CAUTION
 When driving off-road in areas where there is grass or forage, it is recommended that the
Smart City Brake Support (SCBS) system be turned off. Always use tires for all wheels that are of the specified size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with significantly different 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.
NOTE
 The Smart City Brake Support (SCBS) system will not operate if the dri\
ver is deliberately
performing driving operations (accelerator pedal and steering wheel). The Smart City Brake Support (SCBS) system will operate under the foll\
owing conditions.
 The engine is running. The Smart City Brake Support (SCBS) warning light (amber) does not i\
lluminate. The vehicle speed is between about 4 to 30 km/h (2 to 18 mph). The Smart City Brake Support (SCBS) system is not turned off. The DSC operation is not turned off using the DSC OFF switch. The DSC is not malfunctioning.
 The Smart City Brake Support (SCBS) detects a vehicle ahead by emittin\
g a near-infrared
laser beam and receiving the beam reflected off the reflector of the vehicle ahead, and
then using it for the measurement. Consequently, the Smart City Brake Support (SCBS)
may not operate under the following conditions:
 Reflection of the laser is poor due to the shape of the vehicle ahead. The vehicle ahead is significantly dirty. Under bad weather condition, such as rain, fog and snow . The window washer is being used or the windshield wipers ar e not used when it's
raining. The windshield is dirty. The steering wheel is turned completely left or right, or the vehicle is\
accelerated
rapidly and comes close to the vehicle ahead. Trucks with low loading platforms and vehicles with an extremely low or high profile. Vehicles with certain shapes such as a vehicle carrier.

Climate Control System
Operating Tips
 Operate the climate control system with
the engine running. To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running.
 Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
 Use the climate control system to defog
the windows and dehumidify the air. The recirculate mode should be used
when driving through tunnels or while in
a traffic jam, or when you would like to
shut off outside air for quick cooling of
the interior.
 Use the outside air position for
ventilation or windshield defrosting. If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
(With A/C switch)
 Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
 Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refilling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
For details, consult an Authorized
Mazda Dealer.
