level surface at a speed of 20–25 mph (30–40 km/h) and
squeeze the manual brake control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires),
reduce the GAIN setting; if the trailer wheels turn freely,
increase the GAIN setting.

below trailer wheel lockup. If towing a heavier trailer, trailer
wheel lockup may not be attainable even with the maximum
GAIN setting of 10.

may also affect the selection.
