The relays are accessible from the luggage compartment or after removal of small combination instrument.

On the 19 77 Models the fuse sequence has changed as follows:

1. The fuses 16 and 21 (fuel pump and window controls) have been interchanged.

2. The fuses 12 and 14 (sliding roof and rear window wiper or fan and rear window defogger) have also been interchanged. This was necessary to prevent the engine from running for several seconds after the ignition was turned off with the heater fan turned on.
