Excellent technology: A prerequi-
site for your driving pleasure
For your Porsche to achieve its full driving potential,
the vehicle requires your attention and care.
Checking the vehicle for damage and correct
functioning
A vehicle with technical issues may be the cause of
accidents due to faulty operating behavior, for
example.
e Check your vehicle regularly (at least once a
month and prior to long trips) to ensure it is free
of technical issues. Pay particular attention to
the following:
– Undamaged tires, correct tire pressure and
sufficient tread
– Operation of headlights, brake lights and turn
signals
– Undamaged aerodynamic components
– Intact windshield wipers
– Windshield and window glass is clear and
free of cracks or other damage
– Door and interior mirrors are intact and cor-
rectly adjusted
– Sensors and cameras are intact without any
flaws or damage
– Cooling air ducts, sensors and cameras are
not obstructed (e.g. with film, stone shields
or license plate holders)
e Only operate the in-vehicle telephone or radio
equipment with installed radio antenna using the
connected external aerial so that the threshold
values for electromagnetic radiation in the ve-
hicle are not exceeded.
Checking tires for damage
Damaged tires may burst while driving. You may lose
control of the vehicle.
e Inspect the tires as often as required depending
on use, but at least once a month, for any foreign
objects that may have entered, pricks, cuts,
tears, or dents. Check the tire sidewalls in the
process.
e If in doubt, have the tire and the entire wheel
checked by an authorized Porsche dealer.
e Do not continue driving with damaged tires.
Have damaged tires replaced immediately: Visit
an authorized Porsche dealer, as they have
trained technicians and the necessary parts and
tools.
Safety and Driving Pleasure
Setting the right tire pressure
Too low or too high tire pressure destroys the tire
and wheel, extends the braking distance, and signif-
icantly increases the risk of an accident. If the tire
pressure is too low, there may also be a noticeable
increase in fuel consumption.
e Adjust tire pressure in accordance with the tires
fitted and the load.
> Please see chapter "Technical Data" on
page 327.
> Please see chapter "Wheels and Tires" on
page 300.
e Ensure that the settings in the Tire Pressure
menu in the multifunction display correspond to
the tires fitted on the vehicle and the current
load of the vehicle.
e If a red tire pressure warning appears on the
multifunction display: Stop immediately in a
suitable place and check the tires for damage. Do
not continue driving with damaged tires. If nec-
essary, repair damage using tire sealing
compound.
