Function and control
Fig. 253 In the stowage compartment on the front passenger side: button for the tyre monitoring sys-tem.
l"'"""f'n First read and observe the Introductory l.-J,.:,LL Information and safety warnings & on page 318.
The tyre monitoring system uses data from the ASS sensors and other functions to check the speed of rotation and the rolling circumference of the individual wheels. The rolling circumference of the wheels changes, if the tyre pressure is too low. This is then shown by the tyre monitoring sys-tem ill in the instrument cluster.
The operation of the tyre monitoring system is im-paired:
• If the tyre pressure has been changed manual-ly.
• If the tyre has structural damage.
• If the vehicle Is loaded more heavily on one side.
• If the wheels on one axle are loaded more heavily, e.g. high load level.
• If snow chains have been fitted.
• If one wheel per axle has been changed.
• When driving with a heavy trailer attached.
• If you are driving under winter conditions or on unsurfaced roads.
• When driving fast with hard acceleration and braking manoeuvres.
Synchronising the tyre monitoring system
The tyre monitoring system will have to be re-synchronised after changing the tyre pressure, or after changing one or more wheels. This also ap-plies for changing the wheels, e.g. from the front to the rear, and for changing from summer tyres to winter tyres.
The saved values must be reset before the system can be resynchronised.
• Switch on the ignition, and while the vehicle is stationary
• Press and hold the =>Fig. 253 button until an acoustic confirmation signal is emitted.
• OR: with some vehicle equipment options, you can open menu option Tyre pressure in the in-strument cluster display and save the new tyre pressures there =>page 24.
Once the saved values have been reset, the sys-tem calibrates itself independently to the fitted tyres and the tyre pressures filled by the driver dur-ing normal vehicle operation. The calibrated values are adopted and monitored after a long journey at various speeds.
If the wheels are loaded more heavily than normal, e.g. if the vehicle is carrying heavy payload, the tyre pressure must be raised to the recommended full-load tyre pressure before synchronisation =>page 367.
m The tyre monitoring system stops working if l!.J there is a fault in the ESC or ASS =>page 269.
m When using snow chains, an incorrect dis-l!.J play may be shown as the snow chains in-crease the tyre circumference =>page 367.

.....-r'n First read and observe the introductory L-W! Information and safety warnings & on page 367.
The tyres are the most used and most underesti-mated 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 pres-sure, driving style handling and fitting.
The tyres and wheel rims are an essential part of the vehicle's design. The tyres and rims approved by Volkswagen Commercial Vehicles are specially matched to the characteristics of the vehicle and make a major contribution to good road holding and safe handling.
Avoiding damage to the tyres
• If you have to drive over a kerb or similar obsta-cle, drive slowly and at a right angle if possible.
• Inspect the tyres regularly for damage such as cuts. cracks or blisters.
• Remove foreign objects that are in the outer tyre tread and have not penetrated the Inner tyre 373.
• Always respond to any warning messages giv-en by the tyre monitoring system=:opage 318.
• Damaged or worn tyres must be replaced im-mediately =:o page 373.
• Regularly check the tyres for hidden damage =:-page 373.
368 Cleaning and maintenance
• Never exceed the top speed and load permitted for the tyres that are fitted =:o page 375.
• Protect the wheels, including the spare wheel, from contact with corrosive substances, including oils, lubricants, fuel and brake fluid =:o &.
• Replace missing dust caps immediately.
Tyres with directional tread pattern
Tyres with directional tread pattern have been de-veloped to roll in one direction only. An arrow on the tyre sidewall indicates the direction of rotation on tyres with directional tread =:o page 375. The di-rection of rotation must be adhered to. This is the only guarantee for optimum grip and helps to avoid aquaplaning, excessive noise and wear.
If, however, the tyre is fitted in the opposite direc-tion to the tread pattern, you must take more care when driving as the tyre is now no longer being used according to its designation. This is particu-larly important on wet roads. The tyres must be re-placed as quickly as possible or be fitted with the tread in the correct direction.
Rotating wheels front to rear
Regularly rotating the wheels as shown in the illus-tration =:o Fig. 280 is recommended to help ensure that tyres wear evenly. All the tyres will then last for about the same time.
Volkswagen Commercial Vehicles recommends having the wheels changed by a qualified work-shop.
Tyres that are older than 6 years
Tyres age through physical and chemical process-es that can impair their function. Tyres that are stored unused for an extended period will harden and become brittle more quickly than tyres which are in constant use.
Volkswagen Commercial Vehicles recommends re-placing tyres that are more than 6 years old with new tyres. This also applies for tyres, including the spare wheel, which appear to still be in good con-dition and whose tread depth has not yet reached the minimum value stipulated by legislation =:o &.
The age of a tyre can be determined from the man-ufacturing date, which Is a component of the tyre identification number (TIN) =:o page 375. .,..
be repaired by a qualified workshop. Volkswagen Commercial Vehides recommends using a Volks-wagen Commercial Vehicles dealership for this purpose => &.
Rims with bolted-on trims
Rims may have removable trims that are attached to the rim with self-locking bolts. Damaged trims may only be repaired by a qualified workshop. Volkswagen Commercial Vehicles recommends us-ing a Volkswagen Commercial Vehicles dealership for this purpose => &.
Rim identification
In some countries, new rims are legally required to contain certain specifications on them. The follow-ing information may appear on the rims (varying from region to region):
• Seal of conformity
• Rim size
• Name of manufacturer or brand name
• Date manufactured (month/year)
• Country of origin
• Production number
New wheels and tyres
r--f'n First read and observe the introductory L-Wl information and safety warnings & on page 367.
New tyres
• Drive particularly carefully for the first 600 km with new tyres as the tyres have to be run in. Tyres that have not been run in have reduced grip=>& and braking effect => &.
• All four wheels must be fitted with radial tyres of the same type, size (rolling circumference) and the same tread.
• The tread depth of new tyres may vary, accord-ing to the type and make of tyre and the tread pat-tern.
370 I Clcanmg and maintenance
• Raw materials batch number
• Product code
A WARNING
The use of unsuitable or damaged rims can impair vehicle safety and cause accidents and serious injury.
• Only use rims that have been approved for the vehicle.
• Check the rims regularly for damage and replace as necessary.
A WARNING
Incorrect loosening and tightening of the bolts on rims with bolted-on rings can cause accidents and serious Injury.
• Never remove the bolts on rims with bot-ted-on rings.
• All work on rims with bolted-on rings must be carried out by a qualified workshop. Volks-wagen Commercial Vehicles recommends us-ing a Volkswagen Commercial Vehicles deal-ership for this purpose.
Replacing tyres
• Tyres should be replaced at least in pairs and not individually (i.e. both front tyres or both rear tyres together) => &.
• Old tyres should only be replaced by tyres that have been approved by Volkswagen Commercial Vehicles for the vehicle type. Make sure that the tyres used are correct in respect of size, diameter. load-carrying capacity and maximum speed.
• Never use tyres with an effective size that is larger than tyres approved by Volkswagen Com-mercial Vehicles. Larger wheels could rub against the body or other parts of the vehide.
Additional information for vehicles with tyre monitoring system
For vehides with a tyre monitoring system, the sys-tem will have to be "re-synchronised" after any wheel changes, regardless of whether the wheel in question is being fitted in the same or in a different position =>page 318.
Further information about the tyre monitoring sys-tem, how it functions and what you must know
A WARNING (Continued)
• Worn tyres reduce the possibility of con-trolling the vehicle well in normal and difficult driving situations and Increase braking dis-tance and the risk of sliding.
...--m First read and observe the introductory l-.W.I Information and safety warnings&,. on page 367.
Damage to tyres and rims is often not readily visi-ble. Any unusual vibrations or signs that the car is pulling to one side may indicate that one of the tyres is damaged =:. &,..
• Reduce your speed immediately if you suspect that a wheel is damaged.
• Check the tyres and rims for damage.
• If the tyre is damaged, do not drive on. Seek expert assistance.
• If there is no visible damage, drive slowly and cautiously to the next qualified workshop in order to have the vehicle checked.
Foreign bodies in the tyre
• Leave the foreign body in the tyre if it has en-tered the inner tyre. However, foreign bodies that are stuck between the tyre tread blocks can be re-moved.
• For vehicles with a spare wheel: where appro-priate, change the damaged wheel =:>page 420 If required, seek expert assistance when changing the damaged wheel. Volkswagen Commercial Ve-hicles recommends using a Volkswagen Commer-cial Vehicles dealership for this purpose.
• For vehicles with a breakdown set: the tyre can be sealed and pumped up using the tools in the breakdown set =:.page 425. Go to a qualified workshop. Volkswagen Commercial Vehicles rec-ommends using a Volkswagen Commercial Vehi-cles dealership for this purpose.
Tyre wear
The tyre wear is affected by several factors, for ex-ample:
• Driving style.
• Unbalanced wheels.
• Running gear setting.
Driving style-fast cornering, heavy acceleration and hard braking all increase tyre wear. The run-ning gear should be checked by a qualified work-shop if the tyres show excessive wear despite a normal driving style.
Unbalanced wheels -the wheels on new vehicles are balanced. However, various factors encoun-tered in normal driving can cause them to become unbalanced, which results in steering vibration. Un-balanced wheels will affect levels of wear on the steering system and the suspension. In this case the wheels should be balanced again. New tyres have to be balanced after fitting.
Running gear setting-incorrect wheel alignment causes excessive tyre wear, impairing the safety of the vehicle. The wheel alignment should be checked by a qualified workshop if tyres show ex-cessive wear.
A WARNING
If you notice unusual vibration or the car pull-Ing to one side while the vehicle is In motion, this may indicate that one of the tyres is dam-aged.
• Reduce speed immediately and park the vehicle without obstructing traffic.
• Check the tyres and rims for damage.
• Never drive on if wheels or tyres are dam-aged. Seek expert assistance Instead.
• If there Is no visible damage, drive slowly and cautiously to the next qualified workshop In order to have the vehicle checked.

Winter tyres
r-f'n First read and observe the introductory L-J,::JJ information and safety warnings & on page 367.
In winter road conditions, winter tyres will consider-ably improve the car's handling. The design of summer tyres (width, rubber compound, tread pat-tern) gives less grip on ice and snow. Volkswagen Commercial Vehicles urgently recommends you use winter tyres or all-year tyres on all 4 wheels of the vehicle, particularly if winter conditions are ex-pected on the roads. Winter tyres will also improve the braking response of the vehicle and will help to reduce braking distances in winter weather. Volks-wagen Commercial Vehicles recommends that win-ter tyres be fitted to the vehicle at temperatures un-der+ 7•c (+45°F).
Winter tyres lose their effectiveness when the tread is worn down to a depth of 4 mm. Winter tyres also largely lose their effectiveness through ageing-regardless of the tread depth.
The following applies when using winter tyres:
• Observe any country-specific legal require-ments.
• Use winter tyres on all four wheels at the same time.
• Only use in winter road conditions.
• Only use the sizes of winter tyre that have been approved for the vehicle.
• Winter tyres must have the same type, size (rolling circumference) and the same tread pattern.
• Heed the maximum speed permitted by the speed index => &.
Speed limitation
Winter tyres have a speed limitation depending on the speed index =>page 375.
In some vehicle versions, a speed warning can be set in the menu MFD (multi function display) in the instrument cluster =>page 24.
378 I Cleaning and maintenance
Some tyre manufacturers use the code "ZR" for tyres with a highest permitted speed of over 240 km/h (149 mph).
If you use V-rated tyres the speed limits and re-quired tyre pressure will be determined by the en-gine size. You must ask a Volkswagen Commercial Vehicles dealership about the highest permitted speed and required tyre pressure.
Four-wheel drive (4MOTION)
Thanks to its four-wheel drive, the vehicle will have plenty of traction in winter conditions, even with the standard tyres. Nevertheless, Volkswagen Com-mercial Vehicles still recommends that winter tyres or all-year tyres should be fitted on all four wheels when winter road conditions are expected, mainly because this will give a better braking response.
Please refer to the appropriate information and notes when using snow chains =>page 379.
A WARNING
The Improved winter driving characteristics afforded by the winter tyres should not en-courage you to take any risks.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con-ditions.
• Never exceed the top speed and load per-mitted for the winter tyres that are fitted.
r:Q;-.. Summer tyres should be fitted in good time at the end of the winter. The vehicle handling is better if summer tyres are fitted at temperatures above +7•c (+45.F). They are quieter, do not wear so quickly and reduce fuel consumption.
