Range Rover Evoque: Gradient release control (GRC)
With HDC activated, if the vehicle is stopped on
a slope using the foot brake, GRC will become
active (except in Terrain Response Sand
program). It operates in all gears and in neutral
position.
During a steep hill descent, when the foot brake
is released GRC will automatically hold brake
force for a short period before gradually
releasing it, allowing for maximum control to
be retained.
During an uphill start, a similar brake hold and
gradual release is employed. This allows time
for the driver to apply speed and allow the
vehicle to move away smoothly.
