Just got a 2004 Buick Rendezvous CXL and we just went into Daylight Savings Time. I have searched though the manual and can't find how to change the hours on the radio's clock.
Push and hold the H button four the hours to change and push and hold the M button to change the minutes. You just have to hold them in until the numbers change.
Jeff's solution is correct.
To quote the manual:
"Press and hold H until the correct hour appears on the
display. AM will appear for morning hours. Press
and hold M until the correct minute appears on the
display. The time may be set with the ignition on or off.
To synchronize the time with an FM station broadcasting
Radio Data System (RDS) information, press and
hold H and M at the same time until TIME UPDATED
appears on the display. If the time is not available from
the station, NO UPDATE will appear on the display.
RDS time is broadcast once a minute. Once you have
tuned to an RDS broadcast station, it may take a
few minutes for your time to update."

Think you have to reset it manually unless its a radio controled clock

Vous avez besoin de regarder dans le manuel du propri?taire.
SOURCE: Fuel line after the filter
well if thats a sure thing all you need to do is buy the part from dealer or aftermarket, then relieve the fuel pressure by pressing the little valve that looks like a tire valve stem on the fuel rail which will release fuel pressure, disconect negitive battery terminal, and then all you need to do is remove old line and replace with new line, you will need some fuel line disconect tools which can be purchased, this is the best pic, the release valve is on the fuel rail there and ou take the cap off and press on valve 
SOURCE: how do you change spark plugs in a 2002 buick rendezvous cxl
When you change spark plugs make sure your engine is cold, if the engine is hot you have a chance of breaking the ceramic the plug is covered with. Go to your auto parts store and buy some spark plugs. Ask the auto parts clerk what the plugs need to be gapped at or you can have them do it. When ready to change plugs, again make sure engine is cold. You will need a ratchet, possibly an extention and a spark plug socket. Pull the spark plug wires from their hole each individually as to keep track of which wires go to what hole. Put your ratchet, socket and spark plug socket together and insert in hole. Turn the ratchet left as the saying goes righty tighty, lefty loosy. Pull plug from hole when all the way loose, put new plug in and tighten snugly and put wire on new plug. Repeat all these steps on other plugs.
