H2 Explained
H2 stands for “High 2-wheel drive.” It sends power to only two wheels. Usually, these are the rear wheels.

When To Use H2
- On dry, paved roads.

H4 Explained
H4 means “High 4-wheel drive.” It sends power to all four wheels at the same time.
This helps the vehicle get better grip on the road. It stops the wheels from slipping when the road is bad.
Why Use H4?
- It improves traction and control.
- It helps you drive safely on rough roads.
