Hill Launch Assist (HLA)

HLA is a function which assists the driver
in accelerating from a stop while on a
slope. When the driver releases the brake
pedal and depresses the accelerator pedal
while on a slope, the function prevents the
vehicle from rolling. The braking force is
maintained automatically after the brake
pedal is released on a steep grade.
For vehicles with a manual transmission,
HLA operates on a downward slope when
the shift lever is in the reverse (R)
position, and on an upward slope when the
shift lever is in a position other than the
reverse (R) position.
For vehicles with an automatic
transmission, HLA operates on a
downward slope when the selector lever is
in the reverse (R) position, and on an
upward slope when the selector lever is in
a forward gear.
WARNING
Do not rely completely on HLA:
HLA is an auxiliary device for accelerating
from a stop on a slope. The system only
operates for about 2 seconds and
therefore, relying only on the system, when
accelerating from a stop is dangerous
because the vehicle may move (roll)
unexpectedly and cause an accident.
The vehicle could roll depending on the
vehicle's load or if it is towing something. In
addition, for vehicles with a manual
transmission, the vehicle could still roll
depending on how the clutch pedal or the
accelerator pedal is operated.
Always confirm the safety around the
vehicle before starting to drive the vehicle.
