Parking 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, the acoustic park assist system is installed in
the rear of the vehicle=>
page 162.
The rear pa rk ing assist system uses ultrasonic sensors to determine
the distance of the vehicle from a detected obstacle. There are a tota l
o f f our sensors located on the rear bumper (two in the m iddle and
two on the sides) .
Parking system (rear, with rear-view cam era)*:
For the parking system (rear, with rear-view camera) , the rear
acoust ic park assist sys tem is integra ted in the rear of the vehicle and
the rear-v iew camera is integrated in the rear lid=>
page 166.
The parking system (rear, with rear-view camera) uses ultrasonic
sensors to determine the d istance of the vehicle from a detected
obstacle. There are a total of four sensors located on the rear bumper
(two in the m iddle a nd two on the sides). •

Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car .
Description
The rear acoust ic par king assist sys tem determines the d ista nce of
the vehicle from an obstacle using ultrason ic sensors . There are 4
sensors in the rear bumper .
T he range at which the sensors start to measure is
about :
To the side
Center rear
Act ivation 2
ft (0.60 m)
5
.2 ft (1.60 m)
Aco ust ic parking assist is act ivated automatically when
re ver se gear
is engaged . A b rief tone confirms that the system is activated .
Warning tones
Distance warning is given by chimes wh ich are generated by the rear
signa l generator . The vo lume and the pitch of the chimes can be
adjusted in the radio or i n the MM!*=>
page 163 .
Reversing
Distance warning when reversing starts when an obstacle is detected
in the range o f the pa rking assist system. As the d istance decreases,
the time interval between the audible tones becomes shorter .
When the distance is less than 1ft (0.30 m), the tone becomes
c ont inuous. At this point you should stop back ing up.

______________________________________________________ P_a _ r_ k_ a_ s_s _i _ s _t __ _
Please note that low objects already signaled by a warning can disap­
pear from the system's detection range and will not continue to be
signaled.
If the distance to an obstacle remains the same, the vo lume of the
distance warning is gradually reduced after about 4 seconds.
Approaching another obstacle will result in the distance warning
sounding at the normal volume again.
Malfunctions in the system
If a warning tone is aud ible for about five seconds when you turn on
the ignition , there is a malfunction in the system. Have the problem
corrected by your authorized Audi dealer.
Keep the sensors in the rear bumper clean and free from ice so that
the acoustic park assist system can function properly.
& WARNING
• Sensors have dead spaces in which objects cannot be detected.
Be especially alert for small children and animals, since they are
not always detected by the sensors.
• The Acoustic Parking System is not a substitute for the driver's
own caution and alertness. Ultimate respon sibility always
remains with the driver during parking and similar maneuvers.
Always watch where you are driving.
• You should always adjust the volume and frequency of the
chimes so that you can easily hear the acoustic distance warning
even if the radio is playing, the air-conditioner blower is on High
or there is a high level of outside noise .
- Check the settings whenever anyone else has driven the
vehicle before you.
0 Note
• Remember that low obstacles for which a warning has already
been issued may "dive" below the system 's sensing zone if the veh icle
is be ing backed up closer . In this case, the warning sound shutting off
Controls and equip ­
ment Safety first
does not ind
icate that you have cleared the obstacle . Instead, impact
is immin ent.
• Objects such as trai ler hitches, chains, narrow posts or fences
covered by a thin layer of paint may not always be detec ted by the
system . They can still damage your vehicle w ithout warning .
lI] Tips
Keep the sensors in the rear bumper clean and free of snow and ice so
that the aco ustic parking assist system can function properly.•

location of the rear­
view camera
Sensors are located in the front and rear bumpers. If these detect an
obstacle, audible and visual signals warn you. The range at which the
sensors begin to measure is approximately:
To the side
Center rear
2 ft (0.60 m)
5.2 ft (1.60 m)
The closer you get to the obstacle, the shorter the interval between
the audible signals. A continuous tone sounds when the obstacle is

OP-eration
less than approximately 1 foot (0.30 meters) away . Do not continue
driving farther.
If the distance to an obstacle stays the same, the volume of the
distance signal chime is gradually reduced after about
4 seconds
(does not affect the continuous signal tone). Approaching another
obstacle will cause the distance signal to sound again at the normal
volume.
Rearview camera coverage area
The MMI display shows the area covered by the rearview
camera ::> fig.
169 (D. Objects that are not in the area covered@ are
not shown on the MMI display.
We recommend that you practice parking with the rear-view camera
in a traffic-free location or parking lot to become familiar with the
system, the orientation lines, and their function. When doing this,
there should 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 protruding objects ,
• the vehicle is carrying too much load in the rear.
The accuracy of the orientation lines and blue surfaces diminishes if:
• the rear-view camera does not provide a reliable image, for
example, in poor visibility conditions or if the lens is dirty,
• the image on the screen is not visible due to sun glare and reflec ­
tion.
Caring for the rear-view camera lens
The rear-view camera is located above the rear license plate bracket.
For the parking assist to operate, the lens=> fig . 170 must be kept
clean:
• Dampen the lens with a household alcohol-based glass cleaner,
and clean the lens with a dry cloth=>

• two rollbars
• the safety belts with belt tensioners
• the windshield frame
• the rollover sensors
The active rollover protection system provides additional safety in the
event of a ro llover. Within milliseconds, sensors deploy two rollbars
located behind the headrests in the rear seats => fig. 182.
The rollbars, reinforced windshie ld frame and belt tensioners help
protect front and rear passengers in the event of a rollover .
The rollover protection system functions when the power top is both
open and closed.
& WARNING
Do not use the area behind the rear seat headrests=> fig. 181 as a
storage area. This is the area where the rollbars deploy. If the roll­
over protection system is triggered, objects placed there can be
propelled through the vehicle and make it more difficult for the
rollbars to deploy . This increases the risk for serious or life-threat­
ening injuries . •
When Is rollover protection deployed?
Rollover protection deploys in a collision or rollover.
Depending on the collision, sensors throughout the vehicle and the
control module trigger the rollover system to deploy.
For safety reasons, rollover protection also deploys during front, side
and rea r collisions above a certain level of severity .•

Advanced Airbag System components
Th e front passenger seat in your veh icle has a lot of very important
parts of t he A dvanced A irbag System in it. These parts incl ude t he
we ight-sens ing mat, sensors, wiring, brackets, and more. The func- tion of the system
in the front passenger seat is checked by the elec­
t ronic c ontro l unit w hen the ignitio n is o n. The contr ol unit mon itors
t he Advanced Airbag System and tu rns the airbag indicato r light o n
w hen a malfunction in t he system components is detected. The func­
t ion of the a irbag indicator light is descr ibed in greater deta il below .
Because the front passenge r seat co nta ins impo rtant parts of t he
Adva nced Ai rbag System, you must ta ke care to p reve nt i t from be ing
damaged. Damage to the seat may p revent the A dvanced A irbag for
t he fro nt passenge r se at from do ing its job in a crash.
The front Advanced Airbag System consists of the
following:
• Cras h sensors in the front of t he vehicle that measu re vehicle
a cc ele ration/de ce le ra tion to provi de i nfo rm ation to the Advanced
Airbag System about the severity of the crash .
• An e lec tron ic contro l unit, w it h i ntegrated crash sensors fo r front

& WARNING
(co ntinued )
• Never store item s under the front passenger seat . Parts of the
Advanced Airbag Sy stem under the passenger seat could be
damaged , preventing them and the airb ag system from working
properly .
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats .
• Seat cover s can prevent the Advanced Airbag System from
recognizing child re straints or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly .
• Never u se cushions, pillow s, blankets or similar items on the
front passenger seat. The additional padding will prevent the
weight-sensing mat in the seat from ac curately registering the
child restraint or person on the seat and prevent the Advanced
Ai rbag System from functioning properly .
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel, foam cushion or something else to properly position
the child restraint, make certain that the PASSENGER AIR BAG
OFF light comes on and stays on whenever the ch ild restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and

front a irb ags
Safety belts are important to he lp keep front seat occupants in the
pro per seated pos ition so that a irbags can unfold prope rly and
prov ide supp lemental protect ion in a frontal collision.
Th e front airbags are designed to provide add itio na l protec tion for
the c hest and face of the driver and the front sea t passenge r when:
• safety belts are worn properly ,
• t he seats have been posit ioned so that the occupant is prope rly
seated as far as possible from the airbag,
• and the head restraints have been properly adjusted .
Because air bags inflate in the b link of a n eye w it h great force, things
you have on your lap o r have place d on the seat cou ld become
dangerous projectiles, and be pushed into you if the a irbag inf lates .
When a n airbag dep loys, fine dust is released. This is normal and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powder used to l ubricate the ai rbags as they deploy.
It could irritate

I t is important to remember that while the supp lemental airbag
system is desig ned to reduce the li ke lihood of serious injur ies, other
injuries, for example swelling , b ruising and m inor abras ions, can also
