Important safety notes
!
Make sure that there are no objects in the
footwell or behind the seats. There is a risk
that the seats and/or the objects could be
damaged when PRE-SAFE ®
is activated.
Although your vehicle is equipped with PRE-
SAFE ®
, the possibility of injury in the event of an
accident cannot be ruled out. Always adapt your
driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under- steers or oversteers severely
R on vehicles with the Driving Assistance pack-
age: if BAS PLUS intervenes powerfully or the
radar sensor system detects an imminent
danger of collision in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detected:
R the front seat belts are pre-tensioned
R if the vehicle skids, the front side windows are
closed
R vehicles with the memory function: the front-
passenger seat is adjusted if it is in an unfav-
ourable position
R vehicles with a multicontour seat: the air pres-
sure in the side bolsters of the backrest is
increased
If the hazardous situation passes without result-
ing in an accident, PRE-SAFE ®
slackens the belt
pre-tensioning. On vehicles with multicontour
seats, the air pressure in the side bolsters is
reduced again. All settings made by PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back slightly
when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Informa-
tion about the convenience function can be
found under "Belt adjustment" (Y page 41). PRE-SAFE
®
PLUS (anticipatory occu-
pant protection PLUS)
Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-end collision is imminent. In certain hazardous sit-
uations, PRE-SAFE ®
PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned before the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and there
is a risk of a rear-end collision
When driving, or when parking or exiting a park- ing space with assistance from Active Parking
Assist, PRE-SAFE ®
PLUS will not apply the
brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta-
tionary
- the seat belts are pre-tensioned 48

objects, for example
There is a risk of fire and injury.
Always hold the cigarette lighter by the knob.
Always make sure that the cigarette lighter is
out of reach of children. Never leave children unattended in the vehicle.
Your attention must always be focused on the
traffic conditions. Only use the cigarette lighter when road and traffic conditions permit.

General notes X
Turn the key to position 1in the ignition lock
(Y page 139).
The sockets can be used for accessories with a
maximum draw of 180 W(15 A). Accessories
include such items as mobile phone chargers.
If you use the sockets for long periods when the engine is switched off, the battery may dis-
charge.
An emergency cut-off ensures that the on-boardvoltage does not drop too low. If the on-board
voltage is too low, the power to the sockets is
automatically cut. This ensures that there is suf-
ficient power to start the engine.

Important safety notes G
WARNING
Operating mobile communications equip-
ment while driving distracts you from paying
attention to traffic conditions. This could also cause you to lose control of the vehicle. There
is a risk of an accident.
Use this device only when the vehicle is sta-
tionary.
You must observe the legal requirements for the country in which you are currently driving when
operating mobile communications equipment in the vehicle.
If it is permitted by law to operate communica-
tions equipment while the vehicle is in motion,
you may only do so if the traffic situation per-
mits. You may otherwise be distracted from the
traffic conditions, cause an accident and injure
yourself and others.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus-
sion surrounding the possible health risk posed
by electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in the
vehicle
R that mutual interference between the vehicle
electronics and mobile phones is minimised Features
