Question

Quizplus · Accepted Answer

Technician A is correct because 4-low mode provides increased torque at the wheels, which is useful for off-road conditions or when pulling a heavy load. Technician B is incorrect because 2-low is not a common feature on most 4WD vehicles; typically, vehicles offer 4-high, 4-low, and 2-high modes.
