If this indicator light comes on steady for 20 seconds and then blinks for 10 seconds when the engine is not running, it indicates that the vehicle is not ready for an emission control system inspection/maintenance test. See "Readiness for inspection/maintenance (I/M) test" in the "Technical and consumer information" section of this manual. Operation The malfunction indicator light will come on in one of two ways: ● Malfunction indicator light 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 light should turn off after a few driving trips. If the light does not turn off after a few driving trips, have the vehicle inspected by a NISSAN dealer. You do not need to have your vehicle towed to the dealer. ● Malfunction indicator light 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 light 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. See "Driving the vehicle" in the "Starting and driving" section of this manual. Security indicator light This light blinks whenever the ignition switch is in the LOCK, OFF or ACC position. This function indicates the security system equipped on the vehicle is operational. For additional information, see "Security systems" later in this section. CAUTION Continued vehicle operation without having the emission control system checked and repaired as necessary could lead to poor driveability, reduced fuel economy, and possible damage to the emission control system. Slip indicator light for models with ABLS (if so equipped) This indicator light comes on if the active brake limited slip is activated. If activated, the system will apply braking to the slipping drive wheel(s), giving the non-slipping wheel(s) more traction. Overdrive off indicator light (automatic transmission models only) This light comes on when the overdrive function is OFF. The automatic transmission overdrive function is controlled by the overdrive switch. Slip indicator light for models with VDC (if so equipped) This indicator light will blink when the traction control system is limiting wheel spin. Slippery road conditions may exist if the slip indicator blinks on. If this happens, adjust your driving accordingly. The slip indicator light also comes on when you turn the ignition key to the ON position. The light will turn off after about 2 seconds if the system is 2-16 Instruments and controls
