How Urgent Is the Door Ajar Warning Light?

In terms of priority, treat this as a low concern on your Alfa Romeo Tonale.

How to Fix the Door Ajar Warning Light on a Alfa Romeo Tonale

1. Open and firmly re-close each door, boot and bonnet
2. Identify which opening the cluster reports as open
3. Inspect and clean the suspect latch switch

Is It Safe to Drive With the Door Ajar Warning Light On?

Whether it is safe to keep driving your Alfa Romeo Tonale with the Door Ajar Warning Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Alfa Romeo Tonale is running poorly, stop somewhere safe and arrange help rather than pushing on.
