelerat ing and braking.
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car 's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by
