Sitting correctly and safely


— Push the lever upward firmly so that the
steering wheel position does not change un-
intentionally while driving, which would in-

crease the risk of an accident.

Head restraints
General information
Applies to: vehicles with adjustable head restraints

B4G-0454



Fig. 60 Correctly adjusted head restraints
Make sure that:
— The upper edge of the head restraint is as even
as possible with the top of your head
— The head restraint is as close as possible to the
back of the head
— The head restraints in any occupied rear seats
are all the way up

Z\ WARNING
— There is one head restraint for each seating
position. All vehicle occupants must adjust
the head restraint correctly before every
trip. Having head restraints that are not ad-
justed correctly or not installed in the vehi-
cle increases the risk of a neck injury during
sudden or unexpected driving or braking
maneuvers or in a collision.
— Only remove the rear seat head restraints if
it is necessary to install a child safety seat
=> page 72. Stow the removed head re-
straints securely, for example in the luggage
compartment. Reinstall the head restraints
immediately once the child safety seat has
been removed. Driving without head re-
straints increases the risk of serious neck in-
juries.

Sitting correctly and safely

occupant detection sensor measures the electri-
cal capacity on the front passenger’s seat. The
passenger's airbag is activated or deactivated de-
pending on the electrical capacity that is meas-
ured.
The passenger's airbag is activated if:
— 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 3; 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.
— An adult or individual of similar size in the
front passenger's seat: the front passenger's
airbag must be activated, so
PASSENGER AIR BAG ON ® must remain
on.
— An individual of smaller size (for example, an
adolescent or small adult) in the front pas-
senger's seat: the front passenger's airbag
must be activated, so
PASSENGER AIR BAG ON @ must remain
on.
— Child in a child safety seat on the front pas-
senger's seat: the front passenger's airbag
must be deactivated, so
PASSENGER AIR BAG OFF #%; must remain
on.
— Front passenger's seat not occupied: the front
passenger's airbag must be deactivated, so
PASSENGER AIR BAG OFF ®, must remain
on.

ZA\ 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 59 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

Driving dynamic

suspension will adapt to the driving conditions
and 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.
Hi Suspension: malfunction! You can continue
driving


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.
Dynamic steering
Applies
to: vehicles with dynamic steering
The driving dynamic and driving stability are in-
creased by the steering ratio based on the speed.
At reduced speeds, steering is direct in order to
provide agile steering behavior and keep the
steering effort as minimal as possible when the
driver is maneuvering the vehicle. This sets the
steering to be less sensitive at higher speeds in
order to provide improved vehicle control.
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 in the steering system.
Steering may be more difficult or more sensitive.
Adapt your driving style. Have the steering sys-
tem checked immediately by an authorized Audi
dealer or authorized Audi Service Facility. Please
note that the red indicator light may turn on af-
ter restarting the engine. Do not continue driving
if it does.
Dynamic steering: correcting steering wheel
Position
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.
@) Tips
—If there is a malfunction, the steering wheel
may be crooked when driving straight.
—Ifthe a or Ee indicator light only stays on
for a short time, you may continue driving.

sensors and cameras installed in the vehicle. Do
not use any assist systems if there is damage in
there area of the sensors and cameras or on the
vehicle underbody. Damage can impair the func-
tion of the sensors and cameras or cause mal-
functions. Have an authorized Audi dealer or au-
thorized Audi Service Facility check their func-
tion.
Radar sensors
Depending on the vehicle equipment, the area
surrounding the entire vehicle may be detected
> fig. 104 ©.
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. 104.
The range of the displays depends on the location
of the ultrasonic sensors:

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. 105. Only this area is dis-
played on the center display. > A\.

Driver assistance

Steering intervention request
If no steering activity is detected or the steering
power from the system is not sufficient, the driv-
er steering intervention request will alert the
driver using audio and visual signals. Take over
the steering and keep your hands on the steering
wheel so that you will be ready to steer at any
time. The system may no longer be ready to pro-
vide warnings after a short time, and it will only
become active again later.
If the driver takes over steering, active lane assist
will be switched off.
Behavior when a turn signal is active
Applies to: vehicles with side assist: The system
will not warn you if you activate a turn signal be-
fore crossing the lane marker line. In this case, it
assumes that you are changing lanes intentional-
ly.
Applies to: vehicles with side assist: If the side
assist system classifies a lane change as critical
due to other vehicles traveling with your vehicle
or approaching your vehicle when your turn sig-
nal is activated, there will be a noticeable steer-
ing correction shortly before your vehicle leaves
the lane. This will attempt to keep your vehicle in
the lane.

ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
— Corrective steering may not occur at all in
certain situations, such as during heavy
braking. Always be ready to intervene.

G) 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

YD In certain countries

adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— The system does not provide any corrective
steering or steering wheel vibrations if it de-
tects that you are passing another vehicle.
— The image in the Driver assistance display
only appears if it was opened in the on-
board computer = page 15.
