08 Starting and driving
Drive system - drive modes
Both of the car's drive systems are used
either individually or in parallel. The driver can
select between different drive modes while
driving. Regardless of selected drive mode,
the control system checks that the combina-
tion of drivability, driving experience, environ-
mental impact and fuel economy is always
optimal in relation to the selected drive mode.
If a drive mode cannot be activated then the
reason is explained with a text message in
the combined instrument panel.
NOTE
The drive cannot set the "wrong" drive
mode - if any parameter is not met in a
specific situation, the system will automati-
cally choose another, more appropriate
drive mode.

WARNING
•
Do not leave the car in an unventilated
area with drive mode activated and the
diesel engine switched off - the engine
will start automatically when the
energy level in the hybrid battery is
low, and the exhaust fumes may cause
serious harm to humans and animals.
– PURE
This option focuses on elec-
tric operation as well as low
energy consumption, and
helps the driver to maximise
driving on the hybrid battery.
Since the mileage in electric operation is con-
nected to the car's total energy consumption,
deductions are made for functions that limit
mileage, e.g. climate and dynamic perform-
ance. To obtain the maximum possible mile-
age the air conditioning (p. 124) is therefore
switched off - however, it can be activated
with the AC button if necessary.
NOTE
In the event of misting, press AC, AUTO or
the defroster button.
Please note
This drive mode can only be selected when
the hybrid battery has a sufficiently high
energy level.
The diesel engine can start automatically in
certain cases, despite the PURE drive mode
being selected, for example.:
•
if the speed exceeds 125 km/h
•
if the driver requests more motive force
than electric drive can provide
•
if the hybrid battery's energy level is too
low and it must be charged
•
in the event if system/component limita-
tions, e.g. low outside temperature, see
Energy flow (p. 260).
