cruise control and now cruise control and A/C quit by peakoil

On the highway a couple months ago my super '04 gave a little jolt and the cruise control popped off and wouldn't reengage. The triangle with the exclamation point, the engine with the half circles around it, and the engine with "check" warning lights came on at the same time. I called a Toyota garage who said "bring it in", and hadn't heard of this before. I then called Toyota regional and asked them. The guy said "nothing important, it'll be okay next time you drive. Just a minor glitch." Whoa!. Next day the lights were still on, but the cruise control reengaged on the first try. After a few miles the three warning lights went off. Frugal me didn't bring the car in.
 
Yesterday it happened again. However, this time both the cruise control AND the A/C compressor went off and stayed off. (Its 90 plus in Sacramento today). The fan kept fanning. All else is fine. Anybody heard of this one, and if "yes", what was the fix?

My experience with the Sylvania Silverstar replacement headlight bulbs was somewhat less satisfactory. I put them in my '02 VW Passat, and was somewhat pleased at first. They were NOT the difference between "night and day", but they "seemed" a little brighter/whiter to me.
Several months passed, then one headlight failed. I tried to replace the bulb, but was surprised to find the female electrical connector had melted and fused together with the bulb itself. As a matter of fact, the wiring was melted back about an inch from the connector and the insulation was GONE.
Since I was unable to "unplug" the bulb from the connector, I was dismayed to find that VW offered only a COMPLETE headlight ass'y ( $$$ ) as a replacement part for the melted wiring and connector.
Fortunately, my experience as a M-B mechanic provided me with a safe and reasonable "way out". I ordered replacement connectors from the M-B parts department and repaired the melted wiring on BOTH headlights.
I now have "normal", factory headlight bulbs back again in my VW and hope never to forget the lesson life has taught me concerning "super duper" replacement light
bulbs.
My '07 Prius ( pkg #6 ) came equipped w/HIDs and I have had to replace only 1 headlight bulb ( under warranty, 3 trips to the ?Service? Department ), so far.
Incidentally, my 30yrs experience as a M-B mechanic also taught me that the ML was, at the time, the very worst vehicle that M-B ever produced for sale in the US.
That vehicle has been superceded by the W211 E-Class as the very, very worst Mercedes-Benz EVER produced for US clients/customers!

Steering wheel - control lights? by salwitz

I just bought a 2009 Prius (5/1/2009) and the controls on the steering wheel don't appear to be lighted. Is this correct? They look like they should light up based on the material that they're made of. I looked all through the manual and couldn't find anything on this.
 
Thanks,
Ken

My '07 lights up, but very, very dimly.
It has to be pitch dark to see them. The dash lights are blindingly bright in comparison.
I consider this a "shortage" that Toyota has given me due to the fact that they are so dim, they are hardly visible.
With use, you will be able to hit the right button at night. It just take time to familiarize yourself with their placement. And if you have the Navi system, you can use voice commands for some of the features. Meanwhile, "practice makes perfect".
I also consider the lack of a glovebox light(s) a "shortage".
A rear dome light would have been nice.
The lights in the bottom of the doors when they are open are nice, but perhaps lights in the dash vents was considered overkill.
Armrest storage compartment light(s) must have been overkill too.
 
I really like my Prius, but the "furnishings" and appointments are just a tad Spartan for me. But then it IS a gas mileage kinda car.

Well I checked with another guy at the dealership service center and he said no they don't illuminate at all. So much for that undocumented feature.

Well, mine do, but I have an '07 with a pkg #6 everything ). BUT they are so very dim, that unless you are in a dark, dark place you have to concentrate to see them.
It's note really worh taking your eyes off the road. You will get used to them, and one day ( night ) you'll see them.

My Owner's Manual sez remove the cover between the grille and the engine. It is held on w/six plastic "rivets". After that you can snake your hand down to the headlight and remove the cover, then the connector, and then the bulb. My car has HID lights, but yours may have halogen. DO NOT TOUCH THE GLASS ON THE BULB! It will prematurely burn out if you do. Also, removing the fusebox cover may help too.
GOOD LUCK!
