Before removing any switch, disconnect the battery negative lead and position the lead away from the battery. To remove the headlight, first take off the front bumper, then unscrew the two securing screws on top of the unit and lift the mountings to release them from the front panel. Use a screwdriver to prise up the retaining tab at the front lower corner of the light unit, then pull the unit forwards slightly to disconnect the outer rear securing clip. Slide the unit forwards and disconnect the four wiring connectors from the back of the headlight, which include three bulbholders and one adjustment motor, before removing it. If the headlight is damaged, the lens can be unclipped and replaced, ensuring to check the condition of the seal between the lens and the light unit. Reinstallation follows the reverse order of removal. The front indicator is integral with the headlight. For the front foglight, turn the steering wheel for better access to the front of the wheel arch, remove the three cross-head screws securing the front half of the wheel arch liner, and pull the liner back to access the bulbholder. Disconnect the wiring plug by pressing the back and pulling it down, then carefully prise the foglight front trim panel from the bumper using a small screwdriver. Remove the mounting bolt at the back, unclip, and take out the light from the bumper, with reinstallation being the reverse of removal. The procedure for the indicator side repeater light is included in the bulb renewal process. To access the rear lights, open the tailgate and unclip the trim panel from the back of the light unit to reach the bulbholders. Disconnect the wiring plug from the bulbholder, support the light from outside, and unscrew the central nut from the back of the light. Remove the light from the car, noting it may be stuck on the body seal, and ensure to check the condition of the body seal before fitting the light back, replacing it if necessary to prevent water leaks. The procedure for the rear number plate light and high-level stop-light is also part of the bulb renewal process, where instead of twisting the bulbholder off the light, the wiring plug on the back of the bulbholder should be disconnected.

Accurate adjustment of the headlight beam is only possible using optical beam-setting equipment, and this work should therefore be carried out by a Toyota dealer or a suitably-equipped workshop.
