Do not hang any backpacks, bags or
pouches that cover the sides of the
seats that block the side air bags.
 Do not place any objects on the
assist grips. Only hang clothes
directly on the coat hooks.
Do not touch the components of the
supplemental restraint system after
the air bags have inflated:
Touching the components of the
supplemental restraint system after the
air bags have inflated is dangerous.
Immediately after inflation, they are
very hot. You could get burned.
Never install any front-end equipment
to your vehicle:
Installation of front-end equipment,
such as frontal protection bar
(kangaroo bar, bull bar, push bar, or
other similar devices), snowplow, or
winches, is dangerous. The air bag
crash sensor system could be affected.
This could cause air bags to inflate
unexpectedly, or it could prevent the
air bags from inflating during an
accident. Front occupants could be
seriously injured.
Do not modify the suspension:
Modifying the vehicle suspension is
dangerous. If the vehicle's height or
the suspension is modified, the vehicle
will be unable to accurately detect a
collision or roll-over accident resulting
in incorrect or unexpected air bag
deployment and the possibility of
serious injuries.To prevent false detection by the air
bag sensor system, heed the
following:
 Do not use tires or wheels other than
those specified for your Mazda:
Use of any tire or wheel other than
those
specified for your Mazda (page
9-8) is dangerous. Use of such
wheels will prevent the vehicle's
accident detections system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries.
 Do not overload your vehicle:
Overloading your vehicle is
dangerous as it could prevent the air
bag crash sensor system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries. The gross axle
weight rating (GAWR) and the gross
vehicle weight rating (GVWR) for
your vehicle are on the Motor
Vehicle Safety Standard Label on the
driver's door frame. Do not exceed
these ratings.

detects a person or an object in the
liftgate's path, the liftgate will move in
the reverse direction automatically and
stops.
WARNING
Always check the area around the
power liftgate before opening/closing
it:
Not checking for occupants and
objects around the power liftgate
before opening/closing it is
dangerous. The jam-safe equipment is
designed to prevent jamming in the
event an obstruction is in the liftgate's
path. The system may not detect
certain objects obstructing the liftgate
depending on the way they are
positioned and their shape. However,
if the jam-safe function detects an
obstruction and moves the liftgate in
the reverse direction, an occupant in
the liftgate's path could be seriously
injured.

High Beam ControlSystem (HBC)
*
▼ High Beam Control System (HBC)
The HBC determines the conditions in
front of the vehicle using the Forward
Sensing Camera (FSC) while driving in
darkness to automatically switch the
headlights between high and low
beams.
Refer to Forward Sensing Camera
(FSC) on page 4-197.
While driving the vehicle at a speed of
about 30 km/h (19 mph) or more, the
headlights are switched to high beams
when there are no vehicles ahead or
approaching in the opposite direction.
The system switches the headlights to
low beams when one of the following
occurs:
The system detects a vehicle or the
headlights/lights of a vehicle
approaching in the opposite
direction.
The vehicle is driven on roads lined
with streetlamps or on roads in
well-lit cities and towns.
The vehicle is driven at less than
about 20 km/h (12 mph).
The headlight high-beam indicator
light turns on while the high beams
are on.
1. Forward Sensing Camera (FSC)*1
*1 The recognition distance of the Forward
Sensing Camera (FSC) varies according to
the surrounding conditions.
The warning light turns on when the
system has a malfunction.
Refer to High Beam Control System
(HBC) Warning Indication/Warning
Light (Amber) on page 7-30.
CAUTION
Do not adjust the vehicle height,
modify the headlight units, or
remove the camera, otherwise the
system will not operate normally.
 Do not rely excessively on the HBC
and drive the vehicle while paying
sufficient attention to safety. Switch
the headlights between the high
beams and low beams manually if
necessary.
NOTE
The timing in which the system
switches the headlights changes under
the following conditions. If the system
does not switch the headlights
appropriately, manually switch
between high and low beams
according to the visibility as well as
road and traffic conditions.
When there are sources of light in
the area such as streetlamps,
illuminated signboards, and traffic
signals.
