Seat belt nonusage warning system
With the electronic key in starter switch position 2, a
warning sounds for a short time if the driver’s seat belt
is not fastened.
Automatic comfort-fit seat belt:
An automatic comfort-fit feature for all seat belt is
activated when the electronic key in the starter switch is
turned to position 1 or 2.
The retraction force of the inertia reel is reduced,
increasing the level of seat belt comfort.
Note:
For cleaning and care of the seat belts see page 389.
Wa r n i n g !
Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.

Te ch n i c a l

cluster displayPractical hints Car care Index Infant and child restraint systems
We recommend all infants and children be properly
restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver’s seat belt have
special seat belt retractors for secure fastening of child
restraints.
To activate, pull shoulder belt out completely and let it
retract. During the seat belt retraction a ratcheting
sound can be heard to indicate that the special seat belt
retractor is activated. The belt is now locked.
To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner
Note:
For child seats with mounting fittings for tether
anchorages refer to page 101 (installation of infant and
child restraint systems).Important!
The use of infant or child restraints is required by law in
all 50 states and all Canadian provinces.
Infants and small children should be seated in an
appropriate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint system, be sure
to carefully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels affixed to inside
of vehicle and to infant or child restraints.
Wa r n i n g !
Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.

Te ch n i c a l

cluster displayPractical hints Car care Index Coolant temperature gauge (5)
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 (6)
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.).
Adaption 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.
Note:
The unit for the temperature indicator display can be set
in the individual setting menu “INST. CLUSTER” –
“TEMP. INDICATOR” on page 140.
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.
