2014 AUDI S4 Owners Manual

-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 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 auto­
matically when it becomes too hot from
the overload. An indicator lamp
mJ illu­
minates and a driver message appears
¢ page 9 7 when 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
¢ page 214. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied .
0 Note
-S tronic- and tiptronic transmission:
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.
- S tronic- and tiptronic transmission: Al­
lowing 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 .
(D 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
App lies to vehicles : wi th mult itronic/ S tro nic/tiptro nic
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. It 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.
On vehicles with the cruise control system*
¢ page 89 , hill descent control is also activat­
ed when the speed is set.
.&_ 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 adaptive cruise control and braking guard 99
Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system . If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac­
celerate your vehicle . This he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c::;, page 1 OS.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them properly at all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 110 Front of the vehicle: Position of radar sensor
The area that contains the radar sensor
c::;, fig. 110 must never be covered by stickers
or other objects or obstructed with dirt, in­
sects, snow or ice that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c::;, page 204. The same applies for any modifi­
cations made in the front area . The
function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
.:!>page 101 , fig. 113.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane.
- Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
- When driving through curves
c::;, page 100.
-Stationary objects c::;, page 100.
A WARNING
-Always pay attention to traffic when adap-
tive cruise control is switched on and brak­ ing guard is active. As the dr iver, you are
still respons ible for start ing and for main­
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a collision. The driver is always responsible
for braking at the correct time.
- Improper use of adaptive cruise con trol
can cause collisions, other accidents and
serious personal injury .
- Never let the comfort and convenience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic conditions and the
need to remain in fullcontrolofyourve­
hicle at all times,
- Always remember that the adaptive
cru ise contro l and braking guard have
limits -they will not slow the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
moving, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obstacles that are not moving can
trigger a collision warning and if .,.

100 Audi adaptive cruise control and braking guard
confirmed by the video camera, an acute
collision warning.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construc tion
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations.
- Th e adaptive cruise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cr uise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects .
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
ano ther vehicle too closely . Always re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
{[) Note
The sensor can be d isp laced by impacts or
damage to the bumper, whee l housing and
underbody . That could affect the adaptive cruise control system and b
raking guard.
Have your authorized Audi dea ler or au­
thorized Audi Service Facility check their
function.

Applies to vehicles: wit h Aud i adapt ive cr uise contro l
Fig . 111 Examp le: driv ing into a curve
When driving into a curve <=> fig. 111 and out
of a curve, the adaptive cruise control may re­ act to a vehicle in the next lane and app ly the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
Stationary objects
Applies to vehicles: with Aud i adaptive crui se contro l
Fig. 112 Examp le: object chang ing lanes a nd station ­

The adaptive cru ise control system only reacts
to objects that are moving or that the system
has a lready detected as moving. For example,
if a vehi cle@ , which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

Description
App lies to vehicles: with Audi adaptive cruise control
Fig . 11 3 Detect ion range
What c an Audi adapt ive crui se cont rol d o?
The adaptive cruise control works in conjunc ­
tion with a radar sensor installed in the front
of the vehicle
¢page 99, fig. 110, which is
subject to desig nated system limits
<=:> page 101 . Stationary objects are disregard­
ed . On open
roads with no traffic, adaptive cr uise
control works like a regular cruise contro l sys­
tem. The stored speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au­
tomat ica lly slows down to match that vehi ­
cle's speed and then maintains the distance
that the dr iver previously stored . As soon as
the sys tem does not detec t a vehicle up
ahead, adaptive cruise cont ro l ac celerates
back up to the stored speed .
Which functions can be controlled?
When you switch adapt ive cruise control on,
you can set the cu rrent speed as the "contro l
speed "
¢ page 102, Switching on and off.
When dr iving, you can stop cru ise contro l
¢page 103 or change the speed ¢page 103
at any time.
You can also set the distance to t he object
ahead and set the adapt ive cru ise control driv ­
ing program
