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.

Disconnect the charger from the wall out-
let before cleaning it.
• Never connect the charging cable to an
extension cord or a multiple plug socket.
Also, refer to the manufacturer's instructions
for using the charging cable and its compo-
nents.
CAUTION Make sure that the 120/240 V outlet (AC,
alternating current) has a power capacity suf-
ficient for charging electric vehicles. If you are
uncertain of the capacity, have the outlet
checked by a licensed electrician.
Take out the charging cable from the storage
compartment under the cargo area. Note that the
ignition must be switched off completely before
charging. Plug the charging cable into a 120/240 V
outlet. Never use an extension cord.
Open the charger door and remove the
charging socket's protective cover. Push the
charging handle all the way into the vehicle's
socket.3.

The charging cable handle will lock into
place and charging will begin within
5 seconds. When charging starts, the green
LED light in the charging socket will begin to
flash. The approximate remaining charging
time or the charging status will be displayed
in the instrument panel.
Charging may be temporarily interrupted if
the vehicle is unlocked:
• and a door is open ‒ charging will restart
within a few minutes.
• if no door is opened ‒ the vehicle will
automatically relock. Charging will resume
after 1 minute.
CAUTION Never detach the charging cable from the
120/240 V outlet (AC, alternating current)
while charging is in progress – the
120/240 V outlet could be damaged in such
circumstances. Always interrupt charging first
and then disconnect the charging cable – first
from the vehicle's charging socket and then
from the 120/240 V outlet.
During charging, condensation from the air con-
ditioning may form under the vehicle. This is nor-
mal and is caused by the hybrid battery cooling.

424 Starting the vehicle
The vehicle can be started using the start knob
in the tunnel console when the remote key is in
the passenger compartment. Start knob in the tunnel console.
WARNING
Before starting:
• Buckle your seat belt.
• Adjust the seat, steering wheel and mir-
rors.
• Make sure you can fully depress the
brake pedal. The remote key is not physically used to start the
ignition because the vehicle is equipped with the
keyless Passive Start system.
To start the vehicle:
1.

The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must
be in the front section of the passenger
compartment. With the optional keyless lock-
ing/unlocking function*, the key can be any-
where in the vehicle.
2. Press and hold down the brake pedal 1
as far
as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the
original position.
WARNING •
Never use more than one inlay mat at a
time on the driver's floor. If any other type
of floor mat is used, remove the original
mat from the driver's seat floor before
driving. All types of mats must be securely
anchored in the attachment points in the
floor. Make sure the floor mat does not
impede the movement of the brake pedal
or accelerator pedal in any way, as this
could be a serious safety hazard.
• Volvo's floor mats are specially manufac-
tured for your vehicle. They must be prop-
erly secured in the attachment points in
the floor to help ensure they cannot slide
and become trapped under the pedals.
The starter motor will crank until the engine
starts or until its overheating protection is trig-
gered.
During normal start conditions, the vehicle's elec-
tric motor will be prioritized and the gasoline
engine will remain off. This means that once the
start knob is turned clockwise, the electric motor
has been "started" and the vehicle is ready to be
driven. The warning and information symbols in
the instrument panel will go out and the selected
theme will be displayed to indicate that the elec-
tric motor is activated. 1
If the vehicle is moving, it is only necessary to turn the start knob cl\
ockwise to start the engine.

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.

||STARTING AND DRIVING
426
NOTE
With a cold start, idling speed may be consid-
erably higher than normal for certain engine
types. This is done to get the emissions sys-
tem up to normal operating temperature as
quickly as possible, which minimizes exhaust
emissions and protects the environment.
CAUTION
•
When starting in cold weather, the auto-
matic transmission may shift up at slightly
higher engine speeds than normal until
the automatic transmission fluid reaches
normal operating temperature.
• Do not race a cold engine immediately
after starting. This could prevent fluids
from properly lubricating vital compo-
nents in the engine before it has reached
the proper operating temperature.
• The engine should be idling when the
gear selector is moved. Never accelerate
until the gear is fully engaged. Accelerat-
ing rapidly before a gear is properly
engaged could lead to harder wear of
components.
• To help prevent the transmission oil from
overheating, select P or N when idling at
a standstill for prolonged periods of time.

Gear selector positions for
automatic transmissions
In vehicles with an automatic transmission, the
system selects the optimal gear for the current
driving conditions. The transmission also has a
manual mode.
The instrument panel shows which gear is cur-
rently in use:
P
, R, N, D or B.
For manual shifting, the gear indicator in the
instrument panel displays the gear currently
being used (1-8).
Selecting gearsThe gear selector is a shift-by-wire selector,
where shifting is done electronically instead of
mechanically. This makes shifting easier and the
gear positions more distinct. Select gears by moving the spring-loaded, non-
locking gear selector forward or backward.
Gear selector positions
Park - P
Park is activated using the P button located next
to the gear selector. Select P when the vehicle is parked or when star-
ting the engine. The vehicle must be stationary
when Park is selected.
To move to another gear from Park, the brake
pedal must be depressed and the ignition in
mode II.
When parking – apply the parking brake before
shifting to Park.
WARNING Always apply the parking brake when parking
on an incline. Selecting a gear or putting the
automatic transmission in P may not be suffi-
cient to keep the vehicle stationary in all sit-
uations.
NOTE The gear selector must be in the P position
before the vehicle can be locked and the
alarm set.
