To get you out of the toughest spots, all models of the new Toyota Hilux are equipped with Rear Differential Lock. If you’re on a slippery surface and one of Hilux’s rear wheels is spinning, Rear Differential Lock assists the low-ratio L4 mode to give you the extra traction and control needed to keep moving.
Discover how to use Rear Differential Lock in our short film, or read on below for more details.
Rear Differential Lock can only be activated when Hilux is in low-ratio L4 mode – for instructions on how to activate L4 mode, see this post.
To engage Rear Differential Lock, make sure that Hilux is travelling less than 5mph and that the wheels are not spinning.
Push the switch to activate Rear Differential Lock, and gently press the accelerator. If possible, drive with the steering wheel turned. The dashboard indicator light will flash and stay on when the system is locked.
As soon as you regain traction, disable Rear Differential Lock by pressing the switch again and continue on your way.

why hilux revo diff lock speed is limited to less 5mph..
Because diff lock is beneficial only when you need absolute traction and torque when your vehicle is stuck in the mud. If you can go more than 5 mph then you’re not stuck. Also if you use diff lock when going more than 5 mph, you will have hard time controlling your vehicle because it tends to go in straight line. You also risk the chance of breaking expensive drivetrain components.
Diff lock won’t disengage what can we do 2017 model
Diff lock is on H2 H4 and L4 and no matter what we do it will not disengage. Being careful not to damage transmission and tried disengaging in reverse, full lock and in all driving modes but nothing. We did remove switch as there was a leak through the o ring so not sure now if we have upset it’s set up on reassembly

I cant find anywhere if disengaging diff lock can be done while driveing, or if the car must stand still.
Same with disengaging L4, must be in Neutral, or while driveing?
car must stay still. wheels have to be stopped.

Hi I have a 2003 Toyota Hilux the when in 4l and press diff lock button the light comes on the dash diff lock engaged. However when stuck the light flashes and one rear wheel spins out all the power so it’s not engaging! What’s wrong here? No bad mechanical sounds
Hello Josiah,
Thanks for your comment.
As we’re sure you can appreciate, this isn’t something that we are able to diagnose virtually.
We would recommend visiting your nearest Toyota Centre for further assistance.
Thank you.
In new Hilux is automatic track control working also when rear differential is locked ?
I read the manual and the answer if NO. So when rear differential is locked the A-TR does not work. My question now is why ? Anybody knows why ? Thank you.
Hi Gary,
That is correct. When the rear differential is locked, the rear wheels can only turn at the same speed so traction control cannot work.
But don’t worry, because this locked differential provides traction in off-road conditions.
This is a tried and tested system, and is what makes the Hilux so good off-road.
Thanks.
When activating my diff lock on a the new 2021 model the light flashes a few times then goes out, surely the diff lock should stay lit up when activated. Is this normal or is there something wrong with my new Hilux ?
Hi Paul,
Congrats on your new Hilux!
It sounds like the read differential lock isn’t activating.
The Rear differential Lock can only be activated when Hilux is in low-ratio L4 mode, and when it is travelling less than 5mph and the wheels are not spinning.
Push the switch to activate Rear Differential Lock, and gently press the accelerator. If possible, drive with the steering wheel turned. The dashboard indicator light will flash and stay on when the system is locked.
Try these things, and if it still doesn’t work, please contact your nearest Toyota centre.
Thanks
I have a Toyota Hilux Vigo and the diff lock green light flashes non stop. I have tried pressing it on & off nothing happens.
Hi Silvia,

We can only advise on UK specification vehicles, so we would recommend contacting the Toyota distributor in your region for further assistance.

Hi sir
Dose a 2008 hilux 3.0 invincible has a read differential lock? I’m looking to buy one but the owner can’t find it.
Hi Danny,
Thanks for your interest in Hilux.
Rear differential lock is standard on all Hilux models.
Thanks.
Hi, We have 2018 Toyota Hilux Active. 4H engages fine, but when we put in 4LO, light start flashing and its not engaging. Can you please help.
Hi Mudassar, thanks for your comment.
We would recommend contacting your local Toyota Centre so that the technicians can view your vehicle in person.

Thanks.
Hi. Can you confirm: When changing to 4Low, are any diff locks automatically engaged; Central or Front/Rear?
If not: there shouldn’t be any risk of damage to the system if using on a hard road surface at low speeds, whilst turning corners – Right?
Hi Dave,
Please provide your vehicle registration so that we can check this for you.
Thanks.
Hi. Looking at a 2019 Active Extra Cab. Or if the diff lock does automatically engage, which model year does it not?
Hi Dave,
Our Technical Team have advised that the front diff has a lock called Automatic Disconnecting Differential (ADD) which will engage with 4H. 4WD should only be engaged on a loose surface such as snow or mud,etc. There may be slight differences between specification, so we’d need the exact details to provide further information.
Thanks,
Toyota UK
