Start with the handbook rather than the badge on the tailgate.
Four-wheel-drive systems differ in how power is distributed and how the driver selects modes. A control with a similar label can behave differently across vehicles. Read the handbook for your model before using an unfamiliar setting.
Separate the vehicle's capabilities from the conditions around it. A traction system does not remove the need for suitable tyres, careful observation or a route appropriate to the driver. Understanding a limit is more useful than assuming a feature will solve every problem.
Make a short reference note for routine questions: the manufacturer's tyre guidance, permitted operating modes and where to find warning-light information. For a fault or an unfamiliar behaviour, ask a qualified professional rather than experimenting in difficult conditions.
