sensor VOLKSWAGEN EOS 2010 User Guide

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.

x Driving without valve caps, with the wrong valve caps, or with valve caps that are not properly screwed on can damage the tire valves and the sensors on the Tire Pressure
Monitoring System ⇒ page 259. To help prevent damage, always use valve stem caps like those originally installed at the factory. The caps must be screwed on tightly. Do not use metal valve caps or “comfort” valve stem caps.
Underinflation increases fuel consumption.
There may be differences between the pressure readings from a tire pressure gauge and the pressures registered by the Tire Pressure Monitoring System. The electronic Tire Pressure Monitoring System is more accurate.
When the TPMS warns that the pressure in at least one tire is too low, check the tire pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be spotted by looking at the tire. This is especially true for low-profile tires. When checking the tire pressures, refer to
Tire inflation pressure in cold tires

Check the tire inflation pressure of the spare or compact spare whenever you check the tire pressure of the road wheels, at least once a month. Inflate a compact spare wheel to the cold tire pressure specified for the compact spare on the tire pressure label or on a separate label for the compact spare, if there is one.
WARNING
Improper use of a compact spare wheel can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a compact spare wheel if it is damaged or worn down to the wear indicators.
x In some vehicles, the compact spare wheel is smaller than the original tire. A smaller compact spare wheel is identified with a sticker and the words “50 mph” or “80 km/h.” This is the maximum permissible speed when driving with this tire.
x Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front axle (drive axle).
x Replace the compact spare with a normal wheel and tire as soon as possible. Compact spare tires are designed for brief use only.
x Regularly check the U.S. DOT Tire Identification Number (TIN) to determine the age of the
compact spare wheel ⇒ page 247, Tire labeling. Tires age even if they are not being used and can fail suddenly, especially at higher speeds.
x Tires that are more than 6 years old can only be used in an emergency and then with special care and at lower speeds.
x The compact spare wheel must always be secured with the wheel bolts provided by the factory.
x Never drive using more than one compact spare wheel.
x After installing the compact spare wheel, the tire pressure must be checked as soon as possible, Tire inflation pressure.
x Snow chains cannot be used on the compact spare wheel. If you must use snow chains and have a compact spare wheel mounted, move the compact spare wheel to the rear axle if a front tire has to be replaced. The tire taken off the rear axle can then be used to replace the flat front tire. Be sure you do not change the tire's direction of rotation. Install the snow chains on the full-sized road tire.
NOTICE
The spare wheel or compact spare wheel has no tire pressure sensor. When the spare or compact spare wheel is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS)
indicator light will flash in the instrument cluster display ⇒ page 259.
If possible, attach the compact spare wheel or the wheel you took off the vehicle securely in the luggage compartment.

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

WARNING
Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control, collision, serious personal injury or even death.
x When the warning symbol appears in the instrument cluster, stop and inspect the tires.
x Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect the handling of the vehicle and stopping ability.
x Incorrect tire pressures and/or underinflation can also lead to sudden tire failure, including a blowout and sudden deflation, causing loss of vehicle control.
x The driver is responsible for the correct tire pressures for all tires on the vehicle. The recommended tire pressure values are listed on a sticker inside the driver door, Tire inflation pressure.
x The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure specified for the tires installed on the vehicle.
x Using incorrect tire pressure values can cause accidents or other damage. Always inflate the tires to the correct specified cold tire pressure values for the tires installed on the vehicle.
x Always maintain correct cold tire inflation pressure so that TPMS can do its job.
x Always inflate tires to the recommended and correct tire pressure before driving off.
x Driving with underinflated tires causes them to flex (bend) more, letting them get too hot, resulting in tread separation, sudden tire failure and loss of control.
x Excessive speed and/overloading can cause heat build-up, sudden tire failure, and loss of control.
x If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well.
x If the tire is not “flat” and you do not have to change a wheel immediately, drive carefully and at reduced speed to the nearest service station to check the tire pressure and add air as required.
x When replacing tires or wheel rims on vehicles equipped with TPMS always read and heed the information and all WARNINGS regarding Tires and wheels, Tires and wheels.
NOTICE
x The wheel electronics are attached to special aluminum valves on the wheels. These valves are screwed on rigidly. Never bend the valves “into position” when checking and adjusting tire pressure.
x Missing valve stem caps can cause damage to the valves as well as to the TPMS sensors. To help prevent damage, always use valve stem caps like those originally installed at the factory. The caps must be screwed on tightly. Do not use metal valve stem caps.
x Do not use “comfort valve caps.” They do not seal properly and can damage the sensors.
x When replacing or rotating tires, make certain the valves and sensors are not damaged.
x The aluminum valves that are installed should be replaced after about 6 years of use because of aging in the rubber seals. The valves can be replaced when a tire is changed. Do not reuse aluminum valves after they are removed. They must be replaced. The tire pressure sensor can be reused.
x When replacing the valve cores, use only nickel-plated replacement cores.
x The batteries in the wheel electronics last up to 10 years. It is not possible to replace the batteries. The entire device must be replaced.
Underinflation increases fuel consumption and tire wear.

Dispose of the wheel electronics and the old batteries in an environmentally responsible manner. Batteries of the type used in the wheel electronics may contain Perchlorate Material. Special handling may apply. See www.dtsc.ca.gov/hadardouswaste/perchlorate. Obey all applicable legal requirements regarding proper disposal.
Do not rely only on the Tire Pressure Monitoring System. Check your tires regularly to make sure 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 tire tread but have not penetrated into the body of tire itself.
The Tire Pressure Monitoring System checks for the factory-recommended inflation pressure, as shown on the label inside the driver door, Tire inflation pressure.
x For replacement tires that require a different inflation pressure, the TPMS must be adjusted to the new pressure specification by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Only one value can be entered for each tire; see the tire inflation pressure label on the driver
door pillar ⇒ page 240, Tire inflation pressure.
x To help prevent damage to the sensor and valve, do not put excessive force on the valve when checking the tire pressure. Do not try to bend the valve.
x If sensors have to be replaced, have the valves changed at the same time.
x The tire valve gaskets must be replaced whenever a tire is mounted on the rim. Your authorized Volkswagen dealer or authorized Volkswagen Service Facility has a valve seal and gasket kit for this purpose. Always make sure that a valve seal and gasket kit is also used whenever a sensor is replaced.
x If you have to adjust the tire pressure on a “warm” tire, fill the tire with 2.0 - 4.35 psi (20 - 30 kPa) more than the pressure specified on the tire pressure label.
x When the TPMS determines that the air pressure in at least one tire is too low, carefully check the pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be determined by looking at the tire. This is especially true of low-profile tires.
A Declaration of Compliance with the United States FCC and Industry Canada regulations is found in the Consumer Information section of this Manual, Declaration of Compliance, Telecommunications and Electronic Systems.
There may be differences between the pressure readings from a tire pressure gauge and the pressures registered by the Tire Pressure Monitoring System. The electronic TPMS is more accurate.
If you have work done on your wheels or tires, inform the workshop that the vehicle is equipped with a Tire Pressure Monitoring System that has sensors in the wheels.

your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
Spare wheel or compact spare wheel
The spare wheel or compact spare wheel has no tire pressure sensor. When the spare or compact spare wheel is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS) indicator light will flash in the instrument cluster display. The TPMS continues to monitor the other 3 wheels.
Tire storage
If the tires do not move for an extended period of time, the sensors will not transmit tire pressures to the system. This saves sensor battery life. The sensors are reactivated by driving the vehicle again.
WARNING
Incorrect tire pressure can cause sudden tire failure, loss of vehicle control and serious personal injury.
x Always check and correct air pressure in all 4 tires, particularly after changing, exchanging, or repairing tires.
x After that, always make sure that all 4 tires are inflated to the correct tire pressure for the tires installed on the vehicle.
x See the tire pressure label ⇒ fig. 104, Tire inflation pressure and the Owner's Literature for recommended cold tire inflation pressure and other important information.
x When replacing tires or wheel rims on vehicles equipped with TPMS, always read and heed all of the information and WARNINGS, Tires and wheels.
NOTICE
x The wheel electronics are attached to special aluminum valves on the wheels. These valves are screwed on rigidly. Never bend the valves “into position” when checking and adjusting tire pressure.
x Missing tire air valve caps could result in damage to the valves, as well as to the sensors on the Tire Pressure Monitoring System. Therefore, make sure your valve caps conform to the specifications of those originally installed on the vehicle and that they are always tightly and properly screwed on to the valves. Do not use metallic valve caps
x Do not use “comfort valve caps.” They do not seal properly and can damage the sensors.
x When changing or rotating the tires, be careful not to damage the valves or sensors.
x The aluminum valves that are installed should be replaced after about 6 years of use due to aging of the rubber seals. The valves can be replaced when a tire is changed. Do not reuse aluminum valves after they are removed. They must be replaced. The tire pressure sensors can be reused.

To help make it more difficult to steal your vehicle, you should always make sure the steering column is locked before leaving the vehicle.
Electronic steering column lock
Vehicles with Keyless Access: The steering column is locked if the driver door is opened with the ignition switched off. The vehicle must be standing still and the transmission must be in Park (P) on an automatic transmission vehicle.
If the driver door is opened before the ignition is switched off, the electronic steering column lock is activated only after the vehicle has been locked with the vehicle key or via the sensor in the door handle.
Mechanical steering column lock
Vehicles without Keyless Access: The steering column is locked if the vehicle is stationary and the vehicle key is removed from the ignition switch.

Engaging the steering column lock Disengaging the steering column lock
Parking the vehicle Turn the steering wheel slightly to take pressure off the steering column lock.
Remove the vehicle key. Insert the vehicle key into the ignition switch.
Turn the steering wheel slightly until you hear the steering column lock engage.
Hold the steering wheel in this position and turn the ignition switch.

Power steering
Power steering automatically adjusts to driving speed, steering torque, and the steering angle of the wheels. Power steering works only when the engine is running.
If power steering is reduced or lost completely, it will be much harder to steer and control the vehicle.
Counter-steering assistance
Counter-steering assistance is part of Electronic Stability Control (ESC). This feature makes it easier for the driver to control the vehicle in difficult situations. For example, if you have to brake hard on a surface that provides uneven traction, the vehicle could pull to the right or left. ESC detects this
situation and helps the driver counter-steer with additional steering power ⇒ .
WARNING
The counter-steering assistance in ESC can do no more than help the driver steer in difficult situations. The driver must still control the vehicle. The vehicle does not steer by itself with this feature!
NOTICE
If the ignition is off, the steering column lock will engage and the vehicle cannot be steered. For this reason, you must leave the ignition on when going through an automatic car wash, for example, so that the wheels will still steer.
