R
regardless of whether the seat belt on the
impacted side of the vehicle is in use
R in certain vehicle rollovers, if the system
determines that air bag deployment can
offer
additional protection to that provided
by the seat belt
Window curtain air bags : are not deployed
in impacts which do not exceed the system’s
deployment threshold.
Window curtain air bags : deploy in the area
indicated by the arrows. Occupant Classification System
The
Occupant Classification System (OCS) is
standard equipment in USA.
The OCS activates or deactivates the front
passenger front air bag automatically. The
respective status is based on the classified
occupant weight category determined by
weight sensor readings from the front
passenger seat.
The system does not deactivate
R the front passenger side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices (ETDs)
To be classified correctly, the front passenger
must sit
R with the seat belt properly fastened
R in a position that is as upright as possible
with the back against the seat backrest
R with the feet on the floor
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
Furthermore, the occupant weight may
appear to increase or decrease due to the
following: objects hanging on the seat, lodged
underneath the seat, stuffed between the
seat and middle console or the seat and door,
other passengers pushing on the seat, or objects applying pressure to the back of the
seat. Always make sure the seat has
clearance in all directions at all times.
If your seat, including the trim cover and
cushion,

needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the front passenger
should always use the 42
indicator lamp as an indication of whether or
not the front passenger is properly
positioned. G
Warning!
If the 42 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 42 indicator lamp goes out,
or

check whether objects are caught under or
around the seat.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighting
as much as or less than a typical 12-month-
old child in a standard child restraint or if the
front passenger seat is classified as being
empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 42 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 42 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated. 42

Checking coolant temperature G
Warning!
Driving when your engine is 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 which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
X Press button & or * repeatedly until
the coolant temperature appears in the
multifunction display. During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†).
!
Excessive coolant temperature triggers a
warning in the multifunction display. The engine should not be operated with a
coolant temperature above 248‡
(120†). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Calling up digital speedometer or
outside temperature You can select whether the digital
speedometer or the outside temperature
appears in the multifunction display
(Y page 133).
G
Warning!
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. The road may still be icy,
especially in wooded areas or on bridges.
X Press button & or * repeatedly until
the digital speedometer or the outside
temperature appears in the multifunction
display. Digital speedometer
