Switches and Controls
CAUTION
 


¾ Do not shade the light sensor by adhering a sticker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 


¾ The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windshield when the wiper lever is in the
position and the
ignition is switched ON as fi ngers could be pinched or the wipers and wiper blades could be
damaged when the wipers activate automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is particularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
 


y The headlights, other exterior lights and dashboard illumination may not turn off
immediately even if the surrounding area becomes well-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traffi c jams inside tunnels, or in indoor parking lots.
  In this case, the lights turn off if the light switch is turned to the position.



y(Without auto headlight off function)
 When the headlight switch is in the position and the ignition is switched to ACC or
the ignition is switched off, the headlights, other exterior lights and dashboard
illumination will turn off.
 


y The dashboard illumination can be adjusted by rotating the knob in the instrument cluster.
Also, the day/night mode can be changed by rotating the knob until a beep sound is heard.
To adjust the brightness of the dashboard illumination:
  Refer to Dashboard Illumination on page 4-18 .



y The sensitivity of the AUTO lights may be changed by an Authorized Mazda Dealer.
 Refer to Personalization Features on page 9-10 .

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
CAUTION
 


¾ Do not shade the rain sensor by
adhering a sticker or a label on the
windshield. Otherwise the rain sensor
will not operate correctly.
 




¾ When the wiper lever is in the
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 


¾ If the windshield above the rain
sensor is touched or wiped with a
cloth.
 


¾ If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
  Keep hands and scrapers clear of the
windshield when the wiper lever is in the
position and the ignition is
switched ON as fi ngers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
  If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely
that the engine is left running) this is
particularly important when clearing ice
and snow.
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 9-10 .

i-ACTIVSENSE
Distance Recognition Support System (DRSS) *
The Distance Recognition Support System (DRSS) measures the distance between your
vehicle and a vehicle ahead using a radar sensor (front) while the vehicle speed is 30 km/h
or faster (19 mph or faster), and indicates a recommended distance to maintain between the
vehicles. Furthermore, if your vehicle approaches a vehicle ahead more closely than the
appropriate distance to maintain between the vehicles, the vehicle-ahead indication in the
active driving display is fl ashed to advise the driver to keep a safer distance from the vehicle
ahead.
WARNING
Do not rely completely on the Distance Recognition Support System (DRSS) and always
drive carefully:
The Distance Recognition Support System (DRSS) provides advice for safer driving and
notifi es the driver of a recommended, safer distance to maintain with a vehicle ahead.
The ability to detect a vehicle ahead is limited depending on the type of vehicle ahead,
the weather conditions, and the traffi c conditions. Therefore, if the accelerator and brake
pedals are not operated correctly it could lead to an accident. Always verify the safety of
the surrounding area and depress the brake pedal or accelerator pedal while keeping a
safer distance from vehicles ahead or on-coming vehicles.
NOTE
 


y The Distance Recognition Support System (DRSS) operates when all of the following
conditions are met:
 


y The ignition is switched ON.



y The Distance Recognition Support System (DRSS) is on.



y The selector lever is in a position other than reverse (R).



y The vehicle speed is 30 km/h or faster (19 mph or faster).




y The objects which activate the system are 4-wheeled vehicles.



y The Distance Recognition Support System (DRSS) may also operate in the presence of
motorcycles and bicycles.
 


y The Distance Recognition Support System (DRSS) may not operate normally under the
following conditions:
 


y The Dynamic Stability Control (DSC) has a malfunction.



y The vehicle ahead is traveling at an extremely slow speed.




y The system does not operate with the following objects:




y Vehicles approaching in the opposite direction.



y Stationary objects (stopped vehicles, obstructions)
