It sounds like something to with air conditioning.
The ECT button on 4 runners stands for Electronically Controlled Transmission. Pushing this button disengages the control and changes the way the transmission handels loads. Like speeding up the motor on hills sooner when you have a load. Normal operation is to let the ECT control things. So button should always be off and no light on the control panel should be on.
I would suspect the same with the snow button except it will engage so it wont send too much power to quickly to the wheels. Thus helping eliminate spin of the wheels on slick surfaces.
The Highlander is a sport utility vehicle made by Toyota since 2000. The ECT button near the gearstick is a electronically controlled transmission snow mode, which means when engaged this mode will start the vehicle slowly to avoid wheel spinning in bad weather especially snow.
Its near the gear....a button with ECT written on it...
You push the ECT PWR button (located left to the radio) to the "Off" position.
mine is a button on middle council, by emergency brake. says ect
Below the left Air Conditioner vent on a 2004 Tacoma.
makes you explode and you go in "turbo mode" aka ejector seat
press the button that says ECT PWR ON/OFF !! It's on the centre console (close to the gearstick)
holds first and second gear longer for more acceleration with button on, if you floor it then you've already defeated it's purpose.
ECT button allow you to switch between Power and Normal mode. Normal mode is more fuel efficient but not as responsive. In Power mode cars become more responsive but consume more fuel.
The SNOW button seen in many Toyota vehicles is used in situations where there might be an increased chance of wheel spin. It simply changes the way power is delivered, by offering a slower more relaxed take off. In some cases, the vehicle will even start off in 2nd gear to give the vehicle a better chance of gaining traction in snowy or slippery conditions.
According to the Toyota's owners manual, 'the etc. power button is used for powerful acceleration. Whereby the transmission is shifted up and down at a higher vehicle speed than when in the normal switch position. It is used when the overdrive switch is on.'
