Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
The driver pushes the HDC button.
The driveline is shifted out of 4WD Low.
The parking brake is applied.
The driver door opens.
The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds.
The vehicle is driven greater than 40 mph
(64 km/h) (HDC exits immediately).
HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the
HDC button has an LED icon, which offers
feedback to the driver about the state HDC is in.
The cluster icon and button lamp will illuminate
and remain on solid when HDC is enabled or
activated. This is the normal operating condition
for HDC.
The cluster icon and button lamp will flash for
several seconds then extinguish when the driver
pushes the HDC button but enable conditions
are not met.
The cluster icon and button lamp will flash for
several seconds then extinguish when HDC
disables due to excess speed.
The cluster icon and button lamp will flash when
HDC deactivates due to overheated brakes. The
flashing will stop and HDC will activate again
once the brakes have cooled sufficiently.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending hills.
The driver must remain attentive to the driving
conditions and is responsible for maintaining a
safe vehicle speed.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a
complete stop while on an incline. If the driver
releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for a
short period. If the driver does not apply the
throttle before this time expires, the system will
release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for
HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans-
mission is in PARK or NEUTRAL.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver's responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.
