the fuel-filler cap is installed and closed tightly, and that the vehicle has at least 3 gallons (11.4 liters) of fuel in the fuel tank. After a few driving trips, the light should turn off if no other potential emission control system malfunction exists. 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. 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. See "Driving the vehicle" in the "Starting and driving" section of this manual. Turn signal/hazard indicator lights The appropriate light flashes when the turn signal switch is activated. Both lights flash when the hazard switch is turned on. 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. AUDIBLE REMINDERS Brake pad wear warning The disc brake pads have audible wear warnings. When a disc brake pad requires replacement, it makes a high pitched scraping sound when the vehicle is in motion, whether or not the brake pedal is depressed. Have the brakes checked as soon as possible if the warning sound is heard. Instruments and controls 2-13
