2010 VOLKSWAGEN CC Owners Manual

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.

WARNING
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.

Tire Pressure Monitoring System (TPMS)

WARNING
Incorrect tire pressures and/or underinflation can cause sudden
tire failure, loss of control, collision, serious personal injury or
even death.
When the warning symbol appears in the instrument cluster,
stop and inspect the tires.
Incorrect tire pressure and/or underinflation can cause in-
creased tire wear and can affect the handling of the vehicle and
stopping ability.
Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
The driver is responsible for the correct tire pressures for all
tires on the vehicle. The recommended tire pressure values are
listed on a sticker inside the driver door ⇒  Tire inflation pres-
sure.
The TPMS can only work correctly when all tires on the vehi-
cle are filled to the correct cold tire inflation pressure specified
for the tires installed on the vehicle.
Using incorrect tire pressure values can cause accidents or
other damage. Always inflate the tires to the correct specified
cold tire pressure values for the tires installed on the vehicle.
Always maintain correct cold tire inflation pressure so that
TPMS can do its job.
Always inflate tires to the recommended and correct tire
pressure before driving off.
Driving with underinflated tires causes them to flex (bend)
more, letting them get too hot, resulting in tread separation,
sudden tire failure, and loss of control.
Excessive speed and/overloading can cause heat build-up,
sudden tire failure, and loss of control.
If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
If the tire is not “flat” and you do not have to change a wheel
immediately, drive carefully and at reduced speed to the near-
est service station to check the tire pressure and add air as re-
quired.

When replacing tires or wheel rims on vehicles equipped with
TPMS always read and heed the information and all WARNINGS
regarding tires and wheels ⇒  Tires and wheels.
NOTICE
The wheel electronics are attached to special aluminum valves
on the wheels. These valves are screwed on rigidly. Never bend
the valves “into position” when checking and adjusting tire
pressure.
Missing valve stem caps can cause damage to the valves as
well as to the TPMS sensors. To help prevent damage, always
use valve stem caps like those originally installed at the factory.
The caps must be screwed on tightly. Do not use metal valve
stem caps.
Do not use “comfort valve caps.” They do not seal properly
and can damage the sensors.
When replacing or rotating tires, make certain the valves and
sensors are not damaged.
The aluminum valves that are installed should be replaced
after about 6 years of use because of aging in the rubber seals.
The valves can be replaced when a tire is changed. Do not reuse
aluminum valves after they are removed. They must be replaced.
The tire pressure sensor can be reused.
When replacing the valve cores, use only nickel-plated re-
placement cores.
The batteries in the wheel electronics last up to 10 years. It is
not possible to replace the batteries. The entire device must be
replaced.
Underinflation increases fuel consumption and tire wear.
Dispose of the wheel electronics and the old batteries in an envi-
ronmentally responsible manner. Batteries of the type used in the
wheel electronics may contain Perchlorate Material. Special handling
may apply. See www.dtsc.ca.gov/hadardouswaste/perchlorate. Obey
all applicable legal requirements regarding proper disposal.

Do not rely only on the Tire Pressure Monitoring System. Check
your tires regularly to make sure they are properly inflated and have
no signs of damage, such as punctures, cuts, cracks, and blisters.
Remove any objects that become embedded in the tire tread but have
not penetrated into the body of tire itself.
The Tire Pressure Monitoring System checks for the factory-
recommended inflation pressure, as shown on the label inside the
driver door ⇒  Tire inflation pressure.
For replacement tires that require a different inflation pressure, the
TPMS must be adjusted to the new pressure specification by an au-
thorized Volkswagen dealer or an authorized Volkswagen Service
Facility. Only one value can be entered for each tire; see the tire infla-
tion pressure label on the driver door pillar ⇒  Tire inflation pressure.
To help prevent damage to the sensor and valve, do not put exces-
sive force on the valve when checking the tire pressure. Do not try to
bend the valve.
If sensors have to be replaced, have the valves changed at the
same time.
The tire valve gaskets must be replaced whenever a tire is mount-
ed on the rim. Your authorized Volkswagen dealer or authorized
Volkswagen Service Facility has a valve seal and gasket kit for this
purpose. Always make sure that a valve seal and gasket kit is also
used whenever a sensor is replaced.
If you have to adjust the tire pressure on a “warm” tire, fill the tire
with 2.0 - 4.35 psi (20 - 30 kPa) more than the pressure specified on
the tire pressure label.
When the TPMS determines that the air pressure in at least one
tire is too low, carefully check the pressure in all 4 tires with an accu-
rate tire pressure gauge. Low tire pressure usually cannot be deter-
mined by looking at the tire. This is especially true of low-profile tires.
A Declaration of Compliance with the United States FCC and
Industry Canada regulations is found in the Consumer Information
section of this Manual ⇒  Declaration of Compliance, Telecommunica-
tions and Electronic Systems.

There may be differences between the pressure readings from a
tire pressure gauge and the pressures registered by the Tire Pressure
Monitoring System. The electronic TPMS is more accurate.
If you have work done on your wheels or tires, inform the work-
shop that the vehicle is equipped with a Tire Pressure Monitoring
System that has sensors in the wheels.
