brake light AUDI A5 COUPE 2018 Owner's Manual

Ass is tan ce sys tems
operation. You are always responsible for
your speed and the distance between your
vehicle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road condit ions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because th is increases the
risk of an accide nt.
- Switch the cru ise control off temporar ily
when driving in turn ing lanes, h ighway exits
o r in construction zones.
- Please note that u nconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­
ca use p ressing the acce le rato r pedal
over­
rides the cruise contro l system.
- If a brake system ma lf u nction such as over­
heating occu rs when the c ruise control sys­
tem is switched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain
act ive as long as the
tij;jl)~i# (USA models) /
ii (Canada models) indicator light is on.
(D Note
Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. Th is makes use of the eng ine
braking effect and relieves the brakes.
(D Tips
- Applies to: vehicles with manual transmis­
sion: The set speed can on ly be reached if
the engaged gear permits it so that the en­
gine is not over-rewed and will run smooth­ ly. Therefore, sh ift into the higher or lower
gear in a timely manner .
- The brake lights turn on when the brakes are applied automatically.

Predictive control
(efficiency assist)
Description
Applies to: vehicles with Audi adaptive cruise control and pre·
dict ive efficiency assist
Fig. 122 Instrument cluster: predictive control
General information
The predictive control 1l uses the map informa·
tion from the navigation system in order to react
proactively when driving. Information from the
camera -based traffic sign recognition* is also ap·
plied to recognize traffic signs
r::!> page 109.
When coming up to areas with speed limits or
changes in the course of the road (such as curves,
inte rsections or traffic circles), the system brakes
automatically and then accelerates back up to
the set speed.
When adaptive cruise cont rol is switched off, the
system only provides notificat ions without con­
trolled intervent ions
r::!> page 112 .
The driver can override the predictive control at
any time by pressing the accelerator or brake
pedal. If the system changes the vehicle speed to
adapt to speed limits, you can ch ange the speed
using the lever
<:!> page 117 , fig . 117 .
Always switch off the predictive control in
the following situations:
- When increased attention is needed from the
driver .
- In poor we ather condit ions such as snow or
heavy rain .
- When driving on roads in poor condition.
l) This is no t a vail able in som e coun trie s.

Audi pre sense
Introduction
App lies to: vehicles with Audi pre sense
Within the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the vehicle pas­
sengers and other road users.
- Due to the interlinking of various vehicle sys­
tems, critical driving situations can be detected by
pre sense basic and measures for preventa ­
t ive occupant protection are can be initiated .
- The
pre sense front system uses the data from
the adaptive cruise control* radar sensors and
the camera to calculate the probability of a col­
li sion. Within the limits of
the system, an im­
pending collision with vehicles can be detected
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary. If needed, it can initiat e a partial or full
deceleration to reduce the collision speed or to
avoid the collision under certain circumstances .
I n conjunction with pre sense basic/rear, the
front safety belts are also revers ibly tensioned
when needed . The pre sense front is also active
when adapt ive cruise control* is switched off .
-Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra­
dar sensors and calcu lates withi n the limits of
the system the probability of a rear end coll i­
sion with the vehicle beh ind you. Pre sense rear
is also active when side assist* is switched
off.
- Within the limits of the system, pre sense city
uses the camera data and can detect an im­
pending collision with vehicles and pedestrians.
In this case, the system warns the dr iver visual­
ly, acoustically and with a jerk on the brakes if
necessary. If needed, it can initiate a full decel­
eration to reduce the collision speed or to avoid
Assistance systems
the collision under certain circumstances. In
conjunction with pre sense basic/rear, the front
safety belts are a lso reversibly tens ioned when
needed .
A WARNING
Read the genera l information in c:>&. in Gen­
eral information on page 114,
c:> &. in Gener­
al information on page 135.
(D Tips
- Certain pre sense functions switch off when driving in reverse.
- The pre sense functions may not be availa­ ble if there is a malfunction in the ESC sys­
tem or the airbag control module.
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated .
- Switch the pre sense
off when you a re not
using public streets or when loading the ve­
hicle onto a vehicle carrier, tra in, sh ip or
other type of transportat ion. This can pre­
vent an undesired inte rvention from
the pre
sense system.
Audi pre sense basic
Description
Applies to : vehicles with Audi pre sense basic
The pre sense basic functions are activated at a
speed of approx imately 20 mph (30 km/h) or
higher .
The following functions can be triggered under certain conditions within the limits of the sys­
tem:

factory, the pre sense rear functions switch off
when the electrical connector at the socket is
plugged in. There is no guarantee the functions
will switch off when using a retrofitted trailer
hitch.

Intelligent Technology Electronic stabilization
control (ESC)
Description
Ele ctronic stabilization control (ESC) supports
driver safety . It reduces the risk of slipping and
improves d riving stability. ESC detects critica l sit ­
uations such as when the vehicle is oversteering
and understeering or the wheels are spinn ing.
T he vehicle is stabilized by applying the brakes or
reducing eng ine torq ue. When the ESC engages,
the
J;,j ind icator light blinks in the instrument
cluste r.
T he follow ing systems are integrated in the ESC:
Ant i-loc k bra king s ystem (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
b rake pedal indicates that the system is act ing to
stabilize the vehicle .
Br ake a ssist s ystem
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
unti l the dangerous sit uat io n is ove r. In veh icles
with adaptive cr uise contro l*, the bra ke assist
system is more sensitive if t he d istance detec ted
to the veh icle dr iv ing ahead is too small.
Anti-Slip Regulation (ASR )
ASR red uces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions . This makes it easie r to sta rt, acceler­
ate and dr ive up hill s.
Electronic differenti al lock (EDL )
EDL applies the brakes to a wheel that starts
spi nning and t ransfers t he drive powe r to the
;;§ other driving wheels. This f unct ion is not availa-....
~ b lea t higher speeds.

3 Intellig ent Technology
In extreme cases , ED L automat ica lly switches off
to keep the brake o n the braked wheel from over­
heating. The veh icle is still working correct ly. ED L
will switch on again automatically when condi­
tions have returned to normal.
Ste ering recommendation
The ESC he lps to stabilize the vehicle by changing
the steering torque.
In veh icles wi th dynamic steer ing*, ESC also
helps to stab ilize the steer ing in crit ica l sit ua ­
tions.
Selective wheel torque control
Se lective w heel to rque con trol is used w hen d riv­
i ng on curves. Bra king is targeted towa rd t he
whee ls on the inside of the cu rve as needed. This
allows mo re precise driving in curves .
Automatic post -collision braking system
The "automat ic post-collision braking system "
can help to reduce the risk of sliding and of addi­
tiona l co llisions after an acciden t. If the a irbag
contro l
module detects a co llision, the veh icle is
braked by the ESC.
T he veh icle does not bra ke automatically if:
- the dr iver presses the acce lerator pedal, or
- the ESC, the brake system or the veh icle elect ri-
cal system are not functioning.
A WARNING
=
- The ESC and its integrated systems cannot
overcome the lim its imposed by natural
phys ica l laws. This is especially important
on slippery or wet roads. If the systems be­
gin acting to s tabilize yo ur vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please note the ris k of a collis ion increases
when dr iv ing fast, especially through curves
and on slippery or wet roads, and when dr iv-
ing too close to objects ahead . The ESC and
