SCR catalysts can be used to reduce emissions from diesel engines (SCR = Selective Catalytic Re-duction). The SCR catalyst uses Ad Blue® urea sol-ution to convert nitrogen oxides into nitrogen and water.
If the vehicle is equipped with this kind of emission control system for diesel vehicles, the filler neck for the Ad Blue® tank is located below the filler cap for the fuel tank.
The Ad Blue® level should be checked within the scope of the service work Service schedule.
Information on AdBiue®
The Ad Blue® consumption figures depend on the individual driving style, the system's operating tem-perature and the ambient temperature that the ve-hicle is operated in.
The vehicle is fitted with a separate tank for Ad Bl-ue®. The Ad Blue® tank holds approximately 13 li-tres. For technical reasons, the capacity may be slightly larger when refilling using refill bottles.
The Ad Blue® tank must never run empty. As of a remaining distance of approximately 2,400 km. the instrument cluster display will indicate that the
346 While drivmg
Ad Blue® must be refilled 348. If the re-maining range is 0 km, the engine cannot be star-ted anymore 347.
The Ad Blue® trademark is held by the German As-sociation of the Automobile Industry (VDA) in the USA, Germany, the European Union and other countries.

A WARNING (Continued)
• Engine oil is toxic and must be stored out of the reach of children.
r:Q:.. Before changing the engine oil, first find out W where old oil can be disposed of properly near you.
Used oil must be disposed of in accordance W with regulations governing the protection of the environment. Never dispose of old oil in loca-tions such as gardens, woods, sewerage systems, on streets and roads, or in rivers and waterways. A WARNING
Engine coolant is poisonous and can cause serious Injuries.
• Engine coolant should only be kept in sealed original containers In a safe place.
• Never store engine coolant In empty food containers, bottles or any other non-original containers as people finding these containers may then drink the engine coolant.
• The engine coolant must be stored out of the reach of children.
• Please note that the amount of correct coolant additive used must be sufficient for the lowest ambient temperature that you ex-pect the vehicle to be exposed to.
• Coolant can freeze at extremely cold out-side temperatures, causing the vehicle to break down. Vehicle occupants with Inade-quate winter clothing could then freeze to death as the heating will also no longer func-tion.
Coolant and coolant additives can pollute the W environment. Spilt service fluids must be col-lected then disposed of properly and in an environ-mentally responsible way.

Coolant specification
r-l"'n First read and observe the Introductory l..-J,::,U Information and safety warnings & on page 358.
The cooling system is filled at the factory with a mixture of specially prepared water and at least 40% coolant additive G 13 (fl-VW 774 J). The coolant additive is dyed purple. This mixture of wa-ter and coolant additive gives the necessary frost protection down to -2s•c (-13.F) and protects the alloy parts of the cooling system against corrosion. The mixture also prevents scaling and raises the boiling point of the coolant.
In order to protect the coolant system, the propor-tion of coolant additive must always be at least 40%, even if anti-freeze is not required in warm weather and warm climates.
If greater frost protection is required in very cold climates, the proportion of anti-freeze additive can be increased. However, the percentage of coolant additive should not exceed 60%, as this would re-duce the frost protection and the cooling effect.
When refilling the coolant, a mixture of distilled water and at least 40% coolant additive G 13 or G 12 plus-plus (TL-VW 774 G) (both of which are dyed purple) must be used in order to obtain the optimum corrosion protection =>(]). Mixing G 13 with the coolant additives G 12 plus (Tl-VW774 F), G 12 (dyed red) orG 11 (dyed blue-green) will significantly decrease the level of corro-sion protection and should therefore be avoided => A WARNING
Insufficient anti-freeze In the coolant system can cause the engine to break down and cause serious Injuries.
• Please note that the amount of correct coolant additive used must be sufficient for the lowest ambient temperature that you ex-pect the vehicle to be exposed to.
• Coolant can freeze at extremely cold out-side temperatures, causing the vehicle to break down. Vehicle occupants with Inade-quate winter clothing could then freeze to death as the heating will also no longer func-tion.
360 I Cleaning and maintenance
CD
Never mix genuine coolant additives with other coolants that have not been approved by Volks-wagen. Mixing other coolants could cause seri-ous damage to the engine and cooling system.
• If the liquid in the coolant expansion tank is brown instead of purple, for example, G 13 has been mixed with another unsuitable engine coolant. The coolant must be changed as soon as possible if this Is the case. Failure to ob-serve this point can result In serious faults or engine damage.
Coolant and coolant additives can pollute the "7!1:5 environment. Spilt service fluids must be col-lected then disposed of properly and in an environ-mentally responsible way.

A wARNING
New tyres will have to be run in as they will Initially have reduced grip and braking effect.
• Drive particularly carefully for the first 600 km in order to prevent accidents and se-rious injury.
A WARNING
Wheels must have the necessary freedom of operation. If the wheels do not have the nec-essary freedom of operation, the tyre could rub on parts of the running gear, the vehicle body and the brake lines. This can lead to a fault in the brake system and to tread separa-tion and thus to a tyre bursting.
Tyre pressure
r-T'n First read and observe the introductory L-k.U Information and safety warnings & on page 367.
The correct tyre pressure for factory-fitted tyres is shown on the tyre pressure label and applies to all-season, summer and winter tyres. The tyre pres-sure label is located on the lock column on the left front door.
If the tyre pressure is too low or too high, the tyres will wear prematurely and the vehicle will not han-dle well => &. The correct tyre pressure is particu-larly important at high speeds. Incorrect tyre pres-sure causes premature wear and can cause a tyre burst.
The pressure should therefore be checked at least once a month and before starting a journey.
The given tyre pressure applies to cold tyres. Tyre pressure is always higher in warm tyres than it is in cold tyres.
For this reason, never reduce the pressure in warm tyres to adjust the tyre pressure. This would result in low tyre pressures that could potentially cause the tyre to burst suddenly.
Checking tyre pressure
Always check the tyre inflation pressure on "cold" tyres. A "cold" tyre can be defined as one on a ve-hicle that has only been driven a few kilometres (miles) within 3 hours prior to the test and at low speeds.
A WARNING (Continued)
• The actual tyre size must not exceed the tyre dimensions of manufacturers approved by Volkswagen Commercial Vehicles and must not rub on any vehicle body parts.
m Despite identical size details, the actual size L!..J of the various tyre makes may vary from these specified dimensions, or the tyre contours may vary considerably.
m Volkswagen Commercial Vehicles-approved L!..J tyres are guaranteed to have the dimensions that are suitable for the vehicle. The salesperson will have to provide a certificate from the tyre man-ufacturer for other tyre makes to prove that the tyre is also suitable for the vehicle. This certificate must be stored in a safe place in the vehicle. • The tyre pressures should be checked regularly and only when the tyres are cold. Always check all the tyres. including the spare if fitted. The tyre pressure should be checked more frequently in colder regions, but only if the vehicle has not been moved beforehand. The tyre pressure tester must function correctly.
• The tyre pressures must be adjusted to suit a heavy vehicle load.
• After altering the tyre pressures, please ensure that the valve caps are screwed on and observe any information and instructions on setting the tyre monitoring system =>page 318.
The temporary spare wheel is filled to the highest tyre pressure permissible for the vehicle.
A WARNING
Too high or too low a pressure may cause the tyre to suddenly lose pressure or burst while the vehicle is in motion. This can cause seri-ous accidents and fatal Injuries.
• If the tyre pressure Is too low, it is possi-ble that the tyre temperature will increase to such an extent when driving that the tread peels off and the tyre bursts.
• Fast speeds or overloading of the vehicle can cause overheating, sudden tyre damage including tyre bursts and ripping of the tread surface and thus to a loss of control of the vehicle.
• If the tyre pressure is too low or too high, the tyres will wear prematurely and the vehi-cle will not handle well. .,.

Removing wax
Car washes and care products could leave wax deposits on the glass surfaces. Wax residue can only be removed using a special cleaning product or cleaning cloths. Wax deposits on the wind-screen can cause the wiper blades to rub. Volks-wagen Commercial Vehicles recommends that a glass cleaning cloth G 052 522 A1 be used to re-move wax deposits from the windows and exterior mirrors each time the vehicle is washed.
A window cleaning agent specifically for removing wax will stop the blades rubbing if added to the windscreen wash water. Dilute the cleaner as in-structed. Grease-removing cleaners will not re-move wax deposits =-CD.
Special cleaners, glass cleaners and glass clean-ing cloths are available from Volkswagen Commer-cial Vehicles dealerships.
Removing snow
Use a small brush to remove snow from the win-dows and exterior mirrors.
Removing ice
The best method for removing ice is to use a de-icer spray. If you use an ice scraper, do not move it to and fro, but push it in one direction only. Mov-ing the ice scraper backwards can cause dirt to scratch the window.
