Light will not go off

Your vehicle may be equipped with low oil pressure engine protection. If so, that issue may need addressed first. Low oil pressure sw cuts off fuel pump, saving engine from catastrophic failure.

That depends on the type of oil warning light being displayed. There are 2 types of warning lights

1. Low oil pressure light which all cars have
2. low oil level light which some cars have.

Low OIL PRESSURE warning means the oil pressure is below minimum and when this happens there will be insufficient lubrication of many engine parts because sufficient oil cannot get to all parts of the engine it is required to lubricate. Until the cause is identified and rectified the warning light will remain. If you run your engine with low oil pressure you will cause expensive damage to internal engine components.

Low OIL LEVEL warning means the oil in the sump has dropped to a dangerously low level (which may be due to an oil leak or abnormal oil consumption by the engine.) This warning means the oil level needs to be topped up and the warning will stay displayed until you top up the oil. Running the engine with low oil will cause expensive engine damage.
Since it is a 2 minute job, Oil levels should be checked fortnightly as a minimum, together with radiator coolant and power steering fluid levels, if you run the car most days each week as most people do.

It is possible for a warning light to remain displayed when the cause has been dealt with because there is a problem with the sender unit. However it needs to be established with alternative checks that the problem has been fixed before investigating if there is a problem with the warning light itself.

You will need to read the codes to determined the reason the check engine light is on.
Acura Service Codes

A: Replace Engine Oil
B: Replace Engine Oil and Filter. Inspect various systems and components

1: Rotate Tires and check tire pressure and condition
2: Replace air cleaner element, check drive belt and replace dust and pollen filter
3: Replace transmission fluid and transfer fluid (if equipped)
4: Replace spark plugs, replace timing belt (if equipped), inspect water pump, and inspect value clearance
5: Replace Engine Coolant
6: Replace rear differential fluid (if equipped)

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.

The rear seal of the engine could have started to leak but a loose oil pan or damaged oil filter could be a factor.

The low washer fluid light could be the sensor in the tank, and the low tire pressure could be a problem with the ABS system.
Check your owners manual on resetting the tire pressure light.

It is the same for any mercedes. here is a copy from another source on the internet

Just change the oil/filter.You may of set off low oil indicator.After change if check engine light is still on.Have local parts store check diagnostic codes

Because of changing outside temps this happens, just hold reset button on left side of dash until it reads tire pressure 100% again, just make sure your pressure is right before you do it. this is the same for oil changes and the like.
