Minimum speed for cruise control

No going to happen. It needs to be at a speed fast enough to get engine and tranny RPM into a range it can work with. YOu could fool it to work by installing lower axle ratio which would increase RPM at same road speed but this is a expensive fix.

Why do you have a 1997 Jeep Grand Cherokee 5.2L Limited in Holland? Manufacturers have determined that cruise control is unsafe under 35 mph. Your casualty and liability insurance company would have a fit if you made this modification, got into an accident, and put in a damages claim. They might even refuse to cover you, think about that.

Have you asked a Jeep dealer if that can be set with the programmer? In the U.S. 35mph is considered the lowest point at which cruise control can be safely used.

What difference does it make why he has it?

I suspect that the reason it's considered unsafe to use cruise at those speeds is because here pretty much anywhere you are going that slow either it's a congested area or the driving conditions are so bad you shouldn't be using it.

The situation may be quite different in the Netherlands.

Last time I was in Holland, all they used were bicycles, billions of bicycles:

In my experience, most cruise controls will engage at 35+ mph. You can then decellerate as low as you wish by pressing the decel or coast button several times until it cruises more slowly.

I'd like to remove the limits on my Wrangler as well, leaving only an RPM limit. This would make it easier to concentrate on the terrain when moving slowly, rather than concentrating on RPM or speed.

Do YOU really need cruise control at twenty miles an hours????????? God Bless America, Bill O|||||||O mailto: snipped-for-privacy@aol.com

Not so, I've had multiple cars that would set the cruise control at

25mph and who's owners manuals say it will work at 25mph. That includes Ford, GM, Chrysler and imported vehicles, my '93 Jeep GC is the ONLY car I've ever driven that required 35+ mph to use the cruise control with the exception of a 2002 Jeep GC and a 2007 Jeep GC.

I don't know if it's a Jeep thing but it's sure true of GCs.

I don't know where they're getting it, either. I've NEVER driven a car that required more than 25 mph to set the cruise except Jeep Grand Cherokees.

Hello All,

It is clear to me that the Jeep is one of the few with the 35mph minimum. I myself have also driven other cars which can be set at lower speeds than 35. So i'm not worried about my insurance. I don't like to change the axle ratio(suggested by snoman) as this will be bad for fuel economy. Other option already suggested by the local garage is changing in the computer the size of the tires. Dis-advantage of this is that the speedometer will be incorrect.

So i'm still hoping for a smart technician who can explain which board to change, or even that i have to solder a different type of resitor on a board.

Regards, Jos

My '05 TJL requires min. 35 to engage. Most other vehicles I've owned had a threshold of 25 mph. All would let you cut the speed back below the threshold once CC is enabled.

Our TJ that we just traded had to be at 35 or 40 for the cruise to work. We had a Dodge Caravan a while back that was the same way and stated such in the Owners Man.. No cruise in the JK but we also have a Mazda MPV van that the cruise will work at 25. I use it a lot in the city where we have a boulevard with a 30 MPH limit but the lights are synched so you can travel the length of it without having to drop the cruise out. I always cursed the TJ while driving there (the Caravan too) because I couldn't use the cruise control at that speed. Must be a Chrysler thing. Les '07 JK 2 Door X

In the Commonwealth of Virginia, the speed limit in residential areas is 25 mph, unless other wise posted.

I love to set it at 25 (both my '91 Chevy truck, and the wife's '05 Liberty will do it) and lead a convoy of mostly high-school kids out to the main road in the mornings. Makes things safer in my neighborhood.

I believe all residential areas are 25 MPH, but that doesn't mean I kick back and cruise, as the area implies children chasing balls or just wondering into the street from behind parked cars. God Bless America, Bill O|||||||O mailto: snipped-for-privacy@aol.com

Interesting thread. I would never have thought and will never use cc on local roads/streets.

FWIW, my LandRover and my Rover SD1 didn't/don't kick in until 40 mph
