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.

operating.
GAC will limit vehicle acceleration on steep
descents, allowing the driver to feel more in
