Occupant safety
Active head restraints
The active head restraints offer the driver’s
and front passenger increased protection
from whiplash type injuries. In the event of
a rear-end collision, the active head re-
straints on the driver’s and front passen-
ger’s seats are designed to move forward
in the direction of travel, providing the
head with increased support earlier on in
the collision sequence. The active head re-
straints move forward whether the seat is
occupied or not.For information on resetting the activated
active head restraints, see “Resetting acti-
vated head restraints” (
page 401).
You cannot remove the active head
restraint on the driver’s and front passen-
ger’s seat.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Center.
For information on head restraint adjust-
ment, see “Seats” (
page 41).
Warning!
G
Do not attach any objects (e.g. hangers) to
the head restraint posts. Otherwise, the ac-
tive head restraints may not be able to func-
tion properly or offer the intended degree of
protection in the event of a collision.
Warning!
G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of active head restraint. Contact your autho-
rized Mercedes-Benz Center for availability.
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraints so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.

(page 112).
Automatic central locking
The doors and the trunk automatically lock
when the ignition is switched on and the
wheels are turning at vehicle speeds of ap-
proximately 9 mph (15 km / h) or more.
The locking knobs in the doors move down.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.
You can deactivate the automatic locking
mode using the control system
(page 165).
Locking and unlocking from the inside
You can lock or unlock the doors and the
trunk from inside using the central locking
switch. This can be useful, for example, if
you want to lock the vehicle before starting
to drive.
The fuel filler flap cannot be locked or un-
locked with the central locking switch.
i
You can only cancel the separate trunk lock-
ing mode by means of the mechanical key.
i
The doors are designed to unlock automati-
cally after an accident if the force of the impact
exceeds a preset threshold. The vehicle locks au-
tomatically when the ignition is switched on and
the wheels are turning at vehicle speeds of ap-
proximately 9 mph (15 km/h) or more. You could
therefore lock yourself out when the vehicle


is pushed or towed


is on a test stand
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.

Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
!
Excessive coolant temperature triggers the
coolant temperature warning lamp (
page 347)
and a warning in the multifunction display
(
page 374).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C). Doing so
may cause serious engine damage which is not
covered by the Mercedes-Benz Limited Warran-
ty.
i
During severe operating conditions, e.g.
stop-and-go traffic, the coolant temperature may
rise close to 248°F (120°C).
!
Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warran-
ty.
