Grateful for any advice on effecting a hill start with an electronic handbrake. Having to hold with the footbrake after releasing the handbrake seems a risky business with the car potentially rolling backwards - particularly if there are vehicles behind!
-
Doesn't it release automatically when you press the accelerator and let the clutch out?
-
read up hill hold assist in the manual, someone correct me if I am wrong just going by my model
-
The electronic handbrake releases automatically so no need to hold on the foot brake. Just pull away as normal and the handbrake will release automatically.
Hill hold assist is useful if you haven’t engaged the handbrake. Holds the car on a hill for 2-3 seconds allowing you to pull away without rolling back.
-
The hill start initially I Did not think much of it but using it for 3 months or so I love it . takes the balancing on the clutch and brakes out of the equation
-
Apologies but have been out of the country for a while and only just read replies to my earlier post. No, the handbrake does not disengage when I let in the clutch, hence my original query. The car has autolock which works correctly.
-
I also have the odd occasion when the E Brake does not disengage when I
try to drive away- this is on a flat surface.
Have to do manually, by applying footbrake & releasing E Brake switch.

I no longer have my CX-5, have a 6 Tourer now. It’s an auto and the EHB releases automatically as I pull away.
It was the same in my previous CX-5 manual. Engage first gear, pull away and the hand brake released automatically.
If it’s not doing that, it may there is a fault that needs checking out?
My dealer replaced the rear callipers on my CX-5 under warranty because the EHB sometimes stuck on a bit, making for a jerky get away. It was better after that.
By the way, the driver’s door has to be closed and the driver’s seat belt fastened before the EHB auto-release mechanism will operate.
It’s all in the manual - page 4-102 I think.
-
Thanks; certainly I'm belted & all doors shut when this happens.
-
It's page 4-85.

My CX-5 is an auto so I can't be certain... but I'm pretty sure that for the auto release EPB to work in a previously owned Toyota you had to release the clutch AND press the accelerator. Perhaps this is also the case with the CX-5?
-
Sorry to bang on about this but I am thoroughly confused. My CX5 has autolock, should the handbrake disengage as the handbook states (by releasing the clutch and accelerating) whether or not the autolock has been activated?
-
Sorry, could you explain what you mean by “autolock” please?
-
Mea culpa, I of course meant "autohold"!
-
I don’t think I ever manually activated autohold and I can’t actually recall if it was something you COULD activate manually? I know my car had autohold because it wouldn’t roll back for a couple of seconds when I released the footbrake on a hill.
The handbrake DID release manually when the accelerator was pressed and the other conditions were met (engine running, drivers door closed and drivers seatbelt fastened)
These systems would appear to be related but I don’t think one depended on the other.
If you EHB doesn’t release automatically as described above, I would get it checked out if it were me. As it’s a 2017 model, it will still be under warranty
(I had the same car as you except it was a 2015 model in black)
-
Thanks Ant, the car is booked in for a service next week so an opportune moment to have the handbrake checked, and as you say it is still within warranty. I have to manually engage autohold and have discovered that the handbrake will release easily whilst this is engaged, if it is not the handbrake will only disengage if I press down on the accelerator with some weight.
-
I was on a slight slope earlier, seat belt on, and I depressed clutch to drive off, but e brake stayed on;
I then got a message on dash in red, that I needed to release e brake.
I know now that I just have to press footbrake and release e brake.
