Manual Trailer Brake Apply Lever
Slide this lever left to apply the
trailer’s electric brakes independent of
the vehicle’s brakes. Use this lever to
adjust Trailer Gain to achieve the
proper power output to the trailer
brakes. The trailer's and the vehicle's
brake lamps will come on when either
vehicle brakes or manual trailer brakes
are applied and properly connected.
Trailer Gain Adjustment Procedure
Trailer Gain should be set for a
specific trailering condition and it
must be readjusted anytime vehicle
loading, trailer loading, or road surface
conditions change.
{
Warning
Trailer brakes that are over-gained
or under-gained may not stop the
vehicle and the trailer as intended
and can result in a crash. Always
follow the instructions to set the
Trailer Gain for the proper trailer
stopping performance.
To adjust Trailer Gain for each towing
condition:
1. Drive the vehicle with the trailer
attached on a level road sur face
representative of the towing
condition and free of traffic at
about 32 to 40 km/h (20 to
25 mph) and fully apply the
Manual Trailer Brake apply lever.
Note
Adjusting Trailer Gain at speeds lower
than 32 to 40 km/h (20 to 25 mph)
may result in an incorrect gain
setting.
2. Adjust the Trailer Gain, using the
Trailer Gain adjustment buttons,
to just below the point of trailer
wheel lock-up, indicated by
trailer wheel squeal or tire smoke
when a trailer wheel locks.
Note
Trailer wheel lock-up may not occur if
towing a heavily loaded trailer. In this
case, adjust the Trailer Gain to the
highest allowable setting for the
towing condition.
3. Readjust Trailer Gain any time
vehicle loading, trailer loading,
or road sur face conditions
change or if trailer wheel lock-up
is noticed at any time while
towing.
