WARNING
Working on the batteries or the electrical system in your vehicle can cause serious acid
burns, fires, explosions, or electrical shocks. Always read and heed the following WARNINGS
and safety precautions before working on the batteries or the electrical system.
x Before working on the electrical system, always switch off the ignition and all electrical
consumers and disconnect the negative (-) cable from the standard 12 Volt battery.
x When you change a light bulb, always switch off the light first.
x Always keep children away from battery acid and vehicle batteries in general.
x Always wear eye protection. Never let battery acid or lead particles come into contact with
your eyes, skin, or clothing.
x Sulfuric battery acid is very corrosive. It can burn unprotected skin and cause blindness.
Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the
batteries, as this could spill acid through the vents and burn you.
x If you get battery acid in your eyes or on your skin, immediately rinse with cold water for
several minutes and then get immediate medical attention. If you swallow any battery acid,
get medical attention immediately.
x When disconnecting the batteries from the vehicle electrical system, always disconnect
the negative cable (-) first and then the positive cable (+).
x Always switch off all electrical consumers before reconnecting 12 Volt batteries.
Reconnect the plus cable (+) first and then the negative cable (-). Never reverse the polarity of
the connections. This could cause a fire.
x A highly explosive mixture of gases is given off when the battery is being charged.
x Do not smoke and avoid fires, sparks, and open flames when working. Never create
sparks or electrostatic charges when handling cables and electrical equipment. Never short
circuit the battery terminals. High-energy sparks can cause serious personal injury.
x Never use or attempt to charge a damaged or frozen battery, or a battery that was frozen
but has thawed. Charging a frozen or thawed battery could cause explosions and chemical
burns! Replace damaged or frozen vehicle batteries immediately. A dead battery can freeze at
temperatures around +32 °F (0 °C).
x If the battery has a vent line or tube, make sure that it is properly connected to the battery.
x Always make sure that the vent line is securely attached to a vehicle battery that is located
in the luggage compartment.
WARNING
California Proposition 65 Warning
x Battery posts, terminals, and related accessories contain lead and lead components,
chemicals known to the State of California to cause cancer and reproductive harm. Wash
your hands after handling.
NOTICE
x Do not expose the vehicle battery to direct sunlight for an extended period of time as
ultraviolet rays may damage the battery housing.
x If the vehicle is left standing in the cold for a long time, protect the vehicle battery from
freezing. A battery will be permanently damaged by freezing.

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.
x After installing the compact spare wheel, check the tire pressure as soon as possible.
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. 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.
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 come on
after a couple of minutes.
If possible, attach the compact spare wheel or the tire you took off the vehicle securely in the
luggage compartment.

WARNING
A loose fire extinguisher in the passenger can be thrown around the passenger compartment
and cause serious personal injury during hard braking, an emergency maneuver or during a
crash
x Always make sure that the fire extinguisher is properly and firmly secured in bracket
provided.

WARNING
Improper replacement of burned out headlights and other light bulbs can cause serious
personal injury.
x Stop! Always read and heed the WARNINGS before doing any work in the engine
compartment. The engine compartment of any motor vehicle is a potentially dangerous area,
and work in this area can lead to serious personal injury.
x HID – High Intensity Discharge (Xenon) headlights get power from a high voltage source
that can cause severe personal injury and even death if handled improperly.
x H7 bulbs and HID – High Intensity Discharge (Xenon) headlights are under high pressure
and can explode if handled improperly.
x Always let a burned out light bulb cool down before replacing it.
x Never replace a light bulb unless you are familiar with all of the necessary procedures. In
particular, never remove a headlight unless you know exactly how to carry out the job and
have the correct tools and light bulbs.
x If you are uncertain about what to do, have the work performed by an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified
workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon)
headlights and H7 bulbs replaced by a qualified technician.
x Do not touch the glass of light bulbs with your bare hands. Fingerprints left on the bulb
evaporate due to the heat when the bulb is switched on and cause the reflector to “cloud.”
x There are sharp edges on and around the headlight housing in the engine compartment
and the rear light housing. Wear hand protection if you replace bulbs.
NOTICE
After replacing a headlight bulb or other light bulb, always make sure that the rubber covers or
plastic caps have been properly and securely reinstalled to help prevent water from getting
into the electrical connections and headlight housing and damaging the electrical system.
