Selec-Speed Control (SSC) — If Equipped
Selec-Speed Control (SSC) is intended for
off-road driving in 4WD Low only. SSC main-
tains 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 overrid-
ing 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 fol-
lowing conditions must also be met to enable SSC:
•
The driveline is in 4WD Low.
•
The vehicle speed is below 5 mph (8 km/h).
•
The parking brake is released.
•
The driver door is closed.
•
The 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 PARK.
•
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=1.2mph(2km/h)
•
3rd=1.8mph(3km/h)
•
4th=2.5mph(4km/h)
•
5th=3.1mph(5km/h)
•
6th=3.7mph(6km/h)
•
7th=4.3mph(7km/h)
•
8th=5mph(8km/h)
•
9th = 5.6 mph (9 km/h) – If Equipped
•
REVERSE = .6 mph (1 km/h)
•
NEUTRAL = 1.2 mph (2 km/h)
•
PARK = SSC remains enabled but not active
NOTE:
•
During SSC the +/- shifter input is used for SSC tar-
get speed selection but will not affect the gear cho-
sen by the transmission. While actively controlling
SSC the transmission will shift appropriately for the
driver-selected set speed and corresponding driving
conditions.
•
SSC performance is influenced by the Select-Terrain
mode. This difference may be notable to the driver
and may be perceived as a varying level of
aggressiveness.
Driver Override:
The driver may override SSC activation with throttle or
brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any of
the following conditions occur:
•
Driver overrides SSC set speed with throttle or brake
application
•
Vehicle speed exceeds 20 mph (32 km/h) but
remains below 40 mph (64 km/h)
•
Vehicle is shifted to PARK
Disabling SSC
SSC will deactivate and be disabled if any of the follow-
ing conditions occur:
•
The driver pushes the SSC switch.
•
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) (SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offers feedback to the driver
about the state SSC is in.
•
The cluster icon and switch light will illuminate and
remain on solid when SSC is enabled or activated.
This is the normal operating condition for SSC.
•
The cluster icon and switch light will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enable conditions are not met.
