WARNING
The filling couplings for the natural gas refuelling systems can be of various different designs. Please ask for assistance from trained personnel if you are unsure of how to use the system.
Noises which you may hear while refuelling are normal and do not indicate that the system is malfunctioning.
The natural gas system in your vehicle is suitable for use with small compressors (slow fill) and large compressors (fast fill).
Things to note: At very high ambient temperatures, the overheating protection function for the natural gas refuelling system could switch off automatically meaning the normal capacity will not be achieved.
