NOTE:
HMaintenance items with ªHº should be performed more frequently according to ªMaintenance Under Severe Driving Con-
ditionsº.
(1) Use Nissan genuine engine coolant, or equivalent in its quality, in order to avoid possible aluminum corrosion within the
engine cooling system caused by the use of non-genuine engine coolant. After first replacement, replace every 40,000 km (24,
000 miles) or 24 months.
(2) Maintenance-free item. For service procedures, refer to FE section.
*1: Models without three way catalyst
*2: For models with three way catalyst, periodic maintenance is not required. However, if valve noise increases, check valve clearance.
*3: Models with three way catalyst

The following tables show the normal maintenance schedule. Depending upon weather and atmospheric
conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent
maintenance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
