Hill Launch Assist (HLA)
Hill Launch Assist (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 transaxle, Hill Launch Assist (HLA) oper-
ates 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 transaxle, Hill Launch Assist (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 for-
ward gear.
●Hill Launch Assist (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.
●Hill Launch Assist (HLA) does not operate if the parking brake is applied, the
vehicle has not stopped completely, or the clutch pedal is released.
●While Hill Launch Assist (HLA) is operating, the brake pedal may feel stiff
and vibrate, however, this does not indicate a malfunction.
●Hill Launch Assist (HLA) does not operate while the TCS/DSC indicator light
is illuminated.
Refer to Contact Your Toyota Dealer and Have Vehicle Inspected on P. 493.
●Hill Launch Assist (HLA) does not turn off even if the DSC OFF switch is
pressed to turn off the TCS/DSC.
