Dome Lamp


Object Number: 809959  Size: B3

The dome lamp operates as follows:

OFF: This position is to the left when you are sitting in the driver's seat. The dome lamp will stay off even when a door is opened.

Center: The lamp will come on when a door is opened. The dome lamp will turn off while all doors are shut.

ON:  This position is to the right when you are sitting in the driver's seat. The dome lamp will turn on and stay on whether or not a door is open.

Entry Lighting

If your vehicle has remote keyless entry, it is equipped with an entry lighting feature that controls your dome lamp (and cargo lamp, if equipped). For the dome lamp to operate as described below, the switch must be in the middle position.

Your interior lamps will come on and stay on for a set time whenever you press the UNLOCK button on the remote keyless entry transmitter.

If you open any door, the lamps will stay on while the door is open, then turn off automatically about 40 seconds after the last door is closed. If you press the UNLOCK button on the remote keyless entry transmitter and don't open a door, the lamps will come on and then turn off after about 40 seconds.

The lamps will turn off immediately if you turn the ignition key to ON. When the ignition is on, the entry lighting feature is inactive. The interior lamps will come on only if they are turned on by the dome lamp switch or one of the doors is opened.

When you press the LOCK button on the remote keyless entry transmitter, the interior lamps will come on for about three seconds, and then shut off.

Your vehicle may have a cargo lamp. The cargo lamp comes on when any door is opened, and goes off when all doors are shut.
