2.5.10 Checking the Oil Level

Ensure that the vehicle is parked on level ground
before checking the oil level. Wait five minutes
after shutting off the engine and then proceed
with checking the oil.
CAUTION
DO NOT let the oil level fall below the marking
on the dipstick. DO NOT overfills so the level
is above the upper marking on the dipstick.
This could lead to excessive oil temperature
and/or poor crankcase breather performance.
Add oil through the oil filler pipe as required in
order to maintain level within the safe range.
