When Driving
Mazda Radar Cruise Control (MRCC)
 y In the following cases, the warnings may not activate even if your vehic\
le starts closing in
on the vehicle ahead.
 y You are driving at the same speed as the vehicle ahead. y Directly after the Mazda Radar Cruise Control (MRCC) system has been set. y When the accelerator pedal is depressed or directly after the accelerator pedal is
released.
 y Another vehicle cuts into the driving lane.
 y The following are not detected as physical objects.
 y Vehicles approaching in the opposite direction y Pedestrians y Stationary objects (stopped vehicles, obstructions)
 y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
 y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
 y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
 y During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to\
close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
 y While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel even
if the selector lever (automatic transaxle)/shift lever (manual trans\
axle) is operated and
any intended engine braking will not occur. If deceleration is required, lower the vehicle
speed setting or depress the brake pedal.
 y The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating, however, they may not be illuminated while the vehicle is
on a down slope at the set vehicle speed or traveling at a constant spee\
d and following a
vehicle ahead.
 y The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the system
has a malfunction.

When Driving
Tire Pressure Monitoring System
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all\
four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster \
and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent fr\
om the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-106 .
The warning light fl ashes when the system has a malfunction.

country other
than the U.S.A., Canada, or Mexico, the system has to be turned off usin\
g the Blind Spot
Monitoring (BSM) OFF switch.
Blind Spot Monitoring (BSM)
The Blind Spot Monitoring (BSM) system monitors the detection areas on\
both sides of
the vehicle to the rear and when there are vehicles in the detection are\
a it notifi es the driver
by illuminating the Blind Spot Monitoring (BSM) warning light while th\
e vehicle speed is
about 10 km/h (6.2 mph) or faster and driving forward.
If the turn signal lever is operated to the side the Blind Spot Monitori\
ng (BSM) warning
light is illuminated, the Blind Spot Monitoring (BSM) warning light fl\

Maintenance and Care

WARNING
Do not replace the xenon fusion bulbs
yourself: Replacing the xenon fusion bulbs
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Consult an Authorized
Mazda Dealer when the replacement is
necessary.

Never touch the glass portion of a
halogen bulb with your bare hands
and always wear eye protection when
handling or working around the bulbs: When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it will
explode and serious injuries could be
caused by the fl ying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.

Always keep halogen bulbs out of the
reach of children: Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
NOTE
 y To replace the bulb, contact an
Authorized Mazda Dealer.
 y If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
 y Use the protective cover and carton for
the replacement bulb to dispose of the
old bulb promptly and out of the reach
of children.
Replacing Exterior Light Bulbs
Headlights (With xenon fusion
headlights)
Low/High beam bulbs
You cannot replace the low/high beam
bulbs by yourself. The bulbs must be
replaced at an Authorized Mazda Dealer.

1. If you are changing the right bulb, start the engine, turn the steering wheel all
the way to the left, and turn off engine.
If you are changing the left bulb, turn
the steering wheel to the right, and turn
off engine.
2. Make sure the headlight switch is off.
