2013 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
[O] 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 213, Engine compartment . Oth­
erwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied .
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 veh icles: w it h m ult itro nic/S tro nic/t iptro 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 205. 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.
, In curves
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 ­
a ry object
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.

The adaptive c ruise control is avai lab le from
the 2nd gear through the 6th gea r in the cus­
tomary RPM.
When the adapt ive cruise control is turned on,
you must p ress the clutch to shift gears (as
usual) . When sh ifting normally or when press­
ing the cl utch, the adap tive c ruise control re­
mains turned on.
Afte r you have engaged the gear, you do
not

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
