*Some models.
Lane Departure Warning System (LDWS)*
The LDWS system notifies the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffic lane using the Forward Sensing
Camera (FSC) and if it determines that the vehicle may be deviating from its lane, it notifies
the driver by flashing the LDWS warning light and activating the LDWS warning beep.
Use the LDWS when you drive the vehicle on roads with white or yellow li\
nes.
Refer to Forward Sensing Camera on page 4-84.

LD WS warning light
The warning light illuminates when the system has a malfunction.
Refer to Warning Lights on page 4-16.
WARNING
Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
 Driving on roads with tight curves. Driving under bad weather conditions (rain, fog, and snow).
The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the
LDWS it could lead to an accident. The driver is responsible for assuring lane changes and
other maneuvers. Always pay attention to the direction in which the vehicle is traveling
and the vehicle’s surroundings.

CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.
NOTE
 If your vehicle deviates from its traffic lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to \
the center of the lane. When the turn signal lever is operated for a lane change, the LDWS warni\
ng is
automatically canceled. The LDWS warning becomes operable when the turn \
signal lever
is returned and the system detects the white or yellow lines. If the steering wheel, accelerator pedal, or brake pedal is operated abr\
uptly and the
vehicle moves close to a white or yellow line, the system determines tha\
t the driver is
making a lane change and the LDWS warning is automatically canceled. The LDWS may not operate during the period immediately after the vehicle\
has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time. The LDWS does not operate if it does not detect the white or yellow lines of the traffic
lane.

Auto cancel warning
When the following operations are
performed, the LDWS determines that
the driver intends to make a lane change
and the LDWS warning is canceled
automatically. The LDWS is enabled
automatically after the driver performs the
operation.
 The steering wheel is operated abruptly. The brake pedal is depressed abruptly. The accelerator pedal is depressed
abruptly. The turn signal lever is operated (after
the turn signal lever is returned, the
LDWS may not operate for about 3
seconds which is the period of time
required to make a lane correction).
NOTE
After about 60 seconds have elapsed with
the turn signal lever left operating, the
LDWS warning may operate if the vehicle
is close to a white or yellow line.
Canceling the System
Press the LDWS switch to cancel the
LDWS. The LDWS OFF indicator light
turns on.
LDWS Warnng
If the system determines that there is the
possibility of a lane departure, the LDWS
warning beep activates and the LDWS
warning light flashes. Operate the steering
wheel appropriately and steer the vehicle
to the center of the lane.
NOTE
 If the LDWS warning sound is set to
rumble*1, the sound will be heard from
the vehicle speaker on the side which
the system determined the vehicle may
be deviating from its lane. It may be difficult to hear the LDWS
warning beep depending on the
surrounding conditions such as outside
noise. The volume of the LDWS warning sound
can be changed.
Refer to Personalization Features on
page 9-9. The type of warning sound (rumble*1/
beep) on the LDWS can be changed.
Refer to Personalization Features on
page 9-9.
*1 A rumble strip is a series of grooves
in the road pavement surface
positioned at specific intervals,
and when the vehicle passes over
it a vibration and rumble sound is
produced which alerts the driver
that the vehicle is departing from the
lane.
The rumble sound is a reproduction
of the sound which occurs when a
vehicle passes over a rumble strip.

NOTE
 The detection ability of the radar sensors (rear) has limitations. In the following cases,
the detection ability may lower and the system may not operate normally.
 The rear bumper near the radar sensors (rear) has become deformed. Snow, ice or mud adheres to the radar sensors (rear) on the rear bumper. Under bad weather conditions such as rain, snow and fog.
 Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be difficult to detect them.
 Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts. Vehicle shapes which do not reflect radar waves well such as empty trailers with a low
vehicle height and sports cars.
 Vehicles are shipped with the direction of the radar sensors (rear) adjusted for each
vehicle to a loaded vehicle condition so that the radar sensors (rear) detect approaching
vehicles correctly. If the direction of the radar sensors (rear) has deviated for some
reason, have the vehicle inspected at an Authorized Mazda Dealer. For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork,
and replacement near the radar sensors, consult an Authorized Mazda Dealer. Turn off the system while pulling a trailer or while an accessory such as\
a bicycle carrier
is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will\

be blocked causing the system to not operate normally. The radar sensors are regulated by the relevant radio wave laws of the country in which
the vehicle is driven. If the vehicle is driven abroad, authorization from the country in
which the vehicle is driven may be required.

Tire Pressure Monitoring System
*Some models.
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 from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specified
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-96.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on page 4-16.

When Driving
Tire Pressure Monitoring System
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle 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 pressure telltale when one or more of your tires
is significantly under-inflated. Accordingly, when the 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-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces 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 tire 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 will flash for approximately one minute and then
remain continuously illuminated. This sequence 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 that 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 for a little while before indicating a problem. As
a result it will not instantaneously register a rapid tire deflation or blow out.

Tire Pressure Monitoring System
Tire Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
 A tire pressure is adjusted. Tire rotation is performed. A tire or wheel is replaced. The battery is replaced or completely
drained. The tire pressure monitoring system
warning light is illuminated.
Initialization method
1. Park the car in a safe place and firmly
apply the parking brake.
2. Let the tires cool, then adjust the tire
pressure of all four (4) tires to the
specified pressure indicated on the tire
pressure label located on the driver's
door frame (door open).
Refer to Tires on page 9-8.
3. Switch the ignition ON.
4. While the vehicle is parked, press
and hold the tire pressure monitoring
system set switch and verify that
the tire pressure monitoring system
warning light in the instrument cluster
flashes twice and a beep sound is heard
once.
CAUTION
If the system initialization is performed
without adjusting the tire pressure,
the system cannot detect the normal
tire pressure and it may not illuminate
the tire pressure monitoring system
warning light even if a tire pressure is
low, or it may illuminate the light even
if the pressures are normal.
Adjust the tire pressure on all four
tires and initialize the system when
the warning light is turned on. If the
warning light turns on for a reason
other than a flat tire, the tire pressure
of all four tires may have decreased
naturally.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.
