Audi adaptive cruise control and braking guard 113
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 124 Instrument cluste r: approac h 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 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
gua rd 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 wi ll
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 this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light
I and indicator in the display will warn
you about the danger
c:> fig. 124. You will al
so hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter-
ll Th is is not ava ilable in som e coun tri es.
vene by braking and the message Braking
guard: Activated
will appear.
- If a coll ision is imminent , the sys tem wi ll
first 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 limits 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 complete deceleration shortly before a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision 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/
MMI* i::!> page 114, 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 driver is
always respons ible for braking at the cor
r ect time .
- Always pay close attention 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 examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traff ic).

Automatic
transmission
tiptronic
Introduction
The automatic transmission is controlled elec
tronically. The transmission upshifts or down
shifts automatically depending on which drive
program is selected. The power is transferred
by a torque converter .
When a
mode rate d riv in g s ty le is used, the
transmission selects the most econom ica l
driving mode. It w ill then change up early and
delay the downshifts to g ive better fuel econ
omy.
T he transmission switches to a sporty mode
after a k ick-down or when the driver uses a
spo rty driving sty le characterized by quick ac
celerator pedal movements, heavy accelera
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can a lso select the gears
manually ( tiptronic mode ) c:> page 12 7.

8_ WARNING
-Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into
R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re
duces braking performance, increases
braking distance or causes complete fail
ure of the brake system .
- To preven t the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake.
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu
minates and a driver message appears
Q page 128when the clutch is overload
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
Q page 226, Engine compartment . 0th-erwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied.
(D Note
- When stopping on an incline , do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis
sion to overheat and can damage it. Acti
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en
gine is stopped and the selector lever is
in N will damage the transmission be
cause it is not lubricated under those cir
cumstances.
@ Tips
For safety reasons, the parking brake is re
leased automatically only when the driv
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these
lector lever is in D /S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de
scent control tries to maintain the speed ach
ieved at the time of braking, within physical
and technical limitations. If may still be nec
essary to adjust the speed with the brakes .
Hill descent control switches off once the de
cline levels out or you press the accelerator
pedal.
When the speed is set in the cruise control
system
q page 95, hill descent control is also
activated.
A WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
Page 129 of 316
conditions. Always be ready to apply the
brakes.

The transmission only allows manual shifting
when the eng ine speed is with in the permit
ted range .
@ Tips
-When you shift into the next lower gear,
the transmission will downshift only
when there is no possibility of over-rev
ving the engine.
- When the kick-down comes on, the
transmission will shift down to a lower
gear, depending on vehicle and engine
speeds.
- Tiptron ic is inoperative when the trans
mission is in the fail-safe mode.
- Hybrid drive*: electric driving is not pos
sible in tiptronic mode.
Kick-down
Kick-down enables maximum acceleration .
When you depress the accelerator pedal be
yond the resistance point, the automatic
transmission downsh ifts into a lower gear, de
pending on vehicle speed and engine speed .
The upshift into the next higher gear takes
place once the max imum specified engine
speed is reached .
_& WARNING
Please note that the drive wheels can spin
if kick-down is used on a smooth slippery
road -there is a risk of skidding .

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
The Electronic Stabilization Control (ESC) rein
forces driver safety. It reduces the risk of slip
ping and improves driving stability. ESC de
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy
namic steering*, hill descent assist and selec
tive wheel torque control.
Anti-lock braking system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres
sure to the brake pedal. Do not pump the ped
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au
tomatically when conditions have returned to
normal.

Brake system
Operating conditions and driving habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat
ing conditions and dr iv ing habits ¢&. . On
vehicles that are e ither driven mostly in stop
and -go city traffic or are driven hard, the
brake pads should be checked by your author
ized Audi dealer more often than specified in
the
Warranty & Maintenance booklet . Failure to have you
r brake pads inspected can result
in reduced brake performance.
On steep slopes , you should use the braking
effect of the engine . This way, you prevent un
necessary wear on the b rake system . If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter
vals.
Noises may occur when braking depending on
the speed, braking force and outside condi
t ions such as temperature and humidity .
Moisture or road salt
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few careful brake applications should dry off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
the windshie ld wipers on, the brake pads will
briefly touch the brake discs in regu lar inter
vals so as to improve reaction time when brak
ing on wet surfaces . You, the driver, will not
notice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and the brakes are not used . Here too,
you should clean off accumulated salt coating from brake discs and pads w ith a few careful
applications of the brake ¢.& .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corros ion to form on
the discs if the car is not driven regularly or
o n Ly for short trips with little use of the
brakes.
If the brakes are not used frequently, or if cor
r os ion has formed on the d iscs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed¢ ,&. .,..
Page 203 of 316
Fa u lts in th e brake sy stem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circuits may have failed~.&. .
Low brak e flu id level
Malfunct ions can occur in the brake system if
the brake fl uid leve l is too low . T he b rake fluid
l eve l is monito red electronically .
Brake booster
The brake booster increases the pressure that
you generate w ith the brake pedal.
It only op
e rates while the eng ine is running or with the
i gnit ion sw itched on (hybr id dr ive*) ~.&, .
Brake lining wear statu s
Brake lining wear may be checked by visual in
spection of the condition of the brake pads
through the openings in the whee l. If neces
sa ry, the wheel may be removed for this in
spection
~ page 2 74, Changing a wheel.
.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often . This could cause the
brakes to get hot and dimin ish b raking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the b rakes to
overheat, premat ure wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa
ter , driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
Int ellig ent technolog y 201
for a test. Brakes will dry and ice coat
ings w ill be cleaned off after a few care
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
f low to the front brakes is not obst ruct
ed. Otherw ise the brake system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impair
the braking capability resulting in an in
creased stopping distance . Avoid driving
the vehicle and have it towed to the near
est a uthori zed Audi dea ler or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
