Brake Light. Make sure you are not driving with hand brake on. Check brake-fluid level. Top off brake fluid if low and make appointment to check brakes. Driving with brake light can be dangerous; deal with this soon. Call tow truck or drive carefully and slowly to shop.
ABS (antilock brake system) Light. Indicates either low brake-fluid level, stuck brake caliper or faulty ABS. Check brake fluid and make appointment to get brakes checked. Call tow truck or drive carefully and slowly to shop.
Oil Light. Either engine is very low on oil or there is no oil pressure. Pull over and turn off engine immediately. Check oil level and add oil if low. Turn engine back on to see if light has gone off. If oil light is still on, bad oil pump (no oil pressure) is likely. Call tow truck.
Check Engine Light. Car's computer senses engine problem. Difference in performance may not be noticeable, but make appointment to have car diagnosed. This usually cost around $65-$75 to do. OK to drive. If problem is serious, computer may switch to limp-home (low-power) mode and you won't have option of waiting to bring car into shop.
Air Bag Light. Get air bags checked. Problem could prevent them from activating in accident. OK to drive, but not safe in accident.
Battery Charge Light. Alternator is not charging. OK to drive, but turn off any unneeded electrical devices (radio, heater, defroster) and avoid starting engine more than necessary. Bring car into shop soon to avoid getting stranded. When alternator is not charging, battery loses charge and car stops working.
Emissions Lights (O2 sensor, EGR, check emissions). Depending on car model, these lights may indicate problem with emissions sensor or may light up at certain mileage, usually 60,000 miles (100,000 km). Get sensors checked. OK to drive. If problem exists, car might get poor gas mileage.

If the "service soon" is turn on, this is a warning about "maintenance time" (filter and fluids change); this warning light isn't the same that "check engine".

Hope helps.

The change oil light needs to be reset after each oil change...some shops are not knowledgeable on how to do this...Your owners manual will instruct you how to reset the oil change light...The service engine soon is a catch all for low fluids and other needs...Be sure to check your oil level again...to clear the service engine soon light, you can disconnect either battery cable for 15 minutes then reconnect...if the service engine stays on...then you need to have your Grand Am checked...Auto Zone does a free diagnostic of check engine light codes...:)

will try to help.the shaking during braking may be a warped brake rotor,shaking while driving is in the wheel alignment. you have several issues to deal with.as far as the engine light flashing,check all your fluid levels in the engine. oil,low coolant, brake fluid,transmission fluid. top off fluids as needed. you can reset that engine light by disconnecting the positive cable from the battery for 10mins.this will reset the cars computer. but if you have a sensor or other issues,that light will come back on.the only way to know for sure is to have it code read a garage or dealership will be able to plug it in to get the codes for you.hope this helps and thank you for choosing fixya.com

the ser soon light is a maint thing and can be reset if all maintance has be done the other symbol could be low coolant or low washer fluid check all your fluid levels frist.

How to reset (erase the light):
Open the fuse access panel on the driver side. Youll see a small rectangular red button labeled RESET.
Turn ignition ON
Press the RESET button repeatedly until you see the SERVICE ENGIN light flashing on the dash.
Press and hold the RESET button for a few seconds until you hear 5 'dings'. It will turn off.
Turn ignition OFF.
Drive safely.
Good luck.
Please rate the solution....

I would guess there is a relation between the inop speedo and the service soon light being on. Push OFF and WARM on the climate control panel and hold down together for 5 sec to read codes.engine and transmission require speed input to set engine/trans parameters accordingly. The car car is safely performing in a back up mode until repairs are made
