Deployment of Emergency Tensioning
Devices and air bags
Important safety notes G
WARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified special- ist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of your
passenger to have deployed air bags replaced and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event of a crash. G
WARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera- tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-
sioning Devices which have been triggered
immediately replaced at a qualified specialist workshop.
An electric motor is used by PRE-SAFE ®
to
trigger the tightening of the seat belt in haz-
ardous situations. This procedure is reversi-
ble.
If Emergency Tensioning Devices are trig-
gered or air bags are deployed, you will hear a bang, and a small amount of powder may also be released. The
6restraint system warn-
ing lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released gener-
ally does not constitute a health hazard, but it may cause short-term breathing difficulties in
people with asthma or other respiratory prob-
lems. To avoid this, you may wish to get out of
the vehicle or open the windows as soon as it is safe to do so.
Air bags and pyrotechnic Emergency Tension-
ing Devices (ETDs) contain perchlorate mate-
rial, which may require special handling and
regard for the environment. National guide-
lines must be observed during disposal. In
California, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/
index.cfm .
Method of operation During the first stage of a collision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler-
ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the
Emergency Tensioning Devices during a fron-
tal or rear collision.
An Emergency Tensioning Device can only be triggered, if:
R the ignition is switched on
R the components of the restraint system are
operational; see "Restraint system warning lamp" (Y page 50)
R the belt tongue is engaged in the buckle on
the respective front-passenger seat
The Emergency Tensioning Devices in the
rear compartment are triggered independ-
ently of the lock status of the seat belts. Occupant safety

WARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjected to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There is an increased risk of injury, possibly even
fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the secur-
ing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again.
The securing systems of child restraint sys-
tems are:
R the seat belt system
R the LATCH-type (ISOFIX) securing rings
R the Top Tether anchorages
If it is absolutely necessary to carry a child on the front-passenger seat, be sure to observe
the information on the "Occupant Classifica-
tion System (OCS)" (Y page 59). There you
will also find information on deactivating the
front-passenger front air bag.
All child restraint systems must meet the fol- lowing standards:
R U.S. Federal Motor Vehicle Safety Stand-
ards 213 and 225
R Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found
on an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are inclu-
ded with the child restraint system.
Observe the warning labels in the vehicle inte-
rior and on the child restraint system. Vehicles with seat belt extenders:
when
securing a child in a child restraint system on
a rear seat, observe the following instruc-
tions:
R make sure that the seat belt on the child
restraint system is fastened according to
the manufacturer's installation instruc-
tions for the child restraint system.
R for child restraint systems with a belt
clamp: engage the belt tongue in the buckle
before you tighten the seat belt using the
belt clamp.
Vehicles with a rear reclining seat: when
installing a child restraint system, move the
rear reclining seat backrest to an almost ver-
tical position. The rear reclining seat backrest
must rest against the child restraint system.
Observe the notes on the cushion air bag
(Y page 59).
Vehicles with belt bags: only use a child
restraint system which has been approved by
Mercedes-Benz. Always observe the instruc-
tions and safety notes on belt bags for the
outer seat belts in the rear (Y page 53). LATCH-type (ISOFIX) child seat secur-
ing system G
WARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available. Children in the vehicle

departure
Important safety notes G
WARNING
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.
General notes The "Pre-entry climate control at departure
time" function is only available on PLUG-IN
HYBRID vehicles.
You can use the "Pre-entry climate control at
departure time" function to cool or heat the
vehicle interior if the engine is not running.
The "Pre-entry climate control at departure
time" function can be activated regardless of
whether or not the vehicle is connected to an electric power supply. The condition of
charge of the high-voltage battery must be
higher than the specified minimum condition of charge, however. When the vehicle is connected to an electric
power supply, priority is given to charging the
high-voltage battery to the specified mini-
mum charge. "Pre-entry climate control at
departure time" is only activated subse-
quently.
The running time of the "Pre-entry climate
control at departure time" function may be
reduced if:
R the vehicle is not connected to an electric
power supply and
R the high-voltage battery is not fully charged
With active "Pre-entry climate control at
departure time" the condition of charge of the
high-voltage battery can be reduced, even if
the charge cable connector is connected.
When the vehicle is cooled, the following
functions are activated:
R Climate control system
R Blower
R Seat ventilation 182
Operating the climate control systemsClimate control

The vehicle can be driven by the electric
motor alone up to a speed of approximately
130 km/h.
The vehicle is driven by the electric motor
alone only when all conditions for the auto-
matic engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (Y page 288).
Driving on inter-urban roads
The following phases are possible when driv-
ing on inter-urban roads: R rapid acceleration (boost mode)
R constant energy consumption
R energy recuperation
R electric operation mode
A great deal of recovered energy may be
available, depending on the route profile. This reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption andemissions are favorably influenced in partic-
ular by reduced power losses.
The internal combustion engine will be
switched off automatically, if:
R the driver removes his foot from the accel-
erator pedal in drive program Eand a speed
of 130 km/h is not exceeded
R the driver removes his foot from the accel-
erator pedal in drive program E+and a
speed of 180 km/h is not exceeded.
Further information on the automatic engine
switch-off (Y page 288).
ECO start/stop function General notes
The ECO start/stop function switches the
internal combustion engine off automatically
when the vehicle stops moving and at high
speeds (Y
page 289).
All vehicle systems remain active, e.g. the
automatic climate control. The ECO start/stop function is only available
in drive programs Eand E+. Electric-only
operation is only possible in drive programs E
and E+. Additional information for drive pro-
grams Eand E+(Ypage 285).
Automatic engine switch-off
The engine is switched off automatically,
including when:
