Mazda 2: i-stop

The i-stop function automatically stops the engine when the vehicle is stopped at a traffi c light or stuck in traffi c, and then restarts the engine automatically to resume driving. The system provides improved fuel economy, reduced exhaust gas emissions, and eliminates idling noise while the engine is stopped.

Engine idle stopping and restarting

NOTE

The i-stop indicator light (green) turns on under the following conditions:

Engine idle stopping and restarting


Manual transaxle

  1. Stop the vehicle by depressing the brake pedal and then the clutch pedal.
  2. While depressing the clutch pedal, shift the shift lever to the neutral position. Engine idling stops after the clutch pedal is released.
  3. The engine restarts automatically when the clutch pedal is depressed.

Automatic transaxle

  1. Engine idling stops when the brake pedal is depressed while the vehicle is driven (except for driving in the R or M position second gear fi xed mode) and the vehicle is stopped.
  2. The engine restarts automatically when the brake pedal is released with the selector lever in the D or M position (not in second gear fi xed mode).
  3. If the selector lever is in the N or P position, the engine does not restart when the brake pedal is released. The engine restarts when the brake pedal is depressed again or the selector lever is shifted to the D, M (not in second gear fi xed mode) or the R position.

    (For the purposes of safety, always keep the brake pedal depressed when shifting the selector lever while engine idling is stopped.)

Under the following conditions, engine idling stops and the i-stop indicator light (green) turns on.

The engine is not cold.

The fuel injection amount learning, which is performed periodically and automatically, is not being performed.

The engine has been started and the vehicle is driven for a certain period.

The engine is started with the bonnet closed.

 The battery is in good condition

All doors, liftgate/boot lid, and bonnet are closed.

The driver's seat belt is fastened.

The air conditioner is not operating with the airfl ow mode dial in the position (A/C
ON).

(Automatic air-conditioning)

The i-stop warning light (amber) is not turned on/fl ashing.

The keyless entry & push button start system functions are normal.

The brake vacuum is suffi ciently high.

The steering wheel is not being operated.

(Manual transaxle)

(Automatic transaxle)

When the system is not operable

Engine idling does not stop in the following conditions:

The temperature setting dial for the air conditioning is set to the maximum cooling (A/C ON) position.

There is a large difference between the cabin temperature and the set temperature of the air-conditioner.

The vehicle is stopped on a steep incline.

The steering wheel is not in the straight-ahead position while the vehicle is stopped.

 (SKYACTIV-D 1.5)

The particulate matter (PM) is being removed by the diesel particulate fi lter (DPF).

NOTE

Under the following conditions, a period of time is required to stop engine idling

After PM removal is performed by the diesel particulate fi lter (DPF).

Engine does not restart

If the following operations are performed while the idling is stopped, the engine will not restart for safety reasons. In such cases, start the engine using the normal method.

(Manual transaxle)   With the shift lever in a position other than neutral, the driver's seat belt is unfastened and the driver's door is opened.

(Automatic transaxle)  With the selector lever in the D or M (not in second gear fi xed mode), the driver's seat belt is unfastened and the driver's door is opened.

Engine-stop period is short or time until next engine idle stop is long

Engine restarts automatically while engine idling is stopped

Under the following conditions, the engine restarts automatically.

The temperature setting dial of the air-conditioner is set to maximum cooling (A/C ON).

The cabin temperature is largely different from the set temperature of the airconditioner

The accelerator pedal is depressed with the selector lever in the D or M (not in second gear fi xed mode) position.

The selector lever is shifted to the R position.

The selector lever is shifted from N or P position to D or M (not in second gear fi xed mode) position.

The steering wheel is operated with the selector lever in the D or M (not in second gear fi xed mode) position.

The selector lever is in the M position and the second gear fi xed mode is selected.

(Except European model)

Selector lever is operated while engine idling is stopped (automatic transaxle)

If the selector lever is shifted from D or M (not in second gear fi xed mode) position to N or P position while engine idling is stopped, the engine does not restart even when the brake pedal is released. The engine will restart if the brake pedal is depressed again or the selector lever is shifted to the D, M (not in second gear fi xed mode), or R position. (For the purposes of safety, always keep the brake pedal depressed when shifting the selector lever while engine idling is stopped.)

If the selector lever is shifted from the D or M (not in second gear fi xed mode) position to the N or P position, and the driver's seat belt is unfastened and the driver's door is opened, the engine does not restart. Start the engine using the normal method.

(Except European model)

If the selector lever is shifted from the D or M (not in second gear fi xed mode) to the N or P position, and the driver's seat belt is unfastened and the driver's door is opened, the engine restarts.

Battery terminals are disconnected

Engine idling may not stop right after the battery terminals are disconnected. In addition, if the battery is replaced, the i-stop functions must be verifi ed. Consult an expert repairer, we recommend an Authorised Mazda Repairer.

i-stop Warning Light (Amber)/i-stop Indicator Light (Green)


To ensure safe and comfortable use of the vehicle, the i-stop system constantly monitors the driver's operations, the vehicle's interior and exterior environment, and the operational status of the vehicle, and uses the i-stop warning light (amber) and i-stop indicator light (green) to inform the driver of various cautions and warnings.

NOTE

On vehicles equipped with the centre display, the i-stop operation status is displayed in the fuel monitor control status display.

Refer to Control Status Display on page 4-90 .

i-stop warning light (amber)

When the light is turned on

The bonnet is opened.

(European model)  The driver's seat belt is unfastened and the driver's door is opened.

(Except European model)

NOTE

A problem in the system may be indicated under the following conditions. Have your vehicle inspected at an expert repairer, we recommend an Authorised Mazda Repairer.

i-stop OFF Switch

i-stop OFF Switch


By pressing the switch until a beep sounds, the i-stop function is turned off and the i-stop warning light (amber) in the instrument cluster turns on. By pressing the switch again until the beep sounds, the i-stop function becomes operational and the i-stop warning light (amber) turns off.

NOTE

If the engine is stopped with the i-stop function cancelled, the i-stop function becomes operational when the engine is started the next time.

Vehicle Roll Prevention Function (Automatic transaxle)

Vehicles with the i-stop function are equipped with a vehicle roll prevention function. This function prevents the vehicle from rolling, such as when releasing the brake pedal while on a slope under the following conditions:

Vehicle Roll Prevention Function (Automatic transaxle)


WARNING

Do not rely completely on the vehicle roll prevention function.

The vehicle roll prevention function is a supplementary function which operates for a maximum of four seconds after releasing the brake pedal and accelerating the vehicle from an engine idling stop condition. Over reliance on the system may result in an unexpected accident if the vehicle were to suddenly accelerate. Before starting to drive the vehicle, always confi rm the safety of the surroundings and operate the selector lever, brake pedal, and accelerator pedal appropriately. Note that the vehicle may move suddenly depending on the vehicle's load or if it is towing something.

Note that the vehicle may move suddenly after the vehicle roll prevention function is released while the vehicle is under the following conditions: The selector lever is in the N position.

If the selector lever is shifted to the N position and the brake pedal is released while the i-stop function is operating, the brake force is gradually released. To accelerate the vehicle, release the brake pedal after the engine restarts and shift the selector lever to a position other than the N position.
