i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

Restraint system: introduction
The restraint system reduces the risk of vehi-
cle occupants coming into contact with parts of the vehicle's interior in the event of an
accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing systems
The components of the restraint system work
in conjunction with each other. They can only deploy their protective function if, at all times,
all vehicle occupants:
R have fastened their seat belts correctly
(Y page 44)
R have adjusted their seat and head restraint
properly (Y page 89).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 88).
You also have to make sure that an air bag can inflate properly if deployed (Y page 46).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Triggering of the Emer-
gency Tensioning Devices and air bags"
(Y page 54). 40
Occupant safetySafety

Observe the "Important safety notes" section
for driving safety systems (Y page 62).
The Recuperative Brake System converts the kinetic energy when braking into electrical
energy. The electric motor is used as an alter-
nator during braking. This electrical energy is
then stored in the high-voltage battery.
You can find information about manually
adjustable recuperation under "Steering
wheel paddle shifters" (Y page 138).
If the warning light in the instrument cluster is lit up, there is a motor malfunction or a brake
malfunction.
Observe information regarding indicator and
warning lamps (Y page 229) as well as dis-
play messages (Y page 201). Protection against theft
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
X To activate with the SmartKey: remove
the SmartKey from the ignition lock.
X To activate with KEYLESS-GO start-
function or KEYLESS-GO: switch the igni-
tion off and open the driver's door.
X To deactivate: switch on the ignition.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Any-
one can start the drive system if a valid key
has been left inside the vehicle.
i The immobilizer is always deactivated
when you start the drive system.
In the event that the engine cannot be star- ted (yet the vehicle's battery is charged),
the system is not operational. The READY
display in the multifunction display does
not appear. Contact an authorized
Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada). ATA (anti-theft alarm system)

30 seconds, the mbrace emergency call
system automatically notifies the Cus-
tomer Assistance Center. This is done
either by text message or data connection.
The emergency call system sends the mes- sage or data provided that:

vice.
R the mbrace service has been activated
properly.
R the necessary mobile phone network is

WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shift the transmission out of park position P
R start the vehicle's drive system.
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 or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children. G
WARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident. Do not attach any heavy or large objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
! Keep the SmartKey away from strong
magnetic fields. Otherwise, the remote
control function could be affected.
Strong magnetic fields can occur in the
vicinity of powerful electrical installations.
Do not keep the SmartKey: R with electronic devices, e.g. a mobile
phone or another SmartKey.
R with metallic objects, e.g. coins or metal
foil.
R inside metallic objects, e.g. a metal case.
Vehicles with KEYLESS-GO start function: do not keep the SmartKey in the cargo com-
partment. Otherwise, the SmartKey may not
be detected, e.g. when starting the drive sys- tem using the Start/Stop button. SmartKey functions

SmartKeyOpening and closing

The SmartKey centrally locks/unlocks:
R the doors
R the tailgate
R the charge socket flap
The turn signals flash once when unlocking
and three times when locking.
i You can also set an audible signal to con-
firm that the vehicle has been locked. The
audible signal can be activated and deacti- vated using the on-board computer
(Y page 198). KEYLESS-GO
General notes Bear in mind that the engine can be started by
any of the vehicle occupants if there is a
SmartKey in the vehicle.
Locking/unlocking centrally You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the SmartKey with you. You can combine the
functions of KEYLESS-GO with those of a con- ventional SmartKey. Unlock the vehicle by
using KEYLESS-GO, for instance, and lock it
using the &button on the SmartKey.
The driver's door and the door at which the
handle is used, must both be closed. The
SmartKey must be outside the vehicle. When
locking or unlocking with KEYLESS-GO, the
distance between the SmartKey and the cor-
responding door handle must not be greater
than 3 ft (1 m).
A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart- Key is in the vehicle. This occurs, for example:
R when starting the engine
R whilst driving
R when the external door handles are
touched
R during convenience closing X
To unlock the vehicle: touch the inner
surface of the door handle.
X To lock the vehicle: touch sensor sur-
face :or;.
Make sure that you do not touch the inner
surface of the door handle.

closing feature (Y page 84). X
To unlock the tailgate: pull the tailgate
handle.
Deactivating and activating If you do not intend to use the vehicle for a
longer period of time, you can deactivate KEY-
LESS-GO. The SmartKey will then use very lit-
tle power, thereby conserving battery power.
For the purposes of activation/deactivation,
the vehicle must not be nearby. SmartKey
