Have you checked your fluid levels recently?
Can you describe the noise a little more?
Rattle, knock, squeal, howl etc?
I'd say about 300-500ml if it is halfway on the stick.
Would you hear the noise across the road, as a neighbour might?
How many kms on the engine?
Can you top up the oil when you get a chance?
If it is not an accessory drive belt squeal, then it could be a bearing knock in the engine before oil pressure develops.
Or does it sound like a fan going flat out?
How long has this noise been happening?
Is it safe to drive? A bit hard to say until we can determine the sound.
Does it drive normally other than the noise at startup?
Do you need any further help?
I hope my advice has been of assistance to you.
