Secondary CollisionReduction
*
The Secondary Collision Reduction
reduces secondary damage by
decelerating the vehicle when it is
damaged in a collision to the extent
that the airbags are deployed while
driving.
If a collision occurs to the extent that
the airbags are deployed while driving,
the hazard warning lights flash to alert
surrounding vehicles and the brakes
are controlled to reduce damage in the
event of a collision with an obstruction
or other object.
Warnings and Cautions
for Using the Secondary Collision Reduction
WARNING
Do not rely completely on the
Secondary Collision Reduction.
The Secondary Collision Reduction
may not operate normally depending
on various conditions such as the
accident condition, component part
damage condition, target object
condition, weather conditions, or
traffic conditions. Do not rely
completely on the system and make
it your responsibility as a driver to
drive the vehicle.
 The functions of the Secondary
Collision Reduction have limitations.
If you neglect to operate the brake
and accelerator pedals correctly, it
could result in serious injury.

How to Use the
Secondary Collision Reduction
When the Secondary Collision
Reduction operates
The Secondary Collision Reduction
operates if the vehicle is damaged in a
collision to the extent that the airbags
are deployed while driving.

When the Secondary Collision
Reduction operates, the system
controls and applies the brakes until
the vehicle stops. In addition, the
hazard warning lights continue to flash.
After the vehicle stops, the parking
brake is applied by the Electric Parking
Brake (EPB).
NOTE
The brake lights turn on while the
brakes are operating by the system
control.
If there is a malfunction with the
electric parking brake (EPB), the
brakes are released by the system
control after the vehicle is stopped.
The settings for the Secondary
Collision Reduction system differ
depending on the grade/specification-separate equipment.
Secondary Collision Reduction is
disabled
If any of the following conditions is
met, the Second ary Collision
Reduction is canceled.
A certain period of time has passed
since the system operated.
After stopping the vehicle, the
accelerator pedal is strongly
depressed 3 times.
The parking brake is released after
the Electric Parking Brake (EPB)
operates.
NOTE
If the driver's brake pedal depression
force is stronger than the system's
brake control, the driver's brake
operation takes priority.
Flashing of the hazard warning lights
by the system control is canceled
when any of the following operations
is performed.
Hazard warning light switch is
pressed.
Vehicle power is switched OFF.

be restricted and the vehicle may not
be able to be driven at the set speed.
Refer to Mazda intelligent Drive
Select (Mi-Drive) on page 5-95.
The accelerator pedal operation
takes priority during constant speed
driving. When you release your foot
from the accelerator pedal, the
vehicle returns to constant speed
driving at the set speed.
(Vehicles with Mazda Radar Cruise
Control with Stop & Go function
(MRCC with Stop & Go function))
If the distance between vehicles
control is disabled using the Mazda
Connect, the system switches to the
cruise control. At this time, the
MRCC switch functions as the cruise
control switch.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
If the vehicle power is switched OFF
while the distance between vehicles
control is disabled, the distance
between vehicles control is enabled
automatically the next time the
vehicle power is switched ON.
The system may not be able to
maintain the set speed depending
on the road conditions such as steep
up or down slopes.
When the vehicle speed is less than
20 km/h (12 mph), the cruise
control is canceled. If you want to

cruise control.
The brake lights turn on while the
brakes are operating by the cruise
control.
The cruise control cannot be
canceled while driving in manual
shift mode (selector lever shifted
from the D to M position).
Therefore, engine braking does not
work even if you shift down to a
lower gear. If deceleration is
required, lower the set vehicle speed
or depress the brake pedal.

Winter Driving
Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
check the following:
Have the proper ratio of antifreeze in
the radiator.
Refer to Inspecting the Coolant on
page 9-14.
Inspect the battery and its cables.
Cold reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
9-18).
Inspect the ignition system for
damage and loose connections.
Use washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid
(page 9-17).
When driving on ice or in water, snow,
mud, sand, or similar hazards:
Be cautious and allow extra distance
for braking.
Avoid sudden braking and sudden
maneuvering.
Do not pump the brakes. Continue
to press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 5-84.
If you get stuck, select a lower gear
and accelerate slowly. Do not spin
the rear wheels.
For more traction in starting on
slippery surfaces such as ice or
packed snow, use sand, rock salt,
chains, carpeting, or other nonslip
material under the rear wheels.
NOTE
Remove snow before driving. Snow
left on the windshield is dangerous
as it could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windshield.
Never use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
Drive slowly. Braking performance
can be adversely affected if snow or
ice adheres to the brake
components. If this situation occurs,
drive the vehicle slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to
normal.

Do not connect a hydraulic
trailer-brake system to your vehicle's
brake system:
Connecting a hydraulic trailer-brake
system directly to the vehicle brake
system is dangerous and will result in
inadequate braking and possible injury.
Always use lower gears to reduce
speed:
Holding the brake pedal down too
long or too frequently is dangerous as
it could cause the brakes to overheat
and lose power, resulting in loss of
control and a serious accident. Use
lower gears to help reduce speed. Pull
off the road and allow brakes to cool
down whenever braking performance
feels reduced.
CAUTION
Do not tow a trailer during the first
1,000 km (600 miles) of your new
Mazda. If you do, you may damage
the engine, transmission, differential,
wheel bearings, and other
power-train components.
 Be aware of the towing load weight
differences when towing at high
altitudes. For altitudes exceeding
1,000 meter (3,280 ft 10 in), always
reduce the towing load by 10 % for
every 1,000 meter (3,280 ft 10 in)
increase in altitude from the load
indicated under the maximum
GCWR heading in the trailer
towing-load table. If the determined
maximum total towing load weight is
exceeded, the engine and other
power-train parts may be damaged.
 The total trailer weight and tongue
load can be determined by weighing
the trailer on platform scales at a
highway weight station or a trucking
company.
Make all hitch adjustments with
actual loads. Do not load and
unload vehicle while adjusting hitch.
This action will change the vehicle
height.
 Do not use an axle-mounted hitch.
This may damage the axle and
related parts.
 If the vehicle exceeds 100 km/h (62
mph) with a trailer in tow, the
vehicle could be damaged.
 Do not connect a trailer lighting
system directly to the lighting system
of your Mazda. This may damage
your vehicle's electrical system and
lighting systems. Have a recreational
vehicle dealer or trailer rental agency
connect the system, and inspect the
brake lights and turn signals yourself
before each trip.

Trailer tire size, load rating, and inflation pressures should conform to tire
manufacturer specifications.
Do not exceed 100 km/h (62 mph) with a trailer in tow. If the local legal
maximum speed with a trailer in tow is less than 100 km/h (62 mph), do not
exceed the legal speed.
Safety chains
Safety chains must be used as a precautionary measure should the trailer become
unintentionally unhitched. They should cross under the trailer tongue and attach to
the hitch. Leave enough slack to allow full turns. Consult literature published by your
trailer or hitch manufacturer for more details.
Tra i l e r l i g h t s
Trailer lights must comply with all federal, state, and local regulations. Equip your
trailer as required before towing it day or night.
Trailer brakes
If the total trailer weight exceeds 450 kg (1,000 lb), trailer brakes are required. If
your trailer has brakes, make sure they comply with all federal, state, and local
regulations.
Driving
Your Mazda will handle differently with a trailer in tow, so practice turning ,
backing , and stopping in a traffic-free area.
Take time to get accustomed to the extra weight and length.Allow more room between your vehicle and the one in front because braking
distance increases with a trailer. For each 16 km/h (10 mph) of speed, allow at
least one vehicle and trailer length between your Mazda and the vehicle ahead.
Avoid jerky starts or sudden acceleration.Avoid sudden braking. It may cause loss of control and result in
jackknifing,
especially so on wet or slippery roads.
Shift the selector lever to the D position when towing a trailer in hilly terrain or
when heavily loaded.
The D position will allow operating the vehicle without frequent shifting.
Lane changes and turning
Avoid quick lane changes, sudden turns, and tight turns. Slow down before turning
to avoid the need of sudden braking.
A turning trailer will make a tighter arc than the tow vehicle. Compensate with turns
that are larger than normal.
Pa s s i n g
Plan well ahead to pass other vehicles, and provide plenty of room before changing
lanes. Crosswinds from passing vehicles, especially larger ones, and the effects of
rough roads will affect handling.
