When approaching a moving vehicle up ahead,
the adapt ive cruise control system b rakes to
match that object's speed and then maintains
the stored distance.
If the vehicle ahead acceler
ates, adaptive cruise control will also accelerate
up to the stored speed .
The higher the speed, the greater the distance in
yards (meters)

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise contro l
Fig. 126 In strument cluste r: appro ach warning
Braking guard uses a radar sensor. It also func
tions within the limits of the system when adap
tive cruise control is switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a veh icle ahead brakes suddenly
or if your own vehicle i s traveling at a high speed
and approaching a vehicle up ahead that is mov
ing more slowly . Braking guard does not react if
it cannot detect the situat ion.
The system advises you of variou s 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 indic ator light .
in the display comes on.
- The
approach warning is given 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 given, it may only be pos
s ib le to avo id a collision by swerving or braking
sharply. The indicator light . and indicator in
the display will warn you about the danger
¢fig. 126. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
a ll to the situation, braking guard will intervene
by braking and the message
Braking guard: Acti
vated
will appear.
l) Thi s is no t a vail able in som e coun trie s.
112
- If a collision is imminent, the system will first
provid e an
acute warning by briefly and sharply
app ly ing the b rakes.
- If you do not react to the acute warning, brak
ing guard can brake within the limits of the sys
tem . This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a comp lete deceleration shortly be
fore a collision ll.
- If the braking gua rd senses that you are not
braking hard enough when a collision is immi
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio/MM
I*
¢ page 113 , Settings in the radio/MM!* .
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious 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 respon
sible for braking at the correct time .
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al
ways keep the safe and legal distance be
tween your vehicle and vehicles up ahead .
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approach ing 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 guard works only within defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
-
,....,
N
co
er::
co
,....,
promptly detected or may not be detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
(D Tips
- You can cancel the braking that is initiated
by the system by braking yourse lf, by accel
erating noticeably or by swerving.
- Braking guard error messages
¢page 113 .
-Keep in mind that braking guard can brake
unexpected ly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

Introduction
The automat ic transmission is controlled e lec
tron ically . The transmission upshifts or down
shifts automatically depending on wh ich dr ive
p rogram is selected. The powe r is transferred by
a torque converter .
When a
moderate driving style is used, the
transmission se lects the most economical d riving
mode .
It will then change up early and de lay the
downshifts to give better fuel economy .
The transm ission switches to a spo rty mode afte r
a kick-down or when the drive r uses a
sport y
d riv ing sty le
charac ter ized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the dr iver can a lso select the gears
manually ( tiptronic mod e) ¢ page 126.

running while in gear. If you must leave
your vehicle when the engine is running, ac tivate the parking brake and move the selec
tor lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre
vent the vehicle from "creeping", you must keep your foot on the brake when the en
gine is running and the selector lever is in D/
5 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, reduce
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 brak
ing distance or causes complete failure of
the brake system .
- To prevent 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 automati
cally when it becomes too hot from the
overload . An indicator lamp
[ijJ illuminates
and a driver message appears
c> page 126
when the clutch is overloaded .
- If the engine must remain running, never
have any driving position engaged when
checking under the hood.
Make sure these
lector lever has securely engaged and is
locked in P with the parking brake set
c> page 220. Otherwise, any increase in en
gine 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 ac
celerator pedal while a driving gear is se-
Automatic transmission
lected. This can cause the transmission to
overheat and can damage it. Activate the
parking brake or press the brake pedal to
prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances.
(!) Tips
For safety reasons, the parking brake is re
leased automatically only when the driver's
safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the driver
when driving down decline s.
Hill descent control is activated when the selec
to r lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
tha t is suitable for the incline. Hill descent con
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitations. It may still be necessary to adjust the
speed with the brakes .
Hill descent control switches off once the decline
levels out or you press the accelerator pedal.
When the speed is set in the cruise control sys
tem
c> page 95 , hill descen t control is also ac ti
vated .
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions . Always
be ready to apply the brakes.
