immediately at low speed to the nearest
authorized Audi dealer or qualified repair
facility and have the brake system i n­
spected .
- Always keep in m ind that after several
brake applicat ions, you will need greater
pressure on the brake peda l to stop your
vehicle . Do not re ly on stra ined brakes to
re spond w ith maxim um stopp ing power
in cri tic al situa tions. You mus t all ow for
increased bra king distances. The extra
distance used up by fading brakes could
lead to an accident.

Instruments and warning/indicator lights 21
@ Tips
Have the bulb replaced or the connection
repaired by your authorized Audi Service
department.
~()) Headlight range control
II Headlight range control: defective!
If
the symbol illuminates, the headlight range
contro l is no longer working properly . Have
the system checked and repa ired at your Aud i
dealer .
l§O Adaptive Light
Applies to vehicles: with Adapt ive Light
rlJ Audi adaptive light: system fault
If the indicator light turns on and this mes­
sage appears, there is a malfunction in the
adapt ive light system. The headlights still
function .
Go to an authori zed dea lership to have the
headlights or the control unit for the Adapt ive
Light repaired .
~D Light/rain sensor
f'al Automatic headlights/automatic wipers:
system fault
If
the indicator light turns on and th is mes­
sage appears, the light/ra in sensor is not
functioning correctly .
For safety reasons the low beams are turned
on permanent ly w ith the switch in
AUTO.
However, you can continue to turn the lights
on and off using the light switch. You can still
control all funct ions that are independent of
the rain sensor through the windshield wiper
l eve r.
Contact your author ized Audi dealer as soon
as possible to have the prob lem cor rected.
¢ Q Turn signals
The indicator light blinks when you use either
turn signal .
Whenever you use the left II or the right rl
turn signal, the indicator light blinks. When
you use the emergency flashers, both indica­
tor lights flash .
If one of the turn signa l light bulbs burn out,
the turn signal will blink twice as fast as nor­
mal. Carefully dr ive to your authorized Audi
dealer immed iately to have the malfunction
corrected. The ind icator light does not indi­
cate a malfunction if a turn signal on the tra il­
er or on the vehicle fails in trailer towing
mode.
(D Tips

Parking
Various rules apply to prevent the parked ve­
hicle from rolling away accidentally .
Pa rkin g
.. Stop the vehicle with the foot brake .
.. Pu ll the switch(®) to apply the park ing
brake.
.. Select the
P selector lever position
~page 102 .
.. Turn the eng ine off ~,&. .
In addition on inclines and grade s
.. Turn the steering wheel so that your vehicle
will roll against the curb in case it should
start to move .
A WARNING
-When you leave your veh icle - even if on­
ly b riefly - always take the ignition key
with you. This applies particu la rly when
children remain in the veh icle . Otherw ise
the chi ldren could start the engine, re ­
lease the parking brake or operate elec­
trical equipment (e.g. power windows) .
There is the risk of an accident .
- When the vehicle is locked, no one - par­
ticularly not children sho uld remain in
the vehicle. Locked doors make it more
difficult for emergency workers to get in­
to the vehicle - putting lives at risk.
Starting from rest
The star ting assis t func tion ensures tha t the
parking brake is released automatically upon
starting .
Stopp ing and appl ying park ing b rake
.. Pull the switch<®) to apply the park ing
brake.
Startin g and automatically relea sing the
pa rking br ake
.. When you start to drive as usua l, the park ­
ing brake is automatically re leased and your
vehicle begins to move.
On th e ro ad 75
When stopping at a traffic signal or s topping
in city traffic, the parking brake can be ap­
plied. The vehicle does not have to be he ld
with the footbrake . The parking brake elimi­
nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usual,
the parking brake is released automatically
and the veh icle starts to move .
Starting on slope s
When starting on inclines, the starting assist
prevents the vehicle from un intent ionally roll­
i ng back. The braki ng force of the parking
brake is not released unti l suff ic ient driving
fo rce has been built up at the wheels .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the d riv­
er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch<®> pulled and depress the
accelerato r. The parking brake stays applied
and prevents the vehicle from roll ing back­
ward .
.. You can release the switch<®) once you are
sure that you are developing enough for­
wa rd momentum at the whee ls as you de­
press the acce lerator .
Depend ing on the weight of the rig (veh icle
and t ra iler) and the severity of the incline, yo u
may ro ll backwards as yo u start . You can pre ­
vent rolling backwards by holding the parking
brake switch (®) pulled out and accelerating -
just as you would when starting on a hill with
a conventiona l hand brake.

94 Audi side assist
right of your travel lane, depending on wheth­
er you drive in the center of your lane or closer
to the edge.
If you drive in narrow lanes, s ide ass ist's de­
tection area may a lso include other lanes -es­
pecia lly if you tend to drive on the edge of
your lane¢
fig. 99. Under these condit ions,
vehicles can also be detected that are two lanes away, and side assist then could switch
between the informat ional and warning stage
signals .
When driving in very w ide lanes, vehicles in
the adjacent lane may not be detected be­
cause they are not inside the detection area .
Notes
Messages in instrument cluster display
Applies to vehicles: with side assis t
If side assist turns off automatically, the indi­
cator light on the button wi ll go out and you
will see a message in the instrument cluster
d isplay:
Audi side assist: not available. sensors
blocked
The side assist sensors are built into the rear
bumper on the left and right (not visible on
the outside)
¢ page 88, fig. 91 . To ensure that
you do not adversely affect the way side assist
functions, foreign objects (such as stickers or
b icycle racks) should not be attached to the
a rea on the rear bumper where the sensors
are located. If side assist functions are ad­
versely affected, you will see this message in
the instrument cluster display. Remove any ­
thing that may be blocking the sensors .
If no vehicle is detected for a longer period of
time while driving, side assist will also switc h
off a utomatica lly.
Audi side assist currently not available
If there is a temporary problem (such as the
ve hicle's battery charge being low), s ide ass ist
cannot be activated tempo rari ly.
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Audi side assist: not available when
towing
T he radar senso r's view is limited when tow­
ing a trai le r. For vehicles with a fa ctory instal ­
led towing hitch or a trailer hitch that was in­
stalled later according to factory specifica­
tions, side assist is automatically deactivated
as soon as the electrical connection to the
trailer's electrical socket is made, and this sta­
tus message appears in the instrument clus ­
ter display . Deactivation cannot be guaran­
teed when using a retrofitted towing hitch
that was
not installed according to factory
specifications.
Safety tips
Appl ies to vehicles : wi th side assist
The side assist detection may be limited when
driving aro und narrow street corners, on hilly
streets, and under poor weather cond itions.
It is possible that the radar sensors may also
detect other objects, such as high or stag­
gered guardrails .
Side assist does not measure actual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
o n this ass umed lane width . When driving on
narrow roads or when driving to the left or
right of the center of a trave l lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using.
A WARNING
- Improper reliance on the side assist sys­
tem can cause collis ion s and serious per­
sonal injury:
- Never rely only on side assist when
changing lanes .
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un-
der all conditions- danger of accident! ..,.

segments move closer to the vehicle. The col­
lision area has been reached when the next to
last segment is displayed. Do not continue
driving farther
c:> ,& !
A WARNING
- Sensors have blind spots in which objects
cannot be detected . Pay special attention
to small children and animals because
the sensors cannot always detect them .
- The parking system cannot replace the
driver's attention. The driver alone is re­
sponsible for parking and similar driving
maneuvers.
-Always keep your eyes on the veh icle's
surround ings, using the rear
view mirror
as well.
(D Note
Low obstacles already signaled by a warn­
ing can disappear from the system 's detec­
tion range as they are approached and will
not continue to be signaled. Objects such
as barrier chains, trailer draw bars, thin
pa inted vertical poles or fences may not be
detected by the system, posing risk of
damage.
(D Tips
- The sensors must be kept clean and free
of snow and ice for the park assist to op­
erate.
- You can change the volume and pitch of
the signals as well as the display
<=> page 113.
-What appears in the display is time-de­
l ayed.

We recommend that you practice park ing with
the rear v iew camera in a traffic-free locat ion
or parking lot to become familiar w ith the sys­
tem, the orientation l ines, and their funct ion .
When doing th is, there shou ld be good light
and weather conditions.
In the MMI display, objects or vehicles appear
closer or further away if:
- you are driving in reverse gear from a level surface onto an incline or a downward slope,
- you are driving in reverse gear toward pro­
truding objects,
- the vehicle is carrying too much load in the
rear.
The accuracy of the orientat ion lines and blue
surfaces diminishes if: -
the rear view camera does not provide a reli­
ab le image, for example, in poor visibility
conditions or if the lens is dirty,
- the image on the screen is not visib le due to
sun glare and reflection.
Caring for the rear view camera lens
T he rea r view camera is located above the rear
lic ense plate bracket. For the parking system
to operate, the lens
r:!> fig. 121 m ust be kept
clean:
- Dampen the lens w ith a household alcohol­
based g lass cleaner, and then wipe the lens
clean with a dry cloth
c::> (D .
-Remove snow with a hand br ush and ice
preferably with a de-ic ing spray
c::> (j) .
_& WARNING ,= --Sensors have blind spots in which objects
cannot be detected . Pay specia l attention
to small children and an imals because
the sensors cannot always detect them.
- The parking system cannot replace the
driver's attention. The driver alone is re­
sponsible for parking and similar driving
maneuvers.
- Always keep your eyes on the vehicle's
surroundings, using the rear view mirror
as well.
- Do not allow yourself to be distracted
from traffic by the rea r view camera pic­
tures.
- If the position and the installation angle
of the camera has changed, for example,
after a rear end coll ision, do not continue
to use the system for safety reasons .
Hav e it checked by a qualified dealership.
(D Note
-Low obstacles a lready s ignaled by a
warning can disappear from the system's detection range as they are approached
and will not continue to be signaled. Ob­
jects such as barrier chains, trailer draw
bars, thin painted vertical poles or fen­
ces may not be detected by the system,
posing risk of damage.

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), ins talled by some manu­
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine f unction, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op­
erat ion for diagnostic and repa ir purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded w ith special equip­
ment.
Electronic stabilization
program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESP detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw) o ut of control and helps you to get the veh icle
back under contro l by se lectively braking the
whee ls, and/or reducing engine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr ive r's intended cou rse. The in­
dicato r light
G] in the instrument cluste r
blinks when ESP is taking action to help you
control the veh icle.
ESP has l imitations.
It is importa nt to remem­
ber that ESP cannot overcome the laws of
physics. It will not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESP may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of dry road that is sudden ly covered w ith water,
s lush or snow, ESP cannot perform the same
way it wou ld on the dry surface . If the ve hicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle be cause con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESP cannot a lways deal as effectively
with difficult driv ing situations than at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESP can­
not override the vehicle's physical limits, in­
crease the availab le tract ion, or keep a ve hicle
on the road if road departu re is a result of
drive r inattent io n. Instead, ESP improves the
poss ibil ity of keeping the vehi cle under con ­
trol and on the road during extreme maneu­
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
ca uses you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
