2021 AUDI E-TRON steering wheel

Driving dynamic

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.
Power steering
The ESC can also support vehicle stability
through steering.

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. 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
risk of a collision.
— As the vehicle load increases, especially the
roof load, the vehicle's center of gravity also
increases along with the risk of the vehicle
tipping. To reduce the risk of an accident, al-
ways adapt your driving style to the current
conditions and avoid sudden driving maneu-
vers.

@) 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 motor power.
106
— You may hear noises when the systems de-
scribed are working.
The So button (or #, depending on the model)
for controlling the ESC is located in the center
console, in front of the selector lever. The ESC is
automatically switched on when the ignition is
switched on.
Limiting ESC
In some situations, it may make sense to limit
the stabilizing function of the ESC so that the
wheels can spin, for example to rock a vehicle to
free it when it is stuck or to drive with snow
chains. The ESC can also be limited to provide
more sporty driving characteristics with fewer
stabilizing corrective actions.
—To limit the ESC, press the 0 button briefly.
The B indicator light will turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Depending on the Audi drive select mode that is
selected, one of the following ESC modes will be
selected automatically:
— sport - this mode is designed for driving ona
level surface. It is used in all Audi drive select
modes except offroad.
— offroad - this mode is suited for driving offroad
and is designed for uneven terrain or loose
ground. If you select the offroad Audi drive se-
lect mode, the offroad ESC mode will be auto-
matically used.
Switching off ESC
For a more active control of the vehicle where the
stabilizing functions of the ESC cannot intervene,
the ESC can be switched off.
— To switch off the ESC, press and hold the Sor
button for more than three seconds. The B
and Ea indicator lights turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
lights turn off.

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 130.



@ 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 acceler-
ating 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 by
using another user.
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.
@) 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 126.
— The steering wheel touch recognition may
be limited when you wear gloves. Steering
intervention requests from the steering as-
sist systems may occur more frequently.
— If accessories have been mounted on the
steering wheel, the steering assist systems
may
be limited. The frequency of steering

Fig. 91 Rearview camera coverage area
The assist systems analyze the data from various
sensors and cameras installed in the vehicle. Do
not use any assist systems if there is damage to
the vehicle in an area where sensors and cameras
are located or on the vehicle underbody, or if the
vehicle was involved in a collision. The functional-
ity of the sensors and cameras could be impaired,
or they could malfunction. Have an authorized

Audi dealer or authorized Audi Service Facility
check their function.
Radar sensors
Depending on the vehicle equipment, the area
surrounding the entire vehicle may be detected
> fig. 90 ©.
The wheel sensors on the rear corners of the vehi-
cle are positioned so that the adjacent lanes to
the left and right are detected on roads with a
normal lane width.
Ultrasonic sensors
Depending on vehicle equipment, various areas
may be displayed in the MMI using the ultrasonic
sensors > fig. 90.
The range of the displays depends on the location
of the ultrasonic sensors:
@ Approximately 4 feet (1.20 m)
@® Approximately 3 feet (0.90 m)
@® Approximately 5.2 feet (1.60 m)
© Approximately 3 feet (0.90 m)
© Approximately 3 feet (0.90 m)
The side area ©) is detected and evaluated when
passing. There may have been changes to the sur-
rounding area after switching the ignition off and
on again, after opening the doors, or if the vehi-
cle is left stationary for a period of time. In this
case, the area will appear black until the area has
been detected and evaluated.
Cameras
Use the camera image on the display to assist you
only if it shows a good, clear picture. Keep in
mind that the image in the display is enlarged
and distorted. Under certain circumstances, ob-
jects may appear different and unclear on the dis-
play.
The rearview camera can only detect the area
marked in red > fig. 91. Only this area is dis-
played on the upper display > A\.
LN WARNING
Sensors and cameras have spots in which the
surrounding area cannot be detected. Objects,
animals, and people may only be detected >

Driver assistance

— The system works with the various sensors and
cameras in the vehicle. Vehicles can only be de-
tected once they are within the area and range
covered by the sensors > page 130, fig. 90.
— 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 system does not react to a stationary vehi-
cle in the same lane if it expects that you can
easily drive around the stationary vehicle by
turning the steering wheel.
— The system cannot react to stationary objects,
such as vehicles at the end of a traffic jam, es-
pecially when traveling at high speeds.
— The system 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 system does not respond to people, ani-
mals, or objects that are crossing or approach-
ing from the opposite direction.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.
— The adaptive cruise assist is only an assist
system, and the driver is still responsible for
controlling the vehicle. The driver is espe-
cially 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] button @) when driv-
ing at speeds below 15 mph (20 km/h), the
minimum possible speed that the system
can maintain will be set. If no vehicle is de-
tected ahead of you, the vehicle will acceler-
ate 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.
