mirror position, push and hold position button “1”, “2” 
or “3” until seat/head restraint and exterior rear view 
mirror movement has stopped. The seat/head restraint 
and exterior rear view mirror movement stops when the 
position button is released.
Caution!
Do not operate the power seats using the memory 
button if the backrest is in an excessively reclined 
position. Doing so could cause damage to front or rear 
seats.
First move the backrest to an upright position.
Synchronizing power seats and head restraints
If the power supply was interrupted (battery 
disconnected or empty), the power seats and head 
restraints are no longer adjusted automatically.
To resynchronize the adjustment feature, turn 
electronic key in steering lock to position 2, move the 
seat completely forward and the head restraint fully 
down, and hold respective buttons for approx. 
2seconds.

Prior to operating the vehicle, the driver should adjust 
the seat height for proper vision as well as fore/aft 
placement and backrest angle to insure adequate 
control, reach, operation, and comfort. The head 
restraint should also be adjusted for proper height. See 
also airbag section on page 61 for proper seat 
positioning.
In addition, also adjust the steering wheel to ensure 
adequate control, reach, operation, and comfort.
Both the inside and outside rear view mirrors should be 
adjusted for adequate rearward vision.
Fasten seat belts. Infants and small children should be 
seated in a properly secured restraint system that 
complies with U.S. Federal Motor Vehicle Safety 
Standards 213 and 225 and Canadian Motor Vehicle 
Safety Standards 213 and 210.2.
All seat, head restraint, steering wheel, and rear view 
mirror adjustments as well as fastening of seat belts 
should be done before the vehicle is put into motion.
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 can 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.

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.
