2016 MERCEDES-BENZ GLE engine

The volume depends on the engine speed. The
faster you accelerate, the louder the sound is. At
a speed of over 20 mph (30 km/ h) the sound is
switched off. Above this speed, the natural
sounds from the vehicle are sufficient that it can
be heard in good time by other road users.

Starting the engine The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only after
the power demanded by the driver exceeds the
available power that the electric motor can cur-
rently provide.
Noiseless start operation is dependent on the
outside temperature and the operating temper-
ature of the internal combustion engine. If not all
conditions for noiseless start operation are ful-
filled, the vehicle starts with the internal com-
bustion engine.250

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 253).
Additional driving tips ( Y
page 181).
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 242). 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 242). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery. R
when the brakes are applied with greater
force, the service brakes are also used to slow
the vehicle down. The two systems work
together.
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 ( Y
page 253).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads: R
rapid acceleration (boost mode) R
energy recuperation R
electric operation mode
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.252

Driving an d parking

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.
Further information on the automatic engine
switch-off ( Y
page 253).
ECO start/stop function General notes The ECO start/stop function switches the com-
bustion engine off automatically when the vehi-
cle stops moving and at speeds below 80 mph
(130 km/h) ( Y
page 253).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is neither available
in the Sport drive program nor during manual
shifting.
Automatic engine switch-off The engine is switched off automatically, includ-
ing when: R
the driver removes his/her foot from the
accelerator in the Comfort drive program and
a speed of 80 mph (130 km/h) is not excee-
ded ( Y
page 253)R
the engine has reached its operating temper-
ature R
the driver’s seat belt is fastened and the
driver’s door is closed R
the driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance R
the hood is closed and engaged properly R
the high-voltage battery is charged suffi-
ciently R
no malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if: R
the self-diagnosis function of the engine man-
agement is active R
there is a malfunction in the hybrid drive sys-
tem R
the climate control of the vehicle requires it R
the high-voltage battery is being charged
( Y
page 248)
Automatic engine start The automatically switched-off internal combus-
tion engine starts automatically in certain situa-
tions, if: R
the power demand from the driver via the
accelerator pedal is greater than the electric
motor alone can provide R
the driver switches to the Sport drive pro-
gram or to manual gearshifting R
the condition of charge of the high-voltage
battery has reached the lower limit R
the driver has selected the CHARGE operating
mode
Overrun mode In overrun mode, the combustion engine is
switched off and is disconnected from the drive
train. The electric motor: R
generates low thrust, which corresponds to
the overrun mode of an active combustion
engine R
functions as a generator and produces the
necessary energy for the auxiliary consumers
and charges the high-voltage battery
Overrun mode is available in the Comfort drive
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: R
road categories R
speed 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: R
the sections of the journey ahead R
the energy consumption on the whole routePLUG-IN HYBRID operation 253
Driving and parking Z

The condition of charge of the high-voltage bat-
tery is thus systematically controlled. In addi-
tion, the control function takes into account
that: R
the fuel saving through the use of electrical
energy can vary, dependent on the route (e.g.
urban, interurban or highway) R
the 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: R
the Individual drive program is selectedR
in the Individual drive program, the ECO set-
ting is selected under Drive R
HYBRID driving mode is selectedR
active route guidance is activated R
suitable 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.
