256 SAFETY
Enabling SSC
SSC is enabled by pushing the SSC switch, but the
following 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:

The driver releases the throttle.

The driver releases the brake.

The transmission is in any selection other than
PARK.

The 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 appro -
priately 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 aggressive -
ness.
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.

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).
