Roof rack
First things first
A roof rack can be fitted to carry additional luggage on
the roof.
- Always read and follow the i nstructions provided by the
roof rack manufacturer when t he roof rack system must
be installed.
If you are transporting luggage or other objects on the roof, please
note the following:
• Your vehicle has specially designed aerodynamic roof rails. On ly
install a roof rack specifically designed for your model. Contact the
nearest Audi dealer for information on approved modu lar roof racks
f or your vehicle.
• These approved roof racks are the basis for a complete roof rack
system. Addit ional attachments for the basic roo f rack are neces­
sary to safely transport luggage, bicycles, surf boards, skis or small
boats . All necessary hardware for these systems is availab le at your
authori zed Audi dealer.
• We recommend that you keep the installation instructions for
your roof rack system together with your Owner's literature in the
veh ic le.
Wh en should th e roof ra ck b e remo ved?
• Before going through an automatic car wash (it is best to ask the
car wash operator for advice).
• When not in use, to reduce fuel consumption, wind noise and to
guard against theft .

& WARNING
• Use of an unappr oved roof r ack or in corre ct mounting of an
a pp ro ved roof r ack can cau se the roof rack or the ite ms attached
t o it t o fa ll off th e ro of ont o th e road .
• Obj ec ts falling fr om the roof of a v ehic le can c au se a cr ash and
per son al inju ry.
• Onl y mo unt th e sys te m betwe en the marking s shown in

• The roo f rack sy stem mu st be in sta lled e xactly acc ording t o the
in stru ctio ns pr ov ided .
0 Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or moun ting structures not approved by
Audi for your vehicle. The same applies to damage resulting from
incorrect roof rack installation.
• Always check the roof rack mountings and hardware before each
trip and during a trip to make sure everything is securely tightened .
If necessary , retighten the mountings and check the entire system
from time to time.
• After mounting a roof rack system, or when you transport
objects on the roof of your vehicle, the height of the vehic le is natu­
ra lly increased . Be careful when driving under low bridges or in
parking garages for examp le . This could cause damage to the load
and even the vehicle itself. •

If the vehicle in front accelerates, Adaptive Cruise Control a lso accel­
erates up to the speed tha t you have set.
Si tu ation requiring d river interv ention
In some situa tions you will have to use the footbrake to s low the
vehic le down in order to keep a safe distance from vehicle in front
of you or to avoid a rear -end collision . In this situa tion, a symbol
appears and a warning tone sounds~
page 146.
P ass ing an ot her vehicle
If you move into the passing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set
and maintains it.
O ve rrid e
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you re lease the acce lerator pedal, the system
adjusts back down to the speed you previously set.
[ i ) Tips
Please note that the amount of acceleration the Adaptive Cruise
Control uses depends on the Distance se tt ing selected. DISTANCE 1
gives you acceleration that is dynamic and sporty . DISTANCE 4 , on
t he other hand, gives more moderate acce leration . For more infor ­
mation about the time intervals~
page 140, "H ow is the distance
(time interval) set?" .
• Please note that if the Adap tive Cruise Contro l has begun braking
t he vehicle and the driver chooses to brake the vehicle additiona lly,
the brakes may feel "hard". This is s imply due to the pressure build­
up of the initial braking.
• Adaptive Cruise Contro l is switched off after pressing the foot­
b rake . The speed saved up this point can be resumed . To resume the
saved speed, release the brake pedal and press the contro l lever
:;) page 139, "Turning Adaptive Cru ise Contro l off temporarily" .•

Adaptive Air Suspension
Adaptive Air Suspension and
Damping
A pplies to veh icles: with Adaptive 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 . Th is 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 183, "Chassis controls". The modes are set in
MMI:::::,
page 183.
& 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 184.
[ 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 184. •

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.

Select the dynamic mode if you prefer a sporty suspension setting .
In this mode, the vehicle is lowered whi le it is still stationary and
spo rty damping characteristics are selected . The warn ing light

in the instrument cluster will come on for a few seconds just to
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

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. •

(The term "ISOFIX" regarding lower anchorages had been used by
Audi and other manufacturers in the past, but LATCH is now the
standard name for the new child restraint anchorage system.)
Some child restraint system manufacturers have been providing
tether straps on certain models of their child restraint systems, either as standard equipment or as a retrofit, for several years .
Check with the manufacturer of the child restraint system for tether
strap availability .
To provide a simpler and more practicable way to attach the child restraint system on the vehicle seat, U .S . Federal regulations require
the phase -in of lower anchorages in vehicles and devices on new
child restraint systems to attach to the vehicle anchorages.
Child restraint system manufacturers will probably off er two kinds
of lower anchorages on their child safety seats
They could come with:
• hooks or other latches attached to adjustable straps or
• rigid latches on bars that extend out the back of the child
restraint and are released with release buttons at the bottom of the
child restraint.
In addition to the LATCH lower anchorages, bo th of these child
restraint systems use tether straps to help keep the child restraint
system firmly in place .•
Where can I get additional information about
child restraint application and usage?
There are a number of sources of additional information about child
restraint selection, installation and usage:
NHTSA advises that the bes t child safe ty seat is the one that fits
your child and fits in your vehicle, and that you will use correctly and
consistently.

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) * and fully loaded vehicles .

Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitations
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumption by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketbook.
[ i ] Tips
The consumption estimates as published by ENV IRONMENTAL
PRO TEC TION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
-Avoid unnecessary accelerat ing and braking.
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car 's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by

• The vehicle capacity weight figures apply when the load is
distributed evenly in the vehicle (passengers and luggage). When
transporting a heavy load in the luggage compartment, carry the
load as near to the rear axle as possible so that the vehicle's
handling is not impaired.
• Do not exceed the maximum permissible axle loads or the
maximum gross vehic le weight. Always remember that the vehic le's
handling will be affected by the extra load. Therefore, adjust your
speed accordingly .
• Always observe local regulations. •
Dimensions
The specifications refer to the basic model. Differences may occur
depending on the mode l type and options ordered, for example, tire
sizes.
0 Note
When driving up steep ramps, on rough roads, over curbs, etc. it is
important to remember that some parts of your vehicle, such as
spoilers or exhaust system components, may be close to the
ground. Be careful not to damage them. •
