To replace exterior light bulbs, start with the front turn signal/parking light by removing the air filter housing, then turn the bulb holder counterclockwise to remove it from the headlight housing without disconnecting the electrical connector. Pull the bulb straight out of the holder and reinstall in reverse order. For sidemarker light bulbs, work inside the inner fenderwell to squeeze the locking tab and push the marker housing out, then turn the bulb holder counterclockwise to remove it. Pull the bulb straight out and reinstall in reverse order. For fog light bulbs, raise the front of the vehicle, remove the inner fender splash shield, disconnect the electrical connector, and turn the bulb counterclockwise to remove it. Insert the new bulb and turn it clockwise to lock it in place. For daytime running light (DRL) bulbs, remove the air filter housing, take off the headlight bulb cover, disconnect the electrical connector, and turn the bulb counterclockwise to remove it. Insert the new bulb and turn it clockwise to lock it in place. The center high-mounted brake light is integral to the housing and not separately serviceable; for coupe models, remove the rear package tray or trunk lid panel, disconnect the electrical connectors, and remove the light. For convertible models, disconnect the stoplight electrical connector, pry up the rear window upper trim panel, and remove the light. For taillight bulbs, open the trunk, remove the taillight filler panel, turn the bulb holder counterclockwise, and pull the bulb straight out. For license plate light bulbs, open the trunk lid, press the release tab on the lens, disconnect the electrical connector, and remove the bulb from the socket. For interior light bulbs, pry off the overhead lens, pull the bulb straight out, and reinstall in reverse order. For cargo light bulbs, open the trunk, pry out the cargo light, disconnect the electrical connector, and remove the bulb from the terminals, reinstalling in reverse order.

To replace the front parking/turn signal bulbs one has to first remove the head- light housing and the dust shield off the bulb. Twist the bulb holder anti-clockwise and pull it to unseat the bulb then remove the electrical connector. For center high-mounted brake light on sedan models, it is necessary to remove all the trim if any in the trunk lid, then unlite the electrical connector and for early models, two mounting nuts should be removed to pull out the light. The latest models call for the elimination of the plastic casing to get to individual bulbs. More specifically, in coupe models you will have to pop open the package tray on the inner trunk lid and cut through some foam on the inner part of the gille speakers, you will then have to take out the rear retainers behind and angle the brake light forward so as to be removed easily. For license plate light bulbs, unscrew the screws on the housing and flip the light forward and downward to pull it out and to take the light socket counter clockwise. For taillight, back-up light, brake light, and turn-signal bulbs, one has to unclip the side inner trunk trim panel, remove the mounting nuts, pull the taillight to the rear or side, disconnect the electrical connector, and one has to ensure that the locating pin fits correctly during the assembly. The taillight housing has to be laid on a clean surface to replace the bulbs and this is done by unscrewing the bulb holders anti-clockwise. For fog lights, safely lift the car, pry off the inner fender liner; unplug the wiring, while in early models you need to unscrew the fog light to pull it out from its mount. In later variants, unplug the electrical connection and twist the latches of the bulb assembly to install a new bulb. To replace interior lights, remove the dome light or map reading light lens, pull out bulb from the retaining wire and replace the bulb in the reverse of the described process.
