Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay be-
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly. The ow in-
dicator light will appear at the same time in the
instrument cluster display along with a message.
The fe) indicator light and the message turn
off if the speed falls back below the stored maxi-
mum 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 gener-
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning threshold

> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Driver as-
sistance > Speed warning > Manual.
G) 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.
Messages
Applies to: vehicles with speed warning system
Manually set speed limit XX mph
(km/h) exceeded

The stored speed was exceeded.
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
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 conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
@) Note
— Conventional drive system: before driving
downhill a long distance on a steep hill, de-
crease your speed and select a lower gear.
This makes use of the engine braking effect
and reduces the load placed on the brakes.
— Plug-in hybrid drive: before driving downhill
a long distance on a steep hill, decrease
your speed and use the recuperation braking
effect > page 78. This reduces the load on
the brakes.
(i) Tips
The brake lights turn on when the brakes are
applied automatically.

Requirement: the system must be switched on
and activated.
Overriding
> To temporarily override the cruise control
speed, press the accelerator pedal.
> Once you release the accelerator pedal, the sys-
tem will adjust back to the stored cruise control
speed.
If you override the cruise control system for a
long period of time, the cruise control system
will be deactivated. The ICRUISE| or indicator
light will be displayed and the cruise control
speed will be saved.

B - Adaptive cruise control must be switched
on. No vehicles are detected ahead. The stored
speed is maintained.
B - Avehicle driving ahead was detected. The
adaptive cruise control system regulates the
speed and distance to the vehicle ahead and
brakes/accelerates automatically.
B - Adaptive cruise control must be switched
on. A vehicle was detected ahead. Your vehicle re-
mains stopped and will not start driving auto-
matically.
B - The automatic braking is not enough to
maintain a sufficient distance to a vehicle driving
ahead. You must intervene > page 124, Driver in-
tervention request.
@ Instrument cluster display
If adaptive cruise control is not shown in the in-
strument cluster display, you can call it up using
the multifunction steering wheel buttons
=> page 17.
Based on the graphics in the display, you can de-
termine if the system is maintaining a distance to
a vehicle ahead and what that distance to this ve-
hicle is:
No vehicle - No vehicle was detected driving
ahead.
Silver vehicle - A vehicle was detected driving
ahead.
Red vehicle - Request for driver intervention
=> page 124.
The five distance bars on the gauge (4) represent
the set distance (refer to > page 123 for infor-
mation on how to change the distance). If you
fall below the selected distance, the distance
bars become red from the bottom upward.

ZA\ WARNING
If you press the [SET] button when driving at
speeds below 20 mph (30 km/h), the vehicle
accelerates automatically up to 20 mph (30
km/h), which is the minimum speed that can



be set.

@) Tips
— If you switch the ignition or the adaptive
cruise control system off, the set speed is
erased for safety reasons.
— The Electronic Stabilization Control (ESC)
and the Anti-Slip-Regulation (ASR) are auto-
matically switched on when the adaptive
cruise control is switched on.

Audi pre sense
Introduction
Applies 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-
tive occupant protection are can be initiated.
— The pre sense front uses the data from the ra-
dar sensors and calculates the probability of an
accident > page 119. An impending collision
with vehicles can be detected within the limits
of the system. In this case, the system warns
the driver visually, acoustically and with a jerk
on the brakes if necessary. If needed, it can ini-
tiate a partial or full deceleration to reduce the
collision speed or to avoid the collision under
certain circumstances. In conjunction with pre >
