TSA may not intervene when the vehicle
and trailer begin to sway if the driver tries
to compensate for the swaying motion by
moving the steering wheel rapidly
How TSA works
Once swaying has begun, it can be very diffi-
cult to stop, which makes it difficult to control
the vehicle and trailer.
The TSA system continuously monitors the
vehicle's movements, particularly lateral
movement. If the system detects a tendency
to sway, the brakes are applied individually
on the front wheels, which has a stabilizing
effect on the vehicle and trailer. This is often
enough to enable the driver to regain control
of the vehicle.
If this is not adequate to stop the swaying
motion, the brakes are applied to all of the
wheels on the vehicle and on the trailer if it is
equipped with brakes, and engine power is
temporarily reduced. As the swaying motion
begins to decrease and the vehicle-trailer
have once again become stable, TSA will now
stop regulating the brakes/engine power and
the driver regains control of the vehicle.

tion slot for the entire time that the vehi-
cle is being towed.
3. Keep the tow rope taut when the towing
vehicle slows down by applying light
pressure on the brake pedal. This will
help prevent jarring movements of the
vehicle being towed.
