Audi braking guard
Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approach warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise control is switched off .
What can Audi 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 traveling 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
I in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­ ing much more slowly than you are or if it
brakes sharply . When th is warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply . The indicator
l ight
I and indicato r in the display will warn
you about the danger
¢ fig. 113 . You will al­
so hear an acoustic signal.

- If a coll is ion is imminent, the system wi ll
fi rst provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake within the lim its of
the system. This reduces the vehicle speed
in the event of a collision .
- At speeds under 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration

).
- If the braking guard senses that you are not
brak ing hard enough when a co llision is im­
minent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or MMI
¢ page 101, Settings in the radio/
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 dr iver 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 complete 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 examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in t raffic).

-Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent ran ces may impair the
function of the radar sensor.
- You can cance l the braking that is initiat­
ed by the system by braking yourself, by
accelerating noticeab ly or by swerving.

-Keep in mind that braking guard can
brake unexpectedly . Always secure any
ca rgo or objects that you are transport­
i ng to reduce the risk of d amage or in ­
ju ry.

Important safety instructions
Appl ies to vehicles: with knee airbags
A WARNING
Always make sure that the knee a irbag can
inflate without interference . Objects be ­
tween yourself and the airbag can increase
the risk of injury in an acc ident by inte rfer­
ing w ith the way the a irbag deploys or by
being p ushed into you as the airbag de­
ploys .
- No persons (ch ildren) or animals should
ride in the footwell in front of the pas­
senger seat. If the airbag deploys, this
can res ult in serious or fata l injuries .
- No objects of any k ind sho uld be carried
in the footwe ll area in front of the driv­
er's or passenger's seat . Bulky objects
(shopping bags, for example) can ham ­
per or prevent proper deployment of the
airbag . Small objects can be thrown
through the vehicle if the airbag deploys
and injure you o r your passengers .
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat
or any other object.
M ake sure tha t all pedals move freely witho ut
i nte rfe rence and that nothing prevents them
from retu rning to the ir origina l posi tions.
Only use floo r mats that leave the peda l area
free and can be secured wit h floor mat fasten­
e rs.
If a b rake circuit fails, increased b rake pedal
trave l is required to bring the vehicle to a full
stop.
A WARNING
Pedals that cannot move free ly can cause
l oss of veh icle control and increase the risk
of ser ious injury .
- Never p lace any objects in the drive r's
footwell . An object cou ld get into the
pedal area and inte rfe re with pedal func­
tion . In case of sudde n brak ing o r an ac­
cident, yo u wo uld not be a ble to brake or
acceler ate !
- Always ma ke s ure that no thing can fall
or move into the driver's footwel l.
Floor mats on the driver side
Always use floor mats that can be securely
attached to the floor mat fast eners and do
not interfere with the free movement of the
pedals.
.. Make s ure that the floor mats are properly
secured and canno t move and in terfere with
t he peda ls
£:=? &, .
Use on ly f loor mats that leave the pedal area
u nobst ructed and that are firmly secu red so
t h at t hey cannot slip o ut of position . You ca n
obta in suitab le floor mats from yo ur autho r­
ized Audi dea ler .
Floor mat fastene rs are insta lled in your Audi.
Floor mats used in your vehicle must be at­
tached to these fastene rs. Prope rly securing
the floor mats will prevent them from sliding
i nto posi tions that cou ld interfere with the
peda ls o r impa ir safe ope rat io n of yo ur vehicle
i n othe r ways.
A WARNING
Pedals that cannot move free ly can result
in a loss of vehicle control and inc rease the
risk of ser ious persona l injury .
- Always make sure that floor mats are properly secu red.
- Never p lace or ins tall floor mats o r othe r
floor coverings in the vehicle that cannot
be properly secured in p lace to prevent
them from slipping and interfer ing with
lill>

the pedals or the ability to control the
vehicle.
- Never place or install floor mats or other
floor coverings on top of already insta l­
led floor mats . Additional floor mats and
other coverings will reduce the size of
the pedal area and interfere with the
pedals.
- Always property reinstall and secure floor
mats that have been taken out for clean­
ing .
- Always make sure that objects cannot fall into the driver footwell wh ile the ve­
hicle is moving. Objects can become
t rapped under t he brake pedal and accel­
erator peda l causing a loss of veh icle
control.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 179
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
JjJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface. If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
A lways adjust your speed and driving style to
road, traffic and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

180 Intelligent technology
ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti-slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering" and
e lectronic interaxle differentia l lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certa in s ituations whe n you need
l ess t raction, you can switch off ASR by p ress­
i ng the bu tto n
[ru ¢ fig. 167 or ¢ fig. 168. Be
sure to sw itch ASR on ag ain when you no lon­
ger need less trac tion.
Anti -lock braking system (ABS)
ABS prevents t he wheels from locking up
when braking. The veh icle can still be st eered
even d uring ha rd b rak ing . Apply steady p res­
sure to the br ake pedal. Do no t pu mp the ped­
a l. A puls ing in t he bra ke peda l ind icates that
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assist system can decrease bra king
d ista nce. It increases braking powe r w hen the
d river p resses the brake pedal quickl y in eme r­
gency situa tions . You mus t press and ho ld the
brake peda l until the situation is over. In
ve hicles with adaptive cruise contro l", the
brake assist system is more sensit ive if the
d ista nce detected to t he vehicle a head is too
smal l.
Anti-slip regulation (ASR)
ASR reduces engi ne power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinning and
tra nsfers t he d rive powe r to the other d rive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL a utomatica lly switches
off to help keep the bra ke on the braked whee l
from overheating. EDL will switch on aga in au­
tomatically when conditions have returned to
normal.
Dynamic steering*
On vehicles wi th dynam ic s teering *, ESC he lps
sta bilize the steer ing in crit ica l sit uat ions.
Electronic interaxle differential lock*/
selective wheel torque control*
T he ele ctroni c in te raxle di fferentia l lock ( fron t
whee l drive) o r th e se lective whee l torque
control (all -whee l drive) operates when driv­
ing t hro ugh cu rves. The front wheel on the in­
s ide of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
Th is mi nimizes sliding in the front wheels and
allows for more precise d rivi ng through
cu rves . The a ppl icable syste m may not acti­
vate when dr iv ing in wet o r snowy cond itions.
_&. WARNING
- E SC, A BS, ASR, ED L d ynam ic steering *

This is especia lly important on slippery
or wet r oads. If the systems beg in acting
to stabilize your veh icle, yo u should im­
mediately change you r speed to match
the road and t raff ic conditions. Do not
let the increased safety prov ided by
t hese systems temp t you to ta ke r is ks.
Doing so will increase the risk of a lo ss of
veh icle cont ro l, col lision an d ser io us per­

driving too fast, es pec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
