power is not sufficient, the driver steering inter-
vention request will alert the driver using audio
and visual signals. Take over the steering and
keep your hands on the steering wheel so that
you will be ready to steer at any time. The system
will become inactive after a short time and will
only be active again later.
If the driver does not take over steering, adaptive
cruise assist will be canceled. If the vehicle is
equipped with emergency assist and it is ready to
function, it will be activated > page 190.

ZA WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.

@ Tips
— Always keep your hands on the steering
wheel. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— It is recommended to only switch on lane
guidance on well-constructed roads.
— Certain settings are stored automatically in
the active personal profile.
—The & fig. 131 button switches lane guid-
ance availability and the lane departure
warning on or off simultaneously, if lane

sist settings.
Setting the distance
Applies to: vehicles with adaptive cruise assist

B4M-0234



Fig. 132 Operating lever: setting the distance
If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.
> Tap the rocker switch to display the distance
that is currently set.
> To increase or decrease the distance in incre-
ments, tap the switch again toward G) or ().
The newly-set distance will be shown briefly, for
example with the indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 172,
fig. 128. The display matches the functions of
the indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise assist brakes to the set speed and
then maintains the set distance. If the vehicle
driving ahead accelerates, then the adaptive
cruise assist will also accelerate up to the speed
that you have set.
The following distances can be set:

sponsible for adhering to any applicable le-
gal regulations.
— Depending on the selected driving program
and distance, driving behavior when acceler-
ating may vary from moderate to sporty
= page 178, Adjusting the adaptive cruise

Lane departure warning
(erreur laced)
Applies to: vehicles with lane departure warning
The lane departure warning can detect lane
marker lines within the limits of the system. If
you are approaching a detected lane marker and
it appears likely that you will leave the lane, the
system can warn you with corrective steering and
a steering wheel vibration, if necessary.
The system functions in the speed range of ap-
proximately 40 mph - 155 mph (65 km/h -
250 km/h).
Applies to: vehicles with lane departure warning
and without side assist: The system will not warn
you before crossing a lane marker line if you have
activated the turn signal. In this case, it assumes
that you are changing lanes intentionally.
Applies to: vehicles with lane departure warning
combined with side assist: A noticeable corrective
steering movement will occur briefly before the
vehicle exits the lane if the turn signal is activat-
ed, the lane departure warning is ready, anda
lane change has been classified as critical by the
system due to vehicles traveling beside you or
due to approaching vehicles. This will attempt to
keep your vehicle in the lane.

The lane departure warning is ready to provide
warnings if an object is detected on at least one
side of the individual lane.
If the Hi indicator light turns on, the lane depar-
ture warning is not ready to provide warnings.
This may be due to the following reasons:
— The necessary lane marker lines have not been
detected (for example, in a construction zone
or because the lines are obstructed by snow,
dirt, water, or lighting)
— The speed is below the activation speed
— The lane is too narrow or too wide
— The curve is too narrow
— The driver's hands are not on the steering
wheel
— Visibility is obstructed by a rise or dip.
Steering intervention request
If no steering activity is detected or the steering
power from the system is not sufficient, the driv-
er steering intervention request will alert the
driver using audio and visual signals. Take over
the steering and keep your hands on the steering
wheel so that you will be ready to steer at any
time. The system will become inactive after a
short time and will only be active again later.
If the driver does not take over steering, the lane
departure warning will be switched off. If the ve-
hicle is equipped with emergency assist and it is
ready to function, it will be activated > page 190.
ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
— The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The
driver is always responsible for keeping
the vehicle within the lane.
— Corrective steering may not occur at all in
certain situations, such as during heavy
braking. Always be ready to intervene.

(i) Tips
— Always keep your hands on the steering
wheel. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.

Audi pre sense
Introduction
Applies to: vehicles with Audi pre sense
Within the limits of the system, the Audi pre
sense functions can initiate measures in certain
driving situations to protect the vehicle occu-
pants and other road users. Depending on the ve-
hicle equipment, various Audi pre sense systems
may
be installed:
— Audi pre sense basic can react during emergen-
cy and dangerous braking maneuvers and un-
stable driving situations (such as oversteering
or understeering).
— Audi pre sense front”) can detect an impending
frontal impact and react with warnings, braking
interventions, and preemptive safety measures
for the vehicle occupants.
— Audi pre sense rear monitors the rear traffic
behind your vehicle and can react to an impend-
ing rear impact.
— Audi pre sense side can detect an impending
side impact from cross-traffic and vehicles com-
ing from the side, and can initiate preemptive
safety measures.
— The swerve assist can assist during an evasive
maneuver recognized as critical with steering
movement and by braking individual wheels in-
dividually.
— The turn assist can detect vehicles in the oppo-
site lane and react with braking maneuvers.

D_ This is not available in some countries.
