Intelligent Technology
Braking
What affects braking efficiency?
New brake pads
During the firs t 25 0 miles (400 km), new b rake
pads do not possess their full braking effect , they
have to be "broken i n" first ¢& . You can com­
pensate for this slight ly reduced braking power
by push ing harder on the brake pedal. Avoid
heavy braking loads during the break-in period .
Operating conditions and driving habits
The brakes on today's automobiles a re still sub ­
ject to wear, depend ing largely on ope rating con ­
ditions and driving habits¢& . On vehicles that
are either dr iven most ly in stop-and-go city traf­
f ic or are driven hard, the brake pads should be
checked by you r authorized Aud i dea ler more of­
ten than spec ified in the
Warranty & Mainte­
nance booklet .
Failu re to have your brake pads
i n spected c an resu lt in reduced bra ke pe rform­
ance.
O n steep slopes, you sho uld use the braking ef ­
fect of the eng ine . This way, you prevent unnec­
es sary wear on t he b rake system. If yo u m ust use
your b rake s, d o not hold the brakes down cont in­
uously. Pum p th e b rakes at intervals.
Operating noise
Noises may occur when brak ing depend ing on the
speed, b raking force and outs ide cond it ions such
as tempe ra tu re and humidi ty.
Effect of water and road salt
In certain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnig ht con ­
densat ion or after washing your car, the b raking
effect can be reduced by mo isture or ice on the
b rake rotors and b rake pads . T he brakes must be
d ried first w ith a few careful b rake a pplica tions.
At highe r speeds and with t he windsh ield wipers
tur ned on, the br ake pads press aga inst the brake
rotors for a sho rt amoun t of time. This occur s at
regular intervals w it h out t he dr iver noticing and
p rov ides for better bra ke response time under
wet conditions.
180
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and t he b rakes are not used . Likewise, yo u clean
off accum ulated salt coating from brake discs
and pads with a few caut ious app lications of the
brake ¢& .
Corrosi on
There may be a tendency fo r dirt to build up on
the b rake pads and corrosion to form on the discs
i f the car is not driven regu larly or only for short
trips with little use of the brakes .
If the bra kes are not used frequent ly, or if corro­
s ion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢ &.
Faults in th e brake system
If you shou ld notice a sudden increase in brake
pedal travel , then one of t he two brake circu its
may have failed¢& .
Low brake fluid level
Malfu nctions can occu r in the brake system if the
br ake fluid level is too low . The brake fluid leve l
is mo nitored electronica lly .
Brake booster
The bra ke booster i ncreases the press ure t hat
yo u ge nera te with the brake ped al.
It works only
whe n the eng ine is ru nning .¢ &
Brake lining wear status
Brake lining wea r may be c hecked by visua l in­
spection o f the condition of the brake pads
t hr ough t he openings in t he wheel. If necessary,
t h e wheel m ay be removed fo r thi s inspe ction
¢ page 240, Replacing wheel s.
_& WARNING
- New brake pads don't have the be st sto p­
ping power and m ust be " broken-in" du ring
the initial 250 miles (400 kilometers). You
can compensate for this by p ressing the
brake pedal more firmly. This also app lies
later w hen new pads are installed.

..... N
0 ::..:: co ..... ..... -You should perform braking maneuvers for
the p urpose of clean ing the brake system
only if road conditions permit. Other road
users must not be put at risk - you may
cause an accident!
- Before descend ing a steep grade, reduce
speed and shift transm iss io n into a lower
gear or lowe r d riv ing range. Do not ride the
bra kes or hold the pedal down too long or
t oo often. This could ca use the bra kes to get
hot an d diminish brak ing efficiency.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
br ak e. This may cause the br akes to over­
heat, p remat ure wea r and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tions such as passing thro ugh water, driving
in heavy ra in or after washing the vehicle,
the effectiveness of the brakes can be re ­
duced. In w inte r, ice can acc umulate on the
brake pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings w ill be cleaned off after a
few careful b rake applica tions.
- Driv ing for an ex tended period of time on
salt-covered roads witho ut using your
bra kes can also affe ct bra king efficie ncy .
C le an off a ccumula ted s alt co ating from
bra ke discs and pads with a few caref ul
bra ke app lications.
- If you dam age the fro nt sp oiler, or if yo u in­
st all a diff erent spoi le r, be sure the ai r flow
to the front brakes is not obstr ucte d. Othe r­
wise the bra ke system could overheat reduc ­
ing the e ffectiveness of the entire b rake sys­
tem.
- Failure of one brake circuit will impair the
brak ing capability resulting in an increased
stopp ing distance. Avoid driving the vehicle
and have it towed to the nearest authorized
Audi dealer or qualif ied workshop.
- Never let the veh icle roll to a stop w ith the
engi ne shut off .
-If the brake booster is not working, the
bra ke pedal m ust be pressed conside rably
harder to make up for the lac k of booster
assista nee .

Driving with your
quattro
Applies to veh icles: w ith all-wheel drive
With all-wheel drive, all four wheels are driven.
General information
With all-whee l drive, power is distributed to all
four wheels . This happens automatically depend­
ing on your dr iv ing style and the road condit ions
at the time . See also ¢
page 177 .
A center differentia l distrib utes the driv ing power
variably to the front and rear axle. It works to­ gether with selective wheel torque control, which
activates when driving through curves
¢
page 178 . With the sport differentia l*, power
d istr ibut io n to the rear wheels is variable and can
be adj usted w ith d rive select¢
page 111.
The all -wheel drive concept is designed for high
engine power . Your veh icle is exceptionally pow­
erful and has excellent driving characterist ics
both under normal dr iv ing condit io ns and on
snow and ice. Always read and fo llow safety pre­
cautions ¢
A.
Winter tires
When d rivi ng in the winter, your vehicle with all­
wheel drive has an advantage, eve n with regular
tires. In winter road conditions it may be adv isa­
b le to mount w inte r ti res (or all-season tires) fo r
improved driveability and braking: these tires
must be mounted on all four wheels . See a lso
¢ page 232, Winter tires.
Tire chains
Where ti re chains are mandatory on certain
roads, this norma lly also applies to vehicles w ith
all -whee l drive ¢
page 233, Snow chains .
182
Replacing wheels /tires
Vehicles with all-wheel d rive must a lways have
tires of the same size. Also avoid t ires with differ ­
ent tread depths. For detai ls see page
¢ page 224, New tires or wheels .
Off-Road driving?
You r A udi does not have eno ugh ground clear­
an ce to be used as an off-road vehicle.
It is there­
fore best to avoid ro ugh tracks and uneven ter ­
rain as much as possib le. Also refer to
¢ page 185.
A WARNING
A lways adjust your dr iving to road and traffic
conditions . Do not let the extra safety afford­
ed by all-whee l drive tempt you into taking
extra risks .
- Although the all-wheel drive is very effec­
tive, always remember that braking capacity
is limited by ti re tract ion. You s hou ld there­
fore not drive at excessive speeds on icy or
slippe ry road s urfaces.
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be­
gi n to slide on top of the water (aquaplan­
ing) . If th is should occur, you will have no
warning from a s udden increase in engine
speed as with a front-wheel drive vehicle.
Always drive at speeds which are suited to
the road conditions -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 batte ry is
discharged by id ling current consumers (e.g . im­
mobilizer). In ce rtain circumstances it can resu lt
i n the re being insufficient energy avai lab le to
start the engine .
Intelligent energy management in yo ur vehicle
hand les t he d istribution of elect rical energy. .,.

..... N
0 ::..:: co ..... ..... Starting ability is marked ly improved and the life
of the battery is extended.
Basically, energy management consists of
bat ­
t e ry di agno sis, idl ing curr ent mana gement
and
dy namic en ergy management .
Battery diagnosis
Battery diagnosis continuous ly determines the
state of the batte ry . Sensors dete rm ine battery
voltage, batte ry current and battery tempera­
ture . This determ ines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumpt io n while the veh icle is stand ing . With the
i gn it ion sw itched off, it controls the energy sup­
p ly to the various ele ctrical components . Data
from battery diagnosis is considered.
D epending on the battery's state of charge, ind i­
vid ual consume rs a re gradually turned off to p re­
vent excessive discharge of the battery and thus
maintain starting capability.
Dynam ic energy management
While the vehicle is being driven, dynamic energy
management dist ributes the ene rgy generated
accord ing to the needs of the individual compo ­
nents . It regulates cons umption, so that mo re
e lectrica l energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
@ 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

What you should know
The highest priority is given to maintaining start­
ing capability.
The ba tte ry is severely taxed in short -d istance
driving, in city traffic and d uring the co ld time of
year. Abundant electrical energy is requ ired, but
Intellig ent Technology
on ly a little is generated . It is a lso 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 will no ­
tice energy management actively regulating the distribution of energy .
Vehicle stands for an extended period
If you do no t drive your vehicle ove r a period of
severa l days o r weeks, electrical 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
venience functions may not operate, such as the interior lights or the power seat adjustment. The
convenience functions will be ava ilable aga in
when you switch on the ignition and start the en­
gine.
With the engine turned off
If you listen to the rad io, for example, with the
engine turned off or use other MMI funct ions,
the battery is being d ischarged .
If starting capab ility is jeopardized due to energy
consumption, a message appears in the MMI dis­
play . The message ind icates that the system will
be switched off automat ica lly in a moment . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.
With the engine running
Although e lectr ical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en­
ergy is being generated and a great dea l con­
s u med and the batte ry's state of charge is not
optimal.
T o bring the energy balance back into equilibr i-
um, consumers w hich require espec ia lly large
amounts of ene rgy are tempo rar ily cut back o r
swi tched off . Hea ting systems in particular re-
quire a great de al of energy. If yo u no tice, fo r ex­
amp le, that the heated seats * or the heated rear
window are not heating, they have been tempo ­
rarily cut bac k or switched off. These systems will .,..
183

Intelligent Technology
be ava ilab le aga in as soon as the energy balance
has been restored.
You will a lso not ice tha t engine idle speed has
been inc reased slightly. This is normal and not a
cause for concern. By increasing eng ine idle
speed the additiona l energy required is generat ­
ed and the battery is cha rged .

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 kilometer s):
"' 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 maxi­
mum pe rm issib le road or engine speed .
During and after break-in pe riod
"' 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 c ircumstances.

During the first few hours of driving, the eng ine's
internal friction is higher than later when all the
mov ing parts have been broken in . How well this
b reak-in process is done depends to a considera­
b le exte nt on the way the veh icle is d rive n during
t he first 1,000 miles (1,500 kilometers).
(D Note
Extremely high eng ine speeds a re au toma ti­

Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur­
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight

Avoid damaging the
vehicle
When yo u are dr iv ing o n poor roa ds, or over
cur bs, stee p ramps, e tc., ma ke cert ain that low­
ly ing parts s uch a s spo ile rs a nd exh aust sy stem

185

Driving and th e en vironm ent
(D Tips
- Check the depth of the water before driving
through it .
- Do not stop 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 veh icle to drive
through safely.
- Avoid driving through salt water because it
can cause corrosion .
Catalytic converter
It is very impor tant tha t your emission con trol
system (ca talytic converter) is functioning prop ­
erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline ¢ page 198,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 20 7, 9::?l Adding engine oil .
~ Never try to push- or tow-start you r vehicle.
The cata lytic converter is an efficient "clean-up"
dev ice bu ilt into the exha ust system of the vehi­
cle. The cata lytic conve rter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the life of the catalytic conve rter and
p roper functioning of the engine.
A WARNING ,..____ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park or ope rate t he vehicle in areas
where t he hot exha ust system may come in
contact with dry grass, br ush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani-
186
fold, exha ust pipes, cata lytic conve rter or
heat shields . D uring driving, the substance
used for undercoat ing could overheat and
cause a f ire .
Cl) Note
-Be aware that just one tank f illing wit h
leaded fu e l w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
¢page 207.
-Do not drive until the fue l tank becomes
completely empty . The engine could mis­
fire. Unbu rned fue l cou ld also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not turn off the ign ition while the vehicle
is moving .
- Do not continue to operate your vehicle un­
der these conditions, as otherw ise fuel can
reac h the catalytic converter . T hi s could re ­
sult in overheat ing of the converter, requir­
ing its replacement.
- T o ass ure eff icient ope rat ion of the Emis­
sion Contro l System:
- Have you r vehicle maintained properly and
i n accordance wit h the service recommen­
dations in your Warranty & Ma intenance
booklet.
- Lack of proper ma intenance as well as im­
p roper use of the veh icle will impa ir the
function of the emission control system
and could lead to damage .
(® For the sake of the environment
Even when the Emission Control System is op­
erating properly, t he exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. Th is depends on the sulfur
con tent of the fuel being used . Us ing a d iffer­
ent brand of fuel may help , or fi lli ng the tank
wi th lead-free super g rade g asoline.

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.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles 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
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red .
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately 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 cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty.

Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
.,. Have your vehicle serviced at regular intervals.
By having your vehicle regu larly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and econom ically . The condition of
your veh icle not only affects its safety and ability
to hold its value, it also affects
fu el consump­
tion .
C he ck your oil e ach t ime you fill you r ta nk .
The amount of oil used is re lated to engine load
and speed.
It is normal for the oil consumpt ion of a new en­
g ine to reach its lowest val ue afte r a certa in mile­
age has been driven .
You must d rive you r vehicle about 3 ,000 miles
(5,000 k ilome ters) before you can p roperly as ­
sess o il cons umption .
This a lso applies to fuel consumption and engine
outpu t.

· Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid driving short distances with a cold
eng ine .
T he eng ine and catalytic converter have to reac h
their opt imal
operating temper atu re to reduce
fuel consumpt ion and noxious emiss ions effec­
tively .
Just after start ing, 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
mile, fuel economy climbs to 12 mpg (20 l/100
km) . After about
2 .5 m iles (4 km), the engine is
at its proper operating temperatu re and fuel
economy has reached a no rma l level. So you can
see that you should avoid sho rt tr ips wheneve r
possible .
The
out sid e temperatur e is also cr it ica l in th is re­
gard. Your car cons umes more fue l in the winter
than in the summer.
