POSITIVE CRANKCASE VENTILATION SYSTEM : Work Procedure

INFOID:0000000009651634

1.

CHECK PCV VALVE

With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
placed over valve inlet.
Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace PCV valve. Refer to .

INFOID:0000000009651635

1.

Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration. Refer to 

EC-457, "Work Procedure"

.

2.

Inspect fuel tank filler cap vacuum relief valve for clogging, sticking, etc.
Refer to

EXHAUST SYSTEM

EXHAUST SYSTEM : Inspection

INFOID:0000000009651636

Check exhaust pipes, muffler, and mounting for improper attach-
ment, leakage, cracks, damage or deterioration.
• If anything is found, repair or replace damaged parts.

CVT FLUID

CVT FLUID : Inspection

INFOID:0000000009651637

CHECKING CVT FLUID

The fluid level should be checked with the fluid warmed up to 50 to 80

°

C (122 to 176

°

F). The fluid level check

procedure is as follows:

1.

Check for fluid leakage.

2.

With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20

°

C (68

°

F), it takes about 10

minutes for the CVT fluid to warm up to 50 to 80

°

C (122 to

176

°

F).

3.

Park the vehicle on a level surface.

4.

Apply parking brake firmly.

5.

With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.

6.

Pull out the CVT fluid level gauge from the CVT fluid charging
pipe after pressing the tab on the CVT fluid level gauge to
release the lock.

7.

Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid
level gauge rotating 180

°

 from the originally installed position,

then securely push the CVT fluid level gauge until it meets the
top end of the CVT fluid charging pipe.

CAUTION:

When wiping away the CVT fluid level gauge, always use
lint-free paper, not a cloth rag.

8.

Place the selector lever in “P” or “N” and check that the fluid
level is within the specified range.

CAUTION:

When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until securely locked.

CVT FLUID CONDITION

Check CVT fluid condition.
• If CVT fluid is very dark or smells burned, check operation of CVT.

Flush cooling system after repair of CVT.

• If CVT fluid contains frictional material (clutches, brakes, etc.),

replace radiator and flush cooler line using cleaning solvent and
compressed air after repair of CVT. Refer to 

TM-151, "Cleaning"

.

CVT FLUID : Changing

INFOID:0000000009939019

CAUTION:

Replace a O-ring with new ones at the final stage of the operation when installing.
1.

Remove drain plug from oil pan.

2.

Remove O-ring from drain plug.

3.

Install O-ring to drain plug.

CAUTION:

Never reuse O-ring.

4.

Install drain plug to oil pan. Refer to 

TM-164, "Exploded View"

.

5.

Fill CVT fluid from CVT fluid charging pipe to the specified level.

CAUTION:

• Use only recommended CVT fluid. Never mix with other fluid.
• Using CVT fluid other than Genuine recommended CVT fluid will deteriorate in driveability and

CVT durability, and may damage the CVT, which is not covered by the warranty.

• When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
• Sufficiently shake the container of CVT fluid before using.
• Delete CVT fluid deterioration date with CONSULT after changing CVT fluid. Refer to 

TM-35,

"CONSULT Function"

.

6.

With the engine warmed up, drive the vehicle in an urban area.
NOTE:
When ambient temperature is 20

°

C (68

°

F), it takes about 10 minutes for the CVT fluid to warm up to 50 to

80

°

C (122 to 176

°

F).

7.

Check CVT fluid level and condition.

Fluid status

Conceivable cause

Required operation

Varnished (viscous 
varnish state)

CVT fluid becomes 
degraded due to 
high temperatures.

Replace the CVT fluid and check the 
CVT main unit and the vehicle for 
malfunctions (wire harnesses, cool-
er pipes, etc.)

Milky white or 
cloudy

Water in the fluid

Replace the CVT fluid and check for 
places where water is getting in.

Large amount of 
metal powder mixed 
in

Unusual wear of 
sliding parts within 
CVT

Replace the CVT fluid and check for 
improper operation of the CVT.

WHEELS

WHEELS : Wheel Balance Adjustment

INFOID:0000000009651638

PREPARATION BEFORE ADJUSTMENT

Using releasing agent, remove double-faced adhesive tape from the road wheel.

CAUTION:

• Be careful not to scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road

wheel.

ADJUSTMENT (ALUMINUM WHEEL)

• The details of the adjustment procedure are different for each model of wheel balancer. Therefore, refer to

each instruction manual. 

• If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,

select and adjust a drive-in weight mode suitable for aluminum wheels.

1.

Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.

2.

When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer
unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value above and install to the designated outer position of, or at the
designated angle in relation to the road wheel.

CAUTION:

• Never install the inner balance weight before installing the outer balance weight.
• Before installing the balance weight, always clean the mating surface of the road wheel.

a.

Indicated unbalance value 

×

 5/3 = balance weight to be installed

Calculation example:
23 g (0.81 oz) 

×

 5/3 = 38.33 g (1.35 oz) 

⇒

 37.5 g (1.32 oz) bal-

ance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
36.2 

⇒

 35 g (1.23 oz)

36.3 

⇒

 37.5 g (1.32 oz)

b.

Installed balance weight in the position.
