Hill-Start Assist Control (HAC)
Hill-Start Assist Control helps prevent
the vehicle from rolling backwards
when starting a vehicle from a stop
on a hill. The system operates the
brakes automatically for approximately
2 seconds (maximum of 5 seconds
when the accelerator pedal is slightly
depressed during HAC operation) and
releases the brake after 2 seconds or
when the accelerator pedal is depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off
an incline. Hill-Start Assist Control
activates only for approximately 2
seconds (maximum of 5 seconds
when the accelerator pedal is slightly
depressed during HAC operation).
Information
ś
Hill-Start Assist Control does not
operate when the gear is shifted to P
(Park) or N (Neutral).
ś
Hill-Start Assist Control activates even
when the ESC (Electronic Stability
Control) is off. However, it does not
activate, when ESC does not operate
normally.
Trailer Stability Assist (TSA)
Trailer stability assist is operated as a
vehicle stability control system. The
Trailer stability assist system stabilizes
the vehicle and trailer when the trailer
sways or oscillates. There are various
reasons making vehicle sway and
oscillate. In most case it happens at high
speed however, if the trailer is affected
by crosswinds, buffeting, and improper
overloading, it may also be a risk of sway.
Factors of swaying such as:
-
High speed
-
Strong crosswinds
-
Improper overloading
-
Sudden controlling of steering wheel
-
Uneven road
Trailer stability assist system
continuously analyzes the vehicle
and trailer instability. When the
Trailer stability assist system detects
some sway, the brakes are applied
automatically to stabilize the vehicle
on the front wheel. However, if it is
not enough to stabilize, the brakes are
applied on all wheels automatically and
engine power is properly reduced. When
the vehicle is stable from swaying, trailer
stability assist system does not operate.
