SAFETY125
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.
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 (R) gear).
HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK (P) or NEUTRAL (N).
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows: Úpage 105.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
Ready Alert Braking (RAB)
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.
The Electronic Brake Control (EBC) system will prepare the
brake system for a panic stop.
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.
Traction Control System (TCS)
The 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 vehicle
power to provide enhanced acceleration and stability. A feature
of the TCS, Brake Limited Differential (BLD) functions similarly
to a limited slip differential and controls the wheel spin across
a driven axle. If one wheel on a driven axle is spinning faster
than the other, the system will apply the brake of the spinning
wheel. This will allow more vehicle torque to be applied to the
wheel that is not spinning. BLD may remain enabled even if TCS
and the Electronic Stability Control (ESC) are in reduced modes.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway. Note that TSC cannot
stop all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations
Úpage 94.
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
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 involvement. 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 vehicle. Failure
to follow these warnings can result in a collision or serious
personal injury.
WARNING!
If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released.
In order to avoid rolling down an incline while
resuming acceleration, manually activate the trailer
brake or apply more vehicle brake pressure prior to
releasing the brake pedal.
HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
Failure to follow these warnings can result in a colli -
sion or serious personal injury.
