Distance Recognition
Support System (DRSS)
í
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 multi-
information display is flashed 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 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
lThe Distance Recognition Support System
(DRSS) operates when all of the following
conditions are met:
lThe ignition is switched ON.lThe Distance Recognition Support
System (DRSS) is on.
lThe selector lever is in a position other
than reverse (R).
lThe vehicle speed is 30 km/h or faster
(19 mph or faster).
lThe objects which activate the system are 4-
wheeled vehicles.
lThe Distance Recognition Support System
(DRSS) may also operate in the presence of
motorcycles and bicycles.
lThe Distance Recognition Support System
(DRSS) may not operate normally under the
following conditions:
lThe Dynamic Stability Control (DSC)
has a malfunction.
lThe vehicle ahead is traveling at an
extremely slow speed.
lThe system does not operate with the
following objects:
lVehicles approaching in the opposite
direction.
lStationary objects (stopped vehicles,
obstructions)

Do not rely completely on the Smart City Brake Support (SCBS) system:
ØThe Smart City Brake Support (SCBS) system is only designed to reduce damage in
the event of a collision. Over reliance on the system leading to the accelerator
pedal or brake pedal being mistakenly operated could result in an accident.
ØThe Smart City Brake Support (SCBS) is a system which operates in response to a
vehicle ahead. The system may not be able to detect or react to two-wheeled
vehicles or pedestrians.
ØThe laser sensor for the Smart City Brake Support (SCBS) system is installed near
the rearview mirror. To assure the correct operation of the Smart City Brake
Support (SCBS), heed the following cautions.
ØDo not apply stickers to the surface of the windshield near the laser sensor
(including transparent stickers). Otherwise, the laser sensor may not be able to
detect vehicles ahead which could result in an accident.
ØDo not apply coating agent to the windshield. Otherwise, the laser sensor may
not be able to detect vehicles in front which could result in an accident.
ØDo not disassemble the laser sensor.
ØIf cracks or damage caused by flying gravel or debris is visible near the laser
sensor, stop using the Smart City Brake Support (SCBS) system immediately
and have your vehicle inspected by an Authorized Mazda Dealer. If the vehicle
continues to be driven with cracks or scratch marks left on the windshield near
the laser sensor, the system may operate unnecessarily and cause an
unexpected accident.
Refer to Stopping the Smart City Brake Support (SCBS) System Operation on
page 4-130.
ØWhen replacing the windshield wipers or windshield, consult an Authorized
Mazda Dealer.
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly
detect vehicles ahead. This will result in the Smart City Brake Support (SCBS) system
not operating normally or mistakenly operating, which could cause a serious
accident.
Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation
when the vehicle is running on a chassis roller or being towed. See the next page on
how to turn off the Smart City Brake Support (SCBS).

CAUTION
ØWhen driving off-road in areas where there is grass or forage, it is recommended
that the Smart City Brake Support (SCBS) system be turned off.
ØAlways use tires for all wheels that are of the specified size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tires with
significantly different wear patterns on the same vehicle as the Smart City Brake
Support (SCBS) system may not operate normally.
ØThe laser sensor includes a function for detecting a soiled windshield and
informing the driver, however, depending on the conditions, it may not detect
plastic shopping bags, ice or snow on the windshield. In such cases, the system
cannot accurately determine a vehicle ahead and may not be able to operate
normally. Always drive carefully and pay attention to the road ahead.
