Warning Light

Attention to TPM Malfunction Indicator

Your vehicle has also been 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 telltale 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 indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.

TPM malfunctions 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 alternate tires and wheels allow the TPM to continue to function properly.

The warning light in the instrument panel lights up:
– When a loss in pressure has been detected.
– In the event of a defect in Tire Pressure Monitoring or a temporary fault.
– When learning new fitted wheels/wheel transmitters, as long as the vehicle's own wheels have not yet been recognized.

The tire pressure warning light on the instrument panel goes out only when the cause of the fault has been rectified.

Overview of tire pressure monitoring functions
Tire Pressure Monitoring offers the following functions:
– Display of the actual tire pressure while the vehicle is in motion.
– "Fill info" display:
Display of the deviation from the required pressure (refilling pressure) at standstill.
– "Tire type" display:
Display of current settings (when the vehicle is stationary).
– Tire pressure warnings in two stages (yellow and red warning).


Tire pressure display on the multi-function display

Selecting the Tire pressure function on the multi-function display

The "Tire pressure" function displays the temperature-dependent tire pressures (actual pressures) in the four wheels. You can watch the tire pressure rise as the temperature increases while driving.

Information
This display is only for information.

Under no circumstances should the tire pressures be changed based on this display.

Viewing Fill info in the Tire pressure menu (only when vehicle is stationary)
You can read the tire pressures to be corrected in this display.

The tire pressure to be corrected (refill pressure) is indicated on the displayed wheel.

Example: If "–2 psi"/"–0.2 bar" is displayed for the front right tire, 2 psi/0.2 bar/20 kPa must be added to this tire.

The displayed pressures take into account the tire temperature.

Use only the pressure values shown in the "Fill info" display in the "Tire pressure" main menu or from the corresponding tire pressure warning when correcting the tire pressure.

Information
After the ignition is switched on, it can take up to approx. 1 minute until all tire pressures are displayed. Dashes (-.-) appear instead of the tire pressures.

Viewing current settings in the Tire pressure menu

Selecting load


Adapt the pressure of the tires to the selected load type.
See "Fill info" in the "Tire pressure" main menu.

Information
If this menu is not displayed, the specified tire pressures are valid for all types of vehicle load.

Selecting comfort/standard pressure
For speeds up to 165 mph (270 km/h), the tire pressures can be reduced to increase driving comfort.

The Tire Pressure monitoring must be set to the applicable tire pressure (comfort pressure or standard pressure).

If you select "Comfort pressure", the TPM automatically uses lower pressure values when monitoring tire pressure.

The comfort tire pressures are included in the technical data.
or
Under "Fill info" in the "Tire pressure" main menu, you can compare the pressure differences with the comfort pressures.

If the tires are not yet taught, the new required pressures are displayed instead of the actual tire pressures.

For information on teaching tires:

Please see the chapter "SYSTEM LEARNING" on page 109.

Low Tire Pressure Loss of Control

Prolonged driving at low tire pressure or even short-term driving at high speeds on tires which have too low a pressure is likely to result in a loss of control of your vehicle, either due to a failure to maintain directional control under side loads or due to tire failure.

Tires are inflated to comfort pressure at the factory, which is not suitable for driving at very high speeds.

Always adjust the pressure in the tires to the standard pressure setting when driving at higher speeds.
Remember to adjust the setting in the Tire Pressure Monitoring accordingly.

Comfort pressure speed warning
If the maximum speed of the preset comfort pressure is exceeded and the tire pressure is below a defined limit, a warning message appears on the multi-function display.

Excessive Speeds for Comfort Setting

Driving at excessive speeds when the comfort pressure is active will eventually destroy the tires and that can lead to a loss of control of the vehicle, especially at high speeds.

Never exceed the speed specified on the warning message.
Always set the standard tire pressure when driving at higher speeds.

Selecting tire type in the Tire pressure menu (type and size of fitted tire)

Exceeding Maximum Rated Tire Speed

Exceeding the maximum tire speed could result in a tire burst, causing loss of control of the vehicle.

Always observe the permissible maximum speed of the respective tire.
Porsche recommends obeying all traffic laws at all times to maintain the safety of yourself and all vehicle occupants.

Entering Tire Data and Display

Incomplete entries or selection of the wrong tires on the multi-function display affect correct indication of warnings and messages.

The settings must be updated in the "Tire pressure" menu after changing a wheel, filling with tire sealant or adding air (after previous warning "Tire pressure!").
Please see the chapter "RED WARNING – TIRE PRESSURE!" on page 110.

The new tire type and tire size must be selected even if the settings for the new set of wheels are the same as for the old wheels.

Option is selected.
Option is not selected.

Tire selection has only been completed successfully when the following message appears on the multi-function display (example):
"No monitoring, System is learning".

Information
Before fitting tires with dimensions that are not already stored in the multi-function display, the missing information should be added to the multi-function display by your authorized Porsche dealer.

Please contact an authorized Porsche dealer.
Use only tires approved by Porsche.

The available items in the tire pressure menu depend on the model type. For this reason, some of the selection options shown here may not be available on your multi-function display.

System learning
Tire Pressure Monitoring begins to "learn" the tires after a wheel change, wheel transmitter replacement or update of the tire settings.

During this process, Tire Pressure Monitoring recognises the wheels and their locations.

The message "No monitoring, System is learning" appears on the multi-function display.

The wheel learning process takes place exclusively when the vehicle is being driven (vehicle speed above 16 mph/25 km/h).

Tire Pressure Monitoring requires a certain amount of time to learn the wheels. During this time, the current tire pressures are not available on the multi-function display:
– The tire pressure warning light remains lit until all wheels have been learned.
– Lines (-.-) appear on the display of the "Tire pressure" function.
– The required pressures for cold tires (68 °F/ 20 °C) are indicated under "Fill info" in the "Tire pressure" main menu.

Position and pressure information is displayed as soon as Tire Pressure Monitoring has assigned the wheels recognised as belonging to the vehicle to the correct wheel positions.

Check the tire pressure for all wheels under "Fill info".
Correct the tire pressure to the required pressure if necessary.

Tire pressure warnings
The tire pressure warning light on the instrument panel and a corresponding message on the multi-function display warn about loss of pressure in two stages (yellow and red), depending on the amount of pressure loss.

Yellow warning – Top off air!
The pressure in the tire is too low by more than 4 to 7 psi/0.3 to 0.5 bar/30 to 50 kPa. The tire pressure warning specifies the affected tire and the target tire pressure.

Correct the tire pressure at the next opportunity.

This tire pressure warning appears
– the first time for approx. 10 seconds when the vehicle is
stationary and the ignition is switched off or
– when the ignition is switched on again.

The warning can be acknowledged when the ignition is switched on.

The tire pressure warning light on the instrument panel goes out only when the tire pressure has been corrected.

Red warning – Tire pressure!
At speeds below 100 mph (160 km/h):
– The pressure in the tire has dropped by more than 7 psi / 0.5 bar /
50 kPa. This significant pressure loss is a danger to road safety.

At speeds above 100 mph (160 km/h):
– The pressure in the tire has dropped by more than 6 psi / 0.4 bar /
40 kPa. This significant pressure loss is a danger to road safety.

When the tire pressure warning appears, stop immediately at a suitable location.
Check the indicated tire for signs of damage. If necessary, fill in tire sealant and set the correct tire pressure.

This tire pressure warning also appears when driving and can be acknowledged.

The tire pressure warning light on the instrument panel goes out only when the tire pressure has been corrected.

For information on tire sealing compound:

Please see the chapter "FILLING IN TIRE SEALANT" on page 237.

Warning light
The warning light in the instrument panel lights up:
– When a loss in pressure has been detected.
– In the event of a defect in Tire Pressure Monitoring or a temporary fault.
– When learning new fitted wheels/wheel transmitters, as long as the vehicle's own wheels have not yet been recognised.

A warning message also appears on the multi-function display in the instrument panel.

Please see the chapter "OVERVIEW OF WARNING AND INFORMATION MESSAGES" on page 126.

The tire pressure warning light on the instrument panel goes out only when the cause of the fault has been rectified.

Changing a wheel and replacing tires

New wheels must be fitted with radio transmitters for Tire Pressure Monitoring.
Before tires are changed, the battery charge condition of the wheel transmitters should be checked.
Please contact an authorized Porsche dealer.
Switch off the ignition when changing a wheel.

The tire settings on the multi-function display must be updated after changing a wheel.

If the tire settings are not updated, the message "Tire change? Update settings!" is displayed on the multi-function display.

Update the multi-function display settings the next time the vehicle is stationary.

Pressure increase as the result of temperature increase
In accordance with physical principles, the tire pressure changes as the temperature changes. For every 18 °F (10 °C) change in temperature, the tire pressure increases or decreases by around 1.5 psi/0.1 bar/10 kPa.

Partial monitoring
Monitoring 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 "Restricted monitoring" appears on the multi-function display.
– No tire pressures are displayed on the multi-function display for wheels with faulty wheel transmitters.

No monitoring
In the event of faults, Tire Pressure Monitoring cannot monitor the tire pressure.

The warning light on the instrument panel lights up and a corresponding message appears on the multi-function display.

Monitoring is not active:
– If Tire Pressure Monitoring is faulty.
– If wheel transmitters for 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.
– If more than four wheel transmitters are recognized.
– If there is external interference by other radio sources, e.g. wireless headphones.
– If tire temperatures are too high.

Please see the chapter "OVERVIEW OF WARNING AND INFORMATION MESSAGES" on page 126.


Chrono Menu (Stopwatch)
You can use the stopwatch to measure any times, e.g. on race circuits or on work-related journeys. Measured lap times can be stored and evaluated if the vehicle is equipped with Porsche Communication Management (PCM).
