Driving assist systems

To keep driving safety and performance, the following systems operate automat-
ically in response to various driving situations. Be aware, however, that these
systems are supplementary and should not be relied upon too heavily when
operating the vehicle.
■ ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corresponding to the
brake operation.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes
are applied while driving on a slippery road surface.
■ Brake assist
Generates an increased level of braking force after the brake pedal is depressed
when the system detects a panic stop situation.
VSC (Vehicle Stability Control)
■
Helps the driver to control skidding when swerving suddenly or turning on slippery
road surfaces.
■ VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road surfaces by
controlling steering performance.
■ Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake pressure for
individual wheels and reducing driving torque when trailer sway is detected.
■ TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning when
starting the vehicle or accelerating on slippery roads
Active Cornering Assist (ACA)
■
Helps to prevent the vehicle from drifting to the outer side by performing inner
wheel brake control when attempting to accelerate while turning.
■ Hill-start assist control
Helps to reduce the backward movement of the vehicle when starting on an uphill.
