STARTING AND DRIVING
}}
455
Factors the driver can influence
The driver should be aware that the following fac-
tors affect the range so he/she can operate the
car in an energy-efficient manner:
•
regular charging
•
preconditioning
•
drive mode Pure
•
climate settings
•
speed and acceleration
•
Hold
function
•
tyres and tyre pressure.
The table below shows the approximate relation-
ship between constant speed and range, where a
lower constant speed has a positive effect on
range.
Constant speed
100 km/h (62 mph) 50 %
80 km/h (50 mph) 70 %
60 km/h (37 mph) 90 %
50 km/h (31 mph) 100 %
NOTE
•
The values shown in the tables relate to a
new car.
•
These are not absolute values, but are
dependent upon driving behaviour, envi-
ronment and other circumstances.

"Hold" and "Charge" function
In some situations, it can be useful to be able to
control the hybrid battery's state of charge while
driving is in progress. This is possible using the
Hold
and
Charge
functions which are available
in all drive modes.
Function buttons for Hold and Charge
The functions are activated in the centre display's
function view.
Hold
Battery level sustained for
later use
.
The function maintains the
charge in the hybrid battery for
electric operation saves availa-
ble electrical energy for later
use, e.g. for driving in an urban environment or
through a residential area.
Hold is available
regardless of the hybrid battery's state of charge.
The car works as for normal hybrid operation with
discharged battery where, in addition to re-using
brake-generated energy, for example, the car
starts the internal combustion engine more often
in order to maintain the charge in the battery.
