How do you put a 1991 suzuki sidekick into four wheel drive?

Step 1, Ensure the front hubs are set to lock. In the centre of each front wheel is a dial. You have 2 options FREE or LOCK. Lock is for 4wd, Free is for 2wd. Step 2, Using the clutch move the small gear stick, between the front seats to Either H4 or L4. H4 enguages 4wd and keeps the gears the same as they are usually, ie highway driving. L4 or Low 4 enguages a whole new set of lower gears designed for tough, slow off roading.
