Note on operation
If the ignition key is withdrawn and the door is
opened while the lights (not the parking light) are
on, an acoustic signal (gong) warns of possible
battery discharge.
In some countries, differences are possible
due to provisions of law.Automatic driving light assistantThe driving light assistant is a comfort function.
Your Porsche’s driving light (low beam) is switched
on and off automatically, irrespective of the
ambient brightness.
Despite possible support by the driving light assis-
tant, it is the responsibility of the driver to switch
on the driving light using the conventional light
switch in accordance with the relevant national
regulations.
Activating the headlights using the driving light
assistant does not therefore absolve the driver of
responsibility for the correct operation of the
driving light.
The low beam is switched on automatically in the
following situations:
–Dusk
– Darkness
– Travelling through tunnels
– Rain (in conjunction with the rain sensor)
– Highway driving

When the wiper lever is released, a few drying
wipes are executed.Maintenance Note
fPeriodically clean the wiper blades with
window cleaner, especially after the vehicle
has been washed in a car wash.
We recommend the Porsche window cleaner.
In the event of heavy soiling (e.g. insect
residue), the blades can be cleaned with a
sponge or a cloth.
If the wiper blades rub or squeak, this may have
the following causes:
– If the vehicle is washed in an automatic car
wash, wax residues may adhere to the wind-
shield. These wax residues can be removed
only by using window cleaner concentrate.
fPlease see the chapter “WASHER FLUID” on
Page 258.
fPlease contact your authorized Porsche dealer
for further information.
– The wiper blades may be damaged or worn.
fReplace damaged or worn wiper blades as
soon as possible.

Setting Tire Pressure Monitoring
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire
pressure increases rate of wear of the
affected tires.
Despite the advantages offered by Tire
Pressure Monitoring, it is not a substitute for
proper tire maintenance, and it is still the
driver’s responsibility to update the settings
in the multi-purpose display and maintain the
correct tire pressure, even if under-inflation
has not reached the level to trigger illumina-
tion of Tire Pressure Monitoring low tire
pressure message. Low tire pressure
reduces the road safety of the vehicle and
destroys the tire and wheel.
fWhen a flat tire has been displayed, immedi-
ately stop in a suitable place and check the
tires for damage. If necessary, remedy the damage with tire sealant or fit the spare wheel.
fDo not by any means continue to drive with
leaking tires.
fSealing the tire with the tire sealant is only an
emergency repair so you can drive to the next
authorized Porsche dealer.
The maximum permitted speed is 50 mph
(80 km/h).
fDefective tires must be immediately replaced
by an authorized Porsche dealer.
Tire repairs are not permissible under any
circumstances.
fDo not drive with tires whose tire pressure
drops again in a short period of time. Have
tires checked by an authorized Porsche dealer.
fIf Tire Pressure Monitoring is defective (e.g.
defective wheel transmitters), contact an
authorized Porsche dealer immediately and
have the damage repaired.
The tire pressure will not be monitored by
defective Tire Pressure Monitoring.
For information on warning messages on the
multi-purpose display: Please see the chapter
“OVERVIEW OF WARNING MESSAGES” on
Page 149.
fTire Pressure Monitoring gives a warning about
tire damage due to insufficient tire pressure as
well as about a gradual loss of pressure due to
foreign objects. Tire Pressure Monitoring
cannot warn you about tire damage that
occurs suddenly (e.g. flat tire due to acute
external effects).
