Trailer Stability Assist (TSA)

If the vehicle sways while being driven and towing a trailer, the Trailer Stability Assist (TSA) automatically controls braking and engine torque to suppress the swaying and enhance vehicle stability.

The Trailer Stability Assist (TSA) is operable at a vehicle speed of about 65 km/h (40 mph) or more.

When the Trailer Stability Assist (TSA) operates while driving the vehicle, the TCS/DSC indicator light flashes.

Refer to TCS/DSC Indicator Light (Search).


Do not rely solely on the Trailer Stability Assist (TSA)

Assured vehicle stability is limited even if the Trailer Stability Assist (TSA) is operating. Drive carefully to prevent accidents.

In particular, if the TCS/DSC indicator light is flashing, drive the vehicle carefully as it is in a less stable condition and could sway more easily. Drive with caution and in accordance with the road, vehicle and trailer conditions.
