Volkswagen Golf SportWagen (2015 year). Instruction - part 13

WARNING

Incorrect tire pressure can cause a sudden tire failure or blowout, loss of control, collision,
serious personal injury, and even death.

Always inflate tires to the recommended and correct cold tire pressure before driving off.
Low tire pressure can cause tires to get too hot, resulting in tread separation, sudden loss

of pressure, and blowouts. Tires with excessively low pressure flex (bend) more, which can
cause the tire to overheat and fail suddenly without warning.

Excessive speed and/or overloading can cause heat buildup, sudden tire failure including

a blowout and sudden deflation 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.

Regularly check tire inflation pressure, at least once a month, and also especially before a

long trip.

Check the pressure in all 4 tires when the tires are still cold. Never reduce air pressure in

warm tires to match cold tire inflation pressure.

NOTICE

Make sure not to jam the tire pressure gauge into the valve stem. Otherwise you can dam-

age the tire valves.

Driving without valve caps, with the wrong valve caps, or with valve caps that are not

properly screwed on can damage the tire valves. 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 caps or “comfort” valve stem caps.

Underinflation increases fuel consumption.

When the TPMS warns that the pressure in at least one tire is too low, check the tire pressure in

all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be spotted by looking

at the tire. This is especially true for low-profile tires. When checking the tire pressures, refer to

⇒ Tire

Pressure Monitoring System (TPMS).

The Tire Pressure Monitoring System is configured at the factory with the
correct tire inflation pressure applicable for the vehicle model, engine and
factory-installed tires. The tire inflation pressure is listed on the tire infla-

tion pressure label on the driver door jamb

⇒

fig. 106

. The tire inflation

pressures for the road tires are listed on this label. The inflation pressure
for the compact spare is as specified on the tire pressure label or on a
separate label for the compact spare, if there is one. In the event of a dis-
crepancy between the above figures and the tire pressures listed on the
tire inflation pressure label, the pressures listed on the label are the ones
you should use. The listed pressure applies to all road tires. The Tire
Pressure Monitoring System must be recalibrated whenever you change
or adjust the cold tire inflation pressures or remove and remount or
change any wheel or tire on the vehicle, even if the reinstalled or replace-
ment wheels and tires are identical to those that were removed and even if
the tire pressure does not change

Tread depth and tread wear indicators

Fig. 107 Tread pattern: Wear indicator.

Please first read and note the introductory information and heed the WARNINGS

Tread depth

Most driving situations require as much tread depth as possible and similar tread depth for the tires on
the front and rear wheels. This is especially true when driving in winter weather, at low temperatures

and under wet conditions

⇒ .

In most countries the legally permissible minimum tread depth is 1/16 in. (1.6 mm), as measured in
tread grooves next to the wear indicators. Please be sure to obey country-specific legal requirements.

Winter tires are no longer suitable for winter operation once the tread pattern is worn down to a depth
of 3/16 in. (4.8 mm).

The tread depth of new tires can differ between tire models and manufacturers because of the differ-
ent design features and tread patterns.

Tread wear indicator (TWI) in the tire

The 1/16 in. (1.6 mm) high wear indicators are molded into the bottom of the tread grooves of the

original tires running across the treads

⇒

fig. 107

. Several wear indicators are evenly spaced around

the tire. Markings on the sides of the tires (for example “TWI” or symbols) show the position of the
wear indicators.

Wear indicators show when the tires are worn down. The tires must be replaced no later than when
the tread pattern is worn down to the wear indicators.

WARNING

Worn tires are dangerous and can cause loss of vehicle control including serious personal
injuries.

Never drive a vehicle when the tread on any tire is worn down to the wear indicators, re-

place them sooner.

Worn tires do not grip the road properly, especially on wet roads, increasing your risk of

“hydroplaning” and loss of control.

Worn tires reduce the ability of your vehicle to handle well in normal and difficult driving

situations and increase braking distances and the risk of skidding.

Tire wear and damage

Please first read and note the introductory information and heed the WARNINGS

Wheel rim and tire damage is often difficult to see. Unusual vibrations or pulling to one-side can be

an indication of tire damage

⇒ .

  If you suspect tire damage, immediately reduce speed!
  Check tires and wheel rims for damage.
  If a tire is damaged, do not drive any farther. Get expert assistance.
  If no external damage is visible, slowly and carefully drive to the nearest authorized Volkswagen

dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the vehicle
checked.

Objects embedded in the tire

If embedded objects have penetrated to the inside of the tire, do not remove them! If objects are

stuck in the tread grooves of the tire, they can be removed.

If necessary, change the damaged wheel

⇒ Changing a wheel. If necessary, get professional

assistance to change the wheel.

Check tire pressure and adjust if necessary.

Tire wear

Tire wear depends on several factors, including:

  Driving style.
  Unbalanced wheels.
  Wheel alignment.

Driving style – Fast cornering, hard acceleration and braking increase tire wear. If you experience
increased tire wear under normal driving conditions, have the vehicle suspension checked by an
authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

Unbalanced wheels – The wheels on a new vehicle are balanced. When driving, however, various
conditions can cause a wheel to become unbalanced. Unbalanced wheels can cause wear to the
steering and suspension systems. Have all wheels rebalanced. A wheel must always be rebalanced if
a new tire has been mounted.

Wheel alignment – Incorrect wheel alignment causes excessive and uneven tire wear, impairing
vehicle safety. If you notice excessive or uneven tire wear, have the wheel alignment checked by an
authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

WARNING

Unusual vibrations or pulling to one side can indicate tire damage.

  Reduce speed immediately and stop when it is safe to do so.
  Check tires and wheel rims for damage.
  Never drive with a damaged tire or rim. Get expert assistance instead.
  If no external damage is visible, slowly and carefully drive to the nearest authorized

Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and
have the vehicle checked.

  Lower the variable luggage compartment floor.
  Close the rear hatch.

If the replaced wheel does not fit in the spare wheel well, stow it securely in the luggage compartment
on top of the floor covering.

If the spare wheel is different from the road wheels

If the spare is different from the road wheels, a compact spare wheel, for example, or if the road
wheels are winter tires, the spare wheel must be used only in the event of a flat tire, only for a brief

time, and only when driving with extra caution

⇒ .

Replace it with a tire matching the others on your vehicle as soon as possible.

Please heed the following:

Do not drive faster than 50 mph (80 km/h)!
Avoid full-throttle acceleration, hard braking, and fast cornering!

Do not use snow chains on the compact spare wheel

⇒ Snow chains.

After installing the spare wheel or compact spare wheel, check the tire pressure as soon as possi-

ble

⇒ Tire inflation pressure.

Check the tire inflation pressure of the spare or compact spare whenever you check the tire pressure
of the road wheels, at least once a month. Inflate a spare wheel to the cold tire pressure specified for
the vehicle's road wheels on the tire pressure label; inflate a compact spare wheel to the cold tire
pressure specified for the compact spare on the tire pressure label or on a separate label for the
compact spare, if there is one.

WARNING

Improper use of a spare wheel or a compact spare wheel can cause loss of vehicle control, a
crash or other accident, and serious personal injury.

Never use a spare wheel or compact spare wheel if it is damaged 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 labeling. Tires age even if they are not being used and can fail

suddenly, especially at higher speeds.

Tires that are more than 6 years old can only be used in an emergency and then with spe-

cial 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.

NOTICE

When the spare wheel or compact spare is being used, the TPMS indicator light can light up

after a couple of minutes

⇒ Tire Pressure Monitoring System (TPMS).

If possible, attach the spare wheel, compact spare wheel, or the wheel you took off the vehicle

securely in the luggage compartment.

Unidirectional tires

Unidirectional tires are designed to rotate only in one direction. Unidirectional tires have arrows on the
sidewalls that show the direction of rotation. Make sure you mount the tire so that it rotates in the
proper direction. The tire's performance with regard to hydroplaning, traction, noise, and wear is worse
if it is not mounted in the proper direction of rotation.

If you have to mount a tire opposite to its proper direction of rotation, you must drive more carefully,
since the tire is no longer being used as designed. This is particularly important on wet roads. You
must replace or remount the tire as soon as possible in order to restore the correct direction of rota-
tion.

Some tire manufacturers label tires with a maximum permissible road speed above 149 mph
(240 km/h) with the letter combination “ZR.”

WARNING

Using incorrect or unmatched tires and/or wheels or improper tire and wheel combinations
can lead to loss of control, collision and serious personal injury.

Always use tires, wheels and wheel bolts that meet the specifications of the original facto-

ry-installed tires or other combinations that have been specifically approved by the vehicle
manufacturer.

All 4 wheels must be fitted with radial tires of the same type, the same size (tread circum-

ference), and the same tread pattern. Driving with different tires reduces vehicle handling and
can lead to a loss of control.

Never drive faster than the maximum speed for which the tires installed on your vehicle

are rated because tires that are driven faster than their rated speed can fail suddenly.

Overloading tires can cause heat build-up, sudden tire failure, including a blowout and

sudden deflation and loss of control.

Temperature grades apply to tires that are properly inflated and not over- or underinflated.

Winter tires

Please first read and note the introductory information and heed the WARNINGS

Winter tires improve the handling characteristics of your vehicle significantly when driving under wintry
road conditions. Summer tires have less traction on snow and ice because of their design (width,
rubber composition, tread design). Volkswagen strongly recommends that you always have winter
tires or all-season tires installed on all 4 wheels on your vehicle, especially when winter road condi-
tions are expected. Winter tires also improve the vehicle's braking performance and help reduce
stopping distances during winter weather. Volkswagen recommends installing winter tires once tem-
peratures are below +45 °F (+7 °C).

Winter tires are no longer suitable for winter driving once the tread pattern is worn down to a depth of
3/16 in (4.8 mm). In addition, winter tire performance decreases with age – independent of the tread
profile depth.

When using winter tires:

  Obey state and country-specific legal requirements.
  Install winter tires on all 4 wheels.
  Use winter tires only under wintry road conditions.
  Only use winter tires with dimensions approved for the vehicle.
  Use only winter tires of the same tire belt design, the same dimensions (tread circumference), and

the same tread design.

Follow speed restrictions according to the winter tire's speed rating code letter

⇒ .

Speed restrictions

Winter tires are certified up to a top speed identified by speed rating code letters on the sidewall

⇒

Tire labeling.

In appropriately equipped vehicles, the speed warning can be set and changed in the Infotainment
system by pressing the

button followed by the

and Tires function keys

⇒ Menu and system

settings (SETUP).

Top speed rating and tire inflation pressure for V winter tires depend on the engine installed in your
vehicle. Be sure to ask you authorized Volkswagen dealer or authorized Volkswagen Service Facility
about the maximum permissible speed and the required tire inflation pressure for the winter tires that
you plan to use.

WARNING

Driving faster than the maximum speed for which the winter tires on your vehicle were de-
signed can cause sudden tire failure including a blowout and sudden deflation, loss of con-
trol, crashes and serious personal injuries.

Winter tires have a maximum speed rating that may be lower than your vehicle's maximum

speed.

Never drive faster than the maximum speed for which the winter tires installed on your

vehicle are rated because tires that are driven faster than their rated speed can fail suddenly.

Never exceed the maximum load rating for the winter tires installed on your vehicle.

Install summer tires promptly in the spring. Summer tires offer better handling characteristics for

temperatures above +45 °F (+7 °C). They are quieter, do not wear as quickly, and reduce fuel con-
sumption.

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) and recalibration through the Infotainment system.

If necessary, ask your authorized Volkswagen dealer or authorized Volkswagen Service Facility

about permissible winter tire dimensions.

Snow chains

Please first read and note the introductory information and heed the WARNINGS

Obey local regulations as well as the applicable speed limits when driving with snow chains.

Snow chains improve forward motion, traction and braking characteristics under wintry conditions.

Snow chains may be used only on the front wheels and only in tire and wheel combinations that
have been approved by Volkswagen.

Please contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility about
appropriate wheel, tire and snow chain dimensions.

If possible, use only chains with low profile links that are not thicker than 37/64 in. (15 mm) including
the tensioner.

Remove center hubcaps and decorative rim rings before installing snow chains

⇒ . However, for

safety reasons, caps must be installed on the wheel bolts. These are available from authorized
Volkswagen dealers and authorized Volkswagen Service Facilities.

Compact spare wheel

For technical reasons, snow chains cannot be used on the compact spare

⇒ Spare wheel or 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 to install the unidirectional tires so that they will run in the
proper direction. Volkswagen recommends installing the snow chains before mounting the wheel to
the vehicle.

WARNING

Using the wrong snow chains or installing snow chains improperly can cause accidents and
severe personal injuries.

  Always use the proper snow chains.
  Follow the installation instructions provided by the snow chain manufacturer.
  Never exceed the permissible speed limit when driving with snow chains.

NOTICE

Remove snow chains when roads are free of snow. Otherwise, the chains can damage the

tires, impair vehicle handling and can be quickly worn down.

Snow chains can scratch or damage wheel rims if they have direct contact with the rims.

Volkswagen recommends using coated snow chains.
