Power Steering
 












 Power steering is only operable when
the engine is running. If the engine is
off or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
  If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an expert repairer,
we recommend an Authorised Mazda
Repairer.
 


 The warning light notifi es the driver
of system abnormalities and operation
conditions.
  In addition, the buzzer may also activate
depending on the system abnormality or

WARNING
Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
 
 Driving on roads with tight curves. 
 Driving under bad weather conditions (rain, fog, and snow).
The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the
LDWS it could lead to an accident. The driver is responsible for assuring lane changes
and other manoeuvres. Always pay attention to the direction in which the vehicle is
travelling and the vehicle’s surroundings.
CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.
NOTE
  If your vehicle deviates from its traffi c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the centre of the
lane.
  When the direction indicator lever is operated for a lane change, the LDWS warning
is automatically cancelled. The LDWS warning becomes operable when the direction
indicator lever is returned and the system detects the white or yellow lines.
  If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically cancelled.
  The LDWS may not operate during the period immediately after the vehicle has
deviated from its lane and the LDWS has operated, or the vehicle deviates from its
lane repeatedly within a short period of time.
  The LDWS does not operate if it does not detect the white or yellow lines of the traffi c
lane.

NOTE
  It might be impossible or diffi cult for the radar sensors (rear) to detect the following:




 Small, two-wheeled vehicles, bicycles, pedestrians, and stationary objects on or at
the edge of the road.
 


 Vehicles with body shapes off of which radar may not refl ect such as unloaded
trailers with a low vehicle height and sports cars.
 


 A vehicle is in the detection area in an adjacent lane to the rear but it is not
approaching. The system makes determinations based on the radar detection data
from approaching vehicles.
 


 Another vehicle is travelling at the same speed alongside the vehicle for extended
periods.
 


 Vehicles approaching from the opposite direction.



 Another vehicle which your vehicle is attempting to pass is in an adjacent lane.



 A vehicle is in an adjacent lane which is extremely wide. The radar sensors (rear)
detection area is set according to the lane width of general freeways.
 
 In the following cases, the RVM warning indicator light and the warning chime may
not activate or they may be delayed:
 


 Another vehicle moves from a lane two lanes over to the adjacent lane.



 When driving on a steep incline.



 When going over a mountain pass.



 When the turning radius is small (cornering around sharp curves, roundabouts, or
intersections).
 


 There is a difference in height between vehicle lanes.



 Immediately after this system is turned on. 

 If the lane width is extremely narrow, a vehicle in an adjacent lane two lanes over may
be detected. The radar sensors (rear) detection area is set according to the lane width of

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 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 display is
fl ashed 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.



 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:
