Speed warning system
Introduction
The speed warning system helps you to stay
under 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 exceeds the stored value by ap­ proximately 3 mph (3 km/h). An indicator
light . (USA models) . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns
off when the speed decreases below the
stored maximum speed .
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you may want to do so include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
"' Select: Systems or Car systems > Driver as­
sist> Speed warning .
Driving 79
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 possible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
.&_ WARNING ~
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on winding roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
planing) -you could have an accident.
- Switch the cruise control
off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking.
This is due to the control system being
overridden by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models) !l'I (Canadian models)
ison.
~ •

A WARNING ,~
You should only resume the stored speed if
it is not too high for existing traffic condi­
tions . Otherw ise you risk an accident.
- If the brakes become too heated while
driving, the cruise control switches off. If
th is happens while dr iving downh ill, you
can relieve the brakes by shifting into a
lower gear.
- When the cruise control is act ivated, ESC
sport mode cannot be switched on . Driving 81

90 Audi pre sense
Audi pre sense
Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre
sense front
Within the limits of the system, pre sense ba­
sic and pre sense front can initiate steps to
protect vehicle occupants in certain danger ­
ous situations.
Critical driving situations can be recognized by
the pre sense front via a network of different
vehicle systems and can take steps to prepare
the vehicle occupants for a potential collision.
The pre sense front works with a radar sensor
and a video camera*.
It also functions within
the limits of the system when adaptive cruise
control* is switched
off.
General information

App lies to vehicles: with Audi pre sense front or Audi
adaptive cruise control
A WARNING
Also follow the general information found
on
~ page 82, General information.
Audi pre sense basic
Descript ion
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activat­
ed at a speed of 10 mph (30 km/h) or higher.
The following functions can be triggered un­
der certain conditions within the limits of the
system:
- Tensioning of the safety belts (for example,
during heavy braking) : The front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to trigger again .
- Closing the windows and the sunroof* (for
example, when over- or understeering): The
windows and the sunroof" close until there is only a small gap open. Audi drive select:
The deployment time is
adapted in dynamic mode.
A WARNING
-The pre sense basic cannot overcome natu- ral physical laws.
It is a system designed to
assist and it cannot prevent a collision. Do not let the increased safety provided
tempt you into taking risks. This could in­
crease your risk of a collision.
- The system can deploy incorrectly due to system-specific limits .
(D Tips
-Certain pre sense basic functions switch
off when ESC is switched off (sport
mode) or when driving in reverse .
- The pre sense basic functions may not be
available if there is a malfunction in the
ESC system or the airbag control mod­
ule .
- Note that with pre sense basic, the rever­
sible safety belt pretensioner on the
front passenger's side deactivates when
the front passenger's a irbag is deactivat­
ed.
Audi pre sense front
Description
Applies to vehicles: with Audi pre sense front or Audi
adapt ive cru ise control
Pre sense front informs you if the distance to
the vehicle ahead falls below the safe distance
for an extended period of time. It can warn of a possible collision and initiate braking ma­
neuvers, within the limits of the system .
When detected in time, the system can assess
dangerous situations where an object ahead
brakes suddenly or if your own vehicle is trav­
eling at a high speed and approaching an ob ­
ject that is moving more slow ly . If detection is
not possible, then pre sense front does not re ­
act.

Automatic
transmission S tronic-transmission
Introduction
Applies to vehicles: with S tronic transmiss ion
Your vehicle is equipped with an electronical­
l y -controlled DSG transmission called S tronic.
T wo independent clutches transfer the power
between the engine and transmission. It al­
lows the vehicle to accelerate without a no­
ticeable interruption in traction .
T he transmission upshifts or downshifts auto­
matically. The driving style continuously influ­
ences the selection of the driving program .
When a
moderate driving style is used, the
transmission selects the most econom ica l
driving mode. The transmission upshifts at a
lower RPM and downshifts at a higher RPM to
improve fuel effic iency .
T he transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) r=> page 110,
Shifting manually (tiptronic mode) .

In the D/S selector lever position , the trans ­
mission can be operated either in the normal
D mode or in the S sport mode. To select the S
spor t mode, pull the selector lever back brief­
ly. Pulling the lever back again will select the
normal D mode . The instrument cluster dis­
play shows the selected driving mode.
In the
normal mode D, the transmission auto­
matically selects the suitable gear ratio . It de­
pends on engine load, vehicle speed and driv­
