darkness of the surroundings. The other exterior lights and instrument panel
lights automatically turn on or off.

A buzzer sounds when the engine switch is turned OFF and the driver's door
is opened with the key removed from the engine switch while the lights are
turned on. Vehicles with smart key system
A buzzer sounds when the “ENGINE START STOP” switch is turned OFF or
to ACCESSORY mode and the driver's door is opened while the lights are

■
When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
