engine coolant VOLKSWAGEN CC 2015 Owner´s Manual

Air conditioner does not work
The air conditioner may not switch on for one of the following rea-
sons:
The engine is not running.
The fan is switched off.
The air conditioner fuse has blown.
The outside air temperature is colder than about +38 °F (+3 °C).
The air conditioner compressor has been temporarily switched off
due to excessive engine coolant temperature.
There is another malfunction in the vehicle. Have the air condition-
er checked by an authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
Special considerations
When it is very hot and humid outside, water condensation can drip
from the air conditioner evaporator and form a puddle under the vehi-
cle. This is normal and does not indicate a leak.
The climate control system adjusts the passenger compartment
temperature as fast as possible considering the outside temperature.
Due to residual moisture in the air conditioner, the windshield
may fog up after the engine is started. Switch on the windshield de-
froster to help evaporate the condensation as quickly as possible.
The air coming out of the vents flows through the passenger
compartment and through the vents under the rear window. Do not
cover these slots with clothing or other things.

WARNING
The engine compartment of any motor vehicle is a potentially
dangerous area and can cause serious personal injury.
Always use extreme caution when doing any work in the en-
gine compartment. Always follow commonly accepted safety
practices and use common sense. Never risk personal injury.
Never perform any work in the engine compartment unless
you know exactly how to carry out the job and have the correct
technical information and the correct tools.
If you are uncertain about what to do, have the work per-
formed by an authorized Volkswagen dealer, an authorized
Volkswagen Service Facility, or another qualified workshop.
Serious personal injury may result from improperly performed
work.
We strongly recommend that you always have HID – High In-
tensity Discharge (Xenon) headlights and H7 bulbs replaced by
a qualified technician. Serious personal injury may result from
improperly performed work.
Never open or close the engine hood if steam or coolant is
escaping. Hot steam or coolant can cause serious burns. Al-
ways wait until you no longer see or hear steam or coolant es-
caping from the engine.
Always let the engine cool down completely before carefully
opening the hood.
Hot parts of the engine and the exhaust system will burn skin
on contact.
When the engine has cooled down and you are ready to open
the hood:
– Firmly apply the parking brake and shift the transmission
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 ⇒  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.
WARNING
High voltage systems in the engine compartment can cause
electrical shocks or even electrocution, severe burns, other se-
rious injuries, and even death!
Never short-circuit the electrical system. Be especially care-
ful when using jumper cables. The vehicle's battery could ex-
plode!
To reduce the risk of electrical shock and personal injury
while the engine is running or being started:
– Never touch ignition cables. Never touch other compo-
nents of the high voltage electronic ignition system.
– Never touch the wiring of the HID – High Intensity Dis-
charge (Xenon) headlights.
Read and heed the important information and warnings on
cleaning the engine compartment ⇒  Cleaning the engine com-
partment.

Engine coolant

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.

farther. Contact an au-

ty.

come on briefly for a function check. They go out after a few seconds.
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
vehicle damage.
Engine coolant specifications

When adding engine coolant, use a mixture of distilled water and at
least 40% coolant additive G 13 or G 12 plus-plus (TL-VW 774 G) for
optimum corrosion protection ⇒ .
Do not mix G 13 with G 12 plus or G 11. Mixing these coolant addi-
tives together significantly reduces corrosion protection ⇒  and can
lead to engine damage that is not covered by any Volkswagen Lim-
ited Warranty.
WARNING
Too little antifreeze protection in the engine cooling system can
cause engine failure and severe injuries.
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.
NOTICE
Never mix original Volkswagen engine coolant additives with
other additives not approved by Volkswagen. Mixing
Volkswagen coolant additives with coolant additives made by
other manufacturers can seriously damage the engine and the
engine cooling system.
If the fluid in the engine coolant reservoir is any color but pink,
then G 13 was mixed with a different engine coolant. If this is the
case, the engine coolant must be replaced immediately. Other-
wise serious malfunctions or engine damage can occur!
Engine coolant and engine coolant additives can pollute the envi-
ronment. Collect leaking operating fluids and dispose of them proper-
ly in accordance with applicable environmental laws and regulations.
