For vehicles with the 3.6 liter engine, the engine oil temperature can
be displayed in the Volkswagen Information System MFI menu ⇒  MFI
menu (Multi-Function Indicator).
WARNING
Failure to heed warning lights and instrument cluster text mes-
sages can cause the vehicle to break down in traffic and result
in a collision and serious personal injury.
Never ignore warning lights or text WARNINGS.
Always stop the vehicle as soon as it is safe to do so.
NOTICE
Failure to heed warning lights or text WARNINGS can result in

WARNING
Engine coolant is poisonous!
Always keep the coolant in its original container stored in a
safe place.
To reduce the risk of poisoning, never store engine coolant in
empty food or beverage containers or in any other containers
that might mislead someone into drinking from them.
Always keep engine coolant out of reach of children.
Always make sure there is enough of the correct coolant ad-
ditive to provide proper antifreeze protection at the coldest
temperatures that can be expected where the vehicle will be
used.
At extremely cold temperatures, the coolant could freeze,
causing the vehicle to break down. The heater would also not
work, and vehicle occupants could be without protection at
subfreezing temperatures.
Coolant and coolant additives can pollute the environment. Col-
lect leaking operating fluids and dispose of them properly in accord-
ance with applicable environmental laws and regulations.
Warning light and engine coolant temperature gauge

Fig. 167 Engine coolant temperature gauge in the instrument cluster:
A Engine cold; B Normal temperature range; C Warning zone.

If the indicator in the engine coolant temperature gauge is located in
the cold range (A), the engine has not reached operating tempera-
ture. High engine speeds and heavy engine loads should be avoided.
Under normal driving conditions, the needle should be in the middle
of the gauge. The temperature may go higher when the engine is
working hard, especially in hot weather.
When the ignition is switched on, several warning and indicator lights
come on briefly for a function check. They go out after a few seconds.
The following table explains what to do if the engine coolant tempera-
ture warning light ~ does not go out a few seconds after the engine
is started or starts flashing while driving.

Engine coolant specifications

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.
