compartment ⇒ Storage.
x If applicable, remove the subwoofer ⇒ Removing the subwoofer.
x If necessary, pull the securing clip ⇒ fig. 105 (1) out and up.
x Completely unscrew the handwheel in the center of the spare wheel (2) or compact spare wheel
⇒ fig. 106 counterclockwise and remove the spare wheel.
Stowing the replaced wheel
x Open the rear hatch, lift up the floor covering, and hook it in the stops on either side of the luggage compartment.
x If the wheel you took off the vehicle fits in the spare wheel well, position it so that the center hole of the rim is aligned with the threaded pin in the center of the well.
x Turn the handwheel ⇒ fig. 105 (2) clockwise until the wheel is securely in place.
x If necessary, insert the securing clip (1) in the stud slot so that the handwheel can no longer be turned.
x If necessary, return the vehicle tool kit to its location in the luggage compartment.
x Unhook the floor covering and fold it back down onto the floor of the luggage compartment.
x Close the rear hatch.
If the replaced wheel does not fit in the spare wheel well, stow it securely in the luggage compartment on top of the floor covering.
If the spare wheel is different from the road wheels
If the spare is different from the road wheels, a compact spare wheel, for example, or if the road wheels are winter tires, the spare wheel must be used only in the event of a flat tire, only for a brief
time, and only when driving with extra caution ⇒ .
Replace it with a tire matching the others on your vehicle as soon as possible.
Please heed the following:
x Do not drive faster than 50 mph (80 km/h)!
x Avoid full-throttle acceleration, hard braking, and fast cornering!
x Do not use snow chains on the compact spare wheel ⇒ Snow chains.
x After installing the spare wheel or compact spare wheel, check the tire pressure as soon as
possible ⇒ Tire inflation pressure.
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 spare wheel to the cold tire pressure specified for the vehicle's road wheels on the tire pressure label; 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 spare wheel or a compact spare wheel can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a spare wheel or compact spare wheel if it is damaged or worn down to the wear indicators.
x In some vehicles, the spare wheel or 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 ⇒ 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
When the spare wheel or compact spare is being used, the TPMS indicator light can light up
after a couple of minutes ⇒ Tire Pressure Monitoring System (TPMS).
If possible, attach the spare wheel, compact spare wheel, or the wheel you took off the vehicle securely in the luggage compartment.

WARNING
Using incorrect or unmatched tires and/or wheels or improper tire and wheel combinations can lead to loss of control, collision and serious personal injury.
x Always use tires, wheels and wheel bolts that meet the specifications of the original factory-installed tires or other combinations that have been specifically approved by the vehicle manufacturer.
x All 4 wheels must be fitted with radial tires of the same type, the same size (tread circumference), and the same tread pattern. Driving with different tires reduces vehicle handling and can lead to a loss of control.
x Never drive faster than the maximum speed for which the tires installed on your vehicle are rated because tires that are driven faster than their rated speed can fail suddenly.
x Overloading tires can cause heat build-up, sudden tire failure, including a blowout and sudden deflation and loss of control.
x Temperature grades apply to tires that are properly inflated and not over- or underinflated.
Winter tires

Compact spare wheel
For technical reasons, snow chains cannot be used on the compact spare ⇒ Spare wheel or 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 to install the unidirectional tires so that they will run in the proper direction. Volkswagen recommends installing the snow chains before mounting the wheel to the vehicle.
WARNING
Using the wrong snow chains or installing snow chains improperly can cause accidents and severe personal injuries.
x Always use the proper snow chains.
x Follow the installation instructions provided by the snow chain manufacturer.
x Never exceed the permissible speed limit when driving with snow chains.
NOTICE
x Remove snow chains when roads are free of snow. Otherwise, the chains can damage the tires, impair vehicle handling and can be quickly worn down.
x Snow chains can scratch or damage wheel rims if they have direct contact with the rims. Volkswagen recommends using coated snow chains.
Glossary of tire and loading terminology

Recommended inflation pressure
The tire pressure recommended by the vehicle manufacturer for a tire of a specified size that has not been driven for more than a couple of miles (kilometers) at low speeds in the 3 hour period before the tire pressure is measured or adjusted.
Reinforced tire
A tire designed to operate at higher loads and at higher inflation pressures than the corresponding standard tire.
Rim
The outer edge of a wheel upon which the tire beads are seated.
Rim diameter
The nominal diameter of the wheel's tire bead seating surface. If you change your wheel size, to wheels of a different diameter, you will have to purchase new tires to match the new wheels.

of their useful life ⇒ page 169.
Uniform Tire Quality Grading (UTQG)
A tire information system developed by the U.S. National Highway Traffic Safety Administration (NHTSA) that is designed to help buyers compare tires. UTQG is not a safety rating, nor is it a guarantee that a tire will last for a certain number of miles or perform a certain way. It gives tire buyers more information to compare with factors such as price, brand loyalty and dealer recommendations. Under UTQG, tires are graded by the tire manufacturers in 3 areas: tread wear, traction and temperature resistance. UTQG information is molded into the tire sidewalls.

U.S. DOT Tire Identification Number (TIN)
A tire's serial number. It begins with the letters “DOT” (“Department of Transportation”) and indicates that the tire meets all federal standards. The next 2 numbers or letters indicate the plant where the tire was manufactured. The last 4 numbers represent the week and year of manufacture.
For example, the numbers 1709 mean that the tire was produced in the 17th week of 2009. Any other numbers are marketing codes used by the tire manufacturer. This information is used to help identify affected consumers if a tire defect requires a recall.

Tires and vehicle load limits

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.
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 buildup, 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.
x The Tire Pressure Monitoring System must be recalibrated 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 ⇒ Tire inflation pressure.
WARNING
Improper recalibration can cause the TPMS to give false warnings or to give no warning
despite dangerously low tire pressure ⇒ Tire Pressure Monitoring System (TPMS) and recalibration through the Infotainment system.
Underinflation increases fuel consumption and tire wear.
Do not rely solely 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.
