Hill-Start Hold Control (Hhc) System - MG HECTOR Quick Start Manual

SAFETY

16 - HILL-START HOLD CONTROL (HHC) SYSTEM*

HHC helps the vehicle to start easily on a slope without using the parking brake. HHC provides
assistance by preventing the vehicle from rollback.
HHC operates after vehicle brake pedal is released and maintains the braking force for 1-2 seconds so
that vehicle will not rollback
In these 2 seconds, if acceleration input is greater than vehicle uphill resistance, HHC gradually reduces
braking force and vehicle runs smoothly
If acceleration input is lesser than vehicle uphill resistance, then HHC will reduce brake pressure and
vehicle may rollback. Here, brake pedal needs to be pressed to stop vehicle.
HHC will function only when vehicle is stationary and brake pedal is depressed

The HHC function may fail to prevent the vehicle from sliding a slope on a very slippery or steep hillside. Only as one
driver-assistance measure,the HHC function cannot supersede the parking brake function.
*Only in vehicle with CVT/AT Transmission
