Brake Assist System (BAS). Hill Start Assist (HSA)
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle's braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous braking
pressure during the stopping sequence, (do not
"pump" the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
| WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydroplaning. The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or dangerous
manner, which could jeopardize the user's safety or
the safety of others. |
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 HSAto
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.
| 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. |
Towing With HSA
HSA will also provide assistance to mitigate roll back
while towing a trailer.
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 leaving your vehicle. Also, be certain to leave the transmission in PARK.
- Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.

Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
- For vehicles equipped with the Driver Information
Display (DID), refer to "Driver Information Display
(DID)" in "Understanding Your Instrument Panel" for
further information.
- If disabling HSA using Uconnect Settings, refer to
"Uconnect Settings" in "Understanding Your Instrument
Panel" for further information.
For vehicles not equipped with the DID, perform the
following steps:
- Center the steering wheel (front wheels pointing
straight forward).
- Shift the transmission into PARK.
- Apply the parking brake.
- Start the engine.
- Rotate the steering wheel slightly more than one-half
turn to the left.
- Push the "ESC Off" button located in the lower switch
bank below the climate control four times within
twenty seconds. The "ESC Off Indicator Light" should
turn on and turn off two times.
- Rotate the steering wheel back to center and then an
additional slighty more than one-half turn to the right.
- Turn the ignition switch to the OFF position and then
back to the ON position. If the sequence was completed
properly, the "ESC Off Indicator Light" will
blink several times to confirm HSA is disabled.
- Repeat these steps if you want to return this feature to
its previous setting.
