It says 4WD but it’s really more of a AWD vehicle. Under normal conditions it’s FWD until it detects slippage and then can send power to the rear wheels but it’s more FWD biased 70% front 30% rear. With the 4WD Lock button engaged it just distributes power more equally between the front and rear. It’s like 55% front 45% rear with the 4WD Lock engaged.
Why would you turn off 4wd if the brakes are tapped? If you're stuck in snow, you're going to tap the breaks here and there, but FOR SURE want to stay in 4WD!
the car is permanently in 4wd. '4wd lock' is a differential lock. it locks the central differential so an even amount of torque is supplied to all wheels. you use it in situations where you don't have enough traction to progress.
@@greenjay8096its not in constant 4WD. Its FWD bias, only when the front wheels slip then it activates the Rear wheels to help push. Then when the front stop slipping the rear wheels deactivate to go back to FWD. The Diff lock, locks all the wheels so you get all the wheels moving all the time up to a certain speed and when you go past that set speed it will cut off or you can turn it off yourself. Its not a true AWD system like a Subaru or a 4x4. A Subaru has all the wheels powering the vehicle all the time. And a 4x4 you can put it in 4hi and power all the wheels together.
Does this mean the car is an 'ALL WHEEL DRIVE' (all the time) Unless you turn on the 4WD LOCK SYSTEM Then the power is distributed equally to front and back until you hit 25 mph . My Son and I keep have a disagreement about this!! He keeps saying it's not an "All wheel drive" vehicle????
Gypsy G its a Part-time 4WD, the Lock button is the rear differential Lock, you cant go at speeds and turn while all wheels turn the same its for when your stuck or doing "offroad". The Part-Time 4wd will engage when needed but is not the same as the Differential Lock. Hope im not mistaken🤷🏻♂️
It's only an all wheel drive vehicle when it needs to be, i.e the car detects that the wheels are slipping it will turn on all 4 wheels, but normally when you are driving it only uses 2 wheels
The rear wheels are always "activated". It's a full time 4wd. They're just not locked, and they're not locked between left and right wheels even with the diff locker turned on. The locker only locks between the front and back axles. It's not a proper 4x4, but it's better than a 2x4.
Trust me, you don't want your diff locked at high speeds. You'd destroy the drivetrain or crash. The brakes also don't properly work if the diff is locked, so its turned off if they are used.

I have RAV4 2009 September version. However it seems the the 4WD button first has no mark on it and then it I can't press it. any reason?
I think your car probably doesn't have the feature
It's because your one is a 2WD model
Why would you turn off 4wd if the brakes are tapped? If you're stuck in snow, you're going to tap the breaks here and there, but FOR SURE want to stay in 4WD!
It's so the ABS and the VCS turn on correctly

Why the rev4 drive slow up the hill
C'est à Combien ?
Good lord!!! Too confusing!!! I just want to know is how to tell if the rear wheels are actived with out getting stuckto find out!!

@@ioanbugheanu6836actually its normally fwd car, center “lock” sends powr to rear
Turns off at 25mph? Thats some bull, also if the brakes are tapped it turns off, also stupid...
i mean its a rav 4
Agreed, stupid design.
