Exterior Moulding / Trim: Description and Operation

Exterior Trim

The exterior trim and ornamentation consists of the:

- window mouldings.
- running boards.
- Power Running Boards (PRBs) (if equipped).
- PRB step.
- PRB motor (includes linkage).
- PRB step end caps.
- PRB module.

The PRB step end caps can be serviced separately.

If equipped, the PRBs automatically move when the doors are opened to assist entering and exiting the vehicle.

The PRB feature may be enabled/disabled through the message center. For information on how to access the PRB feature within the message center, refer to the Owner's Literature.

When the PRB is disabled (OFF), the PRBs will immediately move to the stowed position regardless of the position of the doors.

When the PRB is enabled (AUTO), the PRBs will extend when the doors are opened and return to the stowed position when the doors are closed or vehicle speed is greater than 8 km/h (5 mph).

When the PRBs are manually set to the deployed position (OUT), they will return to the stowed position and AUTO mode when the vehicle speed is greater than 8 km/h (5 mph).
