When Driving
Switches and Controls
CAUTION
 

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


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


 If the windscreen is struck with a
hand or other object from either
outside or inside the vehicle.
  Keep hands and scrapers clear of the
windscreen 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
windscreen, 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
  Switching the auto-wiper lever from
the
to the position while
driving activates the windscreen
wipers once, after which they operate
according to the rainfall amount.
  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.
NOTE
  If the windscreen is coated with
water repellent, the rain sensor may
not be able to sense the amount of
rainfall correctly and auto-wiper
control may not operate properly.
  If dirt or foreign matter (Such as
ice or matter containing salt water)
adheres to the windscreen above
the rain sensor or if the windscreen
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.
  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.
  The auto-wiper control functions can
be turned off.

i-ACTIVSENSE *
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer driving by reducing the load on the
driver and helping to avert collisions or reduce their severity. However, because each system
has its limitations, always drive carefully and do not rely solely on the systems.
Active Safety Technology
Active Safety Technology supports safer driving by helping the driver to recognise potential
hazards and avert accidents.

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


 The ignition is switched ON. 

 The Distance Recognition Support System (DRSS) is on.



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



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

Mazda Radar Cruise Control (MRCC) *
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control *1
according to the vehicle speed using a radar sensor to detect the distance to a vehicle ahead,
which frees the driver from having to constantly use the accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for example, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a suffi cient distance between the vehicles.
The possible vehicle speed setting ranges are as follows:
 


(European models)
 About 30 km/h (19 mph) to 200 km/h (124 mph)



(Except European models)
 About 30 km/h (19 mph) to 145 km/h (90 mph)
