DOT BT RA TY5 1709 Tire identification number (TIN3 - In some cases
the manufacturing date is only on one side of the
tire:
DOT The tire complies with the requirements of
the United States Department of Trans-
portation, responsible for issuing safety
standards.
BT Identification letter of the manufacturing
site.

dimensions.
TY5 Tire characteristics provided by the
manufacturer.
1709 Manufacturing date: 17th week in 2009.
3 TIN represents the serial number of the tire.
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
Tire dimensions Rim
255/60 R17 7 1/2 J x 17 ET 55
255/55 R18 8 J x 18 ET 57
Please contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility about appropriate wheel, tire and snow chain dimensions.
If possible, use only chains with low profile links that are not thicker than 37/64 in (15 mm) including the tensioner.
Remove center hubcaps and decorative rim rings before installing snow chains ⇒ . However, for safety reasons, caps must be installed on the wheel bolts. These are available from authorized Volkswagen dealers and authorized Volkswagen Service Facilities.
Collapsible spare
For technical reasons, snow chains cannot be used on the collapsible spare ⇒ Collapsible spare tire.
If you must use snow chains and have a collapsible spare tire mounted, move the collapsible spare 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 vehi-cle.
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.
Snow chains are available in different sizes for each vehicle model.
Glossary of tire and loading terminology
If the battery was disconnected for a long time, the next scheduled service may not be correctly calcu-lated and displayed. The maximum permissible service and maintenance intervals are shown in the
⇒ Booklet Warranty and Maintenance.
Vehicles with Keyless Access
If the ignition will not start after reconnecting the vehicle battery, lock the vehicle from the outside and unlock it again. Then try to start the ignition again. If the ignition cannot be switched on, contact an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified work-shop for assistance.
Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent on-board electrical system management automatically takes steps to help prevent battery drain.
x The idle speed is increased so that the alternator provides more power.
x The power to devices that consume a lot of electricity is cut back or switched off completely.
x When the engine is started, the power supply to the 12 Volt sockets and the cigarette lighter is temporarily interrupted.
The on-board electrical system management cannot always keep the battery from being drained. For example, the battery will drain if the engine is not running, but the ignition is switched on or the parking lights are left on for a long time when parked.
Battery disconnection in an accident with airbag deployment
In vehicles with a battery in the luggage compartment, the electrical connection to the battery is dis-connected automatically in a collision with airbag deployment. This helps to prevent a short-circuit.
What drains the vehicle battery?
x Long periods when the engine is not running, especially when the ignition is on.
x Using electrical systems or devices when the engine is switched off.
x Leaving the vehicle unlocked for several days when not in use.
x The selector lever is left for a long period of time in any position other than (P) when the ignition is
switched off ⇒ Automatic transmission: Selector lever.
WARNING
Failure to use the proper battery with proper mounting and connections may cause short circuits, fires, and serious personal injuries.
x Always use only maintenance-free or cycle-free, leak-proof batteries with the same speci-fications and dimensions as the original equipment battery. Specifications are listed on the battery housing.
WARNING
When the vehicle battery is charged, it produces highly explosive hydrogen gas.
x Charge vehicle batteries only in well-ventilated areas.
x Never charge a frozen or thawed battery. A dead battery can freeze at temperatures around +32 °F (0 °C). Always replace a battery that has frozen.
x You must replace the vehicle battery if it was frozen.
x Incorrectly connected cables can cause a short-circuit. First connect the positive cable (+) and then the negative cable (-).
