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 resume driving the vehi cle such as by releasing the
clutch pedal with the shift leve r shifted to a position other than the neutral position (manual
transmission vehicle) or depressing the accelerator pedal (automatic transmission vehicle).
WA R N I N G
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 a ccident if the vehicle were to suddenly move.
Operate the brakes appropriatel y 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 vehicle not being held in the stopped position by the
AUTOHOLD function, the vehicle may move un expectedly 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 posi tion by the AUTOHOLD function, the vehicle may
move unexpectedly and result in an accident . Operate the accelerator pedal, brakes, or
steering wheel approp riately 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.

CAUTION
If you stop operating the accelerator pedal before the vehicle starts moving, the force holding
the vehicle in the stopped position may weaken. Firmly depress the brake pedal or depress the
accelerator pedal to accelerate the vehicle.
NOTE
Under the following conditions, a problem with the AUTOHOLD is occurring. Have your
vehicle inspected at an Authorized Mazda Dealer as soon as possible.
A message is indicated on the multi-information display and a warning sound is
activated for about 5 seconds while the AUTOHOLD is operating or when your press
the AUTOHOLD switch.
If you switch the ignition OFF while the AUTOHOLD is operating, the parking brake is
applied automatically to assist you with parking the vehicle.
The AUTOHOLD is canceled when the selector lever/shift lever is shifted to R position
while the vehicle is on level ground, or facing up a hill or grade (as shown below).

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

applied and the AUTOHOLD is
released. In addition, if the parking
brake is released under this condition,
the AUTOHOLD operates to hold the

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 shif
t 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 forwa rd with the selector
lever in the R position.
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 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.

Mazda3_8HE9-EA-18K_Edition3 2018-11-21 14:31:58

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.
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 TCS/DSC Indication/Indicator
Light (Turns on) on page 7-31.
HLA does not turn off even if the DSC
OFF switch is pressed to turn off the
TCS/DSC.

Mazda Radar Cruise
Control (MRCC) (Manual
Transmission)
*
▼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 sufficient distance
between the vehicles.
Also refer to the following before using
the MRCC.
Front radar sensor (page 4-202)
WA R N I N G
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
sufficiently 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 traffic is heavy and there is
insufficient space between vehicles.
 Roads where frequent and repetitive
acceleration and deceleration occur
(Driving under these conditions using the
MRCC system 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).

NOTE
When the MRCC is operating, Distance & Speed Alert (DSA), and Smart Brake Support
(SBS) also turns on automatically.
Turning on the system
1. CANCEL switch
2. RES switch
3. MRCC switch

When the MRCC switch is pressed once, the MRCC system turns on, and the MRCC
standby indication (white) turns on and the vehicle speed and t he distance between the
vehicles while in headwa y control can be set.
In addition, the MRCC system dis play indication is displayed on the multi-information
display and the active drivin g display at the same time.
NOTE
If the ignition is switched off while the MRCC system is operating, the system will be
operable when the ignition is switched ON the next time.
