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.
All-wheel steering
Applies to: vehicles with all-wheel steering
Additional steering ability at the rear axle im-
proves the driving dynamic and stability. At low
speeds, the rear wheels are steered in the oppo-
site direction from the front wheels to reduce the
turning radius. At high speeds, steering the rear
wheels in the same direction as the front wheels
improves the vehicle response and driving stabili-
ty.
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 rear axle steering may have failed. The vehi-
cle will have a larger turning radius, and the sta-
bility when driving around curves will be compa-
rable to a vehicle without rear axle steering. Drive
carefully to an authorized Audi dealer or author-
ized Audi Service Facility to have the malfunction
corrected.
|e —o| Steering lock: malfunction! Please contact
Service
There is a malfunction in the electronic steering
lock. Drive immediately to an authorized Audi
dealer or authorized Audi Service Facility to have
the malfunction repaired.

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 112.
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.
Sport differential
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
111

Driving dynamic

on curves. The vehicle is very responsive to steer-
ing. The settings depend on the selected Audi
drive select* mode.
Messages
+3] Sport differential: malfunction! Please con-
tact Service
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
3] 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.

ZA 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 oversteering and understeering of
the vehicle, the drive wheels spinning, or the risk
of the vehicle tipping. The brakes are applied or
the engine torque is reduced in order to stabilize
the vehicle.
If the B indicator light blinks while driving, the
ESC is actively regulating.
If the 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.
112
If the B indicator light turns on, ESC was limit-
ed or switched off manually > page 113.
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.
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.

General information
Safety precautions

ZA WARNING
— As the driver, you are always completely re-
sponsible for all driving tasks. The assist
systems cannot replace the driver's atten-
tion. Give your full attention to driving the
vehicle, and be ready to intervene in the
traffic situation at all times.
— Activate the assist systems only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— For the assist systems to be able to react
correctly, the function of the sensors and
cameras must not be restricted. Note the in-
formation on sensors and cameras
=>page 119.

@ Tips
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, vehicle distance, speed,
parking location, wheel placement, etc. The
driver is always responsible for following
the laws that are applicable in the location
where the vehicle is being operated.
— You can cancel a steering or braking inter-
vention by the system, by braking or accel-
erating noticeably, steering, or deactivating
the respective assist system.
— Always check the assist systems settings be-
fore driving. The settings could have been
changed, for example, by other drivers or if
another personal profile was used.

System limitations
ZA\ WARNING
— The use of an assist system cannot over-
come the natural laws of physics. A collision
cannot be prevented in certain circumstan-
ces.
— Warnings, messages, or indicator lights may
not be displayed or initiated on time or cor-
rectly, for example, if vehicles are approach-
ing very fast.
— Corrective interventions by the assist sys-
tems, such as steering or braking interven-
tions, may not be sufficient or they may not
occur. Always be ready to intervene.
G) Tips
— Due to the system limitations when detect-
ing the surrounding area, the systems may
warn or intervene unexpectedly or too late
in certain situations. The assist systems may
also interpret a driving maneuver incorrectly
and then warn the driver unexpectedly.
— The systems may not function as expected
in unusual driving situations, such as driving
offroad, on unpaved roads, on loose ground,
on inclines, or on grooves in the road.
— The systems may not function correctly in
unclear traffic situations, such as turning
lanes, exit ramps, construction zones, rises
or dips that obstruct visibility, intersections,
toll stations, or city traffic.
— The detection of the surrounding area can
be limited, for example by vehicles driving
ahead or by rain, snow, heavy spray, or light
shining into the camera.
—In trailer mode, some assist systems may be
limited, may not react as usual, or may be
unavailable. Please refer to the instructions
for towing a trailer located in > page 115.
— If accessories have been mounted on the
steering wheel, the ability for the steering
systems to react may be limited.

brakes. You can override the system by pressing
the accelerator pedal briefly.
— The adaptive cruise assist works with the vari-
ous sensors and cameras in the vehicle.
Vehicles can only be detected once they are
within the area and range covered by the sen-
sors > page 119, fig. 98.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate unexpectedly.
— The adaptive cruise assist does not react to a
stationary vehicle in the same lane if the sys-
tem expects that you can easily drive aroun d
the stationary vehicle by turning the steering
wheel.
— The adaptive cruise assist may not react to sta-
tionary obstacles, such as the end of a traffic
jam, especially at high speeds.
— The adaptive cruise assist has a limited ability
to detect vehicles that are a short distance
ahead, off to the side of your vehicle, or moving
into your lane.
— Objects that are difficult to detect, such as mo-
torcycles, vehicles with high ground clearance,
or vehicles with an overhanging load, may be
detected late or not detected at all.
— The adaptive cruise assist does not respond to
people, animals, or objects that are crossin
approaching from the opposite direction.
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 118.

responsible for controlling the vehicle. The
driver is especially responsible for braking,
steering, starting to drive, and controlling
the speed and the distance from other
vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.
— If you press the [SET|2) button when driving
at speeds below 20 mph (30 km/h), then 20
mph (30 km/h) will be set because that is
the minimum speed that can be set. If no
vehicle is detected ahead of you, the vehicle
will accelerate up to that speed.


@ Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— If you switch the ignition or the adaptive
cruise assist off, the stored speed is erased
for safety reasons.
— When the adaptive cruise assist is switched
on, the ESC and the ASR are switched on au-
tomatically.
— The system cannot be switched off or it may
be interrupted if the road exceeds the maxi-
mum possible grade for safe operation.

Lane departure warning
(erreur laced)
Applies to: vehicles with lane departure warning
The lane departure warning can detect lane
marker lines within the limits of the system. If
you are approaching a detected lane marker and
it appears likely that you will leave the lane, the
system can warn you with corrective steering and
a steering wheel vibration, if necessary.
The system functions in the speed range of ap-
proximately 40 mph - 155 mph (65 km/h -
250 km/h).
Applies to: vehicles with lane departure warning
and without side assist: Even if the system is
ready, it will not warn you if you activate a turn
signal before crossing the lane marker line. In
this case, it assumes that you are changing lanes
intentionally.
Applies to: vehicles with lane departure warning
in combination with side assist: If the turn signal
is activated, the lane departure warning is ready,
and a lane change has been classified as critical
by the lane departure warning due to vehicles
traveling beside you or due to approaching
vehicles, then a noticeable corrective steering
movement will occur briefly before exiting the
lane. This will attempt to keep your vehicle in the
lane.
