Smart key warning light

What it means

A no-key warning after pressing START/STOP means the matching smart key has not been detected in the vehicle. Flashing after pressing START/STOP indicates a low key battery in this edition.

What to do

Read the accompanying message and confirm the matching key is inside. Distinguish key detection from a flashing key-battery indication before following the applicable key procedure.
