EXTERIOR LAMPS

Construction diagram

With the headlamp assembly, the following two types have been provided: Halogen bulbs are equipped for high-beam and low-beam; discharge bulbs are equipped for high-beam and low-beam.
For the halogen type headlamp assembly, the four-headlamp incorporating the headlamp (low-beam), the headlamp (high-beam), the front turn-signal lamp and the position lamp has been adopted.
For discharge type headlamp assembly, the two-headlamp incorporating the headlamp (high-beam / low-beam), the bending lamp, the front turn-signal lamp and the position lamp has been adopted.
Switching of the high-beam and low-beam illumination of the discharge type headlamp is controlled by moving the lightproof board in the projector unit according to the signal from the column switch (lighting switch).
For the low-beam of the headlamp, the headlamp manual levelling system <Vehicles with halogen type headlamp> (Refer to .) and the headlamp automatic levelling system <Vehicles with discharge type headlamp> (Refer to .) have been adopted so that the height adjustment of the optical axis can be performed depending on the vehicle load status.
For the bending lamp, AFS (Refer to .) has been adopted so that the bending lamp, linked with the steering wheel operation, turns ON/OFF its light which beams the cornering direction while vehicle driving.
The front fog lamp with no-cut lens has been adopted for better appearance. <H-line: Standard, M-line: Option>
Two types of the side turn-signal lamp have been established: the one attached to the fender panel and the one integrated into the door mirror.
The rear combination lamps are integrated with the tail/stop lamp and rear turn-signal lamp.
The LED type tail/stop lamps have been adopted for less power consumption and higher safety with illumination speed improvement.
The back-up lamp has been integrated into the tail lamp assembly.
The LED-type high-mounted stop lamp has been integrated into the tailgate spoiler.
The rear fog lamp has been installed to the rear corner bumper on the driver’s side.
The lighting system is provided with headlamp auto-turn off function, auto lamp function^*, wiper-linked auto lamp function, welcome light function and coming home light function (Refer to ).

note ^*: There are auto lamp function controlled by the photo sensor (Standard: Refer to ) and auto lamp function controlled by the lighting control sensor (Option: Refer to ).
For the flasher timer function of turn-signal, the comfort flasher function has been adopted to improve the operability when changing the lane. When the turn-signal lamp switch (lighting switch) is operated for a short time, this function flashes the turn-signal lamp of the operated direction three times (Refer to ).

Headlamp manual levelling system

The beam direction of the headlamps changes according to the number of passengers and the amount of load. The headlamp manual levelling function is a system that allows the driver to change the direction of headlamp beam so that the drivers of oncoming cars are not dazzled by the headlamps. The headlamp levelling switch allows changing the direction in five steps: 0 to 4.

Passenger and load	One or two passengers	Five passengers	Five passengers and heavy loads	Driver and heavy loads
Switch position	0	1 or 2	3	4

Passenger and load	One or two passengers	Four passengers (front seat and third seat)	Seven passengers	Seven passengers and heavy loads	Driver and heavy loads

note

Each switch position is for reference. In each switch position, when the headlamp beam is too high, turn the switch to one-level higher position.

Operation

1.The headlamp levelling switch increases the resistance as it is turned from 0 to 4. Turning the headlamp levelling switch changes the voltage at point A. When the headlamp levelling switch is turned from 0 to 4, the voltage at point A decreases. Upon detection of this voltage change, the headlamp levelling unit turns the motor to lower the beam direction. At this time, the resistance of the variable resistor in the headlamp assembly changes, and the voltage at point B decreases gradually. When the voltages at points A and B become equal, the headlamp levelling unit stops the motor.
2.Turning the headlamp levelling switch from 4 to 0 increases the voltage at point A, and then the headlamp levelling unit turns the motor in the direction opposite to that mentioned in Item 1, increasing the voltage at point B. When the voltages at points A and B become equal, the headlamp levelling unit stops the motor.
3.The headlamp levelling unit detects voltage changes caused by headlamp levelling switch operation, and turns the motor to change the directions of the headlamp reflectors for the adjustment of the headlamp beam direction.

Headlamp automatic levelling system

The beam direction of the headlamps (vertical angle) changes according to the number of passengers and the amount of load. The headlamp automatic levelling system is a system that automatically controls the beam direction of headlamps (up and down angle) when parking or travelling with stable vehicle attitude so that the drivers of oncoming cars and of cars driving in front are not dazzled by the headlamp beam that is directed upwards.

Operational Description

The beam direction of headlamps is automatically controlled according to driving conditions as described in the table below.

Vehicle condition	Control content
When parking	When the engine is stopped with the headlamp (low-beam) ON or when the vehicle is stopped with the headlamp (low-beam) ON and the accelerator pedal is released, the headlamp automatic levelling-ECU controls the beam direction according to the height sensor values of the change in load resulting from getting on/off of passengers or loading/unloading of loads.
When driving at a constant speed	When a vehicle starts on curb, the travelling vehicle posture changes from the posture during parking, so that the beam direction changes. To control the improper beam direction caused by such vehicle attitude change, the headlamp automatic levelling ECU controls the beam direction while travelling with stable vehicle attitude. This beam direction control while travelling with stable vehicle attitude is performed only once between a vehicle stop and the next stop. When driving is started on a gravel or rough road, the beam direction control is activated after the vehicle attitude becomes stable on a paved road.
