coolant temperature VOLKSWAGEN CC 2010 Owners 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
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.

Check the engine coolant

If the engine coolant level
is correct or the problem
continues after adding
coolant, do not drive any
farther. Contact an au-
thorized Volkswagen deal-
er or authorized
Volkswagen Service Facili-
ty.
These instructions apply
only when the coolant
temperature stays in the
normal range. Stop imme-
diately if the needle goes

malfunction.

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.

WARNING
Improper use of operating fluids and equipment can cause ac-
cidents, serious personal injuries, burns and/or poisoning.
Always store vehicle care products in a safe place in original
containers that are securely closed.
To reduce the risk of poisoning, never use empty food or
beverage containers that might mislead someone into drinking
from them.
Always keep vehicle care products out of the reach of chil-
dren.
Always read and heed all the instructions and all WARNINGS
on the package before using vehicle care products.
When using products that give off harmful fumes, always
work outdoors or in a well ventilated area.
Never use fuel, turpentine, engine oil, nail polish remover or
other volatile fluids for vehicle care. They are poisonous and
highly flammable. They could cause fires and explosions!
NOTICE
Only refill with suitable operating fluids. When changing or
topping off fluids, make sure that you pour the fluids into the
correct reservoirs. Adding incorrect fluids will cause serious
malfunctions and engine damage! Under no circumstances
should you mix up operating fluids. Otherwise serious malfunc-
tions and engine damage can occur!
Accessories and other things installed in front of the cooling
air intakes impair the efficiency of the engine coolant. The en-
gine can overheat under high outside temperatures or under
high engine loads!
Leaking operating fluids can pollute the environment. Collect
leaking operating fluids in suitable containers and dispose of them
properly in accordance with applicable environmental laws and regu-
lations.
