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.

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.

Available drive modes
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 particularly true at low speeds, e.g. in
parking lots.
WARNING
Do not leave the vehicle in an unventilated
area with a drive mode activated and the com-
bustion engine switched off. The engine will
start automatically if the charge level in the
hybrid battery is low and the resulting exhaust
gases can be very harmful to people and ani-
mals.
HYBRID
This is the default mode in which the electric
motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control
system uses both the electric motor and the gas-
oline engine - separately or in tandem - and cal-
culates optimal utilization with regard to perform-
ance, fuel consumption and comfort. At high
speeds, ground clearance is automatically low-
ered 3
to reduce air resistance. Driving capacity on
the electric motor alone is determined by factors such as the hybrid battery's charge level, the
need for heat/cooling in the passenger compart-
ment, etc.
If there is sufficient charge in the battery, it is
possible to drive solely on electric power. When
the accelerator pedal is pressed, only the electric
motor will be activated until the battery reaches a
certain charge level. Above this level, the current
in the battery cannot supply the power requested
by the accelerator pedal and the combustion
engine will start.
When the hybrid battery's charge level is low, the
combustion engine will start more frequently to
save the remaining current in the battery. Charge
the hybrid battery from a 120-240 volt outlet
using a charging cable, or activate
Charge in
Function view to reset the option of only using
the electric motor.
This drive mode is designed for low energy con-
sumption with an optimized mix between the
electric motor and gasoline engine, without com-
promising on climate comfort or driving experi-
ence. When faster acceleration is requested by
the driver, the electric driveline will be utilized to
help provide maximum additional power. The
vehicle also monitors the driving conditions and
automatically engages all-wheel drive if neces-
sary. All-wheel drive and extra electric power are
always available regardless of the battery's
charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will
be displayed in the instrument panel. The gauge
will indicate the amount of electrical current
required when the driver depresses the accelera-
tor pedal. The marker between the lightning and
the drop shows how much current is available. The instrument panel gauge when both the electric
motor and the combustion engine are being used.
The instrument panel also shows how
much current is being restored to the
battery (regenerated) during light brak-
ing. 3

Preconditioning
Whenever possible, precondition the vehicle
before driving by connecting the charging
cable to an electrical outlet.
Avoid parking the vehicle somewhere where
the interior will become too hot or too cold
while the vehicle is parked. If possible, park
the vehicle in a climate-controlled garage.
During a short drive after passenger com-
partment preconditioning, turn off the pas-
senger compartment fan or the air condition-
ing in a hot climate.
If preconditioning is not possible when it is
cold outside, use seat and steering wheel
heating first. Avoid heating the entire pas-
senger compartment to reduce the amount
of current being taken from the hybrid bat-
tery.
Driving
Choose the Pure drive mode to help mini-
mize electric power consumption.
Maintain a steady speed and a generous fol-
lowing distance to traffic ahead to minimize
braking. This drive mode has the lowest
power consumption.
Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel to see available electric
power and avoid starting the combustion
engine unnecessarily. The electric motor is more effective than the combustion engine,
especially at low speeds.
When braking is necessary, brake gently
using the brake pedal. This will help recharge
the hybrid battery. A regenerative function is
integrated in the brake pedal and can be
augmented by the electric motor's braking
capacity when the gear selector is in mode
B.
Higher speeds increase energy consumption
- air resistance increases with speed.
Activate the Hold function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
Whenever possible, avoid using the Charge
function to charge the hybrid battery. Charg-
ing the battery using the combustion engine
increases fuel consumption and carbon diox-
ide emissions.
In a cold climate, reduce heating of the wind-
shield/rear window, mirrors, seats and the
steering wheel.
Maintain the correct pressure in the tires and
check pressure regularly.
The type of tires used could affect energy
consumption - consult a retailer for advice on
suitable tires.
Remove unnecessary items from the vehicle
- the heavier the load, the higher the fuel
consumption.
Roof loads increase air resistance and
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upward
gradient by using the accelerator pedal. Use
the brakes instead.

Using the electric motor only
When using the electric motor, Volvo Twin
Engine provides a combination of good fuel
economy, low emissions and high performance.
For energy-efficient driving:
Select the Pure drive mode to help maximize
driving range using only the electric motor.
Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel's hybrid gauge to see avail-
able electric power and avoid starting the
combustion engine unnecessarily.
When braking is necessary, brake gently
using the brake pedal. This will recharge the
hybrid battery.
Activate the
Hold function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
Reduce current consumption in the passen-
ger compartment by reducing e.g. fan speed,
electric heating, or air conditioning use.
Also follow the general economical driving advice
regarding speed, tires and load to maximize
range.

"Hold" and "Charge" functions (p. 471) Factors affecting electric motor
range
A number of factors affect the electric motor's
driving range. The ability to achieve a long driv-
ing range varies according to the outside condi-
tions and to how the vehicle is driven.
The certified value for the distance that can be
driven using the electric motor should not be
considered an expected driving range. The actual
range is dependent on a number of factors.
Factors affecting driving rangeThe driver can influence some factors affecting
driving range, but not all.
The longest range is achieved under very favora-
ble conditions when all factors positively influ-
ence range.

472Preparing for a long trip
It is important to have the vehicle's systems and
equipment checked carefully before driving long
distances.
Check that:
the engine is running properly and that fuel
consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlight
height if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-
rect levels. Change to snow tires when driv-
ing in areas where there is a risk of snowy or
icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

It is important to check the vehicle before driving
in cold/snowy conditions to make sure it can be
driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50%
antifreeze. This mixture helps protect the
engine from frost erosion down to
approx. -35 °C (-31 °F). Do not mix different
types of antifreeze as this could pose a
health risk.
Keep the fuel tank well filled to prevent con-
densation from forming.
Check the viscosity of the engine oil. Oil with
low viscosity (thinner oil) improves cold-
weather starting and reduces fuel consump-
tion when driving with a cold engine.
CAUTION Low-viscosity oil should not be used with hard
driving or in hot weather.
Check the condition and charge level of the
start battery. Cold weather places greater
demands on the start battery and reduces its
capacity.
Use washer fluid containing antifreeze to
help prevent ice from forming in the washer
fluid reservoir.

NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.
Fuel FormulationsDo not use gasoline that contains lead or manga-
nese as a knock inhibitor, and do not use lead
additives. Besides damaging the exhaust emis-
sion control systems on your vehicle, lead has
been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent.
Unburned benzene has been strongly linked to
certain forms of cancer. If you live in an area
where you must fill your own gas tank, take pre-
cautions. These may include:
standing upwind away from the filler nozzle
while refueling
refueling only at gas stations with vapor
recovery systems that fully seal the mouth of
the filler neck during refueling
wearing neoprene gloves while handling a
fuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze during
winter months, do not add solvents, thickeners, or other store-bought additives to your vehicle's
fuel, cooling, or lubricating systems. Overuse may
damage your engine, and some of these additives
contain organically volatile chemicals. Do not
needlessly expose yourself to these chemicals.
WARNING Never carry a cell phone that is switched on
while refueling your vehicle. If the phone rings,
this may cause a spark that could ignite gaso-
line fumes, resulting in fire and injury.
WARNING
Carbon monoxide is a poisonous, colorless,
and odorless gas. It is present in all exhaust
gases. If you ever smell exhaust fumes inside
the vehicle, make sure the passenger com-
partment is ventilated, and immediately return
the vehicle to a trained and qualified Volvo
service technician for correction.
Demanding drivingIn demanding driving conditions, such as when
towing a trailer or driving in hot weather or for
prolonged periods at high altitudes, it may be a
good idea to switch to a higher-octane fuel (AKI
6
91 or higher) or to switch to another brand of
gasoline in order to fully utilize the vehicle's
engine capacity and optimize traction.

WHEELS AND TIRES
* Option/accessory.567
Checking tire pressure
Correct inflation pressure helps improve driving
stability, save fuel and increase the service life of
the tires.
Tire pressure decreases over time, which is nor-
mal. Tire pressure also varies depending on the
ambient temperature. Driving on under-inflated
tires could cause the vehicle to overheat and lead
to damage. Tire pressure affects traveling com-
fort, road noise and driving characteristics.
Check the pressure in the tires every month. Use
the recommended inflation pressure for cold tires
for optimal tire performance and wear. Under-
inflated or over-inflated tires could cause uneven
tread wear.
Use an air pressure gauge and check the infla-
tion pressure on all the tires, including the spare
tire 4
, at least once a month and before long trips.
Volvo strongly recommends buying a reliable air
pressure gauge, as the automatic gauges provi-
ded at service stations may be inaccurate.
WARNING
Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation, or
"blow-out," with unexpected loss of vehi-
cle control and increased risk of injury.
Under-inflated tires reduce the load car-
rying capacity of your vehicle.
Cold tiresInflation pressure should be checked when the
tires are cold.
The tires are considered to be cold when they
have the same temperature as the surrounding
(ambient) air.
This temperature is normally reached after the
vehicle has been parked for at least 3 hours.
After driving for approximately 1.6 km (1 mile),
the tires are considered to be warm. If you need
to drive longer than that to inflate the tires, check
and record the inflation pressure of the tires first
and inflate accordingly when you arrive at the
pump.
When the ambient temperature changes, so does
the inflation pressure. A 10-degree temperature
drop causes a corresponding drop in inflation
pressure of 1 psi (7 kPa). Check the inflation
pressure of the tires regularly and adjust to the correct pressure, which can be found on the vehi-
cle's tire information placard or certification label.
If you check inflation pressure when the tires are
warm, you should never release air. The tires
become warm after driving and it is normal for
warm tires to have an inflation pressure above
the recommended pressure for cold tires. A warm
tire with an inflation pressure equal to or under
the recommended pressure for cold tires could
be significantly under-inflated.Related information

weight
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Weight designationsBefore loading your vehicle, familiarize yourself
with the following terms for determining your
vehicle's weight ratings, with or without a trailer,
from the vehicle's Federal/Canadian Motor Vehi-
cle Safety Standards (FMVSS/CMVSS) label, and
the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of
fuel and all standard equipment. It does not
include passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including
cargo and optional equipment. When towing, tow-
bar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be car-
ried by a single axle (front or rear). These num-
bers are shown on the Federal/Canadian Motor
Vehicle Safety Standards (FMVSS/CMVSS) label.
The total load on each axle must never exceed its
maximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo should never exceed
XXX kg or XXX lbs." on your vehicle's plac-
ard.
2. Determine the combined weight of the driver and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals
1400 lbs. and there will be five 150 lb. pas-
sengers in your vehicle, the amount of availa-
ble cargo and luggage load capacity is 650
lbs. (1400 - 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your
vehicle. Consult this manual to determine
how this reduces the available cargo and lug-
gage load capacity of your vehicle.
