Instrument Cluster and Display
Wrench Warning Indicator Light
When the ignition is switched ON, the
warning light is illuminated and then turns
off after a few seconds.
The wrench warning indicator light is
illuminated when the preset maintenance
period arrives. Verify the content and
perform maintenance.
Refer to Maintenance Monitor on page
6-20 .
Low Engine Coolant Temperature Indicator Light (Blue)
The light illuminates continuously when
the engine coolant temperature is low and
turns off after the engine is warm.
If the low engine coolant temperature
indicator light remains illuminated after
the engine has been suffi ciently warmed
up, the temperature sensor could have
a malfunction. Consult an Authorized
Mazda Dealer.

Switches and Controls
Auto-wiper control
When the wiper lever is in the
position, the rain sensor senses the amount
of rainfall on the windshield and turns the
wipers on or off automatically (off—
intermittent—low speed—high speed).
The sensitivity of the rain sensor can be
adjusted by turning the switch on the
wiper lever.
From the center position (normal), rotate
the switch downward for higher sensitivity
(faster response) or rotate it upward for
less sensitivity (slower response).

Switches and Controls
NOTE
 y Switching the auto-wiper lever from the
to the position while driving
activates the windshield wipers once,
after which they operate according to
the rainfall amount.
 y  The auto-wiper control may not operate
when the rain sensor temperature is
about -10 °C (14 °F) or lower, or about
85 °C (185 °F) or higher.
 y If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.
 y If dirt or foreign matter (such as ice or
matter containing salt water) adheres
to the windshield above the rain sensor,
or if the windshield is iced, it could
cause the wipers to move automatically.
However, if the wipers cannot remove
this ice, dirt or foreign matter, the auto-
wiper control will stop operation. In
this case, set the wiper lever to the low
speed position or high speed position
for manual operation, or remove the
ice, dirt or foreign matter by hand to
restore the auto-wiper operation.
 y If the auto-wiper lever is left in the
position, the wipers could
operate automatically from the effect of
strong light sources, electromagnetic
waves, or infrared light because the
rain sensor uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the
position other
than when driving the vehicle under
rainy conditions.
 y  The auto-wiper control functions can
be turned off. Refer to Personalization
Features on page 9-12 .
Windshield Washer
Pull the lever toward you and hold it to
spray washer fl uid.
Washer
OFF
NOTE
With the wiper lever in the or
intermittent position/
position, the
wipers will operate continuously until the
lever is released.
If the washer does not work, inspect the
fl uid level (page 6-31 ). If the fl uid level
is normal, consult an Authorized Mazda
Dealer.

Radar Sensor
Radar Sensor
Your vehicle is equipped with a radar sensor.
The following systems also use the radar sensor.
 y Mazda Radar Cruise Control (MRCC) y Forward Obstruction Warning (FOW)
The radar sensor functions by detecting the radio waves refl ected off a vehicle ahead or an
obstruction sent from the radar sensor.
The radar sensor is mounted behind the front emblem.
Radar Sensor
If the Forward Obstruction Warning (FOW) indicator light (amber) is illuminated, the area
around the radar sensor may be dirty. Refer to “Warning Guidance” in the type B audio
display.
Refer to If a Warning Light Turns On or Flashes on page 7-24 .

When Driving
Radar Sensor
NOTE
 y In the following cases, the radar sensor may not be able to detect vehic\
les ahead or
obstructions.
 y The rear surface of a vehicle ahead does not refl ect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
 y Vehicles ahead with low vehicle height and thus less area for refl ecting radio waves. y Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.
 y The trunk/luggage compartment is loaded with heavy objects or the rear passenger
seats are occupied.
 y Ice, snow, or soiling is on the front surface of the front emblem. y During inclement weather such as rain, snow, or sand storms. y When driving near facilities or objects emitting strong radio waves.
 y In the following cases, the radar sensor may detect vehicles in the oppo\
site lane or
surrounding obstructions, or it may not be able to detect vehicles ahead or \
obstructions.
 y The beginning and end of a curve. y Roads with continuous curves. y Narrow lane roads due to road construction or lane closures. y The vehicle ahead enters the radar sensor's blind spot. y The vehicle ahead is running abnormally due to accident or vehicle damag\
e.  y Roads with repeated up and down slopes y Driving on poor roads or unpaved roads. y The distance between your vehicle and the vehicle ahead is extremely short. y A vehicle suddenly comes close such as by cutting into the lane.
 y To prevent incorrect operation of the system, use tires of the same specifi ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with signifi cantly different wear patterns or tire pressures on the same vehicle. (Including
the temporary spare tire)
 y If the battery power is weak, the system may not operate correctly. y When driving on roads with little traffi c and few vehicles ahead or obstructions for the
radar sensor to detect, Forward Obstruction Warning/Smart City Brake Support (FOW/
SCBS) indicator light temporarily illuminates, however, this does not indicate a problem.

Brake
Smart City Brake Support (SCBS) *
The Smart City Brake Support (SCBS) system is designed to reduce damag\
e in the
event of a collision by operating the brake control (SCBS brake) when \
the system's laser
sensor detects a vehicle ahead and determines that a collision with the \
vehicle ahead is
unavoidable. It may also be possible to avoid a collision if the relativ\
e speed between your
vehicle and the vehicle ahead is less than about 15 km/h (9.3 mph).
In addition, when the driver depresses the brake pedal while the system \
is in the operation
range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied fi\
rmly and quickly to
assist. (Brake Assist (SCBS brake assist))
Laser sensor
WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safe
driving: The Smart City Brake Support (SCBS) system cannot compensate for unsafe and reckless
driving, excessive speed, tailgating (following another vehicle too closely), and driving on
slippery roads such as wet, snowy, and icy roads (reduced tire friction and road contact
because of water on the road surface). You can still have an accident.

Laser Sensor Handling
The Smart City Brake Support (SCBS) laser sensor is installed at the t\
op of the windshield
near the rearview mirror.
Always keep the surface of the windshield around the laser sensor clean \
to assure proper
operation of the Smart City Brake Support (SCBS) system.
WARNING
As there is the possibility of eye damage occurring from the laser, always heed the
following precautions:
