• There are two types of headlamp assemblies: 

halogen type and discharge type (optional for 
2.4L model).

• The headlamp assembly employs the four-lamp 

integrated with the headlamp (low-beam), head-
lamp (high-beam), front turn-signal lamp, and 
position lamp.

• The newly adopted discharge headlamp for low 

beam provides a much better view than ordinary 
halogen lamps. <Vehicles with discharge type 
headlamp>

• Switching of the high-beam and low-beam illumi-

nation of the discharge type headlamp is control-
led 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 

P.54A-5

.) and the 

headlamp automatic levelling system <Vehicles 
with discharge type headlamp> (Refer to 

P.54A-6

.) have been adopted so that the height 

adjustment of the optical axis can be performed 
depending on the vehicle load status.

• The fog lamp have been installed to above the 

front bumper.

• The rear fog lamp and back-up lamp have been 

installed to the rear bumper.

• 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 lamp are integrated with 

the stop/tail lamp and rear turn-signal lamp.

• The LED-type high-mounted stop lamp have 

been integrated into the tailgate.

• The licence plate lamp have been installed to 

above the licence plate.

• The lighting system is provided with headlamp 

automatic-shutdown function, auto lamp function, 
welcome light function and coming home light 
function (Refer to 

P.54A-10

).

• For the flasher timer function of turn-signal lamp, 

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 

P.54A-10

).

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 func-
tion 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.

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 level-
ling 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 ETACS-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 ETACS-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.
