~ To increase or reduce the distance by incre
ments, tap the switch again to the left or
right. The distance between the two veh icles
will change in the instrument cluster dis
play.
When approaching a moving vehicle up ahead,
the adaptive cru ise cont rol system brakes to
matc h that object's speed and then maintains
the stored distance. If the vehicle ahead ac
celerates, adaptive cruise control will a lso ac
celerate up to the stored speed.
The higher the speed, the greater the distance
in yards (meters)¢ ,&.. T he
Distance 3 setting
is recommended .
The distances p rov ided are spec ified values.
Depending on the driving situation and the
how the vehicle ahead is dr iving, the actual
distance may be more or less than these tar
get distances .

A WARNING
Following other veh icles too closely in
creases the risk of collis ions and ser ious
personal injury.
- Sett ing short distances to the traffic
ahead reduces the time and d istance
availab le to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic.
-
-Always obey applicab le traffic laws, use
good judgment, and se lect a safe follow
ing distance for the traffic, road and
weather conditions .

whe n adapt ive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a veh icle ahead brakes s ud
denly or if your own vehicle is t raveling at a
high speed and approac hing a ve hicle up
ahead that is movi ng mo re sl ow ly. Audi brak
ing guard does not react if it canno t detect
the si tua tion.
The system advis es yo u of various s ituations:
- The
distance wa rning is given if yo u are too
close to the vehicle ahead for a long time. If
the vehicle ahead bra kes sharply , yo u will
not be ab le to avoid a collision . The ind icator
light

- The
approach warning is given when a de

- If a co llision is imminent, the system will
first provide an
acute warning by bri efly and
sharp ly app ly ing the brakes .
- If you do not react to the ac ute warning ,
braking guard can brake within the limits of
the system. This reduces the veh icle speed
in the event of a collis ion.
- At speeds under 20 mph (30 km/h), the sys
tem can in it iate a complete deceleration
s hortly before a collision .

- If the Audi braking guard senses that you
are not braking hard enough when a colli
sion is imminent, it can increase the braking
force .
Which functions can be contr oll ed ?
You can sw itch Audi braking g uard and the
distance/approach warning on or off in the ra
d io or MMI Qpage 102, Set tings in the ra
dio/MM!.
A WARNING
Lack of attention can cause col lisions, oth
er accidents and serious persona l injuries.
The Audi b raking guard is an assist system
and cannot prevent a collis ion by itself.
The driver must always intervene. The dr iv
er is always responsible for braking at the
correct time.
- Always pay close attention to traffic,
even when the Audi braking guard is
switched on. Be ready to intervene and
be ready to take comp lete control when
ever necessary. Always keep the safe and
legal distance between your vehicle and
vehicles up ahead .
- Audi braking guard works within limits
and w ill not respond outs ide the system
limits, for examp le when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar s ensor
for the A udi braking guard works only
within defined detect ion and range limits
l ) Th is is not available in some c oun tries .
that may prevent the proper detection of
other veh icles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving veh icles up ahead may not
be prompt ly detected or may not be de
tected at all .
- Reflective surfaces including crash barri
ers or tunne l entrances may impair the
function of the radar sensor .
(D Tips
- You can cancel the braking that is in it iat
ed by the system by braking yourse lf, by
accelerating not iceably or by swerving .

Audi drive select Driving settings
Introduction
App lies to vehicles: w it h drive se lect
Aud i drive select provides the possibility to ex
perience different types of veh icle sett ings in
one veh icle. For instance, using the three
C o mfort , Au to and Dyna mic modes, the driv
er can switch from a sporty to a comfortab le
driving mode with the press of a button.
Addit ionally, in vehicles with MM I*, the vehi
cle setup for
Indi vidual * mode can be cus
tomized by you. This makes it possib le to
combine settings such as a sporty engine tun
ing with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri
ous personal injury.
Description
Ap plies to vehicles: w it h drive se lect
The vehicle setup in each mode depends on
the vehicle's features. However, the engine,
automatic t ransmission* and steering are al
ways involved.
.
Engine and automatic transmi ssio n*
Depending on the mode, the engine and the
automatic transmission respond quicker or in
a more ba lanced manner to acce lerator pedal
movements. In the sporty dynamic mode, the
automatic t ransmission shifts at h igher R PMs .
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect steer ing that
moves eas ily, like the stee ring in comfort
mode, is best su ited to long dr ives on a high
way. In contrast, dynam ic mode prov ides
sporty, di rect steering .
The follow ing applies to vehicles with dynam ic
steer ing*: the stee ring ratio changes based on
ve hicle speed in order to maintain optimum
Aud i dri ve sel ect 109
steering effort for the drive r at all times. This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steer ing
is more d irect in order to keep the steering ef
fort as minimal as poss ible when the driver is
maneuveri ng the vehicle . At low and average
speeds, dynamic steering addit iona lly pro
vides more responsive stee ring pe rformance.
Adapt ive dampers*
The adaptive dampers* use sensors to record
i nformation regarding steering movements,
braking and acceleration ope rations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the d riving situation v irtually i n rea l time.
Audi drive select also makes it possible to sat isfy the desire for sporty s uspension (Dynam
ic) and comfortable suspension (Comfort)
without giv ing up ba lanced tuning (Auto).
Sport diff ere ntial *
As a component of the all whee l dr ive system
(quattro ®)
q page 190, the sport differential*
distributes the driving power to the rear ax le
depending on the situation . The distribution
of power var ies depending on the mode se
lected. The goal is a high level of agility and
ability to accelerate on curves . The ve hicle is
very respons ive to steering .
Adaptive crui se control *
The behav ior when accelerating can be adjust
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise control
also responds to the driv ing behavior of the
vehicle ahead in a mo re conservative or spo rty
manner .
Engine sound*
The sound of the eng ine is adapted to the se
lected mode and ranges from subtle to sporty.
0) Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto
and D ynamic modes.

Parking system
Applies to vehicles: with pa rking system
Different park assist systems may be used for
parking or maneuvering, depending on the
vehicle's features.
Parking system (rear)*:
For the parking system (rear), the acoustic
park assist system is installed in the rear of
the vehicle
¢ page 112.
The rear parking assist system uses ultrason ic
sensors to determine the distance of the vehi
cle from a detected obstacle. There are a total
of four sensors located on the rear bumper
(two in the middle and two on the sides).
Parking system (rear, with rear view
camera)*:
For the parking system (rear, with rear view
camera),
the rear acoustic park assist system
is integrated in the rear of the vehicle and the
rear view camera is integrated in the rear lid
¢page 115.
The parking system (rear, with rear view cam
era)
uses ultrasonic sensors to determine the
distance of the vehicle from a detected obsta
cle . There are a total of four sensors located
on the rear bumper (two in the middle and
two on the sides).
Parking system (rear)
Rear acoustic park assist
App lies to vehicles: with parking system (rear)
The rear acoustic park assist warns you of ob
stacles or objects behind your car.
Description
The rear acoustic parking ass ist system deter
mines the distance of the vehicle from an ob
stacle using ultrasonic sensors. There are 4
sensors in the rear bumper.
The range at which the senso rs start to meas
ure is
about :
To the side 2 ft (0.60 m)
Center rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is activated automati
ca lly when
reverse gear is engaged. A brief
tone confirms that the system is activated.
Warning tones
Distance warning is given by warn ing tones
which are generated by the rear signal genera
tor. The volume and the pitch of the warning
tones can be adjusted in the MMI*
¢page 113.
Reversing
Distance warning when reversing starts when
an obstacle is detected in the range of the
parking assist system . As the distance de
creases, the time interval between the audible
tones becomes shorter.
When the distance is less than 1ft (0.30 m),
the tone becomes continuous. At this point
you should stop backing up .
Please note that low objects already signalled
by a warning can disappear from the system's
detection range and will not continue to be
signalled .
If the distance to an obstacle remains the
same, the volume of the distance warning is
gradua lly reduced after about 4 seconds (this
does not apply in the continous tone range).
Approaching another obstacle will resu lt in
the distance warning sounding at the normal
volume again.
Malfunctions in the system
If a warning tone is audible for about five sec
onds when you turn on the ignition , there is a
malfunction in the system. Have the problem
corrected by your authorized Audi dealer.
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park assist
system can function properly.
