Abstract
An instructing system for a four-wheel drive vehicle powered by an internal combustion engine comprises a transmission for transmitting power from the engine to two main driving wheels, a clutch for selectively transmitting the power to auxiliary two-wheels, and a select lever for engaging the clutch. Speed detectors are provided for detecting both the speed of the two main driving wheels and the two auxiliary wheels. An electric circuit compares both speeds and turns on a lamp when the difference between both speeds exceeds a predetermined level, whereby slipping of the two main driving wheels is indicated.
