Driving assist systems

To help enhance driving safety and performance, the following systems oper-
ate 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.
■
VSC (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 drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■
Hill-start assist control
Helps to reduce the vehicle' s rolling backward distance 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.
■
VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, VSC, TRAC, and hill-
start assist control systems.
Helps to maintain vehicle stability when swerving on slippery road surfaces
by controlling the brakes and engine output.
When switched to SPORT driving mode, the control characteristics of the
VDIM system are altered.
