STARTING THE ENGINE

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-start conditions. 

While Carrying the Advanced 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 WILL YOU NOTICE? On start-up, the engine speed 

and sound are elevated (1500 RPM) for less than one 
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 DOES THIS DO? This reduces emissions and allows Mazda to improve efficiency.

•   SHUT THE ENGINE OFF by making sure the vehicle is in Park (A/T) and 

setting the parking brake, 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 brake pedal.

EMERGENCY ENGINE STOP 

Pushing and holding the START/STOP ENGINE button or repeatedly pushing the START/
STOP ENGINE button while the engine is running will turn the engine OFF. Use only in case 
of an emergency.

NOTE: 

You can drive the vehicle during AWS activation; there is no need to wait.  

The engine may not start if the key cannot be detected. The key indicator light may flash 

RED or “Key not detected” may be displayed if the key is placed in the cup holder.

If the START/STOP ENGINE button indicator light flashes AMBER, this could indicate a 
problem with the engine starting system. You may not be able 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.
