13 IntroductionWhere to find it
The Operator’s Manual is divided into eight sections:
• Instruments and controls: An overview of all the controls that can be operated from the driver’s seat.
•Operation: Information on the vehicle’s equipment and its operation.
•Driving: Important information on driving.
• Instrument cluster display: Displays and indicator lamps on the instrument cluster with brief instructions.
• Practical hints: Assistance and instructions in the event of an emergency.
• Car care: Instructions on caring for your vehicle.
• Technical data: All the important technical data for your vehicle as well as consumer information such as fuels,
coolants, lubricants etc. is contained here.
•Index: Key terms to help you find a topic quickly.
Other documents may also be supplied, depending on your vehicle’s equipment.
Explanation of color used:
Warning notices for the protection of yourself and
others appear on red background.

Coolant temperature gauge (3)
During severe operating conditions and stop-and-go city
traf f ic, th e coola nt tempera ture may rise close to th e 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 (5)
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.).
Adaptation 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.
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.

Winter driving
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, see
page 317.
•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 259.
•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.In winter operation, the maximum effectiveness of the
antilock brake system (ABS) or of the 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.
For driving instructions with snow chains, see page 210.
Deep water
Caution!
Do not drive t hrou gh f lood ed a rea s or water of u nk nown
depth.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.
Block heater (Canada only)
The engine is equipped with a block heater.
The electrical cable may be installed at your authorized
Mercedes-Benz Center.
