Driver information system
Trip computer
Introduction
The trip computer gives you information on cur­
rent and average fuel mileage , average speed ,
fuel range and driving time .

The fo llow ing information is contin uously evalu­
ated by the trip computer and can be d isplayed
sequent ia lly in the instrument cluster display:
Fuel range
The estima ted c ruising range i n miles (km) ap­
pea rs in the disp lay . This te lls you how fa r your
ve hicle w ill be able to trave l on t he current ta nk
of fuel and with the same driv ing style. The d is­
p lay changes in increments of 5 miles (10 km) .
The cruising range is calcu lated based on t he f ue l
consumption for the last 18 m iles (30 km). If yo u
drive conse rvative ly, the cruising range will in­
crease.
Average fuel mileage
The average fuel e co nomy in MPG (l/ 100 k m)
since yo u last cleared the memory appears in this
d is pl ay. You can use this display to ad just your
driving technique to achieve a desired mileage.
Current fuel mileage
The inst antaneo us f ue l cons umption in miles per
ga llon (l/100 km) is shown in this display. Yo u
can use t his disp lay to adjust your driving techni­
que to achieve a des ired mileage .
F ue l cons umption is rec alcul ated at intervals of
33 y ards (30 me ters). Th is disp lay swit ches to
ga llons/hou r (li ters/hour) when the vehicle is not
mov ing.

rese t the memory appears in the display .
Elapsed time
The length of time that yo u have been d riving
s ince you last reset the memory appears in this
display .
Distance
The distance that has been covered since the last
time the memory was cleared appears i n the dis­
play .

range and speed a re displayed in me tric
units on Canad ian mode ls .
- All stored val ues will be lost if the vehicle

Memories
The trip computer is equipped with two fully au ­
tomatic memories.

Driving and th e environment
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rai lroad
crossings, or at traff ic lights that have long waits
on red. Turning the eng ine off for just 30-40 sec­
onds saves more fuel than is burned starting the
engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and nox ious em issions are especially h igh when
the engine is warm ing up. So you should dr ive
away as soon as you start the engine and avoid running at high rpms while the engine is still
warming up.
{[) Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended id ling a lso produces
heat, wh ich co uld resu lt in overheating or ot h­
er damage to the vehicle or other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
~ Have you r vehicle se rv iced at regular i nte rva ls.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
r u ns p roperly and economically. The condition of
your veh icle not only affe cts its safety and ability
to hold its va lue, i t also affects
fue l con sump ­
tion.
Ch eck your oil each tim e you fill your tank .
The amount of oil used is related to engine load
and speed .
It is normal for the oil consumption of a new en­
g ine to reach its lowest value after a certain mile­
age has been driven.
You must drive yo ur vehicle about 3,000 miles
(5,000 ki lometers) before you can properly as­
sess o il consumption .
This a lso applies to fuel consumption and engine
output .

(D Note
-Have your veh icle ma intained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control 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 shields, sw itches, ignit ion wires,
valves, which a re des igned to p rotect your
vehicle's Emission Control System and other
impo rtant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Tr y to avoid dr iv ing sho rt distances w ith a co ld
eng ine .
The eng ine and cata lytic converter have to reach
their opt imal
op erat ing temperature to reduce
fuel consumpt io n and noxious em issions effec­
tive ly.
Just after starting, a co ld eng ine in a mid -s ize car
o nly achieves a fuel economy of 6-8 m iles per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy climbs to 12 mpg ( 20 l/100
k m). After about
2.5 mi les ( 4 km) , the eng ine is
at i ts p roper operating tempera ture and fuel
economy has reached a normal level. So you can
see that yo u should avo id short trips whenever
poss ib le.
The
outside temperature is also cr itical in th is re­
gard. Your car cons umes more fuel in the winter
than in the summer.
