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
Drive Selection
*Some models.
Drive Selection *
Drive selection is a system to switch the vehicle's drive mode. When the sport mode is
selected, vehicle's response against accelerator operation is enhanced. Use the sport mode
when higher vehicle response is required such as merging onto expressway or accelerating
to overtake.
CAUTION
Do not use the sport mode when driving on slippery roads such as wet or snow-covered
roads. It may cause tyre slipping.
NOTE
  When the sport mode is selected, driving at higher engine speeds increases and it may
increase fuel consumption. Mazda recommends to cancel the sport mode on normal
driving.
  Drive mode cannot be switched in the following conditions: 



 ABS/TCS/DSC is operating



 Steering wheel is being operated abruptly

When Driving
Power Steering
Power Steering
 












 Power steering is only operable when
the engine is running. If the engine is
off or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
  If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an expert repairer,
we recommend an Authorised Mazda
Repairer.
 


 The warning light noti¿ es the driver
of system abnormalities and operation
conditions.
  In addition, the buzzer may also activate
depending on the system abnormality or
operation condition.
  Refer to Warning Lights on page
4-38 .
  Refer to Power Steering Warning Buzzer
on page 7-53 .

CAUTION
Never hold the steering wheel to the
extreme left or right for more than
5 seconds with the engine running.
This could damage the power steering
system.

When Driving
i-ACTIVSENSE
NOTE
  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.
  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.
  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 travelling at a constant speed and
following a vehicle ahead.
  The Mazda Radar Cruise Control (MRCC) warning light (amber) illuminates when the
system has a malfunction.
 Refer to Warning Lights on page 4-38 .   The headway control operation can be cancelled and the system can be switched to
only cruise control. Refer to Cruise Control Function on page 4-145 .
Mazda Radar Cruise Control (MRCC) Display Indication
The setting status and operation conditions of the Mazda Radar Cruise Control (MRCC)
system are indicated in the active driving display.

How to Set the Distance Between Vehicles During Headway Control
The distance between vehicles is set to a shorter distance each time the
switch is pressed.
The distance between vehicles is set to a longer distance by pressing the
switch. The
distance-between-vehicles can be set to 4 levels; Long, medium, short, and extremely short
distance.

Distance-between-vehicles guideline
(at 80 km/h (50 mph) vehicle speed) Display
Long (about 50 m (164 ft))


Medium (about 40 m (131 ft))


Short (about 30 m (98 ft))


Extremely short (about 25 m (82 ft))



NOTE
  The distance between vehicles differs depending on the vehicle speed, and the slower
the vehicle speed, the shorter the distance.
  When the ignition is switched to ACC or OFF and then the engine is started again, the
system automatically sets the distance between vehicles to the previous setting.

NOTE
  The Mazda Radar Cruise Control
(MRCC) system may be cancelled
during rain, fog, snow or other
inclement weather conditions, or the
front surface of the radiator grille is
dirty.
  If you have temporarily cancelled
the Mazda Radar Cruise Control
(MRCC), you can return to your
previously set speed by pressing
the RES switch and after all of the
operation conditions have been met.

Shift-up/Shift-down Request Display (Manual Transaxle)
The shift-up or shift-down request display in the active driving display may be indicated
while the Mazda Radar Cruise Control (MRCC) is operating. When this occurs, shift gears
because the gear position is not appropriate.

Request Display
Shift up


Shift down



NOTE
  If the gears are not shifted up even though the shift-up request indication is displayed,
load will be applied to the engine and the Mazda Radar Cruise Control (MRCC)
system may be automatically cancelled or engine damage could occur.
  If the gears are not shifted down even though the shift-down request indication is
displayed, the Mazda Radar Cruise Control (MRCC) system may be automatically
cancelled or engine stalling could occur.

Cruise Control Function
While this function is operating, the
headway control operation is cancelled
and only the cruise control function
operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise control function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
Do not use the cruise control function
in the following locations:
Otherwise, it could lead to an accident.
 
 Roads with sharp curves and where
vehicle traf¿ c is heavy and there is
insuf¿ cient space between vehicles.
(Driving under these conditions
using the cruise control function is
not possible)
  Steep down slopes (Set speed may be
exceeded because suf¿ cient engine
braking cannot be applied)
  Slippery roads such as ice or snow-
bound roads (Tyres could spin
causing you to lose vehicle control)

Always drive carefully:
The warnings and brake control
will not operate after the headway
control function is cancelled and the
system is switched to only the cruise
control function. Depress the brake
pedal to decelerate according to the
surrounding conditions while keeping
a safer distance from the vehicle ahead
and always driving carefully.
Switching to cruise control function
When the MODE switch is pressed while
the Mazda Radar Cruise Control (MRCC)
system is turned on, the system switches to
the cruise control function.
When the system switches to the cruise
control function, the cruise main indication
(white) is displayed in the instrument
cluster and the active driving display to
notify the driver as follows:
 


 The Mazda Radar Cruise Control
(MRCC) set indication (green) or the
Mazda Radar Cruise Control (MRCC)
main indication (white) is turned off,
and the cruise main indication (white) is
turned on.

WARNING
Always turn off the cruise control
function when it is not in use:
Leaving the cruise control function
turned on when it is not in use
is dangerous as it could operate
unexpectedly, resulting in an accident.
How to set the speed
Adjust the system to the desired vehicle
speed using the accelerator pedal.
When the SET
or SET switch is
pressed, the cruise set indication (green) is
turned on and headway control begins.
