memory is not rese t autom atically. This per ­
mits you to eval uate your d riving data for the
enti re pe riod between manual resets.
Fuel range
The e stima ted cruising ra nge in miles (km)
ap pears in the display. The disp lay ch anges in
increments of 6 miles ( 10 km) .
Average fuel mileage
The average fuel economy in MPG (l/ 100 km)
si nce you last clea red the memory appears i n
this displ ay .
Current fuel mileage
The instantaneous fuel consumption in miles
pe r gallo n (l/ 100 km) is shown in this d isplay .
When the ve hicle is stationary, the most r e­
cent fuel consumpt ion is di splayed.
Average speed
The average speed in mph (km/h) si nce the
last time the disp lay was reset appears in the
d isplay .
Elapsed time
The length of time that you have been driving
since you last reset the memo ry appears in

Using the climate controls economically
Economical use of the climate controls helps
to save fuel.
When climate con trol is wor king in cool ing
mode, engine performance is red uced and
fuel consumption is affected. To keep the time
the air conditioning is on as short as possib le,
you shou ld do the fo llow ing:
.,. If you wo uld like to save f uel, sw itch the air
conditioning off .
.. If you open the windows whi le driving,
switch the air conditioning off.
.,. If the vehicle is extremely hot due to the
heat of the sun, briefly open doors and win­
dows.
@ For the sake of the environment
When you save fuel, you reduce em iss ions
from the vehicle.
Rear window defogger
The rear window defogger clears the rear win­
dow of condensation .
.. Press the Iii button <=> page 65, fig. 79 to
turn the rear window defogger on and off.
The rear window defogger wor ks only when
the eng ine is r unning. The indicator light in
the button illuminates when the rear window
defogger is turned on.
The rear window defogger is switched off au ­
tomatically after approx . 10 minutes .
@ For the sake of the environment
As soon as the rear window is clear, yo u
should switc h the rea r window de fogger
off . The reduced power consumption has a
beneficial effect on f uel consumption.

Heated seats
Applies to vehicles: with heated seats
The seat cushion and the seatback of the
front seats can be heated electrically.
.. Press the heated seats button I-J + I
<=> page 65, fig . 79 to set the leve l of heating
desired.
The range of cont ro ls goes from 1 to 3. The
heat setting selected is shown by LEDs above

A WARNING
--=
Indiv iduals wit h reduced sens itiv ity to pa in
or temperature could deve lop burns when
using the seat heat ing funct ion. To reduce
the r isk of injury, these ind ividuals should
not use seat heating.
@ Note
To avoid damage to the heat ing e lements
i n the seats, do not kneel on the seats or
place heavy loads o n a small area of the
seat.

-Have you r vehicle maintained properly
and in accordance with the service rec­
ommendat ions in your Warranty
& Main­
tenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the Emission Control Sys­
tem and could lead to damage.
Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv ­
ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or­
der to raise the engine oil temperature to a minimum of 140 °F (60 °(). The tires also on­
ly reach their full road holding capability once
they have warmed up.
The cooling fan can continue to run in your ve­ hicle after the engine is switched
off. H owev­
er, driving the vehicle to cool it down is part ic­
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become extreme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex­
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera­
tion
¢ page 17 4 .
You shou ld definitely inspect your vehicle af­
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 151
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work­
shop will be happy to undertake an inspection
before and after use on the race track.
_& WARNING
-
Some race tracks (e.g. steeply banked
turns) may affect the response of the ESC.
(D Tips
- Review the track requirements and con­
ditions before you start driving.
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re­
sult in increased wear.
Operation and maintenance
Fuel economy, env ironmenta l impact, and
wear on your eng ine, brakes and tires la rgely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
By havi ng your ve hicle reg ularly se rviced by an
a uthorized Aud i dea le r helps to ens ure that i t
runs properly and economica lly. The condition
of your vehicle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
consumption .
The amount of oi l used is re lated to engine
load and speed .
It is normal for the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before yo u can p rope rly
assess oil consumpt io n.
Th is also app lies to fue l consumption and en-
gine o utp ut.
