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.

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.

ON-VEHICLE SERVICE
ENGINE OIL CHECKM1121000900342
1. Pull out the engine oil level gauge slowly and 
check that the oil level is in the illustrated range.
2. Check that the oil is not excessively dirty, that 
there is no coolant or petrol mixed in, and that it 
has sufficient viscosity.
ENGINE OIL REPLACEMENTM1121001000416
1. Start the engine and allow it to warm up until the 
temperature of the coolant reaches 80 °C to 90 
°C.
2. Remove the engine oil filler cap.
CAUTION
Use care as engine oil could be hot.
3. Remove the engine oil pan drain plug to drain 
engine oil.4. Install a new engine oil pan drain plug gasket so 
that it faces in the direction shown in the 
illustration, and then tighten the engine oil pan 
drain plug to the specified torque.
Tightening torque: 39 ± 5 N⋅m
NOTE: Install the engine oil pan drain plug gasket 
so it faces in the direction shown in the illustration.
5. Refill with specified quantity of engine oil.
