ENGINE MAINTENANCE

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.

PCV VALVE VENTILATION HOSE

1.

Check hoses and hose connections for leaks.

2.

Disconnect all hoses and clean with compressed air. If any hose
cannot be freed of obstructions, replace.

EVAP VAPOR LINES

EVAP VAPOR LINES : Inspection

INFOID:0000000010005029

1.

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

EC-329, "Component Inspection"

.

2.

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

EC-534, "Inspection"

EXHAUST SYSTEM

EXHAUST SYSTEM : Inspection

INFOID:0000000009722397

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:0000000009722398

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-152, "Changing"

.

CVT FLUID : Changing

INFOID:0000000010005031

CAUTION:

Replace an 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-171, "Exploded View"

.

5.

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

CAUTION:

• Use only recommended fluid. Never mix with other fluid.
• Using CVT fluid other than recommended 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-38,

"CONSULT Function"

.

6.

With the engine warmed up, drive the vehicle in an urban area.

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.
