The cluster icon and switch lamp will flash

for several seconds then extinguish when
HDC disables due to excess speed.
The cluster icon and switch 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.
Selec Speed Control (SSC) — If Equipped
Selec Speed Control (SSC) is intended for off
road driving in 4L only. SSC maintains
vehicle speed by actively controlling engine
torque and brakes.
SSC has three states:
1. Off (feature is not enabled and will not
activate).
2. Enabled (feature is enabled and ready
but activation conditions are not met, or
driver is actively overriding with brake or
throttle application).
3. Active (feature is enabled and actively
controlling vehicle speed).
Enabling SSC
SSC is enabled by pushing the SSC switch,
but the following conditions must also be
met to enable SSC:
Driveline is in 4L Range

Vehicle speed is below 5 mph (8 km/h)

Park brake is released

Driver door is closed

Driver is not applying throttle

Activating SSC
Once SSC is enabled it will activate automat-
ically once the following conditions are met:
Driver releases throttle

Driver releases brake

Transmission is in any selection other than

PARK (P)
Vehicle speed is below 20 mph (32 km/h)

The set speed for SSC is selectable by the
driver, and can be adjusted by using the gear
shift +/-. Additionally, the SSC set speed
may be reduced when climbing a grade and
the level of set speed reduction depends on
the magnitude of grade. The following
summarizes the SSC set speeds:
SSC Target Set Speeds
1st = .6 mph (1 km/h)

2nd = 1.2 mph (2 km/h)

3rd = 1.8 mph (3 km/h)

4th = 2.5 mph (4 km/h)

5th = 3.1 mph (5 km/h)
