ENGINE OIL

Checking the Engine Oil Level

Engine oil is used for lubrication and

during driving the vehicle.

Regularly check and manage the oil level

using the following procedure.

1. Follow all of the oil manufacturer’s

precautions.

2. Be sure the vehicle is on the level

5. Pull the dipstick out, wipe it clean, and

re-insert it fully.

the engine is cool.

If the coolant level is low, add the

selected anti-freeze according to the

proper coolant mix ratio to bring the level

to the MAX mark, but do not overfill. If

frequent additions are required, see an
