Hybrid drive system Problem
Possible causes/consequences and P Solutions
The hybrid drive system
has been switched off
automatically. You have been in an accident.
The hybrid drive system remains switched off if: R
the internal combustion engine cannot be restarted after a few
seconds. R
the red u restraint system warning lamp in the instrument clus-
ter is lit. X
Consult a qualified specialist workshop.
The hybrid drive system
has been switched off
automatically. The multi-
function display also
shows a display mes-
sage. An electrical short circuit has occurred in the hybrid drive system or an
electrical connection has been disconnected. X
Observe the additional display messages in the multifunction dis-
play (see the vehicle Operator's Manual). X
Consult a qualified specialist workshop.
Driving tips
General driving tips Drive carefully and maintain a safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt braking.
During partial electric driving, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position D and
braking, the electric motor will operate as a gen-
erator.
Further information on the ECO start/stop func-
tion ( Y
page 23).
You can find further driving tips in the vehicle
Operator's Manual.
Stationary vehicle If the vehicle is stopped, the combustion engine
is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tromechanically assisted steering gear allows
you to use the power steering without reduced
comfort. Acceleration Depending on the operating mode, pulling away
and driving under low load conditions are per-
formed: R
entirely by electric propulsion R
in combination with the internal combustion
engine
When accelerating rapidly under increased or
full load, increased boost mode is utilized. The
electric motor supports the combustion engine
by providing additional drive torque.
Overrun mode or braking There are three possible operating modes when
the hybrid vehicle is decelerating: R
energy recovery takes place even when the
vehicle is decelerating purely in overrun mode
( Y
page 20). The electric motor operates as a
generator and stores the recovered energy in
the high-voltage battery R
when the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place ( Y
page 20). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery R
during heavy braking, the service brake is also
used to slow down the vehicle. The two sys-
tems work together26

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.

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

Electric motor performance display
The power display for th e electric motor is loca-

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 .

Driving using th e engin e plus boost mode
If you accelerate th e vehicl e rapidly, th e electric
motor support s th e combustion engin e by pro -

The engin e powers th e vehicle. The electric
motor is operatin g as a generator, e.g. in over-
run mod e and when brakin g ( Y

electrica l energy. The high-voltag e battery is
bein g charged.
