Vehicle OP-eration
Some vehicles moving up ahead in your lane of travel are difficult to
detect, for example two-wheeled vehicles, vehicles with high ground
clearance, loads sticking out the back . Vehicles like this are often
detected late or in some situations not at all. •

Adaptive Air Suspension and
Damping
Ap plies to veh icles: w ith Ad aptive Ai r Suspens ion
Description
Adaptive Air Suspension and damping can be regula ted
and they adapt automatically to a request from the
driver and the driving situation at the time .
Adaptive Air Suspension is an e lectron ically controlled springing and
damping system . This chass is system makes it eas ie r on the driver by
adapting to the particular situation th rough impe rceptible contro l
processes .
The
Adaptive Air Suspension component regu lates ground clearance
depending on ve hicl e speed, load cond ition and driver input.
W hen the system is in a utomatic mode, accelerat ing to a speed above
a predete rm ined limit will make the vehicle lower itsel f. On t he othe r
hand, driv ing more slowly res ults in the vehicle ra is ing again at
specific speeds.
Th e
damping component provides individua l control of the damping
forces. For example, with damp ing characterist ics set to provide
greater com fort, damp ing is se t somewhat harder for a br ief period
only as required, for example, whe n going around a curve or over
rough road sur faces as we ll as when braking .
Settings
Adaptive Air Suspension prov ides the drive r wi th t he opportu nity to
set the chass is characterist ics also to their individual preference.
W ith the driving modes
Comfort, Automatic an d Dynamic the dr ive r
has three chassis sett ings available, ranging from comfort to sporty.
In addit ion,
Lift p rovides a fourth mode which can be selecting fo r
dr iving over poor stretches of road =>
page 169, "Chass is controls" . The modes are set
in MM I =>
page 169.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuation s or changes in load .
0 Note
• Whenever you park yo ur vehicle, always make sure there is
adeq uate clearance above and below the ve hicle . T he heig ht of the
parked vehicle can change as the res ult of temperature fluctuations,
chang es in load condition and changes in the dr iv ing mode (ground
clearance).
• If the veh icle is be ing transported (e .g. by tow truck, train, ship,
etc.) , mount the tie-down cha ins/cables over the r unning s urface
(c ircumfere nce) of the tir es. Never sec ure the ve hicle by the ax le, the
suspension struts or the front or rea r tow line eye. For technical
reaso ns, the p ressure in t he suspension st ru ts m ay change dur ing the
transport, w hic h could result in the vehicle no longer being secured
pro perly.
• To prevent damage to the vehicle underbody, remember that your
veh icle is no t an off-roa d veh icle, even in the "lift" mo de. Th e ground
clearance is insufficient for this type of operation.
• If you are go ing to tow a trai ler, you mus t activate the trai ler ope r
ation mode =>

[ i ] Tips
Before you raising your vehicle us ing the veh icle jack (for example,
w hen c hanging a flat tire) you must acti va te the j ack ing 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 possible to raise the suspension to the lift mode
above certain speeds.
Automatic
Select the automatic mode if yo u prefer suspens ion and damping
settings emphasizing comfort.
• 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 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 resistance.
• Raising: The vehicle is automatically raised aga in if the speed falls
below about 44 mph (70 km/h) for a period of 2 minutes. The veh icle
is raised immediately when speed falls be low about 22 mph (35
km/h).
Comfort
Select the comfort 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 suspens ion. Even at high speeds, the veh icle stays at
the same level. Damp ing characteristics with a decided emphasis on
comfort are selected in this mode.
Dynamic
Select the dynam ic mode if you prefer a sporty suspension sett ing. In
this mode, the vehicle is lowered while it is still stationary and sporty
damping characteristics are selected. The warning light
c.::> in the
instrument cluster will come on for a few seconds just to remind you
of the reduced ground clearance.
Controls and equip
ment Safety first
If you switch off the engine while the vehicle is in the dynamic mode
and then switch on the
ignition once again, the
c.::> warning light will
also come on again for a few seconds as a reminder.
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 0.6 inch (15
mm) compared to normal level while it is still stationary and damping
characteristics 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 .•

steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when turning the steering wheel at low
speeds (for example when parking), - more effort will be required
than usual.
• Be aware of the different than usual steering response and adjust
your steering force accordingly.
• Have the prob lem checked and set right by an Audi dealer as soon
as possible.
[ i ] Tips
• When the engine is running, never hold the steering wheel turned
all the way to the right or to the left for longer than 15 seconds . The
power steering pump will overheat the hydraul ic fluid if you keep
holding the steering wheel turned all the way . This is likely to damage
the power steering system.
• If the power steering system should fail entirely, or if the engine
is not running (for examp le, while be ing towed), you will still be able
to steer the vehicle. However,
considerably more effort will be
required to do so.
• If the power steering system should have a leak, or is not func
tioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydra ulic fluid. The power steering reservoir is the one located most
forward on the left side of the engine compartment=>
page 280. The
correct fluid level in the reservoir is important for proper functioning
of the power steering . •
A pp lies to veh icles: with All W heel Dr ive
Driving with your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels . This
happens automatically depending on your driving style and the road
conditions at the time . See also=:>
page 243, "Electronic different ial
lock ( EDL)".
Winter tires
When driving in the winter, your vehicle with A ll Wheel Drive has an
advantage , even w ith regular t ires . In winter road condit ions it may
be advisable to mount winter tires (or all-season tires) fo r improved
dr iveability and braking: these tires must be mounted on
all four
wheels.
See also =:> page 311, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally also
applies to vehicles with A ll Whee l Drive=:>
page 312, "Snow chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same size .
Also avoid tires with different tread depths . For details see page
=:>
page 307, "New tires and replacing tires and wheels ".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle . It is therefore best to avoid rough tracks and uneven
terrain as much as possible. Also refer to=>
page 252.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
