Daytime running lights (DRL)
Separate lamps are installed in the headlights or in the front bumper for the daytime running lights (DRL).
When the daytime running lights are switched on, only these separate lamps come on ⇒ .
The daytime running lights are switched on whenever the ignition is switched on and the light switch is in position /. The indicator light  or DRL may come on in the instrument cluster to indicate that the feature is active, Lights.
WARNING
Crashes and other accidents can happen when you cannot see the road ahead and when you cannot be seen by other motorists.
x Never use daytime running lights (DRL) to see where you are going. DRL are not bright enough to light up the roadway and be seen by other motorists. You will not be able to see far enough ahead for safety, especially at dusk or when it is dark. Always switch on the low-beam headlights at dusk or when it is dark.
x The taillights do not come on when the daytime running lights are switched on. A vehicle without taillights on cannot be seen by others in bad weather, at dusk, or when it is dark.
In cool or humid weather, the insides of the headlights, the rear lights, and turn signals can temporarily fog up. This is normal and does not affect the service life of the vehicle's lighting system.

WARNING
Unsuitable, worn, or damaged tie-down straps (elastic or non-elastic) can snap or come loose during braking or other maneuvers or in a collision. Objects secured with these straps can then come loose and fly through the passenger compartment, causing severe personal injuries or death.
x To help prevent baggage or other items from coming loose and flying around, always use suitable undamaged tie-down straps.
x Securely fasten the tie-down straps to the tie-downs.
x Loose or improperly secured objects in the luggage compartment can slide about suddenly and change the vehicle's handling.
x Secure even small and light objects. Loose objects in the luggage or passenger compartment can fly about during sudden braking maneuvers or in the event of an accident and injure occupants.
x Never exceed the maximum allowable load on the tie-downs when securing objects.
x Never secure a child seat to the tie-downs.
WARNING
Elastic straps have to be stretched when being attached to the tie-downs in the luggage compartment. Hooks on these straps can cause serious personal injury if not handled properly and attached securely.
x Always protect eyes and face from injury from the hooks when attaching them to the tie-downs in the luggage compartment.
x Always hold the hooks on elastic straps firmly when attaching to the vehicle and do not let them snap back and hit you.
x First attach the hooks on the straps to the tie-downs at the rear seat backrest in the luggage compartment and then to the tie-downs near the loading edge of the luggage compartment. This way, if one of the hooks on the elastic straps snaps back, it will move away from you, decreasing the risk of personal injury.
The maximum load for the tie-downs is about 785 lbs. (356 kg).
For suitable straps and luggage stowage systems, please see an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING
x An improperly installed or incorrect trailer hitch can cause a trailer to separate from the tow vehicle and cause serious personal injuries.
x If you don't have to tow a trailer any more, remove the entire trailer hitch. Always seal all bolt holes to prevent water and deadly exhaust fumes from getting into the vehicle.
NOTICE
x If the trailer lights are not connected properly, the vehicle's electronics may be damaged.
x If the trailer uses too much electricity, the vehicle's electronics may be damaged.
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.
If you tow a trailer frequently, Volkswagen recommends having the vehicle serviced between the regular maintenance and inspection intervals because of the extra load it has to pull.

WARNING
New tires or tires that are old, worn or damaged cannot provide maximum control and braking performance.
x Improper care and handling of tires and wheels can reduce driving safety and cause accidents and severe injuries.
x Install only radial tires of the same make, the same dimensions (tread circumference), and similar tread profile on all 4 wheels.
x New tires tend to be slippery and must be broken in. 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.
x Check tire inflation pressure regularly when the tires are cold and always maintain the prescribed tire pressure. 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 Check tires regularly for wear and damage.
x Never drive with worn or damaged tires (for example, tires with punctures, cuts, cracks, blisters, or bumps). Driving with worn or damaged tires can lead to loss of vehicle control, sudden tire failure including blowouts and sudden deflation, crashes, and serious personal injuries.
x Have worn or damaged tires replaced immediately.
x Never exceed the maximum speed rating or the maximum load rating of the tires on your vehicle.
x The effectiveness of the driver assistance systems and the braking support systems depends on the tire traction.
x If you notice unusual vibration or if the vehicle pulls to one side when driving, always stop as soon as it is safe to do so and check the wheels and tires for damage.
x To reduce the risk of losing control, crashes, and serious personal injuries, never loosen the bolts on wheels with bolted rim rings.
x Never mount used tires on your vehicle if you are not sure of their past use. Old, used tires and wheels may have damage that cannot be seen that can lead to sudden tire failure and loss of vehicle control.
x Tires age even if they are not being used and can fail suddenly, especially at high speeds, causing loss of vehicle control, accidents, and severe personal injuries. Tires that are more than 6 years old can be used only in an emergency and even then only with special care and at low speed.
For technical reasons it is usually not possible to use wheel rims from other vehicles. Even wheel rims from the same model may not fit properly. Check with an authorized Volkswagen dealer or authorized Volkswagen Service Facility if necessary.

If you have to mount a tire opposite to its proper direction of rotation, you must drive more carefully, since the tire is no longer being used as designed. This is particularly important on wet roads. You must replace or remount the tire as soon as possible in order to restore the correct direction of rotation.
Rotating tires
To help ensure even wear on all tires, regular tire rotation according to the diagram ⇒ fig. 88 is recommended. In this way all tires can have about the same service life.
Volkswagen recommends that you have your tires rotated by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Tires more than 6 years old
Tires age even if they are not being used. Physical and chemical processes reduce tire strength and performance and cause them to harden and become brittle. Old tires can fail suddenly and without warning.
Volkswagen recommends replacing tires that are 6 years and older. This also applies to tires that look new (including the tire on the compact spare wheel) or that seem to still be usable with tread depth
that has not yet reached the legal minimum depth ⇒ .
The age of each tire can be determined with the manufacturing date that is part of the U.S. DOT tire identification number (TIN), Tire labeling.
Tire storage
Mark tires before removing them to help make sure that the previous location (left, right, front, rear) and rolling direction can be maintained when remounting them. Store tires in a cool, dry and preferably dark place. Do not store tires mounted on wheels standing up.
Tires not mounted on wheels should be covered to help protect them from dirt and stored vertically (sitting on the tread).
WARNING
Aggressive fluids and materials can cause visible and invisible tire damage that can cause tire blowouts.
x Always keep chemicals, oils, grease, fuels, braking fluids and other aggressive substances away from tires.
WARNING
Tires age even if they are not being used and can fail suddenly, especially at high speeds, causing loss of vehicle control, accidents, and severe personal injuries.
x Tires that are more than 6 years old can be used only in an emergency and even then only with special care and at low speed.
Always dispose of old tires in accordance with legal requirements.
Wheel rims

The design of the wheel bolts is matched to the factory-installed wheels. If different wheels are installed, wheel bolts with the right length and bolt head shape must be used. This helps to ensure that wheels can be mounted securely and that the brakes will work correctly, Changing a wheel.
In most cases, you cannot use wheel bolts from a different vehicle. Even wheel rims from the same model may not fit properly.
