Driving assist systems

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.
■
TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■
A-TRAC (Active Traction Control) for 4WD mode on 4WD
models
Maintains drive power and prevents the all wheels from spinning when
starting the vehicle or accelerating on slippery roads.
