Jeep Wrangler: Electronic Stability Control (ESC) / Selec-Speed Control (SSC) — If Equipped
SSC is intended for off-road
driving in
4WD Low only. SSC maintains vehicle
speed by actively controlling engine
torque and brakes.
SSC has three states:
- Off (feature is not enabled and will not
activate)
- Enabled (feature is enabled and ready but
activation conditions are not met, or driver
is actively overriding with brake or throttle
application)
- 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:
- 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.
- Your 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 = 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 transmission.
While actively controlling SSC, the transmission
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 illuminate
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.
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.
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...
TCS monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected,
the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce engine power
to provide enhanced acceleration and stability...

Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog lights that are
lighter and less susceptible to stone breakage than glass headlights.
Plastic is not as scratch resistant as glass and therefore different lens
cleaning procedures must be followed...
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control for cruising at a constant
preset speed.
Adaptive Cruise Control (ACC) for maintaining
a set distance between you and the vehicle
ahead using Fixed Speed Cruise Control to
automatically adjust the preset speed...
