Features of the all-wheel drive system

The heart of cross-country ability Nissan X-Trail T31 is an intelligent system All Mode 4x4-i, which automatically distributes torque between the axles depending on the driving situation. In normal driving mode, the car operates as a front-wheel drive, which saves fuel and reduces wear on components. However, when the front axle slips, the clutch instantly transfers up to 50% of the power to the rear wheels, ensuring trajectory stability.

The driver has three main switching modes available, which are selected through a special selector on the center console. Mode Auto designed for everyday driving on asphalt and light off-road, where the system itself decides when to engage the rear axle. Mode Lock rigidly locks the clutch, distributing torque 50/50, which is critical when driving through deep snow, mud or sand at speeds up to 80 km/h.

It is important to understand that the mode 4WD High not intended for driving on dry asphalt with a high coefficient of adhesion, as this can lead to overheating of the clutch and its failure. When the lock is turned on, the corresponding indicator on the instrument panel lights up, signaling the transition to hard mode.

There are a number of limitations that must be taken into account when using all-wheel drive in extreme conditions. For example, when driving on steep climbs or descents, you should avoid sudden changes in the gas pedal, so as not to provoke slipping and activation of the stabilization system.

• 🚗 Use the mode Lock only at speeds below 80 km/h and turn it off when returning to dry asphalt.
• ⚙️ Regularly check the condition of the rear axle coupling, as it is a consumable item.
• ❄️ During the winter period, switching modes should only be done while the car is stationary with the brake on.

Operation of CVT transmission

Continuously variable transmission CVT (Continuously Variable Transmission) is one of the most vulnerable components in Nissan X-Trail T31. It provides smooth running and high fuel efficiency, but requires strict adherence to maintenance rules. The main enemy of the variator is overheating and the use of low-quality fluid, which loses its properties at high temperatures.

When operating a vehicle with this type of transmission, it is necessary to avoid sudden starts and extreme engine braking, as this creates enormous loads on the cones and belt. The engine must operate in the optimal speed range, and the control system must be able to smoothly change the gear ratio. Any jerks or vibrations during acceleration are a signal of possible problems.

Particular attention should be paid to the level and quality of oil in the variator. The manufacturer recommends replacing the fluid every 60 thousand kilometers, but in practice, given the operating conditions in Russia, it is better to reduce the interval to 40-50 thousand. Using original liquid Nissan NS-2 is a prerequisite for a long life of the unit.

In the cold season, the variator requires mandatory warming up before driving. The oil in the box must reach operating temperature to ensure sufficient hydraulic pressure and lubrication of all rubbing pairs. Ignoring this rule leads to premature wear of bearings and cones.

• 🔧 Change the oil in the variator at least once every 40,000 km, using only original fluid.
• 🌡️ In winter, warm up the transmission for 5-10 minutes before starting active driving.
• 🛑 Avoid towing a trailer heavier than the permitted limit, as this will overload the variator belt.
