- Always keep in m ind that after several
brake applicat ions, you will need greater
pressure on the brake pedal to stop your
vehicle . Do not rely on stra ined brakes to
respond w ith maximum stopp ing power
in critical situations. You must allow for
increased bra king distances . The extra
distance used up by fading brakes could
lead to an accident .

a irbags, pretensioners) and illuminates for a
few seconds each time you switch the ignition
on.
I f the
II (USA mode ls)/ S,I (Canada models)
indicator light does not go out, or if it illumi­
nates while you are driving, or if it starts to
blink, then there is a ma lfunction somewhere
in the system.
If the light does not illuminate
when you switch the ignition on, this also means there is a malfunction.
A WARNING
If you have a malfunction in the safety sys­
tems, contact your author ized Audi dealer
immediate ly. Otherwise the safety sys­
tems may not wo rk properly in an acci­
dent.
& Central indicator light
I f the indicator light . or II turns on, check
the message in the instrument cluster.

If the J,.J indicator light blinks wh ile driving,
the ESC or ASR (Ant i- S lip Regulation) is active ­
ly regulating .
If the
Ji! indicator light turns on, the system
has sw itched the ESC off. In this case, you can
switch the ignition off and then on to switch
the ESC on again . The indicator light turns off
when the system is functioning fully .
If the

- Garment hooks on the sides of the pillars in
the rear of the vehicle and in the rear grab
handles
- Compartment in the rear center armrest
- Storage in the trim panels in the luggage
compartment
~ WARNING
-
- Always remove objects from the instru­
ment panel. Any items not stored could
slide around inside the vehicle while driv­
ing or when accelerating or when apply­
ing the brakes or when driving around a
corner.
- When you are driving make sure that
anything you may have placed in the cen­
ter console or other storage locations
cannot fall out into the footwells. In case
of sudden braking you would not be able
to brake or accelerate.
-Always keep the lid of the compartment
for (sun)glasses* closed while driving to
reduce the risk of injury during a sudden
braking maneuver or in the event of an
accident.
- Any articles of clothing that you have
hung up must not interfere with the driv­
er's view. The coat hooks are designed
only for lightweight clothing. Never hang
any clothing with hard, pointed or heavy
objects in the pockets on the coat hooks.
During sudden braking or in an accident -
especially
If the airbag is deployed -
these objects could injure any passen­
gers inside the vehicle.
- To reduce the risk of personal injury in an
accident or sudden stop, always keep the
glove compartment closed while driving.
- Read and follow all WARNINGS
~ page 160, Important safety instruc­
tions on the side airbag system.
-Hang clothes in such a way that they do
not impair the driver's vision.
- The coat hooks must only be used for
lightweight clothing. Do not leave any
heavy or sharp edged objects in the pock- ets which may interfere with the side cur­
tain airbag deployment and can cause
personal
injury in a crash.
- Do not use coat hangers for hanging
clothing on the coat hooks as this can in­
terfere with proper deployment of the side curtain airbags in an accident.
- Do not hang heavy objects on the coat
hooks, as they could cause personal in­
jury in a sudden stop.

Your vehicle is equipped with an electrome­
chanica l parking brake. The parking brake is
designed to prevent the vehicle from rolling
unintentionally and replaces the hand brake.
I n addition to the normal functions of a tradi­
tional hand brake , the electromechan ical
parking brake provides various convenience
and safety functions.
When starting from rest
-The integral starting assist helps you when
driving by automatically releasing the park­
ing brake ¢ page 78, Starting from rest .
- When starting on inclines, the starting as-
"' r-1 sist prevents the vehicle from unintentional-a::
~ Ly rolling back. The braking force of the

- For safety reasons, the cruise control
should not be used in the city, in stop­ and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light

82 Audi ad apti ve cruise contr ol a nd bra king gu ard
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the v ideo camera, an acute col­
lis ion warn ing .
- For safety reasons, do not use adaptive
cruise co ntrol when driving 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) . Using the system under
these cond it ions cou ld result in a co lli ­
sion .
- Swi tch adap tive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerat ing to the set speed when in these
situations.
- The adapt ive cruise control system wi ll
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation .
- When approaching stationary objects such as stopped traff ic, adaptive cruise
co ntrol will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
imals, objects c rossing the road or on­
coming objects .
- The function of the radar senso rs can be
affected by reflective objects such as
guard rai ls , the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise contro l canno t slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot br ing the vehicle to a
sudden or emergency stop under these condit ions.
- To prevent unintended operation, always switch ACC off when it is not being used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive

When approaching a moving vehicle up ahead,
the adaptive cruise control system automati­
cally brakes to match that object's speed and
then maintains the stored distance. If the ve­
h icle ahead accelerates, adaptive cruise con­
trol will also accelerate up to the stored
speed.
The higher the speed , the greater the distance
in yards (meters)

is recommended .
The distances prov ided are spec ified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual

A WARNING ,. -
Following other vehicles too closely in­
creases the risk of collisions and serious
personal inj ury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic. -
Always obey applicable traffic laws, use
good judgment, and select a safe follow­ ing d istance for the traff ic, road and
weather conditions.

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 98 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adaptive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own vehicle is t raveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
guard does not react if it cannot detect 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 avoid a collision . The indicator
light. in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply. The indicator
light. and indicator in the display will
warn you about the danger

If you do not react fast enough or do not react
at all to the situation, braking guard will inter­
vene by braking.
- If a col lision is imminent, the system will
first provide an
acute warning by brief ly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
co llision.
- The system can initiate maximum braking
shortly before a collision
1 ) . Full deceleration
at high speeds occurs only in vehicles with
adaptive cru ise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the brak ing force .
- The pre sense functions also engage when a
collision is imm inent

Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI

A WARNING
Lack of attention can cause collisions, oth­
er accidents and serious personal injuries .
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always responsible for braking at the cor­
rect 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 comp lete control whenever necessa­
ry . Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead .
- Braking guard works within limits and
will not respond outside the system lim­ its, for example when approaching a
