2015 AUDI S3 SEDAN stop start

Assist
Assist Electronic speed limiter*
Applies to veh icles: with electronic speed limiter
Your vehicle may be factory equipped with ti res
that are rated for a maximum speed of 130 mph
(210 km/h) . T his is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tir e speed rat ing . For more information
~page 221.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢4 will illuminate . If this occurs,
contact the nearest a utho rized Audi dealer for as­
sistance .
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions . Never drive your
vehicle faster than the maximum speed rating of the tires installed.
Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You will hear a warning tone when your speed ex­
ceeds the stored value by approximately 3 mph
(3 km/h) . Th e. (USA models)/. (Canada
models) indicator light and the message
Speed
limit exceeded!
appear in the instrument cluster
disp lay at the same time . The ./. indicator
light turns off when the speed decreases below
the stored maximum speed.
Setting a thresho ld is recommended if you would
like to be reminded when you re ach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
94
al speed limit or if there is a specified maximum
speed for winter tires.
(D Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit .
Setting the threshold
You can set, change and delete the threshold in
the MMI.
.. Select: the I MENU I button >Car> Systems*
contro l button > Driver assistance > Speed
warning.
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
· Description
Applies to vehicles: with cruise control system
The cruise control system makes it poss ible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modify ing engine
power or through an act ive brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation.
You are a lways responsible for your speed
and the distance between your vehicle and
other vehicles.
- For reasons of safety, cruise contro l should
not be used in the city, in stop-and-go traf­
fic, on winding roads and when road condi­ tions are poor (such as ice, fog, gravel,
heavy rain and hydroplaning) -you could
have an accident .
- Switch the cruise control off temporarily
when driv ing in turning lanes, highway exits
or in construction zones .

General information
Applies to vehicles: with Audi adaptive cruise control and Audi
pre sense front
Fig. 81 Front of vehicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*
r::!>page 103.
The radar sensor area r::!> fig. Bl must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap­
tive cruise control and the pre sense front. For in­
formation on cleaning, refer tor::!>
page 235. The
same applies for any modifications made in the
front area .
The function of the adaptive cruise control sys­ tem and pre sense front is limited in some condi­
tions :
- Objects can only be detected when they are
within the sensor ranger::!>
page 96, fig. 80.
-The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the side of your vehicle or moving into your lane.
- Objects that are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves
r=> page 98.
-With stationary objects r::!> page 98.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
r::!> page 103. As the d riv­
er, you are still responsible for starting and
for maintaining speed and distance to other objects. The pre sense front is used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi­
ble for braking at the correct time.
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
- 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 condi­
tions could result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations.
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and pre sense front will
have limited function.
- The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob­
jects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely. The adaptive cruise con­ trol cannot safely slow your vehicle or brake it to a stop if you are driving too close be­
hind a vehicle. Please note that the auto­
matic braking function cannot brake sud­
denly or apply the brakes fully under these
conditions.
- To reduce the risk of unintended actions,
switch the ACC off when you are not actively
using it.

The catalytic conve rter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi ­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine .
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in contact with dry grass, brush, fue l spill or
other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on o r near the exha ust man i­
fold, exhaust pipes, catalyt ic converte r or
heat s hields. Dur ing driv ing, the subs tance
u5ed for undercoating could overheat and
cause a fire .
(D Note
-Be awa re that just one tank f illing wit h lead­
ed
