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 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 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)
- 3rd = 1.8 mph (3 km/h)
- 4th = 2.5 mph (4 km/h)
- 5th = 3.1 mph (5 km/h)
- 6th = 3.7 mph (6 km/h)
- 7th = 4.3 mph (7 km/h)
- 8th = 5 mph (8 km/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 target
speed selection but will not affect the gear chosen by
the transmission. While actively controlling SSC the
transmission will shift appropriately for the driverselected
set speed and corresponding driving conditions.
- SSC performance is influenced by the Terrain Select
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 following
conditions occur:
- The driver pushes the SSC switch.
- The driveline is shifted out of 4WD Low Range.
- The parking brake is applied.
- 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 offer feedback to the driver
about the state SSC is in.
- The cluster icon and switch lamp 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 lamp will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enable conditions are not met.
- The cluster icon and switch lamp will flash for several
seconds then extinguish when SSC disables due to
excess speed.
- The cluster icon and switch lamp will flash then
extinguish when SSC deactivates due to overheated
brakes.
WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off road conditions.
The driver must remain attentive to the driving
conditions and is responsible for maintaining a safe
vehicle speed.
