NOTE
The jam-safe equipment does not
activate during easy closure operation
when the power liftgate is between the
near-shut position and fully closed
position.
When the power liftgate is moving in
the open/close direction and an
obstruction is detected, the beep
sound will be heard and the liftgate
moves in the reverse direction and
stops.

closes the liftgate completely from the
near-shut position.
This system also operates when the
liftgate is closed manually.
WARNING
When closing a liftgate, always keep
hands and fingers away from the
liftgate:
Placing hands or fingers around a
liftgate is dangerous because the
liftgate closes automatically from the
near-shut position, which could cause
hands and fingers to be pinched and
injured.

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
minimum.

To achieve maximum engine performance, use the
specified fuel.
Fuel
Octane Rating*1 (Anti-knock index)
Regular unleaded fuel 87 [(R+M)/2 method] or above (91 RON or above)
*1 U.S. federal law requires that octane ratings be posted on gas 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 serious
engine damage.
CAUTION
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.
 This vehicle can only use oxygenated fuel s 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 other th an a Mazda genuine product, 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 alcohol,
such as ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems 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.
