left connected to the power socket, the cur-
rently selected values will be used for the next
charging process. R
removed from the power socket, the values
will be reset to the minimum setting for the
next charging process. You may then need to
reset the values of the maximum charge cur-
rent.

Important safety notes
G WARNIN G
If you operate information systems and com-
munication equipmen t integrate d in th e vehi-
cle while driving , you will be distracte d from
traffic conditions. You could also lose control
of th e vehicle. Ther e is a ris k of an accident.
Only operate th e equipmen t when th e traffic
situation permits. If you are no t sur e that this
is possible , park th e vehicl e payin g attention
to traffic condition s and operate th e equip-
men t when th e vehicl e is stationary.
You must observ e th e legal requirements for th e
country in whic h you are currentl y driving when
operating th e on-board computer.
G WARNIN G
If th e instrumen t cluste r has faile d or mal-
functioned, you may no t recognize function
restriction s in systems relevan t to safety. The
operating safet y of your vehicl e may be
impaired . Ther e is a ris k of an accident.
Pull ove r as soo n as it is saf e to do so and
consult a qualified specialist workshop.
The on-board computer only shows message s or
warning s from certain systems in th e multifunc-
tion display. You should therefor e mak e sur e
your vehicl e is operating safely at all times .

tration ( Y

cluster. R
Area C to D (E-DRIVE):
This shows th e electric output from th e elec -
tric motor, e.g. during electric operation or in
boos t mode.
When th e motor is switched on , th e needle is
at limi t C . Wit h increasing pressur e on th e
accelerato r pedal th e needle moves from C
to D .
Driving with th e electri c motor: when th e
needle reaches limi t D th e combustion
engin e is switched on . If th e display
approaches limi t D and you remove your foo t
from th e accelerato r pedal , th e needle drops
again . The combustion engin e is no t switched
on . At low speeds, you can thereby control th e
electric operation usage so that you only driv e
in electric mode.
Driving with th e combustion engine: th e
electric motor support s th e combustion
engin e by providing additional driv e torque
(boost mode) until th e needle reaches
limi t D .

Coolant temperature gauge
G WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
! A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The engine
will otherwise be damaged.
The multifunction display shows the coolant
temperature in the Coolant submenu.
Under normal operating conditions and with the
specified coolant level, the coolant temperature
may rise to 248 ‡ (120 †).
