The following warning messages and indicator notifications may appear in the vehicle information display of the Nissan Sentra, helping the driver quickly identify system status, reminders, or potential issues that may require attention.

Engine start operation for Intelligent Key system (if I-Key battery level is low)

This indicator appears when the battery level of the Intelligent Key is low and when the Intelligent Key system and the Nissan Sentra are not communicating normally.

If this message appears, touch the ignition switch with the Intelligent Key while depressing the brake pedal to start the engine. This procedure allows continued operation of the Nissan Sentra even when the key battery is weak.

  Key Battery Low

This indicator appears when the Intelligent Key battery is running out of power.

If this indicator is displayed, replace the Intelligent Key battery with a new one as soon as possible to maintain reliable operation of the Nissan Sentra keyless entry and start systems.

Key ID Incorrect

This warning appears when the ignition switch is moved from the OFF position and the Intelligent Key is not recognized by the system. The engine cannot be started with an unregistered or incompatible key.

Key System Error: See Owner's Manual

After the ignition switch is placed in the ON position, this warning may appear briefly and then turn off.

The Key System Error message indicates a possible malfunction within the Intelligent Key system of the Nissan Sentra.

If the warning appears while the engine is stopped, starting the engine may not be possible.

If the warning appears while the engine is running, you may continue driving the vehicle. However, in this situation, have the system inspected as soon as possible. It is recommended that you visit an authorized NISSAN dealer for professional diagnosis and service.

No Key Detected

This warning appears when the Intelligent Key is left outside the Nissan Sentra while the ignition switch is in the ON position. Confirm that the Intelligent Key is located inside the vehicle.

Rear Door Alert is activated

When this system is enabled, the message appears while the Rear Door Alert system is active and serves as a reminder for the driver to check the rear seat area.

• Using the steering wheel switch, the driver can select “Dismiss Message” to clear the display for a short period of time. If no selection is made, the message will automatically turn off after a brief interval. If the message remains visible, it does not indicate a malfunction.

• Using the steering wheel switch, the driver can select “Disable Alert” to deactivate the selected alert for the remainder of the current trip in the Nissan Sentra.

WARNING

Selecting “Dismiss Message” during a stop within a trip temporarily dismisses the alert for that specific stop without turning the system off.

NOTE:

This system remains disabled until the driver enables it through the vehicle information display settings.

Check Rear Seat For All Articles

When the system is enabled, this message appears after the vehicle comes to a complete stop, is shifted from the D (Drive) position to the P (Park) position, and the driver exits the Nissan Sentra. After a short delay and an audible alert, the message reminds the driver to check the rear seat for any passengers or items left behind.

Transmission Shift Position indicator

This indicator shows the current transmission shift position, allowing the driver to easily confirm the selected gear while operating the Nissan Sentra.

CVT hot Power reduced

The Continuously Variable Transmission (CVT) in the Nissan Sentra is equipped with a high fluid temperature protection mode. If the transmission fluid temperature becomes excessively high, such as when climbing steep grades in hot weather with heavy loads, engine power and, in some cases, vehicle speed will be automatically reduced to help prevent transmission damage.

WARNING

When the high fluid temperature protection mode is activated, vehicle speed may gradually decrease and could become lower than surrounding traffic. This situation may increase the risk of a collision. Drive with extra caution. If necessary, pull over to a safe location and allow the transmission to cool and return to normal operation, or have the vehicle inspected and repaired if required.

CVT Malfunction Service now

This warning appears when a malfunction is detected in the CVT system. If this message is displayed, have the Nissan Sentra inspected as soon as possible. It is recommended that you visit an authorized NISSAN dealer for professional service.

Engine hot Power reduced

The engine in the Nissan Sentra is also equipped with a high temperature protection mode. If engine temperature becomes too high, such as during prolonged uphill driving in high ambient temperatures with heavy loads, engine power and, under certain conditions, vehicle speed will be automatically reduced to minimize the risk of engine damage.

Vehicle speed can still be controlled using the accelerator pedal, but overall engine output and vehicle speed may be limited until temperatures return to a normal range.

WARNING

When the high fluid temperature protection mode is activated, vehicle speed may be gradually reduced. The reduced speed may be lower than surrounding traffic, which could increase the risk of a collision. Exercise extra caution when driving the Nissan Sentra under these conditions. If necessary, pull over to a safe location and allow the engine to return to normal operating temperature, or have the vehicle inspected and repaired if required.

Engine Malfunction: Power Reduced Service now

This message indicates the remaining distance until the next engine oil change. It is displayed when the distance to the oil change is less than 62 miles (100 km), helping Nissan Sentra owners plan timely maintenance.

Engine Stalled: Stop safely

This message appears approximately 30 seconds before the vehicle is automatically shut down due to an abnormally high exhaust temperature.

When this occurs, the Malfunction Indicator Light (MIL) and the red malfunction warning light will illuminate.

Have the system checked immediately. It is strongly recommended that you visit a NISSAN dealer without delay to prevent further damage to your Nissan Sentra.
