Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” 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, check the vehicle’s inspection/
maintenance test readiness condition. Turn the
ignition switch ON without starting the engine. If
the Malfunction Indicator Light (MIL) comes on
steady for 20 seconds and then blinks for 10
seconds , the I/M test condition is “not ready”. If
the MIL does not blink after 20 seconds, the I/M
test condition is “ready”. If the MIL indicates the
vehicle is in a “not ready” condition, drive the
vehicle through the following pattern to set the
vehicle to the ready condition. If you cannot or do
not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.
WARNING

prudent manner according to traffic con-
ditions and obey all traffic laws.
