This procedure is particularly difficult for those doing the job at home because some of the fasteners to be uncovered are hidden, there are some awkward angles that need to be worked on and there are a number of electrical connectors that need to be labeled and disconnected. It is better to do it in a dealership or any other recognised shop. It will be useful to pay a lot of attention when some of the parts are being uninstalled, where they are placed and how they are held, since all this will be vital when reinstalling the part. It is not required, but both front seats when unbolted offer more working clearance and protect the seats from accidental scratches. First, you should take the air conditioning system to be discharged by the help of a professional. Remove battery cable-sump terminal, drain the coolant and separate heater hoses at the heater core. Disconnect all refrigerant lines to the evaporator core and it is advisable to plug all the lines so as not to cause any contamination. Disconnect the heater module from the dash and remove the center console and all trim panels in the dash, and pull off all the IP connectors, if you need to. Take the steering column switches out of the car, move the front seats back as far as they can go, unbolt the steering column and let it drop down to the floor. Then, take out the brake pedal assembly, body control module, centre support bracket, shifter assembly and the mounting bolts of each ends of the instrument panel. Take out the floor heat ducting, pull the instrument panel back as far as it will go and disconnect any interfering electrical connectors. After all the connections have been unbolted, the instrument panel can be lifted out with considerable force to free it from the windshield; it should be removed through the driver side door if possible. Reinstallation however is carried out in the reverse order of removal.

Take out the instrument cluster retaining screws.
