The volume of the tank on your Yeti is 8,5L.
The remaining autonomy in miles appears on your dashboard once the level of AdBlue® is below 1500 miles. A signal on the minimum and maximum quantity of AdBlue® to fill also appears. Once you fill up with AdBlue®, turn on the ignition for at least 30 seconds before starting the engine so that the fill up is detected by the system and makes the signal disappear.
When the red warning light appears instead of the signal to show that you are out of AdBlue®, you will not be able to restart the engine once you stop it. Find a place to buy AdBlue®.
This information can vary on some vehicles of the same model in relation to the options chosen by the manufacturer.
