You start to release the clutch pedal with
the shift lever shifted to a position other
than the neutral position
•(Automatic transaxle vehicle)
•The accelerator pedal is depressed.
•The vehicle tilts rearward or the
selector lever is shifted to the R
position on level ground.
NOTE
•If the electric parking brake (EPB)
switch is pulled while the AUTOHOLD

automatically applie d. Because the
AUTOHOLD is restored when releasing
the parking brake, the hold on the
brakes by AUTOHOLD function
resumes.

Hill Launch Assist (HLA)
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. T he braking force is
maintained automatically after the brake
pedal is released on a steep grade.
For vehicles with a manual transaxle,
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,
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.
WA R N I N G
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 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 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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-30.
•HLA does not turn of f even if the TCS
OFF switch is pressed to turn off the
TCS.

Roads where frequent and repetitive accelerati on and deceleration occur (Driving under
these conditions using the MRCC with Stop & Go function system is not possible).
 When entering and exiting interchanges, servic e areas, and parking areas of highways (If
you exit a highway while headway control is in use, the vehicle ahead will no longer be
tracked and your vehicle may accelerate to the set speed).
 Slippery roads such as ice or snow-bound roads (Tires could spin causing you to lose vehicle
control, or the stop hold control may not operate.)
 Long, descending slopes (to maintain distance between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
 Slopes with a steep gradient (The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold control, and it may accelerate suddenly after it
starts moving.)
For safety purposes, switch the MRCC with Stop & Go function system off when it is not being
used.
Do not get out of the vehicle while the stop hold control is operating:
Getting out of the vehicle while the stop hold co ntrol is operating is dangerous as the vehicle
may move unexpectedly and result in an accident. Before getting out of the vehicle, switch the
MRCC with Stop & Go function system off, shift the selector lever to the P position, and apply
the parking brake.
CAUTION
If your vehicle is towed or you are towing something, switch the MRCC with Stop & Go
function system off to prevent a mis-operation.
NOTE
•The MRCC with Stop & Go function system does not detect the following as physical
objects.
•Vehicles approaching in the opposite direction
•Pedestrians
•Stationary objects (stopped vehicles, obstructions)
•If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
•During headway control travel, do not set the system for detection of two-wheeled
vehicles such as motorcycles and bicycles.
•Do not use the MRCC with Stop & Go function system under conditions in which close
proximity warnings are frequently activated.

NOTE
•The distance-between-vehicles differs depending on the vehicle speed, and the slower the
vehicle speed, the shorter the distance.
•When the ignition is switched to ACC or OFF and then the engine is started again, the
system automatically sets the distance-between-vehicles to the previous setting.
How to change the set vehicle speed
To accelerate/decelerate using the SET
switch
When you press the SET
switch, the
vehicle accelerates and when you press the
SET
switch, it decelerates.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET switch four
times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To increase speed using accelerator
pedal
Depress the accelerator pedal and press
and release the SET
switch or SET

ahead, acceleration continues until
reaching the set vehicle speed. For the set
vehicle speed, check the set vehicle speed
indication in the display.
•While depressing the accelerator pedal,
the color of the MRCC with Stop & Go
function indication changes from green
to white.
