Fiat Linea T-Jet: Abnormal RPM Behavior at Starting

[Navin Talati]

Dear Friends,
Your valuable guidance is earnestly invite in this issue with my Liea T-Jet.
When I start the car, the engine RPM (as per odometer) goes to about 1300 rpm and after 1 or 2 minutes it sets to its normal value of 750 +/- 50 rpm.
Afterwards it remains normal.
What may be the cause of this behaviour and how to resolve it?
Kindly help for this.

Its normal.

Its a warm up function programmed in ECU.

Dear vishnu,
The car has clocked about 53K KM. This behavior is observed only since Sept-2018. Previously it was not happening. --- means this is not a normal behavior in this case.
Please guide.
