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 city and Audi pre sense front
can detect an impending frontal impact and re-
act with warnings, braking interventions, and
preemptive safety measures for the vehicle oc-
cupants.
— Audi pre sense rear monitors the rear traffic
behind your vehicle and can react to an impend-
ing rear impact.
— The swerve assist can help you to steer the ve-
hicle around an obstacle during an evasive ma-
neuver that is detected as critical.
— The turn assist can detect vehicles in the oppo-
site lane as critical during a turning maneuver
and react with braking maneuvers.

Depending on the vehicle speed and the vehicle
equipment, the following functions may be initi-
ated in certain situations:
— Visual and audio warnings
— Reversible tensioning of safety belts
— Closing the windows and panoramic glass roof

You can adjust the side assist to your preferences.
The settings depend on the vehicle equipment.
> Applies to: MMI: Select on the home screen:
VEHICLE > Driver assistance > Side assist.
Possible settings:
The system can be switched on and off. If the sys-
tem is switched on, the displays in the exterior
mirrors will turn on briefly each time the ignition

Brightness - Change the brightness only when
side assist is switched on, so that the selected
setting can be checked in the exterior mirror dis-
plays. Adjust the brightness to a level where the
display will not interfere with your view ahead.
Because the display brightness automatically
adapts to the ambient light, it may have already
been adjusted to the highest or lowest setting
during the automatic adaptation.
@ Tips
— If you switch side assist on or off, the exit
warning will also switch on or off.
— Certain settings are automatically stored
and assigned to the remote control key be-

ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.



@) Note
— Keep enough distance from the curb to
avoid damage to the rims.
— Applies to: vehicles with park assist: If you
park in short parking spaces using park as-
sist, a continuous tone will sound from the
parking aid when the distance to an object is
less than approximately 0.7 feet (0.20 m).

152
G) Tips
— The segments in the side area* are detected
and analyzed when passing. If you switch
the ignition off and on again or open the
door, or if the vehicle is stationary for a peri-
od of time, the surrounding area may have
changed in the meantime. In this scenario,
the side area* will appear black until the
area has been detected and evaluated.
— If the distance to an obstacle remains con-
stant, the volume of the distance warning
gradually lowers after a few seconds until it
is muted (this does not apply to the continu-
ous tone). If the obstacle comes closer than
it was before the sound was muted, the
tone will sound again. If the obstacle be-
comes farther away than it was before the
sound was muted, no tone will sound. Pay
attention to the vehicle's surroundings
when you start to drive.
