Possible reasons for changes in the way the rain sensor works
The rain sensor may misread what is happening in the detection zone of its sensitive rain-sensor
surface ⇒ fig. 95 (arrow) and not work for a number of reasons, which include:
x Worn out wiper blades: Worn out wiper blades may leave a film of water or wiping streaks; this can cause the wipers to run longer, to wipe more often, or to wipe continuously at high speed.
x Insects: Insects hitting the sensor cause wiping.
x Salt streaks: Salt streaks on the windshield from winter driving can cause wiping more often or continuously on glass that is almost dry.
x Dirt: Caked-on dust, wax, any other buildup on the windshield (lotus effect), or car-wash detergent residue can lower the rain sensor's sensitivity and cause it to react too slowly or not at all.
x Crack in the windshield: If a stone hits and chips the sensitive surface while the rain sensor is on, this will trigger a wiper cycle. After that, the rain sensor will recognize the change and recalibrate itself to respond to the smaller detection zone. Depending on the size of the chip, the sensor's reaction pattern may or may not change.
WARNING
The rain sensor cannot always recognize rain and activate the wipers.
x Switch the wipers on manually when water on the windshield reduces visibility.
Clean the sensitive area of the rain sensor regularly and check the wiper blades for wear or damage.
To remove wax and coats of polish safely, we recommend using an alcohol-based windshield cleaner.

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.
