2021 MAZDA MODEL 3 HATCHBACK parking brake

AUTOHOLD
▼AUTOHOLD
The AUTOHOLD function automatically holds the vehicle stopped, even if you take
your foot
off the brake pedal. This function can be best used while stopped in
traffic
or at a traffic light. The brakes are released when you start driving the vehicle.
WARNING
Do not rely completely on the AUTOHOLD function:
The AUTOHOLD function is only designed to assist the brake operation while the
vehicle is stopped. Neglecting to operate the brakes and relying only on the
AUTOHOLD system is dangerous and could result in an unexpected accident if the
vehicle were to suddenly move. Operate the brakes appropriately in accordance
with the road and surrounding conditions.
Do not release your foot from the brake pedal while the vehicle is stopped on a
steep grade:
Because there is a possibility of the vehicl
e not being held in the stopped position by
the AUTOHOLD function, the vehicle may move unexpectedly and result in an
accident.
Do not use the AUTOHOLD function on slippery roads such as icy or
snow-covered roads, or unpaved roads:
Even if the vehicle is held in the stopped position by the AUTOHOLD function, the
vehicle may move unexpectedly and result in an accident. Operate the accelerator
pedal, brakes, or steering wheel appropriately as necessary.
Immediately depress the brake pedal in the following cases:
Because the AUTOHOLD function is canceled forcibly, the vehicle may move
unexpectedly and result in an accident.
 “Depress Brake Pedal. Brake Hold Disabled” is displayed in the multi-information
display and the warning sound is activated at the same time.
Always apply the parking brake when parking the vehicle:
Not applying the parking brake when parking the vehicle is dangerous as the vehicle
may move unexpectedly and result in an accident. When parking the vehicle, shift
the selector lever to the P position (automatic transmission vehicle) and apply the
parking brake.

Hill Launch Assist (HLA)
▼ Hill Launch Assist (HLA)
The HLA functions to assist in
accelerating the vehicle from a stop on
slopes. When releasing the brake pedal
and depressing the accelerator pedal
to accelerate the vehicle from a stop
while on a slope, the function prevents
the vehicle from rolling. The HLA also
operates when reversing on a slope.
The braking force is maintained
automatically after releasing the brake
pedal on a steep slope.
For manual transmission vehicles, the
HLA operates when the vehicle is tilted
rearward with the shift lever in a
forward gear, and operates when the
vehicle is tilted forward with the shift
lever in the R position.
For automatic transmission vehicles,
the HLA operates when the vehicle is
tilted rearward with the selector lever
in a forward gear, and operates when
the vehicle is tilted forward with the
selector lever in the R position.
WARNING
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 2
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 transmission, the
vehicle could still roll depending on
how the clutch pedal or the accelerator
pedal is operated.
When Driving
Brake

Mazda3_8JM2-EA -20H_Edition1_new 2020-7-10 17:21:34

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 sti ff and vibrate,
however, this does not indicate a
malfunction.
HLA does not operate while the
TCS/DSC indicator light is
illuminated.
Refer to TCS/DSC Indication/
Indicator Light (Turns on) on page
7-32.
HLA does not turn o ff even if the
DSC OFF switch is pressed to turn off
the TCS/DSC.

Mazda Radar Cruise
Control (MRCC) (Manual
Tra n s m i s s i o n )
*
▼Mazda Radar Cruise Control
(MRCC)
The MRCC system is designed to
maintain headway control*1 with a
vehicle ahead according to your
vehicle's speed using a front radar
sensor to detect the distance to the
vehicle ahead and a preset vehicle
speed without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and
the vehicle ahead detected by the
MRCC system.
Additionally, if your vehicle starts
closing in on the vehicle ahead such as
if the vehicle ahead brakes suddenly, a
warning sound and a warning
indication in the display are activated
simultaneously to alert you to maintain
a su fficient distance between the
vehicles.
Also refer to the fo llowing before using
the MRCC.
Front radar sensor (page 4-207)
WARNING
Do not rely completely on the MRCC :
The MRCC system has detection
limitations depending on the type of
vehicle ahead and its conditions, the
weather conditions, and the road
conditions. Additionally, the system
may be unable to decelerate
su fficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the
brakes suddenly or another vehicle
cuts into the driving lane, which could
result in an accident.
Always drive carefully and verify the
surrounding conditions and depress
the brake pedal or accelerator pedal
while keeping a safe distance from
vehicles ahead or on-coming vehicles.
Do not use the MRCC system in the
following locations. Using the MRCC
system at the following locations may
result in an unexpected accident:
 General roads other than highways
(Driving under these conditions
using the MRCC system is not
possible.)
 Roads with sharp curves and where
vehicle tra ffic is heavy with
insu fficient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the MRCC is
not possible.)
 When entering and exiting
interchanges, service 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.)
