Hybrid drive system
ProblemPossible causes/consequences andMSolutions
The hybrid drive system
has been switched off
automatically.You have been in an accident.
The hybrid drive system remains switched off if:
Rthe internal combustion engine cannot be restarted after a few
seconds.
Rthe red6restraint system warning lamp in the instrument clus-
ter is lit.

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.

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 Dand
braking, the electric motor will operate as a gen- erator.
Further information on the ECO start/stop func-
tion (
Ypage 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:
Rentirely by electric propulsion
Rin 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:
Renergy recovery takes place even when the
vehicle is decelerating purely in overrun mode
(
Ypage 20). The electric motor operates as a
generator and stores the recovered energy in
the high-voltage battery
Rwhen the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place (
Ypage 20). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery
Rduring heavy braking, the service brake is also
used to slow down the vehicle. The two sys-
tems work together

Coolant temperature gauge
GWARNING
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 †).
