Other road users must not be put at risk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or ho ld the pedal down
too long or too often . This cou ld cause
the brakes to get hot and d iminish brak­
ing efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Thi s may cause the b rakes to
overheat, premature wea r and inc reased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effectiveness of the
brakes can be reduced . In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Cautiously apply brakes
for a test . Brakes will dry and ice coat­
ings w ill be cleaned off after a few cau ­
t ious brake applications .
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you
ins tall a different spoiler, be su re the air
flow to the front brakes is not obstruct ­
ed. Otherwise the brake system co uld
overheat red ucing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
braking capab ility, resulting in increased
stopp ing distance. Avoid driv ing the vehi­
cle and have it towed to the nearest au­
thorized Aud i dealer or qualified work­
shop .
- Never let the vehicle roll to a stop w ith
the engine shut off .
- If the brake booster is not working, for
example when tow ing your vehicle, or
because the b rake booste r has somehow
been damaged, the brake pedal must be pressed considerably harder to make up
for the lack of booster assistance .
Power steering
When the engine is running, power steering
makes i t easier for the driver to s teer .
Power steering helps the driv er steer the vehi­
cle with litt le physica l effort.
If the engine is not running, the power steer­
ing system is also not working . In this case ,
you wi ll find it extremely d ifficu lt to turn the
steering wheel.
If you turn the steering fully to the left or
rig ht when the vehicle is stationary, you p lace
a very heavy load on the power steering sys­
tem. Turning the steering wheel fully to the left or right will cause noise in the system. It
also reduces engine id le speed.
(D Note
Do not hold the steering t urned fu lly to
the left or r ight for more than 10 seconds
when the engine is running . There is a r isk
of damage to the power steering system .
(D Tips
-In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be ab le
to steer the vehicle. However, you will re­
quire more effort to do so .
- If the powe r stee ring system has a leak
or is defect ive , you should immediately
contact a qualified wor kshop .
- The power steer ing system req uires a
special hydraulic fl uid. The power steer­
ing fluid reservoir is located in t he en­
gine comp artment. The co rrect hydrauli c
fluid level is important for proper opera­
tion of the power steering system. The
power steering fluid level is checked ac­
cording to the Audi maintenance service
schedule.

Driving with your
quattro ®
With all-wheel drive, all four wheels are driv­
en .
Gene ral inform ation
W ith all-wheel dr ive, power is distributed to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the t ime . See also <::;>
page 142.
Winter t ires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll f our
wheel s.
Snow chain s
Where snow chains are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive
Qpage 198, Snow
chains.
Replacing wheel s/tire s
Only the wheel/tire sizes specified by the
manufacturer may be used on vehicles with
all-wheel drive
<=> page 193 .
A WARNING
-Always adjust your driving to road and
traffic conditions. Do not let the extra
safety affo rded by a ll-wheel d rive tempt
you into taking extra risks .
- Although a ll-wheel drive is ve ry effect ive,
always remember that braking capacity
is limited by tire traction . You should
therefore not drive at excessive speeds
on icy or slippery road surfaces.
- On wet road surfaces, be careful not to drive too fast because the front wheels
cou ld begin to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in­ crease in engine speed as with a front-

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventional energy system
is not driven for a long per iod of t ime, the bat­
te ry is d ischarged by idling current consumers
(e .g. immobi lizer). In certain circumstances it
can resu lt in the re being insufficient energy
available to start the engine.
Intelligent energy management in your vehi­
cle handles the distribution of e lectr ica l ene r­
gy. Starting ability is markedly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
b atte ry diag nosis, idling current m an age­
m ent
and dy namic energ y manag ement .
Batte ry diagno sis
Battery diagnosis continuously determines
the state of the batte ry. Sensors determine
battery voltage, battery current and batte ry
temperature . This determines the current
state of charge and the power of the battery.
Idling current manag ement
Idling current management reduces energy
consumption while the vehicle is standing.
Wi th the ign ition switched off, it controls the
energy supply to the various electrica l compo ­
nents. Data from battery diagnosis is consid­
ered.
Depend ing on the ba ttery's state of charge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability. .,..

Dynamic energy management
While th e veh icle is be ing dr iven , dynamic en­
e rgy management distributes the energy gen­
erated according to the needs of the individu­
a l components . It reg ulates cons umption, so
that more electrical energy is not being used
t han is being generated and ensures an opti­
mal state of charge for the battery .
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are li mited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
<=> page 148,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
d riving, in city traffic and duri ng the co ld time
of year. Abu ndant e lectr ica l energy is re­
qu ired, but only a little is g ene rated . It is also
cr itica l if t he engine is not run ning and ele ct ri­
cal componen ts ar e turned on. In th is in ­
stance energy is being consumed but none is
being generate d.
It is in precisely these si tua tions that you w ill
notice energy management actively regula t­
ing the distrib ution o f energy .
Vehicle stands for an extended period
If you do not drive you r vehicle over a period
of severa l days or weeks, elect rical compo­
n ents are grad ually cu t back o r swi tched off .
This redu ce s energy cons umption and mai n­
tains s ta rting cap abili ty over a longer period .
T a ke into considerat ion tha t when you u nlock
your ve hicle, some co nvenience func tions,
such as the remote key or power sea t adj ust ­
men t, may not be available. The convenience
f u nctions will be avai lable again when you
turn on th e ignition and start the engine. With the engine turned off
If you
listen to the radio, for examp le, w it h
t h e engine t urned off, the battery is being dis­
c h arged .
If starti ng capab il ity is jeopard ized d ue to en­
ergy consu mptio n, a mess age a ppea rs in the
drive r informa tion d isplay .
You have to start t he engine to charge the
ba tte ry.
With the engine running
Althoug h electrical energy is generated when
the vehicle is being d riven, the battery can be ­
come discharged. This happens mostly when
li ttle energy is being ge ne rated and a g reat
deal consumed a nd t he battery's state of
c h arge is not opt imal.
To b ring the energy bala nce back into equ ili­
br iu m , consume rs wh ich req uire espe cially
l ar ge amounts of ene rgy a re temporar ily cu t
ba ck or sw itched o ff. H ea ting systems in par ­
t icu lar require a grea t deal of energy . If you
not ice, for examp le, that the heated seatsat or
the heated rear window are not heating, they have been temporarily cut back or switched
off . These systems w ill be available again as
soon as the e ne rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for concern. By increasing engine id le
speed the additional energy required is gener ­
ated and the battery is charged .
Driver notification in the instrument
cluster display
If bat tery power drops in to the range where i t
can limit the ability of the engi ne to start, this
is shown in the instrument cluster display
with the following driver message:
(•] Low battery charge: battery will be
charged while driving
T h is not ifi cat io n r eminds yo u that t he start ing
ca pabili ty of the engi ne may be lim ite d. As
soon as you s tart dr iv ing again, the battery .,..

will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig­
nition is turned on or while driving and it goes
out again after a wh ile, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notification appears after the ig­
nition is turned on or while driv ing and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ability is
restricted. Have the battery checked as soon
as poss ible by an author ized Audi dealer or
qualified workshop.
Dry sump lubrication
H igh lateral and long itud inal forces affect the
engine and the vehicle during sporty driving.
Dr y sump l ubr ica tion ensures that your engine
i s supplied w ith oil and properly lub ricated
even under these conditions.
I n a "normal" veh icle the oi l pump sends the
oil from the oil pan to the lubrication points in
the engine. The oil then returns to the oil pan .
I n extreme situations, the oil pump may draw
in air, which results in insufficient oil pressure.
With dry sump lubrication, the oil is not in the
oil pan (it is "d ry"), but in a separate oi l tank.
While one pump supplies the engine with oi l,
a second pump suctions the oi l out of the en­
g ine and returns it to the oil tank . Because the
oil tank is ta ll and narrow, o il pressure is con­
stant even under extreme conditions.
In addition, the oil pan in vehicles with dry
sump lubrication is noticeably sha llower. Th is
allows the engine to be installed lower in the
vehicle, bringing down the center of gravity .
This improves your vehicle's handling .

150 Driving and en vironm ent
Driving and
environment
Break-in period
A new vehicle must be broken in, and the break-in per iod should be 1,500 miles (2,500
km) . Do not use full acceleration for the first
600 miles (1,000 km) and do not exceed the
maximum eng ine speed of 6,000 rpm You
m ust also not use fu ll acce lerat ion between
600 and 1,200 m iles ( 1,000 to 2,000 km).
Fr om 1,200 to 1 ,500 mi les (2,000 to 2,500
km), you can gradua lly increase maxim um en­
gine speed to 8,250 rpm for brief periods.
During the first ho urs of operation, there is
g reater friction in the engine and the trans­
mission than later when a ll the moving parts
have broken in.
The way yo u drive duri ng the first 1 ,500 miles
(2,500 km) affects engine quality. If you drive
at moderate engine speeds thereafter, partic ­
u lar ly when the engine is cold, yo u reduce en ­
gine wear and increase the potential mileage
of the engine.
Do not drive at RPMs that are too low. Shift
down when the engine is no longer running
"smoothly". Extreme ly high RPMs are gov­
erned automa tically.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iving t hrough water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body .
- Do not drive faster than wa lking speed .
.&_ WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet b rake roto rs and pads. Dry
t he brakes fi rst by bra king carefully to re­
sto re the full braking effect .
-
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrical sys­
tem can be severe ly damaged by dr iv ing
through water .
@ Tips
-Check the depth of the water before d riv­
ing through it.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely .
- Avo id driving through salt water because
it can cause corros ion.
Catalytic converter
You must use lead-free gasoline in your veh i­
cle, otherwise you will destroy the ca talyt ic
converter .
Never run the fuel tank completely dry; their­
regular fue l supply could cause misfires . This
allows unburned fue l into the exhaus t system,
poss ibly resulting in overheating and damage
to the catalytic converter .
.&_ WARNING ,-
-Do not park or operate the vehicle in
a reas where the hot exha ust system may
come in co nta ct with dry g rass, brush,
fue l spills or o ther material which can
cause a fire.
- Do not app ly addition al under coating or
r u stproofing on or nea r the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
To ensure efficient o peration of the Emis­
s ion Control System :

-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.

use and are not an indication of material
deterioration.
(U;) Note
- Never use chemical solvents (e.g. lighter
fluid , turpentine), waxes, shoe polish or
similar products on Alcantara ® surfaces.
- To avoid damage, have stubborn stains
removed by a commercial cleaning spe­
cialist.
- Do not use brushes, stiff sponges or sim­ ilarly abrasive cleaning aids.
Safety belts
Heavily soiled safety belts may not retract
properly.
• Keep belts clean.
• For cleaning, use a mild soap and water sol­
ution. Let belts dry thoroughly and away
from direct sunlight.
• Do not allow inertia reel safety bel ts to re­
tract before they are completely dry.
• Check the condition of your safety belts
reg ­
ularly .
_& WARNING
Damaged safety belts can break in a crash.
- Anything that might damage your safety
belts could mean that you and your pas­
sengers would not be adequately pro­
tected in an accident.
- Safety belt performance depends on cor­
rect installation. Never remove belts
from the vehicle to clean them.
- Do not use chemical cleaning agents,
bleach or dyes. They have corrosive prop­
erties which weaken the webbing.
- When cleaning your safety belts, inspect
them for damage. If you discover dam­
age, see your authorized Audi dealer.
- Always read and heed all WARNINGS and
the information
¢page 153.
1) Use o nly the co rrect cle anin g so lu ti on s. Never use gas­
o lin e or die se l fuel.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Corrosion protection
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti-corrosion treatment is very impor­
tant, particularly in the winter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent salt damage .
At the same time, the underside of the vehicle should be washed as well.
If the engine compartment is cleaned at any
time with grease removing solutions
1> , or if
you have the engine washed, the anti-corro­ sion treatment is almost always removed as
well.
It is therefore essential to have a long­
lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment.
A WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before working in the engine compart­
ment, be sure to read the information
¢page 169.
-Before reaching into the front plenum
panel, always remove the ignition key .
Otherwise, the windshield wiper system
could unintentionally be switched on,
possibly causing personal injury from the
moving wiper linkage.
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can switch
on suddenly- even when the ignition is
off.

-Do not wash, wax or dry the engine with
the engine running. Moving or hot parts
could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts w ithout protecting your
hands and arms. You may cut yourself on
sharp-edged metal parts .
- Always read and heed all WARNINGS and
other information
