When The Gasoline Engine Starts And Stops In Hybrid Vehicles; Using The Electric Motor In City Driving - Volvo XC 90 Owner's Manual

STARTING AND DRIVING
When the gasoline engine starts
and stops in hybrid vehicles
An advanced control system determines if your
vehicle is powered by the gasoline engine, the
electric motor or both at the same time. While
the electric motor is being used, the gasoline
engine may start automatically due to external
factors such as low ambient temperatures,
which is normal. In addition, the gasoline engine
will always start when the hybrid battery's charge
level is very low.
Climate system settings for cold
weather
The gasoline engine may start automatically at
low ambient temperatures to help warm the pas-
senger compartment to the desired temperature.
To help minimize the need to use the gasoline
engine:
•
Set a lower passenger compartment tem-
perature
•
Lower the blower speed
•
Pure
Activate the hybrid drive mode
The electric motor in hot or cold
weather
In sustained hot or cold ambient temperatures,
the electric motor's range and capacity may be
reduced, which affects how often the gasoline
engine will start automatically.

Emission controls
In order to help ensure that the gasoline engine's
emission controls function optimally, this engine
will run for several minutes after it has started.
The length of time that the engine needs to run
varies depending on the temperature of the
three-way catalytic converter.

Using the electric motor in city
driving
A number of factors affect the electric motor's
driving range.
The driver can affect some of these factors while
others depend on outside conditions such as
temperature, road surface, etc.
The certified value for the distance that can be
driven on using the electric motor should not be
considered to be an expected distance. The
actual range is affected by a number of factors.
