0A-3 General Information:

Wire Color Symbols

S6JB0B0101003

There are two kinds of colored wire used in this vehicle.
One is single-colored wire and the other is dual-colored
(striped) wire. As the color symbol, the single-colored
wire uses only one, three or five alphabets (i.e. “G” or
“GRN”); the dual-colored wire uses two color symbols
combination (i.e. “G/Y” or “GRN/YEL”). The first symbol
represents the base color of the wire (“G” or “GRN” in
the figure) and the second symbol represents the color
of the stripe (“Y” or “YEL” in the figure).

Fastener Information

S6JB0B0101004

Metric Fasteners
Most of the fasteners used for this vehicle are metric. When replacing any fasteners, it is most important that
replacement fasteners be the correct diameter, thread pitch and strength.

Fastener Strength Identification
Most commonly used metric fastener strength property classes are 4T, 6.8, 7T, 8.8 and radial line with the class
identification embossed on the head of each bolt. Some metric nuts will be marked with punch, 6 or 8 mark strength
identification on the nut face. Figure shows the different strength markings.
When replacing metric fasteners, be careful to use bolts and nuts of the same strength or greater than the original
fasteners (the same number marking or higher). It is likewise important to select replacement fasteners of the correct
diameter and thread pitch. Correct replacement bolts and nuts are available through the parts division.
Metric bolts: Identification class numbers or marks correspond to bolt strength (increasing numbers represent
increasing strength).

Standard Tightening Torque
Each fastener should be tightened to the torque specified in each section of this manual. If no description or
specification is provided, refer to the following tightening torque chart for the applicable torque for each fastener. When
a fastener of greater strength than the original one is used, however, use the torque specified for the original fastener.

NOTE

• For the flanged bolt, flanged nut and self-lock nut of 4T and 7T strength, add 10% to the tightening

torque given in the following chart.

• The following chart is applicable only where the fastened parts are made of steel light alloy.

Vehicle Lifting Points

S6JB0B0101005

WARNING

• Before applying hoist to underbody, always take vehicle balance throughout service into

consideration. Vehicle balance on hoist may change depending of what part to be removed.

• Before lifting up the vehicle, check to be sure that end of hoist arm is not in contact with brake pipe,

fuel pipe, bracket or any other part.

• When using frame contact hoist, apply hoist as shown (right and left at the same position). Lift up

the vehicle till 4 tires are a little off the ground and make sure that the vehicle will not fall off by
trying to move vehicle body in both ways. Work can be started only after this confirmation.

• Make absolutely sure to lock hoist after vehicle is hoisted up.

General Information: 0A-6

When Using Floor Jack

WARNING

• If the vehicle to be jacked up only at the

front or rear end, be sure to block the
wheels on ground in order to ensure
safety.
After the vehicle is jacked up, be sure to
support it on stands. It is extremely
dangerous to do any work on the vehicle
raised on jack alone.

CAUTION

• Never apply jack against engine under

cover, suspension parts (i.e., stabilizer,
etc.) or vehicle floor, or it may get
damaged.

In raising front or rear vehicle end off the floor by jacking,
be sure to put the jack against the center portion of the
front suspension frame (1) or rear differential (2).

To perform service with either front or rear vehicle end
jacked up, be sure to place safety stands (1) under
chassis frame so that body is securely supported.
And then check to ensure that chassis frame does not
slide on safety stands (1) and the vehicle is held stable
for safety’s sake.
