The parking aid cannot replace the full concentration of the
driver. The driver is always resp onsible for safety during parking
and other manoeuvres. Always k eep a close watch on the area
around the vehicle.
•
When parking or manoeuvring do not rely solely on the MMI
display. Some objects (e.g. narrow posts or bars) may - due to the
resolution of the display screen - not be displayed in a satisfactory
manner or may not be displayed at all.
Applies to vehicles: with parking system advancedNote on distances
The red line in the MMI display ⇒fig. 169 marks the distance which
you should keep to an obstacle wh en parking. If the obstacle is
located at road surface level you can approach the obstacle until the
red line (40 cm distance) makes contact with the obstacle. However,
if the obstacle is not at road surface level (e.g. the bumper of
another vehicle) you should not approach the obstacle allowing the
red line to make contact with the obstacle.
If you, for example, reverse towards a vehicle, the orientation lines
and area markings in the MMI displ ay appear to be overlapping onto
the vehicle behind ⇒ page 151, fig. 169. In the example shown in
the picture the red line in the MMI display is directly on the bumper
of the vehicle behind. In actual fact, however, the red line
⇒ page 151, fig. 170 is not making contact with the bumper but has
already moved underneath the bumper. The actual distance to the
vehicle behind (broken line ) is already much less than 40 cm. You
must also include the bumper of yo ur own vehicle in the calculation
of the distance ⇒.
WARNING
•
Please note that objects which are not touching the ground
may appear to be further away than they actually are (e.g. the
bumper of a parked vehicle, a towing bracket or the rear end of a
truck). In this case you should not use the orientation lines for
judging the distance (accident risk).
•
Please make sure you keep a sufficient distan ce 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).

Audi parking system
152Safety notesApplies to vehicles: with parking systemFault warning for the acoustic parking aidparking system:
If you hear a long beep when you engage reverse gear, the rear
parking aid is not functioning correctly.
parking system plus*/parking system advanced*:
If you hear a long beep for a few seconds when you engage reverse
gear and the diode in the switch
* starts flashing, there is a fault
in the rear and front parking system with graphic display.
You will be notified of a system fault
•
when you manually activate the parking system via the switch
* ⇒ page 138•
the first time you engage reverse gear after switching on the
ignition, or
•
immediately, if the fault is identified while you are using the
parking system.Note
If the system alerts you to a fault please have the fault rectified by
an Audi workshop or ot her qualified workshop.Applies to vehicles: with parking system advancedNotes on reversing cameraWe recommend that you practise parking with the reversing camera
in a quiet location (car park or similar) in order to become familiar
with the system, including the orientation lines and all the other
features. Ideally, the weather and light conditions should be good. Vehicles or other objects shown in
the MMI display appear to be
further away or closer, if:
•
you are reversing from a horizontal surface up a gradient or
down a hill,
•
you are reversing towards protruding objects,
•
the vehicle has been loaded with a greater load on the rear.
The accuracy of the orientation lines and the blue area markings
decreases if:
•
the reversing camera does not provide a reliable image, e.g. if
visibility is poor or the lens is dirty,
•
the sun is so dazzling that you cannot see the image on the
display screen.
How to clean the lens of the reversing camera:
•
Moisten the lens usin g a commercially available, alcohol-based
glass cleaning agent and clea n the lens with a dry cloth.
•
Remove snow using a small brush.
•
If possible, use de-icing spray to remove any ice ⇒.
WARNING
•
Even when using the reversing camera, the driver must still
keep a close watch on the area behind the vehicle and use the
mirrors.
•
For technical reasons, the reversing camera cannot show the
complete area behind the vehicle ⇒page 144, fig. 159. It is partic-
ularly 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 th em (accident risk).
•
The parking aid cannot replace the full concentration of the
driver. The driver is always resp onsible for safety during parking
and other manoeuvres . Always keep a close watch on the area
around the vehicle.

•
Do not allow the camera images in the MMI display to distract
you from watching the traffic.
•
When parking or manoeuvring do not rely solely on the MMI
display. Some objects (e.g. narrow posts or bars) may - due to the
resolution of the display screen - not be displayed in a satisfactory
manner or may not be displayed at all.
•
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).
•
If the MMI display is switched on and the picture is obscured or
the area behind the vehicle is no t visible (e.g. due to a dirty or
defective lens) you must not use the reversing camera to assist
you when manoeuvrin g (accident risk).
•
The reversing camera produc es two-dimensional images.
Please remember that ridges in the ground, parts protruding on
other vehicles or fixed objects jutting out are all more difficult to
detect on the MMI display screen du e to a lack of spatial depth. In
some cases it may not be possi ble to detect them at all.
•
For safety reasons, you should not use the system if the posi-
tion and installati on angle of the camera have been changed, e.g.
in a rear-end collision. Have it checked by a qualified workshop.
•
Only use the reversing camera wh en the boot lid is completely
closed. Please make sure that th ere are no objects mounted to the
rear end of the vehicle which could block the view of the reversing
camera.Caution
•
Never remove snow and ice from the lens of the reversing
camera using warm or hot water - da nger of cracks appearing on the
lens.
•
Never use abrasive cleaning agents on the lens.WARNING (continued)

Intelligent technology
196Intelligent technologyElectronic stabilisation program (ESP)General notes
The electronic stabilisation program increases the car's
stability on the road.The ESP is designed to enhance the control over the vehicle in crit-
ical handling situations, such as when accelerating and cornering.
It reduces the tendency to skid under all road conditions and
improves the stability and roadholding of the vehicle. The system
works at all speeds. The anti-lock brake system (ABS),
the electronic differential lock
(EDL) and the traction control system (ASR) are all integrated into
the electronic stabilisation program.
How the system works
The ESP control unit processes data from the three integrated
systems. It also processes addition al inputs provided by other high-
precision sensors. These register the vehicle's rotation about the
vertical axis (yaw rate), lateral acceleration, brake pressure and
steering wheel angle.
The system uses the steering wheel angle and road speed to calcu-
late the changes of direction intended by the driver, and constantly
compares them with the actual be haviour of the vehicle. If the
desired course is not being maintained (for instance, if the car is
starting to skid), then the ESP compensates automatically by
braking the appropriate wheel.
The forces acting on the braked wheel effectively bring the car back
to a stable condition. If the car is oversteering (rear wheels losing
grip first) the brake application is concentrated on the outside front
wheel; if the car is understeering (front wheels losing grip first), ESP
brakes the inside rear wheel. This automatic brake application is
accompanied by characteristic noises.
The ESP works in conj unction with the ABS ⇒page 197 . If a
malfunction should occur in the A BS, the ESP will also be out of
action.
Switching on
The ESP is switched on automatically when the engine is started
and performs a self-test routine. As soon as this routine is complete,
the system switches back to normal operating mode. You can press
the button ⇒fig. 203 or ⇒ fig. 204 to switch on the ESP or traction
control system (ASR) if they have been switched off. The message
ESP/ASR on will appear briefly in the display.

Switching off
The ESP should normally be left switched on at all times. If required,
you can press the ESP OFF button to switch off the traction control
system (ASR) or the electronic stabilisation program (ESP).
•
Switching off the traction control system (ASR):
Press the ESP
button briefly. The traction control system (ASR) can be switched off
in special driving conditions, e.g. if you are driving with snow chains
⇒ page 198 . The message ASR off will appear in the display.
•
Switching off the ESP/traction control system (ASR): Press the
ESP button for longer than 3 seconds. The ESP/ASR warning lamp
lights up when the system is switched off, see ⇒page 16 . The
message ESP switched off will appear in the display.
WARNING
•
The ESP is not able to overcome th e physical limits of adhesion.
Even with ESP, you sh ould always adjust your speed to suit the
conditions. Please bear this in mind, especially on wet or slippery
road surfaces. Do not let the extr a safety provided tempt you into
taking any risks when drivin g – this can cause accidents.
•
Please note that, when the ESP or ESP/traction control system
(ASR) is switched off, the driven wheels may start to spin, causing
the vehicle to lose grip, in part icular on slippery or wet roads -
danger of skidding!
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.The anti-lock brake system (ABS) is an important part of the car's
active safety system. However, the ABS will not necessarily guar-
antee shorter stopping distances in all conditions. For instance, on
loose gravel or fresh snow on top of an icy surface (conditions which
anyway require extreme care and reduced speed), the stopping
distance with ABS may even be slightly longer. How the ABS works
The system runs an automatic self-check when the car reaches a
road speed of about 6 km/h. This may be accompanied by a noise
from the ABS pump.
If one of the wheels is turning too slowly in relation to the road
speed, and is close to locking up, the system will reduce the pres-
sure in the brake line to this wheel. The driver is made aware of this
control process by a
pulsating of the brake pedal and accompa-
nying noise. This is a deliberate warning to the driver that one or
more of the wheels is tending to lock up and the ABS control func-
tion has intervened. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application
- do not “pump” the brake pedal.
WARNING
The grip provided by ABS is still su bject to the physical limits of
adhesion. Always bear this in mind, especially on wet or slippery
roads. If you notice that the AB S is working (to counteract locked
wheels under braking), you should reduce speed immediately to
suit the road and traffic conditio ns. Do not let the extra safety
provided tempt you into taking an y risks when driving – this can
cause accidents.
Note
If a malfunction should occur in the ABS, this is indicated by a
warning lamp ⇒page 18 .Brake assist system
The brake assist system helps the driver to achieve
optimum braking effect.The brake assist system helps to increase braking power and thus to
achieve a shorter stopping distance . If the driver presses the brake

198pedal very quickly, the brake assist system automatically boosts the
braking force to the maximum level, up to the point where the anti-
lock brake function (ABS) intervenes to stop the wheels from
locking. You should then keep the brake pedal pressed until the
vehicle has braked to the required speed. The brake assist system
switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunc-
tion in the ABS.
WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow too close behind the vehicle in front of you. An increased
accident risk cannot be compensated even by the brake assist
system, so always be sure to maintain a safe speed.Traction control system (ASR)
The traction control system prevents the driven wheels
from spinning when the car is accelerating.General notes
The traction control system (ASR) is one of the functions incorpo-
rated in the electronic stabilisation program (ESP).
The traction control system (ASR) helps the car to start moving,
accelerate and climb a gradient in slippery conditions where this
may otherwise be difficult or even impossible.
How the system works
The ASR acts automatically i.e. without the driver's intervention.
With the aid of the ABS sensors ⇒page 197 , the ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
power is reduced automatically to match the amount of grip avail-
able. The system works at all speeds. The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Switching on
The ESP is switched on automatically when the engine is started
and performs a self-test routine. As soon as this routine is complete,
the system switches back to normal operating mode. If the traction
control system (ASR) has been deactivated (for one of the reasons
noted below) you can switch it back on manually by pressing the
switch
⇒page 196, fig. 203. The message ESP/ASR on will appear
briefly in the display. If the traction control system (ASR) has been
deactivated, it will switch back on automatically at a speed of about
70 km/h on vehicles with front-wheel drive.
You can switch the traction control system (ASR) on again if neces-
sary by pressing the switch ⇒page 196, fig. 203.
Switching off
If required, the ASR can also be switched off manually by pressing
the switch briefly ⇒page 196, fig. 203 (for less than 3 seconds). The
ESP warning lamp lights up when the traction control system (ASR)
is switched off, see ⇒page 16 . The message ASR off will appear in
the display. For safety reasons, the system can only be switched off
at speeds below 50 km/h on vehicl es with front-wheel drive. The
ASR can be deactivated at any speed on vehicles with four-wheel
drive.
The traction control system should normally remain switched on at
all times. It should only be switched off manually in particular
circumstances where a certain amount of wheel slip may be desir-
able. For example:
•
when driving with snow chains
•
when driving in deep snow or on loose surfaces
•
when rocking the car backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as
possible.

Dynamic power management
While the vehicle is moving, this function distributes the available
power to the various electrical components and systems according
to their requirements. The power management ensures that on-
board systems do not consume more electrical power than the
alternator can supply, and thus
maintains the maximum possible
battery power level.
Note
•
The power management system is not able to overcome the
given physical limits. Please reme mber that the power and life of
the battery are limited.
•
A warning message will appear ⇒page 204, “Driver message in
the instrument cluster display” if the battery power has dropped to
a level where reliable starting is impaired.
Points to remember
Starting ability has first priority.Short trips, city traffic and low te mperatures all place a heavy load
on the battery. In these conditions a large amount of power is
consumed, but only a small amount is supplied. The situation is also
critical if electrical equipment is in use when the engine is not
running. In this case power is consumed when none is being gener-
ated.
In these situations you will be aware that the power management
system is intervening to control the distribution of electrical power.
When the vehicle is parked for long periods
If you do not drive your vehicle for a period of several days or weeks,
the power management will gradually shut off the on-board
systems one by one, or reduce the amount of current they are using.
This limits the amount of power consumed and helps to ensure reli-
able starting even after a long period. Please note that certain convenience features, such as the Audi
advanced key*, the remote control key or the electrical seat adjust-
ment may not be available when yo
u unlock the vehicle. These func-
tions will be restored when you switch on the ignition and start the
engine.
With the engine switched off
If you listen to the radio or us e the other MMI functions when the
engine is not running, this will discharge the battery.
The MMI display will show this wa rning message before the battery
power drops to a level where the starting ability is impaired.
Please start engine, otherwise system will switch off
in 3 minutes.
This message warns you that the system you are using will be
switched off automatically after 3 minutes. You should therefore
start the engine if you wish to continue using the system.
When the engine is running
Although the alternator generates electrical power, the battery can
still become discharged while the vehicle is being driven. This can
occur when a lot of power is being consumed but only a small
amount supplied, especially if the battery is not fully charged
initially.
To restore the necessary energy balance, the system will then
temporarily shut off the electrical components that are using a lot
of power, or reduce the current they are consuming. Heating
systems in particular use a large am ount of electrical power. If you
notice, for instance, that the seat heating* or the rear window
heater is not working, they may have been temporarily switched off
or regulated to a lower heat output. These systems will be available
again as soon as sufficient electrical power is available.
You may also notice that the engine runs at a slightly faster idling
speed. This is quite normal, and no cause for concern. The increased
idling speed allows the alternat or to meet the greater power
requirement and charge the battery at the same time.

204Driver message in the instrument cluster displayIf battery power drops to a level at which you may encounter prob-
lems when starting the engine, the following message will appear
in the instrument cluster display:
 Low battery charge: Battery will be charged while driving
This message reminds you that th e starting reliability may be
impaired. The message will disappear as soon as you set off and the
battery is charged.
Message comes on and goes out again
If the message appears in the displ ay after the ignition is switched
on or while driving, and goes out again after a period of time, the
battery has been charged up again sufficiently while the vehicle was
being driven.
Message comes on and does not go out
If the message appears in the displ ay after the ignition is switched
on or while driving, and does not go out again, the battery is not
being maintained at the proper power level. Starting reliability may
be impaired. You should have the battery checked by a qualified
workshop as soon as possible.
