a. Remove the oil filler cap and wipe the dipstick clean.
b. Check the oil level by inserting the dipstick in the filler hole
without screwing it in.
c. If the oil level is low, fill to the upper limit of the oil filler neck with
the recommended oil.
Running the engine with insufficient oil can cause serious engine
damage.
The Oil Alert system will automatically stop the engine before the oil
level falls below the safe limit. However, to avoid the inconvenience of
an unexpected shutdown, it is still advisable to visually inspect the oil
level regularly.
