E. Cautions
Use only specified Engine Oil (approved by MB Sheet 229.51) for CDPF. -
Use only specified engine oil (Low Ash Oil) ▶
The vehicle equipped with CDPF should use specific engine oil to improve the engine
performance and fuel economy, and ensure the service life of CDPF. -
Issue with normal engine oil ▶
Sulfur, one of the contents of engine oil is burned and generates soot that is not regenerated
by the DPF. This remains on the filter as ashes and keeps accumulating. Eventually, this
ashes will block the filter. -
Benefit for specified engine oil ▶
Minimized the sulfur content of engine oil which reduces the service life.
Improved fuel economy and emission level of CO2 with high performance and low viscosity.
Increased service life of engine oil with high resistance to temperature. -
-
-
Problems when using unspecified engine oil ▶
The service life of filter may be reduced by 30% or more by the ashes accumulated on the
filter.
The fuel economy may be reduced because of engine rolling resistance, frequent
regeneration of DPF. -
-
These problems are also caused by oil with high sulfur content, such as tax exemption oil
and heating oil, etc. *

2) On-engine Service
Disconnect the negative battery cable before removing or installing any electrical unit, or
when a tool or equipment could easily come in contact with exposed electrical terminals.
Disconnecting this cable will help prevent personal injury and damage to the vehicle. The
ignition must also be in LOCK unless otherwise noted. -
Any time the air cleaner is removed, the intake opening should be covered. This will protect
against accidental entrance of foreign material, which could follow the intake passage into
the cylinder and cause extensive damage when the engine is started. -

2. DESCRIPTION AND OPERATION
1) General Description
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions.
When the engine is cold, the cooling system cools the engine slowly or not at all. This slow
cooling of the engine allows the engine to warm up quickly.
The cooling system includes a radiator and recovery subsystem, cooling fans, a thermostat and
housing, a water pump, and a water pump drive belt. The timing belt drives the water pump.
All components must function properly for the cooling system to operation. The water pump
draws the coolant from the radiator. The coolant then circulates through water jackets in the
engine block, the intake manifold, and the cylinder head. When the coolant reaches the operating
temperature of the thermostat, the thermostat opens. The coolant then goes back to the radiator
where it cools.
This system directs some coolant through the hoses to the heat core. This provides for heating
and defrosting.
The coolant reservoir is connected to the radiator to recover the coolant displaced by expansion
from the high temperatures. The coolant reservoir maintains the correct coolant level.
The cooling system for this vehicle has no radiator cap or filler neck. The coolant is added to the
cooling system through the coolant reservoir.
2) Radiator
This vehicle has a lightweight tube-and-fin aluminum radiator. Plastic tanks are mounted on the
upper and the lower sides of the radiator core.
On vehicles equipped with automatic transaxles, the transaxle fluid cooler lines run through the
radiator tank.
A radiator drain plug is on this radiator.
To drain the cooling system, open the drain plug.
3) Coolant Reservoir
The coolant reservoir is a transparent plastic reservoir, similar to the windshield washer reservoir.
The coolant reservoir is connected to the radiator by a hose and to the engine cooling system by
another hose.
As the vehicle is driven, the engine coolant heats and expands. The portion of the engine coolant
displaced by this expansion flows from the radiator and the engine into the coolant reservoir. The
air trapped in the radiator and the engine is degassed into the coolant reservoir.
When the engine stops, the engine coolant cools and contracts. The displaced engine coolant is
then drawn back into the radiator and the engine. This keeps the radiator filled with the coolant to
the desired level at all times and increases the cooling efficiency.
Maintain the coolant level between the MIN and MAX marks on the coolant reservoir when the
system is cold.

3) PWM Electric Fan
(1) Advantages and Disadvantages of the PWM Electric Fan
Advantages ▶
Enhanced A/C performance: at low speed,
at idling, driving in city
Reduction of vibration/noise: fan activated
by PWM only when necessary
Reduction of engine consuming power
(V/Fan driving force) by 4 Hp - Cost
saving -
-
-
Disadvantage ▶
Poor engine cooling perfomance at low
and high rpm -
4) PWM (Pulse Width Modulation) Unit
It controls the time of the output voltage to
control the fan motor speed independently.
Internal functions ▶
Motor power shutting-off function when
overcurrent is applied
Adverse voltage prevention function
Detection function for the motor lock
Temperature detecting function: The
electric fan operates at FULL speed to
cool down the PWM unit when the interior
temperature of PWM unit is over
120~150°C.
Communication function when failing: The
fail signal is transmitted to the ECU when
the PWM unit is malfunctioning.
Soft start function: The motor speed is
gradually increased when the motor is
initially operated. -

The relays in the ICM box cannot be replaced respectively; so if the any of the
components on the PCB are defective, they should be replaced as an assembly.

3) Operating Process by Power Supply of ICM Box
(1) Door lock relay
The power supplied through the No. F53 interior fuse on the left-hand of the engine compartment
is on standby on the No. 86 and 87 door lock relay terminals and No. 86 and 87 door unlock relay
terminals via the ICM No. 12 terminal. The STICS activates and/or controls the door lock relay
connected to the ICM No. 15 terminal using the STICS No. B3 terminal depending on the
operating conditions. The activated door lock relay supplies the No. 30 terminal with the B+
power, which is standby on the No. 87 terminal and supplies each door actuator with the B+
power.
The supplied power flows to the G201 ground connected to the ICM No. 14 terminal via the No.
30 and 87a door unlock relays for corresponding load.

(2) Door unlock relay
The supply power is on standby in the same way as the door lock relay, and the STICS activates
and/or controls the door unlock relay connected to the ICM No. 6 terminal using the STICS No.
A1 terminal depending on the operating conditions. The activated door unlock relay supplies the
No. 30 terminal with the B+ power, which is standby on the No. 87 terminal and supplies each
door actuator with the B+ power.
The supplied power flows to the G201 ground connected to the ICM No. 14 terminal via the No.
30 and 87a door lock relays for corresponding load.
