Rain Brake Support (RBS)
RBS may improve braking performance in wet condi-
tions. It will periodically apply a small amount of brake
pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers
are in LO or HI speed. When RBS is active, there is no
notification to the driver and no driver interaction is
required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full braking
during emergency braking situations. It anticipates
when an emergency braking situation may occur by
monitoring how fast the throttle is released by the
driver. The Electronic Brake Controller (EBC) will pre-
pare the brake system for a panic stop.
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).
