My1991 mercedes benz 300ce has trouble starting up?
Recently bought the car, battery is about 3-4 years old, has trouble starting up

For 1991, the Mercedes-Benz 300-Class models bore a lot of resemblance to those of the previous year. The majority of the models came with a 3.0-liter, 6-cylinder, single-cam engine that generated 177 hp, while the 300CE coupe came with a 3.0-liter, 217-hp engine. The 300SL convertible stepped it up just a bit with a 3.0-liter, 6-cylinder, 228-hp engine.
A 4-speed automatic transmission was standard across all models, with the exception of the SL, which came with a 5-speed automatic overdrive. A sunroof was also standard equipment on all models (again with the exception of the SL). Other standard equipment included antilock brakes, power windows, power door locks, air conditioning, and airbags for the driver and passenger.
Leather seats were standard on the 300E, SE, SEL, and E 4MATIC sedans, on the SL convertible, and on the CE Coupe. They were available as an option on the other models.

1991 e300d. opened rear doors and worked the light switch several times to no avail. Is there a manual over-ride somewhere? I feel it will eventually run down my battery if the light doesnt burn out first. I really want to repair it. ..
I have a 1991 300ce24 valve and when you start it ,it splutters and misses for a short time and will conk out sometimes but once it evens out it will run smooth all day long and takes the reves and plenty of power. is it a fuel or electronic problem?
The light came on for the 4MATIC.
