Intelligent Technology
Electronic stabilization
control (ESC)
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations such as the vehicle oversteering and un-
dersteering or the wheels are spinning. The
brakes are applied or the engine torque is re-
duced in order to stabilize the vehicle. When the
ESC engages, the B indicator light blinks in the
instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle.
Brake assist system
The brake assist system can decrease braking dis-
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit-
uations. You must press and hold the brake pedal
until the dangerous situation is over.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the drive wheels
begin spinning and adapts the power to the road
conditions. This makes it easier to start, acceler-
ate and drive up hills.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
86
EDL will switch on again automatically when con-
ditions have returned to normal.
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision above a certain ve-
hicle speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal
—The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

ZA WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre-
vent collisions - there is still a risk of acci-
dents!

@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.
— Before driving on long stretches with steep
hills, reduce the vehicle speed and shift to a
lower gear to use the engine braking effect.
This reduces the load on the brakes. If you
need to brake additionally, brake in intervals
and not continuously.
@) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.
— Also refer to the information about brake
fluid > page 235.
Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.
a Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-
cation as soon as possible. Do not continue driv-
ing. See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
a Steering: malfunction! You can continue
driving
There is a malfunction. Steering may be more dif-
ficult or more sensitive. Adapt your driving style.
Have the steering system checked immediately
by an authorized Audi dealer or authorized Audi
Service Facility. Please note that the red indicator
light may turn on after restarting the engine. Do
not continue driving if it does.
G@) Tips
If the 12 or al indicator light only stays on
for a short time, you may continue driving.
ALL wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all wheel drive, the driving power is divided be-
tween all four wheels. This happens automatical-
ly depending on your driving behavior as well as
the current road conditions. Also see > page 86,
Electronic stabilization control (ESC).
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre-
cautions > A\.
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con-
ditions. However, in winter we recommend using
winter or all season tires on all four wheels, be-
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
=> page 255, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid using tires with different tread depths
=> page 247, New tires or wheels.

Safe driving

> 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.

Z\ WARNING
Impaired driving safety increases the risk of
serious personal injury and death whenever a
vehicle is being used.

> Grasp the top of the steering wheel with your
elbow(s) slightly bent.
> Fasten and wear safety belts correctly
=>page 185.
> Always keep both feet in the footwell so that
you
are in control of the vehicle at all times.
For detailed information on how to adjust the
driver's seat, see > page 46, Front seats.


Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving.

BFV-0183


Fig. 145 Correct seating position
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 > A\.
> 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 dis-
tance of at least 10 in (25 cm) between the
steering wheel and your breast bone > fig. 145.
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.
178
Z\ WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously injured
by an airbag as it unfolds. To help reduce the
risk of serious personal injury:
— Always adjust the driver's seat and the
steering wheel so that there are at least
10 in (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 in
(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
properly and make sure that all passengers

are properly restrained.

Safety belts

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo-
ple riding in vehicles.

BFV-0184





BFV-0185



(2,000 lbs, or 1,000 kg) or more. At higher
speeds, these forces are even greater.
People who do not use safety belts are also not
attached to their vehicle. In a frontal collision
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 wearing
liam llieya
In crashes unbelted occupants cannot stop
themselves from flying forward and being in-
jured or killed. Always wear your safety belts!

Fig. 148 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 weight, the more energy
that has to be “absorbed” in the crash.
Vehicle speed is the most significant factor. If the
speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 times!
Because the passengers of this vehicle are not us-
ing
safety belts > fig. 147, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall > fig. 148.
The same principles apply to people sitting in a
vehicle that is involved in a frontal collision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton

Fig. 149 A driver not wearing a safety belt is violently
thrown forward
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 violently into the steering wheel, in-
strument panel, windshield, or whatever else is
in the way > fig. 149. This impact with the vehi-
cle interior has all the energy they had just before
the crash.
Never rely on airbags alone for protection. Even
when they deploy, airbags provide only additional
protection. Airbags are not supposed to deploy in
all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, in-
cluding the driver, must wear safety belts cor-
rectly in order to minimize the risk of severe in-
jury or death in a crash.
Remember too, that airbags will deploy only once
and that your safety belts are always there to
