Automatic central locking
The central locking switch also operates the automatic
central locking.
With the automatic central locking system activated, the
doors and trunk are locked at vehicle speeds of approx.
9 mph (15 km/h) or more. The fuel filler flap remains
unlocked.
To a c ti va te :
With electronic key in steering lock position 2 hold
upper portion of switch (1) for a minimum of 5 seconds.
To d ea ct iva te:
With electronic key in steering lock position 2 hold
lower portion of switch (2) for a minimum of 5 seconds.
Notes:
If doors are unlocked with the central locking switch
after activating the automatic central locking, and
neither door is opened, then the doors remain unlocked
even at vehicle speeds of approx. 9 mph (15 km/h) or
more.If a door is opened from the inside at speeds of approx.
9 mph (15 km/h) or less with the automatic central
locking activated, the door will again be automatically
locked at speeds of approx. 9 mph (15 km/h) or more.
Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:
With the automatic central locking activated and the
electronic key in steering lock position 2, the vehicle
doors will lock if the left front wheel as well as the right
rear wheel spin at vehicle speeds of approx. 9 mph
(15 km/h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking.
Emergency unlocking in case of accident
The doors unlock automatically a short time after a
strong deceleration is detected, such as in a collision
(this is intended to aid rescue and exit).
Driving on rough roads may cause the vehicle to unlock.
If necessary, the vehicle can be locked again with the
central locking switch, see page 33.

The slide switches are located in each door.
We recommend to adjust the power seat in the following
order:
1Seat, up/down
Press the switch (up/down direction) until
comfortable seating position with still sufficient
headroom is reached.
2Seat, fore/aft
Press the switch (fore/aft direction) until a
comfortable seating position is reached that still
allows you to reach the accelerator/brake pedal safely. The position should be as far rearward as
possible, consistent with ability to properly operate
controls.
Note:
Do not move the front passenger seat completely
forward if objects are stored in the parcel net in the
front passenger side footwell. Items in the net may
be damaged.
3Seat cushion tilt
Press the switch in the direction of the arrow until
your legs are lightly supported.
4Backrest tilt
Press the switch in the direction of the arrow until
your arms are slightly angled when holding the
steering wheel.
5Head restraint
During seat adjustment, the head restraint is
automatically adjusted based on seat (fore/aft)
position to support the back of the head
approximately at ear level. Please check the position
of the head restraint to assure that it supports the
back of the head approximately at ear level. The
head restraint angle can also be adjusted manually.

Your vehicle is equipped with power head restraints, do
not try to raise or lower them manually.
Only minor personal adjustments, as described below,
should then be required.
For steering wheel adjustment, see page 73;
inside rear view mirror, see page 74;
exterior rear view mirrors, see page 75.
Caution!
Do not remove head restraints except when mounting
seat covers. For removal see page 46. Whenever
restraints have been removed be sure to reinstall them
before driving.Memory storing and recalling

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.

cluster displayPractical hints Car care Index Roll bar and head restraints, rear
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.
