On-board computer
Fig. 8 In strume nt cluster : fuel consump tion
You can ca ll u p t he following information in
the on-board computer:
- Date
- Dr iving t ime (h) from the sho rt-term memo-
ry
- Average consumption in MPG ( l/100 km)
from the short-term memory
- Average speed i n mph (km/h) from the
short-te rm memory

-Distance d riven in mi les (km) from the
short-term memory
- Current fue l co nsumption in MPG (l/100

- Sho rt-t erm memo ry overview
- Long -term memo ry overview
The sho rt-term memo ry co llects d riving i nfo r­
mat ion from the time the ignition is switched
on un til it is switched off . If yo u con tinue dr iv­
i ng wi thin two hou rs a fter switching the igni­
tion off, the new val ues are i ncl uded when cal­
culating the current trip informa tion .
Unlike the short-term memory , the long-term
memory is no t erased au toma tically. You can
se lec t t he time period fo r eval uat ing trip in­
formation yo urself.
For some ve hicle fu nctions, you can access the

Fuel consumption
The cu rrent fuel consumpt ion can be dis­
p layed using a bar
c::> fig. 8 . The average con­
sumpt ion (mpg) stored in the short-term
memory is a lso di splayed. Whe n the bar tur ns
g reen, you r vehicle s aves fuel by one of the
followi ng fun ctions:
- Recuperation : When the vehicle is coasting
o r dr iv ing downh ill, ele ctrical energy ca n b e
store d in t he b atte ry. The bar w ill move to ­
ward 0.
-Cylinder on demand System* : when the de­
ma nd for power is low a nd other conditions
are met, the en gine automa tica lly deac ti­
vates four cylinde rs . T he driver and passen­
gers w ill not eve n notice th is . T he message
4 cylinder mode appears under the bar . T he
cylinders switch on again when more power
is needed .

The efficiency program can he lp you to use
less fue l. It shows othe r equipment influenc­
ing consumption and fuel economy messages
provide t ips for eff icient driving. The eff ic iency
program uses distance and co nsump tion data
from t rip computer 1 .

Other equipment
Other equipment that is cu rrently affecti ng
fuel consumpt io n is liste d in the view
Con­
sumer . The display shows up to three other
items of eq uipme nt @

more than th ree items us ing f uel are sw itched

A scale @also s hows the current total co n­
sumption of all othe r equipmen t.

You must drive your vehicle about 3,000 miles (5,000 ki lometers) 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
M leve l. So you can see that you should avoid N
j short trips whenever possible.

Driving and environment 207
The outside temperature is also critical in this
regard . Your car consumes more fue l in the
winter than in the summer.
