2014 VOLKSWAGEN PASSAT CC warning

Rim diameter
The nominal diameter of the wheel's tire bead seating surface. If you change your wheel size, to wheels of a different diameter, you will have to purchase new tires to match the new wheels.
Rim size
Designation means rim diameter and width.
Rim type designation
The industry or manufacturer's designation for a rim by style or code.
Rim width
The nominal distance between wheel rim flanges.
Section width
The linear distance between the exteriors of the sidewalls of an inflated tire, excluding elevations due to labeling decoration, or protective bands.
Sidewall
The portion of a tire between the bead and the tread.
Sidewall separation
The parting of the rubber compound from the cord material in the sidewall.
Speed rating (letter code)
A standardized letter code indicating the maximum speed at which a tire is designed to be driven for extended periods of time. The ratings range from 93 mph or 150 km/h (“P”) to 186 mph or (300 km/h) “Y”.
The speed rating letter code, where applicable, is molded on the tire sidewall, Tire labeling. You may not find this information on all tires because it is not required by law.
Tire Pressure Monitoring System
A system that detects when at least one of a vehicle's tires is underinflated and illuminates a low tire-pressure warning light.
Tread
The portion of a tire that normally touches the road.
Tread rib
A tread section running circumferentially around a tire.
Tread separation
Tire failure caused by the tread pulling away from the tire carcass.
Tread wear indicators (TWI)
Raised areas within the main tread grooves that show, visually, when tires are worn and near the end of their useful life, Tread depth and tread wear indicators.
Uniform Tire Quality Grading (UTQG)
A tire information system developed by the U.S. National Highway Traffic Safety Administration (NHTSA) that is designed to help buyers compare tires. UTQG is not a safety rating, nor is it a guarantee that a tire will last for a certain number of miles or perform a certain way. It gives tire buyers more information to compare with factors such as price, brand loyalty and dealer recommendations. Under UTQG, tires are graded by the tire manufacturers in 3 areas: tread wear, traction and temperature resistance. UTQG information is molded into the tire sidewalls.

label on the driver door jamb. Your vehicle has 5 total seating positions: 2 in the front and 3 in back. Each seating position has a safety belt. Because there is an upper limit to your vehicle's total weight (GVWR), the weight of whatever is being carried (including the weight of a trailer hitch and the tongue weight of the loaded trailer) is also limited. More passengers, or passengers who are heavier than the assumed 150 lbs (68 kg), mean that less weight can be carried as luggage or other cargo. The tire pressure label on your Volkswagen also lists the maximum combined weight of all of the occupants and luggage or other cargo that the vehicle can carry.
WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or other accident, serious personal injury, and even death.
x Carrying more weight than your vehicle was designed to carry will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
x The brakes on a vehicle that has been overloaded may not be able to stop the vehicle in a safe distance.
x Tires on a vehicle that has been overloaded can fail suddenly, including a blowout and sudden deflation, causing loss of control and a crash.
x Always make sure that the total load being transported – including the weight of a trailer hitch and the tongue weight of a loaded trailer – does not make the vehicle heavier than the vehicle's Gross Vehicle Weight Rating.
Determining the correct load limit

WARNING
Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control, collision, serious personal injury or even death.
x When the warning symbol appears in the instrument cluster, stop and inspect the tires.
x Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect the handling of the vehicle and stopping ability.
x Incorrect tire pressures and/or underinflation can also lead to sudden tire failure, including a blowout and sudden deflation, causing loss of vehicle control.
x 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 pressure.
x The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure specified for the tires installed on the vehicle.
x 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.
x Always maintain correct cold tire inflation pressure so that TPMS can do its job.
x Always inflate tires to the recommended and correct tire pressure before driving off.
x 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.
x Excessive speed and/overloading can cause heat build-up, sudden tire failure, and loss of control.
x If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well.
x If the tire is not “flat” and you do not have to change a wheel immediately, drive carefully and at reduced speed to the nearest service station to check the tire pressure and add air as required.
x 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
x 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.
x 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.
x Do not use “comfort valve caps.” They do not seal properly and can damage the sensors.
x When replacing or rotating tires, make certain the valves and sensors are not damaged.
x 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.
x When replacing the valve cores, use only nickel-plated replacement cores.
x 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.

Tire Pressure Monitoring System (TPMS) 
Your vehicle's Tire Pressure Monitoring System (TPMS) uses the Anti-lock Brake System (ABS) sensors to indirectly check the tire pressure of all 4 tires while you are driving. The sensors monitor the tread circumference (rolling circumference) and vibration characteristics of the individual tires. TPMS warns if there is a significant loss of pressure in one or more tires while the vehicle is moving. Pressure loss is signaled by the indicator light Ç (described below) as well as by text warnings in the instrument cluster display if your vehicle has this display (Multi-Function Indicator- MFI).
The original benchmark pressure is the recommended maximum load cold tire inflation pressure for the tires that come with your vehicle. This pressure is listed on the tire pressure label on the driver door jamb, Tires and wheels. After adjusting the tire pressures in all 4 tires, you must confirm and store the new cold inflation pressures using the Settings menu in the instrument cluster, Settings menu, which changes the benchmark pressure to match the current pressure of the tires on your vehicle.
Recalibrating the TPMS to reset the benchmark cold tire inflation pressure is explained below, Tire Pressure Monitoring System (TPMS).

x The Tire Pressure Monitoring System must be recalibrated whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change, Tire Pressure Monitoring System (TPMS).
WARNING
Improper recalibration can cause the TPMS to give false warnings or to give no warning despite dangerously low tire pressure, Tire Pressure Monitoring System (TPMS).
Underinflation increases fuel consumption and tire wear.
Do not rely solely 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.
When you take delivery of the vehicle, the Tire Pressure Monitoring System is calibrated for the factory-recommended cold tire inflation pressure for the tires on your vehicle, as shown on the label inside the driver door, Tire inflation pressure.

x The system must be recalibrated whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change, Tire Pressure Monitoring System (TPMS).
x 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 inside the driver door ⇒ page 184, Tire inflation pressure.
x If 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 accurate tire pressure gauge. Low tire pressure usually cannot be determined by looking at the tire. This is especially true of low-profile tires.
If you have work done on your wheels or tires, inform the workshop that the vehicle is equipped with a Tire Pressure Monitoring System (TPMS).
New tires may expand slightly the first time they are driven at high speeds, which can trigger a tire pressure warning. Remember that tire pressure can only be properly measured when the tire is “cold”, Tires and wheels.
Only replace old tires with tires that have been approved by Volkswagen for your vehicle type.
