You can tell which memory level is currently active by the number in
the display => fig. 23. The data from the single -trip memory
(memory level 1 l is being displayed if a

Driver inf orma tion d ispl ay
S in gle- trip m em ory (Tr ip co mputer 1)
The single -trip memory stores the trip informa tion from the time the
ignition is turned on until it is turned off. If the trip is continued
w ithin 2 hour s from the time the ignition was turned off, the new
data will be included in the calculation of the current trip informa­
tion. If the trip is interrupted for
mo re t han 2 ho ur s the memory is
reset automatically.
T ot al-tr ip m emor y (Trip comp uter 2)
Un like the s ingle-trip memory, the total -trip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manua l resets .
Fuel r an ge
The es timated cruising range in miles (km) appears in the display .
This tells you how far your vehicle wil l be able to trave l on the
current tank of fuel and with the same driving style. The display
changes in increments of 6 miles (10 km).
The cruising range is ca lculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase.
Ave rage f uel m ileage
The average fuel economy in MPG (1/100 km) s ince 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.
Curren t fue l mile age
The instantaneous fuel consumption in mi les per ga llon (1/100 km)
is shown in this display. You can use this disp lay to adjust your
driving technique to achieve a desired mileage.
Fuel consumption is recalcu lated at intervals of 33 yards (30
meters). When the vehic le is stationary, the most recent fuel
consumption is displayed.
A ve ra ge speed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
Elapsed time
The length of time that you have been driving since you last reset
the memory appears in this display .

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the function of the emission control system
and could lead to damage.
'£> For the sake of the environm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas sme ll under some
operating states. This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoilers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low -slung chassis (sports
chassis)* and fully loaded vehicles.

General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitat ions

If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumpt ion by 10 -15 percent . This

[ i ] Tips
The consumption est imates as published by ENV IRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which will vary
depending upon vehicle load and speed, road and weather condi­

Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating .
-Avoid unnecessary accelerating and brak ing.
Vehicles use the most fue l when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic 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.
Acce lerating gently reduces fuel consumption, engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximately
three quarters of top speed, fuel consumption wil l be reduced by •

The engine oil used in your Audi needs the right kind of
oil.
The engi ne in y our Audi is a sophisticated powe rp lan t tha t was built
to exacting specifications. This engine needs the right kind of
eng ine oil that meets specifications regarding quality and viscos ity
so that it can run smoothly and reliably . Choosing the right oil and
changing oil within the time and mileage interva ls printed in your
vehic le's Warranty
& Maintenance booklet matters a lot more today
than it did years ago. Audi has developed a special quality standa rd
f or e ngin e oil tha t w ill help assure that your vehicle's engine will get
the lubrication it needs for proper operation.
Modern engine lubrication has taken a quantum leap i n the last few
years. Many synthetic oils ava ilable today provide better engine
lubrication that can o utlast traditional petro leum -based oil s,
making them a smart choice for use throughout the life of your Audi.
Whether you use synthetic or petro leum -based engine oil, the oi l
tha t you use mus t conform to Audi 's oi l qual ity standard VW 502 00
to help keep your vehicle's engine running smoothly and help ._

Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components , all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break -in period (see~
page 219) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the oil. As
any engine is subject to wear as mileage builds up , the oil consump­
tion may increase over time until replacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster lights up, you should check the oil level as soon as
possible
with the oil dipstick~ page 254. Top off the oil at your
earliest convenience~
page 255.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
~ & in "Working in the engine
compartment" on
page 250.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i] Tips
• The oil pressure warning display 't!::r. is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the accurate measurement of oil consumption requires great
care and may take some time . Your Audi dealer has instructions
about how to measure oil consumption accurately. •
