“Leaving home” Action
– Lock the vehicle.
– Turn the light switch to the / position.
– Switch on the ignition.
Background lighting in the outside mirrors
The background lighting in the outside mirrors lights up the area close to the doors while you are getting into or out of the vehicle. It is switched on when the vehicle is unlocked, a vehicle door is opened, or the “Coming home” or “Leaving home” feature is activated. If the vehicle is equipped with a light sensor, the background lighting in the outside mirrors is only switched on in darkness.
The lights stay on for about 10 seconds (lighting delay period). The “Coming home” and “Leaving home” features can be enabled and disabled in the Infotainment System.
If the “Coming home” feature is switched on and the driver door is opened, no acoustic warning will sound to alert that the light is still on.

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. 97 (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.

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. 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 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 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 failure, 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 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. 113 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. 113 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 blowouts.
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 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 damage 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 Monitoring System. 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 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 ⇒ 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.
