Operating conditions and driving habits
The brakes o n today's automobiles are still
s u bjec t to wear, depending largely on operat­
ing cond it ions and driving hab its
c::;, &. . On ve­
hicles that a re e it h er dr iven most ly in stop­
and-go city t ra ffi c or are dr iven hard, the
brake pads should be checked by yo ur au thor­
ized Audi dea ler mo re often than specified in
t h e
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result in reduced brake performance.
On steep slopes , you sho uld use the braking
effect of the engine. This way, you prevent un­
necessary wear on the brake system . If you
must use your b rakes, do not hold t he brakes
down continuous ly. Pump the brakes at in ter­
vals .
Moisture or road salt
U nd er certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads . A
few caref ul brake applicat ions should dry off
t h e b rake pads or remove a ny ice coatings .
The effectiveness of the brakes ca n be reduced
when the vehicle is d riven on a sa lt-covered
ll>

road and the brakes are not used. Here too,
you shou ld clean off accumu lated salt coating
from brake discs and pads with a few carefu l
applications of the brake
c> ,&. .
Cor rosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean off the pads and discs by brak ing
f irmly a few times from a moderately high
speed
c> &, .
Fau lts in th e bra ke s ystem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
ci rcu its may have failed
c> ,&. .
Low brak e fluid l evel
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid
leve l is monitored electronically.
Brake lining w ear 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
sary, the wheel may be removed for this in­
spection
c> page 262, Changing a wheel .
8_ WARNING
-You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road condit ions permit.
Other road users must not be put at r isk -
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 lo ng or too often. This cou ld cause the
brakes to get hot and dimin ish b raking
effi ciency.
Int ellig ent technolog y 193
-Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain cl imatic and operat ing
conditions such as passing through wa­
ter, dr iv ing in heavy rain or after washing
the vehicle, the effectiveness of the
b rakes can be reduced. In winte r, ice can
accumulate on the brake pads , lin ings,
discs and drums . Carefu lly app ly brakes
for a test . Brakes will dry and ice coat­
ings wi ll be cleaned off after a few care­
fu l brake applications.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can a lso affect braking efficiency.
Clean off accumu lated salt coating from
brake discs and pads with a few careful
brake applications .
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brake system could
overheat reduc ing the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
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 udi dealer or qualified workshop .
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pres­
su re which is created only whe n the engine is
runn ing

Replacing wh eels/ tire s
Vehicles w ith All Wheel Dr ive must always
have tir es of the same size. Also avoid tires
with different tread depths. For details see
pag e¢
page 249 , N ew tires and replacing
tires and wheels .
Off-Road driving?
Your Aud i does not have enough ground clear­
ance to be used as an off -road vehicle. It is
therefor e best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
¢ page 198.
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 Drive is very ef­
fective, always remember that braking
capacity is limited by t ire traction . Yo u
should the refore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be ca reful not to
dr ive too fast because the front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). If this sho uld occ ur, 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 wh ich 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 optimi zes the
availability of electrical energy for starting the engine.
If a vehicle wit h a conventional energy system
i s not driven for a long period of time , the bat­
tery is discharged by idling cu rrent consumers
(e .g. immobilizer) . In certain circumstances it
can result in there being ins ufficient energy
avai lab le to start the engine.
Int ellig ent technolog y 195
Intelligent energy management in your vehi ­
cle hand les the distribution of e lectrica l ener­
gy. Start ing ability is marked ly improved and
the life of the b attery is extended.
Bas ica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent m anage­
ment
and dynamic energ y management.
Battery diagnosis
Battery diagnosis continuously de termines
the state of the battery . Sensors de termine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the batte ry .
Idling current management
Id lin g cur ren t 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 diagnos is is cons id­
ered.
Depend ing on the battery's state of cha rge ,
individua l cons umers are gradually turned off
to prevent excessive discharge of the batte ry
and th us maintain starting capability .
Dynamic energy manag ement
While the ve hicle is being driven, dynamic en ­
ergy management distrib utes the energy ge n­
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 .
@ Tips
-But even energy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a battery are
limited.

196 Intelligent technology
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 electr ical energy is re­
qu ired, but only a little is generated. It is also
cr itical if the e ngine is not run ning and elect ri­
cal components a re turned on. In th is in­
stance energy is being consumed but none is be ing generated .
I t is in precisely these situations that you w ill
notice energy managemen t actively regulat ­
ing the distrib ution of energy.
Vehicle stands for an ext ended period
If you do not drive your vehicle over a period
of severa l days or weeks, elect rical compo­
nents are grad ually cu t back o r switched off .
This reduces energy co nsu mption and main­
tains starting cap abili ty
over a longer period.
Be aware that when you unlock you r vehicle,
some of the conve nience funct ions may not
ope rate, such as the Convenience key , the re­
mote cont ro l or the power seat adjustment .
The convenience functions will be availab le
aga in when you switch on the ignition and
start the engine .
With the engine turned off
If yo u lis ten to the radio, for example, with
the eng ine turned off or use othe r MM I fu nc­
tions, the battery is being discharged .
I f sta rting capability is jeopa rdized due to e n­
e rgy consumpt ion, the fo llow ing warning ap­
pears in the MMI disp lay :
Please start th e engine soon or th e syst em
will be turned off .
The warning ind icates that the system will be
turned off automatically after 3 m inu tes .
If
you wish to cont inu e us ing the functions , you
have to start the engine.
With the engine running
Although e lec trical energy is generated when
the vehicle is being driven, the battery can be ­
come discharged. This happens mostly when
li ttle energy is being generated and a g reat
deal consumed and the battery's state of
charge is not optimal.
To b ring the energy ba lance back into equili­
brium, consumers which req uire especially
l arge amounts of energy are temporar ily cut
back or sw itched off. Heat ing systems i n par­
ticular require a great deal of energy. If you
notice , for example, that the heated seats* o r
the heated rear window are not heating, they have been temporarily cut back or sw itched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engi ne idle speed has
been increased slightly . Thi s is normal and not
a cause for con ce rn. By inc reas ing eng ine id le
speed the addi tional energy requ ired 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 fir st 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 .
.. Avoid high engine speeds .
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers):
.. Speeds can gradually be increased to the
maximum pe rm iss ib le road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to high speeds
when it is cold. This applies whether the
transmission is i n N (Neutra l) or in gear.
After the break- in peri od
.. Do not exceed maximum engine 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
i n. How well this break-in p rocess 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 ki lome ters).
(D Note
Extremely h igh engine speeds are auto­
mat ica lly reduced. However, t hese rpm
lim its are progr amme d for an eng ine well
r u n- in, not a new engine .
Driving and environment 197
@) 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
particularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
.&, 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 a re installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&, .
D uring 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 mounta in passes .
.&, WARNING
New b rake pads don't have the best stop­
p ing power and mu st be "broke n-i n" dur­
ing the initi al 100 to 150 miles (150 to
2 00 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing the b rake peda l more fi rm ly . This also applies
later when new pads are installed.

198 Driving and en vi ro nment
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 218,
Fuel supply.
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 22 7, Adding engine oil 't=r. .
• Never try to push- or tow-star t your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. 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 l ife of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r 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 shie lds . During driving, the
substance used for undercoating could
overheat and caus e a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the perfo rmance of the catalytic
conve rter .
- Do not exceed the correct engine oil leve l
¢page 227.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . Un burned f uel could a lso get into the exhaust system and th
is co uld cause
the cata lytic converter to overheat .
- Do not switch
off the ignition while the
vehicle is moving .
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control Sys tem is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke ex haust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is es peci ally true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .

Driving through water
on roads
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
bottom of the vehicle body.
- Do not drive faster than wa lking 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. Dry
the brakes first by braking carefully to re­
store the full b raking effect.
([) 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 dr iv­
i ng 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 vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can cause corrosion.
Dri vin g and en vironm ent 199
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 eng ine, brakes and tires largely
depend on three factors:
- your personal d riving style
- operating 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 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the environment and your pocketbook.
@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Tra nspo rt Canada may not corre­
spond to your actual consump tion on the
road, which will vary 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 are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most f uel when they are ac­
ce le rating. If you ant icipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less . Let the vehicle coast
whenever possible - for examp le when you see
that the next traff ic light is red.
•
•

200 Driving and en vi ro nm ent
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. F ue l consumption, exhaust em issions and en ­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions 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 veh icle by letting the
engine run at idle .
It makes sense to shut
off the e ngine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings , or at traff ic lights that have
long wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
burned s tarting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle . Howeve r, wear
and noxious em issions 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 .
([) Note
Do not leave engine idling unattended af ­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over- heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"' Have your ve hicle serviced at reg ular inter -
vals.
By having your veh icle regu larly serviced by an
Audi dealer he lps to ensure that it runs p rop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its value, it also affects
fuel c onsump­
tion .
Check your oil e ach time you fill your t ank .
The amount of oil 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 certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your vehicle maintained proper ly
and in accordance with the service rec ­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alte r or remove any device, such
as heat sh ie lds, switches, ign it ion w ires,
valves, which are designed to protec t
your vehicle's Emission Control System
and other impo rtant vehicle compo­
nents .

202 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, please remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
(D Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
i::> page 202, Operating instructions .
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­ ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems. From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind~ &.
Trailer brakes
If your trailer is equipped with a brak ing sys­
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
direc tly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your Audi dealer for correct
wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is io n to the rear .
A WARNING ,~ -
After removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.

pe rmissible, while keep ing the trailer as light
as possible under the circumstances. Whenev­
er possib le, transfer some cargo to the lug­
gage compartment of the tow veh icle while
observing tongue load requirements and vehi­
cle load ing considerations.
Spee d
The higher the speed, the more difficult it be­
comes for the dr iver to control the rig . Do not
drive at the maximum permissible speed . Re­
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icu larly
when going downhill.
Reduce vehicle speed
immediately if the trail­
er shows the slightest sig n of swaying.
Do not
try to stop the swaying by acc eler ating .
Observe speed limits. In some areas, speeds
for vehicles towing trailers are lower than for regular vehicles.
A lways apply brakes ear ly . When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant t emperatu re
The coolant temperature gauge¢ page 10
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds . Re­
duce your speed immed iate ly if the LEDs in
the top pa rt of the display turn o n.
For more informat ion about indicator lights,
refer to. ¢

A WARNING
Anyone not p roperly restrained in a mov­
ing veh icle is at a much greater risk in an
accident. Never let anyone r ide in your car
who is no t prope rly wear ing the restra ints
provided by Aud i.

Trailer towing tips
Important to know
You r ve hicle handles d ifferently when towing
a trai le r be cause of the additional weig ht and
differen t weigh t distr ib ution. Sa fety, per fo rm­
ance and economy will great ly depend on how
carefully you load your trai ler and operate
your rig.
Be fore you act ua lly tow yo ur tra iler, p ract ice
tu rning, s topping and backing up in an area
away from t raffic . Keep practicing unti l yo u
have become completely familiar wit h the way
yo ur vehicle-tra ile r combination behaves and
responds.
Backing up is diffic ult and requires practice .
Bac king up w ith a trailer gene rally req uires
stee ring action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater d istance between your ve­
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
