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 oper-
ating the vehicle.
Summary of the driving assist
systems
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 brak-
ing 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
Enhanced VSC (Enhanced Vehi-
■
cle Stability Control)
Provides cooperative control of the
ABS, TRAC, VSC and EPS.
Helps to maintain directional stability
when swerving on slippery road sur-
faces by controlling steering perfor-
mance.

detected.
TRAC (Traction Control)
■
Helps to maintain drive power and pre-
vent the drive wheels from spinning

ing on slippery roads
Hill-start assist control
■
Helps to reduce the backward move-
ment of the vehicle when starting on an

EPS (Electric Power Steering)
■

the amount of effort needed to turn the
steering wheel
Dynamic Torque Control AWD
■
system (if equipped)
Automatically switches from front-
wheel drive to all-wheel drive (AWD)
according to the driving conditions,
helping to ensure reliable handling and
stability. Examples of conditions where
the system will switch to AWD are
when cornering, going uphill, starting
off or accelerating, and when the road
surface is slippery due to snow, rain,
etc.
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
the road and driving conditions, this
