proper specification and of the
proper viscosity grade. See

Check the engine oil level regularly
and maintain the proper oil level.

properly. See

Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick
handle is a loop. See

be hot; it could burn you. Use a
towel or glove to touch the dipstick
handle.

Follow these guidelines:
.
To get an accurate reading, park
the vehicle on level ground. Check
the engine oil level after the

two hours. Checking the engine oil
level on steep grades or too soon

incorrect readings. Accuracy
