Standby mode due to action by the driver
Pilot Assist will be temporarily deactivated and
put in standby mode if: the brakes are applied.
the gear selector is moved to N
a turn signal is used for more than 1 minute.
the vehicle is driven faster than the set
speed for more than 1 minute
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
When the turn signals are used, Pilot Assist's
steering assistance will be temporarily deacti-
vated. When the turn signal is switched off, steer-
ing assistance will be automatically reactivated if
the traffic lane's side markings can still be
detected.
Automatic standby mode
Pilot Assist is dependent on other systems, such
as Electronic Stability Control (ESC 61
). If any of
these other systems stops working, Pilot Assist
will automatically switch off.
WARNING With automatic standby mode, the driver is
warned by an acoustic signal and a message
on the instrument panel.

The driver must then regulate vehicle
speed, apply the brakes if necessary, and
maintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standby
mode if, e.g.:
the driver opens the door.
the brake temperature is high.
the driver's hands are not on the steering
wheel.
the parking brake is applied.
the engine speed (rpm) is too low/high.
the driver unbuckles the seat belt.
one or more of the wheels lose traction.
the camera/radar sensor is covered by snow
or heavy rain (the camera lens/radar waves
are blocked)
your vehicle's speed goes below 5 km/h
(3 mph) and Pilot Assist cannot determine if
the vehicle ahead is stationary or if it is
another object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Pilot Assist no longer has a vehicle to follow.
Reactivating Pilot Assist from standby
mode Note: This illustration is general and details may vary
depending on model.
To reactivate Pilot Assist:
–

Starting passing assistance with
Pilot Assist
Several conditions must be met for passing
assistance to be possible.
In order to activate passing assistance:
your vehicle must be following a vehicle
ahead (target vehicle)
your vehicle's current speed must be
at least 70 km/h (43 mph)
the set speed for Pilot Assist must be high
enough to safely pass another vehicle.
Starting parking assistanceTo start passing assistance:
–
Turn on the left turn signal.
>

Passing assistance will start.

limitations
Passing assistance functionality may be reduced
in certain situations.
WARNING The driver should be aware that if conditions
suddenly change when using Parking Assis-
tance, the function may implement an unde-
sired acceleration in certain conditions.
Some situations should be avoided, e.g. if:

the vehicle is approaching an exit in the
same direction as passing would normally
occur
the vehicle ahead slows before your vehi-
cle has had time to switch to the passing
lane
traffic in the passing lane slows down
a vehicle for right-hand traffic is driven in
a country with left-hand traffic (or vice
versa).
Situations of this type can be avoided by tempo-
rarily putting Pilot Assist in standby mode.

Assist
At certain speeds, models with automatic trans-
missions and

Pilot Assist can switch target vehi-
cles.
Switching target vehicles If the target vehicle ahead turns suddenly, there may be
stationary traffic ahead.
When Pilot Assist is actively following another
vehicle at speeds under 30 km/h (20 mph) and
switches targets from a moving vehicle to a sta-
tionary vehicle,

Pilot Assist will brake for the sta-
tionary vehicle.

WARNING
When Pilot Assist follows another vehicle at
speeds over approx. 30 km/h (20 mph) and
changes target vehicle – from a moving vehi-
cle to a stationary one – Pilot Assist will
ignore the stationary vehicle and instead
accelerate to the stored speed.
The driver must then intervene and apply
the brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standby
mode if:
your vehicle's speed goes below 5 km/h
(3 mph) and Pilot Assist cannot determine if
the target object is a stationary vehicle or
another object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Pilot Assist no longer has a vehicle to follow.

Pilot Assist (p. 316) Auto-hold braking with Pilot Assist
Pilot Assist has a special braking function in
slow traffic and at a standstill.
Braking function in slow traffic and at a
standstill
In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is stopped for less than
approx. 3 seconds. If it takes more than 3 sec-
onds for the vehicle ahead to begin moving again,
Pilot Assist will go into standby mode and the
Auto-hold brake function will activate.
– Pilot Assist can be reactivated by:
Pressing the button on the steering
wheel keypad.
Pressing the accelerator pedal.
>

Pilot Assist will resume following the vehi-
cle ahead if it begins to move within
approx. 6 seconds.
NOTE Pilot Assist can keep the vehicle stationary
for no more than 5 minutes – after that time
the parking brake is applied and the function
is deactivated.
The parking brake must be released before
Pilot Assist can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated
when the vehicle is at a standstill and Pilot Assist
will go into standby mode. This means that the
brakes will be released and the vehicle could
begin to roll. The driver must actively apply the
brakes to keep the vehicle stationary.
This can occur if:
the driver depresses the brake pedal
the parking brake is applied
the gear selector is moved to the P, N or R
positions
the driver puts Pilot Assist in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will be
applied to keep the vehicle at a standstill.
This occurs if Pilot Assist is keeping the vehicle
stationary using the brakes and:
the driver opens the door or unbuckles
his/her seat belt
Pilot Assist has kept the vehicle at a stand-
still for more than approx. 5 minutes
the brakes overheat
the driver switches off the engine manually.

360 Cross Traffic Alert*
CTA 82
is a supplementary driver support system
to BLIS 83
that is intended to help the driver
detect vehicles crossing behind the vehicle
while backing up. CTA overview.
CTA supplements BLIS by detecting traffic cross-
ing from the side, e.g. when backing out of a
parking space.
CTA is primarily designed to detect vehicles, but
in certain cases can also detect pedestrians or
smaller objects such as bicycles.
CTA is only active when the vehicle is moving
backward or if reverse gear is engaged. If CTA detects that something is approaching
your vehicle from the side:
an audible signal will sound from either the
left or right speaker, depending on which
side of your vehicle the object is approaching
from.
an icon will illuminate in the PAS 84
graphic
on the screen.
an icon will appear in the Park Assist Cam-
era's Top view. Illuminated CTA icon in the PAS graphic

screen.
WARNING
The Cross Traffic Alert function is supple-
mentary driver support intended to facili-
tate driving and make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
The responsibility for reversing the vehicle
safely and using good judgment always
rests with the driver.
Cross Traffic Alert 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 appropri-
ate distance to other vehicles, and in
accordance with current traffic rules and
regulations.

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.

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.

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.
