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 de-signed 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 per-missible 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.

WARNING
Improper or incorrect connections to the vehicle electrical system can cause malfunctions that affect the entire vehicle electrical system and cause accidents and serious personal injury.
x Never connect the electrical system of the trailer directly to the electrical connections of the rear lights or other unsuitable power sources. Use only a suitable connector to provide power to the trailer.
x Have any trailer hitch retrofit or other work on a trailer hitch done by a qualified workshop.
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.

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 guaran-tee 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.
Vehicle capacity weight
The total rated cargo, luggage and passenger load. Passenger load is 150 lbs (68 kilograms) times the vehicle's total seating capacity (as listed on the label inside the driver door).

Tires and vehicle load limits

Page 184 of 412


WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or other accident, serious personal injury, and even death.
x Carrying more weight than your vehicle was designed to carry will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
x The brakes on a vehicle that has been overloaded may not be able to stop the vehicle in a safe distance.
x Tires on a vehicle that has been overloaded can fail suddenly, including a blowout and sudden deflation, causing loss of control and a crash.
x Always make sure that the total load being transported – including the weight of a trailer hitch and the tongue weight of a loaded trailer – does not make the vehicle heavier than the vehicle's Gross Vehicle Weight Rating.
Determining the correct load limit

Adjust the tire pressure
The proper tire pressure helps reduce rolling resistance as well as fuel consumption.
When purchasing new tires, always make sure that the tires are optimized for lower rolling resistance.
Use low viscosity engine oil
Fully “synthetic,” low viscosity engine oils that expressly comply with Volkswagen oil quality standards reduce fuel consumption. Low viscosity engine oils reduce the frictional resistance on the engine and are distributed more evenly and quickly, particularly when cold-starting the engine. The effect is partic-ularly apparent in vehicles that frequently travel short distances.
Always ensure the right engine oil level is maintained and keep to the scheduled service intervals (engine oil changes).
Make sure the engine oil that you purchase expressly complies with Volkswagen oil quality standards and is the oil approved by Volkswagen for your vehicle.
Avoid unnecessary weight
The lighter the vehicle, the more economical and eco-friendly it will be. For example, an extra 220 lbs (100 kg) of weight increases fuel consumption by up to 1 pint per 60 miles (0.3 l/100 km).
Remove all unnecessary items and unnecessary dead weight from the vehicle.
Remove unnecessary aftermarket components
The more aerodynamic the vehicle, the less fuel it will consume. Aftermarket components such as bicycle racks reduce its aerodynamic performance.
Therefore, remove unnecessary structures and unused rack systems, particularly if planning to drive at higher speeds.

WARNING
Improperly lifting your vehicle with a workshop hoist or a floor jack can cause the vehicle to fall off and cause serious personal injury.
x Always read and heed the operating instructions from the floor jack manufacturer and legal regulations if necessary before using the floor jack to lift the vehicle.
x Never let anyone stay in the vehicle when it is being lifted or when it is off the ground.
x Always lift your vehicle only at the designated lift points shown in the illustrations
⇒ fig. 172 and ⇒ fig. 173. Not using the designated lift points can cause the vehicle to fall off the floor jack when heavy parts such as the engine or transmission are removed.
x Always make sure that the vehicle's lift points lie as flat as possible and centered on the carrier plates of the floor jack.
x Never start the engine when you have raised the vehicle on the floor jack. The engine vibrations and vehicle movements could knock the vehicle off the floor jack.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle is safely supported on safety stands intended for that purpose that are strong enough to support the weight of the vehicle.
x Never use the floor jack as a ladder or step ladder.
x Always make sure that the weight of the vehicle is not heavier than the lifting capacity of the floor jack and safety stands being used.
NOTICE
x To help prevent serious vehicle damage, never lift the vehicle by the engine oil pan, trans-mission housing, or by the front or rear axles or suspension.
x To help prevent damage to the underbody or chassis, always insert a rubber pad between the hoist and the lifting points. In addition make sure the lifting arms have enough clearance.
x The lifting arms should not touch side sills or other parts of the vehicle.
