To help enhance driving safety and performance, the following sys-
tems 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

VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces

TRC (Traction Control)
Helps to maintain drive power and prevent any of the drive wheels
from spinning when starting the vehicle or accelerating on slippery
roads

Hill-start assist control
P. 299

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 vehicle conditions such
as steering wheel movement and vehicle speed in order to maintain
a stable vehicle posture

VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, TRC, VSC,
hill-start assist control and EPS systems
Helps to maintain vehicle stability when swerving on slippery road
