9-6Maintenance and schedules
Brake pads and rotors:
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/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:
Rotate tires at the specified interval. When
rotating tires, check for damage and uneven
wear. Replace if necessary.
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)/96 months. For most people,
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)/96
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. .
Operating in hot weather in stop-and-go
“rush hour” traffic.
. Extensive idling and/or low speed driving
for long distances, such as police, taxi or
door-to-door delivery use.
. Driving in dusty conditions.
. Driving on rough, muddy or salt spread
roads.
. Towing a trailer, using a camper or car-
top carrier.
If your vehicle is mainly operated under the
severe conditions, follow the severe main-
tenance intervals shown in the maintenance
schedule.
