Apr 6, 2008 - 11 posts Next to the service engine light, orange with green triangle and upside down Y. Does anyone have the manual/know what this means?Missing: red ‎square

this is the tyre pressure warning light, indicating that one or more of your tyre pressure's is either to low or to high , so check the tyre pressures and it should go out , owners manual will give the correct pressure's for front and rear

Depending on your Model (and they do have many dashboard versions in '04 I believe). Hazard switches can either be located at the bottom of your Radio A/C console on a Red Triangle button two function, the right will be the one, or on the very top in a recessed spot just before the actual top left red triangle, for other models in 2004, just simply look for the Red Triangle on a black button? That would be-it!

In this case when you get the light blinking have your charging system look at,

low tire pressure warning lite

Hi, The exclamation point in triangle blinking is the "Emergency Blinker" This blinker turns on all all of the turn signal lamps at all four corners of the car. Left and Right, Front and Back. The triangle represents the European symbol for roadside emergencies. In fact on European Mercedes and other cars there is a triangle shaped reflector you can put behind the car so that other drivers know you have an emergency. THAT TRIANGLE ON YOUR DASHBOARD IS A BUTTON. PUSH IT ONCE. THE BLINKING SHOULD STOP. If you have a roadside emergency, and are broken down by the side of the rode. Push the Red Triangle and your lights will blink on and off ouTside to say, in effect "help".
Hope this helps.
Best,
