The best way to switch on the wipers of the Tivoli is to leave it in the setting as shown in the picture. This lever can be found on the right side of the steering wheel.
The switch on the left of the lever should always be left on AUTO as shown below. This means that your wipers will automatically engage once it is drizzling/raining. The speed will be automatically adjusted according to how heavy the rain is.
To activate the wiper at the back, turn the switch on the right side of the lever up once for low speed, and twice for high speed. Do remember to switch this off once you are done.
In order to use the water jet spray in the car, just pull the same lever towards you for a quick jet spray.
