N .... 0 0 :c ' -New brake pads do not achieve their fu ll
brak ing effect during the first 250 mi
(400 km). They must be "broken in" first.
However, you can compensate for the
sl ightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy brak­
ing dur ing the b reak-in per iod.
- Certa in weather and operat ing cond it ions
such as dr iving t hrough water, d riving in
heavy ra in or d riving after washing your ve­
hicle ca n impair the effectiveness of the
bra kes . In the w inter, ice may b uild up on
the brake pads, rotors and drums . Check
these components by braking carefu lly. Ap­
plying the brakes carefu lly several times
dr ies the brakes and removes ice bu ild-up.
- The effic iency of the brakes can also be im­
paired by driving for long st retches on roads
cove red w ith salt without using the b rakes.
Yo u can remove sa lt deposits from the
bra ke rotors and pads by caref ully applyi ng
the brakes severa l t imes .
- If the front spoiler is damaged or you install
another spoiler, ma ke sure the front wheel
bra kes are vent ilated prope rly. O therwise,
the br ake system could overheat, wh ic h re­
duces the ir effectiveness.
- Failure of a brake circui t impai rs b raking
perfo rmance, whi ch incre ases bra king dis­
tance . Avoi d driving the vehicle and have it
towed it to the nearest author ized Audi
dealer or authorized A udi Se rvice Facility .
- If the bra ke booster is not wor king, you will
have to press m uch ha rder on the bra ke
peda l to compensate for the lack of the
booster.
(D Note
- Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
necessary. This causes the brakes to over­
heat and inc reases braking d istance and
causes wear.
- Before driving downh ill a long distance on a
steep h ill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes . If Intellig
ent Technology
you need to bra ke ad ditiona lly, bra ke in in­
terva ls and not continuous ly .
(D Tips
- If the brake boos ter is not wor king, you
must press the brake peda l with much more
force than normal.
- If you retrof it your vehicle with a front spo il­
er, wheel covers or simi lar items, make su re
that the air f low to the front wheels is not
inter rupted. Otherwise the b rake system
can become too hot.

All wheel drive (quattro)
In all wheel drive, all four wheels are powered .
General information
In a ll wheel drive, the driving power is divided be­
tween a ll four wheels . T his happens automatical ­
ly depending on your driving behavior as well as
t he current road cond itions. Also see
c> page 126, Electronic Stabilization Control
(ESC) .
With the sport differential*, power distri­
bution to the rear whee ls is variable and can be
ad ju sted using the dr ive select
c> page 110.
The all wheel drive concept is designed for h igh
eng ine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under norma l dr iv ing condit ions and on
snow a nd ice. Always read and fo llow safety pre­
cautions
c> .&. .
Winter tires
By us ing all w heel d rive , yo ur vehicle has good
forward mot ion w ith standa rd t ires in winter con­
d itions . However, in winter we recommend us ing
w in ter o r all season t ires o n all fo ur wheels, be ­
cause this will improve the b raking effect .
Snow chains
If there are snow chai n laws, snow chains must
a lso be used on vehicles with all w heel d rive
c> page 298, Snow chains .
130 Replacing tires
Fo
r vehicles wi th a ll wheel d rive, o nly wheels with
the same ro ll ing circ umfe rence sho uld be used .
Avo id using tires with different tread depths
c> page 290, New tires or wheels .
Offroad vehicle?
You r A udi is not an off road vehicle -there is not
enough ground clearance. For th is reason, avoid
difficult terrain .
A WARNING
- Also, in ve hicles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel d rive vehi­
cle. Do not be tempted to accelerate to a high speed when the road is s lippery, be ­
c a use th is i ncreases the r is k of an accident.
- Note that on wet st reets, the front wheels
c a n " hydroplane " if driv ing at speed s tha t
are too high. Unlike front wheel drive
vehicles, t he engine does not rev higher sud ­
de nly when the vehicle begins hydroplan ing.
For this reason, adapt yo ur speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is no t drive n for a long t ime, the veh icle bat­
te ry is drained by equ ipment (fo r example, the
i mmob ilizer). In certa in circ umstances, there
could may not be enough energy to start the en ­
gine.

Driving safety
• Sit properly in your seat and make sure that
your passengers do the same
c:> page 54, Seats
and storage.
• Fasten your safety belt and wear it properly . Al ­
so instruct your passengers to fasten their safe­
ty belts properly
c:> page 218 .
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle, the driver as well as the driver 's abili­
ty to concentrate on the road without being dis ­
tracted .
The driver is responsible for the safety of the ve­
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road
c:> Li').. Therefore :
• Do not let yourself be distracted by passengers
or by using a cellular telephone .
• NEVER drive when your driving ability is im­
paired (by medications, alcohol, drugs, etc.).
• Observe all traffic laws, rules of the road and
speed limits and plain common sense.
• ALWAYS adjust your speed to road, traffic and
weather conditions.
• Take frequent breaks on long trips. Do not drive
for more than two hours at a stretch.
• Do NOT drive when you are tired, under pres­
sure or when you are stressed.
A WARNING
Impaired driving safety increases the risk of
ser ious personal injury and death whenever a
vehicle is being used.

Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving.
Fig. 218 Correct seating posit ion
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver's seat to the following position:
• Adjust the driver's seat so that you can easily
push the pedals all the way to the floor while
keeping your knee(s) slightly bent
c:> .&_ .
• Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact with it when you drive.
• Adjust the steering wheel so that there is a d is­
tance of at least 10 inches (25 cm) between the
steering wheel and your breast bone
r::!) fig. 218.
If not possible, see your authorized Audi deal­
ership about adaptive equipment.
• Adjust the steering wheel so that the steering
wheel and airbag cover points at your chest and
not at your face.
• Grasp the top of the steering wheel with your
elbow(s) slightly bent.
• Adjust the head restraint so the upper edge is
as even as possible with the top of your head .
If
that is not possible, try to adjust the head re­
straint so that it is as close to this position as
possible.
• Fasten and wear safety belts correctly
c:>poge 221.
• Always keep both feet in the footwell so that
you are in control of the vehicle at all t imes .

page 54.
A WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in­
jured by an airbag as it unfolds. To help re­
duce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least 10 inches (25 cm) between your breastbone
and the steering wheel.
- Always adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and the
lower part of the instrument panel.
- Always hold the steering wheel on the out­
side of the steering wheel rim with your
hands at the 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal in­
jury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o 'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Holding
the steering wheel the wrong way can cause
serious injuries to the hands, arms and head if the driver's airbag inflates.
- Pointing the steering wheel toward your face decreases the ability of the supplemen­
tal driver's airbag to protect you in a colli­
sion.
- Always sit in an upright position and never
lean against or place any part of your body
too close to the area where the airbags are
located.
- Before driving, always adjust the front seats and head restraints properly and make sure
that all passengers are properly restrained.
- Never adjust the seats while the vehicle is
moving . Your seat may move unexpectedly
and you could lose control of the vehicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are
tilted back, the greater the risk of injury due
to incorrect positioning of the safety belt
and improper seating position.
Driving safety
- Children must always ride in child seats
¢
page 248. Special precautions apply
when installing a child seat on the front passenger seat¢
page 226.
Proper seating position for the front
passenger
T he proper front passenger seating position is
important for safe, relaxed driving .
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the seat for the front passenger
to the following position :
... Adjust the angle of the seatback so that it is in
an upright position and your back comes in full
contact with it whenever the vehicle is moving.
... Adjust the head restraint so the upper edge is
as even as possible with the top of your head.
If
that is not possible, try to adjust the head re­
straint so that it is as close to this position as
possible ¢
page 210.
... Keep both feet flat on the floor in front of the
front passenger seat.
... Fasten and wear safety belts correctly
¢page 221.
For detailed information on how to adjust the
front passenger's seat, see ¢
page 54.
A WARNING
-Front seat passengers who are unbelted, out
of position or too close to the airbag can be
seriously injured or killed by the airbag as it
unfolds . To help reduce the risk of serious
personal injury:
- Passengers must always sit in an upright po­
sition and never lean against or place any part of their body too close to the area
where the airbags are located.
- Passengers who are unbelted, out of posi­
tion or too close to the airbag can be seri­
ously injured by an airbag as it unfolds with
great force in the blink of an eye . ..,

Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 221 Unbelted occupants in a vehicle heading for a wall
Fig. 222 The vehicle crashes into the wall
The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­ ies with vehicle speed and body weight. Engi­
neers call this energy "kinetic energy."
The higher the speed of the vehicle and the greater the vehicle's we ight, the more energy
that has to be "absorbed" in the crash.
Veh icle speed is the most significant factor. If
the speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 t imes!
Because the passengers of this vehicle are not us­
ing safety belts
¢fig. 221, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall¢
fig. 222 .
Safety belts
The same p rinciples apply to people sitting in a
vehicle that is invo lved in a fronta l co llision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
(2,000 lbs, or 1,000 kg) or more. At greater
speeds, these forces are even higher.
People who do not use safety belts are a lso not
attached to the ir vehicle. In a frontal collis ion
they will also keep moving forward at the speed
their vehicle was travelling just before the crash .
Of course, the laws of physics don't just apply to
frontal collisions, they determine what happens in all kinds of accidents and collisions .
What happens to occupants not wea ring
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 223 A dr iver not wearing a safety belt is violently
thrown forward
Fig . 224 A rear passe nger not wearing a safety belt will fly
forwa rd and strike the driver
Unbelted occupants are not able to resist the tre­
mendous forces of impact by holding tight or
bracing themselves . Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam v iolently into the steering wheel,
