Get Wheels and tyres -> Tyre monitoring systems Guide for Volkswagen California Van Third Generation (2015-2024)

Introduction

The tyre monitoring system warns the driver when the tyre pressures get too low.

The following tyre monitoring systems are available for this vehicle:

Tyre Pressure Loss Indicator

—Various parameters (for example, rolling circumference) of all four wheels are monitored when driving using ABS

sensors (indirect measurement).

Tyre Pressure Monitoring System

—Monitors the tyre pressure by means of pressure sensors on each tyre valve(direct measurement). Tyre valves

made of metal.

Reference pressure

The reference pressure for the tyre monitoring system is the tyre pressure of cold tyres with maximum load for the

factory-fitted tyres. The reference pressure corresponds to the information on the tyre pressure sticker (→ Tyre

pressure).

If the tyre pressure of all four tyres has been adjusted correctly, the Tyre Pressure Loss Indicator must be re-

synchronised (→ Tyre Pressure Loss Indicator). The reference pressure is then adapted to the current tyre pressure.

WARNING

The intelligent tyre monitoring system technology cannot overcome the laws of physics, and functions only within

the limits of the system. Incorrect handling of the wheels and tyres can lead to a sudden loss of pressure in the

tyres, tread separation and even tyre blow-out.

● Check the tyre pressure regularly and always maintain the specified pressure (→ Tyre pressure). If the tyre

pressure is too low, it is possible that the tyre temperature will increase to such an extent that the tread peels off

and the tyre bursts.

● Always maintain the correct cold tyre pressure as specified on the tyre pressure sticker (→ Tyre pressure).

● Check the tyre pressure regularly when the tyres are cold. If necessary, adjust the tyre pressure in the cold tyre to

the recommended tyre pressure for the tyres installed on your vehicle (→ Tyre pressure).

● Check your tyres regularly for signs of wear or damage.

● Never exceed the top speed and load permitted for the fitted tyres.

If the tyre pressure is too low, this will increase fuel consumption and tyre

wear.

When new tyres are driven at high speeds for the first time, they can expand slightly and trigger a one-off

pressure warning.

Old tyres should be replaced only by tyres that have been approved by Volkswagen Commercial Vehicles for

the vehicle type.

Do not rely only on the tyre monitoring system alone. Check your tyres regularly to ensure that they are

properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove any

objects that become embedded in the tyre tread but have not penetrated into the body of the tyre itself.

Tyre Pressure Loss Indicator

Functional description

The Tyre Pressure Loss Indicator uses data from the ABS sensors and other functions to check the speed of rotation

and the rolling circumference of the individual wheels.

The Tyre Pressure Loss Indicator does not work if there is a fault in the

ESC

or ABS (→ Brake support systems).

The rolling circumference may change:

—If the tyre pressure has been changed.

—If the tyre pressure is too low.

—If the tyre has structural damage.

—If the vehicle is loaded more heavily on one side.

—If snow chains have been fitted.

—If a temporary spare wheel has been fitted.

—If one wheel per axle has been changed.

The Tyre Pressure Loss Indicator may react with a delay or not display anything at all in the event of a sporty driving

style, when driving on snow-covered or icy roads or unpaved roads or when driving with snow chains.

The Tyre Pressure Loss Indicator shows a change in rolling circumference of the tyres with the warning lamp in the

instrument cluster.

The recommended tyre pressure for the factory-fitted tyres is indicated on the tyre pressure sticker on the driver's

door pillar (→ Tyre pressure).

The tyre pressure of all tyres, including the spare wheel or temporary spare wheel, must checked once every month

with cold tyres and must correspond to the specifications of the vehicle manufacturer on the tyre pressure sticker. If

the tyre size of the fitted tyres differs from the specified value on the type plate or tyre pressure sticker, the correct

tyre pressure must be determined.

The Tyre Pressure Loss Indicator does not replace regular maintenance and inspection of the tyres. The driver is

responsible for ensuring that the correct tyre pressure is maintained at all times, even if the Tyre Pressure Loss

Indicator does not yet display a warning about low tyre pressure.

The Tyre Pressure Loss Indicator also has a fault display which is linked to the warning lamp. If the Tyre Pressure

Loss Indicator is malfunctioning, the warning lamp flashes for about a minute after the ignition was switched on

and then stays continuously lit.

If the Tyre Pressure Loss Indicator indicates a fault, the tyre pressure cannot be monitored correctly. A malfunction of

the Tyre Pressure Loss Indicator can have various causes, e.g. due to replacement of a wheel or tyre. When a wheel or

tyre has been replaced, check whether the warning lamp is indicating a system malfunction to ensure that the Tyre

Pressure Loss Indicator is functioning properly (→ Tyre Pressure Loss Indicator).

Synchronising the Tyre Pressure Loss Indicator

The Tyre Pressure Loss Indicator must be re-synchronised under the following conditions:

—If the tyre pressures have been adapted.

—If one or more wheels have been replaced.

—If the wheels have been swapped round, e.g. from front to rear.

The Tyre Pressure Loss Indicator may be re-synchronised only if all tyres have the correct tyre pressure when

540

measured with cold tyres. To measure the cold tyre pressure, the vehicle must have been stationary for 3 hours or

driven only a few kilometres at a slow speed during this time.

Switch the ignition off and back on again if you receive a low tyre pressure warning. The Tyre Pressure Loss

Indicator can only then be re-synchronised.

1. Switch on the ignition.

2. Depending on the Infotainment system version, press the button or the

3. Open the Vehicle menu.

function button.

4. Depending on the Infotainment system version, tap Settings if necessary.

5. Tap Tyres.

6. Tap SET.

7. Tap Confirm when all four tyre pressures correspond to the required values.

The system automatically synchronises and monitors the new values after at least 20 minutes of driving time at

different speeds.

Or: Touch Cancel to terminate the process.

The current tyre pressure is then not stored and the system is not re-calibrated.

WARNING

Incorrect calibration can cause the Tyre Pressure Loss Indicator to issue false warnings or to issue no warning

despite a dangerously low tyre pressure. Make certain the tyre pressure of all tyres is correct before using the

setting button.

● Check that the tyre pressure of all tyres is correct before calibrating the Tyre Pressure Loss Indicator.

Tyre Pressure Monitoring System

Functional description

The Tyre Pressure Monitoring System (TPM

) monitors the tyre pressure of the four wheels while the vehicle is in motion using tyre pressure sensors on the tyres.

The system warns the driver in the event of a pressure loss.

6. Tap or until the Tyre Pressure Monitoring Systemscreen is displayed.

The vehicle is displayed with the target and actual tyre pressures of all the wheels→ Fig. 1.

When the ignition is switched on, the last measured tyre pressures will be displayed first; these values will be

updated when the journey is started. If the tyre pressure is too low, the respective actual values and the affected

tyres will be marked → Fig. 1.

If the tyres are in rest state, the tyre pressure sensors will not transmit any tyre pressures. This stops the tyre

pressure sensor batteries discharging.

The last received tyre pressures are shown in grey if no tyre pressures are transmitted.

Switching the Tyre Pressure Monitoring System on and off (vehicle-dependent)

Observe any country-specific legal requirements for the Tyre Pressure Monitoring System.

If a set of tyres is fitted to the vehicle where the tyres either do not have wheel sensors or have wheel sensors that

are not compatible with the vehicle, the indicator lamp will flash for approximately 1 minute and then light up

steadily. The tyre pressures will not be monitored. The system cannot be switched off.

Adjusting the tyre pressure

Following any change in the vehicle load, the tyre pressure must be checked and adjusted as necessary. The tyre

pressures recommended for the vehicle are on a sticker on the driver door pillar or on the inside of the tank flap

(→ Tyre pressure).

There may be differences between readings on the pressure gauge when filling the tyres and the values determined

by the Tyre Pressure Monitoring System. The TPM

is more precise.

Selecting target tyre pressures for partial and full loads

The driver must select the appropriate target tyre pressure depending on the vehicle load level:

1. Switch on the ignition.

2. Depending on the version, press the button or function button

.

3. Tap Vehicle .

4. Tap Settings.

5. Select Tyres.

6. Select Load.

542

7. Select the load level.

Selecting tyre type

If the tyre size is changed, it may be necessary to adjust the target tyre pressure for the new tyres. If no adjustment is

necessary, the selection menu will not be available.

1. Switch on the ignition.

2. Depending on the version, press the button or function button

3. Tap Vehicle .

.

4. Tap Settings.

5. Select Tyres.

6. Select the appropriate tyre size.

If the size of the fitted tyres does not correspond to the factory-specified tyres, the corresponding target tyre

pressure can be entered by a suitably qualified workshop.

Spare wheel, temporary spare wheel or collapsible spare wheel

The system does not monitor the tyre pressure of the spare wheel, temporary spare wheel or collapsible spare wheel.

NOTICE

● The pressure sensors are secured to special aluminium valves that are screwed rigidly in place. When inflating the

tyres and checking the pressure, do not bend the valves “into position”.

● Missing valve caps could lead to damage to the valve and the sensors. You should therefore always make sure that

all valve caps are fully screwed on while driving. Do not use metallic valve caps.

● Do not use “convenience valve caps” as they do not form a proper seal. This can cause damage to the sensors.

Troubleshooting for Tyre Pressure Loss Indicator

Low tyre pressure

The indicator lamp lights up yellow.

There is a loss of pressure in one or more tyres or the tyre is structurally damaged.

1.

Do not drive on!

2. Check and adjust all tyre pressures (→ Tyre pressure).

3. The damaged tyre should be replaced.

4. Re-synchronise the Tyre Pressure Loss Indicator (→ Tyre Pressure Loss Indicator).

5. If the fault persists, go to a correspondingly qualified workshop.

Fault in the Tyre Pressure Loss Indicator

The indicator lamp flashes for around 1 minute and then remains lit up yellow continuously.

There is a system fault.

1.

Do not drive on!

2. Switch the ignition off and then back on again.

3. Re-synchronise the Tyre Pressure Loss Indicator (→ Tyre Pressure Loss Indicator).

543

4. If the fault persists, go to a correspondingly qualified workshop.

WARNING

Differing tyre pressures or tyre pressures that are too low can cause tyre damage, tyre failure, loss of vehicle

control, accidents, serious injury and death.

● If the indicator lamp lights up, stop immediately and check all tyres (→ Tyre pressure).

● Different tyre pressures or tyre pressures that are too low can increase wear on the tyres, reduce vehicle stability

and increase the braking distance.

● Differing tyre pressures or tyre pressures that are too low can cause sudden tyre failure and lead to a tyre

bursting and the loss of control over the vehicle.

● The driver is responsible for the correct tyre pressure of all tyres on the vehicle. The recommended tyre pressure

can be found on a sticker (→ Tyre pressure).

● The tyre monitoring system cannot function correctly until all cold tyres have the correct tyre pressure.

● The pressure in all tyres must always be appropriate to the vehicle load (→ Tyre pressure).

● Always inflate all tyres to the correct tyre pressure before every journey (→ Tyre pressure).

● If the vehicle is driven with insufficient tyre pressure, this results in greater tyre flexing. This could warm up the

tyre to such an extent that the tread may separate and the tyre could burst. This could cause the driver to lose

control of the vehicle.

● High speeds and overloading of the vehicle may cause the tyres to heat up to such an extent that the tyre bursts,

leading you to lose control of the vehicle.

● If the tyre pressure is too low or too high, the tyres will wear prematurely and the vehicle will not handle well.

● If the tyre is not flat and it is not necessary to change the wheel immediately, drive at low speed to the nearest

correspondingly qualified workshop and have the tyre pressure checked and corrected (→ Tyre pressure).

● The Tyre Pressure Loss Indicator must always be calibrated correctly.

Driving on unpaved roads for long periods, or a sporty driving style, can temporarily deactivate the Tyre

Pressure Loss Indicator. In the event of a malfunction, the indicator lamp will flash for around 1 minute and

then light up continuously. However, the indicator lamp will go out when the road conditions or driving style

change.

Troubleshooting for Tyre Pressure Monitoring System

Introduction

The tyres are the most used and most underestimated parts of a vehicle. Tyres are very important as the narrow tyre

surfaces are the only contact between the vehicle and the road.

The service life of tyres is dependent on tyre pressure, driving style, handling and correct fitting.

Volkswagen Commercial Vehicles recommends that all work on tyres and wheels is carried out by a suitably qualified

workshop. They are familiar with the procedure and have the necessary special tools and spare parts and the proper

facilities for disposing of the old tyres.
