USING AND DRIVING
05
Vehicle Dynamic Control (VDC) Vehicle Dynamic Control (VDC)
If the vehicle swerves from the driver's
normal lane, the VDC will correct the
situation by engaging brakes to the
corresponding wheels to help control
skidding and maintain directional stability.
Traction Control System (TCS)
Traction Control System (TCS)
TCS prevents the drive wheels from
skidding when accelerating, and engages
brake control to prevent idling of drive
wheels when necessary. TCS makes the
vehicle easy to start, accelerate and climb
under adverse driving conditions.
WARNING
•
TCS effectiveness is affected under
the following conditions:
» When driving on slippery roads,
even if TCS is working properly,
it may not be able to control
the direction and meet power
requirements.
» Conditions where stability and
power may be lost.
Hill-start Hold Control (HHC) Hill-start Hold Control (HHC)
After the brake pedal is released, HHC
maintains brake pressure for 1 second to
prevent backward sliding.
Hydraulic Break Assist (HBA)
Hydraulic Break Assist (HBA)
When the brake pedal is pressed quickly,
HBA recognizes that the vehicle is in
emergency mode and actively improve the
brake pressure so that ABS can intervene
more quickly and effectively shorten the
brake distance.
Controller Deceleration Parking (CDP)* Controller Deceleration Parking (CDP)*
When the EPB switch is pulled, the CDP
function starts working and the vehicle
brakes at a constant deceleration (0.4 g
when the EPB is pulled without pressing
the brake pedal, and 0.8 g when EPB is
pulled with pressing the brake pedal) until
the vehicle stops, and it stops working if the
EPB is released.
Hill Descent Control (HDC)
Hill Descent Control (HDC)
Working principle: HDC is a value-added
function of the ESC system to improve
vehicle comfort, the main function of which
is to assist in uphill and downhill slow
driving through active braking.
• To enable or disable HDC:
• Tap on → Dipilot → Active Safety
→ Hill Descent Control to enable or
disable HDC.
• The HDC switch can also be pressed
when the speed is below 38 km/h.
When HDC is enabled, its status
indicator on the instrument cluster is
steady on.
• Press the HDC switch again to disable
the function, and the indicator goes OFF.
When the speed exceeds about 65 km/h,
the HDC automatically stops.
• When HDC is working, ABS will be
activated when the wheel slip exceeds
the ABS trigger threshold, allowing
the driver to safely and smoothly go
downhill, or even reverse.
