Driving assist systems  
To help enhance driving safety and performance, the following  
systems operate automatically in response to various driving  
situations. Be aware, however, that these systems are supple-  
mentary and should not be relied upon too heavily when operat-  
ing the vehicle.  
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.  
TRC (Traction Control)  
Helps to maintain drive power and prevent the front wheels from  
spinning when starting the vehicle or accelerating on slippery  
roads.  
Hill-start assist control  
Helps to prevent the vehicle from rolling backward when starting on  
an incline or slippery slope.  
EPS (Electric Power Steering)  
Employs an electric motor to reduce the amount of effort needed to  
turn the steering wheel.
