sense basic, the front safety belts are also re-
versibly tensioned when needed. The pre sense
front is also active when adaptive cruise con-
trol* is switched off.
ZA\ WARNING
Also follow the general instructions found in
= A in General information on page 119.
G) Tips
— Certain pre sense functions switch off when
driving in reverse.
— The pre sense functions may not be availa-
ble if there is a malfunction in the ESC sys-
tem or the airbag control module.
— Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated.
— Certain Audi pre sense front functions are
unavailable or have limited availability for
approximately 20 seconds after starting the
vehicle (may be longer depending on the
driving situation).
— Switch the pre sense off when you are not
using public streets or when loading the ve-
hicle onto a vehicle carrier, train, ship, or
other type of transportation. This can pre-
vent an undesired intervention from the pre
sense system.
ONT ees
Applies to: vehicles with Audi pre sense basic
The pre sense basic functions are activated at a
speed of approximately 20 mph (30 km/h) or
higher.
The following functions can be triggered under
certain conditions within the limits of the sys-
tem:
—Tensioning of the safety belts (for example,
during heavy braking): the front safety belts
have reversible belt tensioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
— Initiating the closing of the windows and the
panoramic glass roof* (for example when un-
der- or oversteering).

Description
Within the limits of the system and depending
on the situation and speed, pre sense front can
warn you about impending collisions with sta-
tionary, stopped, and moving vehicles and ini-
tiate appropriate braking measures.
If detection is not possible, then pre sense front
does not react.
The following functions trigger in conjunction
with pre sense basic at corresponding vehicle
speeds:
— Reversible tensioning of the front safety belts
— Closing the windows and panoramic glass roof*
Early warning/acute warning
The system can provide visual and audible warn-
ings when dangerous situations are detected. The
early warning may occur if:
—a vehicle driving ahead brakes strongly,
— your vehicle is traveling at speeds between ap-
proximately 20 to 50 mph (30 to 85 km/h) and
it approaches a stationary vehicle.
— your vehicle is traveling at speeds between ap-
proximately 20 to 155 mph (30 to 250 km/h)
and it approaches a vehicle that is clearly trav-
eling more slowly or a vehicle in your direction
of travel that is stopped.
When this warning occurs, it may only be possi-
ble to avoid a collision by swerving or braking >
