130 SAFETY
Enabling SSC
SSC is enabled by pushing the SSC switch, but
the following conditions must also be met to
enable SSC:
Driveline is in 4L Range

Vehicle speed is below 5 mph (8 km/h)

Park 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

PARK (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 driver-selected 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
