Driving with your
quattro
Applies to veh icles: w ith all-w hee l d ri ve
With all-wheel drive, all four wheels are driv­
en.
General information
Wi th a ll-w heel d rive, power is dis trib ute d to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the time . See a lso
¢ page 153.
The all -whee l dr ive concept is des igned for
high eng ine power. Your veh icle is except ion ­
ally powerfu l and has excellent d riving charac­
terist ics both under normal driving conditions
and on snow and ice. Always read and follow
safety precaut ions¢ .&..
Winter tires
When driving in the winter, yo ur vehicle with
all-wheel drive has an advantage, eve n wit h
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
all four
wheel s.
See also ¢ page 210, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also app lies to ve hicles

with all-wheel drive¢ page 211, Snow
chains .
Replacing wheels /tire s
Vehicles w ith all-wheel drive mus t always
h ave tires o f the same size. Also avoid t ires
with different tread depths. For details see
page
c::> page 206, New tires and replacing
tires and wheels.
A WARNING
Always adjust your driving to road and traf­
fic condit ions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should therefore not dr ive at excess ive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
c ou ld beg in to s lide on top of the water
(aquaplaning). If this sho uld oc cur, you
will have no warning from a sudden in­ crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds which are suited 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 conventional energy system
is not driven for a long period of time , the bat­
tery is discharged by idling cu rrent consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insufficient energy

Intelligent energy management in your veh i­
cle handles the d istribution of elec trical ener­
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Intellig ent technolog y 159
Basica lly, energy management consists of
b att ery diag nosis , id lin g cur rent man age­
ment
and dyn amic en ergy m anag ement.
Batte ry diagnosis
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 batte ry .
Idlin g current manag ement
Id ling current management reduces energy
consumption while the vehicle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnosis is cons id­
ered.
Depending on the battery's state of charge ,
individual consumers are gradually turned off
to prevent excessive discharge of the batte ry
and thus maintain starting capability .
Dynamic energy manag ement
While the vehicle is being driven, dynamic en­
ergy management distributes the energy gen ­
erated according to the needs of the individ u­
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 start ing ability is threatened, the indi­
cator light (•) ;ippears

What you should know
The highest priority is given to maintaining
starting capability .
The battery is severe ly taxed in short-distance
driving , in ci ty traff ic and during the cold time

required, but on ly a little is generated. It is al­
so critical if the engine is not running and
e lectrical components are turned on. In this
instance energy is being consumed but none
is being genera ted.
It is in precisely these situations that you wi ll
notice energy management actively regulat­
ing the distrib ution of energy.
Vehicle stands fo r an e xte nded p eriod
If yo u do not drive you r vehicle over a pe riod
of severa l days or weeks, elect rical compo ­
nents are grad ually cut back or switched off.
This reduces energy consumption and main ­
tains starting capab ility over a longer period.
Some of the conven ience functions may not
operate, such as the inter ior lig hts or the
power seat adjustment . Th e conven ience
functions w ill be ava ilable again when you
switch on the igni tion and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off or use other MMI func­
tions, the ba tte ry is being d ischarged .
If starting capability is jeopardi zed due to en­
ergy consumpt ion, an error message appears
in the MMI display .
The warning message indicates that the sys ­
tem will be turned off automat ically. If you
wish to continue using the functions , you have
to start the engine .
With the engine running
Altho ugh electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged . T hi s happens most ly when
little energy is be ing generated and a great
deal consumed and the battery 's state of
cha rge is not optimal.
To br ing the energy balance back into equili­
brium, consumers which require especia lly
large amounts of energy are tem pora rily cut
back o r switched off . Heati ng sys tems in par­
ticular requ ire a g reat dea l of energy. If you
n otice, fo r example , that the heated se ats* or
the heated re ar window are not hea ting, they have been tempora
rily cut back or switched
off. These systems wi ll be available again as
soon as the energy balance has been restored .
You w ill also no tice th at engine id le speed h as
been increased slightly. This is normal and not
a cause for concern . By inc reasing engine id le
speed the additional energy required is gener ­
ated and the battery is charged.

The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometers ):
.,. Do not use full throttle.
.,. Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1 ,000 miles (1,000 to
1,500 kilometers ):
.. Speeds can gradually be increased to the
maximum perm iss ible road or eng ine speed .
During and after br eak-in period
.. Do not rev the eng ine up to h igh speeds
when it is cold. Th is applies whether the
transmission is in N (Neutral) or in gear.
Afte r the break- in peri od
.. Do not exceed max imum eng ine speed un­
der any circumstances .
.. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale
c.> 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 parts have been broken in . How well this break -in process is done de ­
pends to a considerable extent on the way the
ve hicl e is driven du ring the first 1,000 miles
(1,500 k ilome ters).
(D Note
Extremely h igh engine speeds are auto­
mat ica lly reduc ed. However , th ese rpm
lim its are programmed for a n engine well
r u n- in, not a new engine.
Driving and environment 161
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
very carefully for the first 350 miles (500 ki lo­
meters) after fitting.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing the f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llowing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
Avoid damaging the
vehicle
When you are d rivi ng on poo r roads, or over
cu rbs, steep ramps, etc., make certa in that
low- ly in g parts s uch as spo ile rs and ex ha ust
system parts do not bottom o ut and get dam ­
aged.
Th is is espec ially true for veh icles with low­
s lung chassis (spo rts chas sis)* and fully load ­
ed vehicles.
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 c'.> page 175,
Fuel supply .
.. Never r un the tank down all the way to emp­
ty.
.. Never put too much motor o il in your engine

162 Driving and en vironm ent
The cata lytic converter is an efficient "clean­
up" device built into the exhaust system of
the veh icle. The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
-The temperature of the exhaust system
is high, both when driv ing and after stop­
ping the engine.
- Never touch the exhaust tail p ipes once
they have become hot. This could result
in burns .
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
c ause a fi re.
- Do not apply additional undercoating or
rustproofing on o r near the exhaust
man ifold, exhaus t pipes, catalytic con­
verte r o r heat shie lds. D uring driving, the
substance used for undercoating cou ld
overheat and cause a fire.
(D Note
- Be aware th at just one tank fi lling with
leaded fue l will already seriously de ­
grade the performance of the catalytic
conve rter .
- Do not exceed the correc t engine oil leve l
~page 184.
-Do not drive un til the fue l tank becomes
completely empty . The engine could mis­
fire. Unburned f uel could a lso get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not turn off the ignit ion while the ve­
hicle is moving.
- Do not continue to operate yo ur vehicle
u nder these conditions , as otherw ise fuel
can reac h the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement. -
To assu re efficient operation of the Emis ­
sion Control System :
- Have your vehicle maintained properly and in accordance w ith the service rec­
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
i mproper use of t he vehicle wi ll impair
the function of the em ission cont ro l
sys tem an d could lea d to damage.
~ For the sake of the environment
Eve n when the Emiss io n Control System is
ope rat ing proper ly, the exha ust gas c an
have a sul fur- like ex haust gas smell under
some ope rat ing states . This depends on
the sulfur content of the fuel being used. Using a different brand of fue l may help,
or f illing the tank with lead-free super
grade gasoline.
Shutting down vehicle
If you would like your vehicle to remain inop­
erative for a longer per iod of time, contact an
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e .g . corro­
s ion p revention, maintenance and sto rage .
Pay attent ion to additional info rmat io n con­

Gene ral
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, e nvir onme nta l impact, and
we ar on your eng ine, b rakes and tires la rgely
depend on three fac to rs:
- your personal driving style
- operati ng conditions

If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent. This sec­
tion will give you some tips on how you can help the environmen t and your pocketbook.
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ich will vary depend ing upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessa ry accelerating and braking.
Vehicles use the most fuel when they are ac ­
celerating . If you anticipate what is go ing to
happen next, you will need to brake less and,
thus , accelerate less. Let the vehicle coas t
whenever poss ible -for example 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 be low your car's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. Fue l consumption, exhaust emissions and en­
g ine no ise increase d isproportionately at high
speeds . If you dr ive at approximately three
qua rters of top speed, fue l consumption will
be red uced by one half. Never dr ive faste r
than the posted speed limi t and wea ther con­
ditions permit.
Dri vin g and en vironm ent 163
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 lett ing the
eng ine run at idle .
It makes sense to shut off the engine in traffic
jams, when wa it ing for tra ins to pass at rail ­
road crossings, or at t raff ic lights that have
l ong waits on red . T u rning the eng ine off for
just 30-40 seconds saves mo re fuel tha n is
bur ned star ting the engine again.
It takes a long t ime for the engine to warm up
fully when it is runn ing at id le. However, wear
and noxious emissions are especia lly hig h
when the eng ine is wa rm ing up. So yo u shou ld
drive away as soon as yo u start the engine and
avoid r unning at high rpms whi le the engine is
still warming up.
(D Note
D o not leave engine idling unattended af­
ter starting. If warning lights sho uld come
on to indicate improper operation, they
would go unheeded. Extended idling also produces heat, w hich could res ult in over­
heating or other damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
.,. Have you r veh icle serviced at regu lar inter-
vals.
By having your ve hicle reg ularly serviced by an
a uthorized Audi dea le r helps to ensure that it
runs properly and econom ica lly. The cond ition
of your veh icle not only affects its safety and
ability to ho ld its va lue, it a lso affects
fuel
con sumption .
Chec k your o il each t ime you fill your tank.

The amount of oil used is related to eng ine
load and speed.
I t is normal for the oil consumption of a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You must drive your vehicle about 3 ,000 miles
(5,000 kilometers) before you can properly
assess o il cons umption .
This a lso applies to fuel consumption and en­
g ine output .
0 Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your War ranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as imp roper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not a lter or remove any component of
the Emi ssion Contro l System unless ap­
proved
by the manufacturer.
- Do not a lter or remove any device, such
as heat shields, switches, ignition wires,
va lves, which are designed to protect
your vehicle's Emiss ion Control System
and other important veh icle compo­
nents .
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
• Try to avo id driving sho rt distances with a
cold eng ine.
The engine and catalytic converter have to reach their optimal
ope rating tempe ratu re to
reduce fuel con sumption and noxious emis­
sions effect ively.
Just after starting, a cold engine in a mid-size car on ly achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km) . After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2. 5 miles (4 km), the engine is at its proper operating tempera
­
ture and fuel economy has reached a normal
l evel. So you can see that you should avo id
short trips whenever possible.
T he
out sid e tempe rature is also critical in this
regard . Your car consumes more fue l in the
winter than in the s ummer.
Driving offroad
General information
When driving off road, the functions fo r the
electron ic stabiliza tion control ( ESC) are ex­
panded . The ESC-Offroad-Mode can be activat­
ed in driving situations in which a wheel lock
or a differential lock function is needed

Aft er d riving offroad
-After driving offroad, remove branches and
other debris from the radiator gri lle, under ­
body, and wheels. Look especially for objects
(stones) that have been caught in the tire
tread.
- Clean the body and the vehicle underbody
and inspect the vehicle for possible damag­
es.
- Clean off the dirty windows, headlights, tail
lights and the license plate .
- Pe rform a brake test (especially after driving
through water).
A WARNING
- Be especially aware and attent ive when
driving under difficult condit ions . Dam­
ages to the vehicle and injur ies may oc­
cur when driv ing at an excessively high

- Please note that the wheels can spin and
the vehicle can break away when the ESC
Offroad Mode is switched off, especially
when the road is slippery.
- Driv ing stability is reduced in the ESC
Offroad mode.
@ For the sake of the envi ronment
Avoid harming the environment and take
nature into consideration .
(D Tips

stay on the provided roads and paths .
Driver messages
There is only one right way to drive in difficult
conditions: slowly and with caution!
When driv ing offroad, observe the following:
• Never dr ive the veh icle in terra in which is
not suitable for the veh icle, or wh ich ex­
ceeds your driving skills. Never take any un­
necessary risks!
• Drive slowly and cautiously!
• Pay attention to the
gro und cl earance of
your vehicle! This may vary depending on
the load and composition of the ground and
the environment. The driver is therefore re­
spons ible for deciding whether a vehicle can
handle a specific situation .
• Activate the
ESC-Offr oad-Mode Q page 155
as needed.
• Use the
hill desce nt ass is t Q page 155 when
driv ing down steep sections on hi lls.
Difficult terr ain
Never drive in areas that are not familiar to
you and dr ive slowly when offroad and be pre­
pared and expect the unexpected (e.g . pot­
holes, bou lders, tree stumps, etc.)
To prevent the vehicle from bottoming and
avoid damage to the underbody , you should
drive straight across severe bumps in the
Dri vin g and en vironm ent 165
ground with only one side o f the veh icle so
that only two of your whee ls cross the bumps.
Drive quickly through sandy or marshy offroad
sections and do not stop, if at all possible .
Driving throu gh w ater on road s
Note the following to avoid veh icle damage
when driving through water, for examp le on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than walking speed .
A WARNING
--After driving through water, mud, slush,
etc., the brakes may be slow to take effect because of wet brake rotors and pads. D ry
the bra kes first by braking carefully to re­
store the fu ll braking effect.
(D Note
Vehicle components such as the eng ine,
transmission, suspension or electrical sys­
tem can be severe ly damaged by dr iv ing
th rough water.
(D 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
thro ugh water.
- Keep i n mind that oncoming veh icles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through sa fely.
- Avo id d riving through salt wate r because
i t can cause corros ion.
