Is anybody able to explain the precise difference between the three 4WD modes (Eco, Auto, Lock)? The manual gives a brief description, but it doesn't really tell me what I want.
Here's what the manual says, essentially:
Eco - For economical driving, usually 2WD, but 4WD according to wheel slip.
Auto - For automatically controlling the distribution of driving torque to all four wheels according to driving conditions.
Lock - For driving in slippery conditions.
But this leaves some questions:
1 - Does Lock lock the front & rear differentials, and/or the front & rear axles together?
2 - What is the difference between Eco & Auto? Auto clearly doesn't lock fully since there is a dedicated Lock mode, so it must also require a certain amount of slip before locking up, so in what way does it differ from Eco?
