NOTE
The setting can be changed so that the projected vehicle path lines are not displayed.
Refer to the Settings section in the Mazda Connect Owner's Manual.
How to use the projected vehicle path line function
CAUTION
 The front of the vehicle swings out wide wh en turning the steering wheel while reversing.
Maintain sufficient distance between the vehicle and an obstruction.
 The parking sensor detection range has limitat ions. For example, obstructions closing in
from the side and objects short in height ma y not be detected. Always confirm the safety
around the vehicle visually when driving.
For details, refer to the parking sensor obstru ction detection indication and warning sound.
Refer to Parking Sensor System on page 4-280.
NOTE
Because there might be a difference between the image displayed on the screen, such as
indicated in the following, and the actual conditions when parking, always check the
safety at the rear of the vehicle and the surrounding area directly with your eyes.
Even though the back end of the parking space (or garage) displayed on the screen and
distance guide lines appear parallel, they may not actually be parallel.
When parking in a space with a division line on only one side of the parking space, even
though the division line and the vehicle wi dth guide line appear parallel, they may not
actually be parallel.
The following shows an example of vehicle parking with the steering wheel turned to the
left while backing up the vehicle. When backing into a parking space from the opposite
direction, the steering operation is reversed.

NOTE
The parking sensor obstruction detection indication does not display. Switch the screen
display to the top view/rear view display if the parking sensor warning sound is activated.
The rear wide view screen displays the image at the rear of the vehicle at a wide angle
and corrects the image to help detect approaching obstructions from the side. Therefore, it
differs from the actual view.
▼ Margin of Error Between Road Surface
on Screen and Actual Road Surface
There might be some margin of error between the road surface appearing on the screen and
the actual road surface. A margin of error in the perceived distance could lead to an
accident, therefore be aware of the following conditions which can more easily produce
errors in the perceived distance.

The vehicle tilts due to weight of passengers and cargo.
If the vehicle is tilted, obstructi ons picked up by a camera can appear farther or closer than
the actual distance from the vehicle.

Tire Pressure Monitoring System
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more tires, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-26.
Refer to Taking Action on page 7-33.
Refer to Tire Inflation Pressure Warning Beep on page 7-46.

The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illumina te more frequently. Visually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the
inflation pressure recommended by the vehi
cle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pre ssure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when th e low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-in flated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduce s fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct ti re pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale wi ll flash for approximately one minute and then
remain continuously illuminated. This sequen ce will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle th at prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
 To avoid false readings, the system samples fo r a little while before indicating a problem. As
a result it will not instantaneously regi ster a rapid tire deflation or blow out.
▼System Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in the
following cases:
When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
When a metallic device such as a
non-genuine navigation system is
equipped near the center of the
dashboard, which may block radio
signals from the tire pressure sensor to
the receiver unit.
When using the following devices in the
vehicle that may cause radio
interference with the receiver unit.
A digital device such as a personal
computer.
A current converter device such as a
DC-AC converter.
When excess snow or ice adheres to the
vehicle, especially around the wheels.
When the tire pressure sensor batteries
are exhausted.
When using a wheel with no tire
pressure sensor installed.
When using tires with steel wire
reinforcement in
the sidewalls.
When using tire chains.

Selective Catalytic Reduction (SCR) System*
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it with Diesel Exhaust Fluid (DEF).
WARNING
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will
not operate normally.
When the remaining DEF is low, a message is displayed on the multi-information display, and
the SCR warning light turns on/flashes.
Refer to Selective Catalytic Reduction (SCR) System Indications on page 4-261.
In this case, consult an Authorized Mazda Dealer. If DEF needs to be replenished, add DEF
following the specified procedure.
Refer to Diesel Exhaust Fluid (DEF) Replenishment on page 6-30.
NOTE
DEF needs to be replenished periodically according to the scheduled maintenance
information.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished. However, it may need to be replenished earlier depending on the
driving and environmental conditions (such as putting a high load on the engine while
driving or driving the vehicle at high altitudes).
The sound of the SCR system operating may be heard from the area under the vehicle,
however, this does not indicate a problem.
▼ Selective Catalytic Reduction
(SCR) System Indications
As the remaining amount of Diesel Exhaust Fluid (DEF) lowers, the SCR system notifies
the driver using the following indications.
The vehicle speed may be restricted for a while even if the warning light turns off after
replenishing the DEF. To cancel the vehicle speed restriction immediately, switch the
ignition OFF after the warning light turns off and then switch the ignition ON again.
