Active Rollover Protection (Arp); Hill Descent Control (Hdc) System - MG RX5 Handbook

Active Rollover Protection (ARP)

ARP system is just a kind of safe-assistant
device, which cannot possibly surpass the
physics laws to guarantee the vehicle from
rollover.
In case that the vehicle with high centre of mass due to
dual-direction lane-change may roll over, ARP brakes the
outside wheels to under-steer, thereby preventing the
vehicle from rollover.
Note: With ARP in use, the vehicle under-steers and it
is normal if it fails to steer fully according to the intent
of the driver during the operation of ARP.

Hill Descent Control (HDC) System

HDC system is an auxiliary function specially designed for
driving on acute downhill surface. HDC system reduces
the speed by applying the brake force, thus assists the
driver to drive on acute downhill surface with low speed.
Therefore, please do not use this function when driving on
the ordinary road.
HDC system is just an auxiliary function for
comfort. Even when HDC system is in use,
the driver shall still pay close attention to
the driving state of the vehicle, and take
active control when necessary. Because in
certain cases, HDC may remove itself from
the operating state temporarily.
Under some driving conditions on downhill
surfaces (e.g. driving down a slope with high
speed), HDC is inoperative, so the driver
shall be required to control the speed by
depressing the brake pedal to ensure the safe
driving.
