ing light through the charging cable. Charging is in progress and the approximate time at which the
battery will be fully charged is displayed.Charging complete is displayed. An image will be superimposed over
the graphic of the vehicle with a green LED indicator light in the socket. The battery is fully charged.Charging error will be displayed. The LED indicator light in the charg-
ing socket will be red. Malfunction. Make sure the charging cable is correctly con-
nected to the vehicle's charging socket and to the 120/240 V

NOTE
If the instrument panel is not used, it will go
dark after a period of time. To reactivate the
display:

depress the brake pedal,
open one of the doors, or

Stopping hybrid battery charging
To stop charging of the hybrid battery, unlock
the vehicle, unplug the charging cable from the
vehicle's charging socket and then unplug the
cable from the 120/240 V outlet (alternating
current).
CAUTION Before the charging cable is removed from
the vehicle's charging socket, the vehicle
must be unlocked using the unlock button on
the remote key. This must be done even if the
vehicle's doors are already unlocked. If the
vehicle is not unlocked using the unlock but-
ton, the charging cable or system may be
damaged.
NOTE
Always unlock the vehicle so that charging is
cut off before the connection to the
120/240 V outlet (AC, alternating current) is
disconnected. Note that the charging cable
must be disconnected from the vehicle's
charging socket before it is disconnected
from the 120/240 V outlet, partly to prevent
damage to the system and party to prevent
unintentional interruption of charging. Unlock the vehicle with the remote key.
Charging will stop.
Press the lock button on the charging
cable's handle. The handle will be released/
unlocked. Remove the cable from the vehi-
cle's charging socket, put the socket's cover
back in place and close the charger door. Unplug the cable from the 120/240 V outlet.
Stow the charging cable in the storage com-
partment under the cargo area floor.
Charging cable automatically locksIf the charging cable cannot be removed from the
charging socket, it will automatically lock into
place again after unlocking to maximize charging
and range and to enable preconditioning before
driving. The charging cable can be removed again
if the vehicle is unlocked using the remote key.
For vehicles with Passive Entry*, the handle can
be used to lock and unlock.

HYBRID INFORMATION
432Long-term storage of vehicles with
hybrid batteries
To help minimize degradation of the hybrid bat-
tery if the vehicle is not driven for a prolonged
period (longer than 1 month) the hybrid battery
charge level should be kept at approx. 25%
according to the gauge in the instrument panel.
Do as follows:
1. If the hybrid battery charge level is high, drive
the vehicle until the charge level is approxi-
mately 25%. If the charge level is low, charge
the battery until the level reaches approxi-
mately 25%. 2.

If the vehicle is not driven for more than 6
months or the hybrid battery's charge level is
noticeably below the 25% mark, charge the
battery to about 25% to help compensate for
the natural battery discharge that occurs in
long-term storage. Regularly check the
charge level using the gauge in the instru-
ment display.
NOTE Store the vehicle in as cool a location as pos-
sible to minimize battery aging during long-
term storage. In the summer, park the vehicle
indoors or in a shady location, whichever is
cooler.

STARTING AND DRIVING
453
Drive systems
Volvo Twin Engine combines a combustion
engine for the front wheels and an electric motor
for the rear wheels.
Two drive systemsDepending on the selected drive mode and
power available in the electric motor, the drive
systems can either be used separately or in tan-
dem.
The electric motor gets its energy from a hybrid
battery located under the tunnel console. The
hybrid can be charged from a wall outlet or in a
special charging station. The combustion engine
can also charge the hybrid battery using a special
high-voltage generator.
Both the combustion engine and the electric
motor can generate power directly to the wheels.
An advanced control system coordinates both the
drive systems to help optimize driving economy. Hybrid battery - The hybrid battery's function
is to store electrical current. This energy is
provided by plugging the charging cable into
an electrical outlet, through regenerative
braking or from the high-voltage generator.
This provides current to power the electric
motor and to temporarily power the electrical
air conditioning to precondition the passen-
ger compartment.
Combustion engine - The combustion engine
starts when the charge level in the hybrid
battery is too low to provide the power output
requested by the driver.
High-voltage generator
2
- Charges the hybrid
battery. Starter for the combustion engine. Can provide the combustion engine with
extra electrical current. Electric motor - Powers the vehicle using
electricity. Can provide extra torque and
power during acceleration. Provides electrical
all-wheel drive functionality. Regenerates
braking energy into electrical current.
