in the trailer, there is risk of swaying at speeds
between approximately 45-55 mph
(70-90 km/h).
NOTE
•
The TSA system intervenes at speeds
above approximately 40 mph
(60 km/h).
•
The DSTC symbol (
) in the instru-
ment panel will flash when TSA is work-
ing.
•
If the driver switches off the
DSTC sys-
tem's Spin Control function (see
page 155), TSA will also be switched off.
•
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.
Swaying may be caused by one of the following
factors:
•
The vehicle and trailer are hit by a sudden,
strong crosswind
•
The vehicle and trailer are traveling on an
uneven road surface or drive over a bump
•
Sudden movements of the steering wheel
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 vehi-
cle.
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 no stop
regulating the brakes/engine power and the
driver regains control of the vehicle.
