Mazda 3 Owners Manual: 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) 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 transaxle, Hill Launch Assist (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 Hill Launch
Assist (HLA):
Hill Launch Assist (HLA) is an auxiliary
device for accelerating from a stop
on a slope. The system only operates
for about two 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 transaxle, the vehicle could still roll depending on how the clutch pedal or the accelerator pedal is operated. Always confi rm the safety around the vehicle before starting to drive the vehicle. |
NOTE
- 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 Warning/Indicator Lights on .
- Hill Launch Assist (HLA) does not turn off even if the DSC OFF switch is pressed to turn off the TCS/DSC.
Brake Assist
During emergency braking situations
when it is necessary to depress the brake
pedal with greater force, the brake assist
system provides braking assistance, thus
enhancing braking performance.
