Range Rover Evoque - GRADIENT RELEASE CONTROL (GRC); WARNING MESSAGES; BRAKE TEMPERATURE

2. Increase the descent speed: The
Cruise control (+) button will increase
the HDC descent speed in 1 km/h (0.6
mph) increments. Press and hold the
(+) button for larger incremental
increases, up to the maximum
permissible target speed.
Note: Each gear has a predetermined
maximum speed.
Note: The vehicle's speed will only
increase on a slope steep enough to
increase momentum. Use of the (+)
switch may, therefore, not increase the
vehicle's speed on a gentle slope.
3. Decrease the descent speed: The
Cruise control (-) button will decrease
the HDC descent speed in 1 km/h (0.6
mph) increments. Press and hold the
(-) button for larger incremental
increases, down to the minimum
permissible target speed.
Note: Each gear has a predetermined
minimum speed.
If a fault is detected in the HDC system,
HDC FAULT SYSTEM NOT AVAILABLE
will appear in the Message centre and
HDC assistance will fade out.
If the fault is detected while the system is
operating, HDC assistance will fade out.
Contact a Retailer/Authorised Repairer as
soon as possible.
GRADIENT RELEASE CONTROL
(GRC)
With Hill Descent Control (HDC) activated,
if the vehicle is stopped on a slope using
the brake pedal, GRC will become active
(except in the Terrain response system's
Sand program). During a hill ascent, when
the brake pedal is released, GRC will
automatically delay and graduate the
brake release, to allow the vehicle to move
smoothly away. When descending a hill,
a similar brake hold and gradual release
is employed to provide a smooth
transition into HDC control.
GRC operates in forward and reverse
gears and requires no driver intervention.
WARNING MESSAGES
Do not attempt a steep descent
if Hill Descent Control (HDC) is
inoperative or if any warning
messages are displayed in the
Message centre.
BRAKE TEMPERATURE
In extreme circumstances, the Hill Descent
Control (HDC) system may cause brake
temperatures to exceed their preset limits.
If this occurs, the warning HDC
TEMPORARILY UNAVAILABLE will be
displayed in the Message centre. HDC will
then fade out and become temporarily
inactive.
Once the brakes have reached an
acceptable temperature, the message will
disappear (or the warning lamp will
extinguish) and HDC will, if required,
resume operation.
