After a few driving trips, the lamp should turn off if no other potential emission control system malfunction exists. Operation The malfunction indicator lamp will come on in one of two ways: ● Malfunction indicator lamp on steady - An emission control system malfunction has been detected. Check the fuel filler cap. If the fuel filler cap is loose or missing, tighten or install the cap and continue to drive the vehicle. The lamp should turn off after a few driving trips.

You do not need to have your vehicle towed to the dealer. ● Malfunction indicator lamp blinking - An engine misfire has been detected which may damage the emission control system. To reduce or avoid emission control system damage: - do not drive at speeds above 45 MPH (72 km/h). - avoid hard acceleration or deceleration. - avoid steep uphill grades. - if possible, reduce the amount of cargo being hauled or towed. The malfunction indicator lamp may stop blinking and come on steady. Have the vehicle inspected by a NISSAN dealer. You do not need to have your vehicle towed to the dealer.
