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.

backrest of the sliding seat is pushed against an
occupant or object. The seat will slide forward, stop, and
make 3 attempts sliding backward.
To halt the automatic process, activate the power seat
switch. Investigate and correct the cause of interruption.
Now use memory button or power seat switch to bring
seat into desired position.
The backrest release lever (1) also serves as a rest for
the front seat belt, bringing it within easy reach.
Wa r n i n g !

electronic key from the steering lock, and lock your
vehicle.The power seats can also be operated with the
driver’s or passenger door open. Do not leave
children unattended in the vehicle or with access
to an unlocked vehicle. Unsupervised use of vehicle
equipment may cause an accident and/or serious
personal injury.Never place hands under seat or near any moving
parts during a seat adjustment procedure.

Coolant temperature gauge (3)
During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to the red
marking.
The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.Outside temperature indicator (5)
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).
Adaptation to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of
temperature change.
Wa r n i n g !
• Driving when your engine is badly 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 engine hood. Stay away from the engine if
you see or hear steam coming from it.Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.
Wa r n i n g !
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.
