Volkswagen recommends that you have an authorized Volkswagen dealer or authorized Volkswagen Service Facility install the hitch receiver, electrical system and socket.
A ball mount and ball combination that does not meet these specifications can damage your vehicle
and may even fail in use ⇒ .
Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The vehicle is not
designed for this kind of trailer hitch ⇒ .
WARNING
An improperly installed or unsuitable trailer hitch can cause the trailer to separate from the towing vehicle and result in a major accident with serious personal injuries.
x Have any trailer hitch retrofit or other work on a trailer hitch done by a qualified workshop.
CAUTION
The ball mount sticks out behind the rear bumper and can cause injury to pedestrians and cyclists.
x To reduce the risk of injury in rear-end collisions, and the risk to pedestrians and cyclists when the vehicle is parked, always remove the ball carrier when you are not towing a trailer.
NOTICE
x Never use a hitch ball larger than 2 inches (51 mm) on your vehicle. The vehicle was not designed to tow heavier trailers with a receivers larger than the specified ball. The increased loads can damage the attachment points for the trailer hitch.
x Never use an adapter to increase the size of the trailer hitch receiver from 2 inches to a larger size to tow a trailer that is heavier than the maximum permissible trailer weight that your vehicle can tow.
x You can use an adapter if required for the proper installation of a bicycle rack or other similar carrier as long as the maximum weight limits are observed. When using bicycle racks or similar carriers, make sure that the rear lights are not blocked.
x Only use trailer hitches that are approved by the hitch manufacturer for your vehicle and model.

x After installing the compact spare wheel, check the tire pressure as soon as possible ⇒  Tire inflation pressure.
Check the tire inflation pressure of the compact spare whenever you check the tire pressure of the road wheels, at least once a month. Inflate a compact spare tire 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 compact spare wheel can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a compact spare tire if it is damaged or worn down to the wear indicators.
x In some vehicles, the compact spare tire is smaller than the original tire. A smaller compact spare tire 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 wheels 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 tire ⇒  Tire labeling. Tires age even if they are not being used and can fail suddenly, especially at higher speeds.
x 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 low 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 start flashing after about 10 minutes.
If possible, attach the compact spare wheel or the wheel you took off the vehicle securely in the luggage compartment.

d Check the vehicle tool kit. Add tools and other gear based on the special requirements of the trip you will be taking
d Stow luggage as low and flat as possible in the vehicle. Safely secure all loose objects.
Before driving off-road the first time
Before you drive your vehicle off-road, we urge you to take an appropriate off-road driving course. Taking a course is especially important if you have little or no experience driving off-road. Even more experienced off-roaders can benefit from an off-road driving course.
A good course can show you how to handle the vehicle in a wide range of off-road situations and how to more safely deal with difficult terrain Driving off-road demands a different attitude and very different skills compared with highway driving. Your safety and that of your passengers will depend on your
knowledge, skill, and caution as a driver ⇒ .
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist above. Follow commonly accepted safety practices and use common sense.
x All occupants must sit properly and wear safety belts whenever the vehicle is moving.

x To help prevent damage to the engine hood and the windshield wiper arms, lift the wiper arms away from the windshield only when they are in the service position.
Waxing and polishing vehicle paint

Changing the vehicle's suspension system can change the way that the airbag system works in a crash. For example, using tire-rim combinations not approved by Volkswagen, lowering the vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock absorbers etc. can change the forces that are measured by the airbag sensors and sent to the electronic control unit. Some suspension changes can, for example, increase the force levels measured by the airbag sensors and sent to the electronic control unit and make the airbag system deploy in crashes in which it would not deploy if the changes had not been made. Other kinds of changes may reduce the force levels measured by the sensors and prevent the airbag from deploying when it should.
Never install leather upholstery on a vehicle that originally had cloth upholstery. Never install cloth upholstery on a vehicle that originally had leather upholstery. The weight-sensing mat for the Advanced Airbag system will not work properly if different upholstery is installed on the passenger seat than the upholstery originally installed on the vehicle when it was originally manufactured.
WARNING
Changing the vehicle's suspension including use of unapproved tire-rim combinations can change airbag performance and increase the risk of serious personal injury in a crash.
x Never install suspension components that do not have the same performance characteristics as the components originally installed on your vehicle.
x Never use tire-rim combinations that have not been approved by Volkswagen.
WARNING
Leaving the optional safety belt extender attached to the safety belt buckle on the front passenger seat when the safety belt is not being used will prevent the Advanced Airbag System from working properly and can increase the risk of serious personal injury in a collision.
x Leaving the extender attached to the safety belt buckle when the front seat is occupied and the safety belt is not being used will signal to the airbag control unit that the front passenger seat is occupied and that the safety belt is being used. The electronic control unit for the airbag system will then receive incorrect information that will
– cause the safety belt pretensioner to deploy unnecessarily in collisions and
– cause the front passenger airbag to deploy later in collisions in which the front airbag would otherwise be triggered earlier to help protect an unrestrained front seat passenger.
x Always remove the safety belt extender when it is not needed and stow it safely.
x Never use the safety belt extender to secure a child restraint.
WARNING
Items stored between the safety belt buckle and the center console can cause safety belt buckle to send the wrong information to the airbag control unit and prevent the Advanced Airbag System from working properly.
x Always make sure that nothing can interfere with the safety belt buckles and that they are not obstructed.

Limits and guidelines have been established by governmental authorities and international committees in an effort to keep the electromagnetic radiation from mobile phones at levels that will not cause health problems. However, there is no scientifically based proof that wireless phones are absolutely safe.
Therefore some experts recommend a precautionary approach regarding the use of mobile phones by taking measures that lower the personal exposure to electromagnetic fields.
When using a mobile phone inside a motor vehicle without a proper connection to an integrated vehicle telephone antenna, the personal exposure to electromagnetic fields will be higher than when using the mobile telephone while properly connected to an integrated or other outside vehicle telephone antenna.
Your vehicle may be equipped with an optional hands-free system that will permit many of the features of compatible Bluetooth® enabled mobile telephones to be used for greater convenience and is consistent with the laws of an increasing number of states and localities that prohibit the use of mobile telephones without some kind of hands-free device.
The hands-free system in your vehicle can be used with certain mobile phones that are connected by wire and hardware connector or via compatible Bluetooth® enabled phones with a cradle that is designed to fit your mobile telephone. The special cradle offers several advantages: The phone cradle must be safely secured to the base plate. Your phone is firmly attached to the instrument panel and is within reach at all times. Placing the phone in its cradle permits it to be charged, but more importantly connects the mobile phone to the vehicle's outside antenna. A mobile telephone that is properly connected to the integrated or other outside vehicle telephone antenna will lower the personal exposure to electromagnetic fields. You should also experience a better quality of service. Although a mobile telephone can be used inside your vehicle without a cradle, the phone will not be securely attached to the vehicle, will not be charged through the cradle wiring, and more importantly will not be connected to the vehicle's integrated telephone antenna. The mobile phone will also not be recharged. You might also experience more dropped calls and an overall impaired quality of the connection.
Therefore we strongly recommend that you use your mobile telephone in your vehicle only when it is properly attached to an appropriate cradle mounted on a base plate on the instrument panel.
Because of the large number and variety of mobile telephones on the market and the frequency with which new models are introduced, Volkswagen does not offer cradles for mobile telephones. Please check with the manufacturer of the mobile telephone that you plan to use.

WARNING
A mobile phone on the seat, instrument panel or in other places can be thrown around the inside of the vehicle during a sudden braking maneuver, a crash or other accident and injure vehicle occupants.
x Never place or attach accessories or other objects (such as cup holders, telephone brackets, notepads, navigation systems, large, heavy or bulky objects) on the doors, on the windshield, over or near the area marked “AIRBAG” on the steering wheel, instrument panel, backrests or between these areas and the occupant. Such objects could cause serious injury in a collision, especially if an airbag inflates.

6. Have all passengers exit and go to a safe place, such as behind a guard rail.
7. Block the diagonally opposite wheel with chocks from vehicle tool kit or other suitable things.
