Title: Do you use the "Over Drive" often?
Post by: theteng on October 02, 2008, 05:45:02 PM
Hi, Just got my ride yesterday and was reading thru the manual on the Over Dirve - "OD". The SE advised me to turn off the OD to save on fuel, however the Latio is programmed to reset to ON everytime i start the engine. Do you off the OD everytime you drive? or should just leave it as ON.

thanks.

Correct me if I am wrong guys .. overdrive force the car to be on 3rd gear. Technically, that will increase RPM when driving above 80 kmh leading to higher FC.

You should leave the "OD' as default. 

Normally i turn OD off when travelling in NSH for speeding up and overtaking.  A faster way to get power but also burn more fuel.

You sure about default OD on everytime you start your ride, mine is off everytime I start it but I have never tried to leave it on when I park my ride in the night so I don't know if it will stay on if I leave it on when I kill the engine at night.

(Think I got Mixed up,the light is off everytime I start the engine which means the OD is on.)

Funny, cannot be default off and it not programmed to, it just a button.  :smile:

Your SE was wrong, turn off OD drink more fuel as OD off means lower gear with more power. You should always turn on OD unless you r at mountainous area.

I think this "On" or "Off" thingy is confusing as the OD works the reverse if you On/Off it.  To put it simply, in normal daily driving, the word OD light should be off.

Correct me if I am wrong.
When you press the OD button and there will be light on the panel comes on with "OD OFF"....this means that your OD is ON and the system is "reminding" you consistently to turn it off.

Driving with OD on will consume more fuel...the same logic applies when u drive a manual car....when you want to overtake, u down shift ur gear and step on the accelerator to give u the sudden boast of power to lurch forward...but this consume more fuel...the same logic as dragging gear....so with OD ON...it means u r constantly dragging ur gear....

Was scolded by my driving instructor for dragging every gear when i was a student....tat is why when u see those zheng car....they sound like zooooooommmm........zoooooooommmmm......zoooommmmm......:yehyeh: :yehyeh: :yehyeh:

To simpify things,
1. When you engage OD button, OD light appear on your panel with label "OD OFF"
2. This is to remind you to turn it OFF
3. Press OD button again, OD light will disappear on your panel
4. This tell you that you car is back to nromal driving mode.

Hope this help.  :yehyeh:

"Generally speaking, overdrive (OD) is the highest gear in the transmission. For normal driving conditions, operation of the overdrive should be enabled only if the average speed is above 70 km/h. It may be necessary to switch it off if the vehicle is being operated in a mountainous area."

So if your panel shows "OD OFF" light up, that mean the OD is OFF or ON?

Hi sparkbt

Dun seem logical leh. If what you say is true then OD is by default turned off .. that means the fouth gear on 4AT is not availiable by default.

I think you Point 2 should read "2. This is to remind you to turn it ON"

Your OD is OFF not on, meaning you are on 3rd gear.  ;)

I just read the owner manual,

"Each time the engine is started, the transmission is automatically reset to OD "ON"."

"Push the OD switch to turn the OD "ON". The OD off indicator light will turn off.

In short, when OD is ON, the OD off indicator light should be off; when OD is OFF, the OD off indicator light should light up.

As shared in my previous post further up, the ON/OFF thingy is confusing to some extent.  To put this in simple term, during normal driving, make sure that the light is off.  Won't go wrong one.
Title: Re: Do you use the "Over Drive" often?
Post by: SoL on October 04, 2008, 02:13:03 AM
OD is like the fourth gear. When you start the engine, the light is off, meaning OD is on. Lets you save fuel mah.

Then if you want to press the button, the OD OFF button lights up, meaning now OD is OFF, and you can get up to third gear only. So to save fuel, don't touch the button at all. If you want more speed, can always step harder on the accelerator mah!  :smile:

Some changes :
1. When you engage OD button, OD light appear on your panel with label "OD OFF"
   - This is to tell you that the gear ratio is lock to highest Gear 3 (Gear 1 =>2=>3).
2. Press OD button again, OD light will disappear on your panel
   - This tell you that you car is back to normal driving mode (Gear 1 =>2=>3=>4)

Something extra ( http://en.wikipedia.org/wiki/Overdrive_(mechanics) ):
Overdrive can refer to two different things. An overdrive is a device which was commonly used in automobiles to allow the choice of an extra-high overall gear ratio for high speed cruising, thus saving fuel, at the cost of less torque.

It also refers to a combination of gearing inside a transmission or transaxle which results in the output speed being greater than the input speed. In the latter case, "overdrive" does not refer to a physically separate identifiable part/assembly.

In short, when OD is ON, the OD off indicator light should be off; when OD is OFF, the OD off indicator light should light up.

OK,it means that when you start the car, there is no orange colour light in the meter cluster once your engine is started, which is the normal way to drive the car, with the OD on which will give you the final drive which is the 4th gear, and even in 4th gear,you'll notice that there is a drop in rpm once you're crusing, believe is due to the torque converter in the AT box. You'll only need to hit the OD button to drop gear to overtake or to accelerate, and when you hit that button, the OD off light comes on in the meter cluster.

Haha.  That's why I say the ON/OFF thingy is confusing.  As long as the OD light indicator is off, it is in normal driving mode.

OD is not the highest gear. It represent 3rd gear.  ;)


The above information is misleading.  :nonod:

OD, otherwise known as overdrive represents the highest gear.

If a car like Geely CK, which is using 3 speed auto gearbox, then the 3rd gear is overdrive.

For Latio which is using 4 speed auto gearbox, so the overdrive is 4th gear.

For the latest model Honda Jazz which is using 5 speed auto gearbox, overdrive is 5th gear.

Hope this gives a correct and clearer picture to everyone. :smile:

Arias....think u got confused...the "OD OFF" indicator is to tell u tat ur OD is ON and the panel is reminding u to turn it off...it works on the reverse logic....my old altis also using the same logic display for OD.

I beg to differ. The default for Latio according to the manual is "OD on". Pressing the button on the "stick" essentially switches OD to off; the indicator light will be lighted. Pressing the button again restores to default (i.e. OD on); the indicator light goes off.

The "usage" section on http://en.wikipedia.org/wiki/Overdrive_(mechanics) gives very good explanation on the usage.

U r absolutely right...i just checked the latio owner's manual in my car....default is ON and by pressing the button you are turning it off..

eh correct me if i am wrong, so essentially pressing the OD button to turn if "OFF" that means we are actually shifting it one gear higher that would propel the car faster?

It's like dropping 1 gear to get into the power band so that you can accelerate faster.

To propel the car forward at a faster rate, u drop gear...this is the time when u see ur rpm cheong up and the engine working hard sound....this will burn more fuel but give u more power...

OK, I hope to clear up the confusion pple have with this OD thingy.

By default (meaning no lights/indicators showing on dashboard display) - OD is on. And this is the recommended setting. It means your car is able to go to the highest gear, hence theoretically highest speed for the same engine RPM.

If you press the OD button, something will be lighted up on the dashboard - that means OD is off. The light on the dashboard regarding OD is a warning light (like the door-open light, hand-brake light, high beam light on the dashboard). So, it is a warning that your OD is off, and you should set it back to "on" unless you are sure OD "off" is what you want (just like high beam light).

So, when should you set OD to off? My personal opinion is that you should only set OD to off when you are climbing a slope, AND find that the gearbox is shifting up and down without settling on a particular gear. Because when the gearbox shifts up, there is not enough power to go up the slope, and the gearbox will shift down to provide more power, then find that the RPM is high enough to shift up, then tries to shift up again. So, to prevent the gearbox "hunting" for the correct gear to go up the slope, you should set OD to off to prevent it shifting to the highest gear resulting in insufficient power and then shifting down again.

Hope that clarifies things.

As you may notice, I was only talking about AT cars generally. I have no idea how relevant this OD/SPORT thingy is with CVT cars, because CVT cars generally don't suffer from this "gear hunting" problem.
You also should not think that having OD off lets you accelerate faster, because it doesn't. It just prevents the use of the highest gear. To accelerate faster, for most modern AT cars, you just depress the accelerator harder to make the gearbox shift down.

Experts, correct me if you find anything wrong about the above. I'm still learning as well.

Agrees =) I tried it personally and find that by turning OD off does not allow one to accelerate faster.

In fact, i tried to do it once when my car is around 80kmh and the effect is the same as a manual car changing from 4th to 3rd gear. It's different from Honda Civic "S" gear, where it makes the car "revvy" and powerful (which i love it)

Have a question .. how do we know that the gearbox is "hunting" for the correct gear to go up the slope? For manual car, when we feel no power, we simply down a gear.

Post by: CustomGolf on October 10, 2008, 10:17:18 PM
Auto Box hunting means it switch down and up very quickly, like when you're going up slope and it just drop gear after a short acceleration, it switch up to loose power again then down again, Didn't experience it in the Nissan as much as my last ride, but when I loose enough power to feel that the car is not responding to my stepping in the accelerator, I hit the OD button. Most often going up shears bridge from beach road.
