# Info-Proper Setting of IP Dimmer to View PRNDL w/Auto Headlamp Control

Subject: | Proper Setting of I/P Dimmer Control To View PRNDL Display with Automatic Headlamp Control

Models: | 2000 and Prior All Passenger Cars and Trucks

| With Automatic Headlamp Control and Electronic PRNDL Display

Under certain conditions, if the instrument panel dimmer control is turned relatively low, the PRNDL will not be visible until the automatic headlamp control turns the headlamps off and the daytime running lamps (DRL) are turned back on. Such a condition may be if the vehicle is first started in an environment where the headlamp control turns on the headlamps and then the vehicle is driven out into a brighter environment (for example, when a vehicle is backed out of a dark garage into the bright sunlight).

This condition is normal and any repair attempt will not be successful. Demonstrate this condition to the customer using the service lane and then turn the instrument panel dimmer control to a higher setting. This will enable the driver to see the PRNDL display.
