The rear head restraints are integrated in the roll bar.
The roll bar will be automatically raised in an accident
or in a potentially dangerous driving situation. A ratchet
noise can be heard when the roll bar is automatically
raised.
The roll bar can be lowered again after an automatic
deployment by pressing the upper half of the roll bar
switch (for at least 8 seconds) until the roll bar drive
mechanism audibly engages. Then press the lower half
of the switch to lower the roll bar.
If the roll bar was raised using the switch, it will be
automatically lowered when activating the soft top
switch.
Wa r n i n g !
Raising or lowering of the roll bar could injure rear
seated occupants. Before operating the roll bar switch make sure that
the roll bar’s path is clear and no persons due to
inattention are injured by the moving roll bar. For your own safety we recommend to drive with
the roll bar raised, if
• the outside temperature is below +5
°F (-15
°C).
• the rear seats are occupied by passengers.
Before working on the vehicle, e.g. when changing
wheels, the roll bar should be raised with the
switch, and the electronic key should be removed
from the steering lock, to prevent possible injury. In case of potential danger release the switch to
immediately interrupt the operating procedure.

Switch for roll bar and head restraints, rear
The switch is located in the center console.
Turn electronic key in steering lock to position 2.
Press switch:
1Raise roll bar
2Lower roll bar
The lowering or raising procedure is immediately
interrupted by releasing the roll bar switch. With the engine running and the roll bar lowered, the
warning lamp in the roll bar switch will blink for
approx. 15 seconds. The blinking is reminding you to
raise the roll bar if the rear passenger seats are
occupied. See also page 229 for roll bar warning lamp.
Important!
The roll bar is intended to be a safety enhancement to
the other features designed into the vehicle. No system
in any vehicle can eliminate the possibility of serious
injury or fatality in an accident. Properly fastened seat
belts and child restraints must be used!
Notes:
If the warning lamp in the switch comes on, then a
malfunction has been detected. In this case, drive only
with the roll bar raised until the problem has been
corrected. Raise the roll bar by pressing the upper half
of the roll bar switch.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
Items being transported in the rear passenger
compartment should be placed in such a manner as not
to affect the movement of the roll bar when being
raised.

Notes:
When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.
The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time, or if the battery charge is low. When this occurs,
the indicator lamp in the switch will blink (both
indicator lamps blink during rapid seat heating mode).
The seat heaters will switch on again automatically as
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to
you, the seat heaters can be switched off.Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats,
emergency tensioning devices for the front seat belts,
dual front airbags, door mounted side impact airbags
and knee bolsters for driver and front passenger. Their
protective functions are designed to complement one
another.

Important!
Laws i n mo st states and all Canadi an provi nc es require
seat belt use.
All U.S. states, the District of Columbia, the U.S.
territories and all Canadian provinces require the use of
child restraints that comply with U.S. Fedral Motor
Vehicle Safety Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213 and 210.2.
For your safety and that of your passengers we strongly
recommend their use.
Wa r n i n g !
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
TM compatible child seat,
which operates with the BabySmart
TM system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle's seat belt or lower anchors, fully in
accordance with the child seat manufacturer’s
instructions.A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.
