itsrelfy

hi
i have recently bought a 1991 honda civic gl as a first car and it didnt come with a handbook. there are severla things i dont know about it.
When i bought the car i was told it had central locking but i cant get it to work. Before i bought they replaced the battery is there anything i need to do to set up the central locking again

also what oil does the car take eg is it 15w-40

and one more thing i have an alarm on the car there is a lock in the glove box you have to turn and i have a handset to disarm it but can i arm the alarm with the handset as well.

Please help if you can

Any help would be greatly appreciated.

cheers
Adrian
