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 292.
•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 237.
•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), the four wheel electronic
traction system (4-ETS+), the electronic stability
program (ESP), and electronic brake proportioning
(EBP) 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 using snow chains see
page 179.
Deep water
Caution!
Do not drive through flooded areas or water of unknown
depth. Before driving through water, determine its
depth. It should not be deeper than approximately
20 inches (50 cm).
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.

230 OperationWinter driving
Winter drivingBefore the onset of winter, have your vehi-
cle winterized at an authorized
Mercedes-Benz Light Truck 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 temperatures below freezing point
(page 307).


Battery test. 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.


Tire change. Mercedes-Benz recom-
mends M+S rated radial-ply tires with a
minimum tread depth of approximately 1/6in (4 mm) on all four wheels for the
winter season.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum ef-
fectiveness of the ABS, ESP, 4-ETS, and
EBP in winter operation.
For safe handling, ensure that all winter
tires mounted 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 ve-
hicle, you must place a notice to this effect
where it will be seen by the driver. Such no-
tices are available at your tire dealer or any
authorized Mercedes-Benz Light Truck
Center.Warning!
G
Winter tires with a tread depth under
1/6in
(4 mm) must be replaced. They are no long-
er 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 Light Truck Center.

Extended Activity Module - Task

n

The primary tasks of the Extended Activity Module (EAM, N10/1) are

as follows:
D
To control the door sill lights

D
To suppress the auto-dimming mirror function

D
To control the headlight cleaning system (HCS)

D
To control the rear window defroster

D
To control seat heating

D
To read the cruise control switch (S40) and relay data to control

module (DAS, N73/1)

D
To read the contacts for wiper speed settings 1 and 2 on

combination switch (S4) for diagnosis.

To perform these tasks the Extended Activity Module (EAM, N10/1)

reads various signals and switch settings directly.

The Extended Activity Module (EAM, N10/1) interfaces with other
control modules via the engine compartment CAN.

-----------------------------------------------------------------------------------------
Diagnosis

Diagnosis is performed using the Star diagnostic tool. To facilitate

this task, the Extended Activity Module (EAM, N10/1) is equipped

with its own diagnostics cable.
This cable is also used to diagnose the
All Activity Module (AAM,

N10)
and the
transfer case control module (N78)
.

The Extended Activity Module (EAM, N10/1) is linked to the All

Activity Module (AAM, N10) via the
engine compartment CAN
.

Data communication between the All Activity Module (AAM,

N10) and the Extended Activity Module (EAM, N10/1) is

assumed by the
CAN (N10 - N10/1)
when terminal 15 is off.

The CAN (N10 - N10/1)
is an independent CAN bus located

between the All Activity Module (AAM, N10) and the Extended

Activity Module (EAM, N10/1).
No other
control modules are

connected to the CAN (N10 - N10/1).

-----------------------------------------------------------------------------------------

to the HCS pump relay.

EAM will send an additional turn-on signal to the HCS pump relay

only after the cleaning operation is completed and a "rest period" of

approximately 2.5 sec. has passed.

Auto-dimming mirror function

The auto-dimming mirror function is suppressed when the interior

light is on or reverse gear is engaged.

Auto-dimming suppression for the outside rearview mirror (slave) is

activated by the inside rearview mirror (master).

Heater booster/PTC air heater for diesel engines

EAM monitors system voltage and adjusts heater booster capacity to

minimize load on battery.
