Starting And Stopping The Combustion Engine In Twin Engine; Drive Modes - Volvo XC40 Owner's Manual

Starting and stopping the
combustion engine in Twin Engine
An advanced control system determines the
extent to which the car is driven on internal
combustion engine, electric motor or both in
parallel. During electric operation, the car
may sometimes need to start the internal
combustion engine automatically due to
external circumstances, e.g. in low outside
temperatures, which is completely normal. In
addition, the internal combustion engine
always starts when the hybrid battery rea-
ches its lowest state of charge.
Climate settings at low temperatures
In low outside temperatures, the internal com-
bustion engine sometimes starts automatically
in order to achieve the desired passenger
compartment temperature and air quality. The
amount of time that the internal combustion
engine runs can be affected by
lowering the temperature
•
reducing the fan strength
•
activating drive mode Pure
•
Electric operation in low or high
temperatures
In low or high outside temperatures, the car's
range and output for electric operation may be
reduced and affect how often the internal
combustion engine is started automatically.
Emission control
To ensure that emission control operates as
energy-efficiently as possible, the internal
combustion engine must be run for several
minutes once it has been started. The duration
of the internal combustion engine's running
time varies depending on the temperature of
the catalytic converter.

STARTING AND DRIVING

Drive modes

Selection of drive mode affects the car's driv-
ing characteristics in order to enhance the
driving experience and facilitate driving in
special situations.
Using the drive modes it is possible to quickly
have access to the car's numerous functions
and settings for different driving needs. Each
drive mode is adapted to provide optimum
driving characteristics:
Steering
•
Engine/gearbox
•
Brakes
•
Shock absorption
•
Driver display
•
Climate settings
•
Select the drive mode adapted for the current
driving conditions. Remember that not all
drive modes are available in all situations.

WARNING
Remember that the car does not emit any
engine noise when it is only powered by
the electric motor and may therefore be
difficult to notice by children, pedestrians,
cyclists and animals. This applies in partic-
ular at low speeds such as in car parks.
