RPM jump when stopped on an incline?

[Burgi]

I have 13k miles on my 24 Tacoma. In the last couple days I noticed that whenever I’m stopped on an incline, my RPMs jump up to about 1100rpm. Usually when I’m idling on flat ground it’s around 500 rpm.

has anyone else noticed this? What could cause this?

Hi,

It's an incline hold feature when the transmission is in drive it raises ther idle to keep you from rolling backwards when you transition from brake to throttle on a hillside. It's in the owner's manual.

interesting. Does this apply to the automatic transmission?

 

[Captain O]

Yes. The automatic transmission does it when the truck is pitched uphill.

definitely makes sense. I just poured over the manual and cannot find it. What section is this in?

says it has to the with the brake, nothing about increasing the RPM

How steep of an incline are we talking about? Yes I’ll absolutely pay attention

Like 10+ degrees or so. The TRDs have a menu in the display that will show you pitch and what kind of angles you're sitting at. Not sure if the SR5 also has this.

My sr5 has that feature too . I stop on a decent incline going home daily but I’ve never heard the engine idle up while in drive stopped. I’ll check tonight
