SECURITY SYSTEMS (if so equipped) If the battery is removed or discharged, the vehicle dynamic control system is disabled and the VDC indicator light will not turn off after 2 seconds when the ignition switch is turned to the ON position. To reset the system, you must perform the reset procedure. Refer to "Vehicle dynamic control (VDC) system" in the "Starting and driving" section of this manual. If the light does not go off after performing the reset procedure, have the traction control system checked by a NISSAN dealer. While the vehicle dynamic control system is operating, you might feel slight vibration or hear the system working when starting the vehicle or accelerating, but this is normal. The VDC system will be disabled and the VDC light will illuminate when the electronic locking rear differential (E-lock) system switch (if so equipped) is turned on and the E-lock system is engaged. If the E-lock system disengages or the switch is turned off, the VDC system will be enabled and the VDC light will turn off. 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. Key reminder chime A chime sounds if the driver's door is opened while the key is left in the ignition switch. Remove the key and take it with you when leaving the vehicle. LIC0372 Light reminder chime With the ignition switch in the OFF position, a chime sounds when the driver's door is opened if the headlights or parking lights are on. Turn the headlight control switch off before leaving the vehicle. Your vehicle may have two types of security systems: ● Vehicle security system (if so equipped) ● NISSAN Vehicle Immobilizer System (if so equipped) VEHICLE SECURITY SYSTEM (if so equipped) The vehicle security system provides visual and audible alarm signals if someone opens the doors when the system is armed. It is not, however, a motion detection type system that activates when a vehicle is moved or when a vibration occurs. 2-18 Instruments and controls
