NOTE The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".
In addition to the camera and radar sensor, the
function also uses the vehicle's rearward-facing
radar, which has certain general limitations the
driver should be aware of. See additional informa-
tion in the section "BLIS limitations".

390 Park Assist*
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating
distances to obstacles using audible signals and
graphics in the center display. Display view showing obstacle zones and sensor sec-
tors.
The center display shows an overview of the vehi-
cle in relation to objects that have been detected.
The marked sector indicates where the obstacle
is located. The closer the vehicle symbol is to a
marked sector forward/rearward, the closer the
detected obstacle is to your vehicle.
The side sectors change color as the distance
between the vehicle and an object decreases.
The audible signals will also speed up the closer
the obstacle is to the vehicle. The volume of the
audio system will be automatically lowered. Audible signals for obstacles in front and to the
sides of the vehicle are active when the vehicle is
moving but will cease after the vehicle has been
stationary for approx. 2 seconds. Audible signals
for obstacles behind the vehicle will remain active
even when the vehicle is stationary.
If a detected obstacle is within approx. 30 cm
(1 ft) from the front or rear of the vehicle, the
tone will become constant and the active sen-
sor's field closest to the vehicle symbol will be
filled in.
At distances within approx. 25 cm (0.8 ft) from an
obstacle to the sides of the vehicle, an rapid puls-
ing signal will be given and the active sector
fields will change color from ORANGE to RED.
The volume of the Park Assist audible signals
can be adjusted while the signal is being given
using the >II knob or in the center display's Top
view under Settings.
NOTE
Besides in the sector closest to the vehi-
cle symbol, audible warnings are only pro-
vided for objects located directly in the
vehicle's path.
WARNING
The Parking Assist function is supple-
mentary driver support intended to facili-
tate driving and help make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.
The parking sensors have dead/blind
spots where objects cannot be detected.
Pay particular attention to people and
animals near the vehicle.
Parking Assist is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

Park Assist front, rear and sides
Park Assist has different parameters depending
on which part of the vehicle is approaching an
obstacle.
Front camera Continuous tone warning signal when the obstacle is
less than approx. 30 cm (1 ft) from the vehicle
112
.
Park Assist's front sensors are automatically acti-
vated when the engine is started. They are active
at speeds below 10 km/h (6 mph).
The distance monitored extends approx. 80 cm
(2.5 ft) in front of the vehicle.
NOTE The Parking Assist system is deactivated
when the parking brake is applied or when P
is selected on vehicles with automatic trans-
mission.
CAUTION
When installing auxiliary lights: Make sure
these do not obscure the sensors – the auxili-
ary lights could be perceived as an obstacle.
Back
Continuous tone warning signal when the obstacle is
less than approx. 30 cm (1 ft) from the vehicle
112The rear sensors will be activated if the vehicle
begins rolling backward or if reverse gear is
engaged.
The distance monitored extends
approx. 1.5 meters (5 ft) behind the vehicle.
The Parking Assist system's rear sensors will be
automatically deactivated if the vehicle is backing
up with a trailer connected to the vehicle's elec-
trical system.
NOTE
When reversing with e.g. a trailer or bike car-
rier on the trailer hitch – without Volvo original
trailer cables – the Parking Assist system may
have to be turned off manually to prevent the
sensors from reacting to these.

Side sensors Rapid pulsing warning signal when the obstacle is less
than approx. 25 cm (0.8 ft) from the vehicle
112
.
Park Assist's side sensors are automatically acti-
vated when the engine is started. They are active
at speeds below 10 km/h (6 mph).
The distance monitored is approx. 25 cm (0.8 ft)
out from the sides.
The detection area increases significantly when
the steering angle of the front wheels increases
and depending on the steering wheel position,
obstacles up to approx. 90 cm (3 ft) directly
behind or in front of the vehicle can be detected
(also see “Side sensor fields” in the section “Sen-
sor field from Park Assist for Park Assist Cam-
era”).Related information

Park Assist limitations
Park Assist may not be able to detect all condi-
tions in all situations and functionality may there-
fore be limited in certain cases.
The driver should be aware of the following limi-
tations for Park Assist:
WARNING Be extra cautious when
reversing if this symbol is
shown when a trailer, bike
carrier or similar is attached
and electrically connected
to the vehicle.
The symbol indicates that
the rear parking assist sensors are deacti-
vated and will not warn of any obstacles.
CAUTION Objects such as chains, thin and glossy poles
or low obstacles may end up in the "signal
shadow" and then go temporarily undetected
by the sensors – the pulsating tone may then
unexpectedly stop instead of becoming a
constant tone as expected.
The sensors cannot detect high objects, such
as protruding ramps.
In such situations, pay extra attention and
maneuver/drive the vehicle very slowly or
stop the current parking maneuver –
there may be a high risk of damage to
the vehicle or other objects since infor-
mation from the sensors is not always
reliable in such situations.
CAUTION In some circumstances, the Park Assist Sys-
tem may produce false warnings due to exter-
nal sound sources with the same ultrasonic
frequencies as those the system works with.
Examples of such sources are horns, wet tires
on asphalt, pneumatic brakes, exhaust noise
from motorcycles, etc.
NOTE When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch pro-
trusion is included when the function meas-
ures the distance to objects behind the vehi-
cle.
