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.

  • Refill AdBlue when the AdBlue fuel range falls to about 600 miles (1,000 km).
  • Never let the AdBlue tank run dry.

Irritating and corrosive fluid
AdBlue is an irritating and corrosive fluid that can harm skin, eyes, mucous membranes, and respiratory organs.

  • If AdBlue gets into your eyes, flush them thoroughly with plenty of clean water for at least 15 minutes; medical attention is recommended.
  • If AdBlue is swallowed, immediately rinse the mouth with plenty of clean water for at least 15 minutes. Do not induce vomiting unless instructed to do so by a medical professional. Get medical attention immediately.


AdBlue corrodes surfaces such as painted vehicle components, plastics, clothing and carpets.

  • Remove spilled AdBlue immediately with a wet cloth and plenty of cold water.
  • Remove crystallized AdBlue with warm water and a sponge.


  • Use only AdBlue that has been explicitly approved by Porsche. Using other types of AdBlue can damage your vehicle's engine.
  • Never mix water or any other substances or additives with AdBlue. Damage caused by such additives will not be covered by any Porsche limited warranty.
  • Never put AdBlue into the diesel fuel tank. Otherwise the engine may be damaged.
  • Do not carry a refill container in the vehicle all the time or routinely. Due to temperature fluctuations and damage, the container could start leaking and the AdBlue could damage the vehicle interior.

Information
Appropriate AdBlue refill containers can be obtained from an authorized Porsche dealer.


Warning messages
For information on warning messages on the multi-function display:

  • Please see the chapter "OVERVIEW OF WARNING AND INFORMATION MESSAGES" on page 140.

AdBlue information
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.

Refilling AdBlue

  • When refilling AdBlue, the vehicle must be parked on a level surface, not on an incline or with the wheels on one side up on the curb. If the vehicle is not on level ground, the gauge that shows the fill level may not register the added quantity.
