4. Remove the xenon bulb.
5. Install in the reverse order of removal.
CAUTION:
IWhen disposing of the xenon bulb, do not break it; always
dispose of it as is.
IMake sure to install the bulb securely; if the xenon bulb is
improperly installed in its socket, high-tension current
leaks occur. This may lead to a melted bulb and/or bulb
socket.

The ground for all of the components except for compass, glove box lamp and ashtray are controlled through
terminals 2 and 3 of the illumination control switch and body grounds M77 and M111.
BATTERY SAVER CONTROLNBEL0035S02When the ignition switch is turned from ON (or START) to OFF (or ACC) positions while illumination lamps
are illuminated, the RAP signal is supplied to terminal 10 of the headlamp battery saver control unit from smart
entrance control unit terminal 5.
After counting 45 seconds by the RAP signal from the smart entrance control unit to headlamp battery saver
control unit, the ground supply to terminal 1 of the tail lamp relay from headlamp battery saver control unit
teminals 6 and 14 is terminated.
Then illumination lamps are turned off.
Illumination lamps are turned off when driver or passenger side door is opened even if 45 seconds have not
passed after the ignition switch is turned from ON (or START) to OFF (or ACC) positions while illumination
lamps are illuminated.
When the lighting switch is turned from OFF to 1ST (or 2ND) after illumination lamps are turned off by the
battery saver control, ground is supplied
Ito headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11, and
Ito tail lamp relay terminal 1 from headlamp battery saver control unit terminals 6 and 14.
Then illumination lamps illuminate again.
NOTE:
For Trouble Diagnoses for battery saver control, refer to ªPARKING, LICENSE AND TAIL LAMPSº
(EL-66).
