Closing the tank filler neck

Put the collapsible spare wheel back in the spare wheel well and secure it with the fastening screw A and washer B.
Close the loadspace floor panel.
After refilling, switch on only the ignition.
Leave the ignition switched on for at least 30 seconds so that the system can detect the refill.
Do not start the engine for 30 seconds.
Store AdBlue safe
Store AdBlue only in its closed original container and in a safe place.
To reduce the risk of poisoning, never keep AdBlue in empty food or beverage containers that might mislead someone into drinking from them.
Always store AdBlue outside the reach of children.
Tires and Wheels
The original equipment tires and wheel rims on your Porsche comply with all applicable Federal Motor Vehicle Safety Standards.
For your safety remember the following:
Wheel rims and wheel bolts are matched to fit your Porsche.
If you intend to use other than original equipment wheels, be sure that they conform to Porsche specifications for your model. Only tires with the same make and with the same specification code (e.g. "N0", "N1"...) can be mounted.
The use of wheel rims and wheel bolts that do not meet specifications of the original factory installed equipment will affect the safe operation of your vehicle and affect warranty coverage.
Before you plan on exchanging wheels, or snow tires already mounted on the wheel rims, consult your authorized Porsche dealer.
Your dealer has the technical information
necessary to advise you which wheel rims and
wheel bolts are compatible with the original
Tire Damage While Driving
Driving with damaged tires could cause you to lose control of the vehicle.
If while driving, your vehicle experiences a sudden vibration or ride disturbance, and/or you suspect that possible damage to your tires or vehicle has occurred, you should immediately reduce your speed without excessive use of the brakes.
Stop the vehicle as soon as possible, and inspect the tires.
If you cannot determine the cause for the disturbance, have your vehicle towed to the nearest Porsche or tire dealer to have your vehicle or tire(s) inspected.
Continuing to operate the vehicle without correction could result in a loss of control.
