Resume driving information
If you do not resume driving within a few sec onds after the vehicle ahead starts moving, the
multi-information display vehicle-ahead indicat ion flashes to urge the driver to resume
driving.
▼ Cruise Control Function
While this function is operating, the
headway control operation is canceled and
only the cruise contro
l function operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise control function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
Roads with sharp curves and where
vehicle traffic is heavy and there is
insufficient space between vehicles.
(Driving under these conditions using the
cruise control function is not possible)
Steep down slopes (Set speed may be
exceeded because sufficient engine
braking cannot be applied)
Slippery roads such as ice or snow-bound
roads (Tires could spin causing you to
lose vehicle control)
Always drive carefully:
The warnings and brake control will not
operate after the headway control function
is canceled and the system is switched to
only the cruise control function. Depress
the brake pedal to decelerate according to
the surrounding conditions while keeping a
safer distance from the vehicle ahead and
always driving carefully.

Traffic Jam Assist (TJA)*
The TJA is a system which consists of a headway control function and a steering assist
function for reducing driver fatigue during traffic jams when driving on expressways or
highways.
This system performs headway control to maintain a constant distance between your vehicle
and a vehicle ahead at a preset vehicle speed without you having to use the accelerator or
brake pedal. Even further, with the steering assist function, when vehicle lane lines are
detected, the function assists the driver in k eeping the vehicle within the lane lines. If lane
lines are not detected, the function provides th e driver driving assistance in keeping the
vehicle along the motion path with the vehicle ahead.
WA R N I N G
Do not rely completely on TJA:
The TJA is not an automated driving system. In addition, the functions have limitations. Do
not rely completely on the system and always stay on course using the steering wheel.
Set a vehicle speed within the speed limit acco rding to the road conditions and the weather
conditions.
The TJA may not be able to detect a vehicle ahead depending on the type of vehicle ahead
and its conditions, the weather conditions, and the road conditions. Add\
itionally, the
system might be unable to decelerate suffic iently if a vehicle ahead applies the brakes
suddenly, another vehicle cuts into the driving lane, or the difference in vehicle speed
between your vehicle and the vehicle ahead is larger, which could result in an accident.
Check the surrounding conditions and always drive carefully while keeping a safe distance
from vehicles ahead and on-coming vehicles.
For the purposes of safety, switch the TJA off when it is not being used.
Leaving the TJA turned on when it is not in us e is dangerous as it could operate unexpectedly,
resulting in an accident.
Do not use the TJA under the following conditions. Otherwise, it may result in an accident.
General roads other than expressways or high ways (Driving under these conditions using
the TJA is not possible.)
Roads with sharp curves and where vehicle tr affic is heavy with insufficient space between
vehicles, or roads where frequent and repet itive acceleration and deceleration occur
(Driving under these conditions using the TJA is not possible).

When entering and exiting interchanges, servic e 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 a ccelerate to the set speed).
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.)
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.)
Two-wheeled vehicles such as mo torcycles or bicycles are ahead.
Slopes with a steep gradient (The vehicle ahea d 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.)
Driving under bad weather conditions (rain, fog, and snow).
Tires of a
different
specified size are used, such as a temporary spare tire.
Tires with insufficient tread are used.
The tire pressures are not adjusted to the
specified pressure.
The vehicle is being used to tow a camper or boat trailer.
Tire chains are used.
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.
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
TJA off, apply the parking brake, and then sh ift the selector lever to the P position.
CAUTION
Heed the following cautions so th at the TJA can operate normally.
Turn the system off when the vehicle is running on a chassis roller.
Do not modify the vehicle's suspensions.
Always use wheels of the specified size for th e front and rear wheels. Consult an Authorized
Mazda Dealer for tire replacement.
NOTE
The headway control does not detect the following as physical objects.

Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS)
*
The LAS & LDWS alerts the driver that the vehicle may be deviating from its lane and it
provides steering assistance to help the driver stay within the vehicle lanes.
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 activating a lane departure warning sound,
vibrating the steering wheel, and indicating an alert in the display. Use the system when you
drive the vehicle on roads with white (yello w) lines such as expressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-256.

Do not rely completely on the LAS & LDWS:
The LAS & LDWS is not an automatic 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.
The detection ability of the LAS & LDWS is limited. Always stay on course using the steering
wheel and drive with care.
Do not use the LAS & LDWS in the following cases:
The system may not operate adequately accordin g to the actual driving conditions, resulting
in an accident.
