Battery drain

Your vehicle's electrical functions drain the bat-
tery to varying extents.

Avoid using ignition mode II as much as posssi-
ble, or electrical functions that require a great
deal of electrical current when the engine is not
running.

Using ignition mode I whenever possible con-
sumes less electrical current.

Functions that require a great deal of electrical
current include:

•

the climate system blower

•

headlights

•

wipers

•

infotainment system (especially at high vol-
ume).

If the battery's charge level is low, a text message
will appear in the instrument panel. The vehicle's
energy-saving function will then turn off or
reduce certain functions that are currently con-
suming electrical current.

If the battery needs to be recharged, start the
engine and let it idle for at least 15 minutes or
drive the vehicle (driving charges the battery
faster than letting the engine idle).

Starting the engine

The engine can be started using the start knob
on the tunnel console if there is a remote key in
the passenger compartment.

Start knob in the tunnel console between the front seats

WARNING

Before starting the engine:

•

Fasten the seat belt.

•

Check that the seat, steering wheel and
mirrors are adjusted properly.

•

Make sure the brake pedal can be
depressed completely. Adjust the seat if
necessary.

To start the engine.

1. A remote key must be in the passenger com-

partment. On models with the standard
Passive Start, the key has to be in the front
section of the passenger compartment. If the
vehicle is equipped the optional Passive
Entry system (keyless locking/unlocking) the
key can be anywhere in the vehicle.

2. Press firmly on the brake pedal

3. Turn the start knob toward START and

release it to start the engine.
> The starter motor will crank until the

engine starts or its overheating protection
is triggered.

If the vehicle is moving, it is only necessary to turn the start knob toward START to start the engine.

WARNING

•

Never use more than one floor mat at a
time on the driver's floor. Before driving,
remove the original mat from the driver's
seat floor before using any other type of
floor mat. Any mat used in this position
should be securely and properly anchored
in the attaching pins. An extra mat on the
driver's floor can cause the accelerator
and/or brake pedal to catch. Check that
the movement of these pedals is not
impeded.

•

Volvo's floor mats are specially manufac-
tured for your car. They must be firmly
secured in the clips on the floor so that
they cannot slide and become trapped
under the pedals on the driver's side.

During normal starts, the electric motor is priori-
tized and the gasoline engine will not start. This
means that when the start knob has been turned
toward START and released, the electric motor is
activated ("started") and the vehicle is ready to
be driven. The warning and information symbols
in the instrument panel will go out and the
chosen theme will be displayed to indicate that
the electric motor has been activated.

However, in certain situations, such as in cold
weather or if the hybrid battery is not sufficiently
charged, the gasoline engine will start instead.

NOTE

The vehicle cannot be started if the hybrid
battery is discharged.

Back-up reader in the tunnel console

Vehicle key not found

is displayed in the

instrument panel, place the remote key in the
back-up reader in the tunnel console (see the
illustration) and try again to start the engine.

NOTE

When the remote key is in the back-up
reader, be sure there are no other metallic
objects (e.g., other keys, coins, cell phones) in
the cup holder. This could affect the back-up
reader's function.

Vehicle start

System check, wait

is dis-

played in the instrument panel when you try to

start the vehicle, wait until the message is no
longer displayed and try to start again.

CAUTION

If the engine does not start after the third try,
wait for approximately 3 minutes before trying
to start it again to give the battery time to
recover its starting capacity.

WARNING

•

Always remove the remote key from the
passenger compartment when leaving the
vehicle and ensure that the ignition in
mode 0.

•

On vehicles with the optional Passive
Entry, never remove the remote key from
the vehicle while it is being driven or
towed.

•

Always place the gear selector in Park
and apply the parking brake before leav-
ing the vehicle. Never leave the vehicle
unattended with the engine running.

•

Always open garage doors fully before
starting the engine inside a garage to
ensure adequate ventilation. The exhaust
gases contain carbon monoxide, which is
invisible and odorless but very poisonous.

STARTING AND DRIVING

404

NOTE

After a cold start, idle speed may be noticea-
bly higher than normal for a short period. This
is done to help bring components in the
emission control system to their normal oper-
ating temperature as quickly as possible,
which enables them to control emissions and
help reduce the vehicle's impact on the envi-
ronment.

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. Oil flow may not reach
some lubrication points fast enough to
prevent engine damage.

•

The engine should be idling when you
move the gear selector. Never accelerate
until after you feel the transmission
engage. Accelerating immediately after
selecting a gear will cause harsh engage-
ment and premature transmission wear.

•

Selecting P or N when idling at a stand-
still for prolonged periods of time will help
prevent overheating of the automatic
transmission fluid.

Driving systems

The XC90 T8 Twin Engine Plug-in Hybrid is a
parallel hybrid, which means that it has two sep-
arate drive systems: an electric motor and a gas-
oline engine. Depending on the drive mode
selected and the amount of electric power avail-
able in the hybrid battery, the two systems can
be used in tandem or separately.

Two drive systems

A control system coordinates both of the drive
systems to help optimize driving economy.

Hybrid battery

Gasoline engine

High voltage generator

Electric motor

The gasoline engine and electric motor both gen-
erate power directly to the wheels. The gasoline
engine can also charge the hybrid battery using a

the charging socket and charging will begin
within approx. 10 seconds. The approximate
remaining charging time and charging status
will be displayed in the instrument panel. See
also the article "Hybrid battery charge sta-
tus."

Charging will be temporarily interrupted if the
vehicle is unlocked:

•

If a door is opened, charging will restart
within 2 minutes.

•

if no door is opened, the vehicle will auto-
matically relock and charging will restart
after 1 minute.

NOTE

Charging status is shown in the instrument
panel, which goes dark after a period of time.
Reactivate the instrument panel by:

•

pressing the brake pedal

Charging the hybrid battery

In addition to the conventional fuel tank, the
XC90 T8 Twin Engine Plug-in Hybrid is also
equipped with a rechargeable lithium-ion hybrid
battery.

The hybrid battery is recharged using a charging
cable located in a storage compartment under
the floor of the cargo area. See also the article
"Charging cable."

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 is subjected to flooding, fires, 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.

STARTING AND DRIVING

414

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.

Charging is indicated in three ways:

•

Charge module (the unit that is plugged into
the wall socket): The blue indicator light on
the cable's charge module will flash red sev-
eral times when the unit is plugged into a
wall socket while a safety check is being per-
formed and will then glow steadily blue to
indicate that the charger is ready to use.

•

A green indicator light in the vehicle's charg-
ing socket will flash green while the battery
is charging and will glow steadily green when
the hybrid battery is fully charged. The blue
indicator light in the charge module will also
flash while charging is underway and will
glow steadily blue when charging is comple-
ted.

•

A gauge in the instrument panel will also
indicate the battery's charge level.

The hybrid battery charging process also charges
the vehicle's start battery.

If the hybrid battery's temperature is below –
13

ºF (–10 ºC) or above +104 ºF (+40 ºC), some

of the vehicle's functions may be reduced or not

be available at all (e.g., drive mode may not be
available).

The electric motor cannot be used if the hybrid
battery's temperature is too low or too high. If the
PURE drive mode is selected, the gasoline
engine will be used.

Temperature control

During charging, if the temperature in the charg-
ing cable becomes too high and reaches a critical
limit, charging will be interrupted.

CAUTION

If charging is interrupted repeatedly, have the
charging cable and the vehicle's charging
system inspected by a trained and qualified
Volvo service technician.

Charging using the gasoline engine

Current is generated to charge the hybrid battery, such
as light braking and when engine braking on down-
slopes

Using the B gear mode when driving on down-
slopes will also recharge the hybrid battery.

The hybrid battery can also be charged by the
gasoline engine. During light braking, the battery
is recharged.
