Adaptive Air Suspension and
Damping
A pplies to vehicles: wi th Adap tive Air Suspens ion
Description
Adaptive Air Suspension and damping can be regulated
and they adapt automatically to a request from the driver
and the driving situation at the time.
Adaptive Air Suspension is an electronically controlled springing
and damping system . This chassis system makes it easier on the
driver by adapting to the particular situation through imperceptible
control processes.
The
Adaptive Air Suspension component regulates ground clear ­
ance depending on vehicle speed, load condition and driver input.
When the system is in automatic mode, accelerating to a speed above a predetermined limit will make the vehicle lower itself. On
the other hand, driving more slowly results in the vehicle raising again at specific speeds.
The
damping component provides individual control of the
damping forces. For example, with damping characteristics set to
provide greater comfort, damping is set somewhat harder for a brief
period only as required, for example, when going around a curve or
over rough road surfaces as well as when braking.
Settings
Adaptive Air Suspension provides the driver with the opportunity to
set the chassis characteristics also to their individual preference.
With the driving modes
standard, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty .
In addition,
lift provides a fourth mode which can be selecting for
driving over poor stretches of road :::::,
page 185, "Chassis controls". The modes are set in
MMI:::::,
page 185.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuations or changes in load.
0 Note
• Whenever you park your vehicle, always make sure there is
adequate clearance above and below the vehicle. The height of the parked vehicle can change as the result of temperature fluctuations,
changes in load condition and changes in the driving mode (ground
clearance!.
• If the vehicle is being transported (e.g. by tow truck, train, ship,
etc.) , mount the tie -down chains/cables over the running surface
(circumference) of the tires . Never secure the vehicle by the axle, the
suspension struts or the front or rear towline eye. For technical
reasons, the pressure in the suspension struts may change during
the transport, which could result in the vehicle no longer being
secured properly.
• To prevent damage to the vehicle underbody, remember that
your vehicle is not an off-road vehicle, even in the "lift" mode. The
ground clearance is insufficient for this type of operation.
• If you are going to tow a trailer, you must activate the trailer oper­
ation mode :::::,
page 186.
[ i] Tips
Before you raising your vehicle using the vehicle jack (for example,
when changing a flat tire) you must activate the jacking mode
=> page 186. •

Four different driving modes can be set by the driver.
The automatic contro l processes are speed -and time -dependent.
For example, it is not possib le to raise the suspension to the lift
mode above certain speeds.

Se lect the automatic mode i f you p refer suspension and damping
settings emphasizing comfort .
• Low ering : When a speed of about 75 mph (120 km/h) is exceeded
for more than 30 seconds, the vehicle is automatically lowered by about 0.6 inch (15 mm) to the dynamic level which is more suitable
for highway speeds. Road holding is optimized as a result of the lower center of gravity and fuel consumption is reduced as a result
of reduced wind res istance.
• Rais ing : The vehicle is automatically raised again if the speed
falls below about 44 mph (70 km/h) for a period of 2 minutes . The
vehic le is raised immediate ly when speed falls below about 22 mph
(35 km/h).
s ta nd ard
Select the standard mode if you desire a suspension setting with a
special emphasis on comfort. In the standard mode there is
no
lowering of the suspension. Even a t high speeds, the vehicle stays
at the same level. Damping characteristics with a decided emphasis
on comfort are selected in this mode.

remind you of the reduced ground clearance .
If y ou switch off the engine wh ile the ve hicle is in the dynamic mode
and then switch on the ignition once again, the
c.::i warning light
wi ll also come on again f or a few seconds as a reminder .
lift
Select the lift mode when you have to travel over poor sect ions of
road (e .g. trails). In the lift mode, the vehic le is raised by 0.6 inch (15
m m) compared to norma l leve l while it is stil l stationary and
damping characteristics are adjusted to emphasize comfort .
The lift mode can be activated only at speeds below 50 mp h (80
km/h) . When a speed of about 62 mph (100 km/h) is exceeded, the
system automatical ly leaves lift mode and the mode set previously
(standard, automat ic, dynam ic) is activated aga in. •

-Airbag system ----=--a.---------------------------------------
& WARN ING (continued )
• Always make sure that the side airbag can inflate without inter­
fe rence :
- Never install seat covers or replacement upholstery over the
front seatback s that have not been spe cifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags inflate .
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi ­
ately by an authorized Audi dealer .
• The airbag system can be activated only once. After an airbag
ha s inflated , it must be replaced by an authorized Audi de aler or
qualified technician who has the technical information , training
and special equipment necessary .
• The airbag system can be deployed only once. After an airbag
has been deployed , it must be repla ced with new repla cement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• For safety reasons in severe accidents , the alternator and
starter are separated from the vehicle battery with a pyrotechn ic
circuit interrupter.
-Work on the pyrotechni c circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehi cle or the circuit inte rrupter is scrapped , all appli ­
cable safety precautions must be followed.

Other things that can affect Advanced Airbag
performance
Changing the vehic le 's suspension system can change the way that
t h e Adva nced Ai rbag Syste m performs in a c rash. Fo r example,
using tire -rim combinations not approved by Audi, lowering the
ve hicle, c hang ing the s tif fne ss of the su spe nsio n, in cl ud in g th e
springs, suspens ion struts, shoc k absorbers etc. can change the
f o rce s tha t are m eas ure d b y the air bag senso rs and se nt to the e lec ­
tronic control unit. Some suspension changes can, for example,
increa se the fo rce levels measured by the senso rs and ma ke the
airbag system dep loy in crashes in which it wou ld not deploy if the
changes had not been made . Othe r kinds of changes may reduce
t h e force lev els measured by the sensors and preve nt the airbag
from dep loying when it sho uld.
T he s ensors i n the safet y be lt buc kle for the driver a nd fr ont
passenger seat tell the e lectronic contro l modu le if the safety belt is
l a tc h ed or not. If the sa fety belt is b eing use d, th e front airbag wi ll
deploy at a slightly higher rate of v ehic le dece leration than if the
safety be lt is n ot be ing use d. T herefo re, i n a partic ular collision, it i s
possible that an air bag wi ll not deploy at a seating position where
the safety be lt i s being used but wi ll inflate at the position whe re the
sa fety be lt is not bei ng used. It is important tha t noth ing i nte rfer e
with the safety belt buckles so that the sensors can send the correct
i nfo rmati on about saf ety belt use to the e lectr onic co ntrol unit. .,.

& WARNING
Changing the vehicle's suspension including u se of unapproved
tire -rim combinations can change Advan ced Airbag performance
and in crease the risk of serious per sonal injury in a crash .
• Never in stall su spension components that do not have the
same pe rformance character istics as the components or iginally
installed on your vehicle.
• Never use t ire-r im combinations that have not b een approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
c onsole can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Adv anced Airbag System from working properly .
• Alway s make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed .
