These dimensions are important because they help determine the way that the forces that arise during towing are applied to the receiver and its attachments to the vehicle. If you buy a ball mount and ball, make sure that they meet the following specifications.
Ball mount dimensions
x The drop height (A) from the center of the ball to the center of the hole for the securing pin on the ball mount must be at least 1 inch (25.4 mm) and at most 27/8 inches (73 mm).
x The pin-to-ball distance (B) from the center of the ball to the center of the hole for the securing pin on the ball mount must be no more than 7 inches (178 mm).
x The ball diameter must be no more than 11/4 inches (32 mm).
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 ball larger than 11/4 inches (32 mm) on your vehicle. The vehicle was not designed to tow heavier trailers with a receiver 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 11/4 inches (32 mm) to 2 inches (50.8 mm) or more 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.

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.
Tires and wheel rims approved by Volkswagen have been matched precisely to your vehicle model and contribute considerably to good handling and safe vehicle performance.
Tightening torque
Wheel bolts must always be installed with the correct tightening torque ⇒ Changing a wheel. The required tightening torque for your vehicle's wheel bolts is 88 ft-lbs (120 Nm). After changing a wheel, the bolt torque must be checked as soon as possible with an accurate torque wrench. See an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Wheel rims with bolted rim rings
Wheel rims with bolted rim rings have several parts. The parts are bolted together with special screws in a special process. This helps to ensure that they will work properly, prevent leaks, run true and safely. Damaged wheel rims must be replaced, and you must never take them apart or try to repair them yourself. Have an authorized Volkswagen dealer or an authorized Volkswagen Service Facility
repair them for you ⇒ .
Wheel rims with bolted decorative covers
Light-alloy wheels may have interchangeable decorative covers attached to the rim with self-locking screws. If you want to replace damaged wheel covers, contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
WARNING
Using improper or damaged wheel rims can affect driving safety, cause accidents and severe personal injury.
x Use only wheel rims approved for the vehicle.
x Regularly check wheel rims for damage and replace them if necessary.
WARNING
Improper loosening and tightening of the bolts on wheel rims with bolted rim rings can cause accidents and severe personal injury.
x Never loosen bolted connections on wheel rims with bolted rim rings.
x Have all work on wheel rims with bolted rim rings performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
New and replacement tires

Removing the spare wheel or compact spare wheel

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.

Only use floor mats that leave the pedal area free and are held securely in place with floor mat fasteners to help prevent sliding.
If a brake circuit malfunctions, more brake pedal travel is needed to bring the vehicle to a full stop, and it is important that nothing is in the way when you have to depress the brake pedal harder and farther than normal.
WARNING
Objects in the driver footwell can prevent the pedals from moving freely. This can cause loss of vehicle control and increase the risk of serious personal injuries.
x Always make sure that nothing can interfere with the pedals.
x Always fasten floor mats securely to the floor.
x Never put floor mats or other floor coverings on top of already installed floor mats.
x Always make sure that nothing can fall into the driver footwell while the vehicle is moving.
NOTICE
Always make sure that the pedals are able to move freely and that nothing can interfere with them. If a brake circuit fails, more brake pedal travel will be needed to bring the vehicle to a stop. The brake pedal must be pressed farther and harder than normal.

(A): Do not add any oil ⇒ . Continue with step 15.
(B): Oil may be added, depending on the oil level. Continue with step 8 or step 15.
(C): You must add oil (about 1 quart / 1.0 liter). Continue with step 8.
8. After reading the oil level, reinsert the dipstick back into the guide tube and push it all the way in.
9. Remove the cap on the engine oil filler opening ⇒ fig. 157.
10. Only add engine oil that Volkswagen has approved for that engine. Add the oil gradually in small quantities (no more than 1 pint / 0.5 liter).
11. To help prevent overfilling, you must wait about 1 minute each time you add oil so that the oil can flow into the oil pan up to the marking on the dipstick.
12. Read the oil level on the dipstick again before adding another small amount, if necessary. Never
add too much oil ⇒ .
13. After adding oil, the level must at least be in the center of the ⇒ fig. 156 (B) area, but never above
(B) ⇒ .
14. After adding oil, securely install the cap on the engine oil filler opening. Otherwise, oil could leak out while the engine is running.
15. Insert the oil dipstick back in the guide tube and push it all the way in.
16. Close the hood ⇒ .
Engine oil level ranges

Required action according to the respective engine oil level:
Range (A) Do not refill oil ⇒ .
Range (B) You may add oil, as long as the oil level does not go above the (B) range.
Range (C) You must add oil (about 1 quart / 1.0 liter). After adding oil, make sure that the oil level is about in the middle of the (B) range.

WARNING
Engine oil can ignite when it touches hot engine parts. This can cause fires, burns, and other severe injuries.
x Never spill oil on the engine. Oil spilled on a cold engine can also cause a fire when the engine warms up.
x Always make certain that you screw the cap of the engine oil filler opening back on tightly after adding oil and that the dipstick has been pushed all the way back into the in the guide tube. This helps prevent engine oil from leaking onto the hot engine when the engine is running.
NOTICE
x Do not start the engine if the engine oil level is above range (B). Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Otherwise the catalytic converter and engine can be damaged!

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 capacitive passenger detection system 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.
