Mazda 3 Hatchback (2022 year). Manual in english - page 19

 

 

¾

When entering and exiting
interchanges, service areas, and
parking areas of expressways (If you
exit an expressway while headway
control is in use, the vehicle ahead
will no longer be tracked and your
vehicle may accelerate to the set
speed).

¾

Slippery roads such as icy or
snow-covered roads (Tires could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)

¾

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.)

¾

Two-wheeled vehicles such as
motorcycles or bicycles are ahead.

¾

(Automatic transmission vehicle)

Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly, your vehicle may slip while
stopped by the stop hold control, or
it may accelerate suddenly after it
starts moving.)

¾

Driving under bad weather
conditions (rain, fog, and snow).

¾

The vehicle is driven on slippery
roads such as icy or snow-covered
roads and unpaved roads (Tires
could spin causing you to lose
vehicle control, or the stop hold
control may not operate.)

¾

Tires of a different specified size are
used, such as a temporary spare tire.

¾

Tires with insufficient tread are used.

¾

The tire pressures are not adjusted to
the specified pressure.

¾

The vehicle is being used to tow a
camper or boat trailer.

¾

Tire chains are used.

¾

The vehicle is driven on roads with
lane lines other than white (yellow)
lines, such as an expressway.

Do not get out of the vehicle while
the stop hold control is operating.
(Automatic transmission vehicle)

Getting out of the vehicle while the
stop hold control is operating is
dangerous as the vehicle may move
unexpectedly and result in an accident.
Before getting out of the vehicle,
switch the TJA off, apply the parking
brake, and then shift the selector lever
to the P position.

CAUTION

Turn the system off when the vehicle is
running on a chassis roller.
Heed the following cautions so that
the TJA can operate normally.

¾

Turn the system off when the vehicle
is running on a chassis roller.

¾

Do not modify the vehicle's
suspensions.

¾

Always use wheels of the specified
size for the front and rear wheels.
Consult an Authorized Mazda Dealer
for tire replacement.

NOTE

x

If a vehicle ahead is traveling at an
extremely low speed, the system may
not detect it correctly.

x

If there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the TJA.

x

Do not use the TJA under conditions
in which close proximity warnings
are frequently activated.

x

If it is necessary to accelerate for a
lane change or the vehicle ahead
brakes suddenly causing you to close
in on the vehicle rapidly, accelerate
using the accelerator pedal or
decelerate using the brake pedal
depending on the conditions.

x

While the TJA is in use, any intended
engine braking does not occur even
if you shift the shift lever (manual
transmission) or the selector lever
(automatic transmission). If
deceleration is required, lower the
vehicle speed setting or depress the
brake pedal.

x

While braking by the TJA control is
operating, you might hear an
operation sound, however, this does
not indicate a problem.

x

The brake lights turn on while
braking by the TJA control is
operating, however, they may not
turn on while the vehicle is on a
down slope at the set vehicle speed
or traveling at a constant speed and
following a vehicle ahead.

x

Under the following conditions, the
TJA may not be able to detect white
(yellow) lines or vehicles ahead
correctly and the TJA may not
operate normally.

of the vehicle due to soiling or fog.

x

The white (yellow) lane lines are
less visible because of dirt or paint
flaking.

x

White (yellow) lane lines or
vehicles ahead are less visible
because of bad weather (rain, fog,
or snow).

x

The vehicle is driven on a
temporary lane or section with a
closed lane resulting from
construction where there might be
multiple white (yellow) lane lines,
or they are interrupted.

x

The camera picks up an obscure
line, such as a temporary line being
used for construction, or because
of shade, unmelted snow, or
grooves filled with water.

x

The road surface is wet and shiny
after rain, or there are puddles on
the road.

x

Heavy luggage is loaded in the
trunk/luggage compartment or on
the rear seat causing the vehicle to
tilt.

x

Lane-keep Assist System

(LAS)

*

Lane-keep Assist System (LAS)

The LAS provides steering assistance to
help the driver stay within the vehicle
lane if the vehicle might be deviating.
The forward sensing camera (FSC)
detects the white lines (yellow lines) of
the vehicle lane in which the vehicle is
traveling and if the system determines
that the vehicle may deviate from its
lane, it operates the electric power
steering to assist the driver’s steering
operation. The system also alerts the
driver by displaying an alert on the
multi-information display. Use the
system when you drive the vehicle on
roads with white (yellow) lines such as
expressways and highways.

1. Forward sensing camera (FSC)

WARNING

Do not rely completely on the LAS:

¾

The LAS is not an automated driving
system. In addition, the system is not
designed to compensate for a
driver’s lack of caution, and
over-reliance on the system could
lead to an accident.
