FUEL WARNING LAMP (See P.B-156.)
OIL PRESSURE WARNING LAMP (See P.B-157.)
BRAKE WARNING LAMP (See P.B-157.)
OPERATION
DWhen the ignition switch is at the “ON” position,
the fuel gauge unit resistance is small when
the fuel level is high, and the fuel gauge unit
resistance is large when the fuel level is low.
When this resistance rises above a specified
value, the fuel warning lamp illuminates to notify
the driver that the fuel level is low.
DWhen the lubrication system fails after engine
starting, resulting in the oil pressure failing to
build up, the oil pressure switch turns on
causing the oil pressure warning lamp to
illuminate.
DWhen the brake fluid level goes down below
a predetermined level with the ignition switch
in the “ON” position, the brake fluid level switch
is activated or the parking brake switch is turned
on, causing the brake warning lamp to
illuminate.TROUBLESHOOTING HINTS
1. No warning lamps illuminate.
DCheck multi-purpose fuse No.(2).
2. Some warning lamps do not illuminate.
DCheck lamp valve.
DCheck the switches and the gauge unit.

GENERAL -Precautions Before ServiceGENERAL -Precautions Before Service00-19
SERVICING THE ELECTRICAL SYSTEM
Before replacing a component related to the electrical system
and before undertaking any repair procedures involving the
electrical system, be sure to first disconnect the negative
( - ) cable from the battery in order to avoid damage caused
by short-circuiting.
Caution
Before connecting or disconnecting the negative ( - ) cable,
be sure to turn off the ignition switch and the lighting
switch.
(If this is not done, there is the possibility of
semiconductor parts being damaged.)
APPLICATION OF ANTI-CORROSION AGENTS
AND UNDERCOATS
If oil or grease gets onto the oxygen sensor, it will cause
a drop in the performance of the sensor.
Cover the oxygen sensor with a protective cover when applying
anti-corrosion agents and undercoats.
PRE-INSPECTION CONDITION
“Pre-inspection condition” refers to the condition that the
vehicle must be in before proper engine inspection can be
carried out. If you see the words “Set the vehicle to the
pre-inspection condition”. in this manual, it means to set the
vehicle to the following condition.
DEngine coolant temperature: 80 to 90_C
DLamps, electric cooling fan and all accessories: OFF
DM/T: Neutral
DA/T: P range
VEHICLE WASHING
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to note the
following information in order to avoid damage to plastic
components, etc.
DSpray nozzle distance: Approx. 40 cm or more
DSpray pressure: 3,900 kPa or less
DSpray temperature: 82_C or less
DTime of concentrated spray to one point: within 30 sec.

MUT-II
Refer to the “MUT-IIREFERENCE MANUAL” or “MUT-II
OPERATING INSTRUCTIONS” for instructions on handling
the MUT-II.
Connect the MUT-IIto the diagnosis connector as shown
in the illustration.
Caution
Turn the ignition switch to the LOCK (OFF) position before
connecting or disconnecting the MUT-II.
IN ORDER TO PREVENT VEHICLES FROM FIRE
“Improper installation of electrical or fuel related parts could cause a fire. In order to retain the high
quality and safety of the vehicle, it is important that any accessories that may be fitted or modifications/repairs
that may be carried out which involve the electrical or fuel systems, MUST be carried out in accordance
with MMC’s information/Instructions”.
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:
DAvoid prolonged and repeated contact with oils, particularly used engine oils.
DWear protective clothing, including impervious gloves where practicable.
DAvoid contaminating clothes, particularly underpants, with oil.
DDo not put oily rags in pockets, the use of overalls without pockets will avoid this.
DDo not wear heavily soiled clothing and oil-impregnated foot-wear. Overalls must be cleaned regularly
and kept separately from personal clothing.
DWhere 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.
DObtain First Aid treatment immediately for open cuts and wounds.
DWash 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.
DDo not use petrol, kerosine, diesel fuel, gas oil, thinners or solvents for cleaning skin.
DUse barrier creams, applying them before each work period, to help the removal of oil from the skin
after work.
DIf skin disorders develop, obtain medical advice without delay.
