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 veh\
icle 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 accord\
ing to the vehicle
speed, a notification 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
notifies 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 traffic 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 th\
e 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 r everse (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\
pr esence 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 traveling at an extr emely slow speed.
 The system does not operate with the following objects:
 Vehicles approaching in the opposite direction. Stationary objects (stopped vehicles, obstructions)

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, and by presetting the vehicle speed between 30 km/h (19 mph) an\
d 145 km/h (90 mph),
the driver is freed from having to constantly use the accelerator or bra\
ke pedals.
*1 Headway Control: Control of the distance between your vehicle and the ve\
hicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for ex\
ample, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient 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 specifically, 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 sufficiently 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 safer distance from vehicles ahead or on-coming vehicles.
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 Roads with sharp cur ves and where vehicle traffic is heavy and there is insufficient
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).
 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).
 Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control). 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.

 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 Contr ol (MRCC) system is in use, it does not cancel even
if the selector lever (automatic transaxle)/shift lever (manual trans\
axle) 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. The Mazda Radar Cruise Contr ol (MRCC) warning light (amber) illuminates when the
system has a malfunction.
Refer to Warning Lights on page 4-24. The headway contr ol operation can be canceled and the system can be switched to only
cruise control. Refer to Cruise Control Function on page 4-115.
