Vehicle driving controls
Such incidents mostly happen at high speed, but, there is also a risk of swaying when the
trailer is affected by crosswinds, buffeting or improper overloading.
Factors of swaying such as:
僅 High speed
僅 Strong crosswinds
僅 Improper overloading
僅 Sudden controlling of steering wheel
僅 Uneven road
The TSA continuously analyzes the vehicle and trailer instability. When the Trailer Stability
Assist (TSA) detects sway, the brakes are applied automatically on the wheels and the
engine power is properly reduced to stabilize the vehicle. When the vehicle becomes sta-
ble, the TSA does not operate.
Active air flap
Active air flap system controls the air flap below the front bumper to cool the vehicle parts
and improve energy efficiency.
