the driving situation. The settings depend on the
selected Audi drive select* mode.
Ground clearance
The vehicle height and clearance can be influ-
enced by the following factors:
— Change in temperature
— Change in load
ZA\ WARNING
To reduce the risk of injury, make sure no one
gets pinched when the vehicle level is chang-
ing, for example when cleaning the under-
body or the wheel housings.
©) Note
Always make sure there is enough clearance
above and below the vehicle. This is especially
important for entrances with height restric-
tions, for example, before driving into under-
ground garages. You could also scrape the
ground when driving over the edges of curbs
or on steep ramps, which could damage your
vehicle.

There is a malfunction. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance.
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.
Progressive steering
Applies to: vehicles with progressive steering
The driving dynamic and driving stability are in-
creased by the steering ratio based on the steer-
98
ing wheel angle. The steering is very direct when
the steering wheel angle is sharp, and indirect
when the angle is low. This enables comfortable
maneuvering and a precise steering response at
higher driving speeds.
Messages
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.

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 100.
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\.
ZA 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.

it} All wheel drive: too hot. Please adapt driv-
ing style. See owner’s manual
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.
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 Eq indicator light blinks while driving, the
ESC is actively regulating.
If the BA 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 100.
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 >
99
Page 102 of 278
Driving dynamic
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.
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, 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, or
— 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
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. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the
ZA WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
100
risk of a collision.
@) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead toa
reduction in engine power.
— You may hear noises when the systems de-
scribed are working.
The So button is located above the selector lev-
er in the center console.
The ESC is automatically switched on when the
ignition is switched on. It may make sense in
some situations to limit the ESC so that the
wheels can spin:
— Rocking the vehicle to free it when it is stuck
— Driving in deep snow, on unpaved ground, or
with snow chains
— Driving downhill while braking on loose ground
— Driving with axle articulation

Assist systems
@) Tips
— The coverage areas of the sensors > fig. 85
are diagrams and do not represent a true-
to-scale image of the sensor ranges. The ra-
dar sensors are designed to detect the left
and right adjacent lanes when the road
lanes are the normal width.
— The sensors and the areas around them
must not be obstructed because this can im-
pair the function of the systems that de-
pend on them. Make sure that the sensors
are free of snow, ice, and other deposits. Do
not use any accessories, stickers, or other
objects that extend into the range of the
sensors.
— Do not use a license plate bracket different
from the one installed by the factory in the
front of the vehicle, because it may impair
the function of some systems.
— The sensors can shift from an accident,
manual force, impacts, or from damage to
the radiator grill, bumper, wheel housing,
or underbody. Do not continue using the as-
sistance systems if the sensors have shifted,
because this is unsafe. Have an authorized
Audi dealer or authorized Audi Service Fa-
cility check their function.
— The function of the sensors may be limited
when light and visibility conditions are poor,
for example when driving into a tunnel,
when there is glare, or when there are re-
flective objects.
— External ultrasonic sensors, such as those in
other vehicles, can interfere with the sen-
sors.
—The side area ©)* is detected and evaluated
when passing. There may have been
changes to the surrounding area after
switching the ignition off and on again, af-
ter opening the doors, or if the vehicle is left
stationary for a period of time. In this case,
the area will appear black until the area has
been detected and evaluated.

Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.
ZA\ WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
() Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and reduces the load placed on the
brakes.

Adaptive speed/cruise
assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
The adaptive speed/cruise assist (called only
adaptive cruise assist in the vehicle display and in
the rest of the Owner's Manual) consists of a
speed and distance control system. It assists the
driver by both regulating the speed and main-
taining the set distance to the vehicle driving
ahead, within the limits of the system. If the sys-
tem detects a vehicle driving ahead, the adaptive
cruise assist can brake and accelerate your vehi-
cle within the limits of the system. On open roads
with no traffic, it functions like a cruise control
system. The stored speed is maintained. When
approaching a vehicle driving ahead, the adaptive
cruise assist automatically brakes to match that
vehicle's speed and then maintains the set dis-
tance as much as possible. As soon as the system
does not detect a vehicle driving ahead, adaptive
cruise assist accelerates up to the set speed.
Page 118 of 278
Driver assistance
responsible for controlling the vehicle. The
driver is especially responsible for braking,
starting to drive, controlling the speed, and
maintaining the distance to 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.
ZA WARNING
If you press the SETK2) 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 ac-
celerate up to that speed.
@ Tips
— Always keep your hands on the steering
wheel. 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 if the
road exceeds the maximum possible grade
for safe operation.
— If you signal to pass and the adaptive cruise
assist suggests a passing maneuver, the
adaptive cruise assist will accelerate just be-
fore changing lanes to shorten the distance
to the vehicle driving ahead.

Setting the distance
Applies to: vehicles with adaptive cruise assist
B4M-0234
Fig. 97 Operating lever: setting the distance
If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher

indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise assist brakes to the set speed and
then maintains the set distance. If the vehicle
driving ahead accelerates, then the adaptive
cruise assist will also accelerate up to the speed
that you have set.
The following distances can be set:
