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.
Indicator light (telltale)

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

Tire pressure display screen
⇒ fig. 117 Meaning
(1) Tire pressure warning, left rear
tire.
(2) Current tire pressure, front left
tire.
(3) Benchmark pressure, front tires
(4) Current tire pressure, front right
tire.
(5) No data received, right rear tire.
(6) Benchmark pressure, rear tires

If the tire pressure is too low, the relevant tires and the respective
readings are highlighted in yellow.
Each tire, including the spare (if provided), should be checked month-
ly when cold and inflated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard or tire inflation pres-
sure label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a
Tire Pressure Monitoring System (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly underinflated
tire causes the tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life, and may affect
the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indi-
cator to indicate when the system is not operating properly. The
TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continuously illuminat-
ed. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always check the TPMS mal-
function telltale after replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.

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.

Heat buildup in the passenger and luggage compartment of a
parked vehicle can result in temperatures in the vehicle that are
much higher than the outside temperatures, particularly in
summer. Temperatures can quickly reach levels that can cause
unconsciousness and death, particularly to small children.
NOTICE
Always be careful when you park in areas with parking barri-
ers or high curbs. These vary in height and could damage your
bumper and related parts if the front of your vehicle hits a barrier
or curb that is too high while you are getting into or out of a
parking spot. To help prevent damage, stop before the tires of
your vehicle touch a parking barrier or curb.
Always be careful when you enter a driveway or drive up or
down steep ramps or over curbs or other obstacles. Parts of the
vehicle close to the ground may be damaged (such as bumper
covers, spoilers, and parts of the engine, suspension, and ex-
haust systems).
