2015 MERCEDES-BENZ GLE SUV charging

Driving on the motorway
When driving on a motorway, 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 Comfortdrive program
and a speed of 130 km/h is not exceeded, the
combustion engine is automatically switched
off.
Further information on the automatic engine
switch-off (Y page 269).
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
130 km/h (Y page 269).
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 internal combustion engine is switched off
automatically if:
R the driver removes his/her foot from the
accelerator in the Comfortdrive program and
a speed of 130 km/h is not exceeded
(Y page 269)
R the internal combustion engine has reached
its operating temperature
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 bonnet 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 charging
(Y page 264).
Automatic engine start
The internal combustion engine, which has been automatically switched-off, starts automatically
in certain situations, when:
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 Sportdrive pro-
gram or to manual gearshifting
R the charge level 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 an alternator and produces the
necessary energy for the auxiliary consumers
and charges the high-voltage battery
Overrun mode is available in the Comfortdrive
program at speeds below 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 route Plug-in hybrid operation

Important safety notes G
WARNING
Operating mobile communications equip-
ment while driving distracts you from paying
attention to traffic conditions. This could also cause you to lose control of the vehicle. There
is a risk of an accident.
Use this device only when the vehicle is sta-
tionary.
You must observe the legal requirements for the country in which you are currently driving when
operating mobile communications equipment in the vehicle.
If it is permitted by law to operate communica-
tions equipment while the vehicle is in motion,
you may only do so if the traffic situation per-
mits. You may otherwise be distracted from the
traffic conditions, cause an accident and injure
yourself and others.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus-
sion surrounding the possible health risk posed
by electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in the
vehicle
R that mutual interference between the vehicle
electronics and mobile phones is minimised
An exterior aerial has the following advantages:
R it conducts the electromagnetic fields gener-
ated by a wireless device to the exterior
R the field strength in the vehicle interior is
lower than in a vehicle that does not have an exterior aerial
Information on retrofitting two-way radios and
mobile phones (RF transmitters) (Y page 433).General notes There are various mobile phone brackets that
may be fitted in your vehicle; in some cases,
these are country-specific.

FeaturesStowing and features

The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Electrostatic
charge is created, for example:
R by wearing synthetic fibre clothing
R by friction between clothing and the seat
R when you pull or push the battery across car-
pet or other synthetic materials
R when you rub the battery with a cloth G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out
of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once. H
Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and disposed of in anenvironmentally responsible
recycling system. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used batter-
ies.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Service
Booklet or contact a qualified specialist work- shop for more information.
! Always have work on the batteries carried
out at a qualified specialist workshop. Should
it, in exceptional circumstances, be abso-
lutely necessary to disconnect the 12-volt
battery yourself, please observe the follow-
ing:
R secure the vehicle to prevent it from rolling
away.
R switch the ignition off.
R first, disconnect the negative terminal, fol-
lowed by the positive terminal.
The transmission is locked in position Pafter
disconnecting the battery.
After the work has been completed, firmly
reinstall the battery and the cover of the pos- itive terminal.

WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion. Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maximum
charging voltage of 14.8 V.
! Only
charge the battery using the jump-start
connection point.
The jump-starting connection point is in the
engine compartment (Y page 397).
X Open the bonnet.
X Connect the battery charger in the same
order as when connecting the donor battery
during jump-starting: to the positive terminal
and earth point (Y page 397).
Keep away from fire and open flames. Do not
lean over the battery. Never charge the battery
if it is still fitted to the vehicle, unless you use a
battery charger which has been tested and
approved by Mercedes-Benz. A battery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. This device
permits charging of the battery in position. Con- tact a Mercedes-Benz Service Centre for infor-
mation and availability. Read the battery charg-
er's operating instructions before charging the
battery.
If the indicator/warning lamps do not light up at
low temperatures, it is very likely that the dis-
charged battery has frozen. In this case you may
neither jump-start the vehicle nor charge the
battery. The service life of a battery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at a qualified specialist workshop.
PLUG-IN HYBRID vehicles: if the battery
charge is sufficient, the high-voltage battery can also supply the 12 V battery. This only happens
if the battery charge of the 12 V battery requires this, e.g. after using electrical consumers for anextended period with the engine switched off.
As the on-board voltage is continuously moni-
tored this can also be performed when the
engine is switched off. The battery charge of the
12 V battery and the on-board voltage are
thereby kept stable for longer. Battery (vehicle)

Charging the high-voltage battery
when stationary (hybrid vehicles)
Only PLUG-IN HYBRID vehicles are equipped
with a high-voltage battery. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
! Only charge the high-voltage battery in the
"Charging when stationary" mode. Do not
connect a battery charger to the high-voltage battery. Otherwise, the vehicle's high-voltage
electrical system could be damaged.
X Stop the vehicle if the internal combustion
engine is running.
The internal combustion engine drives the
electric motor. The electric motor is operating
as an alternator. The high-voltage battery is
charging.
If the high-voltage battery is too heavily dis-
charged, recharge the high-voltage battery to at least 60% of its capacity. In the "Charging when
stationary" operating mode, you can observe
the charge status of the high-voltage battery up to a maximum of 70% in the COMAND display
and in the multifunction display (Y page 264).396
