loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section

9-6Maintenance and schedules

To help ensure smooth, safe and economi-
cal driving, NISSAN provides two mainte-
nance schedules that may be used, de-
pending 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 people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 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 conditionsshould be per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed 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 tempera-
tures remaining below freezing.
∙ Operating in hot weather in stop- and-go “rush hour” traffic.
∙ Extensive idling and/or low speed driv- ing 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.
∙ Using a car-top carrier.
OIL CONTROL SYSTEM
Your vehicle is equipped with oil control
system. It calculates engine oil and filter
change intervals based on driving condi-
tions. Driving in the following severe condi-
tions will shorten the engine oil and filter
change interval.
