matically =>& .
In the
AUTO position the low beams are switched off automatically
when the ignition is turned off.
Light Sensor Malfunction*
In the event of a light sensor ma lfunct ion, the driver is notified in the
instrument cluster display:
Automatic headlights/automatic wipers defective
For safety reasons the low beams are turned on permanently with t he
switch in
AUTO*. H owever, you can continue to turn the lights on and
off using the light switch. Have the light sensor checked as soon as
possible at a dealership.
Coming home/leaving home function*
The function is sw itched on when the sw itch is in the AUTO* position
and the function is shown as active in the driver information system.
The
coming home funct ion illuminates the area around the vehicle
when the ign it ion is switched
off and the driver's door is opened. The
length of time the lights rema in on can be set in the menu display
( Illumination > Exterior lights > coming home ).
The leaving home function illuminates the area around the vehicl e
when u nlocking it .
& WARNING
• Never use daytime running lights to see where you are going.
They are not bright enough and will not let you see far enough
ahead for safety, especially at dusk or when it is dark. Always
switch on the low beams at dusk or when it is dark.
• Automatic headlights are only intended to assist the driver .
They do not relieve the driver of his respon sibility to check the
headlights and to turn them on manually according to the current
light and visibility conditions. For example, fog and rain cannot be

detected by the light sensors. So always switch on the headlights
under these weather conditions and when driving
in the dark io.
• Crashes can happen when you cannot see the road ahead and
when you cannot be seen by other motorists.
- Always turn on the headlights so that you can see ahead and
so that others can see your car from the back.
(I) Tips
• With the switch in AUTO front fog lights cannot be turned on in
addition.
• Th e light senso r for headlight control is located in the rear view
mirror mount . Do not apply any stickers to the windshield in this area
to prevent malfunctions or fail ures .
• Some exterior lighting functions can be adjusted in the driver
information system => page 22 ,
• If you remove the ignition from t he ignition lock whi le the head­
lights are still on, a buzzer will sound as long as the driver's door is
open to remind you to turn off the lights .
• Always observe the specific local regulat ions for your area as to
when to use your lights.
• With automatic headlights, the high-beam funct ion is also avail­
able, but with one restr iction:
If you have not switched the high
beams back to low beams during automatic headlig ht operation (for
example, after driving through a tunnel), only the low beams come
on the next time automatic headlights are switched on . To use the
high beams, you first have to pull the high beam lever back and then
push the lever forwa rd again .
• In cool or damp weather, the inside of the headlights, turn signa ls
and ta il lights can fog over due to the temperature difference
between the inside and outside. They will clear shortly after switching
them on. This does not affect the serv ice life of the light ing . _,,

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieva l after an accident or crash event. ED R's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic contro l modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally recorded over a very limited period of time and stored when a
system fault or other condition is sensed by a control unit. Some of
the data then stored may relate to vehicle speed, direction, braking
as well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment.
Electronic Stabilization Program
(ESP)
General
The Electronic Stability Program increases driving
stability .
With ESP, contro l over the vehicle is increased in situations when the
vehicle is close to the limits of grip, such as dur ing accelerat ion and in
curves. ESP reduces the risk of sk idding and improves vehicle stability
unde r all road conditions.
It operates at all speeds.
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDS) and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
How ESP works
The ESP control unit processes the following data from high-sensitive
sensors: the rotationa l speed of the vehicle about its vertical axis,
fore-and -aft and lateral acceleration forces, brake pressure and
steering angle .
Us ing stee ring ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
actual vehicle behavior. If the two do not match, for example when
the vehicle beg ins to skid, ESP brakes the appropriate whee l auto­
matically.
The vehicle is stabilized aga in by the forces act ing on the whee l
during braking. With an oversteering veh icle (tendency for the rear
end to skid out of the curve), the brake app lication is mainly at the
front wheel on the outside of the curve, with an understeering vehicle
(tendency to run wide in the curve) at the rear wheel on the insid e of
the curve or additionally at the other wheels as needed. This brake
application is accompanied by noises. _,

Trailer towing

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation .
If you p lan to tow a t railer, p lease remember that the additional load
w ill affect durability, economy and performance.
Tr ailer towing not on ly p laces mo re s tress on the vehicle, it also calls
for more concentration from the driver.
For this reasons, a lways fo llow the operating and driv ing instr uctions
prov ided and use common sense .•
Technical requirements
Trailer hitch
Use a we ight-carrying hitch conforming to the gross trai ler weight .
Th e h itch mus t be suit able for your veh icle and t railer and mus t be
mounted securely on the vehicle's chassis at a
technically sound l oca­
t ion. Use on ly a tra ile r hi tch w ith removable b all moun t. Alw ays check
w ith the trailer hitch manufacturer to make sure that you are using
t he correc t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way t hat it does not interfere
w ith the impact -ab sorb ing bumper system. No mod ifi cations s houl d
be made to the vehicle exhaust and brake systems . From t ime to
t ime, che ck t hat all hitch mou nting bolts rema in securely faste ned.
W hen you are no t tow ing a trai ler, remove the trailer hitch ball
mount. This prevents the hitch from ca using damage should your
veh icle be s truck from behind=>&.
Tire pressure
When towing a tra iler, inflate the tires of you r vehicle to the cold tire
pressu re listed under "Full lo ad"on t he st ick er o n the r ight doo rjamb.
I n flate trailer t ires to trai ler and tire manufacturers' specifications .
Lights
The headlight settings should be checked with the tra iler attached
befo re d riving o ff. Have the headlights adjusted as necess ary s o that
you can see the road ahead but not b lind oncoming t raffic.
Check to make s ure bo th vehicle and t railer lights a re wor king prop­
er ly.
Engine cooling system
Towing a trailer ma kes t he engin e work harder. It is important t hat
t he cooling sys tem' s per formance stands up to the add ition al stra in.
M ake sure that the coo ling sys tem has eno ugh fluid .
Trailer brakes
If your trai ler is equipped with a braking system, check to be su re that
it confo rms to all regula tions .
Th e tra ile r hydrau lic brake system must not be directly con nected to
the vehicle's hydraulic b rake system.
Safety chains
Be sure trailer safety cha ins are p roper ly connected from the t rai ler
to the hitch on the vehicle. Leave enough s lac k in t he chai ns to permit
t u rni ng corners. When you insta ll safety chains, ma ke s ure t hey will
not d rag on t he road when yo u are d riving .
The chai ns should cross under the trailer tongue to prevent it from
drop ping in ca se of separat io n from t he hitch.
Trailer lights
Trailer lights must meet all regulat ions. Be su re to chec k w ith your
author ized A udi dealer for correct wiring, switches and relays. _.
