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

when reverse gear is engaged or can be started
manually using one of the center display's func-
tion buttons.

Start the Park Assist Camera
using this button in the center
display's Function view.
The screen will first show the
most recently used camera
view. However, each time the
engine is started, the previous side view will be
replaced by the 360° view and a previously dis-
played zoomed-in rear view will be replaced by
the regular rear view.
Automatically deactivating the cameraFront view switches off when the vehicle's speed
reaches 25 km/h (16 mph) to help avoid dis-
tracting the driver. It will be automatically reactiva-
ted if the vehicle's speed falls below 22 km/h
(14 mph) within 1 minute as long as the vehicle's
speed has not exceeded 50 km/h (31 mph). Other camera views switch off at 15 km/h
(9 mph) and are not reactivated.

DRIVER SUPPORT
408Parking with Park Assist Pilot
Park Assist Pilot (PAP 124
) helps the driver park
using three different steps. The function can also
help the driver pull out of a parking space.
NOTE The PAP function measures the space and
steers the vehicle – the driver's role is to:
keep close watch of the area around the
vehicle
follow the instructions on the center dis-
play
change gears (reverse/forward) – a
"ping" sound indicates when the driver
should change gears
regulate and maintain a safe speed
apply the brakes and stop. Information about the actions required by the
driver are provided in the center display using
symbols, graphics and/or text.
PAP can be activated if the following criteria have
been met after the engine is started:

No trailer is hitched to the vehicle
Your vehicle's speed is lower than 30 km/h
(20 mph).
NOTE The distance between the vehicle and parking
spots should be 0.5-1.5 meters (1.6-5.0 ft)
when PAP is looking for parking.
ParkingPAP parks the vehicle using the following steps:
1. The system searches for and measures
potential parking spaces.
2. The vehicle is steered while it is backing into the parking space.
3. The vehicle is positioned in the parking space (the driver may be prompted to shift
gears).
Searching for and measuring potential
parking spots
The function can be activated
in the center display's Function
view.
It can also be accessed from
the camera views. Parallel parking overview.
Perpendicular parking overview.

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.

Charging cable handle and charging socket.
Charging status is indicated in three ways:
The indicator lights in the charging module
(the unit connected to the wall outlet).
Indicator light in the vehicle's charging
socket.
Images and text in the instrument panel.
The start battery is charged while the hybrid bat-
tery is charging and stops charging when the
hybrid battery is fully charged.
If the hybrid battery's temperature is below
-10 ºC (14 ºF) or above 40 ºC (104 ºF), some of
the vehicle's functions may be reduced or not
available at all.
The electric motor cannot be used if the battery's
temperature is too low or too high. If the PURE
drive mode is selected, the gasoline engine will
start.
Charging using the gasoline engine The vehicle generates electrical current to charge the
battery, e.g. when the driver lightly presses the brake
pedal or when engine braking is used on downgrades.
The vehicle can also generate current to the
hybrid battery to charge it.
The hybrid battery can also be recharged by
lightly depressing the brake pedal, i.e. during
light braking. This converts the vehicle's
kinetic energy to electrical energy, which is
used to charge the hybrid battery.
In gear position B, the electric motor brakes
the vehicle when the accelerator pedal is
released and the hybrid battery is recharged
at the same time.
The combustion engine can also help
recharge the hybrid battery.Related information
