Warning!
G
In the case of an accident, liquid electrolyte 
may escape the mirror housing if the mirror 
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with 
eyes, skin, clothing, or respiratory system. 
In case it does, immediately flush affected 
area with water, and seek medical help if 
necessary.
Warning!
G
Exercise care when using the passenger 
side exterior rear view mirror. The mirror 
surface is convex (outwardly curved surface 
for a wider field of view). Objects in mirror 
are closer than they appear. Check your in-
terior rear view mirror or glance over your 
shoulder before changing lanes.!Electrolyte drops coming into contact 
with the vehicle paint finish can only be 
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.

69 Safety and Security
Occupant safety
Roll barThe roll bar raises automatically in an acci-
dent or in a critical driving situation. You 
can also raise and lower the roll bar manu-
ally using the buttons provided.
The buttons for the roll bar are on the cen-
ter console under the roof switch.
1Lower roll bar
2Raise roll bar
The roll bar can be moved manually when 
the ignition is switched on.Raising the roll bar
Lift the switch for the retractable hard-
top.
Press and hold button2 until the roll 
bar is raised.
Warning!
G
This vehicle is a two occupant vehicle. The 
rear storage area is not intended for use by 
occupants and is not equipped for properly 
seating or restraining occupants. Thus this 
area should never be used by any persons.
Before operating the roll bar switch make 
sure that the roll bar’s path is clear and no 
persons are injured by the moving roll bar 
due to inattention. Raising or lowering of the 
roll bar could injure someone inadvertently 
occupying the rear storage area.
For your own safety, we recommend to drive 
with the roll bar raised if the outside temper-
ature is below +5°F (-15°C).!If the outside temperature falls below 
+5°F (-15°C), the roll bar must be 
raised manually using the buttons pro-
vided to avoid damaging the hydraulics.
iWhen the roll bar is raised automatical-
ly, you will hear a ratcheting sound.
Warning!
G
If the roll bar warning light 
 
in the ta-
chometer remains lit after starting the en-
gine, there is a malfunction. In the display 
you see the message 
Raise the 
roll-over bar
.
For safety reasons, drive only with the roll 
bar upright until the malfunction is repaired. 
Have your vehicle checked at an authorized 
Mercedes-Benz Center.

79 Safety and Security
Driving safety systems
For more information, see the 
“Practical hints” section (
page 282).Switching off the ESP
To improve the vehicle's traction, turn off 
the ESP in driving situations where it would 
be advantageous to have the drive wheels 
spin and thus cut into surfaces for better 
grip such as:
starting out on slippery surfaces and in 
deep snow in conjunction with snow 
chains
in sand or gravelThe switch is located in the lower part of 
the center console.
1ESP switch
Press ESP switch1 until the ABS/ESP 
warning lamp v in the instrument 
cluster comes on.
ESP is deactivated.
!Because of the ESP’s automatic opera-
tion, the engine must be shut off 
(SmartKey in starter switch position 0 
or 1 or KEYLESS-GO* start/stop but-
ton in position 0 or 1) when
the parking brake is being tested on 
a brake test dynamometer
the vehicle is being towed with the 
front/rear axle raised
Active braking action through the ESP 
may otherwise seriously damage the 
brake system.
The ESP will only function properly if 
you use wheels of the recommended 
tire size (
page 378).
Warning!
G
ESP should not be switched off during nor-
mal driving other than in the circumstances 
described below. Disabling of the system 
will reduce vehicle stability in standard driv-
ing maneuvers.!Turn on the ESP immediately if the 
aforementioned circumstances do not 
apply anymore.
iDistronic* cannot be activated when 
the ESP has been deactivated.
