-Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake.
- Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
mJ illu­
minates and a driver message appears
¢ page 99 when the clutch is overload­
ed .
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
¢ page 212. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied .
0 Note
-S tronic- and tiptronic transmission:
When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear
is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling.
- S tronic- and tiptronic transmission: Al­
lowing the vehicle to roll when the en­
gine is stopped and the selector lever is in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv ­
er's safety belt is engaged in the buckle.
Transmission 97
Hill descent control
App lies to vehicles : wi th mult itronic/ S tro nic/tiptro nic
The hill descent control system assists the
driver when driving down declines .
Hill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de­ scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may still be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
¢ page 91 , hill descent control is also activat­
ed when the speed is set.
.&_ WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the brakes .

118 Park assist
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-

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.

Fig . 132 Parking mode 2: parallel park ing
Vehicles with the parking system are equipped
with a
rear view camera in addition to the
acoustic parking system.
You can choose between two modes to assist
you with parking. For example, you can use "parking mode
l" when parking in a parking
space or garage¢
fig. 131. When you want to
park parallel to the edge of the street, select
"parking mode 2"
¢ fig . 132.
The rear acoustic park assist system is inte­
grated in the rear of the vehicle and the rear
view camera is integrated in the rear lid
¢page 121 .
A WARNING
-The rear view camera has blind spots, in
wh ich objects cannot be detected. Be es­
pecially careful to check for small chil­
dren and animals before backing up.
Small chi ldren and animals wi ll not al­

Sensors in the bumper
Sensors are located in the rear bumpers. If
these detect an obstacle, audible signals warn
you. The range at which the sensors begin to measure is approximately:
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
parking assist system . As the d istance de­
creases, the time interval between the audible
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 .
If the distance to an obstacle stays the same,
the volume of the distance signal chime is
gradually reduced after about 4 seconds (does ..,.

volume.
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 <=:>

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

220 Check ing and filling
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure re lief valve in the cap when the en ­
g ine becomes hot.
A WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn
off the engine and a llow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a co unte r-clockwise d irection while
apply ing light, downward press ure on
the top of the cap.
- To avoid being burned, do not spi ll an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certa in
conditions, the ethylene glyco l in en­
g ine coolant can ca tch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its original container and we ll
o ut of the reac h of children.
- If you drain the coolant, it must be
caught and safely stored in a p roper con­
ta iner clear ly ma rked "poison".
(D Note
- Do not add coolant if the expansion tan k
i s empty. A ir could enter the cooling sys­
tem and damage the eng ine. If this is
the case, do not continue driving. Seek professional assistance.
- Coolant po llutes the e nv ironment and
could cause an engine fire. Excess coo l­
ant will be forced ou t through the pres ­
su re rel ief v alve in the ca p when the en­
gine becomes hot .
- If, in an emergen cy, only water can be
added, the correct ratio be twee n wa te r
and antifr eeze¢
page 218 must be re ­
stored as soon as possib le .
{® For the sake of the environment
D rained coo lant should not be reused . A l­
ways d ispose of used coolant whi le observ­
i ng a ll environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
T he rad iator fan is driven by the engine v ia the
V-belt. The viscous clutch regulates the spee d
of the fan acco rding to the temperature of the
coolant.
An a uxiliary electric radiator fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing condit ions .
A ft er yo u sw itch the eng ine

- even wit h the ignition
off. It can even switc h
on again later by itself¢.&. , if
- t he temper ature of the engine coo lant rises
due to the heat build -up from the engine in
the engine compa rtment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlig ht.
A WARNING ~
- To reduce the risk of perso na l inj ury nev -
er touch the radiator fan.
- The a uxiliary electric fan is tempe rat ure
contro lled and can sw itch on sud denly
even when the engine is not running.
- The a uxiliary radiator fan switches on a u­
