Description
Applies to vehicles: with Sta rt-Stop-System
The Start-Stop-System can he lp increase fue l
economy and red uce CO2 emissions.
I n Start -Stop mode, the eng ine shuts
off auto ­
matica lly w hen the vehicle is stopped, such as at
a traffic light. The ign ition remains sw itched on
during this stop phase . The engine w ill restart
automatically when needed .
The Start-Stop-System is automatically activated
each time you switch on the ignition.
Basic requirements for Start -Stop mode
- T he driver's door is closed.
- T he driver' seat be lt is lat ched .
- The hood is closed .
- The vehicle must have been dr iven faster than
2.5 mph (4 km/h) s ince the last stop.

Engine does not switch off
Before and during each stop phase, the system
checks if certain conditions have been met . For
examp le, the engine will not switch off in the fol­
lowing situations:
- The engine has not reached the minimum re­
quired temperature for Start-Stop mode.
- The interior temperature selected by the A/C
system has not been reached.
- The outside temperature is extremely high/low.
- The windshield is being defrosted@.
- The parking system* is be switched on .
- The battery charge level is too low .
- The steering wheel is turned at a sharp angle or
is moving .
- After engaging the reverse gear.
- On sharp inclines.

play.
Engine automatically restarts
The standard Start-Stop mode will be canceled
during a stop phase in the following situations .
The engine restarts without any action by the driver.
Driving
- The vehicle rolls, for examp le while on a s lope.
- The interior temperature varies from the tem-
perature selected in the A/C system.
- The windshield is being defrosted@.
- The brake pedal is pressed severa l times in a
row.
- The battery charge level becomes too low.
- High power consumption.
The engine can turn off again when the condi­ tions for Start-Stop mode are met.
Ignition is switched off automatically
To prevent the battery from draining, the igni­
tion
will switch off automatically under the fol­
lowing conditions:
- The vehicle has already been driven.
- The Start-Stop-System has stopped the engine.
- The driver's door is opened .
- The driver's safety belt is removed.
- The brake pedal is not pressed down.
- The vehicle is stationary.
In this case, the activated low beam is replaced
by the parking light. The parking lights will
switch off after approximately 30 minutes or
when you lock the vehicle.
If the Start-Stop-System has not turned off the
engine or if you have switched the Start-Stop­
System off manually, the ignition will not be au­
tomatically switched off and the engine will con­
tinue to run

Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed .
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You w ill hear a warning tone when your speed ex ­
ceeds the sto red val ue by app rox imately 3 mph
(3 km/h) . An indicator light . (USA mode ls)/ .
(Ca nada models) in the ins trumen t cluste r dis­
play a lso turns o n at the same time. The ind ic a tor
li ght .,. turns off w hen the speed decrea ses
below the stored maximum speed.
Set ting a t hreshol d is recom mended if you would
lik e to be rem inded when you re ach a cert ain
maximum speed . Si tua tions where you may want
to do so include drivin g in a country w ith a gene r­
a l speed limit or if there is a specified max imum
speed for winter tires.
(D Tips
Eve n though your vehicle is eq uipped w ith a
speed warning system, you should still watch
the speedometer to make sure yo u are not
drivi ng faster than the speed lim it.

Dr ivi ng
and the distance between your vehicle and
other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road cond itions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
risk of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway ex its
or in construction zones.
- Please note that unconsciously "resting" your foot on the accele rator pedal p revents
the cruise control from braki ng. This is d ue
to the contro l system being over ridden by
the dr iver's acceler ation.
- I f a brake system malfunction such as over­
hea ting occurs when the cruise cont ro l sys­
tem is swit ched on, the braking f unction in
the system may be switched off. The rest o f
the cruise co ntrol system f unctions remain

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 99 Instrument cluster : approach warning
Braking guard uses radar sensors and a video
camera. It also functions within the lim its of the
system when adaptive cruise control is sw itched
off.
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own veh icle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slow ly . Braking guard does not react if it
cannot de te ct the situation .
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If the
vehicle ahead brakes sharply, you will not be
able to avo id a collision. The indicator light.
in the d isplay comes on .
- The
approach warning is g iven when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be pos­
sible to
avoid a co llis ion by swerving or braking
sharp ly. The indicator light. and indica tor in
the display will warn yo u about the danger
¢
fig. 99. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
M N by braking. <( I.J "". rl I.O
"' N <.0 ll This is not a vailable in some coun tri es. rl
- If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake with increasing force within
the limits of the system. This reduces the vehi­
cle speed in the event of a collision.
- The system can initiate maximum braking
short ly before a collision
1l . Full dece leration at
high speeds occurs only in vehicles with adap­
tive cruise control and s ide ass ist (pre sense
plus).
- If the braking guard senses that you are not
braking hard enough when a collis ion is imm i­
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imm inent ¢
page 185 .
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 92, Settings in the Infotainment sys­
tem .
A WARNING
--
Lack of attention can cause collisions, other
accidents and ser ious personal injuri es. The
braking guard is an ass ist system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always respon­
sib le for braking at the correct time.
- Always pay close attent ion to traffic,
even
when the braking guard is switched on . Be
ready to intervene and be ready to take com­
p lete control whenever necessary. Always
keep the safe and legal distance between
your veh icle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
example when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
-Always remember that the radar sensor for
the braking gua rd works on ly w ithin defined

Audi active lane assist
Audi active lane assist Lane assist
Description
A pp lies to veh icles: w ith Audi active lane assist
Active lane assist detects lane marker lines with­
in the limits of the system using a camera in the
windshield. If you are approaching a detected lane marker line and it appears likely that you
will leave the lane, the system will warn you with
corrective steering. You can override this steering
at any time. If you pass over a line, the steering
wheel will vibrate lightly. In order for this warn­
ing vibration to occur, it must first be switched
on in the Infotainment system. Active lane assist is operable when the lane marker line is detected
on at least one side of the vehicle.
The system is designed for driving on freeways
and expanded highways and thus works only at
speeds of 40 mph (65 km/h) or more .
Applies to vehicles with side assist*: If you acti­
vate a turn s ignal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there will be noticeable corrective steer­
ing shortly before you leave the lane. This will at­
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist*: the sys­
tem does not warn when it is ready if you activate
the turn signal before crossing the lane marker line. In this case, it assumes that you are chang­
ing lanes intentionally.
Applies to vehicles with adaptive cruise control*
or parking aid*: The corrective steering is target­
ed based on the driving situation. In addition to
the lane marker lines, the system can also take
into account other objects such as guard rails. If
they are detected in close proximity to the vehi­
cle, active lane assist helps prevent the vehicle
from driving too close to them. There is also
passing assistance . The system does not provide
any corrective steering if it detects that you are
passing another vehicle.
94
A WARNING
-
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in the lane, but it does not drive by itself. Al­
ways keep your hands on the steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi­
bly be identified unintentionally as lane marker lines. As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. This can result in active lane assist
not detecting the lane marker lines or de­
tecting them incorrectly.
- Under certain conditions such as ruts in the
road, a banked roadway or crosswinds, the
corrective steering alone may not be enough
to keep the vehicle in the middle of the lane.
- For safety reasons, active lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
potential for hydroplaning. Using active lane
assist under these conditions may increase
the risk of a crash.
