When Driving
Automatic Transaxle
Transaxle Ranges
 












 The shift position indicator light in the
instrument cluster illuminates. Refer
to Warning/Indicator Lights on page
4-38 .
 


 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
4-204 .
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.

*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.

*Some models.
Smart City Brake Support [Forward] (SCBS F) *
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
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 ¿ rmly and quickly to
assist. (Brake Assist (SCBS brake assist))

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 tyre 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.
  The 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.
 

 
 Do not apply stickers to the surface of the windscreen 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.
 

 
 Do not apply coating agent to the windscreen. Otherwise, the laser sensor may
not be able to detect vehicles or obstructions in front which could result in an
accident.
 

 
 Do not disassemble the laser sensor.


 
 If cracks or damage caused by À ying 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 expert repairer, we recommend an Authorised
Mazda Repairer. If the vehicle continues to be driven with cracks or scratch marks
left on the windscreen 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 4-160 .
 

 
 When replacing the windscreen wipers or windscreen, consult an expert repairer,
we recommend an Authorised Mazda Repairer.

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.
