PARTS
When replacing parts, use MITSUBISHI genuine parts
VEHICLE WASHING
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to maintain the
spray nozzle at a distance of at least 300 mm (11.8 in.) from
any plastic parts and all opening parts (doors, luggage
compartment, etc.).
SERVICING ELECTRICAL SYSTEM
1. Note the following before proceeding with work on the
electrical system.
Note that the following must never be done:
Unauthorized modifications of any electrical device or
wiring, because such modifications might lead to a vehicle
malfunction, over-capacity or short-circuit that could result
in a fire in the vehicle.
2. When servicing the electrical system, disconnect the
negative cable terminal from the battery.
Caution
1. Before connecting or disconnecting the negative
cable, be sure to turn off the ignition switch and the
fighting switch.
(If this is not done, there is the possibility of
semiconductor parts being damaged.)
2. After completion of the work steps [when the
battery’s negative (-) terminal is connected], warm
up the engine and allow it to idle for approximately
five minutes under the conditions described below,
in order to stabilize engine control conditions, and
then check to be sure that the idling is satisfactory.
For 3.OL Engine models: If the engine rpm is high,
switch OFF the ignition switch, and then, after
switching it ON again, let the engine idle for 2 or 3
minutes.
This will cause the engine rpm to decrease about
100 rpm, so repeat this procedure until the pre-
scribed idling speed is reached.
Engine coolant temperature : 85”-95°C (‘l85403”F)
Lights, accessories : OFF
Transmission : neutral position
(Automatic transmission models: “IV or “P”J
Steering wheel : neutral (center) position
