Interior light controls are listed here in alphabetical order.

The interior lights include panel lights, dome lights, reading lights, and courtesy lights.

Vehicles come pre-set from the factory with theater lighting, which ramps up lights from low power to full power when activated. See Fig..

Sleepers have rear dome lights, ambient lights, reading lights, task lights, foot well lights, and baggage compartment lights.

Many interior lights have a dimming function. By holding down the switch, the lights can be cycled between bright and dim.

Baggage Compartment Lights

Baggage compartment lights are located on the underside of the lower bunk, on both sides. Both lights turn on when either baggage compartment door is opened to illuminate the baggage compartment. The lights also come on when the lower bunk is raised.

Foot Well Lights

When the driver or passenger doors are opened, amber lights illuminate both foot wells. These lights can also be activated with the foot well light switch. See Fig.. Press the upper half of the switch to turn the foot well lights on or off.

Overhead Console Lights

The overhead console lights consist of two dome lights, two reading lights, and an amber lamp that provides ambient light for the center dash panel and the cup holders. The dome lights illuminate when a door opens, then stay on for a short time after both doors are closed. Press the lens of the reading light or dome light to activate each one independently of the others.

Dash Lights

The dash lighting illuminates independently of the headlights. The brightness can be set to adjust automatically based on ambient lighting.

The brightness can also be adjusted in either the ICUC or ICC5 under the Settings menu or through the use of an optional dash switch.

When using the dash switch, the panel lights brighten and dim in 10% increments, depending on whether the upper half or the lower half of the switch is pressed. When the panel lights are turned on with the switch, they will default to the intensity that was last set.

Cab Dome Light

A rear cab dome light is located on the headliner, between the bunk and the cab on sleeper vehicles. The rear cab dome light will activate with the dome lights when a door is opened, then stay on for a short time after both doors are closed. The length of time this courtesy lighting stays on can be controlled via the settings menu in any ICU system as can the time the entrance light stays on.

Use the dash-mounted switch or the switch in the sleeper panel to activate the rear cab dome light. See Fig..
