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 supplementary and should not be relied
upon too heavily when operating 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.
■ Enhanced VSC (Enhanced Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■
TRAC (Traction Control)
Helps to maintain drive power and prevent the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■ Hill-start assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operates for approximately 5 seconds at maxi-
mum.
■
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
■ Active stabilizer suspension system (if equipped)
Reduces sway when cornering according to steering wheel movement
and the selected suspension damping mode, in order to maintain a stable
vehicle posture.
■ PCS (Pre-Collision System) (if equipped)
