Nissan Juke 2022-present Owners Manual
Hands-free Hands-free telephone control
Use a phone after stopping your vehicle in a safe location. If you have to use a phone while driving, exercise extreme caution at all times so full attention may be given to vehicle operation.
If you find yourself unable to devote full attention to vehicle operation while talking on the phone, pull off the road to a safe location and stop your vehicle before doing so.
To avoid draining the vehicle battery, use a phone only after starting the engine.
The hands-free mode can be operated using the telephone 
button on the audio system, or the 
button (where fitted) on the steering wheel.
