Releasing Cruise Control with Brake

jburns · 10-01-2009, 06:33 PM

I don't know how much of a problem this is but my Prius requires a firmer push on the brake pedal to disengage the cruise control than any car i have ever had. To the point that my bride, who is usually asleep in the passenger seat, has her head loll forward whenever I disengage cruise using the brake. This usually wakes her up and earns me a dirty look. I plan on having this checked out when I take it in for the first service but I am wondering if others have noticed the same thing or not.

My Prius IV does the same. I have to hit the brake harder than my 2007 or any cars before this one.

I have to press harder than before. i just use the off button.

ya this hapened to me too. i had CC set for 70 and due to another car i pushed the break( not too hard) . car slowed down and i took my leg off the break expecting the car to just coast . then i hear the ICE suddenly rev up and my speed increasing. i thought my my self Crap the Accelerater is stuck.when i looked at the display it showed that the CC was still in SET mode . so I hit the breaks a little bit harder and CC cut off.

On most US cars, the slightest touch of the brake pedal drops out of CC.

I wonder why Toyota did it differently?

No idea but it is not an improvement.

Yes, I've noticed this too. I am now getting used to pulling the lever forward to disengage the cruise control.

You can add mine to the list and I feel it is bordering on being dangerous in some situations. I've never had any car (and I've had at least 30) that have ever required anything more than the lightest touch on the brake pedal to disengage the cruise control. This is the only issue I have with the Gen III, and it is different than the Gen II I traded in. I suspect it may be the brake switch design or adjustment. I will ask the dealer to check when it goes for its first oil change.

Well, you're first engaging regen...so the cruise must not click off until you hit the part that is "full" braking. At least that's my guess. I haven't noticed a problem with it, but I don't use it that often. I find that I get much better mpg without cruise.

I agree. Definitely requires a harder application than my 2006 Prius. Just tap the stalk on the steering wheel. In any abnormal situation, one would be pressing the brake hard anyway.
