The glow plugs don't activate until the temp gets to about -5

In some 10 years owning C4s, I saw the glow plug warning lamp come on twice. On both occasions the temp was below -5°C.

The best advice is put the key in, switch on, wait 20-30 seconds for the pre-flight check to be carried out, turn the key and the car will start. Drive off ASAP.

Only once saw the light in 7 years with my original C4p. Not seen it in the past 4 years with the Airdream.If the engine smokes when cold then there are a few things to check. Always use a low ash fully synthetic oil and do not overfill the sump.
Check the air filter is not clogged and consider using an injector cleaner before each service.
