Sitting correctly and safely

— The electrical capacity is higher than the
threshold stored in the control module
— The electrical capacity is the same as or greater
than the electrical capacity of a typical adult
The passenger's airbag is deactivated if:
— The electrical capacity is lower than the thresh-
old stored in the control module
— The electrical capacity is the same as or less
than the electrical capacity of a typical one-
year-old child in a child safety seat that has
been used for certification in accordance with
FMVSS 208
If the front passenger's airbag is activated, the
PASSENGER AIR BAG ON @ indicator light
will turn on. If the front passenger's airbag is de-
activated, the PASSENGER AIR BAG OFF #;
indicator light will turn on.
The deployment force of the front airbags adapts
based on whether or not the safety belt is used
and the distance between the seat and the steer-
ing wheel/instrument panel. For example, if a
person is too close to the front airbag, the front
airbag will deploy with less force to help reduce
the risk of injury.
Meaning of PASSENGER AIR BAG OFF #4, ON
® indicator light
When the ignition is switched on, the system de-
tects whether the front passenger's seat is occu-
pied. PASSENGER AIR BAG OFF #; ON ®
will turn on for several seconds during this proc-
ess. Then it will indicate whether the front pas-
senger's airbag is activated or deactivated.
— PASSENGER AIR BAG OFF 8%; the front
passenger's airbag is deactivated and will not
deploy in the event of an accident.
— PASSENGER AIR BAG ON @®: the front pas-
senger's airbag is activated and could deploy in
the event of an accident.
If a change to the occupancy status of the front
passenger's seat is detected
PASSENGER AIR BAG OFF #; ON @ will
flash for several seconds and will then display the
status of the front passenger's airbag.

Always make sure the indicator light corresponds
to the occupancy of the front passenger's seat.
— Adults or individuals with a similar stature sit-
ting in the front passenger seat: The front pas-
senger's airbag must be activated.
PASSENGER AIR BAG ON @ must remain
on.
— Individuals with a smaller stature (for exam-
ple, adolescents or smaller adults) sitting in
the front passenger seat: The front passeng-
er's airbag must be activated.
PASSENGER AIR BAG ON ® must remain
on.
— Child in a child safety seat secured on the
front passenger seat: The front passenger's air-
bag must be deactivated.
PASSENGER AIR BAG OFF ®, must remain
on.
— Front passenger seat is not occupied: The front
passenger's airbag must be deactivated.
PASSENGER AIR BAG OFF 3, must remain
on.

Z\ WARNING
— An adult or a person with a small stature
(such as a young person or small adult) seat-
ed on the front passenger's seat will not be
protected by the passenger's airbag in the
event of a collision if the passenger's airbag
is deactivated. This increases the risk of in-
jury and death. Always make sure that
PASSENGER AIR BAG ON @ remains on
while driving. If
PASSENGER AIR BAG ON @ does not
turn on, make sure the front passenger is
sitting correctly in the seat > page 72 and
that there are no objects covering the front
passenger's seat (such as blankets or pil-
lows). If PASSENGER AIR BAG ON @
still does not turn on, the front passenger's
seat must not be used. Drive to an author-
ized Audi dealer or authorized Audi Service
Facility and have the airbag system inspect-
ed.

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.
Dynamic all-wheel steering
Applies to: vehicles with dynamic all-wheel steering
Active corrective steering at the front and rear
axles increases the driving dynamic and driving
stability. At low speeds, the rear wheels are
steered in the opposite direction from the front
wheels to reduce the steering effort needed by
the driver and to reduce the turning radius. Vehi-
cle handling improves. At high speeds, steering
the rear wheels in the same direction as the front
wheels improves the vehicle response and driving
stability. The vehicle reacts quickly and precisely
to the driver's steering movements.
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.

The steering is reinitializing. The steering wheel
will move easily after starting the vehicle. Reiniti-
alization might be necessary if the steering wheel
was moved while the engine was switched off.
The display turns off if the initialization was suc-
cessful.

Z\ WARNING
Do not tow your vehicle if there is a malfunc-
tion in the electronic steering lock because
this increases the risk of an accident.
@ Tips
— If there is a malfunction, the steering wheel
may be crooked when driving straight.
—Ifthe a or a indicator light only stays on
for a short time, you may continue driving.


ALL wheel drive (quattro)
Applies to: vehicles with all wheel drive
The all-wheel drive system distributes the driving
power variably to the front and rear axle to im-
prove the driving characteristics. It works togeth-
er with selective wheel torque control, which can
activate when driving through curves
> page 134.
The all-wheel drive system 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\.

Z\ WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane” if driving at speeds that >

are too high. Unlike front wheel drive
vehicles, the engine RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-
tions to reduce the risk of an accident.
Sy Telamelaielcls
Applies to: vehicles with sport differential

The sport differential distributes the drive power
to the rear axle based on the situation. The goal
is a high level of agility and ability to accelerate
on curves. The vehicle is very responsive to steer-
ing. The settings depend on the selected Audi
drive select* mode.
Messages
Hi Sport differential: malfunction! Please con-
tact Service
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
it} Sport differential: temperature too high.
Please adapt driving style
The transmission temperature has increased sig-
nificantly due to the sporty driving manner. Drive
in a less sporty manner until the temperature re-
turns to the normal range and the indicator light
switches of.

Z\ WARNING
Contact an authorized Audi dealer or author-
ized Audi Service Facility if the sport differen-
tial is faulty or malfunctioning. The repair
must be performed by trained personnel us-
ing the correct oil in order to ensure safety.

Electronic Stabilization
Control
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations, such as if the vehicle is oversteering or
understeering, or if the wheels are spinning. The
brakes are applied or the engine torque is re-
duced in order to stabilize the vehicle.
If the [i indicator light blinks while driving, the
ESC is actively regulating.
If the B&B indicator light turns on, the system has
switched the ESC off. In this case, you can switch
the ignition off and then on to switch the ESC on
again. The indicator light turns off when the sys-
tem is fully functional.
If the B indicator light turns on, ESC was limit-
ed or switched off manually > page 134.
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
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. Depending
on the activated driver assistance systems, the
brake assist system may react with increased sen-
sitivity.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
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. >
