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 >

Activating rear cross-traffic assist
The rear cross-traffic assist is activated automati-
cally if you turn on the parking aid > page 136 or
shift into reverse gear.
The rear cross-traffic assist can warn the driver of
a potential collision with approaching cross-traf-
fic when driving in reverse at speeds up to ap-
proximately 7 mph (12 km/h). Within its limits,
the system monitors the areas behind and next
to the vehicle using the radar sensors when leav-
ing a parking space > page 132, fig. 127. Moving
objects that are approaching, such as cars, are
detected > fig. 128.
If the system detects critical cross traffic when
backing out of a parking space, it will react as fol-
lows:
134
— Visual indicator: an indicator appears in the In-
fotainment system display with a red arrow
symbol. The arrow points in the direction from
which the object is approaching > fig. 129.
— Audible warning signal: a continuous tone may
sound as an additional indicator when driving in
reverse.
— Automatic brake activation: a brief activation
of the brakes may also warn you of a potential
collision with an approaching object.
The audible warning signal and the automatic
brake activation occur only when driving in re-
verse.

iN WARNING
—The rear cross-traffic assist is an assist sys-
tem and cannot prevent a collision by itself.
The driver must always intervene. The driver
is always responsible for braking at the cor-
rect
time.
— Please note that the rear cross-traffic assist
may activate the brakes unexpectedly. Se-
cure any cargo that you are transporting to
reduce the risk of damage or injury.
— An additional brake activation may be trig-
gered within 10 seconds after an automatic
brake activation.
—If there is an acoustic warning signal from
the rear cross-traffic assist, then the parking
system may not warn you of detected obsta-
cles under certain circumstances.
— The view of the radar sensors may be im-
paired by leaves, snow, heavy spray or dirt.
Clean the area in front of the sensors
=> page 132, fig. 127.

ZA WARNING
— The rear cross-traffic assist will not provide
alerts about people and cannot warn you
about every type of approaching objects,
such as cyclists. Always monitor the traffic
as well as the vehicle's surroundings with di-
rect eye contact.
— The rear cross-traffic assist will not provide
alerts if your vehicle is parallel or diagonally

— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the engine com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the anti-freezing agent con-
tained in the coolant) can ignite.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.


1) Depending on the engine and country
304


— Never open the hood when there is steam or
coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
Plug-in hybrid drive: the coolant expansion
tank cap is equipped with a seal that must
never be removed under any circumstances
=> page 312, fig. 251. If the coolant expan-
sion tank for the high-voltage system is not
sealed, please contact an authorized Audi
dealer or authorized Audi Service Facility.
Plug-in hybrid drive: the sealed cap must on-
ly be opened by an authorized Audi dealer or
authorized Audi Service Facility.
The cap on the coolant expansion tank must
never be opened as long as the coolant is
hot. The cooling system is under pressure.
There is a risk of burns
To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“p” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
