GENERAL DESCRIPTION
CC:DTC P0442 EVAPORATIVE EMISSION CONTROL SYSTEM LEAK DETECT-
ED (SMALL LEAK)
1. OUTLINE OF DIAGNOSIS
Check if there is a leakage in fuel system or not, and perform the function diagnosis of valve.
In this system diagnosis, check for leakage and valve function is conducted by changing the fuel tank pres-
sure and monitoring the pressure change using the fuel tank pressure sensor.
When in 0.04 inch diagnosis, perform in the order of mode Z → mode A → mode B → mode C and mode D;
When in 0.02 inch diagnosis, perform in the order of mode A → mode B → mode C → mode D and mode E.

Engine Oil
LUBRICATION
3. Engine Oil
A: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and properly
orientated.
4) Remove it again and check the reading. If the
engine oil level is below “L” line, add oil to bring the
level up to “F” line.
5) After turning off the engine, wait a few minutes
for the oil to return to the oil pan before checking
the level.
NOTE:
To prevent overfilling of engine oil, do not add oil
above “F” line when the engine is cold.
B: REPLACEMENT
1) Open the engine oil filler cap for quick draining of
engine oil.
2) Lift-up the vehicle.
3) Drain engine oil by loosening the engine oil drain
plug.
NOTE:
Prepare the container for draining of engine oil.
4) Tighten the engine oil drain plug after draining
engine oil.
NOTE:
Use a new drain plug gasket.
Tightening torque:
44 N·m (4.5 kgf-m, 33 ft-lb)
5) Using engine oil of proper quality and viscosity,
fill engine oil through the oil filler duct to the upper
level on level gauge. Make sure that the vehicle is
parked on a level surface when checking oil level.
Recommended oil:
Refer to “SPECIFICATION” for the recom-
mended oil. CATION, General Description.>
Engine oil capacity
Refer to “SPECIFICATION” for the engine oil
capacity. TION, General Description.>
6) Close the engine oil filler cap.
