Rear parking system
Rear acoustic park assist
App lies to veh icles : w ith pa rking system (rea r)
The rear acoustic pork assist warns you of obsta­
cles or objects behind your car.
Description
The rear acous tic p arking assist system de ter ­
mines t he d istance o f the veh icle from an obsta -
114
cle using ultrasonic sensors . There are 4 sensors
in the rear bumper.
The range at whi ch the sensors s tart to measure
i s
abou t:
To the s ide 2 ft (0 .60 m)
Cente r rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is act ivated automatically
whe n
revers e gear is engaged. A brief tone con­
firms that the system is a ctivated.
Warning tones
D istance warning is give n by warni ng tones wh ich
are generated by the rear signal generator . The
vo lume and the p itch of the warn ing tones can be
adjus ted in the M MI*
¢ page 115.
Rever sing
D istance warning when reversing starts when an
obstacle is detected in t he range of the parking
ass ist system . As the distance dec reases, the
time interva l between the audib le tones becomes
sho rter.
When the distance is less than 1ft (0 .30 m), the
tone becomes cont inuo us. At th is point you
shou ld stop backing up .
Please note that low objects already s ignalled by
a war ning can d isappear from the system's detec ­
tion range and wi ll not cont inue to be s ignalled .
If the distance to an obstacle remains the same,
the volume of the d istance warning is gradually
reduced after about 4 seconds (th is does not ap ­
ply i n the continous to ne range) . Approaching an­
othe r obstacle will result in the distance warn ing
sounding at the normal volume aga in.
Malfunctions in the system
If a warning tone is audible for about five sec­
o nds when you turn on the ignition, there is a
malfunction in the system . Have the prob lem
cor rected by you r authorized Audi dea le r.
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park ass ist sys -
tem can function properly . .,.

,&_ WARNING
-Sensors have dead spaces in which objects
cannot be detected. Be especia lly alert for
small children and animals, since they are not always detected by the sensors.
- The acoustic parking system is not a substi­
tute for the dr iver's own caution and alert­
ness. Ultimate respons ibility always remains
with the driver during parking and sim ilar
maneuvers . Always watch where you are
dr iv ing .
- You should always adjust the volume and
frequency of the warning tones so that you
can eas ily hea r the acoustic distance wa rn­
ing even if the radio is p lay ing, the air-cond i­
tioner blower is on High or there is a high
level of ou ts ide no ise .
- Check the settings whenever anyone e lse
has driven the vehicle before you.
(D Note
- Remember that low obstacles for which a
warning has already been issued may "dive"
below the system's sensing zone if the vehi­
cle is being backed up closer. In this case,
the war ning sound shutting off does
not in­
dicate that you have cleared the obstacle.
Instead, impact is imm inent.
- Objects such as tra iler hitches, chains, nar­
row posts or fences cove red by a th in laye r
of pa int may not always be detected by the
system. They can still damage your vehicle
wi thout warn ing.
{O) Tips
Keep the senso rs in the rear bumper clean
and free of snow and ice so that t he acous tic
parking assist sys tem can f unction properly.

Sensors in the bumper
Sensors are located in the rear bumpers . If these
detect an obstacle, audible s ignals warn you . The
range a t which t he sensors beg in to measu re is
approx ima tely:
To the side 2 ft (0.60
m)
Center rear 5.
2 ft (1.60 m)
Distance warning when reversing starts when an
obstacle is detected in the range of the pa rking
116
assist system. As the distan ce decreases, t he
time interval between the audib le tones becomes
sho rter.
When the distance is less than 1ft (0.30 m), the
tone becomes cont inuo us. At th is point you
shou ld stop backing up .
If the distance to an obstacle stays t he sa me, the
vo lume of the dis tan ce signal chime is g radua lly
reduced after a bout
4 seconds (does not a ffect
the continuous signal tone). Approaching anoth­
er obstacle will cause the distance s ignal to
sound again at the normal volume.
Rear view camera coverage area
The MMI display shows t he area cove red by the
rear view camera
¢fig . 132 (!). Objects that are
not in the a rea covered @are not shown on the
MMI display.
We recommend tha t you prac tic e parking wit h
the rear view camera in a traffic -free location or
parking lot to become familiar with the system,
the orientat ion lines, and their function. When
do ing this, there should be good light and weath­
er condit ions.
In the MMI display, objects or vehicles appear closer or further away if:
- you a re dr iv ing in reve rse gear from a level s ur­
face onto an incline, or a downward slope,
- you a re dr iving in reve rse gear tow ard prot rud­
ing objects,
- t he vehicle is car rying too much load in the
rear.
The acc uracy of the or ie ntation lines and blue
s ur faces dim inishes if:
- the rear v iew camera does not provide a reliab le
image, fo r example, in poor visib ility co ndi tions
or if the le ns is dirty,
- the image on the screen is not v isible due to
sun glare and reflectio n.
Caring fo r the rear v iew camera lens
The rear view camera is located above the rear li­
cense plate bracket. For the parking assist to op-
erate, the lens¢
fig. 133 must be kept clea n: .,..

A WARNING
- The parking aid cannot replace the driver's
attent ion. The driver a lone is responsible for
park ing and s imilar driving maneuvers.
-Always keep your eyes on the vehicle's sur­ round ings, using the rear view m irror as
we ll.
- Do not a llow yourse lf to be d istracted from
traff ic by the rear view camera p ictures.
- If the posit ion and the installat ion ang le of
the camera has changed, for example, after
a rear end collision, do not continue to use
the system for safety reasons. Have it
checked by a qualified dealersh ip .
@ Note
- Low obstacles already s ignaled by a warn ing
ca n disappear from the system's detection
range as they are approached and will not
continue to be signa led. Objects such as
barrier chai ns, t rai ler d raw ba rs, thin pa int ­
ed verti cal poles o r fences may not be de­
tec ted by t he sys tem, posing r isk o f dam­
age.
- Neve r use warm or hot water to remove
snow or ice from the rear view camera lens -
danger of crack format ion on t he lens!
- When cleaning the lens, never use p roduc ts
that are abrasive.

-To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the engine. If this is the case,
do not continue driving. Seek professional
assistance.
- Coolant pollutes the environment and could
cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
- If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
c::> page 208 must be restored as
soon as possible.
@) For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
belt . The viscous clutch regulates the speed of
the fan according to the temperature of the cool­
ant.
An auxiliary electric radiator fan* switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
Checking and Filling
with the ignition off. It can even switch on again
later by itself
c::> & , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.
