Note| t | Restrictors with a modified hole have been installed at the factory since November 1997 (yellow-coloured). The capacity was increased by 50 g for vehicles with a yellow-coloured restrictor. |
| t | In order to distinguish between the different restrictor versions, the one with the smaller hole is coloured yellow (1.54 mm) or red (1.42 mm). The restrictor with the larger hole (1.83 mm) is not coloured. |
| t | If a vehicle is fitted with a yellow-coloured restrictor as replacement for a non-coloured restrictor, add 50 g more refrigerant (see table). In addition, the capacity specified on the label in the vehicle is to be checked and amended if necessary or the existing label is to be replaced with one indicating the correct capacity (affix over old label). The red-coloured restrictor is not to be used for these vehicles. |
| t | Exclusive use was made at the start of production of „Zexel / Valeo“ air conditioner compressors. As of Model Year 1996, production was gradually switched to „Denso“ air conditioner compressors → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual) and → Electronic parts catalogue. |
| t | The logo of the compressor manufacturer „Zexel“ attached to the air conditioner compressor was modified from „Zexel“ to „Valeo“ from year of production 2006 onwards (change in manufacturer's name). |
