Instrument s and warning /indicator lights 25
- Long-term memory overview
The short-term memo ry co llects driving infor­
mat ion from the time the ignition is switched
on un til it is switched off. If you continue dr iv­
ing within two hours after switching the igni­
tion off, the new values are included when cal­
culating the current trip information.
Unlike the short-te rm memory, the long-term
memory is not erased automatically. You can
select the time period for evaluating trip in­
formation yourself.
F or some veh icle functions, you can access the
trip information from the temporary memory
in the line
(D r=;, page 23, fig. 5.
The cu rrent fuel consumpt ion can be dis­
p layed using a bar
r=;, page 26, fig. 10. The
average consumption (mpg) stored in the
short-term memory is also displayed. Electri­
cal energy can be stored in the battery when
the vehicle is coasting or driving downhill (re­
cuperation) . The bar will move toward
t:3 .
Efficiency prog ram
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.
r=;, page 25. Fuel
economy messages
r=;, page 25 provide tips
for efficient driving . The effic iency program
uses distance and consumption data from tr ip
computer
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 .
(j) Tips
-All stored va lues will be lost if the veh i­
cle battery is disconnected.
- Fuel consumptions (average and cur­
rent), range and speed are displayed in
metric units on Canadian models.
Other equipment

.,. Turn the thumbwheel unti l the other equip-
ment appears in the display .
Other equipment that is currently affecting
fuel consumption is listed in the efficiency
program. The display shows up to three other
items of equipment @. The 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 total con­
sumption of all other equipment.
Fuel economy messages
Fig. 9 Disp lay: example of a fuel econo my m essa ge
Fuel economy messages are displayed when
fuel consumption is increased by certain con­
ditions. If you follow these fuel economy mes­
sages, you can reduce your vehicle's consump­
t ion of fuel. The messages appear automat i­
cally and are only displayed in the efficiency
program . The fue l economy messages turn off
automat ical ly after a certa in period of time . .,.

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ich will vary depend ing upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
celerating . If you anticipate what is go ing to
h appen next, you will need to b rake less and,
thus, accelerate less. Let the vehicle coast
wheneve r poss ible -fo r example when you see
that the nex t tr affic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ T ry and keep well below your car's max imum
speed.
Accelerating gent ly reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fuel consumption, exhaust emissions and en­
g ine no ise increase d ispropo rtionately at high
speeds. If you dr ive at approxima tely three
q uarters of top speed, fue l consumption will
be red uced by one ha lf. Never dr ive faste r
than the posted speed limit and wea ther con­
d itions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel.
~ S hu t the engine off when you a re not dr iv ing
t h e vehi cle.
Dri vin g and en vironm ent 201
~ Do not warm up the vehicle by lett ing the
engine run at id le .
It makes sense to shut off the engine in traffi c
jams, when wa it ing fo r tra ins to pass at rail ­
road crossings, or at traffic lig hts that have
long waits on red. T urning the engine off for
just 30-40 seconds saves more fuel than is burned start ing the e ngine again.
It takes a long time for the engine to warm up
fully when it is runn ing at id le. However, wear
and noxious emissions are especia lly high
when the engine is warm ing up. So you should
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up .
(D Note
Do not leave engi ne idling unattended a f­
ter start ing . If warning lights sho uld come
on to i ndicate improper operat ion, they
would go unheeded. Extended idling a lso
p rodu ces hea t, w hich could re sul t in ove r­
hea ting or othe r dam age to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
~ Have your ve hicle serviced at reg ula r i nter-
vals.
By having your veh icle regula rly serviced by an
Audi deal er he lps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affec ts its sa fe ty and ability to
hold its value, it also affects
fuel con sump­
tion .
Check your oil each time you fill your tank.
The amou nt of oi l used is re lated to eng ine
load and speed.
It is normal fo r th e oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has bee n driven .

202 Driving and en vir onm ent
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess o il consumption.
This a lso applies to fuel consumption and en­
gine output.
0 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 Emi ssion 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 Emiss ion Control System
and othe r important veh icle compo­
nen ts.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.. Try to avo id driving short d istances with a
co ld eng ine .
The engine and ca talytic conver ter have to
reach their optimal
op erating temp eratur e to
reduce fuel consumption and noxious emis­
sions effect ively.
Jus t after s tarting, 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
ha lf a m ile, fue l 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 ope rat ing tempera­
ture and fue l economy has reached a norma l
l eve l. So you can see that you should avoid
short trips whenever possib le . T
he
ou tsid e tempe rature is also critical in this
regard . Your car consumes more fue l 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 wi th A udi oi l standard
VW 502 00 . Your Limited New Vehicle War ­
ranty does not cover damage or malfunctions
d ue to fa ilure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty
&
Maintenance book let . Your dea ler 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
wa s pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle dep ends 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 i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 198) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l 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 amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 217
wear as m ileage 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
in the instrument cluster
II li ghts up, you
sho uld check the oil leve l as soon as possib le
¢
page 218. Top off the oil at your earliest
convenience

A WARNING
Before you c heck anythi ng i n the engine
com partment, always read a nd heed all
WARNINGS¢ .&.
in Working in th e engine
c ompartment on page 213.
(D Note
D riving w ith an insufficient o il level is like­
ly to cause sever e damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator 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 refuel, and always
before going on a long trip .
-If you have the impression yo ur engi ne
c ons umes ex ce ss ive amoun ts of o il, we
recommend that you consul t your Au di
de aler to have the cause of your concern
properly diagnosed . Keep in mind that
the accurate meas urement of o il con ­
sumption requires great care and may
take some t ime. Y our Audi dea ler has in­
struct ions about how to measure oil con­
sumption accurately.

-Turn the valv e stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjus ted when the tires are cold . The
s li ght ly raised p ressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying .
- Re insta ll the va lve stem cap on the valve.
When should I che ck the tire pres sur e?
The correct tire pressure is espec ially impor­
tant at high speeds. The pressure should
therefo re be checked at least once a month
and a lways before start ing a journey.
When should I adjust the tire p re ssure s?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels. In addition , you must then
store the new ti re pressu res in the t ire pres ­
sure monitoring system
r::!.> page 246 .
A WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of contro l, collision, serious persona l injury
or even death.
- When the warning symbo l
[ti] appears in
the instrument cl uster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla ­
t ion can cause increased tire wear and
can affect the handling of the veh icle and
stopp ing ability .
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de ­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tir e pressures fo r all t ires on the vehicle .
T he applicable pressu re va lues are locat­
ed on a stic ker on the drive r's side B-pil­
lar .
- Only when a ll t ires on the vehicle are fi l­
led to t he cor rect pressure, the ti re p res-
Tire s an d wheel s 235
sure monitor ing system can work cor­
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system .
- Always inf late t ires to the recommended
a nd correct t ire p ress ure before dr iv ing
off.
- Driving with unde rinflated tires bend
mo re, lett ing t hem get too hot resulti ng
in tread separation, s udden tire failure
and loss of cont ro l.
- Excess ive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
a nd loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prema turely and the
veh icle w ill not handle well.
- If the tire is not fla t and you do not have
to ch ange a wheel immedia tely, drive a t
red uced speed to the nearest service sta ­
tion to check the t ire p ress ure and add
air as requi red.
(D Note
Dr iving w it h out valve stem c aps can c ause
damage to the tire valves . To prevent this,
a lways make sure that factory insta lled
va lve stem caps on all whee ls are sec urely
mounted on the valve .
@ For the sake of the env ironment
Un derinflated tires wi ll also increase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry.
A vehicle that is overloaded will not handle
well and is mo re d iff icult to stop. Overloading
can not o nly lead to loss of vehicle control,
but can also damage important parts of the
vehicle and c an le ad to sudden tire fa ilu re, .,..
