If the battery is weak or terminated, the battery from another vehicle can be used with jumper
cables to start the engine.
Connecting order ▶
The positive (+) terminal of the discharged battery
The positive (+) terminal of the booster battery

Starting ▶
Prepare a set of jumper cables.
Place another vehicle that has the same 12 V of power near to the discharged vehicle.
Switch off all electrical accessories for the discharged vehicle.
Apply the parking brake and shift the transaxle to the P position (automatic transaxle) or neutral
(N) position (manual transaxle).
Connect the jumper cables.
Try to start the discharged vehicle while accelerating the engine rpm in the booster vehicle.
Attempt to start the engine with the discharged battery.

(8) Swirl control
A. Overview
Variable swirl valve ▶
The strong swirl caused by intake air is important element for anti-locking function in diesel engine. The
swirl control valve partially closes the intake port to generate the swirl according to the engine conditions.
When the engine load is in low or medium range, the swirl could not be generated because the air flow is
slow. To generate strong swirl, there are two passages in intake manifold, and one of them has the valve
to open and close the passage. When the valve closes the passage, the air flow through the another
passage will be faster, and the strong swirl will be generated by the internal structure of the passage. This
swirl makes the better mixture of air and fuel, eventually the combustion efficiency in combustion
chamber could be improved. This provides the enhanced fuel consumption, power and EGR ratio.

A. Overview of cooling fan and A/C compressor
The cooling system maintains the engine temperature at an efficient level during all engine operating
conditions. 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. The heat from automatic transmission is also cooled down through the radiator
by circulating the oil through the oil pump. ECU controls the electric cooling fans with three cooling fan
relays to improve the engine torque and air conditioning performance.
For detailed information, refer to Chapter "Air Conditioning System".

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. DESCRIPTION AND OPERATION
1) Cleanliness and Care
An automobile engine is a combination of many machined, honed, polished and lapped surfaces
with tolerances that are measured in the ten-thousanths of an inch. When any internal engine
parts are serviced, care and cleanliness are important. A liberal coating of enigne oil should be
applied to friction areas during assembly, to protect and lubricate the surfaces on initial operation.
Proper cleaning and protection of machined surfaces and friction areas is part of the repair
procedure. This is considered standard shop practice even if not specifically stated.
Whenever valve train components are removed for service, they should be kept in order.
They should be installed in the same locations, and with the same mating surfaces, as when they
were removed. Battery cables should be disconnected before any major work is performed on the
engine. Failure to disconnect cables may result in damage to wire harness or other electrical
parts.
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.
Notice Any time the air cleaner is removed, the intake opening -
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.g -

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.

Make sure a connector is connected
securely. Loose connection results in
malfunction. -
When inspecting the airbag system, make
sure to use a diagnostic device, not a
circuit tester.When disconnecting a connector equipped
with a lock, press it down to the direction in
the below figure. -
When checking voltage or continuity of the
connector terminal with a circuit tester,
connect the tester probe to the terminal at
the harness side. For a sealed type
connector, connect the probe to the
terminal through the hole in the rubber cap
of the wiring. Take care not to damage the
insulation of the wires. Insert the probe until
it contacts the terminal completely. -
