Night security illumination
At low ambient light conditions and with the engine
having been switched off, the exterior lamps (fog lamps
and parking lamps) switch on for added illumination,
(except in daytime running mode). After the last door
has been closed the lamp-on time period commences.
See the individual setting menu “LIGHTING” –
“HEADLAMPS DELAYED SWITCH–OFF” on page 128,
for instructions on how to activate the function.
The lamp-on time period for night security illumination
can be set at several different timed levels from 0 (off) to
60 seconds, see the individual setting menu
“LIGHTING” – “HEADLAMPS DELAYED SWITCH–OFF”
on page 128. Notes:
Within 10 minutes after closing the last door the night
security illumination can be reactivated by opening a

If after switching the engine off, no doors are opened or
if after opening the doors they are not closed, the night
security illumination will switch off automatically
after 60 seconds.
Deactivating night security illumination temporarily:
Turn the electronic key in starter switch to position 0

setting II. Have the system checked at your authorized
Mercedes-Benz Center as soon as possible. Windshield wipers smear
If the windshield wipers smear the windshield, even
during rain, activate the washer system as often as
necessary. The fluid in the washer reservoir should be
mixed in the correct ratio.
See page 320 for instructions on filling up the
windshield washer reservoir.
See page 356 for instructions on replacing wiper blade

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,
seepage379.
• 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 320.
• 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.
