When Driving
Automatic Transaxle
Transaxle Ranges
 












 The shift position indicator light in the
instrument cluster illuminates. Refer
to Warning/Indicator Lights on page
4-36 .
 


 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 3-52 ).
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
4-212 .
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.

*Some models.
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 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 according to the vehicle
speed, a noti¿ cation 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
noti¿ 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 traf¿ 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.



 The Distance Recognition Support System (DRSS) is on.



 The selector lever is in a position other than reverse (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 presence 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 travelling at an extremely slow speed. 

 The system does not operate with the following objects: 



 Vehicles approaching in the opposite direction.



 Stationary objects (stopped vehicles, obstructions)

*Some models.
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, which frees the driver 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 suf¿ cient distance between the vehicles.
The possible vehicle speed setting ranges are as follows:
 


 (European models) 
 About 30 km/h (19 mph) to 200 km/h (124 mph)



 (Except European models) 
 About 30 km/h (19 mph) to 145 km/h (90 mph)
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.

Smart City Brake Support [Reverse] (SCBS R) *
The Smart City Brake Support [Reverse] (SCBS R) is a system which is designed to reduce
damage in the event of a collision by operating the brake control (SCBS brake) when the
system’s ultrasonic sensors detect an obstruction at the rear of the vehicle while driving
at a speed of about 2 to 8 km/h (2 to 4 mph) and the system determines that a collision is
unavoidable.

WARNING
Do not rely completely on the Smart City Brake Support [Reverse] (SCBS R) system:  
 The Smart City Brake Support [Reverse] (SCBS R) 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.
  To assure the correct operation of the Smart City Brake Support [Reverse] (SCBS R),
heed the following cautions.
 

 
 Do not apply a sticker to an ultrasonic sensor (rear) (including transparent
stickers). Otherwise, the ultrasonic sensor (rear) may not be able to detect vehicles
or obstructions which could result in an accident.
 

 
 Do not disassemble an ultrasonic sensor (rear).


 
 If cracks or damage caused by À ying gravel or debris is visible around an ultrasonic
sensor (rear), stop using the Smart City Brake Support [Reverse] (SCBS R)
system
immediately and have your vehicle inspected by an expert repairer, we recommend
an Authorised Mazda Repairer. If the vehicle continues to be driven with cracks
or scratch marks left around an ultrasonic sensor, the system may operate
unnecessarily and cause an unexpected accident.
  Refer to Stopping the Smart City Brake Support [Reverse] (SCBS R) System
Operation on page 4-175 .



 
 Consult an expert repairer, we recommend an Authorised Mazda Repairer for rear
bumper replacement.

Do not modify the suspension:
If the vehicle height or inclination is changed, the Smart City Brake Support [Reverse]
(SCBS R) system may not operate correctly because it cannot detect obstructions
correctly.

Do not apply a strong force to an ultrasonic sensor (rear):
When washing the vehicle, do not spray highly pressurised water against an ultrasonic
sensor (rear), or rub it strongly. In addition, do not hit the rear bumper forcefully
when loading and unloading cargo Otherwise, the sensors may not detect obstructions
correctly which could cause the Smart City Brake Support [Reverse] (SCBS R) system
to not operate normally, or it could operate unnecessarily.
