STARTING AND DRIVING
* Option/accessory. 471
Energy distribution in hybrid drive
using map data
*
The
Hybrid
drive mode is the car's normal mode
where the electric motor and internal combus-
tion engine work individually or together in hybrid
drive. If a destination has been selected in the
navigation system
* , the Predictive Efficiency
10
function distributes the electric energy consump-
tion in an intelligent way along the whole driving
distance using the map data.
Fuel consumption can then be reduced com-
pared with normal hybrid drive when the car is
first driven on electricity, to then change over to
being driven by the internal combustion engine
when the hybrid battery has been discharged.
Function
If the distance to the selected destination is
greater than the estimated range when running
on electricity, this function distributes the electric
energy to optimise consumption for the entire
distance to be travelled. This makes it possible to
avoid situations where normal hybrid drive would
otherwise use a large proportion of the electric
energy, for example, to run electric drive at high
speed on a motorway and then use the internal
combustion engine at low speed in urban driving.
The greatest fuel saving is achieved when
•
the distance to be travelled begins with driv-
ing on a motorway
•
the distance to be travelled is between 50
and 100 km (30 and 60 miles)
•
the hybrid battery is fully charged at the
beginning.
Conditions for the function
For the function to work requires that a number
of conditions are met:
•
A destination is set in the navigation system
and the driving distance to the destination is
longer than the range possible only on elec-
tric drive.
•
Hybrid drive mode is selected.
•
The Hold and Charge functions are deacti-
vated.
•
The hybrid battery is charged.
Tips for use
If the car is used for commuting to work and it is
not possible to charge the car at the place of
work, specify the place of work as an intermedi-
ate destination and your home as the final desti-
nation. The discharging of the hybrid battery will
then take place over your runs both to and from
work.
Add similar commuting routes, i.e. the route
between two charging points, as
Favourites in
the navigation system to facilitate arrival.
