Notes:  
     
Zexel A/C compressors were installed from 
start of production. During m.y. 1996, 
Nippondenso type compressors are installed as 
a running change. These compressors are not 
equipped with A/C speed sensor G111. 
     The A/C control head is coded to reflect the 
compressor type installed (Zexel or 
Nippondenso). 
     Vehicles equipped with Nippondenso (Denso) 
compressors must have A/C control head with 
Part No. index "H" or higher installed to allow 
for correct coding. 
     Follow coding exactly when replacing an A/C 
control head -E87-.

m.y. 1999 for vehicles with and without radio 
navigation system (or a radio with a large 
control panel), with and without switch for 
heated seats (e.g. index "M", "N", "P" or "Q").
