Selective Catalytic Reduction - SCR (AdBlue®)
Too low AdBlue level
If the AdBlue level is too low, the vehicle cannot be restarted after the ignition was switched off. It is also not possible to jumpstart or emergency start the vehicle.
Irritating and corrosive fluid
AdBlue is an irritating and corrosive fluid that can harm skin, eyes, mucous membranes, and respiratory organs.
AdBlue corrodes surfaces such as painted vehicle components, plastics, clothing and carpets.
Appropriate AdBlue refill containers can be obtained from an authorized Porsche dealer.
For information on warning messages on the multi-function display:
In vehicles with selective catalytic reduction (SCR), a special urea solution (AdBlue) is injected into the exhaust system ahead of the catalytic converter in order to reduce nitrogen oxide emissions.
AdBlue is stored in a separate tank of the vehicle and should be refilled under normal driving conditions during service according to the maintenance schedule. The AdBlue tank holds approx. 5.02 gallons (19 liters).
AdBlue consumption depends on the individual driving style, system operating temperature, and outside air temperature. Therefore in rare cases AdBlue may have refilled between service events.
Starting with a remaining range of about 1,500 miles (2,400 km), a reminder to refill AdBlue is displayed on the multi-function display. If you ignore the last refill reminder, it is impossible to start the engine again after it is switched off.
We recommend that you have the AdBlue tank refilled by an authorized Porsche dealer. If no authorized Porsche dealer is available, you should refill at least 1.5 gallons (5.7 liters) of AdBlue (3 AdBlue bottles). Refill only the type of AdBlue that Porsche has explicitly approved for your vehicle.
If the red or yellow warning message appears in the multi-function display, there is a malfunction. Porsche recommends that you take the vehicle to the closest authorized Porsche dealer.
