How to use a 4wd gear

Use your gear shift as a pro

Drive a 4×4 is winning in safety, strength and confidence when transiting through difficult roads. However, how to activate the double traction or just know in what situations should be used may be a mystery to those who have no experience.

Here we solve the most common questions:

1. Why are there two levers?
Most have two levers 4×4. One handles the traditional gearbox, either manual or automatic. The second is the «transfer case» that defines the type of drive chosen by the driver as the road ahead. H is the High (High) and L is Low (Low).

2. What is H2 and what situations is it for?
The position H2 is commonly used. In this position the vehicle has traction on the rear wheels only. It is used in route, city and dry asphalt.

3. In what situations should use H4 and how active?
The H4 drive can be used on gravel, sand, wet asphalt, and any other situation where there may be loss of adhesion. To connect must pass the lever H2 to H4, it can be activated in motion, but should move in a straight line less than 80 km / h without depressing the brake pedal. It is not advisable to do so faster for the life of the transfer case.

4. Is there a speed limit on H4? How is disabled?
No speed limit for H4. To disconnect, it is only necessary to move the lever H4 to H2.

5. In what situations is useful L4 transmission?
The «low» or «reducing» provides more strength, more torque to the four wheels. It transforms into a little tractor. It is ideal for use in heavy mud, in sand dunes or if a trailer is necessary because it gives a lot of control to the truck. But to give a lot of strength takes speed, you can reach a maximum of 50 or 60 km / h. You can pass normally but changes will not take speed.

6. How L4 wheel drive is connected?
It requires the brake van. The main transmission must be in neutral (neutral automatic) and the gear box transfer to L4 moves.

7. How L4 is disconnected?
Again it is necessary to stop zero, place the transmission in neutral (Neutral for automatic) before returning to H2 and H4 as needed.
