Active Sound Control feature in Lexus vehicles is designed to adjust the sound of the engine and other systems according to the driving conditions and your preferences. ASC can be activated in three different modes: Sport, Touring, and ECO.
The Sport mode amplifies the engine noise and gives it a more aggressive sound. The Touring mode makes the engine quieter and smoother, while the ECO mode makes the engine even quieter and also adjusts the climate control and seats to be more energy-efficient.

The ASC mode is designed to maximize the fuel efficiency of your Lexus vehicle. However, it is not the most effective way to improve your fuel economy. Driving habits and driving style are much more important factors that affect your fuel economy.

If you disable the ASC mode, your Lexus vehicle will have a slightly louder engine noise and some other systems will also sound different from usual. The ECO mode will be inactive as well as it is controlled by the same button as the ASC mode.
Is the Active Sound Control feature safe?
The Active Sound Control is completely safe and has no adverse effects on any Lexus vehicle. However, it is important to note that if you disable the ASC mode, some systems will sound different than usual, so this change could be distracting for drivers that are used to a certain noise level.
How long does it take to activate the ASC mode?
If you push the ECO button twice in one second, the Active Sound Control feature will be activated in Sport mode for two seconds. Then it activates in Touring mode in another two seconds and then in ECO mode after four seconds. This cycle repeats itself when you push the ECO button again.
How do I turn off the Active Sound Control feature?
If you push the ECO button once, the Active Sound Control feature will be switched off completely. If you hold the ECO button for five seconds or longer, it will deactivate all functions that are controlled by the ECO button. These include seat heaters or coolers, heated steering wheel, air purifier, and air conditioning.
