Suspension
CET NRC Ld
Applies to: vehicles with suspension control
The adaptive dampers are an electronically-con-
trolled damping system. The firmness of the sus-
pension will adapt to the driving conditions and
the driving situation. The settings are dependent
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

Z\ 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.

EET
| 8 | 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
92
speed. The settings are dependent on the select-
ed 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-
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.
|2—| Steering: malfunction! Please stop vehicle
There is a malfunction in the electronic steering
lock. You cannot turn the ignition on. Do not tow
your vehicle because it cannot be steered. See an
authorized Audi dealer or authorized Audi Service
Facility for assistance.
a Steering: malfunction! You can continue
driving
There is a malfunction. Steering may be more dif-
ficult or more sensitive. Adapt your driving style.
Have the steering system checked immediately
by an authorized Audi dealer or authorized Audi
Service Facility. Please note that the red indicator
light may turn on after restarting the engine. Do
not continue driving if it does.

Airbag system


entered in your Audi Warranty & Mainte-
nance booklet under AIRBAG REPLACEMENT
RECORD.
— Applies to plug-in hybrid* vehicles: In the
event of a collision where the airbags de-
ploy, the electrical connection to the high
voltage battery is automatically disconnect-
ed. This prevents a short circuit.
Other things that can affect Advanced
ONY em ace lie
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit. Some suspension changes
can, for example, increase the force levels meas-
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy-
ing when it should.

ZX, WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in-
crease the risk of serious personal injury ina
crash.
— Never install suspension components that
do not have the same performance charac-
teristics as the components originally instal-
led on your vehicle.
— Never use tire-rim combinations that have
not been approved by Audi.


Knee airbags
Pregl) aCe ola ACLs eh)
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen-
tal protection to properly restrained front seat
occupants.

Fig. 219 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel > fig. 219, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec-
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
=> page 263, More important things to know
about front airbags.
In addition to their normal safety function, safe-
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu-
pant restraint system in your vehicle. Always re-
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should al-
ways wear your safety belt, not just because the
law requires you to do so > page 245, General
notes.
