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)

NOTE:The system will automatically time out and the
ignition will cycle to the OFF mode after 30 minutes of
inactivity if the ignition is left in the ACC or RUN (engine
not running) mode and the transmission is in PARK.
ENGINE START/STOP Button Functions — With Driv-
er ’s Foot OFF The Brake Pedal (In PARK Or NEUTRAL
Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three modes: OFF, ACC, and RUN.
To change the ignition modes without starting the vehicle
and use the accessories, follow these steps:
• Starting with the ignition in the OFF mode,
• Push the ENGINE START/STOP button once to place
the ignition to the ACC mode (instrument cluster will
display “ACC”),
• Push the ENGINE START/STOP button a second time to
place the ignition to the RUN mode (instrument cluster
will display “ON/RUN”),
• Push the ENGINE START/STOP button a third time to
return the ignition to the OFF mode (instrument cluster
will display “OFF”).If Engine Fails To Start
