2013 AUDI S4 SEDAN sensor

-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain situations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly. The display may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface .
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system .
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
(D Tips
- If the window glass in the driver's door
or front passenger's door has been tint­
ed, the display in the exterior mirror may be misinterpreted.

Audi drive select Driving settings
Introduction
App lies to vehicles: w it h drive se lect
Audi drive select provides the possibility to ex­
perience different types of veh icle sett ings in
one vehicle. For instance, using the three
Comfort, Auto and Dynamic 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
Individual* 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 transmission*
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 transmission shifts at higher R PMs.
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect steer ing that
moves easily, like the stee ring in comfort
mode, is best su ited to long dr ives on a high­
way. In contrast, dynamic 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 hicl e speed in order to maintain optimum
Audi drive select 111
steering effort for the driver 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 direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuveri ng the vehicle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive steering pe rformance.
Adaptive dampers*
The adaptive dampers* use sensors to record
i nformation regarding steering movements,
braking and acceleration operations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the driving situation virtually 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 balanced tuning (Auto).
Sport differential*
As a component of the all whee l dr ive system
(quattro ®)
q page 189, the sport differential*
distributes the driving power to the rear axle
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 cruise control*
The behavior 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 driving behavior of the
vehicle ahead in a more conservative or sporty
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 Dynamic modes.

114 Park assist
Park assist
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 114.
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 117.
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
Applies 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 115.
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.

_& WARNING
-Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals,
since they are not always detected by the
sensors.
- The acoustic park ing system is not a sub­
st itute for the driver 's own caution and
alertness. Ultimate responsibi lity always
remains with the driver during parking
and simi lar maneuvers . Always watch
where you are driving.
- You should always adjust the volume and
frequency of the warning tones so that
yo u can easily hear the acoustic distance
warning even if the radio is p laying, the
air-cond itioner blower is on High or there
is a high level of outside noise .
- Check the settings whenever anyone
else has driven the vehicle before you.
(D Note
-Remember that low obstacles for which
a warn ing has already been issued may
"dive" below the system's sensing zone if
the vehicle is being backed up closer. In
this case, the warning sound shutting off
does
not in dicate that you have cleared
the obstacle . Instead, impact is immi­
nent.
- Objects such as trailer hitches, chains,
narrow posts or fences covered by a th in
l ayer of paint may not always be detect­
ed by the system. They can still damage
your vehicle without warning .
@ Tips
Keep the sensors in the rear bumper clean
and free of snow and ice so that the acous­
tic parking assist system can function
properly.

~ Sensors in the bumper
Sensors are loca ted in the rear bumpers. If
these detect an obstacle, audible and visual
s ignals warn you. The range at which the sen­
sors begin to measure is approx imately:
To the side 2
ft (0.60 m)
Center rear 5.2 ft (1.60 m)
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),
t h e tone becomes continuous. At thi s point
you should stop backing up.
If the distance to an obstacle stays the same,
the volume of the distance signal chime is
gradually reduced after about 4 seconds (does
not affect the contin uous signa l tone) . Ap­
proaching another obstacle will cause the d is­
tance signal to sound agai n at the normal vol­
ume.
Rear view camera coverage area
T he MMI display shows the area covered by
the rear view camera
c:> fig. 116 (D . Objects
that are not in the area covered @are not
shown on the MMI display .
We recommend that you practice parking with
the rear view camera in a traffic-free location
or parking lot to become familiar with the sys­
tem, the orientation lines, and the ir function.
When doing this, there should be good light
and weathe r cond itions.
In the MMI display, objects or vehicles appear
closer or further away if:
- you are driving in reverse gear from a leve l
surface onto an incline, or a downward
slope,
- you are driving in reverse gear toward pro­
trud ing ob jects,
- the vehicle is car ry ing too much load in the
rear.
