maintenance reset NISSAN ALTIMA 1999 L30 / 2.G Owners Manual

Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the ``ready
condition'' for an Inspection/Maintenance
(I/M) test of the emission control system.
The vehicle is set to the ``ready condition''
when it is driven through certain driving
patterns. Usually, the ready condition can be
obtained by ordinary usage of the vehicle.
If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a ``not ready'' condition.
Before taking the I/M test, drive the vehicle
through the following pattern to set the ve-
hicle to the ready condition. If you cannot or
do not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.

ner according to traffic conditions and
