traffic situation allows you to do so safely. In
case of doubt, stop the vehicle.
e
Do not use a phone or other mobile devices
while driving.
e
Only make or receive calls using hands-free
equipment.
e
Do not reach between the steering-wheel
spokes while driving. Otherwise, you may not
be able to react in time to dangerous situations
in time.
Be aware of braking behavior in rain or
snow
In heavy rain, while driving through water or after
leaving a car wash, the brake disks are coated with
a water film, the braking action may be delayed
and increased pressure may be required.
Following a long drive over salted or gritted roads,
a coating may form on the brake disks and pads
that significantly reduces friction and therefore al-
so the braking action.
e
Dry the brakes by frequent braking, particularly
before you park the vehicle. This will prevent
corrosion.
e
Corroded brakes tend to "judder". If braking
comfort is noticeably impaired, have the brake
system checked.
Suitable tires and appropriate driving
style

Please see chapter "Wheels and Tires" on
page 278.
Reacting correctly to uneven running and
vibration
Damage to tires or the vehicle can cause uneven
running or vibration while driving. You may lose
control of the vehicle.
e
Reduce speed immediately, but without braking
sharply.
e
Stop the vehicle and inspect the tires. If a
cause cannot be established for the fault, drive
on carefully and have the fault corrected. Visit
an authorized Porsche dealer, as they have
trained technicians and the necessary parts
and tools.
Keeping tires in a safe condition
Damaged tires can burst, especially at high
speeds. Prevent damage to the tires by driving
carefully.
e
Cross curb edges slowly and at right angles if
possible.
e
Avoid driving over steep or sharp curbs.
Running in new tires
New tires have not yet achieved their maximum
grip and tend to slip.
e
Run in new tires at a moderate speed for the
first 125 miles (200 km).
Driving with snow tires
Maximum speed values apply for snow tires. If you
exceed the maximum permitted speed, the tires
may burst.
e
Always observe the maximum permitted speed
for the respective tire.
e
Affix the sticker with the maximum permitted
speed in the driver’s field of vision. Observe
country-specific regulations.
e
Set the maximum permitted speed as the
speed limit using the instrument cluster.
>
Please see chapter "Instrument cluster " on
page 125.
Driving with summer tires
Parking or maneuvering at outside temperatures
below 60 °F (15 °C) may result in noises.
e
Change to snow tires when outside tempera-
tures are below 45 °F (7 °C).
Assistance systems and their limits
Your Porsche is equipped with driver assistance
systems for driving comfort.
None of these systems can overcome the limits
set by the laws of driving physics.
e
These systems should not induce you to take
greater risks with your safety. The driver
