Using the Integrated Trailer Brake Controller

Make sure the trailer brakes are in good working condition, functioning normally and properly adjusted. See your trailer dealer if necessary.

Note: An authorized dealer can diagnose the trailer brake controller to determine exactly which trailer fault has occurred. Your vehicle warranty does not cover issues with your trailer.

Hook up the trailer and make the electrical connections according to the trailer manufacturer's instructions.

Note: Select default mode if the trailer has surge brakes, or no brakes at all. The system has no effect on the braking performance of the trailer in either of these cases.

Note: If a trailer is connected by a four-pin connector, the trailer braking function will not be supported.

When you plug in a trailer with electric or electric-over-hydraulic brakes, a message confirming connection appears in the information display.

Use the gain adjustment to find the desired starting point. A gain setting of 6.0 is a good starting point for heavier loads.

Note: Use the following steps to adjust the gain setting whenever road, weather and trailer, or vehicle loading conditions, change from when you initially set the gain.

In a traffic-free environment, tow the trailer on a dry, level surface and squeeze the manual control lever completely.

If the trailer wheels lock up, indicated by squealing tires, reduce the gain setting. If the trailer wheels turn freely, increase the gain setting. Repeat Steps 5 and 6 until the gain setting is at a point just below trailer wheel lock-up. If towing a heavier trailer, trailer wheel lock-up may not be attainable even with the maximum gain setting of 10.

Note: Only perform this procedure at speeds of approximately 20–25 mph (30–40 km/h).

Note: The trailer brake controller reduces output at vehicle speeds below 11 mph (18 km/h) so that trailer and vehicle braking is not jerky or harsh. This feature is only available when applying the brakes using your vehicle's brake pedal, not the controller.

Note: Your vehicle's brake system and the trailer brake system work independently of each other. Changing the gain setting on the controller does not affect the operation of your vehicle's brakes whether you attach a trailer or not.

Note: With the proper electrical connection, pressing your vehicle brake pedal or using the manual control lever illuminates both trailer and vehicle brake lamps.

Note: When you switch the engine off, the controller output is disabled and the display and module shut down. The controller module and display turn on when you switch the ignition on.

Adjusting the Trailer Brake Gain

Increase or decrease the amount of gain in set increments.
B

Slide the control to engage the trailer brakes.

Note: Adjust gain setting before using the trailer brake controller for the first time.

Note: The gain should be set to provide the maximum trailer braking assistance while making sure the trailer wheels do not lock when using the brakes. Locked trailer wheels may lead to trailer instability.

Note: Setting adjustments are saved when a trailer profile is selected.

Note: If you have installed an aftermarket trailer brake controller in addition to the integrated trailer brake controller, set the gain on the integrated trailer brake controller to zero.
