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 cruise
control works like a regu lar cruise contro l sys­
tem. The stored speed is ma intained . When ap­
proaching a moving vehicle detected up ahead,
the adaptive cruise control 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 traff ic, 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
c;, page 83 . Adaptive cru ise 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"
c;, page 81, Switching on and off.
When driving, you can stop cruise control
c;, page 83 or change the speed ¢ page 82 at
any time. You can also set the distance to the object ahead
and set the adapt ive cruise control driv ing pro­
gram

speeds below 20 mph (30 km/h), will auto­
matically accelerate the vehicle to 20 mph (30 km/h), which is the minimum speed
that can be set.
@ Tips
-If you switch the ignition or the adaptive
cruise control off, the set speed is erased
from the system memory.
- The electronic stabilization control (ESC)
and the anti-slip-regulation (ASR) are auto·
matically turned on when the adaptive

a:: CJ ' Audi braking guard
Description
Applies to: vehicles with Audi adaptive cruise contro l
Fig. 96 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 suddenly
or if your own veh icle is 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 si tuat ion.
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 . T he indicator light .
in the d isplay 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 g iven, it may only be pos­
s ib le to avoid a collision by swerving or braking
sharp ly. The indicator light. and indicator in
the display will warn yo u about the danger
¢
fig. 96. You will also hear an acoustic signa l.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
by braking.
N "' ll This is not available in some countries . ......
-If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
apply ing the brakes .
- If you do not react to the acute warning, brak­
ing guard can brake with increas ing force with­
in the limits of the system. This reduces the ve­
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a collision
1 ). Full dece leration at
high speeds occurs only in vehicles with adap­
tive cruise control and side assist (pre sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
- The pre sense functions also engage when a
collision is imm inent ¢
page 177.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 86, Settings in the Infotainment sys­
tem .
A WARNING
--
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . Th e driver must
always intervene. The driver is always respon­
sib le for b raking at the co rrect 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.
- Brak ing guard works with in limits and will
not respond outside the system limits, for
example when approach ing a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
f ic).
- Always remember that the radar sensor for
the braking guard works only within defined
~
85

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
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.
@ Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving .
- Braking guard error messages¢
page 86.
- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

Automatic transmission
-Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptron ic".
- 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
[i'J illuminates
and a driver message appears
¢ page 105
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
¢ page 203. Otherwise, any increase in en ­
gine speed may set the vehicle in motion,
even with the parking brake applied .
@ 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
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.
(D 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 declines .
Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
that 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. If 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.
On vehicles with the cruise control system*
Q page 77, hill descent control is also activated
when the speed is set.
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.

Audi pre sense Preventative passenger
protection
Applies to: ve hicles with Audi pre sense
Pre sense can initiate steps to protect vehicle oc­
cupants in certain dangerous situations. The
functions described are available depending on
veh icle equ ipment:
Pre sense basic*
The following functions can be triggered in cer­
tain driving situations:
- Tightening of the safety belts (for examp le,
during emergency braking): the front safety
belts have reversib le belt pretensioners. If a
collision does not occur, the safety belts loosen
slightly and are ready to trigger aga in.
- Closing the w indows and the sunroof* (for ex­
ample, when over- or understeering) : the win­
dows and the sunroof* close until there is only
a small gap open .
Audi pre sense basic functions can be triggered at
speeds above 20 mph (30 km/h). Drive select: the deployment time is adapted in
Dynamic mode .
Pre sense front (vehicles with adaptive cruise
control*)
Pre sense front contains the functions of pre
sense basic . In addition, the likelihood of a rear ­
end collision with the vehicle ahead is also calcu­
lated, within the limi ts of the system. If the risk
of a collision is detected, the following functions
can trigger:
- Braking guard
c> page 85
- Tensioning of the safety belts
- Closing the windows and the sunroof*
Pre sense rear (vehicles with side assist*)
Pre sense rear contains the functions of pre sense
bas ic. In addit ion, the lik el ihood of a rear-end
coll is ion from the vehicle behind is also calculat­
ed, within the limits of the system. If the risk of a
collision is detected, the following functions can
trigger:
Audi pre sense
-Tensioning of the safety belts
- Closing the windows and the sunroof*
Pre sense plus*
Pre sense plus contains the functions of pre
sense front and pre sense rear .
Error message
Aud i pre sense: Unavailable
Preventative passenger protection is not availa­
ble. Drive to your authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the malfunction corrected.
A WARNING
=
Pre sense cannot overcome natural phys ica l
laws . It is a system designed to assist and it
cannot prevent a collision . Do not let the in­
creased safety provided tempt you into taking
risks. This could increase your risk of a colli­
sion.
- The system can dep loy incorrectly .
- Please note that the sensors do not always
detect all objects . This increases the risk of
a collision.
- Pre sense does not react to people or ani­
mals or objects that are crossing the vehi­
cle's path or are difficu lt to detect
.:>page 79.
-Reflective objects such as guard ra ils or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collision risk.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
un derbody. Pre sense can be impaired by this.
Have an authorized Audi dealer or authorized
Audi Service Facility check their function .
(D Tips
-Certain pre sense front functions switch off
when sport mode is switched off or when
driving in reverse. ..,.
