2017 VOLKSWAGEN TOUAREG sensor

The trailer is connected to the anti-theft alarm (if equipped):
x When the vehicle has a factory installed anti-theft alarm and a factory installed trailer hitch.
x When the trailer is not equipped with LED taillights.
x When the trailer is electrically connected to the towing vehicle via the trailer socket.
x When the vehicle and trailer electric systems are functional, fault-free and undamaged.
x When the vehicle is locked with the remote control vehicle key and the anti-theft alarm is active.
When the vehicle is locked, the alarm will be triggered as soon as the electrical connection to the trailer is interrupted.
Always switch off the anti-theft alarm when a trailer is being hitched or unhitched. The tilt sensor could otherwise trigger an alarm unnecessarily.
WARNING
Improper connections to the vehicle electrical system can cause malfunctions that affect the entire vehicle electrical system, which can lead to accidents and serious personal injury.
x Have any work on the electrical system done by an authorized Volkswagen dealer or au-thorized Volkswagen Service Facility.
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.
NOTICE
Never attach a trailer to the vehicle or leave it attached to the vehicle when the trailer is sup-ported by a trailer jack or blocks. Various things (such as a change in trailer or vehicle load or a flat tire) can lower or raise the vehicle. This subjects the trailer hitch and the trailer to strong forces that can damage the vehicle or the trailer.
Any problems with the vehicle's electrical system when attached to a trailer should be checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
If the engine is switched off and accessories in the trailer are on and use electricity from the vehicle, the vehicle battery will be drained as long as the electrical systems of the vehicle and the trailer are connected.
For technical reasons, trailers with LED taillights cannot be integrated into the anti-theft alarm system.
Loading the trailer

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 sys-tem. The new wheels and sensors are recognized and integrated when driving off the first time.
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 pres-sure 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 author-ized 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 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 malfunction of the TPMS, and is not recommended (cord material information in 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 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 fail-ure, tread delamination, and sudden blow outs.
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 could be damaged.
x If the sensor on the Tire Pressure Monitoring System (TPMS) 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 or 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. 111 Location of the tire inflation pressure label.

The correct tire inflation pressure for factory-installed tires is listed on a label. The factory-installed
tires may be summer, winter, or all-season tires. The label ⇒ fig. 111 is on the driver door jamb.
Under- or over-inflation significantly shortens the service life of your tires and affects the handling of
the vehicle ⇒ . The correct tire pressure is very important, particularly when the vehicle is driven at higher speeds. Incorrect tire pressure causes increased wear and even sudden tire failure and blow-outs.
Therefore tire pressure should be checked at least once a month and always before long trips.
The specified tire inflation pressure applies to a cold tire. When tires are warm, the pressure will be higher than when the tires are cold.
Do not reduce the tire pressure on warm tires to match the required cold tire inflation pressure. The tire inflation pressure would then be too low and could cause sudden tire failure and blowout.
Checking tire inflation pressure
Always check the tire pressure on “cold” tires when the vehicle has not been driven more than a couple of miles (kilometers) at low speed within the last 3 hours.
x Check tire inflation pressure regularly and on cold tires. Check all the tires, including the collapsible spare (if any). In colder climates tire pressure should be checked more often, but only when the tires are cold. Always use an accurate tire pressure gauge.
x After adjusting the tire inflation pressures, make sure to screw the valve caps back on, replace missing valve caps immediately. Please read and heed the information on resetting the Tire Pressure
Monitoring System (TPMS) if necessary ⇒  Tire Pressure Monitoring System (TPMS).
x Remember that the vehicle manufacturer, not the tire manufacturer, determines the correct tire pressure for the tires on your vehicle. Never exceed the maximum inflation pressure listed on the tire sidewall for any reason.
Inflate the spare wheel to the pressure specified for the vehicle's road wheels on the tire pressure label; inflate a compact spare wheel to the 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
Incorrect tire pressure can cause a sudden tire failure, or blowout, loss of control, collision, serious personal injury, and even death.
x Always inflate tires to the recommended and correct cold tire pressure before driving off.
x 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 Excessive speed and/or overloading can cause heat buildup, sudden tire failure including a blowout and sudden deflation 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 Regularly check tire inflation pressure, at least once a month, and also especially before a long trip.
x Check the pressure in all 4 tires when the tires are still cold. Never reduce air pressure in warm tires to match cold tire inflation pressure.
NOTICE
x Make sure not to jam the tire pressure gauge into the valve stem. Otherwise you can dam-age the tire valves and the tire inflation pressure sensors.

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 Monitor-ing System (TPMS). 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.
Pressures measured with a gauge when inflating the tires may be different from the pressures read by the tire pressure sensors. The electronic TPMS 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 Pressure Monitoring System (TPMS).
Tire inflation pressure in cold tires

All-wheel drive (4MOTION)
Vehicles with all-wheel drive and standard road wheels have good forward motion and traction even under wintery road conditions. However, Volkswagen recommends installing snow tires or all season tires on all 4 wheels to improve handling as well as braking performance.
If you use snow chains, please read and heed information and directions ⇒  Snow chains.
WARNING
Driving faster than the maximum speed for which the winter tires on your vehicle were de-signed can cause sudden tire failure including a blowout and sudden deflation, loss of con-trol, 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 con-sumption.
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 (TPMS) and that the tires are also compatible with the system ⇒  Tire Pressure Monitoring System (TPMS). If new tires are not identical to those that were removed and require different cold tire inflation pressure, the tire inflation pressure values must be reprogrammed for the
TPMS. Please see your authorized Volkswagen dealer or authorized Volkswagen Service Facility ⇒  Tire Pressure Monitoring System (TPMS).
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, includ-ing 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 on the driver door ⇒  Tires and wheels.
x The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire 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 facto-ry. 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 switching to different tires, make certain the valves and sensors are not damaged.
x When replacing the valve cores, use only nickel-plated replacement cores.
x The batteries in the wheel electronics have a life of 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 http://www.dtsc.ca.gov/hadardouswaste/perchlorate. Obey all applicable legal re-quirements regarding proper disposal.
Do not rely solely on the Tire Pressure Monitoring System (TPMS). 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.
When you take delivery of the vehicle, the Tire Pressure Monitoring System (TPMS) is calibrated for the factory-recommended cold tire inflation pressure for the tires on your vehicle, as shown on the
label inside the driver door ⇒ fig. 111.
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 partial or full load; see the tire inflation pressure
label on the driver door pillar ⇒  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 re-placed.
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 deter-mined by looking at the tire. This is especially true of low-profile tires.
x A Declaration of Compliance with the United States FCC and Industry Canada regulations is found on of this manual.
There may be differences between the pressure readings from a tire pressure gauge and the pressures registered by the Tire Pressure Monitoring System (TPMS). 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 (TPMS) that has sensors in the wheels.
New tires may expand slightly the first time they are driven at high speeds, which can trigger a tire pressure warning. Remember that tire pressure can only be properly measured when the tire is
“cold” ⇒  Tires and wheels.
