2010 VOLKSWAGEN CC check engine

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
Starting fluids can explode and cause a run-away vehicle condi-
tion.
Never use starting assist fluids.
NOTICE
Never use fuel with an octane rating lower than 87 AKI /
91 RON. Using lower octane fuel may cause expensive engine
damage.
Never use leaded gasoline! Leaded gasoline will severely
damage your vehicle's catalytic converter.
Methanol-blended fuels that do not meet the criteria listed
above may cause corrosion and may damage plastic and rubber
parts in the fuel system.
Never use fuels that contain lead or other metals (check listing
on the fuel pump). Even lead replacement gasoline (LRP fuels)
contain metallic additives in high concentrations. They can
damage the engine.
Do not use fuels that fail to meet the criteria above, or with
contents that cannot be identified.
If you cannot tell whether a particular fuel blend meets the cri-
teria above, ask your service station or its fuel supplier. If you
notice a loss of fuel economy or drivability and performance
problems using one of these fuel blends, we recommend that
you switch to unblended fuel.
Using fuels that are different from those specified above can
damage your vehicle's engine and fuel system and cause per-
formance problems.
Damage to the engine and fuel system and performance prob-
lems caused by using fuels that are different from those speci-
fied above or by using “starting assist fluids” are not the re-
sponsibility of Volkswagen and are not covered under the Emis-
sion warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the
catalytic converter and degrade its effectiveness in reducing polluting
emissions.

WARNING
Moving parts in the engine compartment can cause serious
personal injury on contact.
Never reach into the area around or touch the radiator fan.
Contact with the blades can cause serious personal injury. Al-
ways remember that the radiator fan is temperature-controlled
and can come on suddenly even when the engine has been
switched off for a while and the key has been removed from the
ignition.
If you have to perform a check or repair when the engine is
running, there are more risks from the rotating parts, such as
the drive belts, alternator, radiator fan, etc., and from the high-
voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair
do not get caught in rotating engine parts. Before starting
any work remove your jewelry, take off your necktie, tie back
and cover your hair, and do not wear clothing that can hang
down and get caught in moving engine parts.
– Always use extreme caution if the accelerator pedal has to
be depressed to perform a check. The vehicle will start to
move even if the electronic parking brake is on.
Never leave any objects in the engine compartment, for ex-
ample cleaning rags and tools. Objects left behind can cause
malfunctions, engine damage, and even fires.

WARNING
Operating fluids and some materials in the engine compartment
can catch fire easily, causing burns and other serious personal
injuries!
Never smoke near the engine compartment.
Never work next to open flames or sparks.
Never pour or spill operating fluids or other flammable liq-
uids on the engine. These fluids can ignite on hot engine parts
and cause injuries.
If work on the fuel system or the electrical system is neces-
sary:
– Always disconnect the 12 Volt vehicle battery. Make sure
the vehicle is unlocked when you disconnect the battery, or
the alarm will go off. Never touch the electrical wiring of the
ignition system.
– Never work near heaters, water heaters, or other open
flames.
Always have a functional, approved fire extinguisher nearby.
NOTICE
When changing or topping off fluids, make sure that you pour
the fluids into the correct reservoirs. Adding the wrong type of
operating fluids will cause serious malfunctions and engine
damage.
Fluid leaks and spills are harmful to the environment. Regularly
check the ground underneath your vehicle for this reason. If you find
spots of oil or other fluids, have your vehicle checked by your author-
ized Volkswagen dealer or authorized Volkswagen Service Facility.
Dispose of leaked operating fluids properly.

WARNING
Disregarding the safety-related checklist may result in serious
injuries.
Always review and follow the checklist. Follow accepted safe-
ty practices and use common sense.
Opening or closing the engine compartment

Fig. 163 In the footwell on the driver side: Inside engine hood release
lever.

WARNING
If the hood is not closed properly, it could fly up and block your
view while you are driving. This can lead to a crash and serious
personal injuries.
After closing the engine hood, check that the hood release
lever is properly latched into the hood latch. The engine hood
must be flush with the surrounding auto body parts.
If you ever notice that the hood latch is not properly secured
when the vehicle is moving, stop at once and close it.
Never let anyone get in the way of the hood when closing it.
NOTICE
Make sure the windshield wipers are switched off and the
windshield wiper arms are resting on the windshield before you
open the hood. Otherwise, the windshield wipers and the hood
may be damaged.
Always put the windshield wiper arms down against the wind-
shield before driving the vehicle.
NOTICE
Before opening or closing the engine hood, make sure there is
enough room to do so, for example when the vehicle is in a gar-
age.

Checking the engine oil level and adding oil

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.
