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
 


y 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 center of the lane.
 


y When the turn signal lever is operated for a lane change, the LDWS warning is
automatically canceled. The LDWS warning becomes operable when the turn signal lever
is returned and the system detects the white or yellow lines.
 


y 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 canceled.
 


y 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.
 


y The LDWS does not operate if it does not detect the white or yellow lines of the traffi c
lane.

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, the vehicle-ahead indication in the
active driving 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
 


y The Distance Recognition Support System (DRSS) operates when all of the following
conditions are met:
 


y The ignition is switched ON.



y The Distance Recognition Support System (DRSS) is on.



y The selector lever is in a position other than reverse (R).



y The vehicle speed is 30 km/h or faster (19 mph or faster).




y The objects which activate the system are 4-wheeled vehicles.



y The Distance Recognition Support System (DRSS) may also operate in the presence of
motorcycles and bicycles.
 


y The Distance Recognition Support System (DRSS) may not operate normally under the
following conditions:
 


y The Dynamic Stability Control (DSC) has a malfunction.



y The vehicle ahead is traveling at an extremely slow speed.




y The system does not operate with the following objects:




y Vehicles approaching in the opposite direction.



y Stationary objects (stopped vehicles, obstructions)

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.

WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully:
The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifi cally, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the system has detection limitations depending on the type of vehicle
ahead and its conditions, the weather conditions, and the road conditions. Additionally,
the system may be unable to decelerate suffi ciently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which could result in 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.

Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 


¾ Roads with sharp curves and where vehicle traffi c is heavy and there is insuffi cient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
 


¾ When entering and exiting interchanges, service areas, and parking areas of highways
(If you exit a highway while headway control is in use, the vehicle ahead will no longer
be tracked and your vehicle may accelerate to the set speed).
 


¾ Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control).
 


¾ Long descending slopes (to maintain distance between vehicles, the system
automatically and continuously applies the brakes which could result in the loss of
brake power).

For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.
CAUTION
If the vehicle is towed or you are towing something, switch the Mazda Radar Cruise
Control (MRCC) system off to prevent an incorrect operation.
