-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
ch anging lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side ass ist cannot detect a ll vehicles un­
der all cond itions- dange r of accident!
- Please note that side assist indicates
ther e ar e approaching vehicles, o r
vehicles in your bli nd spot, o nly afte r
yo ur vehicle has r eached a driving speed
o f at least 19 mph (30 km/h).
- In certain s ituati ons, the system may not
f unc tion or its funct io n may be lim ited.
For example:
- if veh icles are approaching or be ing left
behind very quick ly. The display may
not turn on in time.
- in poor weather condit ions such as
heavy ra in, snow or heavy m ist .
- on very wide lanes, i n tight curves or if
there is a rise in the road surface .
Vehicles in the adjacent lane may not
be detec ted becaus e they are outside
of t he senso r range.
(D Note
The sensors can be displaced by impacts o r
damage to the bumper, whee l housing and
unde rbody. This can affect the system .
Have your author ized Audi dealer or au­
t hori zed A udi Service Fa cility check the ir
function.

Park assist
Parking system
Applies to vehicles: with pa rking system
Different park assist systems may be used for
parking or maneuvering, depending on the
vehicle's features.
Parking system (rear)*:
For the parking system (rear), the acoustic
park assist system is installed in the rear of
the vehicle
¢ page 118.
The rear parking assist system uses ultrason ic
sensors to determine the distance of the vehi­
cle from a detected obstacle. There are a tota l
of four sensors located on the rear bumper
(two in the m iddle and two on the sides).
Parking system (rear, with rear view
camera)*:
For the parking system (rear, with rear view
camera),
the rear acoust ic park assist system
is integrated in the rear of the vehicle and the
rear view camera is integrated in the rear lid
¢page 121.
The parking system (rear, with rear view cam­
era)
uses ultrasonic sensors to determine the
distance of the vehicle from a detected obsta­
cle . There are a total of four sensors located
on the rear bumper (two in the middle and
two on the sides).
_& WARNING
Make sure the sensors are not covered by
stickers, deposits or any other obstruc­
tions as it may impair the sensor function.
For information on cleaning, refer to
qpage 202.
Parking system (rear)
Rear acoustic park assist
Applies to vehicles: with parking system (rear)
The rear acoustic park assist warns you of ob­
stacles or objects behind your car .
Description
The rear acoustic parking assist system deter­
mines the distance of the vehicle from an ob­
stacle using ultrasonic sensors. There are 4
sensors in the rear bumper.
The range at which the sensors start to meas­
ure is
about:
To the sid e 2 ft (0 .60 m)
Center rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is activated automati­
ca lly when
reverse gear is engaged. A brief
tone confirms that the system is activated.
Warning tones
Distance warning is given by warn ing tones
wh ich are generated by the rear signa l genera­
tor. The volume and the pitch of th e warning
tones can be adjusted in the MMI*
¢page 119.
Reversing
Distance warning when reversing starts when
an obstacle is detected in the range of the
parking assist system . As the distance de­
creases, the time interval between the a udible
tones becomes shorter.
When the distance is less than 1ft (0.30 m),
the tone becomes continuous. At this point
you should stop backing up .
Please note that low objects already signalled
by a war ning can disappear from the system's
detection range and will not continue to be
signalled .
If the distance to an obstacle remains the
same, the vo lume of the distance warning is
gradually reduced after about 4 seconds (this
does not apply in the continous tone range).
ll-

"" N
0 ::.,: co ,...., \!) 1.1'1 ,...., 1.1'1 ,....,
Approaching another obstacle will result in
the distance warning sounding at the normal
volume aga in.
Malfunction s in the s ystem
If a war ning tone is audible for about five sec­
onds when you turn on the ignit ion, there is a
mal function in the system. Have the problem
corrected by your authorized Audi dealer.
Keep t he sensors in the rear bumper clean and
free from ice so t hat the acoustic park assist
system can function properly.
A WARNING
- Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals ,
since they are not always detected by the
sensors.
- The acoust ic park ing system is not a sub­
st itute for the d river's own caut io n and
alertness . Ultimate responsib ility always
remains with the driver during park ing
and simi lar maneuvers. Always watch
where you are dr iving .
- You should always adjust the volume and
frequency of the warning tones so that
yo u can easily hear the a co ustic distance
warning even if the radio is p laying, the
air-conditioner blower is on High or there
is a high leve l of outside noise.
- Check the settings whenever anyone
else has driven the vehicle before you.
- Remember that low obstacles for wh ich
-
a war ning has a lready been issued may
"dive" below the system's sensing zone if
the veh icle is being backed up closer . In
th is case, the warn ing sound shutt ing off
does
not i ndi cate that you have cleared
the obs tacle. Instead, impact is immi­
nent .
- Objec ts such as trai ler hitches, c hains,
narrow posts or fences covered by a thin
l ayer of paint may not a lways be detect -
Park a ssis t 119
ed by the sys tem . They can still damage
your vehicle without warning.
(0 Tips
Keep the senso rs in the rear b umpe r clean
and free of snow and ice so that the acous­
tic parking assist system can function proper ly .

R ear view came ra co verage area
The MM I d isplay shows the area covered by
the rear view camera <=:>
fig. 133 (D . Objects
that are not in the area covered @are not
shown on the MMI display.
We recommend that you p ractice parking with
the rear view camera in a traffic -free location
or parking lot to become familiar with the sys ­
tem, the orientation lines, and their function.
When do ing th is, there shou ld be good light
and weather conditions.
In t he MMI disp lay, objects or vehicles appear
closer or further away if:
- yo u are driving in reverse gear from a level
surface onto an incline, or a downward
s lope,
- you are driving in reverse gear toward pro ­
truding objects,
- the vehicle is carrying too much load in the
rear .
The accuracy of the or ientat ion lines and blue
surfaces d imin ishes if:
- the rear view camera does not prov ide a reli­
able image, for examp le, in poor visibility
condit ions or if the lens is dirty,
- the image on the screen is not visible due to
sun g lare and reflect ion.
Caring for the rear view came ra lens
The rear view camera is located above the rear
license plate bracket . Fo r the parking assist to
operate, the lens <=:>
fig. 134 must be kept
clean:
- Dampen the lens with a household alcoho l­
based glass cleaner, and clean the lens with
a dry cloth <=:>
CD.
- Remove snow with a hand brush and ice
preferably with a de -icing spray

A WARNING
-The parking aid cannot replace the driv­
er's attent ion. The dr iver alone is respon­
sible for park ing and similar driving ma­
neuvers .
-Always keep your eyes on the vehicle 's
surroundings, us ing the rea r view m irror
as well.
- Do not allow yourself to be dist racted
from traffic by the rear view camera p ic­
tures.
- If the position and the installation angle
of the camera has changed, for examp le,
after a rear end collision, do not conti nue
to use the system for s afety re asons .
H ave it checked by a qualified dea le rship.
CJ) Note
- Low obstacles a lready s ignaled by a
wa rning can disappear from the system's
detect ion range as they are app ro ached
and w ill not continue to be signaled. Ob­
jects such as barrier chains, trailer d raw
bars, thin painted vertica l poles or fen­
ces may not be detected by the system,
posing risk of damage.
- Never use warm or hot water to remove
snow or ice from the rear view camera
lens -danger of crack format ion on the
lens!
- When cleaning the lens, never use prod­
ucts that are abrasive .
Switching on/off
Applies to vehicles: wit h parking system (rear, wit h rear
v iew camera)
The rear view camera switches on automati­
cally together with the acoustic pork assist when you put the vehicle in reverse.
Switching on
.,. Put the ve hicle in reverse gear, the acoust ic
parking system wi th rear view camera is ac ­
tivated a utomatica lly. Activation of the
acoust ic parking system is confirmed by a
brief acknowledgement sound . ..,_

122 Park ass is t
Sw it c hing off
.,. Drive faster than 9 mph (15 km/h), or
.,. take the vehicle out of reverse gear. The
acoustic parking system is immediately de ­
activated, and the rear view camera picture
is deactivated automatically after a per iod
of about 15 seconds, or
.,. switch off the ignition.
The delay in deactivating the camera provides an uninterrupted view behind the vehicle es­
pec ially when maneuvering in tight parking
spaces and prevents the picture from turning
off the every time you sh ift out of reverse .
If the warning message appears in the display but not the rear view camera picture, read and
confirm the warning message. The acoustic
d istance signal is always active .
If you press a function button on the MMI
control console, the rear view camera picture
d isappears. The rear view camera picture reap­
pears the next time you park.
Further information on the warn ing message
and the MMI control console can be found in
the MMI instruction booklet .
A WARNING
-Only use the rearview camera to assist
you if it shows a good, clea r picture. For
example, the image may be affected by
the sun sh in ing into the lens, dir t on the
lens or if there is a defect .
- Use the rearview camera only with the
rear lid completely closed. Make sure any
objects you may have mounted on the
rear lid do not block the rearview cam­
era .
(D Tips
-The rear v iew camera picture is ava ila b le
as soon as the MM I Display or the MM I is
switched on, or the start-up phase is
completed.
- The sensors must be kept clean and free
of snow and ice for the park assist to op­
erate. -

(!) Tips
The child seats listed in categories A to C have been statically tested by Audi on ly for
the Advanced A irbag function.
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially
reduces the risk of injury in an accident!
As the driver, you are responsib le for the safe­
ty of everybody in the veh icle, especially ch il­
dren:
... Always use the right ch ild safety seat for
each child and always use it properly
c::;,page 171 .
... Always carefully follow the child safety seat
manufacturer's instruct ions on how to route
the safety belt properly through the child
safety seat.
... When usi ng the veh icle safety belt to install
a child safety seat, you m ust first activate
the convertib le locking retractor on the
safety belt to prevent the child safety seat
from moving
¢ page 175.
... Push the ch ild safety seat down with your
full weight to get the safety belt really tight
so that the seat cannot move forwa rd or
sideways mo re than one inch (2.5 cm) .
... If a strap or tether is be ing used to t ie the
child safety seat to the front passenger
seat, make sure tha t it i s n ot so tight th at i t
causes the weight -sensing mat to measure
more weight than is act ually on the seat.
... Sec ure unused safety belts o n the rear seat

Electronic Stabilization
Control (ESC)
Description
ESC 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. ESC detects
certain difficult driv ing situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 185
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC 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 conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing t he vehicle under con­

ESC is switched on all the time. In certain sit­

The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up

the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles wi th adap tive c rui se control*, the
brake assis t system is more sensitive if the
