When / how to use 4wd

[Lightyear66]

Folks

I have this good guide on when and how to use 4wd, and it all make sense to me apart from L4L

When do you use L4L ? How does it differ from H4L ?

3rd Gen: The 3rd Gen Surf has a multi-mode 4wd system.

It may be used in 2wd Hi-ratio, driven by the rear wheels only, 4wd Hi-ratio with an open centre differential. 4wd Hi-ratio with the centre differential locked and 4wd Lo-Ratio with the centre differential locked.

H2: Rear wheel drive only: Normal operation, best for less wear & tear on components, best fuel economy & performance.

H4: 4 wheels driven, open centre differential: Press red button on side of 4wd selector. 4 wheel Indicator will illuminate in centre of dash when fully engaged. You may select/deselect this mode at speeds up to 100Kph. May be used anytime extra traction is desired

H4L: 4 wheels driven, centre differential locked: Move 4wd-selector lever fully back (position of button on side not important), 4 wheel Indicator and centre diff light will illuminate in centre of dash when fully engaged. You may select/deselect this mode at speeds up to 5Kph. Must only be used on loose surfaces such as mud, snow etc.

L4L: 4 wheels driven, centre differential locked, Lo-Ratio engaged: 4 wheel Indicator and centre diff light will illuminate in centre of dash when fully engaged. Select neutral on main gearbox, move 4wd selector-lever fully back, push to the right and then forwards.

Quite obvious really!

Low ratio engaged L4L,
I take it you know what low ratio does???

Thank you for your reply.

"Quite obvious really" - Very helpful......Don't worry I have had a Google but was really hoping for a real world comment from someone offering their experience to the in-experienced.

Low-ratio gearbox.

A gearbox suitable for normal driving is not ideal for tackling extreme conditions like steep hills or very soft ground when off-roading. Consequently off-road cars are often fitted with a second, lower-ratio gearbox which means better traction. Low ratio is normally engaged by a second lever next to the main gear lever and turns the wheels slower, reducing the risk of losing grip.

So you did'nt know what low ratio was all about!!

By the way,wind your neck in a bit,that kind of attitude won't get you any fans around here!!

Low ratio is only to be used at traffic lights.

Engage 4low, left foot on the brake and right foot to the floor on the accelerator.

Don't wait for green, go earlier because the Corsa that you are racing will have a weight advantage.

And you could have made a small effort and just suggested when and why it would be used. If you had read what I originally posted you would have seen that each description suggested a usage for each selection.

I merely pre-empted your next useful suggestion of "do a search".

But thank you for your suggestion.

Why am I having this conversation????

Use l4l for Steep off road descent, keeps it under better control so you dont need to brake meaning you dont lock up, skid and then speed up. Having the centre diff locked help traction on slippery surfaces but dont use it on the road.

Not all 3rd gen's have multi mode.

Philip L4L gives you the maximum torque at the slowest speed. It will give control on descents and accents, the truck can however still slide on a wet/slippery decent if its steep enough so not full proof by any means.

In short:
Perfect for situation where loads of 4x4 grunt is required with the ability to stay in control and at low speed

H4 open does not exist on a non multi mode

Perfect - thank you

Thank you yoshie and muddle.

That is perfect....That is all I was asking for...A simple explanation of when and why for a novice Surf owner.

Many thanks and best regards.
