A front passenger is seated as shown in
the following figure:A rear passenger pushes up on the front
passenger seat with their feet.
 Luggage or other items placed under the
front passenger seat or between the front
passenger seat and driver seat that push
up the front passenger seat bottom.
 Any accessories which might decrease
the total seated weight on the front
passenger seat are attached to the front
passenger seat.
The front passenger front and side air
bags and knee air bags, and the seat belt
pretensioner system will deactivate if the
front passenger air bag deactivation
indicator light illuminates.

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 th e 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 knee
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 knee 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

Fuel and Engine Exhaust Precautions
▼Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use O
NLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.

This vehicle will per form 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 ab ove)
U.S. federal law requires that
octane ratings be posted on gaso line station 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 ser ious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic co nverter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 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.
 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 compo unds 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 conta ining alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability pr oblems resulting from the use of the following may not be
covered by the warranty.
Gasohol containing more than 10 % ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.
