Loading instructions
The total load weight including vehicle occupants and
luggage / cargo should not exceed the vehicle capacity
weight indicated on the certification label which can be
found on the left door pillar.
The handling characteristics of a fully loaded vehicle
depend greatly on the load distribution. It is therefore
recommended to load the vehicle according to the
illustrations shown, with the heaviest items being
placed towards the front of the vehicle.Always place items being carried against front or rear
seat backrests, and fasten them as securely as possible.
The heaviest portion of the cargo should always be kept
as low as possible against front or rear seat backrest
since it influences the handling characteristics of the
vehicle.
For additional safety when transporting cargo while the
rear seats are unoccupied, fasten the outer seat belts
crosswise into the opposite side buckles.

Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc..

Overlap Regulating Valve, Function
Operation - During the shift phase the pressure in the disengaging shift actuator is controlled depending on the
engine load (modulating pressure (p-Mod)) and the pressure in the engaging shift actuator. The regulated
pressure is inversely proportional to the transfer capacity of the activating shift actuator (regulated overlap). See
Fig. 78
.

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 control the power supply via control console to tilt/sliding or

louvered sunroof switch

D
To control the PTC heater booster (R22/3)

D
To control the auxiliary fan (M4)

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).

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

Details:

Door sill lights

When the front interior light is on and one of the front doors is open,

or when the rear interior light is on and one of the back doors is open,

the door sill lights for the open door will illuminate.

Headlight cleaning system (HCS)

Activating a separate switch causes the EAM to send a turn-on signal

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.
Rear window defroster

EAM sets maximum ON time for rear window defroster depending

on outdoor temperature and current vehicle speed.
D
Standard ON time:
10 min.

D
Outdoor temperature < 5
o
C:
Additional 5 min.

D
Speed >80 km/h:
Additional 3 min.

Seat heating

Sets maximum seat heating time.
D
Setting 1: max. 20 min.

D
Setting 2: max. 5 min.

Tilt/sliding or louvered sunroofs

Signal via AAM2 allows operation of tilt/sliding or louvered sunroofs

when ignition is on (standard mode) or off (keyless mode).

Ignition authorization via CAN

The EAM issues ignition authorization to AAM2 via the engine

compartment CAN depending on the requirements of the engine

control unit in connection with the FBM.

Fig. 110: Identifying Refrigerant Compressor Control Valve, Function (1 Of 2)
Variable volume control in partial load range
(e.g. at low ambient temperature or low cooling capacity requirement)
Essentially, the cooling output is dependent on the intake pressure, i.e. if the suction pressure (Ps) drops below
the diaphragm pressure (Ps1) in the refrigerant compressor control valve and the regulating current is reduced at
the same time, then the passage from high pressure (Pd) to crankcase pressure (Pc) is released by the control
plunger (2) in the refrigerant compressor control valve. As a result, refrigerant flows from the high pressure side
into the crankcase which results in an increase in crankcase pressure (Pc).
The sum of the forces on the left-hand side, resulting from the crankcase pressure (Pc), the return force
(centrifugal force) of the swash plate and the spring return force thus becomes greater than total piston forces.
The swash plate moves into a vertical position, which causes a reduction in piston travel and replacement
volume.
In addition, a regulation of the cooling output takes place as a function of the air humidity, i.e. at high air
humidity there is an external actuation of the control valve, achieving a post-regulation of the cooling output
(preventing fogging up of the windows).
The refrigerant compressor is automatically switched off at a volumetric flow of less than 5 cm
3.
