Engine oil pressure warning
light
This light warns of low engine oil pressure.
If the light flickers or comes on during
normal driving, pull off the road in a safe
area, stop the engine immediatelyand call
an INFINITI retailer or other authorized
repair shop.
The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level. (See
“Engine oil” (P.8-10).)
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not covered
by warranty. Turn off the engine as soon as
it is safe to do so.
Intelligent Cruise Control (ICC)
system warning light (orange; if so
equipped)
This light comes on if there is a malfunc-
tion in the Intelligent Cruise Control (ICC) system.
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, resume driving and set
the ICC system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the
vehicle is still driveable under normal
conditions, have the vehicle checked at
an INFINITI retailer.
Intelligent Key warning light
After the ignition switch is pushed to the
ON position, this light comes on for about
2 seconds and then turns off.
This light warns of a malfunction with the
Intelligent Key system.
If the light comes on while the engine is
stopped, it may be impossible to start the
engine. If the light comes on while the
engine is running, you can drive the
vehicle. However in these cases, contact
an INFINITI retailer for repair as soon as
possible.
Low tire pressure warning
light
Your vehicle is equipped with a Tire
Pressure Monitoring System (TPMS) that
monitors the tire pressure of all tires
except the spare.
The low tire pressure warning light warns
of low tire pressure or indicates that the
TPMS is not functioning properly.
After the ignition switch is pushed ON, this
light illuminates for about 1 second and
turns off.
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
A CHECK TIRE PRESSURE warning also
appears in the dot matrix liquid crystal
display.
When the low tire pressure warning light
illuminates, you should stop and adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire and
Loading Information label. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is
adjusted. After the tire is inflated to the
recommended pressure, the vehicle must
be driven at speeds above 16 MPH (25

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Run the engine until it reaches operat- ing temperature.
3. Turn off the engine. Wait more than 15
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 within the
range
*1. If the oil level is below*2,
remove the oil filler cap and pour recommended oil through the opening.
Do not overfill
*3.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the break-
in period, depending on the severity of
operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by the war-
ranty.
CHANGING ENGINE OIL AND FILTER
Vehicle set-up
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operat- ing temperature.
3. Turn the engine off and wait more than 15 minutes.
4. Raise and support the vehicle using a suitable floor jack and safety jack
stands.
.Place the safety jack stands underthe vehicle jack-up points.
.A suitable adapter should be at-tached to the jack stand saddle.
5. Remove the plastic engine undercover. a. Remove the small plastic clips at the center of the undercover.
b. Then remove the bolts that hold the undercover in place.
CAUTION
Make sure the correct lifting and support
points are used to avoid vehicle damage.

Engine oil and filter
1. Place a large drain pan under the drainplug.
2. Remove the oil filler cap.
3. Remove the drain plug
*1with a
wrench and completely drain the oil.
CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
.Waste oil must be disposed of
properly.
.Check your local regulations.
(Perform steps 4 to 7 only when the
engine oil filter change is needed.)
4. Loosen the oil filter
*2with an oil filter
wrench. Remove the oil filter by turning
it by hand.
5. Wipe the engine oil filter mounting surface with a clean rag.
CAUTION
Be sure to remove any old rubber gasket
remaining on the mounting surface of the
engine. Failure to do so could lead to engine
damage.
6. Coat the gasket on the new filter withclean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten
additionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(14.7 to 20.5 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the
drain plug with a wrench. Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill the engine with the recommended oil through the oil filler opening, and
install the oil filler cap securely.
See “Capacities and recommended
fuel/lubricants” (P.9-2) for drain and
refill capacity. The drain and refill
capacity depends on the oil tempera-
ture and drain time. Use these specifi-
cations for reference only. Always use
the dipstick 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.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
