Jeep Wrangler: Electronic Stability Control (ESC) / Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. 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.
The HSA system is designed to mitigate roll
back from a complete stop while on an incline.
If the driver releases the brake while stopped on
an incline, HSA will continue to hold the brake
pressure for a short period...
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...
Other information:
You must press and hold the brake pedal while
shifting out of PARK.
CAUTION!
Shift into or out of PARK or REVERSE only
after the vehicle has come to a complete
stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed...
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze)
to enter the radiator...
