should be supplemented in the on-board
computer.
f Please consult your authorized Porsche
dealer.
f Use only tires approved by Porsche.
The available items in the tire pressure menu
depend on the equipment of your vehicle. For this
reason it is possible that some of the items shown
here are not available on your on-board
computer’s display.
f Make sure that tire pressures correspond to
the on-board computer settings. Correct the
tire pressure if necessary.
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on Page 277. Tire pressure warnings
The tire pressure warning light on the instrument
panel and a corresponding message on the on-
board computer warn about loss of pressure in
two stages, depending on the amount of pressure
loss.
Driving with insufficient tire pressure reduces the
road safety of the vehicle
and destroys the tire and
wheel.
Stage 1 – Add air
The pressure in the tire is too low by 4 to 7 psi (0.3
to 0.5 bar).
f The tire pressure warning contains the
affected tire with the tire pressure to be added.
Correct the tire pressure at the next
opportunity.

Warning!
Your vehicle has also be en equipped with a TPM
malfunction indicator to indicate when the system
is not operating properly.
The TPM malfunction indicator is combined with
the low tire pressure telltale.
When the system detects a malfunction, the tellta-
le will flash for approximately one minute and then
remain continuously illuminated. This sequence
will continue upon subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indi cator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended.
TPM malfuntions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPM from functioning properly.
Always check the TPM malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPM to continue to
function properly.
The warning light in the speedometer lights up:
– When a loss in pressure has been detected.
– When learning newly mounted wheels/wheel sensors, as long as the vehicle’s own wheels
have not yet been recognized. In the event of a defect in Tire Pressure Monitoring
or a temporary fault, the warning light in the
speedometer flashes for approx. one minute and
then remains continuously illuminated.
The tire pressure warning light in the instrument
panel goes out only when
the cause of the fault
has been rectified.
Partial monitoringMonitoring of the other wheels is continued if there
is a fault in one or two wheel transmitters.
– The tire pressure warning light lights up.
– The message “TPM partial monitoring” is displayed on the on-board computer.
– No tire pressures are displayed on the on- board computer for wheels with faulty wheel
transmitters.
No monitoringIn the event of faults the Tire Pressure Monitoring
cannot monitor the tire pressure.
The warning light in the speedometer flashes for
approx. one minute and then remains continuously
illuminated and a corresponding message
appears on the on-board computer.
Monitoring is not active when:
– the Tire Pressure Monitoring is faulty,
– wheel transmitters for the Tire Pressure Monitoring are missing,
– during the learning phase after the tire settings have been updated,
– after a wheel change without updating the tire settings,
– more than four wheel transmitters are detected,
– there is external interference by other radio sources, e.g. wireless headphones,
– tire temperatures are too high.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
f Before working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the PDK selector lever in position P or N . f
In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted in
the engine-compartment.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
f Your Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise ex-
treme caution when working on any part of the
engine while the ignition is on or the engine is
running.
f Always support your car with safety stands if it
is necessary to work under the car.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty cov-
erage.
f Supplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
f Some countries require additional tools and
special spare parts to be carried in your vehi-
cle.
