Engine oil

WARNING

Hot oil.
Oil can contain combustion residues which are harmful to health.

Risk of injury and poisoning!

• Wear protective clothing, gloves, and goggles / safety mask.
• Avoid contact with skin.
• Do not inhale oil vapor.

WARNING

Oils/oil vapors are combustible/explosive.

Risk of fire and explosion!

• Avoid open flames, electric sparks and ignition sources.
• Do not smoke.

Engine oil extraction

Open shut-off valve(s) in extraction line on engine and waste-oil tank.

Extract all oil from oil pan using the electric pump.

Close shut-off valve(s).

Filling with new engine oil

Determine oil change quantity for fuel optimized (→ Page 24) or emissions-optimized (→ Page 28) en-
gine version.

Use electric pump to fill engine with oil from new-oil tank until the "max." mark on the oil dipstick is
reached.

Check engine oil level (→ Page 174).
