and operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF Indicator
Light remains illuminated, have the vehicle inspected at an Authorized Mazda Dealer as
soon as possible.
Some problem with the system including the Blind Spot Monitoring (BSM) warning
indicator lights has occurred.

may be difficult to detect them.
The vehicle speed when reversing is about 10 km/h (6.3 mph) or faster.
The radar sensor (rear) detection area is obstructed by a nearby wall or parked vehicle.
(Reverse the vehicle to a position where the radar sensor detection area is no longer
obstructed.)

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.
While the MRCC with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed or depress the brake pedal.
The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
The brake lights turn on while the MRCC with Stop & Go function automatic braking is
operating, however, they may not turn on while the vehicle is on a downslope at the set
vehicle speed or traveling at a constant speed and following a vehicle ahead.

WARNING
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 flying 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.
CAUTION
When removing the lens or lamp unit using
a flathead screwdriver, make sure that the
flathead screwdriver does not contact the
interior terminal. If the flathead screwdriver
contacts the terminal, a short circuit may
occur.
NOTE
To replace the bulb, contact an
Authorized Mazda Dealer.
If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
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 LED headlights)
The LED bulb cannot be replaced as a
single unit because it is an integrated unit.
The LED bulb has to be replaced with the
unit. We recommend an Authorized
Mazda Dealer when the replacement is
necessary.
Headlights/Daytime running lights
(With halogen headlights)
High-beams bulbs/Daytime running

Replacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses in
the cabin are normal, inspect the fuse
block under the hood.
If a fuse is blown, it must be replaced.
Follow these steps:

1. Make sure the ignition is switched off,and other switches are off.
2. Remove the fuse block cover.
3. If any fuse but the MAIN fuse is
blown, replace it with a new one of the
same amperage rating .
Normal
Blown
WARNING
Do not replace the main fuse by
yourself. Have an Authorized Mazda
Dealer perform the replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse is a
high current fuse. Incorrect
replacement could cause an electrical
shock or a short circuit resulting in a
fire.
4. Reinstall the cover and make sure that it is securely installed.
