auxiliary battery MERCEDES-BENZ GLE SUV HYBRID 2017 W166 Owner's Manual

Overrun mode
In overrun mode, the combustion engine is
switched off and is disconnected from the drive
train. The electric motor:
Rgenerates low thrust, which corresponds to
the overrun mode of an active combustion
engine
Rfunctions as a generator and produces the
necessary energy for the auxiliary consumersand charges the high-voltage battery
Overrun mode is available in the Comfortdrive
program at speeds below 80 mph (130 km/h).
Route-based operating strategy
For the route-based operating strategy, the sys-
tem factors in information about the expected
route when route guidance is active.
The information on the route is provided by the
multimedia system and includes the following:
Rroad categories
Rspeed limitations
The use of electric energy is automatically opti-
mally distributed from the beginning to the end
of the journey, using information about the
route. The distribution is pre-emptive and takes
into consideration:
Rthe sections of the journey ahead
Rthe energy consumption on the whole route The condition of charge of the high-voltage bat-
tery is thus systematically controlled. In addi-
tion, the control function takes into account
that:
Rthe fuel saving through the use of electrical
energy can vary, dependent on the route (e.g.
urban, interurban or highway)
Rthe use of electrical energy is held available
for electric driving, particularly for urban
routes
The vehicle thus automatically selects the opti-
mum driving mode for the respective section of
the route.
The route-based operating strategy is available
under the following conditions:
Rthe Individual drive program is selected
Rin theIndividual drive program, the ECO set-
ting is selected under Drive
RHYBRID driving mode is selected
Ractive route guidance is activated
Rsuitable map data is available
When the route-based operating strategy is
being used, the area in front of the vehicle is
shown as green in the multifunction display.

The battery is being charged. When the condition of charge of the
high-voltage battery is over the specified minimum, pre-entry cli-
mate control is operational again.
Warning and indicator lamps in the instrument cluster
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.
