The engine oil pressure warning light is not
designed to indicate a low oil level.Use the
dipstick to check the oil level. For additional
information, see “Engine oil” (P. 8-6).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause seri-
ous damage to the engine almost immedi-
ately. Such damage is not covered by war-
ranty. Turn off the engine as soon as it is
safe to do so.
Master warning light
When the ignition switch is in the ON posi-
tion, the master warning light illuminates if
any of the following (if so equipped) are dis-
played on the vehicle information display:
• Parking brake warning
• Door warning (when vehicle is moving)
• Shift position warning
• Low battery warning
• Handle Release warning
For additional information, see “Vehicle in-
formation display” (P. 2-19).
Seat belt warning light and
chime
The light and chime remind you to fasten your
seat belts. The light illuminates whenever the
ignition switch is placed in the ON position
and remains illuminated until the driver's seat
belt is fastened. At the same time, the chime
sounds for about 6 seconds unless the driv-
er's seat belt is securely fastened.
The seat belt warning light may also illumi-
nate if the front passenger's seat belt is not
fastened when the front passenger's seat is
occupied. For 7 seconds after the ignition
switch is placed in the ON position, the sys-
tem does not activate the warning light for
the front passenger.
The 2nd row seats may be also equipped with
a seat belt warning light.
For additional information, see “Seat belts”
(P. 1-11).
Security indicator light
This light blinks when the ignition switch is
placed in the OFF or LOCK position.
The blinking security indicator light indicates
that the security systems equipped on the
vehicle are operational. For additional information, see “Security sys-
tems” (P. 2-29).
Supplemental air bag
warning light
When the ignition switch is placed in the ON
position, the supplemental air bag warning
light illuminates for about 7 seconds and then
turns off. This means the system is
operational.
If any of the following conditions occur, the
front air bag, side air bag, curtain air bag, and
pretensioner seat belt systems need
servicing:
• The supplemental air bag warning light re-
mains on after approximately 7 seconds.
• The supplemental air bag warning light flashes intermittently.
• The supplemental air bag warning light does not come on at all.
It is recommended that you visit an INFINITI
retailer for these services.
Unless checked and repaired, the supplemen-
tal restraint system (air bag system) and/or
the pretensioners may not function properly.
For additional information, see “Supplemen-
tal Restraint System (SRS)” (P. 1-41).

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check the
oil level. It should be between the H (High)
and L (Low) marksOB. This is the normal
operating oil level range. If the oil level is
below the L (Low) mark
OA, remove the oil
filler cap and pour recommended oil
through the opening. Do not fill oil level
above H (High) mark
OC.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil main-
tenance intervals or during the break-in pe-
riod, depending on the severity of operating
conditions.
CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
CHANGING ENGINE OIL AND OIL
FILTER
For additional information on engine oil and
oil filter change, refer to the instructions out-
lined in this section.
Vehicle set-up
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn the engine off and wait for 15 minutes.
4. Raise and support the vehicle using a suit- able floor jack and safety jack stands.
• Place the safety jack stands under the ve- hicle jack-up points.
• A suitable adapter should be attached to the jack stand saddle.LDI3158LDI0371

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.
