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.
