App lies to vehicles: with a ll-wheel drive
With all-wheel drive, all four wheels are driv­
en.
Gene ral inform ati on
With all-wheel drive, power is distributed to
all four wheels. This happens automatically
depending on your dr iving sty le and the road
conditions at the t ime. See a lso
r=;, page 142.
The all-wheel drive concept is designed for
h igh engine power. Your vehicle is exception­
ally powerful and has excellent dr iving charac­
ter istics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions
c::;, ,&. .
Winter t ire s
When drivi ng in the w inter, your ve hicle w ith
all-wheel drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter t ires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll f our
w heel s.
See also c::;, page 196, Winter tires.
Snow chains
Where t ire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
w ith a ll-wheel d rive

chains .
Replacing wheels /tire s
Vehicles w ith all-wheel drive must always
have tires of the same size. Also avoid t i res
with d iffe ren t tread depths. For details see
page
c::;, page 192 , New tires and replacing
tires and wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle.
It is
Int ellig ent technolog y 147
therefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
r=;, page 151.
_& WARNING
Always adjust your dr iv ing to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire tract ion. You
should t herefore not d rive at excessive
speeds on icy or slippe ry road s urfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning) . If th is should occur, yo u
wi ll have no warning from a s udden in ­
crease in engine speed as with a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions. -risk of crash.
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 conventiona l energy system
is not d rive n for a long per iod of t ime, the bat­
te ry is discharged by idling current consumers
(e.g . immobilizer). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine.
Intellige nt energy managemen t in your vehi­
cle handles the dis tribution o f electrica l ene r­
gy. Starting ability is marked ly improved and
the life of the battery is extended .

148 Intelligent technology
Battery diagnosi s
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
I dling current management reduces energy
consumption while the vehicle is standing.
With the ignition switched off, it controls the
energy supply to the various electrical compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
al components. It regulates consumption, so
that more electrical energy is not being used
than 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
limited .
- If starting ability is threatened, you are informed by a warning
~page 149,
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
driving, in city traffic and during the cold time
of year. Abundant electrical energy is re­
quired, but only a little is generated.
It is also
critical if the engine is not running and electri- cal components are turned on.
In this in­
stance energy is being consumed but none is
being generated.
It is in precisely these situations that you will
notice energy management actively regulat­
ing the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks , electrical compo­
nents are gradually cut back or switched off .
This reduces energy consumption and main­
tains starting capability over a longer period.
Take into consideration that when you unlock
your vehicle, some convenience functions ,
such as the remote key or power seat adjust ­
ment, may not be available. The convenience
functions will be available again when you
turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off, the battery is being dis­
charged.
If starting capability is jeopardized due to en­
ergy consumption, a message appears in the
driver information display.
You have to start the engine to charge the
battery.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­
brium, consumers which require especially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular require a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched .,.

off. These systems will be avai lable again as
soon as the energy ba lance has bee n restored.
You will also notice that engine idle speed has
been increased s lightly. This is normal and not
a cause for concern. By increasing engine idle
speed the additiona l energy required is gener­
ated and the battery is charged .
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can lim it the ab ility of the engine to start, th is
i s shown in the inst rument cluster display
with the following driver message:
(•) Low battery charge : battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be l imited. As
soon as you start driving aga in, the battery
w ill be recharged and the notification will go
out.
Driver notification appears and goes out
again
If th is 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
n ition is turned on or while driving and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ability is
restr icted. Have the battery checked as soon
as possible by an author ized Audi dealer or
qualified workshop.

The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometres ):
.,. Do not use full throttle .
... Do not d rive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM.
.,. Avoid high engine s peeds.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometres):
"" Speeds can gradually be increased to the
max imum pe rm iss ib le road or eng ine speed.
During and after break-in period
.,. Do not rev the engine up to high speeds
when it is cold. This app lies whether the
t ransm ission is in N (Neutral) or in gear.
After the break- in period
... Do not exceed max imum engine speed un­
der any circumstances .
.,. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
¢page 10.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving pa rts have been broken
in. How w ell this break-in p rocess is done de­
pends to a conside rable ex ten t on the way t he
vehi cle is dr iven d uring the first 1,000 miles
(1, 500 kilome tres) .
(D Note
Extremely high engi ne speeds a re auto­
mat ic all y reduced. However, t hese RPM-

limi ts were programme d for an eng ine
well run-in, not a new eng ine.
~ For the sake of the env ironment
Do no t drive with unnecessar ily high en­
gine speeds -upshifting early saves f uel,

ment.
New tires
If your vehicle is runni ng on new tires, drive
part icularly careful for the first 350 miles
(500 k ilometres) after fitting .
A WARNING
-New tires tend to be s lippery and mus t al-
so be "b roken-in". Be s ure to re m embe r
this dur ing t he fir st 35 0 m iles (500 kilo ­
me tres) . Brake gent ly . Avo id following
closely be hind ot her vehicles or other sit­
uations that m ight require sudde n, hard
b raking.
New brake pads
Remember that new brake pads do not have a
full brak ing effect during the first 250 m iles
(400 ki lometres) after they are installed .
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ &.
D uring the break-in pe riod, yo u should avoid
putting seve re loads on the brakes . Severe
l oads include, for example, su dden hard brak­
ing, in particular at very high speeds or, for
example, o n mountai n passes .
A WARNING ~
Until they develo p the maximum "bite" fo r
b est stopp ing power, the surfaces on new
b rake pads requ ire some "brea king-in" du r­
in g the initia l 10 0 to 15 0 mi les (150 to
200 kilome tres) of norm al cit y dr iv ing. Yo u
can compensate for this by pressing the
br ake pe da l mo re f irm ly . This applies
whenever new pa ds are installed.

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 dam­
aged.
T his is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any higher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv ­
ing through it.
- Do not s top the veh icle, 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.
- Avoid driving thro ugh sa lt water because
it can cause corrosion.

Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.,. Always use lead-free gasoline¢ page 161 ,
Fuel supply.
.,. Never run the tank down all the way to emp­
ty.
.,. Never put too much motor o il in your engine
c:::> page 170, Adding engine oil 9::71 .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
the vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be­
f ore they are re leased into the atmosphere .
T he exclusive use of unleaded fuel is critically
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine .
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other materia l wh ich can
cause a fire .
- Do not apply additional undercoating or
rustproof ing on or near 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 .
(I) Note
-Be aware that just one tank filling with
leaded fuel w ill already ser iously de­
grade the performance of the catalytic
converte r.
- Do not exceed the correct eng ine oil level
c:::> page 170.
- Do not drive until the fue l tank becomes
completely empty . The engine could m is-
fire. Unburned fuel could also get into

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­ hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherw ise fuel
can reach the cata lytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma intained properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper main tenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
E ven when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfur -like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w it h lead-free super
grade gasoline.
Shutting down vehicle
If you wou ld like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized dealer . T hey ca n ad­
vise you on necessary precautions e.g . corro­
sion prevent ion, ma intenance and storage.
Pay atten tion to add it iona l information con­
cerning the batte ry . Re fer to ~

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 1O-lS percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consumption on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac­
celerating.
Avoid unnecessary acce lerating and braking .
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic 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.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
""Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs whi le the engine
is sti ll warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over-
Driving and environment 153
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
Audi dealer helps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your 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 function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

154 Driving and environment
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold eng ine.
The engine and catalyt ic converte r have to
reac h their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effect ively .
- Just after starting, a co ld engine in a m id­
s iz e car burns the fuel at a poor rate of 6-8
miles per gallon (30-40 l/l00km). Half a
mile dow n the road, the m ileage imp roves
to 12 M PG (20 l/100 km) . It will take t he
engi ne no less than
two and a half mil es
(4 km) of driving to warm up to its prope r
oper ating tempe ra tur e and ope rate at an
e conomi c mileage. This explains w hy taking
t h e car for s hort tr ips is a rat her wastef ul
co nvenience.
- T he
outside temperature is also cr itica l in
t h is regard. Yo ur car consumes more fuel in
t h e winter than in t he summer .
