SRS Air Bags
Do not increase the total seated weight on the front passenger seat:When an infant or small child sits on the front passenger seat, increasing the total seated
weight on the front passenger seat is dangerous. The front passenger seat weight sensors
will detect the increased total seated weight, which could result in the unexpected
deployment of the front passenger front and side air bags and seat belt pretensioner
system in an accident and may cause serious injury. Increasing the total seated weight on
the front passenger seat could result in the front passenger front and side air bags and
seat belt pretensioner system deployment in an accident under the following conditions,
for example:
 Luggage or other items are placed on the seat with the child in the child-restraint
system. A rear passenger or luggage push or pull down on the front passenger seatback. A rear passenger steps on the front passenger seat rails with their feet. Luggage or other items are placed on the seatback or hung on the head restraint. Heavy items are placed in the seatback map pocket. The seat is washed. Liquids are spilled on the seat. The front passenger seat is moved backward, pushing into luggage or other items
placed behind it. The front passenger seatback contacts the rear seat. Luggage or other items are placed between the front passenger seat and driver seat. Any accessories which might increase the total seated weight on the front passenger
seat are attached to the front passenger seat.
CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensors in
the front seat bottoms:
 Do not place sharp objects on the front seat bottoms or leave heavy luggage on them. Do not spill any liquids on the front seats or under the front seats.
 To allow the sensors to function properly, always perform the following:
 Adjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly. If you place your child on the front passenger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-30).

Constant Monitoring
The following components of the air bag systems are monitored by a diagn\
ostic system:
 Crash sensors, and diagnostic module (SAS unit) Front air bag sensors Air bag modules Side crash sensors Air bag/Front seat belt pretensioner system warning light Front seat belt pretensioners Related wiring
(With Front Passenger Occupant Classification System)
 Front passenger air bag deactivation indicator light Front passenger seat weight sensors Front passenger seat weight sensor control module Front passenger seat belt buckle switches
The diagnostic module continuously monitors the system's readiness. This begins when the
ignition is switched ON and continues while the vehicle is being driven.

Before Driving
Fuel and Emission
Fuel and Engine Exhaust Precautions
Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a min\
imum.

This vehicle will perform best with fuel listed in the table.

Fuel Octane Rating * (Anti-knock index)
Regular unleaded fuel 87 [(R
M)/2 method] or above (91 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline stat\
ion pumps.

Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission control
system performance and could also cause engine knocking and serious engi\
ne damage.
CAUTION
 ¾ USE ONLY UNLEADED FUEL. Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 ¾ This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the vehicle may occur when ethanol exceeds this recommendation, or
if the gasoline contains any methanol. Stop using gasohol of any kind if your vehicle engine
is performing poorly.
 ¾  Never add fuel system additives, otherwise the emission control system could be damaged.
Consult an Authorized Mazda Dealer for details.

Gasoline blended with oxygenates such as alcohol or ether compounds are \
generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10 %. Gasoline containing alc\
ohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resulting from the use of the fol\
lowing may not be
covered by the warranty.
 y  Gasohol containing more than 10 % ethanol. y Gasoline or gasohol containing methanol. y Leaded fuel or leaded gasohol.

WARNING
Always adjust the display brightness and position with the vehicle stopped:
Adjusting the display brightness and position while driving the vehicle is dangerous as
doing so could distract your attention from the road ahead and lead to an accident.
CAUTION
 Do not try to adjust the angle or open/close the active driving display manually.
Fingerprints on the display will make it difficult to view and using excessive force when
operating it could cause damage.
 Do not place objects in the vicinity of the active driving display. The active driving display
may not operate or any interference with its operation could cause damage. Do not place beverages near the active driving display. If water or other liquids are splashed
on the active driving display, it could cause damage. Do not place objects above the active driving display screen or apply stickers to the
combiner as they will cause interference. A sensor is int
egrated to control the display's luminosity. If the optical receiver is covered,
the display's luminosity will lower making the display difficult to view. Do not allow intense light to hit the optical receiver. Otherwise, it could cause damage.
NOTE
 It may be difficult to view the display when wearing sunglasses. Take off your sunglasses
or adjust the luminosity. If the battery has been removed and re-installed or the battery voltage is low, the adjusted
position may deviate. The display may be difficult to view or temporarily affected by weather conditions such as
rain, snow, light, and temperature. If the audio system is removed, the active driving display cannot be operated.
