Description
Description
AUTO LIGHT SYSTEM
The headlamps (both sides) may not turn 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 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 Sentra vehicle ahead, the condition of the road, the position of the vehicle, etc.). This is due to control differences and is not a malfunction.
