Smart key warning light

What it means

A no-key message after START/STOP indicates that the matching smart key is not detected inside the vehicle. Flashing after START/STOP indicates a low key battery in this edition.

What to do

Read the displayed message and check that the matching key is inside. Distinguish key detection from a flashing key-battery indication before following the corresponding key instructions.
