The most common warninglights are:
Handbrake - Check whether you have removed the handbrake. This is the leftmost foot pedal on the Nissan Leaf.
Tire Pressure Light - Inflate the tires at a refueling or charging station and reset the tires.
Is there a red light? Stop driving immediately, take action if possible or call Hely.
Is it an orange light? You can continue to drive and report this to Hely via chat or firstname.lastname@example.org.
