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.

▼Lane Departure Warning System
(LDWS)
The LDWS alerts the driver that the
vehicle may be deviating from its lane.
The system detects the white (yellow)
lines on the traffic lane using the
forward sensing camera (FSC) and if it
determines that the vehicle might be
deviating from its lane, it
notifies the
driver by the LDWS.
Refer to Forward Sensing Camera
(FSC) on page 4-197.
Use the LDWS when you drive the
vehicle on roads with white (yellow)
lines.
1. Forward sensing camera (FSC)
WARNING
Do not rely completely on the LDWS:

compensate for a driver’s lack of
caution and relying too much on the
system could lead to an accident.
 The functions of the LDWS have
limitations. Always stay on course
using the steering wheel and drive
with care.
CAUTION
Heed the following cautions so that
the LDWS can operate normally.
Do not modify the vehicle's
suspensions.
 Always use tires of the specified type
and size for the front and rear
wheels. Consult an Authorized
Mazda Dealer for tire replacement.
NOTE
The system may not operate normally
under the following conditions.
The white (yellow) lane lines are less
visible because of dirt or paint
flaking.
White (yellow) lane lines are less
visible because of bad weather (rain,
fog, or snow).
The vehicle is driven on a temporary
lane or section with a closed lane
resulting from construction where
there might be multiple white
(yellow) lane lines, or they are
interrupted.
The camera picks up an obscure line,
such as a temporary line being used
for construction, or because of
shade, unmelted snow, or groovesfilled with water.

▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle
lane if the vehicle might be deviating.
The forward sensing camera (FSC)
detects the white lines (yellow lines) of
the vehicle lane in
which the vehicle is
traveling and if the system determines
that the vehicle may deviate from its
lane, it operates the electric power
steering to assist the driver’s steering
operation. The system also alerts the
driver by displaying an alert on the
multi-information display and the
active driving display. Use the system
when you drive the vehicle on roads
with white (yellow) lines such as
expressways and highways.
