Ass is t
The stored speed and the [ij;ji j~i4 (USA models)/
Ill (Canada mode ls) indicator light appear in the
instrument cluster disp lay . An add itiona l indica­
tor appears in the Head -up display*.
The speed is maintained by modifying engine power or through an active brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control system is in op­
eration. You are always responsible for your
speed and the distance between your vehi­
cle and other veh icles .
- 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
poo r (such as ice, fog, gravel, heavy rain and
hydroplaning), because t his increases the
risk of an accident.
- Switch the cruise cont rol off temporar ily
when d riving i n turn ing lanes, h ighway exits
or in construction zones .
- Please note tha t unconsciously "resting"
yo ur foot on the accelerator pedal prevents
the cruise control from braking. This is be ­
cause pressing the acce lerato r pedal ove r­
rides the cruise contro l system.
- If a brake system ma lf u nction such as over ­
heating occurs when the cruise control sys­
tem is sw itched on, the braking function in
the system may be sw itched off. The rest of
the cruise control system functions remain
active as long as the
[ij;(l)~i4 (USA models) I
i:I (Canada models) indicator light is on.
(D Note
Before driving a long d istance on a steep
downward hill, decrease your speed and se­
lect a lower driving gea r. This makes use of
the engine b raking effect and relieves the
brakes.
(0 Tips
The b rake lights turn on when the brakes are
app lied automatically .

Audi pre sense city
' Description
App lies to : vehicles wit h Audi pre sense city
Within the limits of the system, pre sense city
can warn you of impending collisions with
vehicles and pedestrians and initiate the applica­
ble braking maneuver if needed. Pre sense city is
active at a speed of 6 mph (9 km/h) and higher.
A pedestrian warning can occur at speeds up to 50 mph (85 km/h), and vehicle warnings can oc­
cur at speeds up to 155 mph (250 km/h). A pre
sense city braking maneuver is possible at speeds
up to 50 mph (85 km/h).
Warnings
App lies to: vehicles wit h Aud i pre sense city
The system recognizes various dangerous situa­
tions. The
early warning occurs when:
- a vehicle driving ahead brakes sudden ly,
- your own vehicle approaches a sign ificantly
slower vehicle or stationary vehicle in the direc­
tion of travel.
- a pedestrian is standing in the lane or is moving
into the lane.
When this warning occurs, it may only be possi­
ble to avo id a collision by swerving or braking
strongly. The message
Audi pre sense.
~ page 108, fig. 104 and a warning tone will
warn you about the danger.
Additionally, a jerk on the brakes may occur as an
acute warning when there is an impend ing colli­
sion . If you do not react to the acute warning, pre
sense city can brake to the point of complete de­
ce leration within the limits of the system. This
reduces the vehicle speed in the event of a colli­
sion. The message
Audi pre sense. also ap­
pears.
The following functions are triggered in conjunc­
tion with pre sense basic/rear:
- Reversible tensioning of the front safety belts .
- Closing the windows and sunroof*. ..,

A WARNING -,..___
-Pre sense city cannot overcome the laws of
physics. It is a system designed to assist and
it cannot prevent a collision in every circum­
stance. The driver must always intervene.
The driver is always responsible for braking at the correct time . Do not let the increased
safety provided tempt you into taking risks.
This could increase your risk of a collision .
- The system can deploy incorrectly due to
system-specific limits.
- To reduce the risk of an accident, please
note that the camera does not always detect
every object .
- Pre sense city does not react to animals,
crossing or oncoming vehicles, objects such
as bars, railings or railcars, and objects that
are difficult to detect~&.
in General infor­
mation on page 97.
A WARNING
Pre sense city may be restricted or not availa­
ble in the following example situations:
- in heavy fog, rain, spray or snow.
- when there are visual obstructions, such as
glare, reflections or var iations in light.
- when it is dark .
- if the camera window or the windshield is
dirty, iced over, damaged or covered .
- when driving on snow, ice or loose ground .
- on sharp curves.
- if the ESC was restricted or switched off .

Audi active Lane assist
Description
Applies to: veh icles w ith Audi active lane assist
Active lane assist (lane departure warning) de­
tects lane ma rker lines withi n the l imits of the
system using a camera in the windshield. If you
are approaching a detected lane marker line and it appears likely that you will leave the lane, the
system will warn you w ith corrective stee ring .
You can override this steering at any time . If you
112
pass over a line, the steering wheel will vibrate
lightly. In order for this warning vibration to oc­
cur, it must first be switched on in the Infotain­
ment system. Active lane ass ist is ready for oper­
a tion when the lane marker line is detected on at
least one side of the vehicle .
T he system is des igned for driving on express­
ways and highways and therefore on ly activates
a t speeds above approximately 40 mph (65 km/
h) .
Applies to vehicles with s ide ass ist*: if you acti­
vate a turn signa l when active lane assist is ready
a nd it classifies a lane change as critical bec ause
of veh icles traveling a longside you or approach ­
i ng you, there will be noticeable corrective steer­
i ng shortly before you leave the lane. This will at­
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist* : the sys ­
tem does not warn when it is ready if you act ivate
the turn signal before crossing the lane marker
lin e. In this case, it assumes that you are chang­
in g lanes intent ionally.
Applies to vehicles with adaptive cruise contro l*:
there is no corrective steer ing or warnings if the
system recognizes a distinct passing maneuver.
If the conditions are met, congestion assist
switches on at speeds under approximately
40 mph (65 km/h)
¢page 104.
_& WARNING
-The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
