Nissan Altima (L34) 2019-2024 Owners Manual: NISSAN Intelligent Key battery discharge

If the battery of the NISSAN Intelligent Key is discharged or environmental conditions interfere with the Intelligent Key operation, start the engine according to the following procedure:

1. Place the shift lever in the P (Park) position.

2. Firmly apply the foot brake.

3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime will sound.)

After step 3 is performed, when the ignition switch is pushed without depressing the brake pedal, the ignition switch position will change to the ON position.

4. Push the ignition switch while depressing the brake pedal within 10 seconds after the chime sounds. The engine will start.

NOTE:

• When the ignition switch is pushed to the ON position or the engine is started by the above procedure, the Intelligent Key battery discharge indicator appears in the vehicle information display even when the Intelligent Key is inside the vehicle. This is not a malfunction.

  To turn off the Intelligent Key battery discharge indicator, touch the ignition switch with the Intelligent Key again.

• If the Intelligent Key battery discharge indicator appears, replace the battery as soon as possible. For additional information, see "Battery replacement".

NISSAN Vehicle Immobilizer System

The NISSAN Vehicle Immobilizer System will not allow the engine to start without the use of the registered key.

If the engine fails to start using a registered key (for example, when interference is caused by another registered key, an automated toll road device or automatic payment device on the key ring), restart the engine using the following procedure:

1. Leave the ignition switch in the ON position for approximately 5 seconds.

2. Place the ignition switch in the OFF or LOCK position, and wait approximately 10 seconds.

3. Repeat steps 1 and 2.

4. Restart the engine while holding the device (which may have caused the interference) separate from the registered key.

If the no start condition re-occurs, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices.

Before starting the engine

• Make sure the area around the vehicle is clear.
• Check fluid levels such as engine oil, coolant, brake fluid, and windshield-washer fluid as frequently as possible, or at least whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper inflation.
• Lock all doors.
• Position seat and adjust headrests/head restraints.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is pushed to the ON position. For additional information, see "Warning lights, indicator lights and audible reminders".
