tensioning retractor and airbag
Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.
• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical /
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free from objects (e.g.
packages, purses, umbrellas, etc).• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.

cluster displayPractical hints Car care Index Outside temperature indicator (17)
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 uni t for the temp erature in di cator d is play can b e set
in the individual setting menu “INSTRUMENT
CLUSTER” – “TEMP. INDICATOR” on page 121.Trip odometer (13)
To reset to “0” miles / km:
Activate the instrument cluster if it is not already
activated, see page 100.
Press button è or ÿ on the multifunction
steering wheel repeatedly until the trip odometer
appears if it is not displayed. See page 106.
Press button (1) on the instrument cluster, see page 100.
Tachometer (2)
The red marking on the tachometer denotes excessive
engine speed.
Avoid this engine speed, as it may result in serious
engine damage that is not covered by the
Mercedes-Benz Limited Warranty.
To help protect the engine, the fuel supply is interrupted
if the engine is operated within the red marking.
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.

Basic setting – automatic mode
In the automatic mode the climate control cools or heats
the interior depending on outside temperature and the
selected interior temperature. With the automatic mode
switched off, the air volume and distribution can still be
set manually.
Press U button. Air volume and distribution are
controlled automatically.
We recommend to set the left and right temperature
to 72
°F (22
°C). Please make changes from this setting to
suit your personal requirements.
Heating mode:
To lower headroom temperature, use thumbwheel
(4, page 152).

Notes:
Do not obstruct the air f low by placing objects on the air
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield
free of snow and debris.
The storage compartment between the front seats can be
ventilated. See page 171 for notes on ventilating the
storage space under the armrest in the center console.
The air conditioner switches itself off for its own
protection if refrigerant is lost. No cooling will then take
place. Economy mode S can n ot be s witched of f. Have
the air conditioner checked by a Mercedes-Benz Center
should this happen.
If the vehicle interior has been heated by direct sunlight
and is very hot, ventilate the interior (open door or
windows for a short period) before driving off.
Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.Basic setting – automatic mode
In the automatic mode the automatic climate control
cools or heats the interior depending on the direction
and strength of the sunlight, outside temperature and
the selected interior temperature of the vehicle. With
the automatic mode switched off, the air volume and
distribution can still be set manually.
Briefly press left or right U button. The h, j
and k symbols will no longer be visible.
The economy mode and air recirculation functions will
be switched off. The automatic blower will be activated
at the same time.
We recommend to set the temperature switches on the
left and right to 72
°F (22

this setting to suit your personal requirements.

Have your vehicle winterized at your authorized
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE / CCMC class) and filling quantity,
seepage383.
•Check engine coolant anticorrosion / antifreeze
concentration.
•Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent / antifreeze
which is formulated for below freezing
temperatures, see page 323.
•Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.Note:
In winter operation, the maximum effectiveness of the
antilock brake system (ABS) and electronic stability
program (ESP) can only be achieved with M+S rated
radial-ply tires and / or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.

Notes:
If the engine does not brake the vehicle sufficiently
while driving on a downgrade, the speed you set on the
cruise control may be exceeded. In this case the
following will assist in maintaining the set cruise
controlled speed:Vehicles with automatic transmission:
Downshift occurs (max. to 3rd gear) to maintain the set
cruise controlled speed by using the engine’s braking
power.
As soon as the grade eases, the automatic transmission
shifts up again dependent on the selector lever position.
Vehicles with manual transmission:
The set cruise controlled speed is switched off when
declutching exceeds four seconds during downshifting a
gear.
Nevertheless, in some cases you may have to step on the
brake pedal to slow down. In this case the cruise control
is switched off.
Use the lever to resume the previously set speed.
Wa r n i n g !
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.
• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.
