8-12Do-it-yourself
When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.It is recommended you use only
Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
. Using automatic transmission fluid
(ATF) other than Genuine NISSAN
Matic S ATF may cause deterioration
in driveability and automatic trans-
mission durability, and may damage
the automatic transmission. Damage
caused by the use of fluid other than
as recommended is not covered by
the INFINITI new vehicle limited
warranty. For further brake fluid information, see
“Capacities and recommended fluids/lubri-
cants” (P.10-2) of this manual.
WARNING
.
Use only new fluid from a sealed
container. Old, inferior or contami-
nated 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 con-
tainers 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.
JVM0053X
Check the fluid level in the reservoir. If the
fluid is below the MIN lineor the brake
warning light comes on, add Genuine
NISSAN Super Heavy Duty Brake Fluid or
equivalent DOT 3fluid up to the MAX line
.
If fluid must be added frequently, the system
should be checked. It is recommended you
visit an INFINITI retailer for this service.

9-6Maintenance and schedules
CHASSIS AND BODY MAINTE-
NANCE
Brake lines and cables:
Visually inspect for proper installation.
Check for chafing, cracks, deterioration,
and signs of leaking. Replace any deterio-
rated or damaged parts immediately.
Brake pads, rotors, drums and linings:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or damaged
parts immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deterioration,
and damage. Tighten connections or replace
parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
replace the filter more frequently.
Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/AWD/RWD)
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:
Check for damage, looseness, and leakage
of oil or grease. Under severe driving condi-
tions, inspect more frequently.Tire rotation:
Tires should be rotated every 5,000 miles
(8,000 km) according to the instructions
under “Explanation of general maintenance
items” (P.9-2). When rotating tires, check for
damage and uneven wear. Replace if neces-
sary.
Transmission fluid/oil, differential oil and
transfer case oil:
Visually inspect for signs of leakage at
specified intervals.
To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 120,000 miles
(192,000 km)/144 months. For most peo-
ple, the odometer reading will indicate when
service is needed. However, if you drive very
little, your vehicle should be serviced at the
regular time intervals shown in the schedule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditions
should be performed
on vehicles that are driven under especially
demanding conditions. Additional mainte-
nance items should be performed if you
primarily operate your vehicle under the
following conditions:
. Repeated short trips of less than 5 miles
(8 km).
. Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.

NOTE:
Maintenance items with “$ ” should be
performed more frequently according to
“Maintenance under severe driving condi-
tions” (P.9-13).
(1) Periodic maintenance is not required.
(2) If using a car-top carrier, or driving on
rough or muddy roads, change (not just inspect) oil at every 20,000 miles (32,000
km) or 24 months.
(3) Refer to “Tire rotation” under “General
maintenance” (P.9-2).
