Hi Houssayn
What is the build date of your vehicle?
R01 (transmission) is pertinent to vehicles with build dates within June 17th 2013 and December 1st 2014. It's considered a 'Customer Satisfaction' flash so if you are experiencing shifting issues and your vehicle falls between these dates then you should consider having it done.

R05 (airbags deploying when your Jeep happens to be at a weird angle
) Your dealer has this update. As Lujabe has recommended, talk to them - perhaps have it done when you're in for your first 10,000kms service (unless you are intending for some very serious off-road experiences prior to this).
