436 STARTING AND OPERATING

Ready Alert Braking – If Equipped
Ready Alert Braking 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. When the throttle is released very quickly,
Ready Alert Braking applies a small amount of brake
pressure. This brake pressure will not be noticed by the
driver. The brake system uses this brake pressure to allow
a fast brake response if the driver applies the brakes.
Rain Brake Support – If Equipped
Rain Brake Support 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 only functions when the windshield wipers
are in the LO or HI mode, it does not function in the
intermittent mode. When Rain Brake Support is active, there
is no notification to the driver and no driver interaction is
required.
Hill Descent Control (HDC) — Four-Wheel Drive
Models With MP3023 Two-Speed Transfer Case Only
HDC maintains vehicle speed while descending hills
during off-road driving situations and is available in
4WD LOW range only. To enable HDC, press the HDC
switch.
When HDC is enabled, the HDC icon will be illuminated
in the instrument cluster. HDC will automatically apply
the brakes to control downhill speed to the selected level
when necessary on grades greater than approximately
8%. It will usually not activate on level ground.
The HDC speed may be adjusted by the driver to suit the
driving conditions. The speed corresponds to the trans-
mission gear selected.
HDC operation can be overridden with brake application
to slow the vehicle down below the HDC control speed.
