275 Operation
Driving instructions
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce
the normal brake effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking
efficiency should be tested as soon as
possible after driving is resumed.
For more information, see “Winter driving”
(
page 327).
Standing water
Warning!G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
Warning!G
If the vehicle becomes stuck in snow, make
sure that snow is kept clear of the exhaust
pipe and from around the vehicle with the
engine running. Otherwise, deadly carbon
monoxide (CO) gases may enter vehicle in-
terior resulting in unconsciousness and
death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle not facing the wind.
Warning!G
The outside temperature indicator is not de-
signed to serve as an Ice-Warning Device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice.
!Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force wa-
ter into the engine and auxiliary equipment, thus
damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake,
causing severe internal engine damage. Any
such damage is not covered by the
Mercedes-Benz Limited Warranty.

Replacing bulbs
Replacing bulbs
Bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp
assemblies are in good working order at
all times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Center for headlamp
adjustment.
Warning!G
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before chang-
ing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas.
A bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of high
humidity, driving the vehicle a distance with
the lights on should clear up the fogging.
iAuxiliary bulbs will be brought into use when
the following lamps malfunction:
Turn signal lamps
Brake lamps
Parking lamps
Tail lamps
Observe the messages in the multifunction
display (
page 359).
