The interior lamps have two modes of operation; automatic or manual. In the automatic mode the interior lamp

on and off using the momentary button adjacent to the front interior lamp or can be disabled completely using the
same switch.
NOTE: The LED illumination of the front door pockets and the front and rear interior door handles is a function of the
LCM and only operates when the light control switch is in the side lamp or headlamp positions.
The following table shows the bulbs used for the interior lighting and their type and rating:
Front and Rear Interior Lamps and Map Reading Lamps
The front and rear interior lamp assemblies are similar in design. The front interior lamp switch is connected directly
to the BCU and controls the manual operation of the interior lamp functionality. The rear interior lamp switch is used
only to switch the lamp on and off.
The map reading lights have a non-adjustable beam and are controlled via separate switches. Both the interior and
map reading lamps use capless 5W bulbs.
Luggage Compartment Lamps
The luggage compartment lamps comprise one lamp unit located on the RH side trim panel, adjacent to the auxiliary
power socket, and two lamps located in the interior trim panel of the upper tail door. All of these lamps are of the same
design and use capless 5W bulbs. The lamps are controlled by the BCU and operate on the automatic interior lamp
functionality.
Glovebox Lamp
The glovebox lamp is located inside the glovebox, at the top, adjacent to the latch. The lamp comprises a festoon 5W
bulb. The lamp housing also incorporates a plunger type switch which is activated to switch the lamp on when the
glovebox lid is opened.
