84 Description
Applies to vehicles: with Audi active lane assist
The active Lane assist uses a camera in the wind­
screen to detect Lane markings (subject to gener­
al system Limitations). If you approach one of the
detected lane markings, the system corrects the
steering to warn you that the vehicle might be
about to cross one of the markings. You can over­
ride this steering input at any time. The steering
wheel vibrates slightly if you cross a Lane mark­
ing. The vibration warning must be activated be­
forehand on the infotainment system. The active
Lane assist is functional when it detects a demar­
cation line on at least one side of the Lane in
which you are driving.

Indicator lamps
• Ready: The indicator Lamp Lights up when the
system is fully functional. The system is ready to
intervene .
• Not ready: The indicator Lamp Lights up when
the system is switched on but not ready to inter­
vene. The causes for this can include the follow­
ing:
- There are no Lane markings.
- The system cannot detect the relevant Lane
markings (e.g. temporary markings for road
works or markings obscured by snow, dirt, rain
or adverse Light).
- The vehicle's speed is below 65 km/h, the
speed at which the Lane assist system is activa­
ted (the threshold may vary in different export
markets).
- The Lane is narrower than 2.1 m or wider than
5.5 m.
- The bend is too tight.
- You have taken your hands off the steering
wheel.
@ Note
- Make sure that the camera window
¢ Fig. 92 is not covered with stickers or sim­
ilar objects. Notes on cleaning ¢ page 236.
- On vehicles for some export markets: once
the system is activated, it is "ready" each
time the ignition is switched on.

Driver messages on the infotainment display
Should the active lane assist be deactivated auto­
matically, the indicator lamp on the display will
go out and one of the following messages will
appear:
Audi active lane assist: currently unavailable.
Camera view restricted due to surroundings.
This message is displayed when the camera is no
longer functional after the system has continu­
ously failed to detect the lane markings. This can
have the following causes:
- The outside of the camera window¢ page 85,
Fig. 92 is dirty or frosted. Remove dirt or ice
from this area of the windscreen.
- The inside of the camera window is misted up.
In this case, wait for the camera window to de­
mist before switching on the active lane assist
system again.
- Due to the road conditions, the system has not
been able to detect the lane markings for a .,..

change. In all cases, the side assist will give
a warning for the vehicles it has detected at the
latest when they enter the "blind spot".
© Other vehicles being overtaken
When you are overtaking another vehicle slowly,
with a speed differential of less than 15 km/h,
the warning lamp in the exterior mirror will light
up as soon as the other vehicle enters your blind
spot.
If you are overtaking another vehicle quickly, with
a speed differential of more than 15 km/h, the
warning lamp will not light up.
System limitations
The radar sensors are designed for normal lane
widths and monitor the lanes immediately to the
left and right of your vehicle. In certain situations
the warning lamp on one of the exterior mirrors
may light up even if no vehicle is travelling in an
area that could be critical in the event of a lane
change. For example:
- When you are travelling in a narrow lane or
when you are not travelling in the centre of the
lane. In this case the system may monitor an­
other lane and register a vehicle that is not in
fact travelling in an adjacent lane.
- When you are driving into a bend. The side as­
sist may react to a vehicle two lanes away.
- If the system detects other objects (such as
crash barriers, etc).
- In poor weather conditions. The functionality of
the side assist is then restricted.
The radar sensors ¢ Fig. 98 must not be obstruc­
ted by stickers, bicycle racks, deposits or any oth­
er substances which could impair the function of
the system. For notes on cleaning, please refer to
¢page 236.
.&_ WARNING
-Always watch the road and the area sur­
rounding the vehicle. The side assist feature
is not a substitute for the full concentration
of the driver. The driver is always responsi­
ble for the safety of lane changes and other
manoeuvres. Driver
assist systems
- In certain situations, the system may not
function properly, or the functionality of the
system may be restricted. For example:
- If other vehicles are approaching very
qui ckly, or if you are overtaking other
vehicles quickly. The warning lamp may
not light up in time.
- In poor weather conditions, such as heavy
rain, snow or road spray.
- If you are travelling in very wide lanes, in
tight bends or over crests. The system may
not detect vehicles in the adjacent lane
because they are outside the area covered
by the sensors.
CD CAUTION
Impacts or damage to the bumper, wheel
arches or underbody can cause misalignment
of the sensors. This can impair the functional­
ity of the system. Have the systems checked
by a qualified workshop.

of accident!
«]} Note
You can drive on if the warning/indicator lamp

Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly re­
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicle is operated. Negative factors
are, for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises Brake noise may develop in certain situations, de­
pending on the speed, braking force and ambient
conditions (such as temperature and relative hu­
midity).
Effect of moisture and salt
In certain conditions, such as in heavy rain, or af­
ter washing the car or driving through water, the
full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. The
brakes should be "dried" by pressing the pedal to
restore full braking effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet con-
ditions. ..,..

106 Power
management
This system helps to ensure reliable
starting
The power management controls the distribu­
tion of electrical energy and thus helps to ensure
that
there
is always enough power available to
start the engine.
If a vehicle with a conventional electrical system
is left parked for a long time, the battery will
gradually lose its charge because certain electri­
cal equipment (such as the immobiliser) contin­
ues to draw current even when the ignition is off.
In some cases there may not be enough power
available to start the engine.
Your vehicle is equipped with an intelligent pow­
er management system to control the distribu­
tion of electrical energy. This significantly im­
proves reliability when starting the engine, and
also prolongs the life of the battery.
The main functions incorporated in the power
management system are battery diagnosis, re­
sidual current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the battery. Sensors detect
the battery voltage, battery current and battery
temperature. This enables the system to calcu­
late the current power level and charge condition
of the battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It con­
trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power level of the battery, the
individual electrical components are switched off
one after the other to prevent the battery from
losing too much charge and to ensure that the
engine can be started reliably.

.... Dynamic
power management
While the vehicle is moving, this function distrib­
utes the available power to the various electrical
components and systems according to their re­
quirements. 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 bat­
tery power Level.
ijJ Note
- The power management system is not able
to overcome the given physical Limits.
Please remember that the power and Life of
the battery are Limited.
- If the indicator Lamp ril c:> page 13 appears,
the starting ability may be impaired.
Points to remember
Starting ability has first priority.
Short trips, city traffic and Low temperatures all
place a heavy Load on the battery . In these condi­
tions 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 generated.
In these situations you will be aware that the
power management system is intervening to con­
trol 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 reliable starting even after a
Long period. Certain convenience features, such
as remote control unlocking, may not be availa­
ble. These functions will be restored when you
switch on the ignition and start the engine. Intelligent
technology
With the engine switched off
If you Listen to the radio or use other electrical
equipment when the engine is not running, this
will discharge the battery.
A message will appear on the infotainment dis­
play before the battery power drops to a Level
where the starting ability is impaired.
This message warns you that the system you are
using will soon be switched off automatically.
You should therefore start the engine if you wish
to continue using the system.
When the engine is running
Although the alternator generates electrical pow­
er, 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 sys­
tem will then temporarily shut off the electrical
components that are using a Lot of power, or re­
duce the current they are consuming. Heating
systems in particular use a Large amount of elec­
trical power. If you notice, for instance, that the
seat heating* or the rear window heater is not
working, they may have been temporarily switch­
ed off or regulated to a Lower heat output. These
systems will be available again as soon as suffi­
cient 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 alternator to meet the greater
power requirement and charge the battery at the
same time.
Information saved in the
control units
The vehicle is fitted in the factory with electronic
control units that, among other things, control
the engine and the gearbox. The control units al­
so monitor the exhaust system and the airbags.
The control units continually analyse data rele-
vant to the vehicle while you are driving. In the
