When the car reaches the speed that you would like to attain (say 55 MPH) and levels off (stays at 55 MPH) the engine does not require as much gas as when you are getting up to speed (0 - 54 MPH). So considering this, Overdrive is when you get up to speed and the amount of gas put into the chambers is reduced, (but you still continue at 55 MPH) saving tons of gas and is easier on your engine. The overdrive on/off switch controls the transmission. If overdrive is off (indicated by light on dash) vehicle will not shift into overdriven gear (4th gear); which can be useful for mountain driving. Overdrive should be on though as it will greatly effect your gas milage if it is off.
If the vehicle does not have an overdrive, then realistically, you can not.
does the 2010 hyundai santa fe have an on off overdrive switch where is it located
If the overdrive switch is turned off then the car will not go into overdrive. As it is not in overdrive, then it will not downshift out of overdrive as it normally would. It also will not shift to 3rd gear above a certain factory preset speed. Turn th overdrive on and see if it operates normally.
There is no overdrive, per se, but a mode switch called "Power Mode" that doubles as an overdrive, allowing more RPMs per gear.
There is no separate switch for the overdrive, simply put the gear selector in the overdrive position. It looks like a D inside a square. Not all Chevy Celebrities have the overdrive feature, it was an extra cost option.
The button does not switch from Overdrive to Automatic. The button just turns the overdrive off. Overdrive is not a separate drive system as your question implies. Normally you leave the car in overdrive mode. That way the transmission shifts into overdrive at highway speeds, thus saving fuel. If you are saying the transmission is stuck in overdrive and it will not disengage then seek out a A/T professional.
There is no "switch". To cancel overdrive move the gear lever from "D" to "4".
the fuse is in the dash behind the overdrive switch
Take it in. There is either a problem with your transmission or with the overdrive switch itself. Overdrive switch should be a lot cheaper to fix. I'm assuming the light not only goes on, but the overdrive physically turns off as well when the light is on.
The overdrive ON / OFF switch is located on the end of your gearshift lever ( P R N etc. )
bad fuse or bad switch
