brake. This may cause the brakes to over­
heat, premature wear and increased stop­
ping distance.
- Under certain climatic and operating condi­
tions such as passing through wate r, driving
in heavy rain o r after washing the vehicle,
the effectiveness of the brakes can be re­ duced. In w inter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fully apply b rakes for a test. B rakes wi ll dry
and ice coatings wi ll be cleaned off after a
f ew caref ul bra ke applications .
- Dr iv ing for an extended period of time on
salt-covered roads w ithout using you r
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you in­
stall a different spoi ler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­ ing the effectiveness of the ent ire brake sys­
tem .
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driv ing the veh icle
and have it towed to the nearest authori zed
Audi dealer or qu alified workshop.
- Never let the vehicle roll to a stop w ith the
eng ine shut off.
- If the brake booster is not work ing, the
brake pedal must be pressed conside rably
harder to make up fo r the lack of booste r as­
sist ance.

Driving with your quattro
With all -wheel drive, all four wheels are driven.
General information
With a ll-wheel d rive, power is distr ibuted to a ll
fo ur wheels. This happens automati ca lly depend­
i ng on your d riving s tyle and the road condi tions
a t t he t ime . See a lso <:!>
page 191. .,.

Smart Technolog y
A center differentia l distributes the driving power
variably to the front and rear axle. It works to­
gether with selective wheel torque contro l, which
activates when driving through curves
c:::;,page 191.
The all-wheel drive concept is designed for high
engine power . Your vehicle is exceptionally pow­
erful and has excellent driving characteristics bo th under normal driv ing condit ions and on
snow and ice . Always read and follow safety pre ­
cautions
c:::;, .&. .
Wint er tires
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 advisa­
ble to mount winter tires (or all-season tires) for
improved dr iveability and braking: these tires
must be mounted on
a ll four wheels . See a lso
c:::;, page 250, Winter tires.
Tire chain s
Where tire chains are manda tory on certain
roads, this normally also applies to vehicles with
all-wheel drive c:::;, page 250, Snow chains.
Repl acing wheels /tire s
Vehicles with all-whee l drive must always have
tires of the same size. Also avoid tires with differ­
ent tread depths . For deta ils see page
c:::;, page 242, New tires or wheels .
A WARNING
Always adjust your driving to road and traffic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into ta king
extra r is ks.
- Althoug h the all-whee l dr ive is very effec­
t ive, always remember that brak ing capac ity
is limited by tire traction . You should there­
fore not drive at excessive speeds on icy or slippery road surfaces .
- On wet road su rfaces, be careful not to drive
too fast because the front wheels could be­
gin to slide on top of the water (aquaplan­
ing). If this should occur, you will have no
warning from a sudden increase in engine
speed as with a front -whee l drive vehicle.
196
Always drive at speeds which are suited to
the road cond it ions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­ bility 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 battery
i s d ischarged by idling current consumers (e .g .
i mmob ili zer). I n certain c ircumstances it can re­
s ul t in the re be ing insuffi cient energy available to
start the eng ine.
Intelligent energy management in your vehicle
hand les the d ist ribution of electrical energy.
Start ing ability is ma rkedly improved and the life
of the ba ttery is extended .
Bas ica lly, energy management consists of
bat­
t e ry diagn osi s, idling curr ent man ag ement
and
d ynami c energy management .
Batte ry diag nosi s
Battery diagnosis continuously determines the
state of the battery. Se nsors determine battery
vo ltage, battery current and battery tempera­
tu re. This determines the cu rrent state of cha rge
and the power of the battery .
Idling current management
Idling current management reduces energy con ­
sumption whi le the vehicle is standing . W it h the
i gnition switched off, it cont ro ls the energy sup­
ply to the various electrical components. Data
from battery d iagnosis is cons idered.
Depend ing on the battery's state of charge , indi­
v idual consumers are gradua lly tu rned off to pre­
vent excessive discharge of the batte ry and thus
maint ain s tarting capability.
Dynamic ener gy management
While the vehicle is being driven, dynamic ene rgy
management distr ibutes the energy gene rated
accord ing to the needs of the individual compo-
nents. It regu lates consumption, so that more
II>

electrical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­
ate the limits of physics. Consider that the power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light (•] appears ~
page 33.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time of
year. Abundant electrical energy is required, but
only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situations that you wi ll no­
tice energy management actively regulating the
d istribution of energy.
Vehicl e stands fo r an e xte nded p eriod
If you do not drive your vehicle over a period of
several days or weeks , e lectrica l components are
gradually cut back or switched off . This reduces
energy consumption and maintains starting ca ­
pability over a longer period . Some of the con­
ve nience funct ions may not operate, such as the
interior lights or the power seat adjustment. The
conven ience functions wi ll be available again
when you switch on the ignit io n and start the en­
g ine.
With the engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI* functions ,
the battery is being d ischarged .
If starting capability is jeopardized due to energy
consumption, a message appears in the radio or MMI* display . The message indicates that the
system w ill be switched off automatically in a
Smart T echno log y
moment . If you wish to continue using the func­
tions, you have to start the engine.
With the engin e running
Although electrical energy is generated when the
vehicle is be ing driven, the battery can become
discharged . This happens mostly when litt le en ­
ergy is being generated and a great dea l con ­
s u med and the batte ry's state of charge is not
opt imal.
T o bring the energy ba lance back into equilibri­
u m, consumers which require especially large
amounts of ene rgy are temporarily cut back or
switched off. Heating systems in particu lar re ­
quire a great deal of energy. If you notice, for ex­
amp le, that the heated seats* or the heated rear
window are not heating, they have been tempo ­
rar ily cut back or switched off . These systems w il l
be available again as soon as the energy ba lance
has been restored.
You w ill also notice that engi ne idle speed has
been increased slightly . T h is is normal and not a
cause for concern. By increasing eng ine idle
speed the additional energy requi red is generated
and the battery is ch arged .

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers ):
.,. Do not use full throttle.
.,. Do not drive at engine speeds that are more
than 2/3 of the maximum permitted RPM .
From 600 to 1,000 miles (1,000 to 1,500
kilometers ):
.,. Speeds can gradually be increased to the maxi­
mum perm issib le road or engine speed.
During and after break-in period
.,. Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break•in period
.,. Do not exceed maximum engine speed under
any circumstances.
.,. Upshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
¢page 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
moving parts have been broken in. How well this
break-in process is done depends to a cons idera­
b le extent on the way the vehicle is driven dur ing
the first 1,000 miles (1,500 kilometers).
{[) Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
prog rammed fo r an engine well run-in, not a
new engine.
@ For the sake of the environment
Do not drive with unnecessarily high engine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.

· New tires
If your vehicle is running on new tires, drive very
ca refully for the first 350 m iles (500 k ilometers)
after fitting.
_& WARNING
New tires tend to be slippery and must a lso
be "broken-in" . Be sure to remember this dur­
ing the first 350 m iles (500 k ilometers).
Brake gently. Avoid following closely behind
other vehicles or other situations that might
require sudden, hard brak ing.
Catalytic converter
App lies to vehicles : wit h gasoli ne e ngi ne
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
.,. Always use lead-free gasoline ¢page 213,
Gasoline .
.,. Never run the tank down all the way to empty.
.,. Never put too much motor oil in your engine
¢ page 22 5, Adding engine oil 9::r..
.,. Never try to push- or tow-start your vehicle .
The catalytic converter is an efficient "clean-up"
device b uilt into the exhaust system of the vehi­
cle. The cata lytic converter burns many of the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.
-
The exclusive use of unleaded fuel is c ritica lly im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driv ing and after stopping
the eng ine.
-
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire.

N 1.1'1 ,....,
-Do not apply additional undercoating or
rustproofing on or near the exhaust man i­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
Q) Note
- Be aware that just one tank filling with lead­
ed
fuel will already seriously degrade the
performance of the catalytic converter .
- Do not exceed the correct engine oil level
¢page 225.
-Do not drive until the fuel tank becomes
completely empty . The engine could misfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
l ytic converter to overheat.
- Do not turn off the ignit ion while the veh icle
i s mov ing .
- Do not continue to operate your vehicle un­
der these cond it ions, as otherwise fuel can
reach the catalyt ic converte r. This cou ld re­
su lt in overheating of the converter, requir­
i ng its replacement.
- To assure efficient operat ion of the Emission
Control System:
- Have your veh icle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the em ission control system
and could lead to damage.
@) For the sake of the environment
Even when the Em ission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfu r
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
wit h lead-free super grade gasoline.
Dri ving and th e en vir onm ent
Diesel particulate filter
Applies to veh icles: w ith diesel en gine
The diese l particu late filter filters nearly all of
the soot particles out of the exhaust. The filter
cleans itself automatica lly under norma l driving
conditions. If the filter cannot clean itself (for ex­
ample, because you are only driving short distan­
ces), the filter becomes clogged with soot and
the
II symbol for the diese l particulate filter il­
luminates
¢ page 34 .
_&. WARNING
-Do not park your veh icle over flammab le
materia ls such as grass or leaves because
the high temperature of the diesel particu­
late filter could start a fire .
-
-Do not app ly an underbody protectant in the
exhaust system area or a fire cou ld start.
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 damaged.
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fuel economy, environmenta l impact, and wear
on your engine, brakes and tires largely depend
on three factors:
- your pe rsonal d riving style
- operating conditions
- technical limitat ions
If you ant icipate what you need to do next and
drive economically, you can easily cut your fuel
199

Driving and th e environment
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­ ronment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, wh ich
w ill vary depend ing upon vehicle load and
speed, road and weather conditions, trip
length, etc .
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
"'Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red .
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
"' Try and keep well be low your car's max imum
speed.
Accelerating gently reduces fuel consumption,
engine wear, and does not disturb the environ ­
ment.
Fue l consumption, exhaust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumpt ion w ill be reduced by
one half. Never dr ive faster than the posted
speed lim it and weather conditions 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 en-
gine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop-System*. It is effi­ c ient to sw itch off the eng ine in vehicles w ithout
the Start-Stop-System* when stopped at railroad
crossings and long red lights. Turn ing the engine
off for just 30-40 seconds saves more fuel than is
burned by start ing the eng ine 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 high when
the engine is warming up. So you sho uld drive
away as soon as you start the eng ine and avoid
running at high rpms whi le the engine is s till
warming up.
Q) Note
Do not leave engine id ling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or oth­
er damage to the veh icle or other property.
· Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
"' Have your vehicle serviced at regu lar intervals.
By having your veh icle reg ularly serv iced by an
authorized Aud i dea le r helps to ensure that i t
runs proper ly and economica lly. The condition of
your vehicle not on ly affects its safety and ability
to hold its value, it also affects
fuel consump ­
t ion .
Chec k your oil ea ch t ime y ou fill your tank.
The amount of o il used is re lated to engine load
and speed. .,.

It is normal for the oil consumption of a new en­
gine to reach its lowest va lue after a certain mile ­
age has been driven.
You must d rive yo ur vehicle about 3,000 miles
(5,000 kilometers) before you can properly as­
sess oi l consumption.
This also applies to fuel consumption and engine
output.
(y Note
- Have you r vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
l et. Lack of proper maintenance as well as
improper use of the vehicle will impair the
funct ion of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Contro l System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ign it ion w ires,
valves, wh ich are designed to protect your
vehicle's Emission Control System and other i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.. Try to avoid driving short distances with a cold
engine.
The engine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively.
Just after starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 miles per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy cl imbs to 12 mpg (20 l/100
km) . After about
2.5 miles (4 km), the engine is
at its proper operating temperature and fuel
economy has reached a normal level. So you can
see that you should avoid short trips whenever
possib le.
Driving and the environment
The outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer.

Driving tips
On poor road and offroad, there is always only
one motto: Plan ahead and drive slowly!
P lease observe the followin g when driving away
from paved roads :
~ Drive only on roads and off road sections which
match the des ign of your veh icle and yo ur abili ­
t ies as a driver . Never take risks!
~ Drive slowly and plan ahead!
~ Take into consideration the gr ou nd cle aran ce of
your vehicle.
~ Activate the offroad mode c> page 191 as need­
ed .
~ Use the hill des cent a ssi st <=:> page 193 when
dr iv ing down steep sections on hi lls.
Unp aved roads and offroad
Drive s low ly on unfami liar roads and unknown
offroad sections, and look out for unexpected ob­
stacles (e.g . potho les, rocks, tree stumps, etc .) .
T o prevent the vehicle from bottoming and avoid
damage to the underbody, you should drive
straight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross t he bumps.
Drive briskly through sandy or marshy offroad
sections and do not stop, if at all poss ible.
Driving through water
Note the following to avoid vehicle damage when
driving through water, for example on flooded roads:
- The water must not be any higher than the bot-
tom of the vehicle body .
- Do no t d rive fas ter than wa lking speed.
Driving on a slope
If you ever find yourself not ab le to climb a s lope,
do not try to turn around, drive back down in
re­
ver se.
Othe rwise, you ru n the r isk of tipp ing ove r.
O ffro ad dri vin g
If the vehicle th reaten s to tip over when driving
acro ss a slope, you must immediately stee r
downhill in the direction of the slope.
Do not park you r vehi cle on steep s lopes or
grades.
T o reduce the risk of tipp ing ove r, d rive on s lopes
i n the d irection of t he downwa rd s lope (fall li ne) -
not cro sswi se .
& WARNING ~ -
After driving th rough water, mud, s lush, etc.,
the bra kes may be s low to take effect because
of wet bra ke rotors and pads. Dry the brakes
f irst by brak ing carefully to restore the full
braking effect.
(D Note
- Veh icle components s uch as the engine,
transm ission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch off the Start-Stop-System *
when drivi ng throug h water
r=> page 94.
(D Tips
- Check t he depth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driv ing through
water.
- Keep i n mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely .
-Avo id driving through salt wate r because it
can cause corrosion .
