 


 The selector lever must be in P or N to
operate the starter.

P (Park)
P locks the transaxle and prevents the front
wheels from rotating.
WARNING
Always set the selector lever to P and set
the parking brake:
Only setting the selector lever to the
P position without using the parking
brake to hold the vehicle is dangerous.
If P fails to hold, the vehicle could move
and cause an accident.

CAUTION
 


 Shifting into P, N or R while the vehicle is
moving can damage your transaxle.
 


 Shifting into a driving gear or reverse
when the engine is running faster than
idle can damage the transaxle.

R (Reverse)
In position R, the vehicle moves only
backward. You must be at a complete
stop before shifting to or from R, except
under rare circumstances as explained in
Rocking the Vehicle (page 3-51 ).
NOTE
(With parking sensor system)
When the selector lever is shifted to the R
position with the ignition switched ON, the
parking sensor system is activated and a
beep sound is heard.
Refer to Parking Sensor System on page
4-163 .

N (Neutral)
In N, the wheels and transaxle are not
locked. The vehicle will roll freely even
on the slightest incline unless the parking
brake or brakes are on.
WARNING
If the engine is running faster than idle,
do not shift from N or P into a driving
gear:
It's dangerous to shift from N or P
into a driving gear when the engine
is running faster than idle. If this is
done, the vehicle could move suddenly,
causing an accident or serious injury.

Do not shift into N when driving the
vehicle:
Shifting into N while driving is
dangerous. Engine braking cannot
be applied when decelerating which
could lead to an accident or serious
injury.

CAUTION
Do not shift into N when driving the
vehicle. Doing so can cause transaxle
damage.

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 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 according to the vehicle speed,
the area between the vehicle-ahead indication and the vehicle indication in the multi-
information display fl ashes in white 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
notifi 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 traffi 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. 

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) 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.

*Some models.
Smart City Brake Support (SCBS) *
The Smart City Brake Support (SCBS) system is designed to reduce damage in the event
of a collision by operating the brake control (SCBS brake) when the system's laser sensor
(front) detects a vehicle ahead and determines that a collision with a vehicle ahead is
unavoidable. It may also be possible to avoid a collision if the relative speed between your
vehicle and a vehicle ahead is less than about 20 km/h (12 mph).
In addition, when the driver depresses the brake pedal while the system is in the operation
range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied fi rmly and quickly to
assist. (Brake Assist (SCBS brake assist))


Laser sensor (front)

WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safer
driving:
The Smart City Brake Support (SCBS) system cannot compensate for unsafe and reckless
driving, excessive speed, tailgating (following another vehicle too closely), and driving on
slippery roads such as wet, snowy, and icy roads (reduced tire friction and road contact
because of water on the road surface). You can still have an accident.

Do not rely completely on the Smart City Brake Support (SCBS) system:  


 The 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.
 


 The 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.

Smart City Brake Support (SCBS) system be turned off .




 Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
 


 The laser sensor (front) 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.
