Also, the low gear box setting is best for when alot of torque is needed, normal (the middle setting) is for normal driving, but what situations would warrant the high setting (not high gear, but the high setting- does that make sense? I don't know if I've explained it properly?)? Thanks! |
The high gear (4x4) is used in normal driving on slippery roads, such as when there's snow on the roads but you can still drive at reasonably fast speeds.
The medium gear (4x4) is used when you need to drive in thick snow or mud and must keep your speed relatively slow.
The low gear (4x4) is used only in extreme situations such as going down a
very steep and
very slippery hill and you want to use the engine RPM instead of the brakes to control your speed.
Driving in 4x4 mode on dry pavement will cause rapid wear on the drivetrain due to the fact that the wheels are locked together to the same rotation speed, which isn't what they necessarily want to do all the time.
