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 following 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 6
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
T he 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 .

- 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.

186 Driving and en vironm ent
-Be aware that just one tank fi lling with
le a ded fuel will already seriously de
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
qpage 212.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire. Unburned fuel could also get into
the exhaust system and this could cause
t h e catalyt ic converte r to overheat.
- Do not turn off the ignition while the ve
hicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherw ise fuel
can reach the catalytic converter. This
could result in overheat ing of the co n
ve rter, req uiring its repla ceme nt.
- To assure efficient operation of the Emis
s ion Control System:
- Have your veh icle maintained properly
and in accordance with the service rec
ommendations in your Warranty
&
Ma intenance booklet.
- Lack o f proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and cou ld lead to damage.
@) For the sake of the environment
Even when the Emission Control System is
operati ng properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating sta tes. This depends on
t he s ulfur content of the fue l being used .
Using a differe nt brand of fuel may help,
or filling the t ank w it h lead-free super
grade gaso line .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex
haust and noise levels.
F uel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving s tyle
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economica lly, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec
t ion w ill give you some tips on how you can
help the env ironment and your po cketbook.
@ Tips
The consumption estimates as published
by ENVIRON MENTAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre
s pon d to your actual consump tion on the
r oad, which will va ry depending upon vehi
cle load and speed, road and weather con
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac
celerating.
.,. Avoid unnecessary accelerating and brak ing.
Vehicles use the mos t fu el when they are ac
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
t h at the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
"" Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l 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 noxious emissions 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 should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which cou ld result in over-
Driving and environment 187
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
au thorized Aud i dea ler helps to ensure that it
runs properly and economic all y. The condition
of your veh icle not on ly affects its safety and
ability to hold its va lue, it a lso affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en
gine output.
(U) Note
- Have your 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 function of the
emission control system and could 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, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo
nents .

188 Driving and en vironm ent
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold eng ine.
The engine and catalyt ic converter have to
reach their optimal
operat ing tempe ratu re to
reduce fuel consumption and noxious emis
sions effect ively .
Just after starting, a cold engine in a mid-size
car only achieves a f uel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 m iles (4 km),
the eng ine is at its proper operat ing tempera
ture and fue l economy has reached a no rma l
l eve l. So you can see that you sho uld avoid
short tr ips wheneve r possib le .
The
o ut sid e temp era ture is also critical in this
r egard. Your car consumes more fuel in the
winter than in the summer.
temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il
t hat complies with A udi oi l standard
VW 502 00 . Your Limited New Vehicle War
ranty does not cover damage or malfunctions
due to fa ilure to fo llow recommended mainte
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re
pa ir Orde rs that all s chedu led maintenance
was pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of internal engine components, a ll in
ternal combustion eng ines consume a certa in
amo unt of o il. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in period (see
¢
page 184) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the ambient
temperature and road condit ions. Furthe r fac
tors are the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida
tion level of the oil. As any engine is s ubje ct to
Checkin g and fillin g 211
wear as mi leage builds up, the oil consump
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev
el, see
Note .
If the yellow engine oil leve l warning symbo l
1\1 in the instrument cluster lights up , you
shou ld check the oil leve l as soon as possib le
¢
page 212. Top off the oil at your earliest
convenience

A WARNING
Before you check anythi ng i n the engine
compartment, always read a nd heed all

in Working in the engine
c ompartment on page 207.
(D Note
Driving w ith an insufficient o il level is like
ly to cause severe damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indi cator of the oil le vel. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals, pref
erably ea ch time you r efuel, and alway s
before going on a long trip .
-If you have the impression you r engi ne
c ons umes ex cess ive amoun ts of o il, we
recommend that you consul t an a uthor
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in mind that the accurate measurement of
oil consumption requ ires great care and
may take some t ime. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.
