230 Parking climate
The passenger compartment climate can be pre-
conditioned or maintained when the vehicle is
parked. For full functionality, the vehicle's charg-
ing cable must be plugged in. Preconditioning and the climate comfort retaining func-
tion are controlled from the Parking climate tab in the
center display's Climate view.

(p. 236) Preconditioning
Preconditioning the vehicle before driving can
help reduce wear and reduce energy consump-
tion during a trip.
Preconditioning can be started immediately or
started at a preset time using a timer.
The function utilizes several of the vehicle's sys-
tems:
• In cold weather, the high-voltage coolant
heater (HVCH) heats the passenger com-
partment to a comfortable temperature.
• In warm weather, air conditioning cools the
passenger compartment to a comfortable
temperature.
• The electrically heated steering wheel* and
seats* can be activated.
• Heating for the windshield, rear window and
door mirrors are automatically activated as
needed.
During preconditioning in a hot climate, conden-
sation from the air conditions may drip under the
vehicle. This is normal.

NOTE Preconditioning is only available when the car
is connected to an electrical outlet. A charg-
ing post that is not always active, for example
because of a timer, can cause loss of function
for preconditioning.
If the car is not connected to an electrical
socket it is still possible in a warm climate to
achieve brief cooling of the passenger com-
partment by direct starting preconditioning.
NOTE
During preconditioning of the passenger
compartment, the vehicle works to reach a
comfortable temperature and not the tem-
perature set in the climate system.

||DRIVER SUPPORT
* Option/accessory.
324 The driver is responsible for ensuring that
the vehicle maintains a suitable distance
from such obstacles.
• The camera and radar sensors do not
have the capacity to detect all oncoming
objects and obstacles in traffic environ-
ments, e.g. potholes, stationary obstacles
or objects that completely or partially
block the route.
• Pilot Assist does not "see" pedestrians,
animals, etc.
• The recommended steering input is lim-
ited in force, which means that it cannot
always help the driver to steer and keep
the vehicle within the lane.
• Pilot Assist is switched off if the power
steering is working with reduced power -
e.g. during cooling due to overheating
(see section "Speed-dependent steering
force").
The driver can always correct or adjust steering
assistance provided by Pilot Assist by turning the
steering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be driven on
flat roads. The function may not be able to main-
tain the correct time interval to the vehicle ahead
when driving down steep hills. The driver should be extra attentive and prepared to apply the
brakes.
• Do not use Pilot Assist if the vehicle is carry-
ing a heavy load or towing a trailer.
NOTE Pilot Assist cannot be activated if a trailer,
bike carrier or similar is connected to the
vehicle electrical system.
Other limitations
•
The
Off Road drive mode cannot be
selected when Pilot Assist is activated.
NOTE The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".

HYBRID INFORMATION
}}
407
Charging the hybrid battery
In addition to the conventional fuel tank, your
vehicle is also equipped with a rechargeable
lithium-ion hybrid battery.
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 Volvo retailer or author-
ized Volvo workshop.
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 hybrid battery's charging process also
charges the vehicle's start battery.
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
