1. Adjusting Tire Pressure for Full Passenger & Luggage Load
Check the B-pillar placard for the heavy-load row (4–5 passengers + luggage). Inflate all four tires cold (before driving more than 2 km) and always check the trunk spare wheel — temporary space-saver spares require 4.2 bar (60 PSI) and lose ~0.07 bar per month.
