service VOLKSWAGEN CC 2017 Service Manual

If the trailer uses too much electricity, the vehicle's electronics
may be damaged.
Never connect the electrical system for the trailer directly to
the electrical connections for the rear lights or to any other un-
suitable power sources. Use only a suitable connector to pro-
vide power to the trailer.
If you tow a trailer frequently, Volkswagen recommends having
the vehicle serviced between the regular maintenance and inspection
intervals because of the extra load it has to pull.
Hitching up and connecting a trailer

Never mount used tires on your vehicle if you are not sure of
their past use. Old, used tires and wheels may have damage
that cannot be seen that can lead to sudden tire failure and loss
of vehicle control.
Tires age even if they are not being used and can fail sudden-
ly, especially at high speeds, causing loss of vehicle control,
accidents, and severe personal injuries. Tires that are more
than 6 years old can be used only in an emergency and even
then only with special care and at low speed.
For technical reasons it is usually not possible to use wheel rims
from other vehicles. Even wheel rims from the same model may not fit
properly. Check with an authorized Volkswagen dealer or authorized
Volkswagen Service Facility if necessary.
Tire and wheel handling

Fig. 110 Tire rotation diagram.

The tires and wheels are essential parts of the vehicle's design. The
tires and wheels approved by Volkswagen are specially matched to
the characteristics of the vehicle for good road holding and safe han-
dling when in good condition and properly inflated.
Avoiding tire damage
If you must drive over a curb or other obstacle, drive very slowly
and as much as possible at a right angle to the curb with the tire tread
of both front wheels contacting the curb at the same time.
Regularly check tires for damage, such as punctures, cuts, tears
and blisters.
Remove embedded material in the tread profile that has not yet
penetrated the inside of the tire ⇒ Tire wear and damage.
Heed all warning messages from the Tire Pressure Monitoring Sys-
tem
Replace worn or damaged tires immediately ⇒  Tire wear and
damage.
Damage to tires and wheels is often not readily visible. If you notice
unusual vibration or the vehicle pulls to one side, this may indicate
that one of the tires is damaged. The tires must be checked immedi-
ately for hidden damage by an authorized Volkswagen dealer or an
authorized Volkswagen Service Facility. See also ⇒ Tire wear and
damage.
Never exceed the load and permissible maximum speed rating of
the tires ⇒ Tire labeling.
Always keep aggressive chemicals including grease, oil, gasoline
and brake fluid off the tires, including the spare wheel ⇒ .
Replace missing valve caps immediately.
Unidirectional tires
Unidirectional tires are designed to rotate only in one direction. Unidi-
rectional tires have arrows on the sidewalls that show the direction of
rotation ⇒ Tire labeling. Unidirectional tires must always be mounted
according to the specified direction of rotation in order to deliver their
best grip, braking performance, low road noise, and good wear as
well as good hydroplaning resistance.
If you have to mount a tire opposite to its proper direction of rotation,
you must drive more carefully, since the tire is no longer being used
as designed. This is particularly important on wet roads. You must

replace or remount the tire as soon as possible in order to restore the
correct direction of rotation.
Rotating tires
To help ensure even wear on all tires, regular tire rotation according
to the diagram ⇒ fig. 110 is recommended. In this way all tires can
have about the same service life.
Volkswagen recommends that you have your tires rotated by an au-
thorized Volkswagen dealer or authorized Volkswagen Service Facili-
ty.
Tires more than 6 years old
Tires age even if they are not being used. Physical and chemical pro-
cesses reduce tire strength and performance and cause them to
harden and become brittle. Old tires can fail suddenly and without
warning.
Volkswagen recommends replacing tires that are 6 years and older.
This also applies to tires that look new (an unused spare and the tire
on the compact spare wheel) or that seem to still be usable with tread
depth that has not yet reached the legal minimum depth ⇒ .
The age of each tire can be determined with the manufacturing date
that is part of the U.S. DOT tire identification number (4).) ⇒ Tire label-
ing.
Tire storage
Mark tires before removing them to help make sure that the previous
location (left, right, front, rear) and rolling direction can be maintained
when remounting them. Store tires in a cool, dry and preferably dark
place. Do not store tires mounted on wheels standing up.
Tires not mounted on wheels should be covered to help protect them
from dirt and stored vertically (sitting on the tread).
WARNING
Aggressive fluids and materials can cause visible and invisible
tire damage that can cause tire blowouts.
Always keep chemicals, oils, grease, fuels, braking fluids and
other aggressive substances away from tires.

Damaged wheel rims must be replaced, and you must never take
them apart or try to repair them yourself. Have an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility re-
pair them for you ⇒ .
Wheel rims with bolted decorative covers
Light-alloy wheels may have interchangeable decorative covers at-
tached to the rim with self-locking screws. If you want to replace
damaged wheel covers, contact your authorized Volkswagen dealer
or authorized Volkswagen Service Facility.
WARNING
Using improper or damaged wheel rims can affect driving safe-
ty, cause accidents and severe personal injury.
Use only wheel rims approved for the vehicle.
Regularly check wheel rims for damage and replace them if
necessary.
WARNING
Improper loosening and tightening of the bolts on wheel rims
with bolted rim rings can cause accidents and severe personal
injury.
Never loosen bolted connections on wheel rims with bolted
rim rings.
Have all work on wheel rims with bolted rim rings performed
by an authorized Volkswagen dealer or authorized Volkswagen
Service Facility.
New and replacement tires

Install only radial tires only of the same make, the same dimen-
sions (tread circumference), and similar tread profile on all 4 wheels.
The tread depth of new tires can differ between tire models and
manufacturers because of different design features and tread design.
Replacing tires
Tires should be replaced in pairs and not individually (both front
tires or both rear tires at the same time) ⇒ .
Replace tires only with tires that have the same specifications, in-
cluding width and diameter, load and top speed rating as the tires
approved by Volkswagen for your vehicle and model.
Never use tires that are larger or wider than the dimensions of the
tires approved by Volkswagen for your vehicle and model. Larger
tires could scrape and rub on the vehicle body or other parts of the
vehicle.
Tire Pressure Monitoring System (TPMS) considerations
Factory-installed wheels are equipped with a sensor that constantly
monitors tire pressure, then transmits this information to the TPMS ⇒ 
Tire Pressure Monitoring System (TPMS). If you are going to replace
the wheels, make sure that the new wheels also have sensors that
are compatible with the TPMS on your vehicle. New wheels with sen-
sors have to be recognized and integrated into the system. The new
wheels and sensors are recognized and integrated when driving off
the first time.
If you install wheels that do not have sensors, or have sensors that
are not compatible, the TPMS will not work properly. In this case, the
TPMS will not be able to monitor tire pressure or warn you if pressure
is low. An error message may appear in the instrument cluster display
or the TPMS will switch itself off.
Whenever you change sensors, you have to install new valves and
seals. Please see an authorized Volkswagen dealer of an authorized
Volkswagen Service Facility.
Always drive with the valve caps securely installed. We recom-
mend using factory-supplied valve caps. Ask an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility to
replace lost caps.
If you install new tires that differ the original Volkswagen specifica-
tions, for your vehicle and model, the benchmark tire inflation pres-

sure values stored in your vehicle's TPMS may have to be adjusted
(reprogrammed). This requires professional assistance. For more
information, contact your authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
Installing replacement tires with steel cord body plies in the tire side-
wall may cause malfunction of the TPMS, and is not recommended
(cord material information in molded on the tire sidewall).
Always check the TPMS indicator light after replacing one or more
tires on your vehicle. If the indicator light is on, the TPMS is not work-
ing properly. Your replacement tire might be incompatible with the
system, or some component of the TPMS may be damaged.
For detailed information about TPMS, how it works and what you
need to know ⇒ Tire Pressure Monitoring System (TPMS).
WARNING
New tires tend to be slippery and must be broken in.
Always drive with special care for the first 350 miles (560 km)
to help reduce the risk of losing control, a collision, and serious
personal injuries.
WARNING
Tires must have the required clearance. Tires that do not have
enough clearance can rub against parts of the vehicle body,
suspension, and brake system, causing brake system failure,
tread delamination, and sudden blowouts.
Always make sure that new tires are not larger than the tires
approved for your vehicle and that the new tires do not rub
against parts of the vehicle.
NOTICE
When switching to different tires, make certain the valves and
sensors are not damaged.
Never drive without valve stem caps. The valves and sensors
could be damaged.

If a sensor for the Tire Pressure Monitoring System must be
replaced, the corresponding valve must be replaced at the same
time.
Always dispose of old tires in accordance with legal require-
ments.
TPMS wheel sensors are classified as Perchlorate Material –
special handling may apply. Obey all legal requirements regarding
handling and disposal of these components – 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.
If the replacement wheel is different from the tires that you have
mounted on your vehicle — for example, winter tires, wider, low-
profile tires or a compact spare — only use the replacement wheel for
a short time and drive cautiously.
Replace it with a tire matching the others on your vehicle as soon
as possible.
Although tire size specifications can be the same, the actual di-
mensions may differ from those nominal values for different tire
makes, or the tire contours may be significantly different.

The Tire Pressure Monitoring System is configured at the factory
with the correct tire inflation pressure applicable for the vehicle
model, engine and factory-installed tires. The tire inflation pressure
is listed on the tire inflation pressure label on the driver door jamb⇒ ,
Tire inflation pressure. The tire inflation pressures for the road tires
are listed on this label. The inflation pressure for the compact spare
is as specified on the tire pressure label or on a separate label for
the compact spare, if there is one. In the event of a discrepancy be-
tween the above figures and the tire pressures listed on the tire infla-
tion pressure label, the pressures listed on the label are the ones
you should use. The listed pressure applies to all road tires. If differ-
ent tires are installed that do not have the same cold tire inflation
pressure as the tires originally installed on your vehicle, the Tire
Pressure Monitoring System cannot properly monitor tire inflation
pressures unless the TPMS is reset to the new tire pressures
⇒ page 295. Authorized Volkswagen dealers and authorized
Volkswagen Service Facilities have the necessary special tools and
can reset the TPMS for the new tires on your vehicle.

Driving style.
Unbalanced wheels.
Wheel alignment.
Driving style – Fast cornering, hard acceleration and braking increase
tire wear. If you experience increased tire wear under normal driving
conditions, have the vehicle suspension checked by an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility.
Unbalanced wheels – The wheels on a new vehicle are balanced.
When driving, however, various conditions can cause a wheel to be-
come unbalanced. Unbalanced wheels can cause wear to the steer-
ing and suspension systems. Have all wheels rebalanced. A wheel
must always be rebalanced if a new tire has been mounted.
Wheel alignment – Incorrect wheel alignment causes excessive and
uneven tire wear, impairing vehicle safety. If you notice excessive or
uneven tire wear, have the wheel alignment checked by an author-
ized Volkswagen dealer or an authorized Volkswagen Service Facili-
ty.
WARNING
Unusual vibrations or pulling to one side can indicate tire dam-
age.
Reduce speed immediately and stop when it is safe to do so.
Check tires and wheel rims for damage.
Never drive with a damaged tire or rim. Get expert assistance
instead.
If no external damage is visible, slowly and carefully drive to
the nearest authorized Volkswagen dealer, authorized
Volkswagen Service Facility, or other qualified workshop and
have the vehicle checked.
