4-5. Using the driving support systems
Driving
Q ECB (Electronically Controlled
Brake System)
The electronically controlled system
generates braking force correspond-
ing to the brake operation
Q 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
Q Brake assist
Generates an increased level of brak-
ing force after the brake pedal is
depressed when the system detects a
panic stop situation
Q VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning on
slippery road surfaces
Q 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.
Q Secondary Collision Brake (if
equipped)
When the SRS airbag sensor detects a
collision and the system operates, the
brakes and brake lights are automati-
cally controlled to reduce the vehicle
speed and help reduce the possibility
of further damage due to a secondary
collision.
Q TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads
Q Active Cornering Assist (ACA)
Helps to prevent the vehicle from drift-
ing to the outer side by performing
inner wheel brake control when
attempting to accelerate while turning
Q Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill
Q EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel
Q AVS (Adaptive Variable Suspen-
sion system) (if equipped)
By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
Driving assist systems
To keep driving safety and perfor-
mance, 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.
