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 re-
sponsible for maintaining a safe vehicle speed.
Selec Speed Control (SSC) — If Equipped
SSC is intended for off road driving in 4WD Low Range
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 activationconditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling ve- hicle speed).
Enabling SSC
SSC is enabled by pushing the SSC switch, but the follow-
ing conditions must also be met to enable SSC:
• Driveline is in 4WD Low Range. •
Vehicle speed is below 5 mph (8 km/h).
• Parking brake is released.
• Driver door is closed.
• Driver is not applying throttle.
Activating SSC
Once SSC is enabled it will activate automatically once the
following conditions are met:
• Driver releases throttle.
• Driver releases brake.
• Transmission is in any selection other than 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)
