I drive a mid-size 2.7L SUV with automatic overdrive and AWD. My commute takes me up steep hills and over mountains. I'm not sure of the grade on any of them, but many have truck lanes to allow slower vehicles to move over as the climbs can be tough and sometimes lengthy. In a situation like that, is it best to let the cruise do the work for the engine or let the driver control the rate of accelleration?

i own a repair shop,and its never a good idea to use cruise control on real steep hills ,it can cause a lose of control in some cases ,and also if a car decides to pull out in front of you as your gaining speed ,you might not be able to stop as quick ,,i wouldn't use it in situations like this,it would be better if the driver was in control of the car,,good luck with it i hope this help,s.,,have a good x-mas.

going up the hill it really doesn't matter. Going down the hill is where you'd have problems. You see, climbing isn't the issue with steep grades unless you are hauling or towing, but stopping or slowing down going down steep grades can get you or someone else killed.
At any rate, play it safe and don't use the cruise in this particular situation. It's safer for you to be alert and in control than to hope your car knows what's best for you in terms of acceleration.
BTW, enjoy your Liberty.

IT be ok to let the cruse control do the work, IF you dont have the speed set to high where it will shift down to a very lower gear and rev. the engine above 4000 rpm for to long of a time.. be best to set the speed so engine dont over rev.

Use your Cruise any time. it truly is not undesirable on your brakes. Older autos (1998 and decrease than) use a vacuum servo. This controls the speed that your vehicle runs on cruise. once you've a vacuum leak the vehicle will surge. (randomly rev). many times a vacuum hose or a leak contained in the servo.

If your engine sounds like it's laboring, or you slow down below your pre-set speed, the cruise control should be disengaged. If it's handling the grade OK (keeping up to speed without sounding odd) then it's all right to leave it on.

I prefer to control acceleration both uphill and downhill. I like to control the shifting, be it a double stomp on the long skinny pedal in an automatic, or working the tree in a manual.

the cruise control increases the throttle based on demand so leave it on ( on a steady grade it will hold uphill speed better than you can - as the engine note changes people tend to press harder on the gas - bet you find yourself having to watch the speedometer to hold a steady speed )

it doesn't matter if its cruise control or not- a constant speed is the same to an engine whether you press the peddle or have cruise control on.

the best thing to do is to let the driver take over
