Thanks for the link, identified them. They are the locks for the top radiator support.
I only got my car last week, have not timed it. The delivering Nissan dealer has recommended (insisted?) that engine speeds be limited to <3500rpm in the 1st 500k and then <5000rpm in the next 1500km. Is this BS ? Has anyone else been advised of this ?
With my other cars I have caned (nicely though) them since after 200 or 300 km, no issues.
