No
most of the time it saves gas but you should use low gear when towing or going down a steep hill
yes it is, unless your in the mountains, going up a steep hill, or towing.
If you are not towing anything for sure disengage the overdrive on an A/T. On a manual 5 speed put it in 4th, or 3rd, or 2nd, or even 1st gear depending on how steep the hill is and how fast you want to go.
You should leave the overdrive on all the time. If it is off there will be a od off light that will come on the dash. The trans. will know when to shift into and out of od. Unless you are going down a steep long hill and need engine braking so you don't have to brake as much or pulling heavy loads.
low gear, first or second depending on the steepness
most daewoo lanos's will only cut out on an extremely steep hill and if you are goin up a steep hill u should use the power button that is located on the gearstick of an automatic if it is a manual im sorry but i can not help you.
It depends how steep the hill is if it isn't very steep then they should b fine but I wouldn't recommend it if the hill is very steep
The overdrive should be switched off when you want to avoid unneccessary shifting. If you are driving on a hilly road, the vehicle will shift out of overdrive going uphill to maintain speed while pulling the vehicles weight up the hill, and shift into overdrive going down the hill to save fuel when additional engine power is not needed. When towing with an automatic transmission, the vehicle may tend to repeatedly shift in and out of overdrive due to the added weight. In scenerios such as these, you should turn off the overdrive to avoid the unneccesary shifting which puts more wear and tear on the transmission.
One gear down from normal road gear, but remember the transmission is not meant to be a brake.
Not at all. Overdrive is for high rpm acceleration like quick on ramps and passing, or even going up a hill. In snow u want a lower rpm so u don't lose traction.
It's easier because your not going up the hill at such a steep incline.
Overdrive allowed is the NORMAL position ( if I'm on the highway and have to go down a long / steep hill , I like to cancel the overdrive with the switch on the end of the gear selector so the transmission stays in drive and gives some engine braking )
