miles (kilometers) at low speeds in the 3 hour period before the tire
pressure is measured or adjusted.
Curb weight
The weight of a motor vehicle with standard equipment including the
maximum capacity of fuel, oil, and coolant, air conditioner, and addi-
tional weight of optional equipment.
Extra load tire
A tire designed to operate at higher loads and at higher inflation pres-
sures than the corresponding standard tire.
Gross Axle Weight Rating (GAWR)
The load-carrying capacity of a single axle system, measured where
the tire contacts the ground.
Gross Vehicle Weight Rating (GVWR)
The maximum loaded weight of the vehicle.
Groove
The space between 2 adjacent tread ribs.
Load rating (code)
The maximum load that a tire is rated to carry for a given inflation
pressure. You may not find this information on all tires because it is
not required by law.
Maximum load rating
The load rating for a tire at the maximum permissible inflation pres-
sure for that tire.
Maximum loaded vehicle weight
The total of:
Curb weight.
Accessory weight.
Vehicle capacity weight.
Production options weight.
Maximum (permissible) inflation pressure
The maximum cold inflation pressure to which a tire may be inflated.
Also called “maximum inflation pressure.”

Recommended inflation pressure
The tire pressure recommended by the vehicle manufacturer for a tire
of a specified size that has not been driven for more than a couple of
miles (kilometers) at low speeds in the 3 hour period before the tire
pressure is measured or adjusted.
Reinforced tire
A tire designed to operate at higher loads and at higher inflation pres-
sures than the corresponding standard tire.
Rim
The outer edge of a wheel upon which the tire beads are seated.
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 inflat-
ed 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. 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

There are limits to the load any vehicle or any tire can carry. A vehicle
that is overloaded will not handle well and is more difficult to stop.
Overloading can damage important parts of the vehicle. Overloading
can also lead to blowout, sudden loss of pressure or other tire failure
that can cause loss of control.
Your safety and the safety of your passengers depends on making
sure that load limits are not exceeded. Vehicle load includes every-
body and everything in and on the vehicle. These load limits are
technically referred to as the vehicle's Gross Vehicle Weight Rating
(GVWR).
The GVWR includes the weight of the basic vehicle, all factory-
installed and other accessories, a full tank of fuel, oil, coolant and
other fluids plus maximum load. The maximum load includes the
number of passengers that the vehicle is intended to carry (seating
capacity) with an assumed weight of 150 lbs (68 kg) for each passen-
ger at a designated seating position and the total weight of any lug-
gage in the vehicle. If you tow a trailer, the weight of the trailer hitch
and the tongue weight of the loaded trailer must be included as part
of the vehicle weight. At altitudes above 3000 ft (1000 m), combined
towing weight (vehicle plus trailer) must be reduced by 10% for every
3000 ft (1000 m).
The Gross Axle Weight Rating (GAWR) is the maximum load that
can be carried at each of the vehicle's 2 axles (by the front or rear
tires). GVWR and GAWR are listed on the safety compliance label on
the driver door jamb. Because there is an upper limit to your vehicle's
total weight (GVWR), the weight of whatever is being carried (includ-
ing the weight of a trailer hitch and the tongue weight of the loaded
trailer) is also limited. More passengers, or passengers who are heav-
ier 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 oc-
cupants and luggage or other cargo that the vehicle can carry.

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.
