Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is a system which provides
advice for maintaining the appropriate
distance between vehicles and
notifies
the driver of the recommended, safe
distance to maintain with a vehicle
ahead. The system measures the
distance between your vehicle and a
vehicle ahead while the vehicle speed
is about 30 km/h (19 mph) or faster. If
the distance between your vehicle and
a vehicle ahead is close, the system
alerts the driver of a possible collision
using an indication on the display.
WARNING
Do not rely completely on the DSA :
The ability of the system to detect a
vehicle ahead is limited depending on
the type of vehicle ahead, weather
conditions, or tra ffic conditions. In
addition, the system is not for
maintaining the distance between your
vehicle and a vehicle ahead. If you
neglect to operate the accelerator and
brake pedals correctly, it could lead to
an accident. Always check the safety of
the surrounding area and depress the
brake pedal or accelerator pedal while
keeping a safe distance from vehicles
ahead or on-coming vehicles.

short.
A vehicle suddenly comes close,
such as by cutting into your lane.
To prevent incorrect operation of the
system, use tires of the same
specified size, manufacturer, brand,
and tread pattern on all four wheels.
In addition, do not use tires with
significantly di fferent wear patterns
or tire pressures on the same vehicle
(Including the temporary spare tire).
If the battery power is weak, the
system may not operate correctly.
When driving on roads with little
tra ffic and few vehicles ahead or
obstructions for the front radar
sensor to detect, “Safety and Driver
Support Systems Temporarily
Disabled. Front Radar Obscured.
Drive Safely” may be temporarily
displayed, however, this does not
indicate a problem.
The radar sensors are regulated by
the relevant radio wave laws of the
country in which the vehicle is
driven. If the vehicle is driven
abroad, authorization from the
country in which the vehicle is driven
may be required.

▼Towing Description
We recommend that towing be done
only by an Authorized Mazda Dealer
or a commercial tow-truck service.

Proper lifting and towing are necessary
to prevent damage to the vehicle.
Particularly when towing an AWD
vehicle, where all the wheels are
connected to the drive train, proper
transporting of the vehicle is absolutely
essential to avoid damaging the drive
system. Government and local laws
must be followed.
1. Wheel dollies

A towed FWD vehicle should have its
drive wheels (front wheels)
off the
ground. If excessive damage or other
conditions prevent this, use wheel
dollies.

When towing a FWD vehicle with the
rear wheels on the ground, release the
parking brake.
Refer to Electric Parking Brake (EPB) on
page 4-66.

A towed AWD vehicle must have all its
wheels off the ground.
WARNING
Always tow an AWD vehicle with all
four wheels
off the ground:
Towing an AWD vehicle with either the
front or rear wheels on the ground is
dangerous as the drive train could be
damaged, or the vehicle could trail
away from the tow truck and cause an
accident. If the drive train has been
damaged, transport the vehicle on a
fl atbed truck.
CAUTION

Do not tow the vehicle pointed
backward with driving wheels on the
ground. This may cause internal
damage to the transmission.
