Tie-downs

Fig. 96 In the luggage compartment: Tie-downs.

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 inju-ries 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 sudden-ly and change the vehicle's handling.
x Secure even small and light objects. Loose objects in the luggage or passenger compart-ment can fly about during sudden braking maneuvers or in the event of an accident and in-jure occupants.
x Never exceed the maximum allowable load on the tie-downs when securing objects.
x Never secure a child restraint 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 lug-gage compartment and then to the tie-downs near the loading edge of the luggage compart-ment. 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 380 lbs. (172 kg).
For suitable straps and luggage stowage systems, please see an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING
Installing or using a base carrier or roof rack improperly can cause the entire system to fly off the vehicle, causing accidents and injuries.
x Always follow the installation instructions provided by the manufacturer.
x Use the base carrier and roof rack only if they are undamaged and properly installed.
x Secure the roof rack base carrier only at the attachment points shown in the illustration
⇒ fig. 97.
x Always install the base carrier and roof rack properly.
x Make sure that all bolts and fasteners are properly installed and properly tightened before every trip and retighten them as needed after driving a short distance. During a long trip, check all bolts and fasteners at each stop.
x Always properly install special fixtures for items such as bicycles, skis, surfboards, etc.
x Do not modify or repair the base carrier or roof rack.
Follow the installation instructions provided for installing the roof rack system. Always carry them in the vehicle.
Securing a load on the roof rack

WARNING
If the maximum permissible roof load is exceeded, accidents and substantial vehicle damage may occur.
x Never exceed the specified roof load, the maximum Gross Axle Weight Rating, or the Gross Vehicle Weight Rating.
x Do not exceed the loading capacity of the roof rack, even if the permissible roof load is not fully utilized.
x Always make sure that loads are evenly distributed and that heavier items are, as far as possible, toward the front.
WARNING
Loose or improperly secured items can fall off the roof rack and cause accidents and injuries.
x Always use suitable, undamaged tie-down ropes and ratchet straps.
x Secure the load properly.

WARNING
Improper use of the trailer hitch can cause accidents and injuries. An improperly installed, incorrect, or damaged trailer hitch can cause the trailer to separate from the towing vehicle and cause serious personal injuries.
x Only use an undamaged, properly mounted trailer hitch.
x Never repair or modify the trailer hitch.
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 mount when you are not towing a trailer.
x Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The vehicle was not designed for these kinds of trailer hitches. The trailer hitch attachment can fail, causing the trailer to tear loose from the vehicle.
WARNING
Improper trailer towing can cause loss of vehicle control and serious personal injury.
x Driving with a trailer and carrying heavy or large things can change the way the vehicle handles, increase the distance it needs to stop safely, and cause accidents.
x Always secure the load properly with suitable and undamaged straps so that the load will not shift.
x Always adapt your speed and driving to the heavier load and the weight distribution in the vehicle. Take road, weather, traffic, and visibility conditions into account as well.
x Reduce your speed even more than you otherwise would when going downhill and under unfavorable load, weather, or wind conditions.
x Trailers with a high center of gravity tip more easily than trailers with a low center of gravi-ty.
x Always avoid sudden maneuvers and hard braking.
x Be especially careful when passing other vehicles.
x Reduce speed immediately if the trailer shows the slightest sign of swaying.
x Never try to stop the swaying by accelerating.
x Always obey speed limits. In some areas, the speed limits for vehicles towing trailers are lower than for vehicles without trailers. Never drive faster than 50 mph (80 km/h; under ex-ceptional circumstances, 60 mph - 100 km/h) when towing a trailer. This applies even if the local speed limit is higher.
If you are driving a new vehicle or a vehicle with a new or rebuilt engine, do not tow a trailer
during the break-in period, about 600 miles (1000 km) ⇒  Parts, accessories, repairs, and modifica-tions.
If you tow a trailer, your vehicle may need maintenance more often because of the extra load it has to move.
When you are not towing, remove the trailer hitch ball. This helps keep the trailer hitch from causing damage to your vehicle and to others if your vehicle is hit from behind.
Some models need a trailer hitch to tow or tow-start other vehicles. You may want to always carry the ball mount in the vehicle after it has been removed. Be sure to stow it securely.

WARNING
Exceeding the gross weight ratings for axle, tongue, vehicle, trailer or combined weight can cause accidents and serious personal injury.
x Never exceed the specified values.
x Never let the actual weights at the front and rear axles exceed the Gross Axle Weight Rat-ing. Never let the combined front and rear weights exceed the Gross Vehicle Weight Rating.
WARNING
Trailer loads that are not properly secured can shift when the vehicle is moving or braking and suddenly change the way the vehicle handles, causing accidents and severe injuries.
x Always load the trailer properly.
x Always secure the load properly with suitable, undamaged straps that can be tightened so that the load cannot shift.
Driving with a trailer

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.

The design of the wheel bolts is matched to the factory-installed wheels. If different wheels are in-stalled, 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 author-ized 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

Stowing the replaced wheel
x Open the luggage compartment lid, lift up the floor covering, and remove it from the luggage com-partment.
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 clockwise until the wheel is securely in place.
x If necessary, return the vehicle tool kit to its location in the luggage compartment.
x Return the floor covering to the luggage compartment floor.
x Close the luggage compartment lid.
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.
Differences between the road tires and the compact spare
The compact spare is different in design from the road tires and 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 compact spare wheel, check the tire pressure as soon as possible ⇒  Tire infla-tion 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 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 compact spare wheel can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a compact spare wheel if it is damaged or worn down to the wear indicators.
x In some vehicles, the 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 spe-cial 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 compact spare is being used, the TPMS indicator light can come on after a couple of
minutes ⇒  Tire Pressure Monitoring System (TPMS).
If possible, attach the compact spare wheel or the wheel you took off the vehicle securely in the luggage compartment.
