2021 INFINITI QX50 child lock

CAUTION
Be careful not to burn yourself, as the en-
gine oil is hot.
WARNING
• Prolonged and repeated contact with
used engine oil may cause skin cancer.
• Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
• Keep used engine oil out of reach of
children.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Remove the oil filter by turning it by hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the en-
gine. Failure to do so could lead to an oil
leak and engine damage. •
The dipstick must be inserted in place to
prevent oil spillage from the dipstick hole
when filling the engine with oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten addi-
tionally more than 2/3 turn.
Oil filter tightening torque: 14.7 to 20.6 N·m (11 to 15 ft-lb)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench. Do not use excessive
force.
Drain plug tightening torque: 29.4 to 39.2 N·m (22 to 29 ft-lb)
9. Refill the engine with the recommended oil through the oil filler opening, and install
the oil filler cap securely.
For additional information about drain and
refill capacity, see “Recommended fluids/
lubricants and capacities” (P. 10-2). The drain
and refill capacity depends on the oil tem-
perature and drain time. Use these specifica-
tions for reference only. Always use the dip-
stick to determine the proper amount of oil in
the engine. 10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add engine
oil if necessary.
After the operation
1. Reinstall engine protectors in reverse or-der of removal.
2. Lower the vehicle carefully to the ground.
3. Reset the oil control system. For addi- tional information, see “Vehicle informa-
tion display” (P. 2-19)
• Dispose of waste oil and filter properly.
• Check your local regulations.
