The tone becomes constant when you are within
approximately 1 ft (30 cm) of an object and the
innermost sensor field will be red. If there are
objects within this distance both behind and in
front of the vehicle, the tone alternates between
front and rear speakers.
While an audible signal is being given, its volume
level can be raised/lowered using the >II control
in the center console or can be adjusted in the
Setting menu.
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to be
a supplementary aid when parking the vehicle.
It is not, however, intended to replace the driv-
er's attention and judgement.
Rear park assist
300
The system's rear sensors are activated automat-
ically when the engine is started and are active if
the vehicle rolls rearward with the gear selector
in N or if R has been selected.
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The audible signal
comes from the rear speakers.
The rear sensors will be deactivated automatically
when towing a trailer if Volvo genuine trailer wir-
ing is used. If a non-Volvo trailer hitch is being
used, it may be necessary to switch off the sys-
tem manually.
Side park assist
The system's side sensors are activated automat-
ically when the engine is started and are active at
speeds below approximately 6 mph (10 km/h).
The distance monitored along the sides of the
vehicle is approximately 1 ft (0.3 m). The audible
signal comes from the side speakers.
Front park assist
The system's front sensors are activated auto-
matically when the engine is started and are
active at speeds below approximately 6 mph
(10 km/h).
The distance monitored in front of the vehicle is
approximately 2.5 ft (0.8 m). The audible signal
comes from the front speakers.
Front Park Assist is deactivated if the parking
brake is applied or if the gear selector is put in P.
When installing auxiliary headlights, be sure that
they do not obstruct the front sensors. Otherwise,
these lights could trigger a Park Assist warning.
