To disable the auto start-stop function on the Mazda CX-5, simply press the designated button. For permanent deactivation, you need to visit a 4S shop for settings. Below are situations where turning off the auto start-stop is recommended: 1. When driving on a very steep slope: It is highly advisable not to activate the auto start-stop. Although the auto start-stop duration is brief, the engine's start-stop on a slope may lead to insufficient brake assistance. 2. During extremely hot weather in the south with the air conditioning running at full capacity: It is best to turn off the auto start-stop function. Since the air conditioning requires significant power consumption, the vehicle's electrical system may not provide enough power to keep the air conditioning running when the engine is off, causing discomfort to passengers. 3. When driving through water: It is recommended to disable the start-stop system to avoid the engine shutting off while driving. A sudden reduction in exhaust pressure could allow water to flow back into the engine through the exhaust pipe, potentially preventing the engine from restarting. 4. During heavy traffic congestion: It is advisable to turn off the auto start-stop. Prolonged engine shutdowns can cause the combustion chamber temperature to drop, leading to the formation of carbon deposits from unburned hydrocarbons and paraffin on the cylinder walls. These deposits can increase fuel consumption and reduce engine power, counteracting the fuel-saving purpose of the auto start-stop feature.
