The headlight of all models consists of four halogen bulbs, and projector type low beam lights are used.
The front turn signal/hazard warning light, parking/front side marker light and the front side reflex reflector are incorporated into the headlight.
The fog light is either of a projector type or a large sized multiple reflector type.
On some models, the side turn signal lights are built into the lower part of the door mirrors to improve visibility. Also, LEDs (light emitting diodes) are used for light source to improve the durability.
