i-ELOOP
i-ELOOP *
On conventional vehicles, the kinetic energy that is generated when the vehicle is
decelerated by applying the brakes or during engine braking ends up being discarded as
heat. By utilizing this discarded kinetic energy to generate electricity and use it to power the
vehicle's electrical devices and accessories such as the A/C and audio, fuel consumption can
be reduced. Mazda's system for generating electricity from this kinetic energy is called the
Regenerative Braking System (i-ELOOP).

When Driving
Mazda Radar Cruise Control (MRCC)
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,
and by presetting the vehicle speed between 30 km/h (19 mph) and 145 km/h (90 mph) the
driver is freed 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.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.
WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully:
The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifi cally, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the system has detection limitations depending on the type of vehicle
ahead and its conditions, the weather conditions, and the road conditions. Additionally,
the system may be unable to decelerate suffi ciently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which could result in an accident. Always verify the safety of the surrounding area
and depress the brake pedal or accelerator pedal while keeping a safe distance from
vehicles ahead or on-coming vehicles.

When Driving
Mazda Radar Cruise Control (MRCC)
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
¾ Roads with sharp curves and where vehicle traffi c is heavy and there is insuffi cient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
¾ When entering and exiting interchanges, service areas, and parking areas of highways
(If you exit a highway while headway control is in use, the vehicle ahead will no longer
be tracked and your vehicle may accelerate to the set speed).
¾ Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control).
¾ Long descending slopes (to maintain distance between vehicles, the system
automatically and continuously applies the brakes which could result in the loss of
brake power).
For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.
CAUTION
If the vehicle is towed or you are towing something, switch the Mazda Radar Cruise
Control (MRCC) system off to prevent an incorrect operation.
NOTE
y The Mazda Radar Cruise Control (MRCC) system operates when all of the following
conditions are met.
y The vehicle speed is about 30 km/h (19 mph) to 145 km/h (90 mph).
y The Mazda Radar Cruise Control (MRCC) system is turned on.
y The parking brake is not applied.
y The Forward Obstruction Warning (FOW) indicator light (amber) does not illuminate.
y The Dynamic Stability Control (DSC) is operating normally.

y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
y 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.
y 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.
y 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 traveling at a constant speed and following a
vehicle ahead.
y The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the
system has a malfunction.

When Driving
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster while the vehicle
is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor
determines that your vehicle may hit a vehicle or obstruction ahead.
WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully:
Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. The ability to detect an obstruction is limited depending on the obstruction,
weather conditions, or traffi c conditions. Therefore, if the accelerator pedal or brake
pedal is mistakenly operated it could result in an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safe
distance from vehicles ahead or on-coming vehicles.
NOTE
y The Forward Obstruction Warning (FOW) system operates when all of the following
conditions are met:
y The ignition is switched ON.
y The Forward Obstruction Warning (FOW) system is on.
y The vehicle speed is about 15 km/h (10 mph) or faster.
y The relative speed between your vehicle and the vehicle or obstruction ahead is about
15 km/h (10 mph) — 145 km/h (90 mph).
y The Forward Obstruction Warning (FOW) system may not operate under the following
conditions:
y If there is the possibility of hitting only a part of a vehicle or obstruction ahead.
y If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.
y The DSC is malfunctioning.
y The vehicle is driven at the same speed as the vehicle ahead.
y The accelerator pedal is depressed.
y The brake pedal is depressed.
y The steering wheel is being operated.
y The selector lever is being operated.
