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 fo llowing 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
5 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
The 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 as well as an efficiency
program* .

You can switch between the trip computer 1
and 2 and the efficiency program* by pressing
the

You can tell which memory leve l is currently
active by the number o r the sign in the display

Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il
road crossings, or at traff ic lights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af
ter starting . If warning lights shou ld come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fu el
con sumpt ion .
Check you r oil ea ch time you fill you r tank.
The amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec
ommendations in your Wa rranty
& Main
t enance boo klet . Lack of p roper ma inte
nance as well as improper use of the ve
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap
proved by the manufacturer.
-Do not alter or remove any device, such
as heat sh ie lds, switches, ignit ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid dr iv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal
operat ing temperature to
reduce fuel consumpt ion and nox ious emis
s ions effectively .
Just after starting, a co ld eng ine in a mid-s ize
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>
