On-board computer
You can ca ll up the fo llowi ng i nformation in
the on -boar d computer:
- Dat e
- Dr iv ing t ime (h) fro m the short-term memo-
ry
- Average consumption in MPG ( l/100 km)
from the short-te rm memory
- Average speed i n mph (km/h) from the
short-te rm memory
- Distance driven in miles (km) from the
short-term memory
- Current fuel consumption in MPG ( l/100
km)
- Short-term memory overview
- Long-te rm memory ove rview
T he short-te rm memory collec ts dr iv ing in for­

select the time period for evaluat ing trip in­
formation yourself.
F or some veh icle functions, you can access the
t r ip information from the temporary memory
in the
line @~page23, fig. 5.
The current fuel consumpt ion can be dis­
p la yed using a bar ~
page 26, fig. 10. The
average consumption (mpg) stored in the
short-term memory is also displayed. Electri­
cal energy can be stored in the battery when
the vehicle is coast ing or driving downhill (re­
cuperation) . The bar will move toward D.
Efficiency program*
The eff ic iency program can help you to use
l ess fuel.
It evaluates driving information in
reference to fue l consumption and shows oth ­
er equipment influencing consumption as well
as shift recommendations.
q page 25. Fuel
economy messages
q page 25 provide tips
for efficient driving. The effic iency program
uses distance and consumption data from tr ip
computer
1.
To display the efficiency program, call up Ve­
hicle functions and select the menu option
Efficiency prog ram . If the data are deleted in
the efficiency program, those values are also
reset in trip computer.
(D Tips
- All stored values w ill be lost if the veh i­
cle battery is disconnected.
- Fuel consumptions (average and cur­ rent), range and speed are displayed in
metric units on Canadian models.

ment appears in the display .
Other equipment that is currently affecting
fuel consumption is listed in the efficiency program . The display shows up to three other
items of equipment @. The equ ipment using
the most fuel is listed first. If more than three
items using fuel are switched on, the equip­
ment that is currently using the most fuel is
displayed .
A scale ® also shows the current total con­
sump tion of all other equipment.
Fuel economy messages
App lies to vehicles: with efficiency program
Fig. 9 Disp lay : example o f a fu el econo my m essa ge
Fuel economy messages are displayed when
fuel consumption is increased by certain con­
ditions. If you follow these fuel economy mes­
sages, you can reduce your vehicle's consump­
tion of fuel. The messages appear automati-
cally and are only displayed in the efficiency

and other important vehicle compo­
nents .
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
,.. Try to avo id driving short distances with a
cold engine.
The engine and catalyt ic converter have to
r each their optimal
operating temperature to
reduce fuel cons umption and noxious emis­
sions effect ively .
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 mi les (4 km),
the engine is at its proper operating tempera­
ture and fuel economy has reached a norma l
level. So you can see that you should avoid
short tr ips whenever possible.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer.
