290 SAFETY
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) (HDC exits immediately).
HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the
HDC switch has an indicator light, which offers
feedback to the driver about the state HDC is in.
The cluster icon and switch indicator light will
illuminate and remain on solid when HDC is
enabled or activated. This is the normal oper-
ating condition for HDC.
The cluster icon and switch indicator light will
flash for several seconds then extinguish
when the driver pushes the HDC switch but
enable conditions are not met.
The cluster icon and switch indicator light will
flash for several seconds then extinguish
when HDC disables due to excess speed.
The cluster icon and switch indicator light will
flash when HDC deactivates due to over-
heated brakes. The flashing will stop and
HDC will activate again once the brakes have
cooled sufficiently.
Hill Start Assist (HSA)
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. If the driver does
not apply the throttle before this time expires,
the system will release brake pressure and the
vehicle will roll down the hill as normal.
The following conditions must be met in order
for HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed. (If the doors
are attached, then the door must be closed.
If the doors are detached then the driver's
seat belt must be buckled.)
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in
forward gear; vehicle backing uphill is in
REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans-
mission is in PARK or NEUTRAL. For vehicles
equipped with a manual transmission, if the
clutch is pressed, HSA will remain active.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for
maintaining a safe vehicle speed.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA
is not a substitute for active driving involve-
ment. It is always the driver’s responsibility to
be attentive to distance to other vehicles,
people, and objects, and most importantly
brake operation to ensure safe operation of
the vehicle under all road conditions. Your
complete attention is always required while
driving to maintain safe control of your vehi-
cle. Failure to follow these warnings can
result in a collision or serious personal injury.
