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)

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

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
