Mazda intelligent DriveSelect (Mi-Drive)
Mi-Drive is a system that switches the
drive modes depending on the driving
conditions, road conditions and
vehicle conditions. The Mi-Drive has
the following driving modes.
TOWING Mode
*
The vehicle is driven with both engine
and motor power to optimize its
power performance. This mode
reduces the loss of driving
performance due to increased weight
when towing a trailer and improves the
vehicle stability.
SPORT Mode
The vehicle is driven with both engine
and motor power to optimize its
maneuverability performance. This
mode increases vehicle response when
the accelerator pedal is depressed and
accelerates powerfully.
NORMAL Mode
The vehicle is driven so that the engine
and motor are efficiently controlled to
optimize fuel efficiency. If necessary,
the motor can be used as a generator
to charge the high voltage battery. In
addition, when the accelerator pedal is
depressed, the vehicle accelerates
using both engine and motor power.
When the vehicle is driven in NORMAL
mode only by motor power, the EV
drive indicator light
in the
instrument cluster turns on.
EV Mode
The vehicle is driven by motor power
using the electrical power stored in the
high voltage battery.
OFF-ROAD Mode
The vehicle is driven with both engine
and motor power to optimize its
power performance. This mode
prevents the drive wheels from
spinning during off-road driving and
improves the running performance.

NOTE
TOWING mode can be selected only
when electrically connected to the
trailer using a Mazda genuine trailer
hitch. In addition, it may take some
time until the connection is detected
and TOWING mode is displayed.
Consult an Authorized Mazda Dealer
for details.
Depending on driving conditions
when selecting TOWING mode/
SPORT mode/OFF-ROAD mode, the
vehicle may perform shift-down or
accelerate slightly.
When SPORT mode/OFF-ROAD
mode is selected, driving the vehicle
at higher engine speeds increases
and fuel economy may worsen.
Canceling SPORT mode/OFF-ROAD
mode during normal driving is
recommended.
When setting the Mazda Radar
Cruise Control (MRCC) while driving
in SPORT mode, the mode is
switched to NORMAL mode. In
addition, while the MRCC is being
used, the mode cannot be switched
to SPORT mode.
Switching to EV mode may not be
possible depending on the driving
operations, driving conditions, and
high voltage battery condition.
When the system determines that
the engine needs to be started while
the vehicle is being driven in EV
mode, the mode is switched to
NORMAL mode.
The remaining distance-to-full
discharge for EV mode may
decrease, even when the vehicle is
being driven in a mode other than
EV mode.
The maximum speed in EV mode is
140 km/h (86 mph).
The drive mode cannot be switched
in the following cases.
The Antilock Brake System (ABS) is
operating.
The Traction Control System (TCS)
is operating.
The Dynamic Stability Control
(DSC) is operating.
The steering wheel is being
operated abruptly.
The driving mode in which the
display in the instrument cluster is
grayed out cannot be selected.
When the vehicle power is switched
OFF, the mode returns to NORMAL
mode. However, TOWING mode
before switching the vehicle power
OFF is maintained only when the

Tire Pressure MonitoringSystem (TPMS)
The TPMS monitors the air pressure of
each tire and informs the driver of a
decrease in the tire air pressure when it
becomes lower than the specified air
pressure.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensor
Warning and Cautions forUsing the Tire Pressure Monitoring System
(TPMS)
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light
is
turned on or flashing.
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brake and reduce
the vehicle speed.
Do not ignore the TPMS warning light
when it is turned on or flashing.
Continuing to driv e the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.

How to Use the Tire
Pressure Monitoring System (TPMS)
Check the tire pressure
The current tire pressure can be
checked on the center display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
Low tire pressure warning
When a tire pressure of the specified
air pressure or lower is detected, the
TPMS warning light
turns on and a
warning indication is displayed in the
instrument cluster.
1. Message is displayed.
Action
1. Adjust the tire pressure to the appropriate pressure.
Refer to the Tires on page 10-71.
CAUTION
If the tire pressure is adjusted when
the tire is warm, the tire pressure
may lower below the specified
pressure after cooling and the
warning light may turn on. Adjust
the air pressure of the tires when
they are cold.
2. Make sure that the TPMS warning
light
is turned off.
3. If the TPMS warning light does
not turn off, drive the vehicle for 3
minutes or longer at a speed of 25
km/h (16 mph) or faster.
4. Make sure that the TPMS warning
light
is turned off.
If the TPMS warning light remains on
even after adjusting the tire pressure,
there is a possibility that the tire is flat.
CAUTION
When inspecting/adjusting the tire
pressures, do not apply excessive force
to the air valve of the tire pressure
sensor. Otherwise, the tire pressure
sensor could be damaged.
When changing tires and wheels
When changing the tires or wheels
(such as installing winter tires), it will
be necessary to register the ID signal
code of the tire pressure sensor to the
TPMS.
Have an Authorized Mazda Dealer do
the registration or register the ID signal
codes of the tire pressure sensors using
the following procedure.
NOTE
The tire pressure sensors on each
wheel have a unique ID signal code.
For the TPMS to operate correctly, the
ID signal codes of the tire pressure
sensors need to be registered to the
system.
1. Wait more than 19 minutes after changing a tire or wheel.
2. After more than 19 minutes have passed, drive the vehicle at a speed
of 25 km/h (16 mph) or faster for 3
minutes or longer. While driving,
the ID signal codes of the tire
pressure sensors are automatically
registered.

Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED
FUEL, which will reduce exhaust emissions and keep spark plug fouling to a
minimum.

To achieve maximum engine performance, use the specified fuel.
Fuel
Octane Rating*1 (Anti-knock index)
Premium unleaded fuel 91 [(R+M)/2 method] or above (96 RON or above)
Regular unleaded fuel with an octane rati ng from 87 to 90 (91 to 95 RON) can be
used, but this will reduce performance slightly, such as reduced engine output, and
engine knocking.
Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission
control system performance and could al so cause engine knocking and serious
engine damage.
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
CAUTION
 USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead
to deterioration of the emission control system and or failures.
 This vehicle can only use oxygenated fuels containing no more than 10 % ethanol
by volume. Damage to the vehicle may occur when ethanol exceeds this
recommendation, or if the gasoline cont ains any methanol. Stop using gasohol of
any kind if your vehicle engine is performing poorly.
 Never add fuel system additives other than a Mazda genuine product, otherwise
the emission control system could be damaged. Consult an Authorized Mazda
Dealer for details.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The comm on gasoline blend that can be used with
your vehicle is ethanol blended at no more than 10 %. Gasoline containing alcohol,
such as ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resulting from the use of the following may
not be covered by the warranty.
