Nissan Sentra B18 (2020-2025) Owner's Manual: Push-button ignition switch

WARNING

Do not operate the push-button ignition switch while driving the Nissan Sentra except in a true emergency. The engine will stop if the ignition switch is pressed three consecutive times in quick succession or if it is pressed and held for more than 2 seconds. If the engine stops while the vehicle is in motion, this may result in loss of control, a collision, and serious personal injury.

When the ignition switch is pressed without depressing the brake pedal, the ignition switch position indicator illuminates in the following sequence. Push the center of the switch:

• Once to change to the ON position.
• Two times to change to the OFF position.

The ignition switch will automatically return to the LOCK position when any door is opened or closed while the switch is in the OFF position.

The shift lever can be moved from the P (Park) position only when the ignition switch is in the ON position and the brake pedal is depressed.

If the vehicle battery is discharged, the ignition switch cannot be moved from the LOCK position.

Various indicators and warning messages related to ignition switch operation are displayed in the meter of the Nissan Sentra.

Operating range

The Intelligent Key functions of the Nissan Sentra can be used only when the Intelligent Key is within the specified operating range.

When the Intelligent Key battery is nearly discharged or when strong radio waves are present near the vehicle, the operating range of the Intelligent Key system becomes reduced and may not function correctly.

If the Intelligent Key is within the operating range, it is possible for anyone, even a person not carrying the Intelligent Key, to press the ignition switch and start the engine.

The operating range for engine start is inside the passenger compartment of the Nissan Sentra.

• The luggage area is not included in the normal operating range; however, the Intelligent Key may still function in some cases.
• If the Intelligent Key is placed on the instrument panel, inside the glove box, storage bin, or door pocket, it may not function properly.
• If the Intelligent Key is placed near a door or window outside the vehicle, the Intelligent Key may function unintentionally.

Push-button ignition switch positions

LOCK (Normal parking position)

The ignition switch can only be locked in this position.

The ignition switch will be unlocked when it is pressed to the ON position while carrying the Intelligent Key.

The ignition switch will lock automatically when any door is opened or closed with the ignition switched off.

ON (Normal operating position)

In this position, the ignition system and all electrical accessories of the Nissan Sentra are activated, even though the engine is not running.

The ON position includes a battery saver feature. If the vehicle is not running, the ignition switch will automatically change to the OFF position after a certain period to help prevent battery discharge.

CAUTION

Do not leave the Nissan Sentra with the ignition switch in the AUTO ACC or ON position for an extended period when the engine is not running. Doing so may discharge the vehicle battery.

OFF

The ignition switch is in the OFF position when the engine is turned off using the push-button ignition switch. No indicator lights will be illuminated on the switch.

AUTO ACC:

Ensure the Nissan Sentra is in the P (Park) position and that the Intelligent Key is with you. Move the ignition switch from the ON position to the OFF position.

The vehicle will enter AUTO ACC mode. In this mode, the audio system and certain electronic accessories remain operational for a limited time under the following conditions:

• The driver’s door has not been opened.
• The preset time period has not expired.

Emergency engine shut off

To shut off the engine of the Nissan Sentra in an emergency situation while driving, perform one of the following actions:

• Quickly press the ignition switch three times within less than 1.5 seconds, or
• Press and hold the ignition switch for more than 2 seconds.

NISSAN Intelligent Key battery discharge

If the battery of the NISSAN Intelligent Key is discharged, or if environmental conditions interfere with Intelligent Key operation, start the Nissan Sentra engine using the following procedure:

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

2. Firmly apply the foot brake to ensure the Nissan Sentra remains stationary.

3. Touch the ignition switch with the Intelligent Key as illustrated. A confirmation chime will sound to indicate that the system has detected the Intelligent Key.

After step 3 is completed, if the ignition switch is pressed without depressing the brake pedal, the ignition switch position will change to the ON position, allowing electrical systems of the Nissan Sentra to activate.

4. Within 10 seconds after the chime sounds, push the ignition switch while fully depressing the brake pedal. The engine of the Nissan Sentra will then start normally.

NOTE:

• When the ignition switch is moved to the ON position or the engine is started using the procedure above, the Intelligent Key battery discharge indicator may appear in the vehicle information display even when the Intelligent Key is inside the Nissan Sentra. This condition does not indicate a malfunction.

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

• If the Intelligent Key battery discharge indicator appears repeatedly, replace the Intelligent Key battery as soon as possible to ensure reliable operation.

NISSAN Vehicle Immobilizer System

The NISSAN Vehicle Immobilizer System is designed to enhance security and will not allow the engine of the Nissan Sentra to start unless a properly registered Intelligent Key is used.

If the engine does not start with a registered key, for example due to signal interference from another registered key, an automated toll device, or an automatic payment device located on the same key ring, restart the engine by performing the following steps:

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

2. Move the ignition switch to the OFF or LOCK position and wait approximately 10 seconds.

3. Repeat steps 1 and 2.

4. Restart the engine while holding the device that may have caused interference away from the registered Intelligent Key.

If the no-start condition occurs again, NISSAN recommends keeping the registered Intelligent Key on a separate key ring to minimize potential interference from other electronic devices.

Before starting the engine

• Ensure the area surrounding the Nissan Sentra is clear of people, animals, and obstacles.
• Check fluid levels such as engine oil, engine coolant, brake fluid, clutch fluid (if so equipped), and windshield washer fluid regularly, ideally at each refueling stop.
• Confirm that all windows, mirrors, and exterior lights are clean and unobstructed.
• Visually inspect the tires for overall condition and appearance, and verify that all tires are inflated to the recommended pressure.
• Make sure all doors are securely closed and locked.
• Adjust the seating position and head restraints/headrests for proper comfort and support.
• Adjust both the interior and exterior mirrors for optimal visibility.
• Fasten your seat belt and ensure that all passengers do the same before driving the Nissan Sentra.
• Check the operation of all warning lights when the ignition switch is placed in the ON position.
