ABS/TCS/DSC
DSC OFF Indicator Light

This indicator light stays on for a few
seconds when the ignition is switched ON.
It also illuminates when the DSC OFF
switch is pressed and TCS/DSC is
switched off.
Refer to DSC OFF Switch on page 4-89 .

If the light remains illuminated and
the TCS/DSC is not switched off, take
your vehicle to an expert repairer, we
recommend an Authorised Mazda
Repairer. The DSC may have a
malfunction.
DSC OFF Switch
Press the DSC OFF switch to turn off the
TCS/DSC. The DSC OFF indicator light
in the instrument cluster will illuminate.


Press the switch again to turn the TCS/
DSC back on. The DSC OFF indicator
light will turn off.
NOTE
  When DSC is on and you attempt to
free the vehicle when it is stuck, or
drive it out of freshly fallen snow, the
TCS (part of the DSC system) will
activate. Depressing the accelerator
will not increase engine power and
freeing the vehicle may be dif¿ cult.
When this happens, turn off the TCS/
DSC.
  If the TCS/DSC is off when the
engine is turned off, it automatically
activates when the ignition is
switched ON.
  Leaving the TCS/DSC on will
provide the best traction.
  If the DSC OFF switch is pressed
and held for 10 seconds or more,
the DSC OFF switch malfunction
detection function operates and the
DSC system activates automatically.
The DSC OFF indicator light
turns off while the DSC system is
operative.
  (Vehicles with Smart City Brake
Support (SCBS))
 If the Smart City Brake Support
(SCBS) operates with the TCS/DSC
turned off, the TCS/DSC becomes
operational automatically.

When Driving
i-ELOOP
*Some models.
i-ELOOP *
i-ELOOP is a regenerative braking system. When you depress the brake pedal or use
engine braking, the kinetic energy that occurs is converted to electrical energy by the power
generator and the converted electrical energy is stored in the rechargeable battery (capacitor
and battery). The stored electricity is used as power to charge the battery and the vehicle's
electrical devices.
 


 A variable voltage alternator is incorporated in the power generator which converts
the kinetic energy to electricity and can generate electricity ef¿ ciently according to the
vehicle conditions.
 


 A capacitor is used to store large amounts of electricity instantly which can be utilized
quickly.
 


 A DC-DC converter is incorporated which steps down the stored electricity to voltage
useable by the vehicle's electrical devices.

When Driving
i-ACTIVSENSE
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 traf¿ c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the centre of the
lane.
  When the direction indicator lever is operated for a lane change, the LDWS warning
is automatically cancelled. The LDWS warning becomes operable when the direction
indicator lever is returned and the system detects the white or yellow lines.
  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 cancelled.
  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 traf¿ c
lane.

When Driving
i-ACTIVSENSE
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 cancelled
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 direction indicator lever is operated
(after the direction indicator 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 direction indicator lever left
operating, the LDWS warning may
operate if the vehicle is close to a white
or yellow line.
Cancelling The System
Press the LDWS OFF switch to cancel the
LDWS. The LDWS OFF indicator light
turns on.

*Some models.
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 about
30 km/h (19 mph) or faster, and if your vehicle approaches a vehicle ahead more closely
than what is appropriate for maintaining distance between the vehicles according to the
vehicle speed, a noti¿ cation in the active driving display is indicated to advise you to keep a
safe 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
noti¿ 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 traf¿ 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).


 The objects which activate the system are 4-wheeled vehicles. 
 The Distance Recognition Support System (DRSS) may also operate in the presence of
motorcycles and bicycles.
  The Distance Recognition Support System (DRSS) system may not operate normally
under the following conditions:
 


 The Dynamic Stability Control (DSC) has a malfunction.



 The vehicle ahead is travelling at an extremely slow speed. 

 The system does not operate with the following objects: 



 Vehicles approaching in the opposite direction.



 Stationary objects (stopped vehicles, obstructions)

*Some models.
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 (front) 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 suf¿ 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)
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.
