You can compensate for this by press ing
the brake pedal more firm ly. This also
applies later when new pads are instal­
led .
- You should perform brak ing maneuvers
for the purpose of clean ing the brake
system only if road cond it 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 lowe r
gear or lowe r driving range. Do not ride
the brakes or hold the pedal down too long or too often . This cou ld cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when yo u do not intend
to brake. Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy rain or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice ca n
a ccumulate on the brake pads, linings,
dis cs and d rums. Carefully apply brakes
f or a test . Brakes will dry and ice coat­
ings will be cleaned off after a few ca re ­
ful brake applications.
- Driv ing fo r an ex tended period of time on
salt-covered roads without using your
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 install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . Otherwise the brake system co uld
overheat reducing the effectiveness of
t h e ent ire brake system.
- Failur e of one bra ke c ircuit will impair
t h e braking capability resulting in an in­
cr eased stop ping distan ce. Avoid driv ing
the vehicle and have it towed to t he near-
Int ellig ent technolog y 189
est a uthorized Audi dea ler or q ualified
workshop.
- Never let the ve hicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
examp le when towing you r vehicle, or
because the brake booster has somehow
been damaged, the bra ke pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

Driving with your
quattro ®
Applies to vehicles: with all-wheel drive
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-whee l drive, power is distribute d to
a ll fo ur whee ls. This happens automat ica lly
d epending on your dr iving sty le and the road
conditions at the t ime. See also¢
page 185 .
A cen ter different ial d istr ib ut es the dr iv ing
power var iably to the front and rear axle. It
wo rks together with se lective whee l torque
control, which activates when driving throug h
curves ¢
page 186. With the sport differen ­
tial*, power distribution to the rear wheels is
variable and can be adjusted with Audi drive se lect ¢
page 109 .
The all-wheel drive concept is designed for
h igh engine power . Your vehicle is exception­
ally powerful and has exce llent dr iving charac ­
terist ics bot h under normal driving conditions and on snow and
ice . Always read and follow
safety precautio ns ¢ &. .
Winter tires
When driving in t he win ter, yo ur vehicle wi th
all-wheel d rive h as an adv antage, eve n w it h
r egular tires. In wi nte r road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved driveability and brak­
i ng : these tires must be mounted on
all fou r
wheels . See also ¢ page 246, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this no rma lly also app lies to ve hicles
with all-wheel drive¢
page 247, Snow
chains .
Replacing wheels/tires
Vehicles wi th a ll-wheel drive m ust always
have ti res of t he same s ize. A lso avoi d tires
with differe nt t read depths . For detai ls see

page 242, New tires and replacing
tires and wheels.
Off-Road dr iving?
You r A ud i does no t have e nough gro und clea r­
ance to be used as an off -road vehicle .
It is
t h e refore best to avoid roug h tracks and u n­
even te rrain as much as possib le . Also refer to
¢ page 193.
A WARNING
Always ad just 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 ext ra risks .
-Al though the a ll-wheel drive is ve ry ef­
fective, always remember that braking capacity is lim ited by tire t raction. You
s hould t herefore no t drive at ex cessive
speeds on i cy or slippe ry road surfa ces.
- On wet road surfa ces, be careful not to
d rive too fast because the fr on t whee ls
could begin to slide on top of the water
(aquaplaning) . If thi s should occur, 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 optimizes the
availability of electrical energy for starting
the engine.
If a vehicle with a conventional energy system
i s not driven for a long period of time, the bat­
tery is discharged by idling current consumers
(e.g. immobilizer) . In certain circumstances it
can result in there being insufficient energy
avai lab le to start the engine.
I ntelligen t energy management in your vehi­
cle handles the distribution of electrical ener­
gy . Starting ability is marked ly improved and
the life of the battery is extended .
Basically, energy management consists o f
battery diagnosis, idling current manage­
ment
and dynamic energy management.
Battery diagnosis
Batt ery d iagnosis continuously dete rmines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
I dling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various electrica l compo­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus mainta in start ing capability.
Intelligent technology 191
Dynamic energy management
While the vehicle is being driven, dynamic en­
ergy management distrib utes the energy gen ­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more e lectrical energy is not being used
than is being generated and ensures an opti­
mal state of charge fo r the battery .
{!) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited .
- If start ing ability is threatened, the indi­
cator light(•] appears¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short-distance
driv ing, in city traff ic and during the cold time
of year. Abundant electrical energy is re­
quired, but on ly a little is generated . It is also
c rit ical if the engine is not running and electri­
ca l components are turned on. In this in­
stance ene rgy is be ing consumed but none is
being generated .
It is in precisely these situations that you will
notice energy management actively regulat­
in g the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electr ical compo ­
nents are gradually cut back or switched off .
T h is reduces energy consumption and main­
tains starting capability over a longer period .
Some of the convenience functions may not
operate, such as the interior lights or the
power seat adjustment. The convenience
functions will be available again when you
switch on the ignition and start the engine.

192 Intelligent technology
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use othe r MMI func­
tions, the battery is being discharged .
If sta rting capability is jeopa rdized due to en­
e rgy consumpt ion, the fo llowing warning ap­
pears in the MMI display:
Please start the engine soon or the system
will be turned off.
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 . This happens most ly when
l ittle energy is be ing generated a nd a great
deal consumed and the battery's state of
cha rge is not optimal.
To br ing the energy balance back into equili­
b rium, consumers which require especially
la rge amounts of energy are tempo rarily cut
back or switched off. Heating sys tems in par­
ticular requi re 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 ba lance has been restored.
You will a lso notice that engine idle speed has
been increased slightly. This is norma l and not
a cause for concern . By increasing engine idle
speed the add itional energy required is gener­
ated and the batte ry is charged.

@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
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 you r engine, bra kes and t ires largely
depend on th ree factors:
= your persona l dr iving style
- operating conditions
- technica l lim itations
I f you anticipate what yo u need to do next and
drive economically, you can easi ly cut your
fuel consumption by 10-15 percent. This sec­
tion will give you some t ips on how you can
he lp the environment and your pocketbook.
@ Tips
The consumpt ion estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ich will vary depending upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
" Avoid unnecessary accele rat ing and braking.
Dri vin g and en vironm ent 195
Vehicles use the most fue l when they a re ac ­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
" Try and keep well below your car's maxi-
mum speed.
Acce lerating gently red uces fue l cons ump­
tion, engine wear, and does not disturb the environment.
Fuel consumpt ion, exhaust emiss ions and en ­
gine noise increase disproportionately at high
speeds . If you drive at approximately th ree
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions perm it.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
" Shut the eng ine off when you are not driv­
ing the vehicle.
" Do not warm up the ve hicle by letting the
eng ine run at idle .
It makes sense to shut off the engine in traffic
jams, when wa it ing for tra ins to pass at rail­
road crossings, or at traffic lig hts t hat have
long waits on red . T ur ning the eng ine off for
just 30-40 seconds saves mo re fuel than is
bur ned star ting the e ngine again.
It takes a long t ime for the engine to warm up
fully when it is run ning at idle . However, wea r
and noxious emissions are espec ia lly high
whe n the eng ine is wa rm ing up. So yo u shou ld
drive away as soon a s you start the e ngine and
avo id r unning at high rpms whi le the engine is
still warming up.

(0 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 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 vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fu el
con sump tion .
C heck your oil each time you fill your tank.
The amount of oil used is related to engine
l oad and speed.
I t is normal for the oil consumption o f a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You mus t drive yo ur vehicle abo ut 3,000 miles
(5,000 kilometers) be fo re yo u can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output.
(]) Note
-Have yo ur vehicle maintai ned properly
and in accordance with the service re c­
ommendations in your War ran ty
& Mai n­
tenance bookle t. Lack of proper mainte ­
nance as well as imp roper use of the
ve­
hicle will impair the function of the
emission control system and could lead
to damage. -
Do not alter or
remove any component of
the Emission Control System unless ap­
proved by the manufacturer .
- Do not alter or
remove any device, such
as heat shie lds, switches, ignition w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
oper ating temperature to
reduce fuel consumpt ion and nox ious em is­
s ions effectively.
Just after starting, a co ld engine in a mid-size
car on ly achieves a fuel economy of 6-8 m iles
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 miles (4 km),
the engine is at its prope r operating tempera­
tu re and fuel economy has reached a normal
level. So you can see that yo u should avo id
short trips whenever poss ible.
T he
outside temperatur e is also cr it ical in t his
regard. Your car consumes more fue l in the
winter tha n in the s umme r.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind

Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.

Safety chains
Alw ays use s afety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r lights m ust meet all reg ulations . Be
su re to check w ith your authorized Audi dealer
fo r c orrec t w iri ng, sw itches, and relays.
Mirrors
If you a re unable to see the traffic behind you

198 Trailer towing
Tire pre ss ure
When towing a trai le r, inflate the t ires of your
vehicle to the co ld tire pressure listed under
"Full load" on the label located on the driver 's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac ­
turers' specifications.
Light s
The headlight settings should be checked with
the trailer attached before dr iving off. Check
to make sure both vehicle and tra iler lights
are working properly.
Saf ety chains
Be sure tra iler sa fe ty cha ins a re p roperly con­
nected from the trailer to the hitch on the ve ­
hicle. Leave eno ugh slack in the chains to per ­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when you are driving.
The chains shou ld cross under the trai ler
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling o f vehicle
and trai ler, p lease note the following:
.,. Do not tow a loaded tra iler whe n your car it ­
self is no t loaded .
.,. Be especia lly careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed.
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weigh t di stribution
Towing a loaded trai ler with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avo ided, drive at very
low speeds only to avoid the risk of losing
steer ing control. A "ba
lanced' ' rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keep ing the trai ler as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com ­
partment of the tow veh icle while obse rving
tongue load requ irements and vehicle load ing
considerations.
Speed
The higher the speed, the more d iff icu lt it be­
comes for the driver to control the rig. Do not
drive at t he maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -pa rtic ularly
whe n going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do n ot
try to sto p th e swaying by acc elerating .
Observe speed limits. In some areas, speeds
fo r vehicles tow ing tra ile rs a re lower than for
regular veh icles .
Always apply brakes early. When driving downh ill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . U se of
the brakes alone can cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge c> page 10
must be observed carefu lly. If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
i n t he i nstrument cluster starts flashing, pull
off the road, stop and let the engine
idle for
abo ut two min utes to prevent he at build-up .
_& WARNING
Anyone not proper ly restra ined in a mov ­
i ng vehicle is a t a much greater risk in an
accident . Never let anyone ride in yo ur car
who is not p roperly wea ring the rest raints
prov ided by Audi.
