& WARNING
-Always take the vehicle key with you when
leaving the vehicle, even for a short period
of time. This a pplies particularly when chi l­
dren rema in in the vehicle . Ot herwise ch il­
dre n could star t the engi ne, release the
par kin g br ake o r o per ate ele ct rical e quip­
ment su ch as power win dows, whi ch in­
creases the risk of an acc ident .
- No one sho uld rem ain in t he vehicle when i t
is lo cked, es pec ially children. Locked doors
make it mo re diff icu lt fo r emergency work­
ers to get into the vehicle, which puts lives
at risk.
Starting from a stop
The start assist function ensures that the park ­
ing brake is released automatically upon start­
ing.
Stopping and setting the parking brake

Starting and automatically releasing the
parking brake
.,. When yo u press the accelerator pedal, the
par king b rake is autom atically rele ased and
yo ur vehicle begins to move.
T he parki ng b rake can be set if you must stop the
ve hicl e at a s to p lig ht or in t raff ic. Th e ve hicle
does not h ave to be he ld w ith the bra ke pedal.
T he parkin g brake e liminates the tendency to
creep when a selector lever position is engaged .
The parking b rake releases automatica lly and the
ve hicle beg ins to move as soon as you p ress the
accelerator pedal as usual.
Starting on slopes
W hen starting on inclines, the hill star t ass ist
p revents the ve hicle from unintentionally ro lli ng
back . The braking force of the park ing brake is
not released until sufficient d riving force has
been b uilt up at the w heels.

(D Tips
Fo r safety reasons, the par king brake is re­
l eased a utomatically on ly when the d river's
safety be lt is engaged in the b uck le.
Starting to drive with a trailer
To prevent rolling back unintentionally on an in ­
cline, do the following:
.,. Keep the switch pull ed ~ and press t he accel ­
erator pedal. The parking brake stays app lied
and prevents the veh icle from roll ing backward .
.,. You can release the switch ~ once yo u are su re
that you are transferring enough driving force
to the whee ls by press ing the accelerator pedal.
Depend ing on the weight of t he rig (vehicle and
trailer) and the sever ity of the incline, you may
r oll backwards as you sta rt .
Emergency braking function
This is used if the conventional brake system
fails or lock s up.
.,. To brake your veh icle in an eme rge ncy, pull the
~ switch and hold it pu lled .
.,. As soon as you re lease the~ switch or acceler-
ate, the braking stops .
If you p ull the switch
«v> and hold it above a
speed of about 5 mph (8 km/h), the emergency braking function is init iated. The vehicle is braked
at all fou r whee ls by activati ng the hydraulic
brake system . The brake performance is s imilar
to making an emergency stop~.&. .
In order not to activate the emergency braking by
mistake, an aud ible warn ing to ne (buzzer)
sou nds when the~ switch is pulled . As soon as
the ~ switch is re leased, or the accele rator peda l
i s dep ressed, eme rge ncy braking stops.
& WARNING

Engine does not switch off
Before and during each stop phase, the system
checks if certain conditions have been met. For
example, 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.

- The vehicle rolls, for example while on a slope.
- The interior temperature varies from the tem-
perature selected in the A/C system.
- The windshield is being defrosted®.
- The brake pedal is pressed several 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

A WARNING
Never allow the engine to run in confined
spaces, because this increases the risk of as­
phyxiation .
(D Tips
-If you shift into the D or N position after
shifting into reverse, the vehicle must be
driven faster than 6 mph (10 km/h) in order
for the engine to switch off again .

-
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 conditions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
r isk of an accident.
- Switch the cruise control off temporarily
when dr iving in turning lanes, highway exits
or in construction zones .
- Please note that unconsciously "resting"
your foot on the accelerator pedal prevents the cruise contro l from braking. This is due
to the control system being overridden by
the driver's acceleration.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off. The rest of
the cruise control system functions remain active as long as the indicator light

Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise contro l system assists the
driver by regulating vehicle speed and helping to
maintain a set distance to the veh icle ahead ,
within the limits of the system. If the system de­
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your vehi­
cle. This helps to make driving more comfortable
both on long highway stretches and in stop-and­
go traffic.
The braking guard system can warn you about an
impending collision and initiate braking maneu­
vers
c::> page 90.
Adaptive cruise control and braking guard have
technical limitations that you must know, so
please read this section carefully, understand
how the system works and use them properly at
all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 88 Front of the ve hicle: sensors and video camera
The areas that contain the radar and ultrasonic
sensors and the video camera
c::> fig. 88 must nev­
er be covered by stickers or othe r objects or ob­
structed with dirt, insects, snow or ice that will
interfere with the adaptive cruise control system
and braking guard. For information on cleaning,
84
refer to c::> page 203. The same applies for any
modifications made in the front area .
The function of the adaptive cruise control sys­
tem and braking guard is limited under some
conditions:
- Objects can only be detected when they are
w ithin sensor range
c::>page 86, fig. 91.
- Th e system has a limited ability to detect ob­
jects that are a short distance ahead, off to the
side of you r vehicle or moving into your lane .
- Some kinds of vehicles are hard to detect; for
example motorcycles, veh icles with high
ground clearance or overhanging loads may be
detected when it is too late or they may not be
detected at all.
- When driving through curves
c::> page 85.
-Stationary objects c::> page 85.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you. The driver must
always take act ion to avoid a collision . The
driver is always respons ible for braking at the
correct time.
- Improper use of adaptive cruise control can cause collisions , other accidents and serious
personal injury.
- Never let the comfort and convenience that
adapt ive cru ise control and braking guard
offe r dist ract you from the need to be alert
to traffic conditions and the need to remain
in fu ll contro l of your ve hicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will no t slow the vehicle down or maintain
the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a traff ic jam, a stalled or disab led vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a co llision warning and if confirmed by the
video camera, an acute co llision warning.

Audi ada pti ve c ruise contr ol and br akin g gu ard
-For safety reasons, do not use adapt ive
cruise contro l when driv ing on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing) . Us ing the system under these condi­
t ions could result in a collision .
- Switch adaptive cruise contro l off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in const ruc tion zones. This
preven ts the vehicle from accelerating to
the set speed when in these situat ions .
- T he adapt ive cr uise con trol system will no t
br ake by i tself if you pu t your foot on the ac­
celerator peda l. Doing so can override the
speed and distance regulation.
- Whe n approaching stat ionary obje cts such
as stopped traffic, adapt ive cruise control
will not respo nd and braking guard will have
limited function .
- The adaptive cruise control system and
brak ing guard do not react to peop le, ani­
ma ls, objects crossing the road or oncom ing
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rai ls, t he entrance to a tunnel, heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safely . The adap­
t ive cr uise control cannot slow or brake the
vehicle safely when you follow another veh i­
cle too close ly. Always remember th at the
au tom atic b raking function ca nnot br ing the
vehicle to a sudden or emergency stop un­
der these conditions .
- T o preven t unintended operation, alw ays
switch AC C off when i t is not be ing used.
(D Note
The sensors can be displaced by impacts o r
damage to the bumper, whee l housing and
underbody. That co uld affect the adaptive
cru ise con trol sys tem and braking guard .
Have your a uthorized Audi dea ler or author·
ized Aud i Service Facility check their function.
In curves
Applies to vehicles: w ith Audi adapt ive cruise control
F ig. 89 Exampl e: d ri ving into a curve
When driving into a curve¢ fig. 89 and out of a
curve, the adaptive cruise control may react to an
object in the neighboring lane and app ly the
brakes . Yo u can prevent that by pressing the ac­
ce le rator peda l br iefly.
Stationary objects
Applies to vehicles : w ith Audi adaptive cruise control
Fig. 90 Exa mple : object changing la nes a nd s tatio nary ob ·
j e ct
T he adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving. For example, it can
react when a vehicle that has already been de­
tected @ turns or changes lanes, but adaptive
cruise control does not react to a stationary veh i­
cle @.

Audi adaptive cruise
control
Description
Applies to vehicles: with Audi adaptive cruise control
F ig. 91 Detection range
What can adaptive cruise control do?
The adaptive cruise control system uses video, ra­
dar and ultrasound . Moving vehicles ahead can
be recognized up to about 650 feet (200 m)
away .
On open roads with no traffic, adaptive cru ise
control works like a regular cruise control sys­
tem. The stored speed is ma inta ined. When ap­
proaching a moving vehicle detected up ahead,
the adaptive cruise cont rol system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­ ously stored. As soon as the system does not de­
tect a vehicle up ahead, adaptive cruise control
accelerates back up to the stored speed.
In stop-and-go traffic, adaptive cruise control can
brake until the vehicle stops and accelerate again
under certain conditions and if this is possible
within the system's limits and capabilities
¢ page 88. Adaptive cruise control will not
make an emergency stop .
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 86, Switching on and off.
When driving, you can stop cruise control
¢ page 88 or change the speed ¢ page 8 7 at
any time.

You can also set the distance to the object ahead and set the adaptive cruise control driving pro­
gram
