Nissan Armada 2025-2026 Owner's Manual: Basic information

WARNING

• Never leave children, individuals who require assistance, or pets unattended inside the Nissan Armada. They may unintentionally operate vehicle systems or place themselves and others at risk of injury. In addition, on hot and sunny days, the interior temperature of a parked Nissan Armada can rise rapidly to dangerous levels, potentially causing serious harm or even fatal consequences.
• Always secure cargo properly inside the Nissan Armada to prevent it from shifting during driving. Avoid stacking items higher than the seatbacks, as unsecured objects can become dangerous projectiles during sudden braking or collisions, increasing the risk of injury to occupants.

Exhaust gas (carbon monoxide)

WARNING

• Do not inhale exhaust gases from your Nissan Armada. These gases contain carbon monoxide, a colorless, odorless, and highly toxic substance that can lead to unconsciousness or death.
• If you suspect exhaust fumes are entering the Nissan Armada cabin, immediately open all windows for ventilation and have the vehicle inspected by a qualified technician as soon as possible.
• Never run the engine of your Nissan Armada in enclosed or poorly ventilated areas such as garages.
• Avoid leaving the Nissan Armada engine running for extended periods while the vehicle is stationary.
• Ensure the liftgate of your Nissan Armada remains closed while driving. An open liftgate may allow exhaust gases to enter the passenger compartment. If driving with the liftgate open is unavoidable, follow these precautions:
  1. Open all windows to improve airflow.
  2. Disable air recirculation mode and set the fan speed to the highest level to ensure proper ventilation.
• If electrical wiring or trailer connections pass through the liftgate seal of the Nissan Armada, ensure they are installed according to manufacturer recommendations to prevent carbon monoxide intrusion.
• The exhaust system and vehicle body of your Nissan Armada should be inspected by a qualified mechanic whenever:
  • The vehicle is lifted for maintenance or servicing.
  • You suspect exhaust gases are entering the passenger compartment.
  • You notice unusual sounds coming from the exhaust system.
  • The Nissan Armada has been involved in an accident affecting the rear, underbody, or exhaust system.

Three-way catalyst

The Nissan Armada is equipped with a three-way catalytic converter, an essential component of the emission control system. This device operates at high temperatures to convert harmful exhaust gases into less harmful emissions, helping reduce environmental impact while maintaining optimal engine performance.

To ensure the longevity and efficiency of the Nissan Armada catalytic system, always use the correct fuel type and avoid driving conditions that may cause engine misfire or overheating, as these can damage the catalyst over time.

WARNING

• The exhaust gases and components of the exhaust system in the Nissan Armada can become extremely hot during operation. Always keep people, animals, and any flammable materials at a safe distance from these components to prevent burns or fire hazards.
• Never park or stop your Nissan Armada over combustible materials such as dry grass, leaves, paper, or cloth. These materials can easily ignite due to the high temperatures of the exhaust system, potentially leading to a fire.

CAUTION

• Do not use leaded gasoline in your Nissan Armada. Lead deposits can significantly reduce the efficiency of the three-way catalytic converter, limiting its ability to reduce harmful emissions.
• Keep the Nissan Armada engine properly maintained and tuned. Malfunctions in ignition, fuel injection, or electrical systems may cause excessive fuel to enter the catalytic converter, leading to overheating and possible damage. If you notice engine misfires, reduced performance, or abnormal operation, stop driving and have your Nissan Armada inspected by a qualified technician or authorized dealer as soon as possible.
• Avoid operating your Nissan Armada with a very low fuel level. Running out of fuel may cause engine misfiring, which can damage the catalytic converter.
• Do not rev the engine excessively while it is warming up, as this may place unnecessary stress on engine components.
• Do not attempt to start the Nissan Armada by pushing or towing the vehicle, as this may lead to damage to the emission control system.

Turbocharger system

The Nissan Armada turbocharger system relies on engine oil for both lubrication and cooling of its high-speed rotating components. The turbine operates at extremely high speeds and temperatures, making a consistent and clean oil supply critical for proper performance and durability.

Any sudden interruption in oil flow within the Nissan Armada turbocharger system may result in severe damage or malfunction. Therefore, maintaining proper lubrication is essential for long-term reliability.

To ensure optimal performance and extend the service life of the Nissan Armada turbocharger, always follow the recommended maintenance procedures carefully.

CAUTION

• Change the engine oil in your Nissan Armada at the intervals specified in the "Maintenance and schedules" section to maintain proper lubrication of the turbocharger.
• Always use the recommended engine oil type for your Nissan Armada to ensure compatibility and optimal performance.
• If the Nissan Armada engine has been operating at high speeds for an extended period, allow it to idle for a few minutes before shutting it off. This helps stabilize temperatures and protect the turbocharger components.
• Avoid immediately accelerating the Nissan Armada engine to high RPM right after startup. Allow the engine and oil to reach proper operating conditions first.

By following these guidelines, Nissan Armada owners can ensure long-lasting engine performance, improved efficiency, and reliable operation of both the catalytic converter and turbocharger system.
