292 SAFETY
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 = 0.6 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 = 0.6 mph (1 km/h)
NEUTRAL = 1.2 mph (2 km/h)
PARK = SSC remains enabled but not active
NOTE:
During SSC, the +/- gear selector input is
used for SSC target speed selection but will
not affect the gear chosen by the transmis-
sion. While actively controlling SSC, the trans-
mission will shift appropriately for the
driver-selected set speed and corresponding
driving conditions.
SSC operation is influenced by Off Road+
drive mode if active. The differences may be
notable to the driver 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:
The driver overrides SSC set speed with
throttle or brake application.
The vehicle speed exceeds 20 mph (32 km/h)
but remains below 40 mph (64 km/h).
The vehicle is shifted into 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 the 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 will exist immediately.
Feedback To The Driver
The instrument cluster has an SSC icon and the
SSC switch has a lamp that offers feedback to
the driver about the state SSC is in.
The cluster icon and switch lamp will illumi-
nate and remain on solid when SSC is
enabled or activated. These are the normal
operating conditions for SSC.
The cluster icon and switch lamp will flash for
several seconds then extinguish when the
driver pushes the SSC switch but enabled
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.
