Hilldescentcontrol(HDC)
Note: HDC is automatically deselected if the
ignition is switched off for more than 6
hours.
BRAKE TEMPERATURE
In extreme circumstances, the HDC system may
cause brake temperatures to exceed their pre-
set 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.
2.
Increase the descent speed.
Each gear has a predetermined maximum
speed.
Note: Vehicle speed will only increase on a
slope steep enough to increase momentum.
Use of the + switch may; therefore, not
increase vehicle speed on a gentle slope.
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.
3.
Decrease the descent speed.
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 Dealer/Authorised Repairer as soon as
possible.
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). During a hill ascent when the foot
brake 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 HDC
is inoperative or warning messages
are displayed.
