When Driving
Mazda Radar Cruise Control (MRCC)
 


y In the following cases, the warnings may not activate even if your vehicle 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 transaxle) 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 speed and following a
vehicle ahead.
 


y The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the
system has a malfunction.

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 from 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 4-107 .
The warning light fl ashes when the system has a malfunction.

When Driving
Tire Pressure Monitoring System
CAUTION
 


¾ Each tire, including the spare (if provided), should be checked monthly when cold and
infl ated to the infl ation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire infl ation pressure label. (If your vehicle has tires of a diff erent size than the
size indicated on the vehicle placard or tire infl ation pressure label, you should determine
the proper tire infl ation 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 signifi cantly under-infl ated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and infl ate them to the proper
pressure. Driving on a signifi cantly under-infl ated tire causes the tire to overheat and can
lead to tire failure. Under-infl ation also reduces fuel effi ciency and tire tread life, and may
aff ect 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-infl ation 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 fl ash 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.
 


¾ 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 defl ation or blow out.

Tire Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
 


y A tire pressure is adjusted.



y Tire rotation is performed.



y A tire or wheel is replaced.



y The battery is replaced or completely
drained.
 


y The tire pressure monitoring system
warning light is illuminated.
Initialization method
1. Park the car in a safe place and fi rmly
apply the parking brake.
2. Let the tires cool, then adjust the tire
pressure of all four (4) tires to the
specifi ed pressure indicated on the tire
pressure label located on the door jamb
of the driver's door (door open).
Refer to Tires on page 9-10 .
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
fl ashes 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.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.

When Driving
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster while the vehicle
is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor
determines that your vehicle may hit a vehicle or obstruction ahead.
WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully:
Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. The ability to detect an obstruction is limited depending on the obstruction,
weather conditions, or traffi c conditions. Therefore, if the accelerator pedal or brake
pedal is mistakenly operated it could result in an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safe
distance from vehicles ahead or on-coming vehicles.
NOTE
 


y The Forward Obstruction Warning (FOW) system operates when all of the following
conditions are met:
 


y The ignition is switched ON.



y The Forward Obstruction Warning (FOW) system is on.



y The vehicle speed is about 15 km/h (10 mph) or faster.



y The relative speed between your vehicle and the vehicle or obstruction ahead is about
15 km/h (10 mph) — 145 km/h (90 mph).
 


y The Forward Obstruction Warning (FOW) system may not operate under the following
conditions:
 


y If there is the possibility of hitting only a part of a vehicle or obstruction ahead.



y If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.



y The DSC is malfunctioning.



y The vehicle is driven at the same speed as the vehicle ahead.



y The accelerator pedal is depressed.



y The brake pedal is depressed.



y The steering wheel is being operated.



y The selector lever is being operated.



y The turn signal is being used.

When Driving
Forward Obstruction Warning (FOW)
 


y Although the objects which activate the system are 4-wheeled vehicles, the radar sensor
could detect the following objects, determine them to be an obstruction, and operate the
Forward Obstruction Warning (FOW) system.
 


y Objects on the road at the entrance to a curve (including guardrails and snow banks).



y A vehicle appears in the opposite lane while cornering or rounding a curve.



y When crossing a narrow bridge.



y When passing under a low gate or through a tunnel or narrow gate.



y When entering an underground parking area.



y Metal objects, bumps, or protruding objects on the road.



y If you suddenly come close to a vehicle ahead.



y When driving in areas where there is high grass or forage.



y Two-wheeled vehicles such as motorbikes or bicycles.



y Pedestrians or non-metallic objects such as standing trees.




y When the system operates, the user is notifi ed by the fl ashing warning light and the active
driving display.
 


y The indicator light turns on when the system has a malfunction.

When Driving
Lane Departure Warning System (LDWS)
Lane Departure Warning System (LDWS) *
The LDWS notifi es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffi c lane using the Forward Sensing
Camera (FSC). If it determines that the vehicle may be deviating from its lane, it notifi es
the driver by fl ashing the LDWS indicator light (green) and operating the LDWS warning
sound.
Refer to Forward Sensing Camera on page 4-63 .
Use the LDWS when you drive the vehicle on roads with white or yellow lines.

LDWS indicator light (Green)
The warning light fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-22 .
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.
 


¾ Driving on roads with tight curves.



¾ 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 cautions 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.

When Driving
Lane Departure Warning System (LDWS)
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
 


y If your vehicle deviates from its traffi c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
 


y When the turn signal lever is operated for a lane change, the LDWS warning is
automatically canceled. The LDWS warning becomes operable when the turn signal lever
is returned and the system detects the white or yellow lines.
 


y If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically canceled.
 


y 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.
 


y The LDWS does not operate if it does not detect the white or yellow lines of the traffi c
lane.
