Hill descent assist brakes all four whee ls auto­
matically in order to limit speed when driving
either forwa rd or reverse on hill s with a grade
up to approximate ly 50% .
When the hill descent assist is on, the current
driv ing speed, when your vehicle entered the
incline is maintained. It is on ly possible to
switch on the assist when driving slower than
37 mph (60 km/h). The assist works between
approximately 2 and 19 mp h (4 and 30 km/
h) . The driver can inc rease or decrease the ve ­
hicle speed within these limits by depress ing
the accelerator or brake pedal In addition, ve­ hicle steerab ility is increased due to the brak-
i ng distribution when driving i n reve rse . ..,.

There must be however sufficient ground ad ­
hesion . The hill descent assist can
not do its
job if the incl ine is icy or if the incline ground
is loose ¢,&..
The system does not work at speeds between
19 and 37 mph (30 and 60 km/h). The system
is then in the ready-mode. The diode in the
button will come on . The system automatical­
ly switched
off when you drive faster than 37
mph (60 km/h) . The diode will go out in this
case.

Hill descent assist is automatica lly act ivated
under the following cond itions:
- the diode in the button illuminates,
- vehicle speed is be low approximate ly
19 mph (30 km/h)
- the incline is 10%.
A WARNING
-Always adapt your speed to the weather,
road and traffic conditions . Do not let
the increased safety provided tempt you
into taking r isks.
- The hill descent assist system cannot
overcome the laws of physics. Your driv­
ing style must always be adapted to the
current road and traffic conditions.
- The hill descent assist may not be able to
hold your vehicle at a constant speed un­
der all condit ions wh ile driving on an in­
cl ine (for example if ground under the
vehicle is loose).
Brake system
Operating conditions and driving habits
The brakes on today's automobiles are st ill
subject to wear, depending largely on operat­
ing conditions and dr iv ing habits ¢& . On
veh icles that are e ither driven mostly in stop­
and-go city traffic o r are driven hard, the
brake pads should be checked by your author- ized Audi dealer more often
than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously. Pump the brakes at inter­
vals .
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing cond itions ice) on the brake pads. A
few careful brake applications should dry
off
the brake pads or remove any ice coatings .
When you are driving at higher speeds with
the windshield wipers on, the brake pads will
briefly touch the brake discs in regular inter ­
vals so as to improve reaction time when brak­
ing on wet surfaces. You, the driver, will not
notice anything.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the b rakes are not used. Here too,
you should clean
off accumulated sa lt coating
from brake discs and pads with a few careful
applications of the brake ¢& .
Corrosion
The re may be a tendency for dirt to build up
o n the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with littl e use of the
brakes.
If the brakes a re not used frequently, o r if cor­
rosion has formed on the discs, it is adv isable
to clean
off the pads and discs by braking
firmly a few times from a modera tely high
speed ¢£ .
IJll-

Fa u lts in th e brake sy stem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circuits may have failed~.&..
Low brak e flu id level
Malfunct ions can occur in the brake syste m if
the brake fl uid leve l is too low. The b rake fluid
l eve l is monito red electronically.
Brake boost er
The brake booster increases the pressure that
you generate w ith the brake pedal.
It only op­
e rates while the eng ine is running or with the
i gnit ion sw itched on (hybr id dr ive*)~ .&,.
Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sa ry, the wheel may be removed for this in­
spection
~ page 2 73, Changing a wheel.
.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too long or too often. This could cause the
brakes to get hot and dimin ish b raking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. Th is may cause the b rakes to
overheat, premat ure wear and increased
stopp ing distance .
- Under certain climat ic and operating
c ondit ions such as passing through wa­
ter, driving in heavy rain 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. Carefully apply brakes
Int ellig ent technolog y 201
for a test . Brakes will dry and ice coat­
ings w ill be cleaned
off after a few care­
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can a lso affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few ca reful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the ai r
f low to the front brakes is not obst ruct­
ed. Otherw ise the bra ke system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one b rake circuit will impair
the braking capab ility result ing in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est a uthorized Audi dea ler or q ualified
workshop.
- Never let the vehicle roll to a stop with
the eng ine shut off .
- If the b rake booster is not working, the
brake peda l must be pressed considera­
bly harder to make up for the lack of
booster assistance.

wheel will be easy to move. Re-ini tialization
might be necessary if the steering wheel was
moved hard to the left and right while the ve­
h icle was not moving . The display turns off if
the initiali zation was successful.
- If the . or

Driving with your
quattro
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-wheel dr ive, power is distributed to
all four wheels. This happens automatically
depending on your driving sty le and the road
conditions at the time . See also ¢
page 197.
A center different ial distr ibutes the dr iv ing
power var iably to the front and rear axle . It
works together with se lective wheel torque control, which activates when driving through
curves
r=:>
page 198.
The all-wheel drive concept is designed for
high eng ine power. Your veh icle is except ion ­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice . Always read and follow
safety precaut ions r=;,
,&.
Winter 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 advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing : these tires must be mounted on
all four
wheels.
See also r=;, page 262, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also app lies to veh icles
with all-wheel driver=;,
page 263, Snow
chains .
Replacing wheels/tires
Vehicles with a ll-wheel drive must always
have tires of the same size. A lso avoid tires
with different tread depths. For deta ils see
page
r=;, page 2 SB, New tires and replacing
tires and wheels.
A WARNING
-Always adjust your dr iv ing to road and traf-
f ic 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 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
could begin to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in­ crease in eng ine speed as w ith a front­
wheel drive veh icle. Always 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 insuff icient ene rgy
avai lab le to s tart the engine .
I ntelligent energy management in your vehi­
cle hand les the d ist ribution of electrical ener­
gy. Starting ab ility is marked ly imp roved and
the life of the battery is extended.
Basically , energy management consists of
b atter y dia gno sis, idling curr ent manag e­
m ent
and dynami c en ergy m anag emen t.
Battery diagnosis
Battery d iagnosis continuously determ ines
the state of the battery . Sensors determ ine
battery vo ltage, battery curren t and battery
temperature. This dete rm ines the current
state of charge and the power of the battery .
Idling current management
Idling current management reduces energy
consumpt ion wh ile the veh icle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy s upply to the va rio us electr ical compo­
nents. Data from battery diagnosis is consid­
ered.
D epending on the batte ry's state of charge,
i nd ividual consumers are grad ua lly turned off
to p revent excessive discharge of the battery
and thus maintain starting capability .
Dynamic energy management
W hil e the vehicle is being driven, dynamic en­
e rgy management dist ributes t he energy gen-
Int ellig ent technolog y 203
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 t hreatened, the indi­
cator light(•] appears¢
page 34 .
What you should know
The highest priority is given to maintaining
star ting capability.
The battery is severe ly taxed in short-distance
driving, in city traff ic and during the cold time
of year. Abundant elect rical energy is re­
quired, but only a lit tle is generated . It is also
crit ical if the engine is not running and electri ­
cal components are turned on. In this in­
stance ene rgy is be ing consumed but none is
being genera ted .
It is in precisely these situations that you will
not ice energy management actively regulat­
ing the d istribution of ene rgy.
Vehicle stand s for an e xtended period
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in­
ta ins start ing capability over a longer pe riod .
Some of the convenience func tions may not
opera te , such as the interior ligh ts or the
power seat adjustment. The convenience
funct ions w ill be available again when you
switch on the ignition and start the engine.
With the en gine turn ed off
If you listen to the radio, for exam ple, w ith
the engine turned off or use other MMI* func-
tions, the battery is being discharged .
11>-
•
•

204 Intelligent technology
If starting capability is jeopa rdized due to en­
ergy consumption, the following warning ap­
pears in the radio or MMI* display:
Please start engine, otherwise system will
switch off in 3 minutes.
The warning ind icates that the system will be
turned off automatically after 3 minutes. If
you wish to continue using the functions, you
have to start the engine .
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven, the battery can be­
come discharged . Thi s happens mostly when
little ene rgy is being generated and a great
deal consumed and the battery's state o f
charge is not optima l.
To bring the energy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular require a great dea l of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has been increased slightly. This is normal and not
a cause for concern . By increas ing engine idle
speed the add it iona l energy required is gener­
ated and the battery is charged.

Driving and
environment
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.
After 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 internal 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, t hese rpm
lim its are programmed for a n engine well
r u n- in, not a new engine.
Driving and environment 205
@) 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 .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 ki lomete rs) afte r they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab
c'.> .&. .
During the brea k-in period, yo u should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mountain passes .
.&, WARNING
New b rake pads don 't have the best stop­
p ing power and must be "broken-i n" dur­
ing the initi al 100 to 150 miles (150 to
200 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing the b rake peda l more firm ly . This also applies
later when new pads are installed.

206 Driving and en vir onm ent
Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
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 i=> page 222,
Gasoline .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 236, Adding engine oil 'l=r. .
.. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
T he temperature o f the exhaust system is
high, both when driving and after stopping
the engine .
- 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.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat sh ields . During driving, the
substance used for u ndercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de­
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
i=>page 236.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec­
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it­
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter i lluminates
i=> page 34. ..,.

A WARNING ,~
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could sta rt.
Avoid damaging the
vehicle
When you are driving on poor roads, o r over
curbs, steep ramps, etc., make ce rtain that
l ow -lying parts such as spoi lers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low ­
slung chassis (sports chassis)* and f ully load ­
ed vehicles.
Shutting down vehicle
I f you wou ld like your veh icle to remain inop­
erative for a longer period of time, contact an
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e.g . corro­
sion prevention, ma intenance and storage.
Pay attention to add itiona l information con ­
cerning the battery. Refer to
c::> page 242 .
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, environmental impact, and
wear on your engine, brakes and t ires largely
depend on th ree factors:
- you r persona l dr iving style
- operating conditions
- technica l lim itations
Dri vin g and en vironm ent 207
If you ant ic ipate what you need to do next and
drive economically, yo u can easily cut yo ur
fuel consumpt ion by 10 -15 percent. T his sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook.
Q) Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, t rip leng th, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac ­
celerating .
.,. Avo id u nnecessary accelerating and b rak ing.
Vehicles use the most fuel when they are ac ­
ce le rat ing . If you ant icipate what is going to
happen next, you will need to brake less and,
thu s, acce le rate less. Le t the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is re d.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.,. Try and keep well below your car 's maximum
speed.
Acce le rat ing gently reduces fue l cons ump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and e n­
gine noise inc rease disproport ionately at high
speeds . If you driv e at app rox imately th ree
quarte rs of top speed, fuel consumption w ill
be reduced by one ha lf. Never d rive fas ter
t han the pos ted speed limi t and weathe r con­
ditions pe rmit.

208 Driving and environment
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 .
The idling phase is automatically reduced for
vehicles with the Start-Stop -System* . It is ef­
fic ient to sw itch
off the eng ine in vehicles
without the Start-Stop-System* when stopped
at railroad crossings and long red lights. Turn­
ing the eng ine
off for just 30-40 seconds
saves more fuel than is burned by sta rting the
engine again .
It takes a long time for the engine to wa rm up
fu lly when it is running at idle. However , wear
and nox ious 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 while the engine is
still 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 resu lt in over­
heat ing or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
.,. Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
consumption. Check
your oil each time you fill your tank.
The amount of oi l used is re lated to engine
load and speed.
It is normal for the oil consumption 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 mi les
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fuel consumption and en­
gine output .
(0 Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
