A ppl ies to vehicles: with Ada ptive Ai r Susp en sio n
This II warning/indicator light has the fol­
l owing f unctions:
- It illuminates for a few seco nds after the ig­
nition is t urned on as f unct ion check and
then goes out . -
If the warning/indicator light illuminates or
blinks contin uously, there is a system fault
in the Adaptive Air Suspension. A system
fau lt can result in lim ited ride comfort and
lo w ground clea rance . Drive safely to the
nearest authorized Audi dealer or qualified
wo rkshop, and have the fault corrected.
- If the warning/indicator light flashes, you
should not dr ive the veh icle . The flashing
warning/indicator light points to an extreme H igh level. A very
pronounced lifting of the
veh icle (ext reme H igh leve l) can result, for
examp le, when a heavy load is removed
from the vehicle. As soon as the level has re ­
t u rned to norma l, the wa rning/indicator
light stops flashing, and you can drive away.
- If the warning/indicator lig ht flashes in con ­
junction with the. warning/indicator
light, you should not dr ive off immediately
in order to prevent damage to the under­
body. The two warn ing/ indicator lights
flashing together points to an extreme Low level. A ve ry
pronounced lowering of the ve­
hicle (extreme Low leve l) can result, for ex­
ample, from a heavy load. As soon as the
level has retu rned to normal, the warn ing/
ind icator lights stop flashing, and you can
drive away.
(D Note
If the w arning/ indic ator l igh t flas hes in

Adaptive Air Suspension
Air suspension and damping
Description
App lies to vehicles: with Adapt ive Air S uspe nsio n
Air suspension and damping con be adjusted
separately.
Adaptive A ir Suspension is an electronically
controlled springing and damping system.
This chassis system makes it easier on the
driver by adapt ing to the particular situation
through imperceptible control processes.
The
Adaptive Air Suspension component reg ­
ulates ground clearance depending on vehicle
speed and driver input. It functions independ­
ently from the load condition . Accelerating to
a speed above a predetermined limit will make the vehicle lower itself. On the other
hand, driving more slowly results in the vehi­
cle raising again at specific speeds.
The
damping component provides individual
control of the damping forces . For example,
w ith damping characterist ics set to provide
greater comfort, damping is set somewhat
harder for a br ief per iod only as required, for
example, when go ing aro und a curve or when
braking.
Settings
Adapt ive Air Suspension prov ides the driver
with the opportun ity to set the chassis charac­
ter istics also to their individual preference.
W ith the driving modes
Comfort, Automatic
and Dynamic the driver has three chassis set­
tings available, ranging from comfort to spor­
ty. The
Offrood mode can be selected for driv­
ing on poor quality stretches of road. In addi­
tion,
Lift provides a fifth mode, which can be
selected when exceptionally high ground
clearance is needed
c::;, page 157, Chassis con ­
trols .
The modes are set in MMI <::;,page 159.
Adaptive A ir Suspension 157
A WARNING
The height of the parked vehicle can
change due to temperature fluctuations or
changes in load .
@ Note
-Whenever you park your vehicle, a lways
make sure there is adequate clearance
above and below the vehicle. The he ight
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 be ing t ransported (e.g .
by tow truck, train, ship, etc.), mount the
tie-down chains/cables over the running
surface (circumference) o f the tires. Nev­
er secure the vehicle by the axle, the sus ­
pension struts or the front or rear tow­
line eye . For technica l reasons, the pres­
sure in the suspens ion struts may change
dur ing the transport, which could result
in the vehicle no longer being secured
properly.
- If you are going to tow a trailer with a
trailer hitch that was
not installed ac­
cording to factory specif ications, you
must activate the traile r operation mode
man ually
<::;,page 161.
(D Tips
-Before you can raise your vehicle using
the vehicle jack (for example, when
chang ing a flat tire) or a vehicle lift, yo u
must activate the jacking mode
c::;, page 161.
-On some models, the vehicle can reach
its maximum speed only in the
Automat ­
ic
and Dynamic modes.
Chassis controls
App lies to vehicles : wit h Adaptive A ir Suspensio n
Five different driving modes can be set by the
driver.
T he automatic control processes are speed­
and time-dependent. For example, it is not

158 Adapti ve Air Susp en sion
possible to raise the suspension to a h igh level
above certain speeds .
When a speed of about 75 mph (120 km/h) is
exceeded for more than 30 seconds, the vehi­
cle is automatically lowered to
low level when
in comfort and automatic mode. Ground
clearance is about 0.6 inch (15 mm) less,
compared to the
normal level.
When a speed of about 100 mph (160 km/h)
is exceeded for more than 20 seconds, the ve­
h icle is automat ica lly lowered to
highway lev­
el
when in automatic and dynamic mode.
Ground clearance is about 1.4 inches (35 mm)
less, compared to the
normal level. Road
hold ing is optimized as a result of the lower
center of gravity, and fuel consumption is re­
duced as a result of reduced wind resistance.
Level adjustment Ground clearance
high level 2 about 9.4 inches
(2 40 mm)
high level 1 about 8 inches
(205 mm)
normal leve l about 7 inches
(180 mm)
low level about 6.5 inches
(165 mm)
highway level about 5 .7 inches
(145 mm)
The segment disp lay @ in the MMI Display
c:::> page 159 or in the instr ument cluster dis­
p lay
c:::> page 160 shows the current veh icle
level.
Automatic
Select the automatic mode if you prefer a bal­
anced, comfortable suspension setting . The
damping characteristics are adjusted accord­ ingly.
- Autom atic lowe rin g: When a speed of
about 75 mph (120 km/h) is exceeded for
more than 30 seconds, the vehicle is auto­
matically lowered by about 0.6 inch (15
mm) to the
low level, wh ich is more suitable
for highway speeds. Road hold ing is opti­
mized as a result of the lower ce nter of grav- ity and fuel consumption is reduced as a re
­
sult of reduced wind resistance . When a
speed of about 100 mph (160 km/h) is ex ­
ceeded for more than 20 seconds, the veh i­
cle is automatically lowered by an addit ional
0.8 inch (20 mm) to
highway level .
-Automat ic raising: When the vehicle is at
highway level and the speed falls below
about 80 mph (130 km/h) for more than 20
seconds, the vehicle is automatically raised
to
low level. Th e vehicle is automatically
raised aga in to
normal level if the speed
fa lls below about 44 mph (70 km/h) for a
pe riod of 2 minutes . The vehicle is raised im ­
mediately when speed fa lls below about 22
mph (35 km/h).
Dynamic
Se lect the dynam ic mode if yo u pre fer a spor­
ty suspension se tti ng. In t his mode, the veh i­
cle is lowered to
low level while it is still sta­
t ionary and sporty damping characteristics
are selected . The warning light. in the in­
strument cluster will come on for a few sec­
onds just to rem ind you 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 . warn ing light will
also come on again for a few seconds as a re­ minder .
-Automat ic lowe ring: When a speed of
about 100 mph (160 km/h) is exceeded for
more than 20 seconds, the veh icle is auto­
mat ically lowered by 0.8 inch (20 mm) to
highway level .
-Automa tic raising: The vehicle is automati­
cally ra ised to
low level aga in, if the speed
fa lls below about 80 mph (130 km/h) for a
pe riod of 20 seconds. The ve hicle is raised
immed iate ly w hen speed falls be low about
22 mph (35 km/h).

mode.
- Automatic lowering: When a speed of
about 75 mph (120 km/h) is exceeded for
more than 30 seconds, the vehicle is auto­
matically lowered by 0.6 inch (15 mm) to
low level .
-Automatic raising: The vehicle is automati­
ca lly raised to
normal level again, if the
speed falls below about 44 mph (70 km/h)
for a period of 2 minutes . The vehicle is
raised immediately when speed falls below
about 22 mph (35 km/h) .
Offroad
Select the offroad mode when you have to
travel over poor quality sections of road (e .g.
trails). In th is mode, the vehicle is raised to
high level 1, and damp ing characteristics for
poor road stretches are selected . When
sw itch ing to offroad mode , the Adaptive Air
Suspension indicato r appears automat ically in
the instrument cluster display¢
page 160.
The offroad mode can only be activated at
speeds below 37 mph (60 km/h) . Offroad
mode ends automatically and the automatic
mode is activated when a speed of approxi­
mately 50 mph (80 km/h) is exceeded.
Lift
Select the lift mode when except ionally high
ground clearance is needed at a reduced
speed. In this mode, the vehicle is raised to
high level 2. When switching to lift mode , the
Adaptive A ir Suspension indicator appears au­
tomatically in the instrument cluster display
¢ page 160.
The lift mode can be activated only at speeds
below 12 mph (20 km/h). When a speed of
about 25 mph (40 km/h) is exceeded, the sys­
tem automatically leaves lift mode and the
offroad mode is activated. The instrument
cluster display automat ically switches the dis­
play to Adaptive Air Suspens ion to indicate re­
duced ground clearance .
