Mazda 2: 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 shift lever is in
the reverse (R) position, and on an upward
slope when the shift 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
page 4-37 .
- Hill Launch Assist (HLA) does not
turn off even if the DSC OFF switch
is pressed to turn off the TCS/DSC.
- (Automatic Transaxle)
Although the Hill Launch Assist
(HLA) does not operate during idling
stop, the vehicle roll prevention
function operates to prevent vehicle
roll.
