Normal Operating Condition Nissan Pathfinder Fifth generation

Description

LED HEADLAMP

• LED brightness and color may slightly change until the temperature becomes stable. This is not a malfunction.

• Illumination time lag may occur between right and left. This is not a malfunction.

• Brightness may be reduced due to aged deterioration of LED.

AUTO LIGHT SYSTEM

The headlamp may not be turned ON/OFF immediately after passing a dark area or bright area (short tunnel, sky bridge, shadowed area etc.) while using the auto light system. This causes the control difference. This is normal.

HIGH BEAM ASSIST SYSTEM

When driving while using the high beam assist system, the headlamp beam may not switch or the beam switching timing may vary according to the ambient environment (the condition of the Nissan Pathfinder vehicle ahead, the condition of the road, the position of the vehicle, etc.).This is due to control differences and is not a malfunction.
