CHECKING INVERTER COOLANT LE-
VEL
Check the coolant level in the reservoir
when the engine and inverter are cold. If
the coolant level is below the MIN level
*B,
add coolant to the MAX level
*A.
If the inverter cooling system frequently
requires coolant, have it checked by an
INFINITI retailer.
CHANGING INVERTER COOLANT
An INFINITI ratailer can change the inverter
coolant. The service procedure can be
found in the INFINITI Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
. To avoid the danger of being scalded,
never change the coolant when the
inverter is hot.
. Never remove the cap when the inverter
is hot. Serious burns could be caused by
high pressure fluid escaping from the
inverter coolant reservoir.
. Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
. Keep coolant out of the reach of children
and pets.
Inverter coolant must be disposed of
properly. Check your local regulations.

CHECKING ENGINE OIL LEVEL
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 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
ENGINE OIL

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 warranty.
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.
.Remove the small plastic clip at the center point of the undercover.
.Then remove the other bolts thathold 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.
4. (Perform steps 4 to 7 only when the engine oil filter change is needed.)
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 with
clean 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 engine with recommended oil and install the oil filler cap securely.
CAUTION
The dipstick must be inserted in place to
prevent oil spillage from the dipstick hole
while filling the engine with oil.
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.
After the operation
1. Install the engine undercover into
position as the following steps.
a. Pull the center of the small plasticclip out.
b. Hold the engine undercover into position.
c. Insert the clip through the under- cover into the hole in the frame, then
push the center of the clip in to lock
the clip in place.
d. Install the other bolts that hold the undercover in place. Be careful not

to strip the bolts or over-tighten
them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.
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.
When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.Use only Genuine NISSAN Matic S ATF.
Do not mix with other fluids.
. Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will
cause deterioration in driveability and
automatic transmission durability, and
may damage the automatic transmis-
sion, which is not covered by the INFINITI
new vehicle limited warranty.
For further brake fluid information, see
“Capacities and recommended fuel/lubri-
cants” (P.9-2) of this manual.
WARNING
.Use only new fluid from a sealed
container. Old, inferior or contaminated
fluid may damage the brake system. The
use of improper fluids can damage the
brake system and affect the vehicle’s
stopping ability.
. Clean the filler cap before removing.
. Brake fluid is poisonous and should be
stored carefully in marked containers out
of the reach of children.
CAUTION
Do not spill the fluid on painted surfaces.
This will damage the paint. If fluid is spilled,
wash the surface with water.

2. Loosen each wheel nut one or two turnsby turning counterclockwise with the
wheel nut wrench. Do not remove the
wheel nuts until the tire is off the
ground.
3. Carefully raise the vehicle until the tire clears the ground. To lift the vehicle,
securely hold the jack lever and rod
with both hands as shown above.
Remove the wheel nuts, and then
remove the tire.
Installing a tire
1. Clean any mud or dirt from the surfacebetween the wheel and hub. 2. Carefully put the tire on and tighten the
wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence as illustrated (
*1,*2,*3,
*4,*5) until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as
illustrated. Lower the vehicle comple-
tely.
WARNING
. Incorrect wheel nuts or improperly tigh-
tened wheel nuts can cause the wheel to
become loose or come off. This could
cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km).
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 80 ft-lb (108 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD pressure.
