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.

Driver Alert Control (p. 370) Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be
reduced in certain situations.
In certain situations, the system may provide a
warning even if it has not detected a change in
driving behavior, e.g.:
in strong crosswinds
on grooved road surfaces.
WARNING In certain cases, driving behavior might not be
affected despite the driver's fatigue – when
using the Pilot Assist function – resulting in
the driver not getting a warning from DAC.
It is therefore very important to always stop
and take a break at the slightest sign of fati-
gue, regardless of whether the DAC function
has issued a warning or not.
NOTE
The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

Lane Keeping Aid (LKA 104
) is designed to
actively steer the vehicle on freeways, highways
and other major roads to help the driver reduce
the risk of the vehicle unintentionally veering out
of the lane.
Lake Keeping Assistance steers the vehicle back
into the lane and/or alerts the driver using vibra-
tions in the steering wheel.
Lane Keeping Aid is active at speeds between
65-200 km/h (40-125 mph) on roads with
clearly visible traffic lane marker lines.
On narrow roads, the function may be unavailable
and go into standby mode. The function will
become available again when the road becomes
sufficiently wide. A camera monitors the road/traffic lane's marker lines.

Park Assist Camera limitations
The Park Assist Camera may not be able to
detect all conditions in all situations and func-
tionality may therefore be limited.
The driver should be aware of the following limi-
tations for the Park Assist Camera:
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.
NOTE A bike carrier and other accessories mounted
on the rear of the vehicle can obscure the
camera's view.
Blind sectors There are "blind" sectors between the cameras' fields of
vision.
With 360° view selected, objects/obstacles may
not be detected if they are located in the "joints"
where the edges of the individual camera views
meet.
WARNING
Even if it seems as though only a fairly small
section of the screen image is obstructed, this
may mean that a relatively large sector is hid-
den and obstacles there may not be detected
until they are very near the vehicle.
Defective cameraIf a camera sector is dark and
contains this symbol, this indi-
cates that the camera is not
functioning properly.
See the following illustration for
an example. The vehicle's left-side camera is malfunctioning.
Dark camera sector
A dark camera sector may also be displayed in
the following situations, but without the defective
camera symbol:
a door is open
the tailgate is open
a rearview mirror is folded in

HYBRID INFORMATION
416General information about Twin
Engine
Twin Engine vehicles are driven just like any
other vehicle, but certain functions differ from a
vehicle powered exclusively by gasoline. The
electric motor powers the vehicle primarily at low
speeds; the gasoline engine is used at higher
speeds or during more active driving.
The instrument panel displays Twin Engine-spe-
cific information - charging information, selected
drive mode, distance to discharged battery and
hybrid battery charge level.
Different drive modes can be selected while driv-
ing, e.g. electric power only or, if more power is
needed, a combination of electric and gasoline
power. The vehicle calculates the optimal combi-
nation of driveability, driving experience, environ-
mental impact and fuel economy for the selected
drive mode.
In order to function optimally, the hybrid battery
(and its electrical drive systems) and the gasoline
engine (and its drive systems) must be at the
correct operating temperature. Battery capacity
can be considerably reduced if the battery is too
cold or too hot. Preconditioning prepares the
vehicle's drive systems and passenger compart-
ment before driving to help reduce both wear and
energy consumption. It also helps increase the
hybrid battery's range.
The hybrid battery which powers the electric
motor is recharged using the charging cable. It can also be recharged during light braking and
through engine braking in gear position B. The
combustion engine can also help recharge the
hybrid battery.
Important
No electrical current
Keep in mind that if there is no electrical current
to the vehicle, i.e. the ignition is switched off or
the start battery is discharged, certain functions
such as brakes, power steering, etc. will not work.
WARNING If the vehicle does not have electrical current
and both the electric motor and the gasoline
engine are switched off, the brakes cannot be
used to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind another
vehicle, as this could damage the electric motor.
Exterior engine noise
WARNING
Please be aware that there is no sound from
the engine when the vehicle is being powered
by the electric motor and it may be difficult to
detect by children, pedestrians, cyclists and
animals. This is especially true at low speeds.
High-voltage electrical current
WARNING A number of electrical components in Twin
Engine Plug-in Hybrid vehicles use high-volt-
age current and can be extremely dangerous
if handled incorrectly. These components and
any orange wiring in the vehicle may only be
handled by trained and qualified Volvo service
technicians.
Do not touch anything that is not clearly descri-
bed in this Owner's Manual.

In addition to the conventional fuel tank, your
vehicle is also equipped with a rechargeable
lithium-ion hybrid battery.
WARNING California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/
passenger-vehicle.
The hybrid battery can be recharged using the
charging cable stored in a storage space in the
cargo compartment.
WARNING The hybrid electrical system in your vehicle
uses high voltage electrical current. Any dam-
age to this system or to the hybrid battery
may result in the danger of overheating, fire,
or serious injury. If the vehicle is involved in a
collision or subjected to flooding, fire, etc.,
have it inspected by a trained and qualified
Volvo service technician. Prior to this inspec-
tion, the vehicle should be parked outdoors at
a safe distance from any building or poten-
tially flammable materials.
The hybrid battery's charging time depends on
the charging current used.
NOTE The capacity of the hybrid battery diminishes
somewhat with age and use, which could
result in increased use of the gasoline engine
and consequently, slightly higher fuel con-
sumption.
WARNING
If the hybrid battery needs to be replaced, this
may only be done by a Volvo retailer or
authorized Volvo workshop.
