tion appears in the tachometer display.
1Current automatic transmission posi-
tion!
If the automatic transmission position fails
in the tachometer display, you should check
whether the gear selector lever is placed in the
desired position while driving off with added cau-
tion. We recommend you to shift the gear selec-
tor lever to positionD. Do not limit the gear
range.
Effect
ì
Park position
Shift into park positionP only
when vehicle is stopped. The
park position is not intended to
serve as a brake when the vehi-
cle is parked. Rather, the driver
should always set the electric
parking brake in addition to shift-
ing into park positionP to secure
the vehicle.
If the vehicle’s electrical system
is malfunctioning, the automatic
transmission could remain
locked in park positionP.
Have the vehicle checked as
soon as possible by an autho-
rized Mercedes-Benz Center.
!
SmartKey:
If you turn off the engine using the SmartKey and
remove the SmartKey from the starter switch,
the automatic transmission will shift to park
positionP automatically. Keep in mind that turn-
ing off the engine with the SmartKey alone will
not automatically shift the automatic transmis-
sion to park positionP. Only when the SmartKey
is removed from the starter switch, will the auto-
matic transmission automatically shift to park
positionP.
KEYLESS-GO*:
If you turn off the engine using the KEYLESS-GO
start/stop button and open the driver’s door, the
automatic transmission will shift to park
positionP automatically. Keep in mind that turn-
ing off the engine using the KEYLESS-GO
start/stop button alone will not automatically
shift the automatic transmission to park
positionP. Only when the driver’s door is
opened, will the automatic transmission auto-
matically shift to park positionP.
DISTRONIC Plus*:
the transmission will shift to park positionP au-
tomatically, only when DISTRONIC Plus brings
your vehicle to a standstill, and when it meets at
least one of the following conditions at the same
time:
the engine is turned off
the driver’s or passenger door opens and the
seat belt is not engaged in the buckle
In addition to shifting to park positionP, the elec-
tric parking brake will be engaged automatically.

530 OperationWinter drivingBefore the onset of winter, have your
vehicle winterized at an authorized
Mercedes-Benz Center. This service
includes:
Check of anticorrosion and antifreeze
concentration.
Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“S” to a premixed windshield washer
solvent/antifreeze which is formulated
for below freezing temperatures
(page 666).
Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to make
sure that the engine can be started,
even at low ambient temperatures.
Tire change.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Not all M+S rated tires provide special winter performance.
Make sure the tires you use show the
mountain/snowflake.marking on the
tire sidewall. These tires meet specific
snow traction performance requirements
of the Rubber Manufacturers Association
(RMA) and the Rubber Association of Can-
ada (RAC) and have been designed specif-
ically for use in snow conditions. Use of
winter tires is the only way to achieve the
maximum effectiveness of the ABS, EBP
and ESP
® in winter operation.
For safe handling, make sure that all
mounted winter tires are of the same make
and have the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available from your tire
dealer or from any authorized
Mercedes-Benz Center.
Warning!
G
Winter tires with a tread depth under
1/6in
(4 mm) must be replaced. They are no
longer suitable for winter operation.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.
