Paddle shifter

Manual shift mode

The Nissan Armada offers a manual shift mode that allows the driver to take more direct control of gear selection. While driving in D (Drive), selecting D again activates manual shift mode, providing a more engaging driving experience.

Gear changes in the Nissan Armada manual mode are performed using paddle shifters located on the steering wheel:

When upshifting, pull the right-side paddle shifter (+) A to move to a higher gear.

When downshifting, pull the left-side paddle shifter (−) B to shift into a lower gear.

To exit manual shift mode and return to standard automatic operation, simply shift the Nissan Armada transmission back to D (Drive).

The Nissan Armada transmission system combines advanced electronic control with manual driving flexibility, offering both comfort and performance tailored to different driving conditions.

When operating the Nissan Armada in D (Drive) mode, pulling either paddle shifter allows you to temporarily shift to a higher or lower gear. This feature provides additional control without fully switching to manual mode, enhancing responsiveness when needed.

After a short period of time, the Nissan Armada transmission will automatically return to standard D (Drive) operation. If you prefer to switch back manually, simply pull and hold the paddle shifter for approximately 1.5 seconds.

When the Nissan Armada is in manual shift mode, the currently selected gear range is clearly displayed in the vehicle information display, allowing the driver to monitor and control gear selection with precision.

Gear ranges in the Nissan Armada manual mode can be shifted step-by-step as follows:

9M (9th):

Use this gear in your Nissan Armada for standard highway driving, where optimal fuel efficiency and smooth cruising are required.

8M (8th), 7M (7th), 6M (6th) and 5M (5th):

These ranges are suitable for driving on long inclines or for controlled engine braking when descending extended slopes in the Nissan Armada.

4M (4th), 3M (3rd) and 2M (2nd):

Use these gears when climbing hills or when additional engine braking is needed on downhill roads to maintain safe speed in your Nissan Armada.

1M (1st):

This lowest gear is ideal for steep hill climbs, driving slowly through deep snow, or maximizing engine braking on sharp downhill gradients in the Nissan Armada.

• To maintain fuel efficiency in your Nissan Armada, avoid driving at high speeds for extended periods in gears lower than 7th.
• Pulling the same paddle shifter twice will shift through multiple gear ranges sequentially. However, if performed too quickly, the second shift may not engage correctly.
• In manual mode, the Nissan Armada transmission may refuse a gear selection if it determines that the shift could negatively impact performance or vehicle safety.
• In such cases, the automatic transmission position indicator will blink and an audible chime will alert the driver.
• The Nissan Armada transmission may also automatically upshift if engine speed becomes too high. As the vehicle slows down, it will downshift automatically, eventually returning to 1st gear before coming to a stop.

Accelerator downshift - In D (Drive) position -

For overtaking or climbing hills, fully press the accelerator pedal in your Nissan Armada. This action triggers a downshift to a lower gear, providing increased power depending on vehicle speed.

Fail-safe

The Nissan Armada transmission includes a fail-safe mode designed to protect the system under abnormal operating conditions. When activated, the transmission may remain locked in a specific forward gear depending on the situation.

If the Nissan Armada is driven under extreme conditions, such as excessive wheel spin followed by sudden braking, the fail-safe system may engage.

This protective function may activate even when all electronic systems are functioning normally. In such a case, turn the ignition switch to the OFF position and wait approximately 3 seconds. Then restart the Nissan Armada by switching the ignition back to ON.

The Nissan Armada should return to normal operation after this reset. If normal operation is not restored, have the transmission system inspected and repaired if necessary. It is recommended to visit an authorized Nissan Armada dealer for professional service.

The Nissan Armada transmission system is designed to balance performance, durability, and driver control, ensuring a smooth and reliable driving experience across various road conditions.
