STARTING THE ENGINE WITH  
ACCELERATED WARM-UP SYSTEM (AWS)

The Mazda3 is equipped with SKYACTIV combustion technology. This 

technology includes AWS (Accelerated Warm-up System) for optimal 

emission performance during cold starting conditions. 

While Carrying the Key…

•  Start the engine

 by pushing the START/STOP ENGINE button while  

pushing the clutch pedal (M/T) or the brake pedal (A/T).

 What you will notice?

 On start-up, the engine speed and sound are 

higher (1500 RPM) for less than 1 minute to quickly bring the catalyst 

to efficient operating temperature. The RPM will reduce to idle once the 

temperature is achieved. This is normal engine operation under cold 

start conditions.

     What this does?

 This heats up the catalytic converter faster to reduce 

emissions and allows Mazda to use an exhaust header on the engine (to 
improve efficiency and horsepower).

   NOTE:

 You can drive the vehicle during AWS activation, no need to wait.

Key

•  Shut the engine OFF

 by setting the parking brake/placing the 

vehicle in Park (A/T), then push the START/STOP ENGINE button.

•  Activate Accessories (ACC)

 by pushing the START/STOP 

ENGINE button once without pushing the clutch or brake pedal. 

•  Turn the ignition to the ON position

 by pushing the START/STOP 

ENGINE button twice without pushing the clutch or brake pedal.  

The key indicator light 

 in the instrument cluster will show 

GREEN

(engine ready to start) when the key is detected and the clutch pedal (M/T)  

or the brake pedal (A/T) is pushed. If the KEY warning light illuminates  

RED

, or the START/STOP ENGINE button indicator light flashes 

AMBER

, 

this could indicate a problem with the engine starting system and the 

inability to start the engine or switch the ignition to ACC or ON. Have your 

vehicle inspected at an Authorized Mazda Dealer as soon as possible.

   NOTE:

RED

Key Indicator Light may flash if the key is placed in the cup holder. 

The key may not be detected in the cup holder.
