off.
WARNING
The intelligent technology in Audi hold assist cannot defy the laws
of physics. Do not let the extra convenience provided by Audi hold
assist tempt you into taking a safety risk.•
Audi hold assist cannot keep the vehicle stationary in all condi-
tions on a gradient (e.g. if the road is slippery or icy).
•
Audi hold assist must be swit ched on again each time the
engine is started – Risk of accident!
•
Never get out of the vehicle wh en the engine is running and
Audi hold assist is switched on – Risk of accident!
•
Always ensure that the vehicle is stopped properly and safely
to avoid injury to yourself and others.Caution
Switch off the Audi hold assist function before driving the vehicle
into a car wash.
Note
•
Audi hold assist can be switched on only when the driver's door
is closed, the driver's seat belt is buckled and the engine is running.
•
Audi hold assist prevents auto matic vehicles from creeping
forwards when the brake pedal is released with the car in gear.
•
When the vehicle has been stationary for an extended period,
Audi hold assist will automatically apply the parking brake. In this
case, the green symbol
 in the instrument cluster display will
change to red

On level ground it is sufficient to move the selector lever to P. On a
gradient the parking brake should be applied first and the selector
lever should be moved to P. This reduces the load on the locking
mechanism and makes it easier to move the selector lever out of
position P.
Vehicles with multitronic® gearbox: Your vehicle is equipped with
the hill hold assist function which makes it easier to drive away on
a slope. The system is activated when you press and hold the brake
pedal for a few seconds . When you release the brake pedal the
braking force will be maintained for a moment in order to prevent
the vehicle rolling back when you drive away.

•
Do not press the accelerator while selecting a gear with the
vehicle stationary and the engine running, as this could cause an
accident.
•
Please note that some power will still be transmitted when you
stop temporarily with the selector lever in position D, S or R. For this reason, to avoid ri
sking an accident, appl y the footbrake firmly

Parking aidApplies to vehicles: with Audi parking system/plus/advancedGeneral notesVarious systems are available to help you when parking or manoeu-
vring in tight spaces, depending on the equipment fitted on your
vehicle.
The Audi parking system gives an acoustic warning if there are any
obstacles behind the car ⇒page 169 .
When you are parking, the Audi parking system plus warns you
acoustically and optically about obstacles in front of and behind the
vehicle ⇒page 170 .
In conjunction with a reversing camera, the Audi parking system
advanced shows a picture of the area behind the vehicle. This
picture helps you to manoevre the vehicle backwards and sideways.
In addition, you are assisted by the acoustic signals and graphic
display of the parking aid ⇒page 171 .
Note
To ensure that the acoustic parking aid works properly, the sensors
must be kept clean and free of snow and ice.Audi parking systemApplies to vehicles: with Audi parking systemDescription
The Audi parking system is an acoustic parking aid.Sensors are located in the rear bumper. When the sensors detect an
obstacle, you are alerted by acoust ic signals (beeps). The measuring
range of the sensors starts at about: The acoustic signals sound with increasing frequency as you
approach the obstacle. A warning tone will sound continuously
when the vehicle is less than appr
ox. 0.30 m away from the obstacle.
Stop reversing immediately!
The volume of the warning beeps will be gradually reduced after
about 4 seconds if the vehicle remains at a constant distance from
a detected obstacle (it will not be reduced if the obstacle is closer
than 0.30 m).
The parking aid is switched on automatically when reverse gear is
engaged. You will hear a brief acknowledgement tone.
WARNING
•
The parking aid cannot replace the full concentration of the
driver. The driver is always resp onsible for safety during parking
and other manoeuvres.
•
The sensors have blind spots in which obstacles are not regis-
tered. It is particular ly important to ensure that there are no small
children or animals near the vehicle, as the sensors may not
always be able to detect them.
•
Always keep a close watch on the area around the vehicle and
make full use of the rear-view mirrors.Caution
Please note that low obstacles detected by the system may no
longer be registered by the sensors as the car moves closer, so the
system will not give any further warning. Certain kinds of obstacles
(such as wire fences, chains, thin painted posts or trailer draw bars, Rear

Only use the reversing camera to assist you if it is supplying
you with a good and clear picture. The quality of the picture could
be impaired by adverse light, dirt on the lens or a defect (accident
risk).
•
Only use the reversing camera when the boot lid is completely
c lo s e d . P l e a se m a k e su re t h a t t h ere are no objects mounted to the
rear end of the vehicle which coul d block the view of the reversing
camera.Note
•
If your vehicle is near an obstacle, the graphic display will also
appear in the reversing camera image. This superimposed graphic
helps the driver to localise the critical area of the vehicle.
•
You can change the display and adjust the volume and pitch of
the beeps ⇒ page 177.
•
Please refer to the notes on towing ⇒ page 177.

There is a slight delay in the picture display.
Applies to vehicles: with Audi parking system advancedParking perpendicular to the roadside
Parking mode 1 can be used when parking your vehicle in
a garage or parking bay.– Turn the steering wheel until the orange orientation lines
are pointing towards the parking space ⇒fig. 192.
You can estimate the distance to an obstacle by referring
to the markings . Each marking is equivalent to
1metre.

WARNING
•
The reversing camera does not show the complete area behind
the vehicle. It is part icularly important to ensure that there are no
small children or animals near the vehicle, as the reversing camera
may not always be able to detect them (accident risk).
•
Please note that objects whi ch are not touching the ground
may appear to be further away th an they actually are (e.g. the
bumper of a parked ve hicle, a towing bracket or the rear end of a
truck). In this case you should not use the orientation lines as a
guide when parking the car - accident risk!Caution
The MMI display shows the path of th e rear end of the vehicle if you
were to reverse using the current steering angle. NB: The front end
of the vehicle swings out further th an the rear. Please make sure you
keep a sufficient distance between the vehicle and any obstacles to
make sure that the exterior mirror or edge of the vehicle do not
collide with the obstacle (accident risk).

WARNING
•
When applying the brakes to clean off deposits on the pads and
discs, select a clear, dry road. Be sure not to inconvenience or
endanger other road users; do not risk an accident.
•
Never let the car coast with the engine switched off (this can
cause accidents).Caution
•
Never let the brakes “drag” by leaving your foot on the pedal
when you do not really intend to brake. This overheats the brakes,
resulting in longer stopping distances and greater wear.
•
Before driving down a long, steep gradient, it is advisable to
reduce speed and move the selector lever to a lower gear. In this
way you will make use of the engine braking effect and relieve the
load on the brakes. If you still have to use the brakes, it is better to
brake firmly at intervals than to apply the brakes continuously.Note
•
If the brake servo is out of action due to a malfunction, or if the
car has to be towed, you will have to press the brake pedal consid-
erably harder to make up for the lack of servo assistance.
•
If you wish to equip the car with accessories such as a front
spoiler or wheel covers, it is impo rtant that the flow of air to the
front wheels is not obstructed, otherwise the brakes can overheat.
Power steering (servotronic)The power steering assists th e driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed
to turn the steering wheel. The degree of power assistance is
adapted electronically , depending on the speed. If a fault should occur in the
servotronic system the power steering
will still operate. The degree of power assistance will, however, no
longer adapt to different speeds. If the electronic regulating system
is not working properly, this is most noticeable when turning the
steering wheel at low speeds (for instance when parking) – more
effort will be required than usual. The fault should be corrected by
a qualified workshop as soon as possible.
The power steering does not function when the engine is switched
off. In this case the steering wheel is very hard to turn.
If the steering is held at its turning limit when the car is stationary,
this will place an excessive load on the power steering system. In
this case, the power steering system will make noises. It will also
reduce the idling speed of the engine.
Caution
Do not keep the steering in the full-lock position for longer than
15 seconds when the engine is running – this could cause damage
to the power steering system.
Note
•
If the power steering should fail at any time or the engine is
switched off (for instance when being towed), the car can still be
steered. However, more effort will be required to turn the steering
wheel.
•
If the system is leaking or malfunctioning, please take the car to
a qualified workshop as soon as possible.
•
The power steering requires a special hydraulic fluid. The fluid
reservoir is located at the front of the engine compartment on the
left ⇒page 256 . The correct fluid level in the reservoir is important
for the power steering to function properly. The hydraulic fluid level
is checked at the Inspection Service.
