Welcome to the forums Michal,
It is the Airbag Warning Indicator lamp?
This is controlled by the RCM (Restraints Control Module) and, as you have found, a 'hard reset' does not clear the warning. Only finding and fixing the fault will clear it.
As a newbie, you cannot download the Workshop Manual from the forum so here is the relevant section showing the components in the restraints system:
The only effective approach to troubleshooting the fault, as suggested by guy in post #2 is to have the error codes read.
One simple thing to eliminate is circuit voltage. If your battery is suspect or partially discharged, this can set code B1A0016 which illuminates the warning lamp.

Hello Graham.
Yes, this is light which is stil on.
Thank you very much for tour advise.
For a moment I don't know the error code (concessionnnaire didn't tell me).

Hello Michal,
If you can get the code(s), post here and I'll look up the decode for you.
Finally I obtained report of diagnostic of my Jaguar.
There are lot of codes. For me this is a "magie noire".
I dan't know which code shows rho problem with air-bag control.
I join the report.
Thank you very much for your help
U015500 - lost communication with Instrument Cluster
U300087 - RJB missing message
U300055 - RJB incorrect configuration data received
U040181 - ECM/PCM invalid input signal
B1B7700 - front RH blend stepper motor actuator fault
B1B7600 - front LH blend stepper motor actuator fault
B1B7500 - panel/foot stepper motor actuator fault
B1B7400 - defrost stepper motor actuator fault
B1B3364 - target ID transfer signal plausibility failure
B1C3494 - steering column telescope solenoid unexpected operation
B100D96 - column lock authorisation low voltage
B1B0167 - key transponder start control unit invalid response
U300055 - stored vehicle configuration data does not match
U300049 - Instrument Cluster internal failure
U200531 - missing vehicle speed message ABS module or Instrument Cluster
B006164 - passenger seat belt tensioner
U300362 - battery voltage mismatch with navigation control module
Battery has caused a number of the errors and there is only one (B006164) directly connected to the restraints system.
Nothing in the list indicates a simple (low cost) possible cause and suggests the problem, if not a failing battery, is either Instrument Cluster or RCM (Restraints Control Module).
I had intermittent air bag light coming on last year.
I didn’t get a code read out so wasn’t sure what was causing it.
It seemed to start when I started putting my electric golf trolley on the passenger seat.
I removed the passenger seat and checked all of the plugs and sockets were not loose.
Lamp still came on occasionally without anything on the seat.
I looked into possibilities that the seat occupancy pad was faulty.
I might add that I rarely had anyone seated in the passenger seat so the sensor which I believe is just a pad/bag in the seat with a sensor in it was never really used
so I made a point of taking a passenger .
All seemed OK after that so my theory which could be rubbish is that the occupancy sensor needed a reset by someone sitting on it. Been 9 months now with no air bag light👍
It was suggested ,it could have been on this forum , that if you have a smallish weight on the passenger seat then the system turns off the airbag assuming that there maybe a child sitting on it and lights the lamp as a warning.
I couldn’t find out that if this was the way it should work, certainly not in the manual.

You have to be extremely determined to find it.
Not well proof read by JLR. The word airbag is missing from the phrase 'the appropriate ....... will be deactivated'.
I find the deactivation warning comes on if I put the fairly heavy Sunday papers on the passenger seat.
Thank you very much indeed Graham.
I will change the battery first.
Michal
Michal,
Make sure that your new battery is fully charged before it's installed. Many brand new batteries aren't fully charged because they sit on the retailer's shelf for months.
A low battery causes many electrical gremlins. It's a common problem and the first thing to check. If your XKR is not your daily driver, you should keep it on a battery maintainer.
Thank you very much for yours advises.
The battery has been changed last Friday (it was long time to get an appointment at Jaguar in Cannes ) and miraculously all of errors disappeared.
Everything seems be ok.

Michal,
Pleased to hear it was a simple fix.
These vehicles are very sensitive to battery condition and charge. Using a battery tender will help prevent future similar problems. Most of us use one of the CTEK range,
