I was installing a middle caddie by the gear shift and had to pull the plastic from the inner passenger side and found a hidden tire kit by the firewall on the passenger side ! Bonus !!!!
If you bought your car used, the previous owner used it. took it out of the car. Didn’t bother buying a replacement new sealant canister. All smart cars, were equipped, with the pump, and sealant can.My car came without it. Since I knew nothing about smart cars at the time of buying it didn't search for it. The piece of foam that houses the kit is entirely missing.
