WARNINGS REGARDING SERVICING OF SUPPLEMENTAL
RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
(1) Improper service or maintenance of any component of the SRS or any SRS-related component,
can lead to personal injury or death to service personnel (from inadvertent firing of the air bag)
or to the driver and passenger (from rendering the SRS inoperative).
(2) The SRS components and seat belt with pretensioner should not be subjected to heat, so
remove the SRS-ECU, driver’s and front passenger’s air bag modules, clock spring, side air bag
modules, and seat belt -pre-tensioner before drying or baking the vehicle after painting.
• SRS-ECU, air bag module and clock spring 93°C or more
• Seat belt with pre-tensioner: 90°C or more
(3) Service or maintenance of any SRS component or SRS-related component must be performed
only at an authorized MITSUBISHI dealer.
(4) MITSUBISHI dealer personnel must thoroughly review this Manual, and especially its GROUP
52B - Supplemental Restraint System (SRS), before beginning any service or maintenance of
any component of the SRS or any SRS-related component.

Section titles with asterisks (*) in the table of contents in each group indicate operations requiring warnings.

GENERAL INFORMATION
ENGINE LUBRICATION12-2
GENERAL INFORMATION
M1121000100357
The lubrication method is a fully force-fed, full-flow
filtration type. The engine oil pump is a trochoid type
which is driven by the crankshaft <4G1>.The engine
oil pump is a gear type which is driven by the
crankshaft via the balancer timing belt <4G6>.
ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In
addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by
using enclosed systems for handling used engine oil
and by degreasing components, where practicable,
before handling them. Other precautions:
•Avoid prolonged and repeated contact with oils,
particularly used engine oils.
•Wear protective clothing, including impervious
gloves where practicable.•Avoid contaminating clothes, particularly
underpants, with oil.
•Do not put oily rags in pockets, the use of overalls
without pockets will avoid this.
•Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.
•Where there is a risk of eye contact, eye
protection should be worn, for example, chemical
goggles or face shields; in addition an eye wash
facility should be provided.
•Obtain first aid treatment immediately for open
cuts and wounds.
•Wash regularly with soap and water to ensure all
oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin oils
is advised.
•Do not use petrol, kerosine, diesel fuel, gas oil,
thinners or solvents for cleaning skin.
•Use barrier creams, applying them before each
work period, to help the removal of oil from the
skin after work.
•If skin disorders develop, obtain medical advice
without delay.

IGNITION SYSTEM
ENGINE ELECTRICAL16-30
IGNITION SYSTEM
GENERAL INFORMATIONM1163000100294
This system is equipped with two ignition coils (A and
B) with built-in power transistors for the No. 1 and
No. 4 cylinders and the No. 2 and No. 3 cylinders
respectively.
Interruption of the primary current flowing in the
primary side of ignition coil A generates a high
voltage in the secondary side of ignition coil A. The
high voltage thus generated is applied to the spark
plugs of No. 1 and No. 4 cylinders to generate
sparks. At the time that the sparks are generated at
both spark plugs, if one cylinder is at the
compression stroke, the other cylinder is at the
exhaust stroke, so that ignition of the compressed
air/fuel mixture occurs only for the cylinder which is
at the compression stroke.
In the same way, when the primary current flowing in
ignition coil B is interrupted, the high voltage thus
generated is applied to the spark plugs of No. 2 and
No. 3 cylinders.The engine-ECU or engine-A/T-ECU
turns the two power transistors inside the ignition
coils alternately on and off. This causes the primary
currents in the ignition coils to be alternately
interrupted and allowed to flow to fire the cylinders in
the order 1-3-4-2.
The engine-ECU or engine-A/T-ECU
determines which ignition coil should be controlled
by means of the signals from the camshaft position
sensor which is incorporated in the camshaft and
from the crank angle sensor which is incorporated in
the crankshaft. It also detects the crankshaft position
in order to provide ignition at the most appropriate
timing in response to the engine operation
conditions. It also detects the crankshaft position in
order to provide ignition at the most appropriate
timing in response to the engine operation
conditions.
When the engine is cold or operated at high
altitudes, the ignition timing is slightly advanced to
provide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce
output torque, thereby alleviating shifting shocks.
