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.
• Park brake must be off.
• Driver door must be closed.
• 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 transmission is in
PARK or NEUTRAL. For vehicles equipped with a
manual transmission, if the clutch is pressed, HSA will
remain active.
operating conditions), the transmission may use second
gear (rather than first gear) during launches, to mini-
mize wheel slippage.
• SAND: For off-road driving or use on surfaces with poor
traction, such as dry sand. The transmission is set to
provide maximum traction.
• MUD: For off-road driving or use on surfaces with poor
traction, such as roads covered by mud or wet grass.
• ROCK (Trailhawk only): This mode is only available in
4WD LOW range. The device sets the vehicle to maxi-
mize traction and allow the highest steering capacity for
off-road surfaces. This mode gives you the maximum
performance off-road. Use for low speed obstacles such
as large rocks, deep ruts, etc.
NOTE:
• Rock mode is only available on the vehicles equipped
with the Off-Road package.
• Activate the Hill Descent Control for steep downhill
control. See “Electronic Brake Control System” in this
section for further information.POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that reduces
assist or prevents the vehicle from providing assist, you
will still have the ability to steer the vehicle manually.
