On-board computer
You can ca ll up the followin g in formation in
the on -board computer:
- Date
- Dr iving t ime (h) from the shor t-te rm 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-te rm memory
- Cur ren t fue l consumption in MPG ( l/100
km)
- Short-term memory overview
- Long-term memory overview
T he short-te rm memory collects driv ing infor­
mation from the time the ign ition is switc hed
on until it is switched off. If you continue driv­
ing within two ho urs after switch ing the ig ni­
tion off, the new values are included when cal­
cu lating the c urrent trip information .
Un like the short -term memory, the long-term
memory is not erased automatically. You can
select the time period for evaluating t rip in­
format ion yourse lf .

26 Instruments and warning/indicator lights
For some vehicle functions, you can access the
trip information from the t emporary memory
in the line
(D ~ page 24, fig. 5.
The current fuel consumpt ion can be dis­
p layed using a bar~
page 2 7, fig. 10. The
average consumption (mpg) stored in the
short-term memory is also d isplayed. Electri ­
cal energy can be stored in the battery when
t he vehicle is coasting or driving downhill (re­
cupe rat ion) . The bar will move toward D.
Efficiency program*
The efficiency program can help you to use
less fuel. It evaluates driving information in
reference to fuel consumption and shows oth­
er equipment influencing consumption as well
as shift recommendations .
c:> page 26. Fuel
economy messages ~
page 26 provide tips
for eff icient driving . The eff ic iency program
uses distance and consumption data from trip
compute r
1.
To display the efficiency program, call up Ve­
hicle functions and select the menu option
Efficiency program .
If the data are deleted in
the efficiency program, those values are also
reset in trip computer.
@ Tips
-All stored va lues w ill be lost if the veh i­
cle battery is disconnected .
- Fuel consumptions (ave rage and cur­
r ent), range and speed are displayed in
metric units on Canadian models.
Other equipment
Applies to vehicles: with efficiency program

Requirement: The efficiency program must be
displayed

,. Tur n the thumbwheel unti l the other equip-
ment appears in the display.
Other equipment th at is currently affecting
fuel consumpt ion is listed in the effic iency
program. The display shows up to three other
items of equipment @. T he equipment 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 tota l con­
sumption of all other equipment.
Fuel economy messages
Applies to vehicles: with efficiency program
Fig. 9 Display : example of a fuel econo my m essage
Fuel economy messages are displayed when
f uel consumption is increased by certa in con­
ditions. If you follow these fue l 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
program. The fuel economy messages turn
off
automatically after a certain per iod of time .
.,. To turn an economy message
off immediate­
ly after it appears, press any button on the
multifunction steering wheel.
(D Tips
- Once you have turned a fuel economy message
off , it will only appear again af-
ter you turn the ign ition on again . .,,.

You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly
assess o il consumption.
This also applies to fuel consumption and en­
gine output.
(D Note
- Have yo ur vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the funct ion of the
emission control system and could lead
to damage .
- Do not alter or remove any component of
the Em ission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any dev ice, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emission Control System
and other important veh icle 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
reach their optimal
operating temperature to
reduce fuel consumption 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). Afte r abo ut
2.5 m iles (4 km),
the eng ine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips whenever possible.
Driving and environment 211
The outside temperature is also critical in this
regard . Your car consumes more fue l in the
winter than in the summer.
