Changing a tire VOLKSWAGEN CC 2013 Owners Manual

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.

Do not use “comfort valve caps”, as these do not seal proper-
ly and could therefore cause damage to the sensors.
When changing or rotating the tires, be careful not to damage
the valves or sensors.
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.

WARNING
The effectiveness of ESC can be significantly reduced if other
components and systems that affect vehicle dynamics, includ-
ing but not limited to brakes, tires, and other systems men-
tioned above, are not properly maintained or functioning.
Always remember that vehicle alterations or modifications
can affect the functioning of the ABS, BAS, ASR, EDL, and ESC
systems.
Changing the vehicle suspension or using an unapproved
tire/wheel combination can change the way the ABS, BAS, ASR,
EDL, and ESC systems work and reduce their effectiveness.
The effectiveness of ESC is also determined by the tires fitted
⇒  Tires and wheels.
All 4 wheels must be equipped with identical tires in order for
ESC and ASR to work properly. Differences in the tread circumfer-
ence of the tires can cause the system to reduce the engine power
when it is not expected.
If ABS is not working, ESC, ASR, and EDL will also not work.
You may hear noises when these systems are active.

manually.

WARNING
Changing the vehicle's suspension including use of unap-
proved tire-rim combinations can change airbag performance
and increase the risk of serious personal injury in a crash.
Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
Never use tire-rim combinations that have not been approved
by Volkswagen.
WARNING
Leaving the optional safety belt extender attached to the safety
belt buckle on the front passenger seat when the safety belt is
not being used will prevent the Advanced Airbag System from
working properly and can increase the risk of serious personal
injury in a collision.
Leaving the extender attached to the safety belt buckle when
the front seat is occupied and the safety belt is not being used
will signal to the airbag control unit that the front passenger
seat is occupied and that the safety belt is being used. The
electronic control unit for the airbag system will then receive
incorrect information that will
– cause the safety belt pretensioner to deploy unnecessarily
in collisions and
– cause the front passenger airbag to deploy later in colli-
sions in which the front airbag would otherwise be triggered
earlier to help protect an unrestrained front seat passenger.
Always remove the safety belt extender when it is not needed
and stow it safely.
Never use the safety belt extender to secure a child restraint.

After changing a wheel, have the wheel bolt tightening torque
checked with an accurate torque wrench.
After changing a wheel or tire, reset the Tire Pressure Moni-
toring System ⇒  Tire Pressure Monitoring System (TPMS).
