Using the climate controls economically
Economical use of the climate controls helps
to save fuel.
When climate control is wor king in cool ing
mode, engine performance is reduced and
fuel consumption is affected. To keep the time
the air conditioning is on as short as possible,
you shou ld do the fo llow ing:
.,. If you would like to save f uel, sw itch the air
condition ing 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 emissions
from the vehicle.
Rear window defogger
The rear window defogger clears the rear win­
dow of condensation .
... Press the~ button c::> page 72, fig. 82 to
turn the rear window defogger on and off.
The rear window defogger works only when
the eng ine is running. The indicator light in
the butto n illum inates 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 switch the rear window defogger
off. The reduced power consumption has a
beneficial effect on fuel consumption.
Heated seats
The seat cushion and the seotbock of the
front seats con be heated electrically.
... Press the heated seats button I- ., +I
c::> page 72, fig . 82 to set the level of heating
desired.
The range of contro ls goes from 1 to 3. The
heat setting selected is shown by LEDs above
the button.
(D Note
To avoid damage to the heating elements
in the seats, do not kneel on the seats or
place heavy loads on 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 h icle 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 ex treme 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
180.
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 159
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.
(D Tips
- Some race tracks (e.g . steeply banked
t u rns) may affect the response of the
ESP .
- 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 ironme nta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
By having your ve hicle reg ularly se rv iced by an
authorized Aud i dea ler helps to ens ure that i t
r uns properly and econom ica lly. The condition
of your veh icle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
con sumptio n.
The amount o f oi l used is re lated to engine
load and speed .
It is normal fo r the oil consump tion of a new
engine to reac h its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 mi les
(5,000 kilometers) before you can p rope rly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service

196 Tires and wheels
wheels you have to adjust the tire pressures
on all wheels.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin­ flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle .
The applicable pressure values are locat­
ed on a sticker on the driver's side 8-pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system can work cor­
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor­
ing system .
- Always inflate tires to the recommended
and correct tire pressure before driving
off .
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the tires will wear prematurely and the
vehicle will not handle well. -
If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the tire pressure and add
air as required .
(D Note
Driving without valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will 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 more difficult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire failure, in­ cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle . These
load limits are technically referred to as the
vehicle 's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs. (68 kg) for each
passenger at a designated seating position
and the total weight of any luggage in the ve-
hicle. ..,_
