Adaptive Air Suspension
Air suspension and damping
Applies to vehicles: with Adaptive A ir Suspens ion
Description
Air suspension and damping can be regulated as desired
by driver, and they adapt automatically to the driving situ­
ation at the time.
Adaptive Air Suspension is an electronica lly contro lled 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 vehic le speed and driver inpu t. It functions inde­
pendently from the load condition. Accelerating to a speed above a
predetermined limit will make the vehic le 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
when braking.
Settings
Adaptive Air Suspension prov ides the driver with the opportunity to
set the chassis characteristics a lso to their individual preference.
With the driving modes
comfort, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty.
The
offroad mode can be selected for driving on poor qua lity
stretches of road. In addition, lift provides a fifth mode, which can
be selected when exceptionally high ground clearance is needed
=> page 207, "Chassis controls". The modes are set in
MMI:::::,
page 208.
& 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 vehic le. 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 veh icle 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 vehic le no longer being
secured properly.
• If you are going to tow a trailer with a trailer hitch that was
not
installed according to factory specifications, you must activate the
trailer operation mode manually:::::,
page 211.
[ i ] Tips
• Before you can raise your vehic le using the vehicle jack (for
example, when changing a flat tire) or a vehicle lift, you must acti­
vate the jacking mode:::::,
page 210.
• On some models, the vehicle can reach its maximum speed only
in the
automatic and dynamic modes. •

pillar. On Canada vehicles, the tire pressure label is located either on
t he driver's side 8 -pillar or inside the fuel fil ler flap. Inflate trailer
tires to trailer and tire manufacturers' specifications.
L ight s
The head light settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trai ler lights
are working properly.
Sa fety c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle . Leave enough slack in the chains to
permit turning corners. When you insta ll safety chains, make sure
they will not drag on the road when you are driving .
The chains should cross under the tra iler tongue to prevent it from
dropping in case of separation from the hitch.
0 Note
If you are going to tow a traile r, you must activate the trailer opera ­
tion mode =>
page 211, "Towing a trailer" .
Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the fo llow ing:
- Do not tow a loaded trailer when your car i tse lf is not
loaded .
- Be especia lly careful when passing other vehicles .
- Observe speed l imits.
- Do not drive at the maximum permiss ible speed .
Controls and equip­
ment Safety first Vehicle operation
Tr
aile r t owing
Always apply brakes early .
- Monitor the temperature gauge .
Weigh t dis tr ibution
Towing a loaded trailer wi th an empty car results in a highly
unstable dis tribution of weight . If this cannot be avoided , drive at
very low speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations .
Speed
The higher th e speed, the more difficu lt it becomes for the driver to
control the rig . Do not drive at t he maximum pe rmissible speed.
Reduce your speed even more
if load, weather or wind conditions
a re unfavorable -particularly when going downhil l.
Reduce vehicle speed
i mmedi ate ly if the trailer shows the slightest
sign of swaying.
Do not tr y to s top the swaying by accelerating .
Observe speed limits . In some areas, speeds for vehicles towing
trailers are lower than for regular vehicles .
Always apply brakes early. When driving downhill, shift into a lower gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coo lant t emperatu re
The coolant temperature gauge=> page 13 must be obse rved care ­
ful ly. If the need le moves close to the upper end of the sca le , reduce
speed immediately and/or turn off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts f lashing
- f- , pul l off the road, stop and let the engine idle for
about two minutes t o prevent heat build -up.
Vehicle care Do-it-yourself service Technical data

Fuel supply and filling your fuel tank
Blend of gasoline and ethanol (grain alcohol or ethyl alcohol}
• Anti-knock index must be 87 AKI or higher.
• Blend must not contain more than 10% ethanol.
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well for
winter or summer driving. During seasonal change -over, we suggest
that you fill up at busy gas stations where the seasonal adjustment
is more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to plastic and rubber components in
the fuel system.
• Do not use fuels that fail to meet the specified criteria in this
chapter.
• If you are unable to determine whether or not a particular fuel
blend meets the specifications, ask your service station or its fuel
supplier.
• Do not use fuel for which the contents cannot be identified.
• Fuel system damage and performance problems resulting from
the use of fuels different from those specified are not the responsi ­
bility of Audi and are not covered under the New Vehicle or the
Emission Control System Warranties.
• If you experience a loss of fuel economy or driveability and
performance problems due to the use of one of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
deposit build-up caused by the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another,
they have certain things in common. All gasoline grades contain
substances that can cause deposits to collect on vital engine parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine and fuel systems clean,
they are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the offi­
cial website (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.
(D Note
Damage or malfunction due to poor fuel quality is not covered by
the Audi New Vehicle Limited Warranty. •
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fuel filler flap.
If the power locking system should fail, you can still open the flap
manually - for detailed instructions see=>
page 329.
You can find the fuel tank capacity of your vehicle in Technical Data
=> page 399. .,_
