service VOLKSWAGEN EOS 2008 Owner's Guide

WARNING
x An improperly installed or incorrect trailer hitch can cause a trailer to separate from the tow vehicle and cause serious personal injuries.
x If you don't have to tow a trailer any more, remove the entire trailer hitch. Always seal all bolt holes to prevent water and deadly exhaust fumes from getting into the vehicle.
NOTICE
x If the trailer lights are not connected properly, the vehicle's electronics may be damaged.
x If the trailer uses too much electricity, the vehicle's electronics may be damaged.
x Never connect the electrical system for the trailer directly to the electrical connections for the rear lights or to any other unsuitable power sources. Use only a suitable connector to provide power to the trailer.
If you tow a trailer frequently, Volkswagen recommends having the vehicle serviced between the regular maintenance and inspection intervals because of the extra load it has to pull.
Hitching up and connecting a trailer

WARNING
New tires or tires that are old, worn or damaged cannot provide maximum control and braking performance.
x Improper care and handling of tires and wheels can reduce driving safety and cause accidents and severe injuries.
x Install only radial tires of the same make, the same dimensions (tread circumference), and similar tread profile on all 4 wheels.
x New tires tend to be slippery and must be broken in. Always drive with special care for the first 350 miles (560 km) to help reduce the risk of losing control, a collision, and serious personal injuries.
x Check tire inflation pressure regularly when the tires are cold and always maintain the prescribed tire pressure. Low tire pressure can cause tires to get too hot, resulting in tread separation, sudden loss of pressure, and blowouts. Tires with excessively low pressure flex (bend) more, which can cause the tire to overheat and fail suddenly without warning.
x Check tires regularly for wear and damage.
x Never drive with worn or damaged tires (for example, tires with punctures, cuts, cracks, blisters, or bumps). Driving with worn or damaged tires can lead to loss of vehicle control, sudden tire failure including blowouts and sudden deflation, crashes, and serious personal injuries.
x Have worn or damaged tires replaced immediately.
x Never exceed the maximum speed rating or the maximum load rating of the tires on your vehicle.
x The effectiveness of the driver assistance systems and the braking support systems depends on the tire traction.
x If you notice unusual vibration or if the vehicle pulls to one side when driving, always stop as soon as it is safe to do so and check the wheels and tires for damage.
x To reduce the risk of losing control, crashes, and serious personal injuries, never loosen the bolts on wheels with bolted rim rings.
x Never mount used tires on your vehicle if you are not sure of their past use. Old, used tires and wheels may have damage that cannot be seen that can lead to sudden tire failure and loss of vehicle control.
x Tires age even if they are not being used and can fail suddenly, especially at high speeds, causing loss of vehicle control, accidents, and severe personal injuries. Tires that are more than 6 years old can be used only in an emergency and even then only with special care and at low speed.
For technical reasons it is usually not possible to use wheel rims from other vehicles. Even wheel rims from the same model may not fit properly. Check with an authorized Volkswagen dealer or authorized Volkswagen Service Facility if necessary.

If you have to mount a tire opposite to its proper direction of rotation, you must drive more carefully, since the tire is no longer being used as designed. This is particularly important on wet roads. You must replace or remount the tire as soon as possible in order to restore the correct direction of rotation.
Rotating tires
To help ensure even wear on all tires, regular tire rotation according to the diagram ⇒ fig. 103 is recommended. In this way all tires can have about the same service life.
Volkswagen recommends that you have your tires rotated by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Tires more than 6 years old
Tires age even if they are not being used. Physical and chemical processes reduce tire strength and performance and cause them to harden and become brittle. Old tires can fail suddenly and without warning.
Volkswagen recommends replacing tires that are 6 years and older. This also applies to tires that look new (including the tire on the compact spare wheel) or that seem to still be usable with tread depth
that has not yet reached the legal minimum depth ⇒ .
The age of each tire can be determined with the manufacturing date that is part of the U.S. DOT tire identification number (TI N), Tire labeling.
Tire storage
Mark tires before removing them to help make sure that the previous location (left, right, front, rear) and rolling direction can be maintained when remounting them. Store tires in a cool, dry and preferably dark place. Do not store tires mounted on wheels standing up.
Tires not mounted on wheels should be covered to help protect them from dirt and stored vertically (sitting on the tread).
WARNING
Aggressive fluids and materials can cause visible and invisible tire damage that can cause tire blowouts.
x Always keep chemicals, oils, grease, fuels, braking fluids and other aggressive substances away from tires.
WARNING
Tires age even if they are not being used and can fail suddenly, especially at high speeds, causing loss of vehicle control, accidents, and severe personal injuries.
x Tires that are more than 6 years old can be used only in an emergency and even then only with special care and at low speed.
Always dispose of old tires in accordance with legal requirements.
Wheel rims

The design of the wheel bolts is matched to the factory-installed wheels. If different wheels are installed, wheel bolts with the right length and bolt head shape must be used. This helps to ensure that wheels can be mounted securely and that the brakes will work correctly, Changing a wheel.
In most cases, you cannot use wheel bolts from a different vehicle. Even wheel rims from the same model may not fit properly.
Tires and wheel rims approved by Volkswagen have been matched precisely to your vehicle model and contribute considerably to good handling and safe vehicle performance.
Tightening torque
Wheel bolts must always be installed with the correct tightening torque ⇒ page 442. The required tightening torque for your vehicle's wheel bolts is 88 ft-lbs (120 Nm). After changing a wheel, the bolt torque must be checked as soon as possible with an accurate torque wrench. See an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Wheel rims with bolted rim rings
Wheel rims with bolted rim rings have several parts. The parts are bolted together with special screws in a special process. This helps to ensure that they will work properly, prevent leaks, run true and safely. Damaged wheel rims must be replaced, and you must never take them apart or try to repair them yourself. Have an authorized Volkswagen dealer or an authorized Volkswagen Service Facility
repair them for you ⇒ .
Wheel rims with bolted decorative covers
Light-alloy wheels may have interchangeable decorative covers attached to the rim with self-locking screws. If you want to replace damaged wheel covers, contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
WARNING
Using improper or damaged wheel rims can affect driving safety, cause accidents and severe personal injury.
x Use only wheel rims approved for the vehicle.
x Regularly check wheel rims for damage and replace them if necessary.
WARNING
Improper loosening and tightening of the bolts on wheel rims with bolted rim rings can cause accidents and severe personal injury.
x Never loosen bolted connections on wheel rims with bolted rim rings.
x Have all work on wheel rims with bolted rim rings performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
New and replacement tires

x Install only radial tires of the same make, the same dimensions (tread circumference), and similar tread profile on all 4 wheels.
x The tread depth of new tires can differ between tire models and manufacturers because of different design features and tread design.
Replacing tires
x Tires should be replaced in pairs and not individually (both front tires or both rear tires at the same
time) ⇒ .
x Replace tires only with tires that have the same specifications, including width and diameter, load and top speed rating as the tires approved by Volkswagen for your vehicle and model.
x Never use tires that are larger or wider than the dimensions of the tires approved by Volkswagen for your vehicle and model. Larger tires could scrape and rub on the vehicle body or other parts of the vehicle.
Tire Pressure Monitoring System (TPMS) considerations
Factory-installed wheels are equipped with a sensor that constantly monitors tire pressure, then transmits this information to the TPMS, Tire Pressure Monitoring System (TPMS). If you are going to replace the wheels, make sure that the new wheels also have sensors that are compatible with the TPMS on your vehicle. New wheels with sensors have to be recognized and integrated into the system. To detect the new wheels and sensors, you must leave the vehicle parked for at least 20 minutes and then drive for a short time at speeds above 15 mph (25 km/h).
If you install wheels that do not have sensors, or have sensors that are not compatible, the TPMS will not work properly. In this case, the TPMS will not be able to monitor tire pressure or warn you if pressure is low. An error message may appear in the instrument cluster display or the TPMS will switch itself off.
x Whenever you change sensors, you have to install new valves and seals. Please see an authorized Volkswagen dealer of an authorized Volkswagen Service Facility.
x Always drive with the valve caps securely installed. We recommend using factory-supplied valve caps. Ask an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to replace lost caps.
If you install new tires that differ from the original Volkswagen specifications for your vehicle and model, the benchmark tire inflation pressure values stored in your vehicle's TPMS may have to be adjusted (reprogrammed). This requires professional assistance. For more information, contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Installing replacement tires with steel cord body plies in the tire sidewall may cause a TPMS malfunction and is not recommended (cord material information is molded on the tire sidewall).
Always check the TPMS indicator light after replacing one or more tires on your vehicle. If the indicator light is on, the TPMS is not working properly. Your replacement tire might be incompatible with the system or some component of the TPMS may be damaged.
For detailed information about the TPMS, how it works, and what you need to know, Tire Pressure Monitoring System (TPMS).
WARNING
New tires tend to be slippery and must be broken in.
x Always drive with special care for the first 350 miles (560 km) to help reduce the risk of losing control, a collision, and serious personal injuries.

WARNING
Tires must have the required clearance. Tires that do not have enough clearance can rub against parts of the vehicle body, suspension, and brake system, causing brake system failure, tread delamination, and sudden blowouts.
x Always make sure that new tires are not larger than the tires approved for your vehicle and that the new tires do not rub against parts of the vehicle.
NOTICE
x When switching to different tires, make certain the valves and sensors are not damaged.
x Never drive without valve stem caps. The valves and sensors of the Tire Pressure Monitoring System could be damaged.
x If the sensor on the Tire Pressure Monitoring System must be replaced, the valve must be replaced at the same time.
Always dispose of old tires in accordance with legal requirements.
TPMS wheel sensors are classified as Perchlorate Material – Special handling may apply. Obey all legal requirements regarding handling and disposal of these components – see http://www.dtsc.ca.gov/hazardouswaste/perchlorate. Obey all applicable legal requirements regarding handling and disposal of the vehicle or parts of its restraint system, including airbag modules and safety belts with pretensioners. Authorized Volkswagen dealers and authorized Volkswagen Service Facilities are familiar with the requirements, and we recommend that you have them perform this service for you.
If the replacement wheel is different from the tires that you have mounted on your vehicle (for example: winter tires; wider, low-profile tires; or a compact spare), then use the replacement wheel for a short time only, and drive cautiously.
x Replace it with a tire matching the others on your vehicle as soon as possible.
Although tire size specifications can be the same, the actual dimensions may differ from those nominal values for different tire makes, or the tire contours may be significantly different.
Tire inflation pressure

Fig. 104 On the driver door jamb: Location of the tire inflation pressure label.

Wheel rim and tire damage is often difficult to see. Unusual vibrations or pulling to one-side can be
an indication of tire damage ⇒ .
x If you suspect tire damage, immediately reduce speed!
x Check tires and wheel rims for damage.
x If a tire is damaged, do not drive any farther. Get expert assistance.
x If no external damage is visible, slowly and carefully drive to the nearest authorized Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the vehicle checked.
Objects embedded in the tire
x If embedded objects have penetrated to the inside of the tire, do not remove them! If objects are stuck in the tread grooves of the tire, they can be removed.
x With a spare wheel or compact spare wheel: If necessary, change the damaged wheel, Changing a wheel. If necessary, get professional assistance to change the wheel.
x Check tire pressure and adjust if necessary.
Tire wear
Tire wear depends on several factors, including:
x Driving style.
x Unbalanced wheels.
x Wheel alignment.
Driving style – Fast cornering, hard acceleration and braking increase tire wear. If you experience increased tire wear under normal driving conditions, have the vehicle suspension checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Unbalanced wheels – The wheels on a new vehicle are balanced. When driving, however, various conditions can cause a wheel to become unbalanced. Unbalanced wheels can cause wear to the steering and suspension systems. Have all wheels rebalanced. A wheel must always be rebalanced if a new tire has been mounted.
Wheel alignment – Incorrect wheel alignment causes excessive and uneven tire wear, impairing vehicle safety. If you notice excessive or uneven tire wear, have the wheel alignment checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
WARNING
Unusual vibrations or pulling to one side can indicate tire damage.
x Reduce speed immediately and stop when it is safe to do so.
x Check tires and wheel rims for damage.
x Never drive with a damaged tire or rim. Get expert assistance instead.
x If no external damage is visible, slowly and carefully drive to the nearest authorized Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the vehicle checked.

procedure) ⇒ page 257:
TREADWEAR 220 Relative service life expectancy of the tire referenced to a U.S.-specific standard test.
TRACTION A Traction rating under wet conditions (AA, A, B or C).
TEMPERATURE A Temperature stability of the tire at increased test bench speeds (A, B or C).
Additional numbers found on the tire could either be tire manufacturer internal labels or country-specific labels (such as for Brazil and China).
Unidirectional tires
Unidirectional tires are designed to rotate only in one direction. Unidirectional tires have arrows on the sidewalls that show the direction of rotation. Make sure you mount the tire so that it rotates in the proper direction. The tire's performance with regard to hydroplaning, traction, noise, and wear is worse if it is not mounted in the proper direction of rotation.
If you have to mount a tire opposite to its proper direction of rotation, you must drive more carefully, since the tire is no longer being used as designed. This is particularly important on wet roads. You must replace or remount the tire as soon as possible in order to restore the correct direction of rotation.
3 TIN represents the serial number of the tire.

WARNING
Driving faster than the maximum speed for which the winter tires on your vehicle were designed can cause sudden tire failure including a blowout and sudden deflation, loss of control, crashes and serious personal injuries.
x Winter tires have a maximum speed rating that may be lower than your vehicle's maximum speed.
x Never drive faster than the maximum speed for which the winter tires installed on your vehicle are rated because tires that are driven faster than their rated speed can fail suddenly.
x Never exceed the maximum load rating for the winter tires installed on your vehicle.
Install summer tires promptly in the spring. Summer tires offer better handling characteristics for temperatures above +45 °F (+7 °C). They are quieter, do not wear as quickly, and reduce fuel consumption.
If factory-installed wheels and/or tires are replaced when installing winter tires, make sure that the wheels are equipped with sensors that are compatible with the factory-installed Tire Pressure
Monitoring System and that the tires are also compatible with the system⇒ page 238, New and replacement tires,.The Tire Pressure Monitoring System must be recalibrated using the SET button whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change.
If necessary, ask your authorized Volkswagen dealer or authorized Volkswagen Service Facility about permissible winter tire dimensions.
Snow chains

x Temperature: A, B or C
For example: Treadwear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Requirements in addition to these grades.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course.
For example, a tire graded 150 (Treadwear-value 150) would wear one-and-one-half (1 1/2) times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor traction performance ⇒ .
Temperature
The temperature grades are A (the highest), B, and C representing the tire's resistance to the generation of heat, and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law ⇒ .
WARNING
The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning or peak traction characteristics.
WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.
