Found this interesting and some great tips.

Found this today thought it would be helpfull to some.

C5 Secrets and Computer CODE

The little yellow "helper light" on the bottom of the rear-view mirror that illuminates the shifter area

That you can put your key in the driver's door and turn it twice towards the front to unlock the passenger door and a third time to pop the trunk.

That you can pop the trunk and also pop the gas cap cover by pulling on metal lines hidden in the back.

The little slotted cover on the dash behind the steering wheel is where the inside air temperature sensor is located.

All of the option codes are in the glove box.

Tire inflation recommended pressures are on the driver's door

The thing that looks like a little LED near the DIC buttons is a light sensor

The thing that looks like a little LED near the defroster vent is a UV sensor for determining A/C usage to compensate for the heating effect of the sun

The build sheet is in the front re-bar

If you leave your turn signal on, in about 1 minute it will start to ding (loud enough to hear over the stereo) to let you know you have old timers disease.


You can reset the oil life by pumping the gas pedal 3 times (but not with the engine running)

Hold down the reset button while on one of the trip odometers and it changes that reading to the miles you've traveled since last starting the engine.

Hold down the Active Handling button for 5 sec. to engage "Competitive Driving" on cars equipped with active handling (2000 and previous years must be stopped.)

If you pull the seatbelts all the way out while you're buckled in, they ratchet back in to hold you tighter into the seat.

Simply remove fuse #2 under the hood and your DRLs will be out permanently. Only thing affected is that when you unlock at night using the key fob your front turn signal lights and back up lights will not will not flash. Your front turn signals will operate normally, however.

The side-view mirrors can twist both forward and backward, decreasing the chance of damage if struck.

There is a release opening with a flap to let air out of the car when the hatch is closed. It is located just above the driver side rear compartment, behind the carpet and on the side of the car. Not that it really works well.

Also you can ground your amp to a screw/bolt that holds the rear middle compartment to the frame.

If you have a 6-speed car you can pop the trunk when the car is running by lifting the e-brake.

There is a spot on the driver side just out of the middle compartment under the carpet for the lug nut key. You should have a compartment on the drivers & passengerÂ's side (in the trunk) and a center compartment. On the left (drivers) side of the center compartment, on the left side where the center cover fits, there is an 'indent' that holds the wheel lock key.

If you turn on the headlights, then go to parking light position, the lamps remain up but the headlights are not left on.

If you have the passive entry feature: If you lock your keys in the car, wait a few minutes and then shake the car. That will unlock the car.

HUD has a shift light for manuals.

You can easily shift the M6 trans up or down without the clutch if you match revs. (Not great for longevity, however.)

You can eject the cd from the in-dash player without turning on any power. Don't even need key in the ignition.

The cruise will disengage if you purposely make sharp side to side turns while cruising at say 60-80 mph.

When the engine is shut off, you can get the odometer reading by turning on the parking lights.

You can program setting #3 (both memory buttons atonce) in the seat memory to run the seat back and steering wheel forward for getting in/out of the car with the engine running.

If you hate DRLs you can pull the e-brake ONE click and they go off

Excellent post, however I may need clarification with where the re-bar is located.

They do actually use rebar in bumper supports in a lot of cars. Just sayin...

There must be a list of secrets and 'easter eggs' for the C6 too.

I'll see if any of these work and then hunt around.

With our 2005, the GM manual says "To reset the CHANGE ENGINE OIL message after an oil change, do the following:
1. Press the TRIP button so the OIL LIFE percentage is displayed.
2. Press RESET and hold for 2 seconds. OIL LIFE REMAINING 100% will appear."
If I hadn't received the owner's manual with this car, I would have been totally lost. When we first picked up the car, I stopped in at the first gas station I came to. Then it struck me...how do I shut this thing off. Fortunately, my first guess worked. Secondly would have been brake and clutch to snub it. :( :D I still haven't read up on the active handling, traction control stuff. Perhaps I should. At my age, the old reflexes aren't what they used to be and I need all the help I can get. :rolleyes:

These days the owner manual is invaluable. Lots to read up on and learn.
My C6 Oil Percentage resets the same btw. I'm glad GM kept it simple.

Funny, the first time I went to fill up my car after buying it, it must have taken me 10 minutes to find the release for the fuel door. Who knew it was in the center console!? The manual did.:rofl:
