GENERAL before Service
PRECAUTIONS BEFORE SERVICE.
SUPPLEMENTAL RESTRAINT SYSTEM
1. to follow when servicing SRS
(1) Be sure to read GROUP Supplemental Restraint System
For safe operations, please follow the directions a nd heed all
(2) Always use the designated special tools and tes t equipment.
(3) Wait at least 60 seconds after disconnecting the battery cable before” further work;
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the bat tery cable is disconnected.
(4) Never attempt to disassemble or repair the SRS components (SRS-ECU air bag module and
clock spring). If faulty, replace it.
(5) Warning labels must be heeded when servicing or handling SRS components. Warning labels
are located in the following locations.
Sun visor
l Glove box
. S R S - E C U
l Steering wheel
l Air bag module
l Clock spring
l Steering gear and linkage clamp
(6) Store components removed from the SRS
a clean and dry place.
The air bag module should be stored on a flat surfa ce and placed so that the pad surface is’
facing upward.
Do not place anything on top of it.
(7) Be sure to deploy the air bag before disposing of the air bag’module or disposing of a vehicle
equipped with an air bag. (Refer to GROUP
Air Bag Module Disposal Procedures.)
(8) Whenever you finish servicing the
check the SRS warning light operation to make sure
that the system functions properly.
2.Observe the following when carrying out operations on places where SRS components are installed,’
.,
including operations not directly related to the SR S air bag.
(1) When removing or installing parts do not allow any impact or shock to the SRS components.
(2) SRS components should not be subjected to heat over so remove the SRS compo-
nents before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lig ht operation to make sure that the system
functions properly.
SERVICING THE ELECTRICAL SYSTEM
1. Note the following before proceeding with work o n 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 co uld result
in a fire in the vehicle.
2.When servicing the electrical system, disconnect th e nega-
tive cable terminal from the battery.

GENERAL Precautions before Service . .
Caution
1.Before connecting or disconnecting the negative
be sure to turn off the ignition and
the lighting switch.
(if this is not done, the possibility semi-
conductor parts being damaged.)
2.After completion of the work steps [when the bat-
tery’s negative terminal is connected], warm
up the engine and allow it for approximately
five minutes under the conditions be-
low, in order to stabilize the engine condi-
tions, and then check to be sure that idling’ is
satisfactory.

GENERAL Lubrication arid Maintenance,
00100120067
Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum
protection for the vehicle owner’s investment
against all reasonable types of driving conditions.
Since these conditions vary with the individual ve-
hicle owner’s driving habits, the area in which the
vehicle is operated and the type of to which
the vehicle is subjected, it is necessary to prescr ibe
lubrication and maintenance service on a time fre-
quency as well as mileage interval basis.
Oils, lubricants and greases are classified and
graded according to standards recommended by
the Society of Automotive Engineers (SAE), the
American Petroleum Institute (API) and the National
Lubricating Grease Institute (NLGI).
MAINTENANCE SCHEDULES
Information for service maintenance is provided
under “SCHEDULED MAINTENANCE TABLE”.
Three schedules are provided; one for “Required
Maintenance”, one for “General Maintenance” and
one for “Severe Usage Service”. Item numbers in the “SCHEDULED MAINTE-
NANCE TABLE” correspond to the item
in the “MAINTENANCE SERVICE” section.
SEVERE SERVICE
Vehicles operating under severe service conditions
will require more frequent service. Component service information is included in ap-
propriate units for vehicles operating under one
or more of the following conditions:
1. Police, taxi, or commercial type operation
2. Operation of Vehicle
(1) Short-trip operation at freezing temperature
(engine not thoroughly warmed up)
(2) More than 50% operation in heavy city traf-
fic during hot weather above
(3) Extensive idling
(4) Driving in sandy areas
(5) Driving in salty areas
(6) Driving in dusty conditions
ENGINE OIL
Either of the following engine oils should be used:
(1) Engine oil displaying EOLCS certification mark
(2) Engine oil conforming to the API classification SH
or ECII.
For further details, refer to “LUBRICANTS SELEC-
TION” section.
Caution

any used engine oil. Do not use gasoline, thin- ners, or solvents.
GEAR LUBRICANTS
The SAE grade number indicates
of Multi-purpose Gear Lubricants.
The API classification system
cants in terms of gear lubricants
conforming to API
or ‘with a

transaxle.
LUBRICANTS GREASES
Semi-solid lubricants bear the
designation
and are further classified as grades 0, 1, 2; 3 etc .
Whenever “Chassis Lubricant” is specified, Multi-
purpose Grease,
grade 2, should be used.
FUEL USAGE
Your car must use unleaded
This car has a fuel filler tube especially
to accept only the smaller-diameter unleaded gaso- line dispensing nozzle.
Caution
Using leaded gasoline in your car will damage
the catalytic converter and oxygen sensor, and
affect the warranty coverage validity.
Your car is designed to operate on premium
leaded gasoline having a minimum octane rating
of 91 or 95 RON (Research Octane
If premium unleaded gasoline is not
leaded gasoline having a octane rating of 87,
91 RON (Research Octane Number) may be used. In this case, the performance and fuel consumption
will suffer a little degradation.
Gasolines Containing Alcohol
Some gasolines sold at service stations contain
alcohol, although they may not be so identified.
