Break-In Period
▼Break-In Period
No special break-in is necessary, but if
unnecessary hard stops are avoided in
the
first 1,000 km (600 miles), it may
add to the performance, economy,
and life of the vehicle.
Hazardous Driving
▼ Hazardous Driving
WARNING
Be careful when applying sudden
regenerative braking on slippery
surfaces:
The sudden change in tire speed could
cause the tires to skid. This could lead
to loss of vehicle control and an
accident.
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 4-63.
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 front wheels.
NOTE
Use snow chains only on the front
wheels.

Winter Driving
▼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 Coolant on page 6-11.
Inspect the lead-acid battery and its
cables. Cold reduces battery
capacity.
Inspect the EV system for damage
and loose connections.
Use washer fluid made with
antifreeze ―but do not use coolant
antifreeze for washer fluid (page
6-13).
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 a ffected 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.
▼ Snow Tires
Use snow tires on all 4 wheels
Do not go faster than 120 km/h (75
mph) while driving with snow tires.
In
flate snow tires 30 kPa (0.3 kgf/cm
2,
4.3 psi) more than recommended on
the tire pressure label (rear door on the
driver's side), but never more than the
maximum cold-tire pressure shown on
the tires.

The vehicle is originally equipped with
all season radials designed to be used
all year around. In some extreme
climates you may find it necessary to
replace them with snow tires during
the winter months to further improve
traction on snow and ice covered
roads.
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all 4
wheels:
Using tires di fferent in size or type is
dangerous. Your vehicle's handling
could be greatly aff ected and result in
an accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
The tire pressure monitoring system
may not function correctly when using
tires with steel wire reinforcement in
the sidewalls (page 4-181).
▼ Tire Chains
Check local regulations before using
tire chains.

There is the possibility of forgetting
that the selector lever is shifted to
the R position when only reversing
the vehicle a little. After reversing the
vehicle, immediately shift the
selector lever to the N or P position,
and before starting to drive the
vehicle again, check the shift
position indication in the instrument
cluster.
When driving
WARNING
Do not shift the selector lever to the N
position while driving:
Decelerat ion using the regenerat ive
braking is not possible which could
result in an accident.
Normal driving
Shift the selector lever to the D
position to drive the vehicle.
Acceleration/deceleration is
performed using the accelerator and
brake pedals.
Driving on steep upslopes
Slowly depress the accelerator pedal to
adjust the vehicle speed.
Driving on downslopes
On long or steep downslopes, increase
the amount deceleration using the
regenerative braking in regenerative
braking level change mode.
CAUTION
 On long downslopes, operate the
regenerative braking and the foot
brake together. Frequent
deceleration by depressing the brake
pedal could cause the disc brakes to
overheat and become ine ffective.
 If only strong regenerative braking is
used continuously, it could stop
working temporarily.
Regeneration braking is less e ffective
the closer the high voltage battery is
to a full charge, and regeneration
braking will not work when the high
voltage battery is fully charged.
Stopping the vehicles
1. After completely stopping the vehicle, continue to depress the
brake pedal firmly.
2. If necessary, apply the parking brake with the brake pedal
depressed.
3. If the vehicle is going to be parked for a long time, shift the selector
lever to the P position with the
brake pedal depressed.
WARNING
Do not depress the accelerator pedal
unnecessarily while the vehicle is
stopped:
If the accelerator pedal is mistakenly
depressed when the selector lever is in
a position other than the P or N
position, the vehicle could suddenly
accelerate resulting in an accident.
After stopping the vehicle, check the
shift position indication in the
instrument cluster before
re-accelerating:
If the vehicle were to move in the
unintended direction, it could lead to
an accident.
CAUTION
Do not depress the accelerator pedal
and the brake pedal at the same time,
or rev the motor with the selector lever
in the forward drive position while the
vehicle is stopped on an upslope. The
motor could overheat and lead to
damage.

Brake System
▼Foot Brake
This vehicle has power-assisted brakes
that adjust automatically through
normal use.

Should power-assist fail, you can stop
by applying greater force than normal
to the brake pedal. But the distance
required to stop will be greater than
usual.
WARNING
Do not coast with the EV system
stopped and stop the vehicle in a safe
place:
Coasting the vehicle with the EV
system stopped is dangerous. Braking
will require more
eff ort, and the
brake's power-assist could be
depleted if you pump the brake. This
will cause longer stopping distances or
even an accident.
Shift to a lower gear when going
down steep hills:
Driving with your foot continuously on
the brake pedal or steadily applying
the brakes for long distances is
dangerous. This causes overheated
brakes, resulting in longer stopping
distances or even total brake failure.
This could cause loss of vehicle control
and a serious accident. Avoid
continuous application of the brakes.
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
a ff ected.
CAUTION
 Do not drive with your foot held on
the brake pedal. Doing so could
result in the following:
 The brake parts will wear out more
quickly.
 The brakes can overheat and
adversely
aff ect brake
performance.
 Always depress the brake pedal with
the right foot. Applying the brakes
with the unaccustomed left foot
could slow your reaction time to an
emergency situation resulting in
insu fficient braking operation.
 Wear shoes appropriate for driving in
order to avoid your shoe contacting
the brake pedal when depressing the
accelerator pedal.
▼ Electric Parking Brake (EPB)
The EPB system applies the parking
brake using an electric motor. The

▼Brake Pad Wear Indicator
When the disc brake pads become
worn, the built-in wear indicators
contact the disc plates. This causes a
screeching noise to warn that the pads
should be replaced.
When you hear this noise, consult an
Authorized Mazda Dealer as soon as
possible.
WARNING
Do not drive with worn disc pads:
Driving with worn disc pads is
dangerous. The brakes could fail and
cause a serious accident. As soon as
you hear a screeching noise consult an
Authorized Mazda Dealer.
NOTE
In high humidity weather conditions,
brake noises, such as brake squeak or
brake squeal can be heard. It does not
indicate a malfunction.
▼Brake Assist
During emergency braking situations
when it is necessary to depress the
brake pedal with greater force, the
brake assist system provides braking
assistance, thus
enhancing braking
performance.

When the brake pedal is depressed
hard or depressed more quickly, the
brakes apply more firmly.
NOTE
When the brake pedal is depressed
hard or depressed more quickly, the
pedal will feel softer but the brakes
will apply more firmly. This is a
normal eff ect of the brake assist
operation and does not indicate a
malfunction.
When the brake pedal is depressed
hard or depressed more quickly, a
motor/pump operation noise may
be heard. This is a normal e ffect of
the brake assist and does not
indicate a malfunction.
The brake assist equipment does not
supersede the functionality of the
vehicle's main braking system.

Emergency Stop SignalSystem
▼Emergency Stop Signal System
If you apply the brakes suddenly while
driving at a speed of about 55 km/h
(34 mph) or faster, the emergency stop
signal system automatically and rapidly
fl
ashes all the turn signal lights to
caution drivers behind your vehicle of
the sudden braking situation.
NOTE
Flashing
When you bring your vehicle to a
complete stop while all the turn
signal lights are flashing rapidly, the
rapid flashing of all the turn signal
lights changes back to the normal
fl ashing pattern. The turn signal lights
turn o ff when you release your foot
from the brake pedal.
Operation
When the ABS operates, the

slippery road, all of the turn signal
lights may flash.
The emergency stop signal system
does not operate when the hazard
warning light switch is pressed.
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.
The HLA operates when the vehicle is
tilted rearward with the selector lever
in a forward gear, and operates when
the vehicle is tilted forward with the
selector lever in the R position.
WARNING
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.
The vehicle could roll depending on
the vehicle's load.
Always con firm 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.
