DOT 4 VOLKSWAGEN CC 2010 Owners Manual

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.

WARNING
Improper use of a spare wheel or a compact spare wheel can
cause loss of vehicle control, a crash or other accident, and se-
rious personal injury.
Never use a spare wheel or compact spare wheel if it is dam-
aged or worn down to the wear indicators.
In some vehicles, the spare wheel or compact spare wheel is
smaller than the original tire. A smaller compact spare wheel is
identified with a sticker and the words “50 mph” or “80 km/h”.
This is the maximum permissible speed when driving with this
tire.
Never drive faster than 50 mph (80 km/h) with a compact
spare wheel. Avoid full-throttle acceleration, heavy braking, and
fast cornering!
Never drive more than 125 miles (200 km) if a compact spare
wheel is installed on the front axle (drive axle).
Replace the compact spare with a normal wheel and tire as
soon as possible. Compact spare tires are designed for brief
use only.
Regularly check the U.S. DOT Tire Identification Number (TIN)
to determine the age of the compact spare wheel ⇒  Tire label-
ing. Tires age even if they are not being used and can fail sud-
denly, especially at higher speeds.
Tires that are more than 6 years old can only be used in an
emergency and then with special care and at lower speeds.
The compact spare wheel must always be secured with the
wheel bolts provided by the factory.
Never drive using more than one compact spare wheel.
After installing the compact spare wheel, the tire pressure
must be checked as soon as possible ⇒  Tire inflation pressure.
Snow chains cannot be used on the compact spare wheel. If
you must use snow chains and have a compact spare wheel
mounted, move the compact spare wheel to the rear axle if a
front tire has to be replaced. The tire taken off the rear axle can
then be used to replace the flat front tire. Be sure you do not
change the tire's direction of rotation. Install the snow chains
on the full-sized road tire.

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. 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 underin-
flated 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 ⇒ page 261.
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.
U.S. DOT Tire Identification Number (TIN)
A tire's serial number. It begins with the letters “DOT” (“Department of
Transportation”) and indicates that the tire meets all federal stand-
ards. The next 2 numbers or letters indicate the plant where the tire

Check the information on the container for the brake fluid you want to
use to make sure it meets the requirements for your vehicle.
Brake fluid that complies with VW Standard 501 14 can be pur-
chased from your authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
If this special brake fluid is not available you may – under these cir-
cumstances – use another high quality brake fluid that complies with
U.S. Federal Motor Vehicle Safety Standard (FMVSS) 116 DOT 4 ⇒ 
.
Please note, however, that not all brake fluids that comply with U.S.
Federal Motor Vehicle Safety Standard FMVSS 116 DOT 4 have the
same chemical composition. Some of these brake fluids can contain
chemicals that could, over time, degrade or damage internal parts of
the vehicle’s brake system.
Volkswagen therefore recommends that you use brake fluid that ex-
pressly complies with VW Standard 501 14 for optimum brake sys-
tem performance over the long term.
Brake fluid level
The fluid level in the transparent brake fluid reservoir must always be
between the MIN and MAX marking ⇒ .
On some vehicles, engine components block the view of the brake
fluid reservoir and make it impossible to see the brake fluid level. If
you cannot clearly see the brake fluid level in the brake fluid reservoir,
please see an authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
The brake fluid level drops slightly when the vehicle is being used as
the brake pads wear and the brakes are automatically adjusted.
Changing brake fluid
Brake fluid must be changed according to the service schedule in
your ⇒ Booklet Warranty and Maintenance. Have the brake fluid
checked by an authorized Volkswagen dealer or an authorized
Volkswagen Service Facility. Refill only with new brake fluid that
meets the standards listed above.

WARNING
Brake failure and reduced brake performance can be caused by
not having enough brake fluid in the reservoir or by old or in-
correct brake fluid.
Check the brake system and brake fluid level regularly.
Always change the brake fluid according to the service
schedule in your ⇒ Booklet Warranty and Maintenance.
Hard braking with old brake fluid may cause vapor lock. Va-
por lock reduces braking performance, increases stopping dis-
tances and can even cause total brake failure.
Always make sure that only the correct brake fluid is used.
Only use brake fluid that expressly conforms to VW Standard
501 14 or, if it is not available, only use a high-quality brake flu-
id that conforms to U.S. Standard FMVSS 116 DOT 4 require-
ments.
Using another brake fluid, or one that is not of high quality,
can impair the function of the brake system and reduce its ef-
fectiveness. If the container does not say that the brake fluid
complies with VW Standard 501 14, or U.S. Standard
FMVSS 116 DOT 4, do not use it.
The brake fluid must be new.
WARNING
Brake fluid is poisonous.
To reduce the risk of poisoning, never use food, beverage or
other non-original containers to store brake fluid. Someone
might be misled by the original label on the container, or by the
shape of the container, and drink the brake fluid. This could oc-
cur even if you relabel the container as “brake fluid.”
Only store brake fluid in the closed, original container and
keep it out of the reach of children.
NOTICE
Brake fluid will damage vehicle paint, plastic parts, and tires.
Wipe any brake fluid off vehicle paint and other vehicle parts
immediately.
