Hill Launch Assist (HLA)

WARNING

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.

Do not drive with worn disc pads:

Driving with worn disc pads is

dangerous. The brakes could fail and

cause a serious accident. As soon as

you hear a screeching noise consult an

Authorized Mazda Dealer.

Brake Assist

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.

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.

When the brake pedal is depressed hard or

depressed more quickly, the brakes apply

more ﬁrmly.

NOTE

^ꢀyꢀWhen the brake pedal is depressed hard

or depressed more quickly, the pedal

will feel softer but the brakes will apply

more ﬁrmly. This is a normal effect of

the brake assist operation and does not

indicate a malfunction.

^ꢀyꢀWhen the brake pedal is depressed

hard or depressed more quickly, a

motor/pump operation noise may be

heard. This is a normal effect of the

brake assist and does not indicate a

malfunction.

^ꢀyꢀThe brake assist equipment does not

supersede the functionality of the

vehicle's main braking system.

Brake

NOTE

WARNING

^ꢀyꢀHill 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.

^ꢀyꢀHill Launch Assist (HLA) does not

operate if the parking brake is applied,

the vehicle has not stopped completely,

or the clutch pedal is released.

^ꢀyꢀWhile Hill Launch Assist (HLA) is

operating, the brake pedal may feel

stiff and vibrate, however, this does not

indicate a malfunction.

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.

^ꢀyꢀHill Launch Assist (HLA) does not

operate while the TCS/DSC indicator

light is illuminated.

^ꢀRefer to Warning/Indicator Lights on

page 4-20.

^ꢀyꢀHill Launch Assist (HLA) does not

turn off even if the DSC OFF switch is

pressed to turn off the TCS/DSC.

Always conꢂrm the safety around the

vehicle before starting to drive the

vehicle.

Smart City Brake Support (SCBS)^*

The Smart City Brake Support (SCBS) system is designed to reduce damage in the event

of a collision by operating the brake control (SCBS brake) when the system's laser sensor

detects a vehicle ahead and determines that a collision with a vehicle ahead is unavoidable.

It may also be possible to avoid a collision if the relative speed between your vehicle and a

vehicle ahead is less than about 15 km/h (9.3 mph).

In addition, when the driver depresses the brake pedal while the system is in the operation

range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied ﬁrmly and quickly to

assist. (Brake Assist (SCBS brake assist))

Laser sensor

WARNING

Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safe

driving:

The Smart City Brake Support (SCBS) system cannot compensate for unsafe and reckless

driving, excessive speed, tailgating (following another vehicle too closely), and driving on

slippery roads such as wet, snowy, and icy roads (reduced tire friction and road contact

because of water on the road surface). You can still have an accident.

Do not rely completely on the Smart City Brake Support (SCBS) system:

ꢀ¾ꢀ

The Smart City Brake Support (SCBS) system is only designed to reduce damage in the

event of a collision. Over reliance on the system leading to the accelerator pedal or

brake pedal being mistakenly operated could result in an accident.

ꢀ¾ꢀ

The Smart City Brake Support (SCBS) is a system which operates in response to a

vehicle ahead. The system may not be able to detect or react to 2-wheeled vehicles or

pedestrians.

ꢀ¾ꢀ

The laser sensor for the Smart City Brake Support (SCBS) system is installed near the

rearview mirror. To assure the correct operation of the Smart City Brake Support

(SCBS), heed the following cautions.

ꢀ

¾

Do not apply stickers to the surface of the windshield near the laser sensor

(including transparent stickers). Otherwise, the laser sensor may not be able to

detect vehicles ahead which could result in an accident.

ꢀ

¾

Do not apply coating agent to the windshield. Otherwise, the laser sensor may not

be able to detect vehicles or obstructions in front which could result in an accident.

Do not disassemble the laser sensor.

If cracks or damage caused by ꢃying gravel or debris is visible near the laser sensor,

stop using the Smart City Brake Support (SCBS) system immediately and have your

vehicle inspected by an Authorized Mazda Dealer. If the vehicle continues to be

driven with cracks or scratch marks left on the windshield near the laser sensor, the

system may operate unnecessarily and cause an unexpected accident.

CAUTION

ꢀ¾ꢀ

When driving oꢀ-road in areas where there is grass or forage, it is recommended that the

Smart City Brake Support (SCBS) system be turned oꢀ.

ꢀ¾ꢀ

Always use tires for all wheels that are of the speciꢂed size, and the same manufacturer,

brand, and tread pattern. In addition, do not use tires with signiꢂcantly diꢀerent wear

patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not

operate normally.

ꢀ¾ꢀ

The laser sensor includes a function for detecting a soiled windshield and informing the

driver, however, depending on the conditions, it may not detect plastic shopping bags, ice

or snow on the windshield. In such cases, the system cannot accurately determine a vehicle

ahead and may not be able to operate normally. Always drive carefully and pay attention

to the road ahead.

NOTE

^ꢀyꢀThe Smart City Brake Support (SCBS) system will not operate if the driver is deliberately
