My clk roof light come on after every time I drive the car, and I have reset it by takeing battery terminal off, when the light is on I can not uses the window and boot luck , why is that happing

If you have a Code scanner you can do it there.. if not, Unplug the Battery Positive and Negative terminals for 5 minutes then Reconnect.. it will reset and check everything..

check the adjustment of the roof position switch /sensor . If it is activated then the switch/ sensor may be faulty.

Looks like a failed relay:
"I sat in the car and started pushing the roll bar button. We heard a click every time I pushed it. My brother was at the back of the car and was trying to hear where the clicking was coming from. He realized it was coming from a relay switch so he took a screwdriver and tapped the top of the relay and **BAM** everything starts working! So through that we realized it was a bad relay".

there should be a key in the glove box or in dash, insert in the centre of the roof near the windscreen and twist the roof will open then you need to lift the back part of the roof up and away from the boot then open roof storage compartment and push the roof down into place.

INITIALIZATION
1. INITIALIZATION OF SLIDING ROOF MOTOR
(a) The sliding roof AUTO operation and the jam protection function may not operate normally if the battery
is disconnected/reconnected, replaced or recharged. Initialize the sliding roof system using the method
below.
(1) Turn the ignition switch ON.
(2) Initialize the sliding roof by pressing and holding the TILT UP switch until the roof glass tilts upward
fully (the roof glass automatically tilts downward slightly after fully tilting upward).
(3) Release the switch.
HINT:
If the battery terminal is disconnected, the moon roof control ECU may not detect the position of the roof
glass. If the sliding roof AUTO operation is still disabled even after the sliding roof drive gear has been initialized,
the hall IC may be malfunctioning. The hall IC is built into the sliding roof drive gear and detects the
roof glass position.
If the result is not as specified, replace the drive gear assy (moon roof control ECU).

hi, unfortunately this is one of them how longs a piece of string things, you could purchase a code reader reset the error code but, what you have to think of is what caused it to do it in the first place, accelerating to hard should not cause an error ( i do it all the time in my car lol ) but it might be related to the 02 sensor getting to much unburnt fuel passing it which would cause the engine light to come on, though if the car is running as normal i doubt that will be the issue, i would myself on a car like that take it to the main dealer and get them to check it out, as buying an inexpensive code reader might not cut the mustard with this one, and parts being as dear as they are for merc's i would play on the safe side, spend a few bucks to save a load...sorry not much help

first be sure that its the engine light and not the "service" light. the service light will usually illuminate if its time for an oil change. if its the service light ur owners manual should tell u how to reset it. if its ur engine light then try disconnecting ur positive battery cable for 1 minute. that should reset ur ecm and get rid of the engine light. if the engine light comes back on then have a diagnostic scan done to determine whats causing it.

They can check the battery and the charging system for starters. Fully charged battery,clean cables. then do a load test on the battery. If it didn't pass the test replace it and check the charging system.
Charging system easy to check , Put voltmeter on battery terminals and monitor vehicle's voltage with and wthout accessories on. should be between 13.5 to 14.5v . Before condemning alternator inspect wiring behind alternator ...if corroded replace then retest.
If voltage is with range then the problem is in the power distribution compartment/ relay, or either is a ground all those items share.
