Driving Safely ---------------------" ~'----
Use only floor mats that leave the pedal area unobstructed and that
are firmly secured so that they cannot slip out of position . You can
obtain suitable floor mats from your authorized Audi dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached to these fasteners.
Properly securing the floor mats will prevent them from sliding into
positions that could interfere with the pedals or impair safe opera­
tion of your vehicle in other ways .
& WARNING
Pedals that cannot move freely can result in a loss of vehicle
control and increase the risk of serious personal injury.
• Always make sure that floor mats are properly secured.
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to
control the vehicle.
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning.
• Always make sure that objects cannot fall into the driver foot­
well while the vehicle is moving. Objects can become trapped under the brake pedal and accelerator pedal causing a loss of
vehicle control. •

Unfastening safety belts
Unbuckle the safety belt with the red release button only
after the vehicle has stopped.
Fig . 176 Releasing
the tongue from the
buckle
- Push the red release button on the buckle=> fig. 176. The
belt tongue will spring out of the buckle=>& .
- Let the belt wind up on the retractor as you guide the belt tongue to its stowed position.
& WARNING
Never unfasten safety belt while the vehicle is moving. Doing so
will increase your risk of being injured or killed. •
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
ries.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly
positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and will even increase the
risk of injury and death by moving the safety belt to critical areas of the
body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and strikes an occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all vehicle occu­ pants and especially for children. Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling=>&.
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants are correctly
restrained and stay in a correct seating position whenever the
vehicle is being used.
• Always read and heed all WARNINGS and other important
information ~

Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a particular
severity, safety belts are tensioned automatically .
The safety belts are equipped with safety belt pretensioners. The
system is ac tivated by sensors in fron t, side and rear-end collisions of
great severity. This tightens the belt and takes up belt slack~
& in
"Service and disposal of safety belt pretensioner" on
page 189 .
Taking up the slack helps to reduce forward occupant movement
during a collision. .,

& WARNING
Damage to the front passenger seat can prevent the front airbag
from working properly .
• Improper repair or disassembly of the front passenger and
driver seat will prevent the Advanced Airbag Sy stem from func ­
tioning properly.
• Repairs to the front passenger seat must be performed by qual­
ified and properly trained workshop personnel.
• Never remove the front passenger or driver seat from the
vehicle.
• Never remove the uphol stery from the front passenger seat.
• Never disassemble or remove parts from the seat or disconnect
wires from it.
• Never carry sharp objects in your pockets or place them on the
seat. If the weight-sensing mat in the passenger seat is punctured
it cannot work properly.
• Never carry things on your lap or carry objects on the passenger
seat . Such items can increase the weight registered by the weight·
sensing mat and send the wrong information to the airbag control
unit.
& WARNING (c on tinued )
• Never store item s under the front passenger seat . Parts of the
Advanced Airbag System under the pa ssenger seat could be
damaged, p reventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats .
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
se at and prevent the side airbag in the seat backre st from
deploying properly .
• Never use cushions , pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight- sensing mat in the seat from accurately registering the
child restraint or person on the seat and prevent the Advanced
Airbag System from functioning properly.
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel, foam cu shion or something else to properly po sition
the child restraint , make certain that the PASSENGER AIR BAG
OFF light come s on and stays on whenever the child restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on , immediately install child restraint in a rear seating posi­
tion and have the airbag system inspected by your authorized Audi dealer .•

in. WARNING
Us ing the wrong child restraint or an improperly in stalled child
re straint can cause seri ou s personal injury or death in a cra sh.
• Always make su re that the safety belt ret racto r is locked when
installing a child safety sea t. An unlock ed safety belt retractor
cannot hold the child saf ety seat in place during normal driving or
in a cra sh .
• Always bu ckle the ch ild safety seat firmly in place even if a
c hild i s not sitting in it . A loose child safety se at can fly around
during a sudden stop or in a crash.
• Alway s make sure the seat backre st to whi ch the child re straint
is installed is in an upright posit ion and securely latched into place
and cannot fold forward. Otherwise , the seatba ck with the child
safety seat atta ched to it could fly forward in the event of an acci­
dent or other emergen cy situation.

The system operates across the entire speed range in combination
w ith the ABS sys tem. If the A nti-L o ck Brak e System (A BS) mal fun c­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Elect ronic D ifferential Lock (EDL)
and the Anti-Slip Regul ation System (AS R) are in teg rated in the e lec ­
tronic stab ilizat ion program . In addition to the data prov ided by
th ese fun ctions, the ESP control unit re quires addi tional meas ure ­
ment data provided by hig h pe rformance senso rs . The ro tat ional
speed of the vehicle about its vertical axis, veh icle acceleration in the
fore-and-a ft and lateral d irect ions, the brake pressure , a nd the
steerin g ang le are all measured .
Th e d irec tion in whi ch the driver w ishes to tra ve l is d ete rm ined wi th
the a id of the steering a ngle and ve hicle speed and is con tinually
c omp ared wi th the a ctu al b ehavior o f the ve hicl e. If t he two do no t
match, for example, when the vehicle starts hydroplani ng on a wet
roa d, E SP w ill automatica lly bra ke the approp riate whee l to correct
the problem.
Th e ve hicle is t hen stab ilized by the fo rces acting on the whee l during
bra king .
If the ve hicl e is oversteering (the vehicle tu rns too s harp ly
and the rear whee ls slide toward the outside of a curve), the brakes
a re mainly a pplied on the whee l tha t is o n the o uts ide of t he curve. In
the case of a vehicle that is
understeering (the vehicle does not turn
shar ply enough and push es out o f a curve), the b rakes are ap plied as
needed on the whee l th at is on the inside of the curve or additionally
on the ot her wheels . An acoustic s ignal indicates w hen ESP bra ke

Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­
tion of the brake pads throu gh the open ings in the whee l.
If neces­
sary, the whe el may be removed fo r thi s insp ection~

& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission 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 diminish braking efficiency.
• 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 climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working, for example when towing
your vehicle , or because the brake booster has somehow been
damaged, the brake pedal mu st be pressed considerably harder to
make up for the lack of booster assistance. •

Intelligent t echnology L ______________________________________ _
Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort .
The advanced Servotronic® power steering system senses the road
speed and ele ct ronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
veh icle speed .
Power steering will not work if the engine is off . As a resu lt, the
steeri ng wheel will be hard to turn.
T he power steeri ng fluid level is checked du ring the sched uled main ­
tenance services .
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power s teer ing system, provid ing a cons tant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when t urning the s teer ing wheel at low
speeds (for example when park ing) , - more effor t will be required
than us ua l.
• Be aware of the d ifferent than usual steering response and adjust
your stee ring force accord ingly .
• Have the prob lem checked and set r ight by an Audi dealer as soon
as possib le.
[ i ] Tips
• When the e ngine is running, neve r hold the stee ring whee l turned
all the way to the rig ht or to the left for longer than 15 seconds. The
powe r steering pump wi ll overheat the hydra ulic fluid if yo u keep
holding the steering wheel turned all the way . This is likely to damage
t he power s teer ing system . •
If the power steering system s hou ld fa il entirely, or if the engine
is no t ru nning (fo r examp le, while be ing towed), you will st ill be able
to steer the vehicle. However,
considerably more effort will be
req uired to do so .
• If the power steering system should have a leak, or is not func­
tioning prope rly, con tact your au thor ized A udi dealer immedia tely.
• The power steer ing system requires a specia lly formulated
hyd raulic fluid. The power steer ing rese rvoir is the one loc ated
farthest to the rear on the left s ide of the eng ine compartme nt

Dr"ving with your quattro®
With all wheel drive, all four wheels ore driven.
General information
With all wheel d rive, power is d istributed to all four wheels. This
h appens a utomatically depending on your dr iv ing style and t he road
conditions at the time . See also =>

Always read an d fo llow safety precautions =>& .
Winter tires
When driving in the winter, your vehicle with a ll whee l drive has an
adva ntage, even w ith regular t ires . In winter road cond it io ns it may
be advisable to mount winte r tires (or all-seaso n tires) for improved
dr iveability a nd b rak ing: t hese tires mus t be mounted on
all four
wheels . See also => page 307, "Winter ti res" .
Tire chains

Dur ing the break-in period, you sho uld avoid putti ng severe loads on
the brakes. Severe loads include, for example, sud den ha rd brak ing,
i n part icula r a t very high s peed s or, for e xam ple, on moun tain passes.
& WARNING
New brake pads don't have the best stopping power and must be
" broken-in " during the initial 100 to 150 miles (150 to 200 kilo­
meters ) of normal city driving . You can compensate for this by
p ressing the brake pedal more firmly . This also applies later when
new pad s are installed .•
Avoid damaging the vehicle
Whe n yo u are d riving on poor ro ad s, or ove r curbs, steep r amps, etc.,
ma ke ce rtain that low -lying parts such as spoilers and exhaust system
