Refueling - Mercedes-Benz GLE Hybrid 2019 Operator's Manual

Urban driving
In city traffic, energy is recuperated during fre-
quent deceleration phases.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 80 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off ( page 23).

Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
rapid acceleration (boost mode)
R
recuperation
R
electric operation mode
R
The vehicle can be driven by the electric motor
alone up to a speed of approximately 74 mph
(120 km/h).
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
When driving on a highway, switching off the
combustion engine has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his/her foot from the
accelerator pedal in the Comfort drive program
and a speed of 80 mph (130 km/h) is not excee-
ded, the combustion engine is automatically
switched off.
