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.

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.
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.
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.

BLIS*
The BLIS
74
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.

The BLIS button in the center display's Func-

function.
BLIS overview
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
signal on the side in which the warning has been

given, the indicator light will become brighter and
begin flashing.
The light illuminates on the side of the vehicle
where the system has detected the vehicle. If
the vehicle is passed on both sides simulta-
neously, both lights come on.
WARNING
•
The BLIS function is supplementary driver
support intended to facilitate driving and
help make it safer – it cannot handle all
situations in all traffic, weather and road
conditions.
•
The responsibility for changing lanes
safely and using good judgment always
rests with the driver.
•
BLIS is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle 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.

BLIS limitations
BLIS

functionality may be reduced in certain
situations.
Keep the marked area clean (on both the left and right
sides of the vehicle)

.
Examples of limitations:
•
Dirt, ice and snow covering the sensors may
reduce functionality and prevent the system
from providing warnings.
•
The BLIS function is automatically deacti-
vated if a trailer, bicycle holder or similar is
connected to the vehicle's electrical system.
•
For BLIS to function optimally, bicycle hold-
ers, luggage racks or similar should not be
mounted on the vehicle's towbar.
WARNING
•
BLIS does not work in sharp curves.
•
BLIS does not work when the vehicle is
being reversed.

Recommended maintenance for
BLIS
•
For optimal performance, it is important to
keep the areas in front of the sensors clean.
•
Do not attach any objects, tape or decals to
the surface of the sensors.
Keep the marked area clean (on both the left and right
sides of the vehicle)

.
The BLIS sensors are located on the inside of
each of the rear fenders/bumpers and are also
used by the Cross Traffic Alert (CTA) and Rear
Collision Warning functions.
Repair of BLIS and CTA components or
repainting of the bumper may only be per-
formed by a workshop – an authorized Volvo
workshop is recommended.

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.

•
The responsibility for reversing the vehicle
safely and using good judgment always

Cross Traffic Alert is not a substitute for
the driver's attention and judgment. The

CTA
87
functionality may be reduced in certain
situations.
CTA does not function optimally in all situations
and has certain limitations. The CTA sensors, for
example, cannot "see" through other parked
vehicles or objects blocking the vehicle.
Below are a few examples of situations in which
CTA's field of vision may be initially limited and
approaching vehicles may therefore not be
detected until they are very close to your vehicle:
The vehicle is parked very far into a parking space.
In a diagonal parking space, CTA may be completely
"blind" on one side of your vehicle.

CTA's field of vision.
However, as you back your vehicle slowly out of a
parking space, CTA's field of vision changes in
relation to the obstructing vehicle/object and its
blind zone is reduced.

When RSI has registered a speed limit sign, the
sign will be displayed as a symbol in the instru-

in the speedometer's speed scale.
If the vehicle is equipped with Sensus
Navigation*, speed-related information will also
be retrieved from map data, which means that the
instrument panel can display or change informa-
tion about speed limits even if the vehicle has not
passed a speed-related sign.
