Adaptive Air Suspension
Adaptive Air Suspension and
Damping
Description
Adaptive Air Suspension and damping can be regulated and they adapt automatically to a request from the
driver and the drivin g situati on at the time.
Adaptive Air Suspens ion is an e lectron ically controlled springing and
damping system. This chass is system makes it eas ie r on the d river by
adapting to the particular situation t hrough imperceptible contro l
processes.
T he
Adapt ive Air Su spen sion component regu lates ground clea rance
depending on vehicle speed, load condition and driver input. Acce le r·
a ting to a speed above a predetermined limi t will make the vehicle
lower itself. On the other hand, driving more slow ly results in the
vehicle raising aga in at spe cific speeds .
Th e
damping component provides individua l contro l of the damping
forces. For example, with damp ing characte rist ics set to provide
greater comfort, damp ing is set som ewhat harder for a br ief period
only as req uired, for example, whe n going around a curve or over
roug h road surfaces as we ll as when bra king.
Settings
Adaptive Air Suspension provides the drive r with the opportu nity to
set the chassis characte ristics also to the ir individual preference.
W ith the dr iv in g m odes
standard, automatic and dynamic the d river
has three chassis sett ings available, ranging from comfort to sporty.
In add it io n,
lift prov ides a fourth mode whi ch can be sele cti ng fo r
dr iving over poor stretches of road =:>

T he modes a re set in MM I

On veh icles equipped w ith the sport su spen sion Adaptive A ir Suspen­
sion -Sport *, there is genera lly more emphasis on a sporty chassis
sett ing. Setti ngs ra nge from comfo rtable to fi rm=:>

Chassis Cont rols" .
0 Note
• Whenever you park you r vehicle, always ma ke su re there is
adeq uate clea rance above and below t he ve hicle. The heig ht of the
parked veh icle ca n change as the res ult of temperature fluctuat ions,
c hanges in loa d cond ition and changes in the dr iv ing mode (ground
cleara nce) .
• M ount t he tie-down ch ains/ cables over the r unning s urfa ce
(circumfere nce) of the tires . Never secu re the vehicle by the axle, the
suspension st ruts or the front o r re ar tow line eye . For technical
reaso ns, the pressure in t he suspension struts may change dur ing the
transport and this will adverse ly affect vehicle handling.
• To prevent damage to the vehicle u nderbody, remembe r th at your
veh icle is no t an off- road vehicle, even in the lift mode. The ground
cleara nce is insufficient for this type of operation .
• If yo u are go ing to tow a tra il e r, you mus t act iv a te the trai le r oper ­
ation mode =:>

[I] Tips
Before you ca n ra ise your vehicle using the vehicle jack (fo r examp le ,
w hen changing a flat tire) you must activate the jacking mode

Chassis Controls
Four different driving modes can be set by the driver .
The automatic control processes are speed- and time-dependent . For
example, it is not poss ible to raise the suspension to the lift mode
above certain speeds .
When a speed of about 75 mph (120 km/h) is exceeded for more than 30 seconds, the vehicle is automatically lowered approximately 1
inch (25 mm) to a level suitable for highway speeds, except in the
standard mode . Road ho ldi ng is opt imized as a result of the lowe r
center of gravity and fue l consumption is reduced as a result of
reduced wind resistance.

• Lowering : When a speed of about 75 mph (120 km/h) is exceeded
for more than 30 seconds, the vehicle is automatically lowered by about 1 inch (25 mm).
• Raising: The vehicle is automatically ra ised aga in if the speed falls
below about 44 mph (70 km/h) for a period of 120 seconds. The
vehicle is ra ised immediately when speed falls below about 22 mph
(35 km/h).

of the reduced ground clearance.
If you switch off the engine whi le the vehicle is in the dynamic mode
and then switch on the ignition once aga in, the
c.::> warning light will
also come on again for a few seconds.
• Lowering : When a speed of about 75 mph (120 km/h) is exceeded
for more than 30 seconds, the vehicle is automatically lowered by an
additional 0.2 in (5 mm) .
• Raising: The vehicle is automatically raised again if the speed falls
below about 44 mph (70 km/h) for a period of 120 seconds. The
vehicle is ra ised immediately when speed falls below about 22 mph
(35 km/h).
standard
Select the standard mode if you desire a suspension sett ing with a
special emphasis on comfort . In the standard mode there is
no
lower ing of the s uspens ion. Even at high speeds, the vehicle stays at
the same level. Damping characteristics with a decided emphasis on
comfort are selected in this mode.
lift
Select the lift mode when you have to travel over poor sections of
road (e .g . trails) . In the lift mode, the vehicle is raised by 1 inch (25
mm) compared to normal level while it is still stationary and damping
characterist ics are adjusted to emphasize comfort .
The lift mode can be activated only at speeds below 50 mph (80 km/h). When a speed of about 62 mph (100 km/h) is exceeded, the
system automatica lly leaves lift mode and the mode set previously
(standard, automatic, dynamic) is activated again .•

& WARNING (co ntinued )
• Always make sure that the side airbag can inflate without
interference:
-Never install se at covers or replacement upholstery over the
front seatbacks that have not been specifically 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 sy stem can be activated only once. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary.
• The airbag sy stem can be deployed only onc e. After an airbag
has been deployed, it must be replaced w ith new replacement
parts de signed and approved es pecially 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 pyrotechni c
circuit interrupter .
- Work on the pyrotechnic circu it interrupter must only be
performed by a qualified dealer -risk of an a ccident!
- If the vehicle or the circu it interrupter is scrapped, all appli­
cable safety precautions must be followed .

tire-r im combinations not approved by Aud i, lower ing t he veh icle,
c hang ing the st iffness o f the suspe nsio n, incl uding the s prings,
s u spension str uts, shoc k absorbe rs etc. can change the forces that
