Hybrid vehicles
General notes
Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor.
Important safety notes
Danger of electric shock
GDANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
When towing a vehicle after an accident, be sure
to observe the following sections:
RTransporting the vehicle (Ypage 381)
RTowing a vehicle with both axles on the
ground (Ypage 380)
Read the safety instructions on towing and tow-
starting (
Ypage 379).
All components of the hybrid drive system are
marked with yellow warning stickers that warn
you of the danger of high voltage. The cables of
the vehicle's high-voltage electrical system are
orange in color.
The ignition must be switched off when carrying
out general tasks, such as adding washer fluid to
the windshield washer system or checking the
coolant level.
Automatic switching off of the hybrid
drive system
If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if:
Ran electrical short circuit is detected in the
hybrid drive system
Ran electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact
with high voltage.
Manual switching off of the hybrid drive
system
The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.
!To prevent damage to the hybrid drive sys-
tem please observe the following instruc-
tions:
Ronly deactivate the hybrid drive system
manually in the following situations.
Rwork on the hybrid drive system may only
be carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.

Safety

If the hazardous situation passes without result-
ing in an accident, the original settings are
restored.
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe electrically adjustable steering wheel is
raised
Rthe engine is switched off and the fuel supply
is cut off
Rvehicles with seat belt extenders: the seat-
belt buckles for the outer rear seats are illu-
minated and extend forwards
Rvehicles with mbrace: automatic emergency
call
Rvehicles with the hybrid drive system: the
hybrid system and the high-voltage electrical
system are deactivated
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children
are generally better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child
Rbe sure to observe the instructions and safety
notes in this section in addition to the child restraint system manufacturer's installation
instructions
Rbe sure to observe the instructions and safety
notes on the "Occupant classification system
(OCS)" (
Ypage 53)
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The air filter
cleans the air, thus improving the interior cli-
mate.
For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
only available when the engine is running. For
hybrid vehicles, the "Cooling with air dehumidi-
fication" function is also available via the elec-
tric refrigerant compressor when the engine is
not running. Optimum climate control is only
achieved with the side windows and roof closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 164).
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 152).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 95). This will speed
up the cooling process and the desired inte- rior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book- let.
iIt is possible that the blower may be activa-
ted automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly. For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
available when the engine is running. For hybrid
vehicles, the "Cooling with air dehumidification"
function is also available via the electric refrig-
erant compressor when the engine is not run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
