Hill Launch Assist (HLA)
▼ Hill Launch Assist (HLA)
The HLA functions to assist in
accelerating the vehicle from a stop on
slopes. When releasing the brake pedal
and depressing the accelerator pedal
to accelerate the vehicle from a stop
while on a slope, the function prevents
the vehicle from rolling. The HLA also
operates when reversing on a slope.
The braking force is maintained
automatically after releasing the brake
pedal on a steep slope.
For manual transmission vehicles, the
HLA operates when the vehicle is tilted
rearward with the shift lever in a
forward gear, and operates when the
vehicle is tilted forward with the shift
lever in the R position.
For automatic transmission vehicles,
the HLA operates when the vehicle is
tilted rearward with the selector lever
in a forward gear, and operates when
the vehicle is tilted forward with the
selector lever in the R position.
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.
NOTE
HLA does not operate on a gentle

slope. In addition, the gradient of
the slope on which the system will
operate changes depending on the
vehicle's load.
HLA does not operate if the parking

brake is applied, the vehicle has not
stopped completely, or the clutch
pedal is released.
While HLA is operating, the brake

pedal may feel stiff and vibrate,
however, this does not indicate a
malfunction.
HLA does not operate while the

TCS/DSC indicator light is
illuminated.
Refer to TCS/DSC Indication/
Indicator Light (Turns on) on page
7-55.
HLA does not turn off even if the TCS

OFF switch is pressed to turn off the
TCS.
(Automatic Transmission)

Although the HLA does not operate
during idling stop, the vehicle roll
prevention function operates to
prevent vehicle roll.
