climate control VOLKSWAGEN CC 2010 Owners Manual

WARNING
Driving with an open luggage compartment lid can cause poi-
sonous carbon monoxide in the engine exhaust to get into the
passenger compartment.
Carbon monoxide causes drowsiness, inattentiveness, poi-
soning, and loss of consciousness. It can lead to accidents and
severe personal injuries.
Always keep the luggage compartment lid closed while driv-
ing to help keep poisonous exhaust fumes from being drawn
into the vehicle.
Never transport objects that are too large to fit completely
into the luggage area, because then the luggage compartment
lid cannot be fully closed.
If you absolutely must drive with an open luggage compart-
ment lid, do the following to reduce the risk of carbon monox-
ide poisoning:
– Close all windows and the power sunroof.
– Switch off the climate control system's air recirculation fea-
ture.
– Open all air vents in the instrument panel.
– Set the fresh air fan to the highest speed.
NOTICE
The open luggage compartment lid changes the vehicle height.
Driving a loaded vehicle

Treadwear
The treadwear grade is a comparative rating based on the wear rate
of the tire when tested under controlled conditions on a specified
government test course.
For example, a tire graded 150 (Treadwear-value 150) would wear
one-and-one-half (1 1/2) times as well on the government course as a
tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may depart significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire's ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor
traction performance ⇒ .
Temperature
The temperature grades are A (the highest), B, and C representing
the tire's resistance to the generation of heat, and its ability to dissi-
pate heat when tested under controlled conditions on a specified in-
door laboratory test wheel.
Sustained high temperature can cause the material of the tire to de-
generate and reduce tire life, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to a level of performance which all passen-
ger car tires must meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent higher levels of perfor-
mance on the laboratory test wheel than the minimum required by law
⇒ .
WARNING
The traction grade assigned to this tire is based on straight-
ahead braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.

Vehicles with gear recommendation aid in fuel efficient driving by in-
dicating the optimum time to shift gears.
Coasting
If you take your foot off the accelerator, fuel delivery to the engine is
interrupted, which lowers fuel consumption.
Therefore, when nearing a red stop light, for instance, allow the vehi-
cle to coast without using the accelerator. Press the clutch pedal and
release it only if the vehicle moving too slowly or the coasting dis-
tance is too long. The engine will then continue to run at idle.
In situations where the vehicle will be stopped for a longer period of
time, such as at a railroad crossing, physically switch off the engine.
Defensive driving and “flowing” with traffic
Frequent braking and acceleration increase fuel consumption signifi-
cantly. Just by driving defensively and keeping a sufficiently large
distance away from the vehicle in front of you can make up for the
speed fluctuations caused by taking your foot off the accelerator. Ac-
tive braking and accelerating is then not necessarily required.
Calm and smooth driving
Consistency is more important than speed. The more smoothly you
drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed
is more efficient and economical than constantly accelerating and
braking. Usually you can reach your destination just as quickly by
driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving
style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to
use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (exam-
ples):
Climate control system (air conditioner): If the air conditioner has to
produce starkly contrasting temperatures, it requires a large amount
of energy, which is generated by the engine. The temperature in the
vehicle should therefore not be extremely different from that of the

WARNING
Poor visibility increases the risk of collisions and other acci-
dents that cause serious personal injuries.
Always make sure all windows are clear of ice, snow and
condensation for good visibility to the front, sides, and rear.
Maximum heating output and defrosting performance are not
possible until the engine has reached operating temperature.
Wait until you have good visibility before driving off.
Always make sure you know how to properly use the climate
control system as well as the rear window defroster that you
will need for good visibility.
Never use air recirculation for long periods of time. When the
air conditioner is off and recirculation mode is on, condensa-
tion can quickly form on the windows and greatly reduce visi-
bility.
Always switch off recirculation mode when it is not needed.
WARNING
Stale air causes driver fatigue and reduces driver alertness,
which can cause accidents, collisions and serious personal in-
jury.
Never switch off the fan for a long period of time and never
use air recirculation for a long period of time because no fresh
air will enter the passenger compartment.
NOTICE
If you think the air conditioner is not working properly or may
be damaged, switch it off to help prevent more damage. Have the
air conditioner checked by an authorized Volkswagen dealer or
an authorized Volkswagen Service Facility.
Air conditioner repair requires specialized knowledge and
special tools. Volkswagen recommends that you see an author-
ized Volkswagen dealer or an authorized Volkswagen Service
Facility.
Do not smoke when air recirculation is switched on. Smoke
drawn into the ventilation system can leave residue on the evap-

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.
