2018 VOLKSWAGEN CC warning

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.

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.

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

If the tire is not “flat” and you do not have to change the tire
or wheel immediately, drive at reduced speed to the nearest
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 WARN-
INGS in the section ⇒  Tires and wheels.
WARNING
Failure to heed warning lights and instrument cluster text mes-
sages can cause the vehicle to break down in traffic and result
in a collision and serious personal injury.
Never ignore warning lights or text WARNINGS.
Always stop the vehicle as soon as it is safe to do so.
NOTICE
Failure to heed warning lights or text WARNINGS can result in
vehicle damage.
Tire Pressure Monitoring System (TPMS)

Fig. 117 Display screen in the instrument cluster: Current tire pres-
sures in psi.

The Tire Pressure Monitoring System uses a pressure sensor in each
wheel. Signals from the sensors are transmitted to the TPMS.
The TPMS checks the tire pressure of all 4 tires while you are driving
and warns if there is a loss of pressure while the vehicle is moving.
Pressure loss that is 25% or more of the benchmark value pro-
grammed into the system is signaled by the indicator light (telltale)
described above, by acoustic warnings, and by text messages in the
instrument cluster display.
If you mount tires of a different size than the factory installed tires, an
authorized Volkswagen dealer or an authorized Volkswagen Service
Facility can adjust the benchmark TPMS tire pressure to match the
new tires. Without this adjustment, TPMS may not work correctly or at
all.
The tire pressure recommended for the tires originally installed on the
vehicle is on a sticker on the driver door jamb ⇒  Tire inflation pres-
sure.
Display in the instrument cluster
The display in the instrument cluster shows the vehicle with the actual
and benchmark tire pressures of all 4 road wheels ⇒ fig. 117

Spare wheel or compact spare wheel
The spare wheel or compact spare wheel has no tire pressure sen-
sor. When the spare or compact spare wheel is mounted on the vehi-
cle, the Tire Pressure Monitoring System (TPMS) indicator light will
flash in the instrument cluster display. The TPMS continues to moni-
tor the other 3 wheels.
Tire storage
If the tires do not move for an extended period of time, the sensors
will not transmit tire pressures to the system. This saves sensor bat-
tery life. When the ignition is switched on, the sensors transmit sig-
nals to the Tire Pressure Monitoring System.
WARNING
Incorrect tire pressure can cause sudden tire failure, loss of
vehicle control and serious personal injury.
Always check and correct air pressure in all 4 tires, particu-
larly after changing, exchanging, or repairing tires.
After that, always make sure that all 4 tires are inflated to the
correct tire pressure for the tires installed on the vehicle.
See the tire pressure label ⇒  Tire inflation pressure and the
Owner's Literature for recommended cold tire inflation pressure
and other important information.
When replacing tires or wheel rims on vehicles equipped with
TPMS, always read and heed all of the information and WARN-
INGS ⇒  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 tire air valve caps could result in damage to the
valves, as well as to the sensors on the Tire Pressure Monitoring
System. Therefore, make sure your valve caps conform to the
specifications of those originally installed on the vehicle and
that they are always tightly and properly screwed on to the
valves. Do not use metallic valve caps.
