may not be able to
detect all conditions in all situations and func-
tionality may therefore be limited.
WARNING •
The PAP 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.
• Pay particular attention to people and
animals near the vehicle.
• Bear in mind that the front end of the
vehicle may swing out towards oncoming
traffic during the parking maneuver.
• Objects situated higher than the detec-
tion area of the sensors are not included
when the parking maneuver is calculated,
which could cause PAP to swing into the
parking space too early. Such parking
spaces should be avoided for this reason.
• PAP 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.
The driver should be aware of the following limi-
tations for Park Assist Pilot:The parking sequence is cancelledA parking sequence will be cancelled if:
• the driver moves the steering wheel
• the vehicle's speed exceeds 7 km/h (4 mph)
• the driver taps
Cancel in the center display
• when the anti-lock brakes or the Electronic
stability control are engaged - e.g. when a
wheel loses grip on a slippery road
• when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").
A message in the center display will explain why
the parking sequence was cancelled.
CAUTION Under certain circumstances, PAP may not be
able to find parking spaces – one reason may
be that the sensors are disrupted by external
sound sources that emit the same ultrasonic
frequencies that the system works with.
Examples of such sources include horns, wet
tires on asphalt, pneumatic brakes, exhaust
noise from motorcycles, etc.

NOTEDirt, ice and snow covering the sensors
reduce their function and can make measure-
ment impossible.
Driver responsibilityThe driver should keep in mind that PAP is a
parking aid ‒ not an infallible fully automatic sys-
tem. The driver must always be prepared to take
control and cancel a parking sequence if neces-
sary.
There are a number of things to keep in mind
when parking, including:
• The driver is always responsible for determin-
ing if the space suggested by PAP is suita-
ble for parking.
• Do not use PAP when using snow chains or
a temporary spare tire.
• Do not use PAP if there are any objects pro-
truding from the vehicle.
• Heavy rain or snowfall may inhibit PAP's abil-
ity to accurately measure a parking space.
• While searching and measuring the parking
space, PAP may be unable to detect objects
located far into the space.
• PAP may not suggest parking spaces on
narrow streets if it does not detect sufficient
space for maneuvering the vehicle. •
Use approved tires 128
inflated to the correct
tire pressure because this affects PAP's abil-
ity to provide parking assistance.
• PAP's function is based on the way the vehi-
cles are parked behind and in front of your
parking space. If they are, for example,
parked too close to the curb, there is a risk
that your vehicle's tires or wheel rims could
be damaged by the curb during the parking
procedure.
• Perpendicular parking spaces may not be
detected or may be suggested unnecessarily
if a parked vehicle is sticking out more than
other parked vehicles.
• PAP is intended to provide parking assis-
tance on straight streets, not sections of
street with sharp curves or bends. Always
make sure that your vehicle is parallel to rel-
evant parking spaces when PAP is measur-
ing the parking space.
CAUTION Switching to another approved wheel and/or
tire dimension could change the tire circum-
ference, which would then require the PAP
system to be updated. Consult a workshop –
an authorized Volvo workshop is recom-
mended.

HYBRID INFORMATION
406General 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
Keep in mind that the vehicle does not emit
any engine noise when using the electric
motor and may therefore be difficult to detect
for children, pedestrians, cyclists or animals.
This is especially true at low speeds, e.g. in
parking lots.
High-voltage electrical current
WARNING Several components in the vehicle work with
high voltage that can be hazardous in case of
an incorrect procedure. 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 some situations, such as in cold weather or if
the hybrid battery's charge level is too low, the
gasoline engine will start instead.
The vehicle should not be started with the charg-
ing cable connected. However, if the cable can-
not be pulled out or if the vehicle incorrectly
detects a cable that is not connected, the vehicle
can be started using an override procedure:
1.

Press the brake pedal and turn the start
knob clockwise.
2. Charge cable Remove before start will
appear in the instrument panel.
3.

Turn the start knob clockwise again.
4. Removed? Turn and hold start knob 7s
will appear. Turn the knob clockwise and hold
it for 7 seconds to start the vehicle. Location of the backup reader in the tunnel console. If the
Vehicle key not found message is shown
in the instrument panel at start, place the remote
key at the backup reader and then make a new
start attempt.
NOTE When the remote key is placed in the backup
reader, make sure that no other vehicle keys,
metal objects or electronic devices (e.g. cellu-
lar phones, tablets, laptops or chargers) are in
the backup reader. Multiple vehicle keys close
to each other in the backup reader can dis-
rupt their functionality.
If Vehicle start System check, wait is dis-
played in the instrument panel while attempting
to start the vehicle, wait until the message disap-
pears and try again to start the vehicle.
CAUTION If the engine has not responded after 3
attempts – wait for 3 minutes before starting
a new attempt. Starting capability increases if
the starter battery is given time to recover.
NOTE
The vehicle cannot be started if the hybrid
battery is discharged.
WARNING •
Always remove the remote key from the
passenger compartment when you leave
the vehicle and make sure the ignition is
in mode 0.
• Always put the gear selector in P and
apply the parking brake before leaving
the vehicle. Never leave the vehicle unsu-
pervised while the engine is running.
• Always open the garage door fully and
make sure that ventilation is very good
before starting the engine in a garage.
The exhaust fumes produced by the vehi-
cle contain carbon monoxide, which is
invisible and odorless but very toxic.
WARNING Never remove the remote control key from
the vehicle while driving.
WARNING
Always take along the remote control key
when leaving the vehicle and make sure that
the vehicle electrical system is in ignition
mode 0 – especially if there are children in
the vehicle.

OFF ROAD
• Maximizes the vehicle's ability to traverse dif-
ficult terrain or poor roads.
In this mode, ground clearance 4
is high, steering
is light, and all-wheel drive and Hill Descent
Control are activated.
This drive mode is only available at low speeds,
up to 40 km/h (25 mph). If this speed is excee-
ded, Off road mode will be cancelled and AWD
mode will be activated instead.
All-wheel drive requires both the combustion and
electric motor to be in continuous operation,
which results in higher fuel consumption.
In Off road mode, a compass will be displayed
between the speedometer and the tachometer in
the instrument panel. The permissible speed
range will be shown in the speedometer.
This drive mode is optimized for maximum control
when driving at low speeds on very poor roads or
difficult terrain. It raises the chassis 4
, reduces
driveline throttle response, and locks the vehicle
in all-wheel drive. The Hill Descent Control func-
tion facilitates controlled driving on steep down-
grades.NOTE This drive mode is not designed to be used
for normal street driving.
NOTE
Due to the increased ground clearance, if the
OFF ROAD mode was selected when the
engine was switched off, the suspension will
lower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when
towing a trailer without an electrical connec-
tion. This could result in damage to the pneu-
matic suspension system's bellows.
AWD
•
Improves the vehicle's traction and handling
by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheel
drive. An optimal distribution between front and
rear axle torque helps provide the best possible
control, stability and traction, e.g. on slippery
roads or when towing a heavy trailer or another
vehicle. The AWD drive mode is always available
regardless of the hybrid battery's charge status. Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
In the other drive modes, the vehicle automati-
cally adapts the need for all-wheel drive accord-
ing to the road surface, and can activate the elec-
tric motor or start the combustion engine as nee-
ded.
POWER
•
Power mode is designed to provide sportier
driving characteristics and a faster accelera-
tion response.
This drive mode maximizes the combined power
from the combustion engine and the electric
motor by providing power to both the front and
rear wheels. Gear shifting will be faster and more
distinct and the transmission will prioritize gears
with a higher traction force. Steering response is
faster, suspension is stiffer and ground clearance
is lower 4
to help reduce body roll when cornering.
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
This drive mode is optimized for maximum per-
formance and throttle response. It changes the
throttle response, gear shifting program and
turbo boost system. Chassis settings and steer-
ing and brake response are also optimized. The
Power drive mode is always available regardless
of the hybrid battery's charge status. 4

The low-speed function, Low Speed Control
(LSC), facilitates and improves control and trac-
tion on rough roads and slippery surfaces, e.g.
when towing a trailer on grass or up boat ramps.
The function is included in the Off Road drive
mode.
Low Speed Control is designed for driving on
rough roads and when towing trailers at low
speeds, up to approximately 40 km/h (25 mph).
When driving at low speeds, LSC prioritizes low
gears and all-wheel drive to help avoid wheel spin
and improve traction on all wheels. The accelera-
tor pedal will be less responsive to improve trac-
tion and speed control at low speeds.
The function is activated together with Hill
Descent Control (HDC), which makes it possible
to control speed going down steep hills using the
accelerator pedal and reduces the need to use
the brake pedal. The system makes it possible to
maintain a low and uniform speed when driving
down steep hills.

Low Speed Control (p. 453)
• Changing drive mode (p. 449) Hill Descent Control
The function for assisting when driving downhill,
Hill Descent Control (HDC), is a low-speed
function with increased engine braking. The
function makes it possible to increase or
decrease the vehicle's speed on steep downhill
gradients by only using the accelerator pedal,
without applying the brakes.
The function is included in the Off Road drive
mode.
HDC is designed for driving on rough roads at
low speeds and downhill gradients with slippery
or otherwise difficult road surfaces. The driver
does not need to use the brake pedal but can
instead focus on steering.
WARNING
HDC is only intended to be a supplementary
braking aid and it does not function in all sit-
uations.
The driver is always ultimately responsible for
operating the vehicle in a safe manner.
FunctionHill Descent Control allows the vehicle to move
forward or backward at very low speeds assisted
by the brake system. The driver can increase the
speed by pressing the accelerator pedal. When
the accelerator pedal is released, the vehicle will
return to very low speed regardless of how steep

the hill is and without the brakes needing to be
applied. The brake lights will illuminate when the
function is activated.
The driver can brake to stop or slow the vehicle
at any time by depressing the brake pedal.
HDC is activated along with Low Speed Control
(LSC), which facilitates and improves traction and
control on rough and slippery surfaces. The sys-
tem is intended to be used at low speeds, up to
approximately 40 km/h (25 mph).
To keep in mind when using HDC
•
If the function is switched off while driving on
a steep downhill gradient, braking effect will
be gradually reduced.
• HDC can be used in gear positions D and R,
and in manual gears 1 or 2.
• It is not possible to manually shift to third
gear or higher when HDC is active.
NOTE When LSC with HDC is activated in the OFF
ROAD drive mode, the feel of the accelerator
pedal and engine response will change.
NOTE
This drive mode is not designed to be used
for normal street driving.
NOTE The function is deactivated when driving at
high speeds and must be reactivated at lower
speeds if so desired.
