β–Ό Fuel Requirements (SKYACTIV-G 2.0, SKYACTIV-G 2.5, SKYACTIV-G 2.5T)

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.

CAUTION

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.


- 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 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 other than 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.

β–Ό Fuel Requirements (SKYACTIV-D 2.2)

The vehicle will operate efficiently on diesel fuel with specification Ultra-Low Sulfur Diesel (ULSD, 15 ppm sulfur or less) fuel that meets the ASTM D975 standard or the equivalent.

CAUTION

Fuel grade labels are visible on fuel-filler lid, therefore, verify the fuel grade before refueling. If the fuel grade cannot be verified, ask the gas station attendant.


- Never use fuel other than specification Ultra-Low Sulfur Diesel (ULSD, 15 ppm sulfur or less) fuel that meets the ASTM D975 standard or the equivalent for your vehicle. Use of gasoline or kerosene in diesel engines will result in fuel system and engine damage.

- Never use diesel fuel with concentrations of methyl ester bio-diesel higher than 5 % (B5), such as B20 or B100.

- Never add fuel system additives other than a Mazda genuine product, otherwise the emission control system could be damaged. Consult an Authorized Mazda Dealer for details.

- If any type of incorrect fuel is accidently pumped into the fuel tank, do not turn on the engine and drive the vehicle. Consult an Authorized Mazda Dealer for assistance.

Turning on the engine or driving the vehicle with the incorrect fuel could cause damage to the fuel pump and fuel injectors.

- Do not mistake the refueling port for the DEF filler port. If fuel was added to the DEF filler port by mistake, do not turn on the engine and drive the vehicle. Consult an Authorized Mazda Dealer for assistance.

Turning on the engine or driving the vehicle with fuel in the DEF filler port could cause damage to the emission control system.


NOTE

- Fuel for winter driving is available. Ask the gas station attendant for details.

- When refueling, always add at least 10 L (2.6 US gal, 2.2 Imp gal) of fuel.

Low outside temperatures

When the outside temperature is low, diesel fuel (light oil) may freeze and clog the fuel pipe, leading to problems such as the engine not starting. When driving to a cold region, add winter grade diesel fuel as soon as possible.

WARNING

Never use engine starting assist additives:

Using engine starting assist additives is dangerous because they may cause a vehicle explosion or a vehicle runaway condition, leading to serious injury or death.

β–Ό Emission Control System (SKYACTIV-G 2.0, SKYACTIV-G 2.5, SKYACTIV-G 2.5T)

image

WARNING

This vehicle is equipped with an emission control system (the catalytic converter is part of this system) that enables the vehicle to comply with existing exhaust emissions requirements.



Never park over or near anything flammable:

Parking over or near anything flammable, such as dry grass, is dangerous. Even with the engine turned off, the exhaust system remains very hot after normal use and could ignite anything flammable. A resulting fire could cause serious injury or death.

CAUTION

Ignoring the following pre

CAUTION

s could cause lead to accumulate on the catalyst inside the converter or cause the converter to get very hot. Either condition will damage the converter and cause poor performance.

- USE ONLY UNLEADED FUEL.

- Do not drive your Mazda with any sign of engine malfunction.

- Do not coast with the ignition switched off.

- Do not descend steep grades in gear with the ignition switched off.

- Do not operate the engine at high idle for more than 2 minutes.

- Do not tamper with the emission control system. All inspections and adjustments must be made by a qualified technician.

- Do not push-start or pull-start this vehicle.


NOTE

- Under U.S. federal law, any modification to the original-equipment emission control system before the first sale and registration of a vehicle is subject to penalties. In some states, such modification made on a used vehicle is also subject to penalties.

- While the engine is off, the sound of a valve opening and closing can be heard at the rear of the vehicle, however this does not indicate an abnormality. The vehicle has a

self-checking device and it operates while the engine is off.


β–Ό Emission Control System (SKYACTIV-D 2.2)

This vehicle is equipped with an emission control system (the catalytic converter and the Selective Catalytic Reduction (SCR) system*1 are part of this system) that enables the vehicle to comply with existing exhaust emissions requirements.

*1 SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify the exhaust gas by injecting it with Diesel Exhaust Fluid (DEF). For more details, refer to the Selective Catalytic Reduction (SCR) System (page 4-228).

About the SCR system



image

WARNING

Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will not operate normally:

If the vehicle runs out of DEF, the vehicle speed is restricted in steps to prevent contaminants from being exhausted. When the remaining distance-to-empty reaches 0 km (0 miles) in the final stage, the engine is forced to idle. For replenishment of the DEF supply, consult an Authorized Mazda Dealer.


image

CAUTION

Use a Mazda genuine product or a product conforming to ISO22241-1 for DEF. If incompatible DEF is used, the SCR system may not operate normally. For the recommended DEF, consult the nearest Authorized Mazda Dealer.


NOTE

- When the remaining distance-to-empty is 640 km (400 miles) or shorter while the DEF WARNING indication is displayed, the SCR WARNING light turns on and the vehicle speed is restricted. In addition, if there is a problem with the SCR system/DEF and the remaining distance-to-empty is 200 km (125 miles) or shorter, the SCR WARNING light flashes and the vehicle speed is restricted.

- DEF needs to be replenished periodically according to the scheduled maintenance information. If a WARNING message is displayed in the multi-information display or the SCR WARNING light flashes, consult an Authorized Mazda Dealer.

- Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs to be replenished.

β–Ό Engine Exhaust (Carbon monoxide)



image

WARNING

Do not drive your vehicle if you smell exhaust gas inside the vehicle:

Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is colorless, odorless, and poisonous. When inhaled, it can cause loss of consciousness and death. If you smell exhaust gas inside the vehicle, keep all windows fully open and contact an Authorized Mazda Dealer immediately.


Do not run the engine when inside an enclosed area:

Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss of consciousness or even death could occur.

Open the windows or adjust the heating or cooling system to draw fresh air when idling the engine:

Exhaust gas is dangerous. When the vehicle is stopped with the windows closed and the engine running for a long time even in an open area, exhaust gas, which contains poisonous carbon monoxide, could enter the cabin. Loss of consciousness or even death could occur.

Clear snow from underneath and around your vehicle, particularly the tail pipe, before starting the engine:

Running the engine when a vehicle is stopped in deep snow is dangerous. The exhaust pipe could be blocked by the snow, allowing exhaust gas to enter the cabin. Because exhaust gas contains poisonous carbon monoxide, it could cause loss of consciousness or even death to occupants in the cabin.
