Passing assistance with Pilot Assist
Pilot Assist can assist the driver when passing
other vehicles.
How passing assistance worksWhen Pilot Assist is following another vehicle
and you indicate that you intend to pass that
vehicle by using the turn signal 67
, Pilot Assist will
begin accelerating toward the vehicle ahead
before your vehicle has moved into the passing
lane.
The function will then delay a speed reduction to
avoid early braking as your vehicle approaches a
slower-moving vehicle.
The function remains active until your vehicle has
passed the other vehicle.
WARNING Please note that this function can be acti-
vated in more situations than just passing
another vehicle, such as when a direction indi-
cator is used to indicate a lane change or
before exiting to another road – the vehicle
will then briefly accelerate.

Requirements for passing assistanceIn 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.

–
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.

Rear Collision Warning
The Rear Collision Warning (
RCW) function can
help the driver avoid rear-end collisions from
vehicles approaching from behind.
RCW is automatically activated each time the
engine is started.
RCW can warn the driver of a potential collision
with vehicles approaching from behind by rapidly
flashing the turn signals.
If, at a speed below 30 km/h (20 mph), the RCW
function detects that the car is in danger of being
hit from behind, the seatbelt tensioners may ten-
sion the front seatbelts and activate the Whiplash
Protection System safety system.
Immediately before a collision from behind, RCW
may also activate the foot brake in order to
reduce the forward acceleration of the car during
the collision. However, the brakes will only be
applied if your vehicle is stationary. The brakes
will be immediately released if the accelerator
pedal is depressed.
Related information
• Rear Collision Warning limitations (p. 347)
• Whiplash Protection System (p. 46) Rear Collision Warning limitations
In some situations, it may be difficult for RCW to
warn the driver of a collision risk. This may be the case if:
• the vehicle approaching from the rear is
detected at a late stage
• the vehicle approaching from the rear
changes lanes at a late stage
• the vehicle approaching from the rear is mov-
ing at a speed above 80 km/h (50 mph)
• a trailer, bicycle holder or similar is con-
nected to the vehicle's electrical system - the
RCW function will then be automatically
deactivated.
NOTE In certain markets RCW does not warn with
the direction indicators due to local traffic
regulations – in such cases, that part of the
function is deactivated.
NOTE The warning with direction indicators for Rear
Collision Warning is deactivated if the colli-
sion warning distance in the City Safety func-
tion is set to the lowest level "
Late".
The seat belt tensioning and braking func-
tions remain active.

348 BLIS*
The BLIS 78
function is designed to help provide
assistance in heavy traffic with several lanes
moving in the same direction by helping the
driver to detect the presence of vehicles in the
"blind spot" area behind and to the side of the
vehicle.
BLIS is a driver support system designed to alert
the driver of:
• vehicles in your "blind spot"
• vehicles approaching rapidly in adjacent
lanes. Location of BLIS indicator light.

Blind spot zone
Rapidly approaching vehicle zone.
The BLIS function is active at speeds
above 10 km/h (6 mph).
The system is designed to react to: • vehicles passing your vehicle
• vehicles that are rapidly approaching your
vehicle from behind.
When BLIS

detects a vehicle in zone 1 or a rap-
idly approaching vehicle in zone 2, an indicator
light will illuminate in the relevant rearview mirror
and glow steadily. If the driver then uses the turn

Lane Keeping Aid does not intervene
Lane Keeping Aid does not intervene in sharp inside
curves.
In certain cases, such as when a turn signal is
used or when "straightening out" an inside curve,
Lane Keeping Aid will not provide steering assis-
tance or alerts.

Run-Off Mitigation with steering
assistance
This sub-function is intended to help reduce the
risk of the vehicle inadvertently running off the
road by actively steering the vehicle back onto
the road.
The function is active at speeds between
65-140 km/h (40-87 mph) on roads with clearly
visible traffic lane markings/lines.
The system uses a camera to monitor the edges
of the road and the painted side marker lines. If
the vehicle is about to cross the edge of the road,
the function will attempt to steer the vehicle back
onto the road. If this is not sufficient to keep the
vehicle on the road, the brakes will also be
applied.
However, the function will not provide either
steering assistance or braking if the turn signal is
used. The function will also not be activated if it
detects that the driver is actively operating the
vehicle.
After the system has automatically intervened,
this text message will appear in the instrument
panel: • Collision avoidance assistance –
Automatic intervention
WARNING •
The "Steering assistance at risk of run-
off" subfunction is supplementary driver
support intended to help improve driving
safety – it cannot handle all situations in
all traffic, weather and road conditions.
• The function cannot detect barriers, rails
or similar obstacles at the side of the
road.
• "Steering assistance at risk of run-off" 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 appropri-
ate speed, with an appropriate distance to
other vehicles, and in accordance with
current traffic rules and regulations.

If you become distracted and do not notice your
vehicle starting to veer out of the lane while
another vehicle is approaching from behind or is
in your vehicle's blind spot, this sub-function can
help provide assistance. The function provides assistance by steering your vehi-
cle back into your own lane.

If your vehicle is beginning to veer out of your
lane while another vehicle is in your blind spot or
another vehicle is rapidly approaching in the next

using a turn signal without noticing another vehi- cle approaching, the function can provide assis-
tance.

382Park Assist front, rear and sides
Park Assist has different parameters depending
on which part of the vehicle is approaching an
obstacle.
Back Note: This illustration is general and details may vary
depending on model.
The rear sensors will be activated if the vehicle
begins rolling backward or if reverse gear is
engaged.
The distance monitored begins
approx. 1.5 meters (5 feet) behind the vehicle.
The rear sensors will be automatically deactivated
if the vehicle is backing up with a trailer attached.
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
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 begins approx. 30 cm
(1 ft) from the sides. The audible signal for obsta-
cles along the sides of the vehicle is emitted
from the side speakers.
Front camera Note: This illustration is general and details may vary
depending on model.
Park Assist's front sensors are automatically acti-
vated when the engine is started. The front sen-
sors are active at speeds below 10 km/h
(6 mph).
The distance monitored begins 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.
