MERCEDES-BENZ GLE HYBRID 2017 Service Manual

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 †).

Driving using th e engin e
The engin e powers th e vehicle.
The arrows fo r th e energ y flo w are shown in
white.
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 -
vidin g additional drive torque .
The arrows fo r th e energ y flo w are shown in red .
Driving using th e engin e plus energy
recover y
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

Electric operation mode
The electric motor powers the vehicle. The high-
voltage battery supplies energy to the electric
motor.
The arrows for the energy flow are shown in
green.
Electric operation mode and charging the
high-voltage battery
The electric motor is operating as a generator,
e.g. in overrun mode and when braking. The
kinetic energy of the vehicle is converted into
electrical energy. The high-voltage battery is
being charged.
The arrows for the energy flow are shown in
green. Charging the high-voltage battery when

Safety systems The information "while the engine is running" given in the vehicle Operator's Manual regarding the
signaling behavior of a warning/indicator lamp corresponds to the READY driving status. When a
warning/indicator lamp lights up in the READY driving status with the corresponding information,
the causes/consequences and solutions given in the vehicle Operator's Manual also apply to your
vehicle.48
