Charging cable handle and charging socket.
Charging status is indicated in three ways:
The indicator lights in the charging module
(the unit connected to the wall outlet).
Indicator light in the vehicle's charging
socket.
Images and text in the instrument panel.
The start battery is charged while the hybrid bat-
tery is charging and stops charging when the
hybrid battery is fully charged.
If the hybrid battery's temperature is below
-10 ºC (14 ºF) or above 40 ºC (104 ºF), some of
the vehicle's functions may be reduced or not
available at all.
The electric motor cannot be used if the battery's
temperature is too low or too high. If the PURE
drive mode is selected, the gasoline engine will
start.
Charging using the gasoline engine The vehicle generates electrical current to charge the
battery, e.g. when the driver lightly presses the brake
pedal or when engine braking is used on downgrades.
The vehicle can also generate current to the
hybrid battery to charge it.
The hybrid battery can also be recharged by
lightly depressing the brake pedal, i.e. during
light braking. This converts the vehicle's
kinetic energy to electrical energy, which is
used to charge the hybrid battery.
In gear position B, the electric motor brakes
the vehicle when the accelerator pedal is
released and the hybrid battery is recharged
at the same time.
The combustion engine can also help
recharge the hybrid battery.Related information

Charging current
Charging current is used to charge the hybrid
battery and precondition the vehicle. Charging is
performed by connecting a charging cable
between the vehicle's charging socket and a
120/240 V electrical socket (alternating cur-
rent).
When the charging cable is activated, a message
will be displayed in the instrument panel and an
indicator light in the vehicle's charging socket will
illuminate. Charging current is primarily used for
battery charging, but is also used for precondi-
tioning. The vehicle's start battery is charged
along with the hybrid battery.
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.
NOTE
In extremely cold or hot weather, part of
the charging current is used to heat/cool
the hybrid battery and the passenger
compartment, resulting in a longer charg-
ing time.
The charging time is longer if precondi-
tioning has been selected. The time
required depends primarily on the ambi-
ent temperature.
FuseThere are normally several 120/240 V power
consumers in one fuse circuit, which means that
more than one power consumer (e.g. lighting,
vacuum cleaner, electric drill, etc.) may use the
same fuse.

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.

Charging status in the vehicle's
charging socket
The charging status is indicated by an LED light
in the charging socket. Location of the LED indicator light in the vehicle's
charging socket.
The LED indicator light shows the current charge
status during charging. If the LED indicator light
is not illuminated, check to make sure the cable
is securely connected in the wall outlet and in the
outlet in the vehicle. A white, red or yellow light
illuminates when the passenger compartment
lighting is activated and will remain illuminated for
a short time after the passenger compartment
lighting has gone out. LED indicator

indicate the status of ongoing and completed
charging. Charge module: 1. Red warning light, 2. Blue status indi-
cator
When the charge module is initially plugged into
a wall outlet, the red warning light will flash once
to indicate that a startup safety check has been
performed. When the safety check has been
completed, the blue status indicator will glow
steadily and the red warning light will be off. The
charger is now ready to be used. If the red warn-
ing light continues to flash or glows steadily, a
fault has been detected and the charger will not
deliver power to the vehicle. Contact a Volvo
retailer or a certified Volvo service technician.

STARTING AND DRIVING

Brake Assist System
The brake enhancing system, Brake Assist
System (BAS

), helps increase braking force and
thereby reduce braking distance.
The system monitors the driver's braking habits
and increases braking force when necessary.
Braking force can be increased up to the point at
which the ABS intervenes. The function is deacti-
vated when pressure on the brake pedal is
decreased.
Related information
Brakes (p. 439) Braking on wet roads
Prolonged driving in heavy rain without braking
may cause braking effect to be slightly delayed
the first time the brakes are applied.
This may also occur after washing the vehicle. It
will then be necessary to apply greater pressure
to the brake pedal. You should therefore maintain
a greater distance to the vehicle ahead.
Firmly apply the brakes after washing the vehicle
or driving on wet roads. This helps warm up the
brake discs, enabling them to dry more quickly
and protecting them against corrosion. Consider
the current traffic situation when braking.

Brakes (p. 439)
Braking on salted roads (p. 441) Braking on salted roads
When driving on salted roads, a layer of salt may
form on the brake discs and brake pads.
This could increase stopping distance. Maintain
an extra large safety distance to the vehicle
ahead. Make sure to also:
Apply the brakes from time to time to help
remove salt. Make sure braking does not
pose a risk to any other road users.
Gently apply the brakes when you have fin-
ished driving and before driving again.

STARTING AND DRIVING
442Maintenance of the brake system
Regularly check the brake system components
for wear.
To keep the vehicle as safe and reliable as possi-
ble, follow the Volvo service schedule specified in
the Warranty and Maintenance Records Informa-
tion booklet. New and replaced brake pads and
brake discs do not provide optimal braking effect
until they are "broken in" by driving a few hun-
dred kilometers (miles). Compensate for the
reduced braking effect by applying greater pres-
sure to the brake pedal. Volvo recommends only
using brake pads approved for your Volvo.
CAUTION The brake system's components should be
regularly checked for wear.
Contact a workshop for advice on how to do
this or let a workshop perform the inspection
- an authorized Volvo workshop is recom-
mended.

Brakes (p. 439) Parking brake
The parking brake helps keep the vehicle sta-
tionary by mechanically locking two wheels.
The parking brake controls are located in the tunnel
console between the seats.
When the electric parking brake is being applied,
a faint sound can be heard from the brake's elec-
tric motor. This sound can also be heard during
the automatic function check of the parking
brake.
If the vehicle is stationary when the parking brake
is applied, it will only be applied to the rear
wheels. If it is applied while the vehicle is moving,
the normal brakes will be used on all four wheels.
Braking will be transferred to only the rear
wheels when the vehicle is almost stopped.
