Chrysler Crossfire
Oil change and resetting the service alarm

This is one information page of my collection of what I have repaired on my Crossfire.

You should not do any repair on your car if you don't have enough experience and knowledge! You use this information at your own risk! Don't blame me if something goes wrong.


Crossfire share most of it's engine parts with Mercedes SLK R170 with the 320 engine.

Chrysler Crossfire, Oil change

Oil change and resetting the service alarm

Oil change:

This is not the SRT model.

According to the service manual you don't change the oil after how many kilometers or miles you have driven the car. The onboard computer system calculates when it's necessary. It depends on how long you have driven the car, how many cold starts, how often it's used and so on.

This is only about the oil, there other things that need service when the service alarm shows up too. Read carefully in your car's service manual !

When approaching the time for a oil change the service alarm start with a beep when you start the engine. It will also display instead of km (miles) the days left until the oil should be changed. I have also read that instead of display the days left it can display how long it's left in km or miles. I don't know why there is a difference.

In my case I got a service alarm after 15000 km (9000 miles), the service alarm started 30 days before the oil change should be done. If you don't get a service alarm when you have driven the car more then this you maybe shall change the oil even if there is no service alarm.

Chrysler Crossfire: Oil refill cap and Oil filter

You shall always change the oil filter too when changing the oil. Included with the oil filter there shall be three or four new O-rings (gaskets). You reach the oil filter from top of the engine. A lot of Mercedes models use this kind of oil filter.

Chrysler Crossfire: Engine plastic cover underneath

To get to the oil plug you have to dismantle a plastic cover below the underneath of the engine. To the oil plug there is a copper gasket, it has the dimension: 19.8 x 14.4 x 1.4 mm, it must always be replaced.

When you pour the oil out, do a check how it looks, if it's very dirty or grey because of water leakage. Take the car to a specialist for a check or repair. When reinstalling the oil plug, get a new gasket to it, mine was made of solid copper. Later when refilling with new oil, check for oil leakage before reinstalling the plastic cover.

According to my manual you shall have the following quality of the oil.

  • Mobil 1 SAE 0W - 40, only synthetic oil
  • Certified for MB 229.3 or MB 229.5

Check with your own manual also, if there is a difference, use the figures from your manual that belong to the car.

According to the manual it take 8 liter to fill the engine and oil filter. I bought 8 liter oil, but could only fill 7.5 liter until the oil stick indicate it was at correct level, check carefully, it's not good for the engine to overfill, of course too little oil also can destroy your engine.

Chrysler Crossfire: Oil stick

You find the oil stick in front of the engine, the red one.

Have the car in level, check the oil level, if correct and no oil leakage, start the engine and let it running for a short time, shut down engine and wait 5 minutes.

Chrysler Crossfire: Oil stick normal level

Check the oil level once again, maybe fill more oil, in my case I added 0.2 liter. Be sure to press the oil stick to bottom of the pipe, otherwise the level indication will be wrong!

Resetting the service alarm:

Now it comes to the tricky part, how to reset the service interval alarm. I had to do it three times until I succeeded to reset it.

Chrysler Crossfire: Service alarm reset button and display

You use your ignition key and the button where you reset the km meter (miles meter) by pushing the button. I follow this procedure, partly my own:

  1. Turn the ignition key to position II (the position III start the engine)
  2. Within one second push the button twice (reset button for km / miles)
  3. Km / miles meter display present status (days left), within 10 seconds turn the ignition key to off (lock)
  4. Press and hold the button
  5. Turn the ignition key to position II again
  6. Still hold the button
  7. After 10 seconds a signal sounds and it display 11000 km or 7000 miles for 10 seconds
  8. Release the button
  9. Turn the ignition to off, start the engine and check if the service interval alarm is gone (reset)

I must say this was a bit confusing to reset the service alarm and I hope the description above is clear how to do it. Anyway I got to reset it after some attempts.

This service alarm resetting procedure should work for Mercedes cars also, models C, CLK, SLK, E class, year about 1997 to 2004.
