WARNING
Hot steam and hot engine coolant can cause serious burns.
Never open the hood if you see steam or coolant escaping
from the engine compartment. Always wait until you no longer
see or hear steam or coolant escaping from the engine.
Always let the engine cool down completely before carefully
opening the hood. Hot components will burn skin on contact.
When the engine has cooled down and you are ready to open
the hood:
– Apply the electronic parking brake and shift the transmis-
sion into Park (P) (automatic) or Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the re-
mote control vehicle key is out of range of the vehicle and
that the vehicle cannot be started by depressing the starter
button
– Always keep children and others away from the engine
compartment and never leave them unsupervised.
The engine coolant system is under pressure when the en-
gine is hot. Never unscrew the coolant expansion tank cap
when the engine is hot. Hot coolant can spray out and cause
severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclock-
wise direction while applying light downward pressure on the
top of the cap.
– Always protect your face, hands, and arms from hot escap-
ing coolant or steam by covering the cap with a large, thick
rag.
Never spill fluids on the engine or exhaust system when re-
filling. Spilling fluids onto hot parts of the engine or exhaust
system can cause a fire. Under some conditions, the ethylene
glycol in engine coolant can catch fire.
NOTICE
Use distilled water only when adding coolant! All other types
of water contain chemical compounds that can cause extensive
corrosion damage to the engine. This can even lead to engine

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 elec-
trical system.
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.
When you change a light bulb, always switch off the light
first.
Always keep children away from battery acid and vehicle bat-
teries in general.
Always wear eye protection. Never let battery acid or lead
particles come into contact with your eyes, skin, or clothing.
Sulfuric battery acid is very corrosive. It can burn unprotect-
ed 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.
If you get battery acid in your eyes or on your skin, immedi-
ately rinse with cold water for several minutes and then get
immediate medical attention. If you swallow any battery acid,
get medical attention immediately.
When disconnecting the batteries from the vehicle electrical
system, always disconnect the negative cable (-) first and then
the positive cable (+).
Always switch off all electrical consumers before reconnect-
ing 12 Volt batteries. Reconnect the plus cable (+) first and then
the negative cable (-). Never reverse the polarity of the connec-
tions. This could cause a fire.
A highly explosive mixture of gases is given off when the bat-
tery is being charged.
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.

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).
If the battery has a vent line or tube, make sure that it is
properly connected to the battery.
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
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
Do not expose the vehicle battery to direct sunlight for an ex-
tended period of time as ultraviolet rays may damage the battery
housing.
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.
Undeployed battery isolator modules are classified as Perchlo-
rate Material. Special handling may apply – see
http://www.dtsc.ca.gov/hazardouswaste/perchlorate. Obey all appli-
cable legal requirements regarding handling and disposal of the vehi-
cle or parts of its restraint system, including airbag modules and safe-
ty belts with pretensioners. Authorized Volkswagen dealers and au-
thorized Volkswagen Service Facilities are familiar with the require-
ments, and we recommend that you have them perform this service
for you.
Emergency starting and starting the engine with a very weak ve-
hicle battery or after the vehicle battery has been replaced may

change or delete system settings (including time, date, personal con-
venience settings, and programming). Check the settings and correct
as necessary once the vehicle battery has built up a sufficient charge.
Warning light

Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent onboard electrical
system management automatically takes steps to help prevent bat-
tery drain.
The idle speed is increased so that the alternator provides more
power.
The power to devices that consume a lot of electricity is cut back or
switched off completely.
When the engine is started, the power supply to the 12 Volt sockets
is temporarily interrupted.
The onboard electrical system management cannot always keep the
battery from being drained. For example, the battery will drain if the
engine is not running, but the ignition is switched on or the parking
lights are left on for a long time when parked.
Battery disconnection in an accident with airbag deployment
In vehicles with a battery in the luggage compartment, the electrical
connection to the battery is disconnected automatically in a collision
with airbag deployment. This helps to prevent a short-circuit.
What drains the vehicle battery?
Long periods when the engine is not running, especially when the
ignition is on.
Using electrical systems or devices when the engine is switched
off.
Leaving the vehicle unlocked for several days when not in use.
The selector lever is left for a long period of time in any position
other than P when the ignition is switched off ⇒  Automatic transmis-
sion: Selector lever.
WARNING
Failure to use the proper battery with proper mounting and
connections may cause short circuits, fires, and serious per-
sonal injuries.
Always use only maintenance-free or cycle-free, leak-proof
batteries with the same specifications and dimensions as the
original equipment battery. Specifications are listed on the bat-
tery housing.

Rinse the sponge or glove thoroughly and often.
Clean the wheels and under the door sills last. Use a different sponge
or wash mitt.
WARNING
After the vehicle has been washed, the wet brakes or, in winter,
brake discs or pads coated with ice, react slower and need
longer stopping distances.
Always dry the brakes and clean off any ice coatings with a
few careful applications of the brake. Make sure not to endan-
ger other motorists or cyclists or disobey legal requirements.
CAUTION
Sharp edges under the vehicle can cut exposed skin.
Always protect your hands and arms from cuts on sharp
metal edges when cleaning the underbody, the inside of the
wheel housings, etc.
NOTICE
The water temperature must not be more than +140 °F
(+60 °C).
To help prevent damage to the paint, do not wash the vehicle
in direct sunlight.
Do not use insect sponges, abrasive kitchen sponges or simi-
lar things to clean the vehicle. These can damage the paint fin-
ish.
Never clean headlights with a dry cloth or sponge. Always use
a wet cloth or sponge. For best results use soapy water.
When washing or rinsing the vehicle in cold weather, do not
let water get into the lock cylinders or point the hose at gaps
around the doors, hood, or luggage compartment lid. The water
could freeze on the locks and seals and make it difficult to open
the vehicle!

WARNING
Improper use of power washers can cause serious invisible
permanent damage leading to tire failure and loss of vehicle
control. This can cause accidents and severe personal injury.
Keep sufficient distance between water jet and tires. Never
wash tires with a nozzle that sprays the water out in a direct
stream regardless of the distance to the tire and even for a very
short time.
Never use “dirt blasters” to clean tires. Even spraying from a
relatively long distance for a very short time can do visible or
invisible damage to tires.

Cleaning upholstery on non-heated seats, manual seats, or seats
without airbag components
Before using any cleaning agent, familiarize yourself with instruc-
tions and warnings on the packaging.
Vacuum upholstery, fabric trim, Alcantara® upholstery, and carpet-
ing regularly with a suitable brush attachment.
Do not use power washers, steam cleaners, or cooling spray.
A soft sponge or a commercially available lint-free microfiber cloth
may be used for general cleaning ⇒ .
Clean Alcantara® surfaces with a damp cotton or wool cloth or a
commercially available lint-free microfiber cloth ⇒ .
Upholstery and fabric trim with light generalized soiling can be
cleaned with a commercially available dry-foam cleaner.
If the upholstery and fabric trim pieces are heavily soiled, see your
authorized Volkswagen dealer or authorized Volkswagen Service
Facility before you begin cleaning to learn about suitable cleaning
options. If necessary, have the cleaning done by a professional.
Treating stains
When treating stains, it may be necessary to clean the entire surface
and not just the stain itself. This is especially true if the entire surface
has become dirty from normal use. Otherwise, the area that is treated
may become lighter than the untreated area. If you have questions or
concerns, consult a professional cleaner.

Type of stain Recommended cleaning for fabric and uphol-
stery
Water-based
stains, such as
coffee or fruit
juice.
– Moisten a sponge with water and rub the stain
gently with a circular motion.
– Wipe dry with an absorbent cloth.
Persistent stains,
such as choco-
late or make-up.
– Use only Volkswagen-approved cleaning prod-
ucts.
– If necessary, have the fabric or upholstery pro-
fessionally cleaned.

Screw in the wheel bolts clockwise and tighten them slightly using
the hexagonal socket in the screwdriver handle.

⇒ . Do not tighten them in sequence! Tighten any wheel bolt to
begin, then tighten the wheel bolt diagonally opposite the first bolt,
and so forth.
Install the wheel bolt caps, center wheel hubcap, or wheel cover, if
any ⇒  Wheel trim.
WARNING
Wheel bolts that are tightened or installed improperly can come
loose, causing loss of vehicle control, a crash, and serious per-
sonal injury.
Always keep wheel bolts and threads in the wheel hub clean
and free of oil and grease. The wheel bolts must turn easily and
must be tightened with the right torque.
Use the hexagonal socket in the screwdriver handle only to
turn the wheel bolts when they are loose, never to loosen them
or tighten them firmly.
WARNING
Improper use of a compact spare wheel can cause loss of vehi-
cle control, a crash or other accident, and serious personal in-
jury.
Never use a compact spare wheel if it is damaged or worn
down to the wear indicators.

spare wheel. Avoid full-throttle acceleration, heavy braking, and
fast cornering!
Never drive more than 125 miles (200 km) with a compact
spare wheel that is installed on the front axle (drive axle).
Replace the compact spare with a normal wheel and tire as
soon as possible. Compact spare tires are designed for brief
use only.

WARNING
Using the wrong fuse, using a blown fuse that has been re-
paired, and using metal objects in place of fuses to complete
the electrical connection in the circuit can cause fires and seri-
ous personal injury.
Never replace a fuse with one that has a higher amp rating.
Replace a blown fuse only with a fuse of the same amperage
(same color and same imprint) and same overall size.
Never repair fuses.
Never replace fuses with a metal strip, a paper clip, or a simi-
lar object.
NOTICE
To help prevent damage to the electrical system, switch off all
lights and accessories, switch off the ignition, and remove the
key from the ignition switch before replacing a fuse.
If a fuse is replaced with a fuse with higher amperage, this can
also cause damage at different locations in the electrical system.
Open fuse boxes must be protected from dirt and moisture.
Dirt and moisture in fuse boxes can cause damage to the electri-
cal system.
