1,1 /. Rear spoiler: system malfunction!
The rear spoiler may not have extended due to
a malfunction. This could change the vehicle's
driving characteristics at high speeds. Do not
exceed 85 mph (140 km/h). Drive to your au­
thorized Audi dealer immediate ly to have the
malfunction corrected . The co lor of the indica­
tor light depend s on the veh icle speed.
A WARNING
Dr iv ing at higher speeds w ithout the rear
spoiler deployed can impair handling char­
acteristics, making the veh icle harder to
control.
-Always make sure that the spoiler is de­
ployed when driving at speeds over
85 mph (140 km/h). If th e rear spoiler
wa rning/ind icator light in the instru­
ment cluster comes on, the rear spoiler
may not have deployed.
- Never drive at speeds higher than
85 mph (140 km/h) if the spoiler is not
dep loyed. Have the spoiler inspected as
soon as possible by an authorized A udi
dealer or qualified workshop.
- Always obey speed limits and other traf­
fic laws.
A WARNING
Improper operation of the rear spoiler can
cause crushing injuries. -
Always make sure that nobody, especially
children, is in the way when the rear
spoiler is deployed or retracted.
(D Note
- Never push the vehicle or apply force to
the rear spoiler -it could be damaged.
- To prevent damage to the rear spoiler do
not lean or place anything on it .
- Only operate the rear spoiler man ually
when the rear lid is closed and the rear
spoiler moving parts are not blocked.
Otherw ise, damage co uld occur.
(D Tips
Clean the spoiler compartment every 2 to
3 months. The spoiler compartment must
always be free of ice, snow, leaves or other
debris.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving hab its
r:::;, ,& . On
vehicles that are either dr iven mostly in stop­
and-go city traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes , you sho uld use the braking
effect o f the engine . This way, you prevent un­
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter­
vals.
Moisture or road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking .,..

nearest Audi dealer or qualified work­
shop.
- Never let the vehicle ro ll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electromechanical
power assist, dynamic
steering
The electromechanical power assist helps the
driver when steering.
Power steering adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defective! Stop the vehicle
If this indicator light turns on and stays on
and this message appears, the power steering
may have failed.
Do
not continue driving. See your authorized
Audi dealer or other qualified repair facility
for assistance.
l>:r-ij Steering: System fault You can continue
driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cult to move or more sensitive than usual. The
steering wheel may also be at an angle when
driving straight.
Drive slow ly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected.
'Tl Dynamic steering: Initializing
If th is driver message appears and the ind ica­
tor light is flashing on the inst rument panel,
dynamic steering* is be ing reinitialized. After
starting the engine, the steering whee l wi ll
move slightly. Re-initialization might be nec­
essary if the steering wheel was moved hard
to the left and right while the vehicle was not moving. The display
goes out as soon as initi­
alization is complete.
Drive slowly to your authorized Audi dealer or
qualified wo rkshop to have the malfunct ion
corrected.
A WARNING
Have the dynamic steering * system mal ­
function repaired as soon as possible by an
authorized Audi dealer or qualified work­
shop -risk of accident!
(D Tips
If the . or '1:I indicator light only stays
on for a short time, you may continue driv­
ing.
- The dynamic steering* stability systems
are not availab le in the event of a system
malfunction .
- For additional information on dynamic
steering*, refer to¢
page 102.
Driving with your
quattro
-
With all-wheel drive, all four wheels ore driv­
en .
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 195.
A center differential distributes the driving
power variably to the front and rear axle.
It
works together with selective wheel torque
control, which activates when driving through
curves¢
page 196. With the sport differen­
tial*, power distribution to the rear wheels is
variable and can be adjusted with drive se lect
¢ page 102.
The all-wheel drive concept is des igned for
high eng ine power. Your veh icle is except ion­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions ¢,&. . .,.

than is being generated and ensures an opti­
mal state of charge for the battery.
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
li mited.
- If starting ability is threatened, the indi­
cator light (•) appears¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant e lectrica l energy is re­
quired, but only a little is generated.
It is also
crit ical if the engine is not running and electri­
cal components are turned on. In this in­
stance energy is being consumed but none is be ing generated .
It is in precisely these situations that you wi ll
notice energy management actively regulat­
ing the distribution of energy.
Vehicle stands for an e xtended period
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched
off.
This reduces energy consumption and main­
tains starting capab ility over a longer period.
Some of the conven ience functions may not
ope rate, such as the inter ior lights or the
power seat adjustment. The conven ience
f u nctions w ill be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned
off or use other MMI func­
tions, the battery is being discha rged .
If starting capability is jeopardized due to en­
ergy consumpt ion, the following warning ap­
pears in t he MMI display:
Please start the engine soon or the system
will be turned off.
The wa rn ing ind icates that the system will be
turned
off automatically after 3 minutes. If
you wish to continue using the functions, yo u
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicl e is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and t he battery's state of
charge is not opt imal.
To bring the energy ba lance back into equili­
brium , consumers which require especially
large amounts of energy are temporari ly cut
back or switched
off. Heating systems in par­
t icular require a great deal of energy. If you
notice, for example, that the heated seats" or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
off. These systems w ill be available again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slightly . This is normal and not
a cause for concern. By increasing engine idle
speed the addi tional energy requi red is gener­
ated and the batt ery is charged.

208 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always follow the operating
and driving instructions provided and use
common sense.
@ Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
c:::> page 208, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­ ble for your vehicle and trailer and must be
mounted securely on the vehicle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trai ler hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
c:::> A.
Trailer brakes
If your trailer is equipped with a brakin g sys­
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your Audi dealer for correct
wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is ion to the rear .
A WARNING
--
After removing the trailer hitch, do not
store it in your vehicle . In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shift ing forward,
backward or sideways.
Never allow a passenger to ride in a trailer
c:::> A in Driving instructions on page 210.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is important that the cooling system 's
performance is up to the additional load.

210 Trailer towing
A lways apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Air su spen sion *
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow­
ing a trailer. This will limit the regulation by
the air suspens ion while driving. Select in the
MMI:
! CARI function button> (C ar)* sys te m s
control button > Vehicl e se tting s> Air s usp .:
t o wing > On .
Coolant t emperatur e
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immed iate ly if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,
refer to. ¢ page 16 .
A WARNING
Anyone not properly restrained in a mov­
ing veh icle is at a much greater risk in an
accident. Never let anyone r ide in your car
who is not prope rly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight dist ribution. Safety, perform­
ance and economy w ill greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
have become comp letely familiar with the way your vehicle
-trailer combination behaves and
responds .
Backi ng up is diffic ult and requi res p ractice.
Backing up w ith a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trailer.
Maintai n a greater d ista nce between yo ur ve­
hicle and the one in fron t of yo u. You w ill need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that you cannot ac­ ce le rate as fast as you norma lly would be­
ca use of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang­
ing lanes again.
Avoid jerky starts, sharp tu rns o r rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 294.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
.,. App ly the foot brake .
.,. Have someone place choc ks unde r both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes unt il the whee l chocks absorb the
load .
.,. Turn the whee ls towards the curb.
.,. Apply the parking brake.
.,. Select the P selector lever posit ion.
When re sta rting after p ark in g :
.,. App ly the foot brake .
.,. Start the engine.

- To reduce the r isk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
t he wheel housings.
- After washing the vehicle, the braking ef­
fec t may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
Q) Note
- If you wash t he vehicle in an automatic
car wash, yo u must retrac t the rear spoil­
er if necessary, and fo ld the exter ior mir­
rors in to reduce the risk of damage.
Power folding exterior mirrors* must on­
l y be folded in and out using the power
fo ld ing funct ion.
- To prevent paint damage, do not wash
the veh icle in direct sunlight. -
To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fi nish paint. The paint cou ld be
damaged when the stickers o r magnets
are removed.
@ For the sake of the environment
Only wash the vehi cle in facilities spec ial ly
designed for that purpose . This will red uce
the risk of dirty water contam inated with
oil from entering the sewer system.
