WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to
break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
x Park the vehicle at a safe distance from moving traffic and where no part of the hot cata-
lytic converter and exhaust system can come into contact with flammable materials under the
vehicle, such as dry grass, brush, spilled fuel, etc.
x A broken down vehicle presents a high accident risk for itself and others. Switch on
emergency flashers and set up a warning triangle to warn oncoming traffic.
WARNING
Roads and bridges may be dangerously icy even if the outside air temperature is above freez-
ing.
x If you use the outside temperature display to tell you about frost conditions, remember
that roads can even ice over at temperatures above +39 °F (+4 °C). Always remember: even if
the “snowflake symbol” (icy road warning) is not displayed, there could still be black ice on
the road.
x Never rely exclusively on the outside temperature display.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
The instrument cluster displays and their arrangement may vary depending on the vehicle model
and engine. For displays without warning and information messages, malfunctions are only signaled
with indicator lights.
If there are multiple warning messages, the symbols are displayed for several seconds in order of
importance. The symbols are displayed until the cause has been corrected.

WARNING
Driving when the brake booster is not working increases stopping distances and can cause
accidents and serious personal injuries.
x Never let the vehicle coast when the engine is switched off.
x If the brake booster is not working (such as when the vehicle is being towed), a lot more
pedal force is needed to slow down and stop.
NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to
brake. Constant pressure on the brake pedal can make the brakes overheat. Riding the brakes
will substantially reduce braking performance, increase stopping distance, and can cause
complete brake system failure.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and
shift into lower gear (manual or automatic transmission). This will let the vehicle use engine
braking and reduce the load on the brakes. Otherwise, the brake system could overheat and
possibly fail. Only use the brakes when you need them to slow the vehicle down more or to
stop.
When the front brakes are serviced, you should have the rear brake pads inspected at the same
time. The wear of all brake pads should be visually checked regularly. The best way to check for brake
pad wear is to have your authorized Volkswagen dealer or authorized Volkswagen Service Facility
visually inspect the pads through the openings in the wheel rims or from underneath the vehicle. If
necessary, the wheels can be taken off for a more thorough inspection.
Braking assistance systems

Brake fluid specifications
Volkswagen has developed a special brake fluid that is optimized for the brake system in your
Volkswagen. Volkswagen recommends that you use brake fluid that expressly conforms to quality
standard VW Standard 501 14 for optimum performance of the brake system. 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 purchased from your authorized
Volkswagen dealer or authorized Volkswagen Service Facility.
If this special brake fluid is not available you may – under these circumstances – 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 expressly complies with VW
Standard 501 14 for optimum brake system 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 incorrect brake fluid.
x Check the brake system and brake fluid level regularly.
x Always change the brake fluid according to the service schedule in your
⇒ Booklet Warranty and Maintenance.
x Hard braking with old brake fluid may cause vapor lock. Vapor lock reduces braking
performance, increases stopping distances and can even cause total brake failure.
x 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 fluid that conforms to U.S. Standard FMVSS 116 DOT 4 requirements.
x Using another brake fluid, or one that is not of high quality, can impair the function of the
brake system and reduce its effectiveness. 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.
x The brake fluid must be new.

NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
Driving for a longer period of time on rough roads or with a dynamic and sporty style can make
the TPMS system temporarily unavailable. The indicator light will come on, signaling a malfunction, but
will go out again once the road condition or driving style changes.
Applicable only in the United States
Tire Pressure Monitoring System (TPMS)

Fig. 135 Display screen in the instrument cluster: Current tire pressures in psi.

The Tire Pressure Monitoring System may not react at first or may not react at all when you are driving
in a sporty manner, or on snow-covered or unpaved roads, when you are driving with snow chains, or
in certain other situations. A change in the tread circumference of a tire is signaled by the Tire
Pressure Monitoring System indicator in the instrument cluster (telltale).
The tire pressure recommended for the tires originally installed on the vehicle is on a sticker on the
driver door jamb
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation
pressure 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
underinflated. 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. Underinflation 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 maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator 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 illuminated. 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 malfunctions 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 malfunction 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.
Resetting and recalibrating the benchmark tire pressure
Resetting the tire pressures in the Multi-function Display (MFI) resets the benchmark tire pressure
used by the TPMS to the current tire pressure in the tires based on the circumference of the tires.
To reset the reference tire pressure, switch on the ignition. In the MFI, navigate to the Settings
menu and select Tire pressure. Store and confirm the new tire pressures.
The recalibration must be performed each time the tire pressure in one or more tires has been
adjusted or after one or more tires has been changed, exchanged, or repaired. The new tire pressures
are stored in the system only after at least 20 minutes of normal driving.
If you have reset the benchmark tire pressure when your tires do not have the correct tire pressure,
this will prevent the TPMS from working properly. It may then give false warnings or may not give any
warning even if the tire pressure is too low.
For this reason, it is vital to make certain that all 4 tires are inflated to the correct pressure
when they are cold, before calibrating the system. Cold tire tires are tires that have not been driven
more than a couple of miles (kilometers) at low speed within the last 3 hours.
Recalibrate the system to reset the benchmark TPMS pressure in the following
situations:
x After installing tires on your vehicle that have recommended cold tire inflation pressures that are
different from the tires that were taken off.
x After any tire on your vehicle is removed and then remounted, even if the same tire and wheel rim
that were taken off are reinstalled (for instance, after repair).

Under- or over-inflation significantly shortens the service life of your tires and affects the handling of
the vehicle ⇒ . The correct tire pressure is very important, particularly when the vehicle is driven at
higher speeds. Incorrect tire pressure causes increased wear and even sudden tire failure and
blowouts.
Therefore, tire pressure should be checked at least once a month and always before long trips.
The specified tire inflation pressure applies to a cold tire. When tires are warm, the pressure will be
higher than when the tires are cold.
Do not reduce the tire pressure on warm tires to match the required cold tire inflation pressure. The
tire inflation pressure would then be too low and could cause sudden tire failure and blowout.
Checking tire inflation pressure
Always check the tire pressure only on “cold” tires when the vehicle has not been driven more than a
couple of miles (kilometers) at low speed within the last 3 hours.
x Check tire inflation pressure regularly and on cold tires. Check all the tires, including the compact
spare, if any. In colder climates tire pressure should be checked more often, but only when the tires
are cold. Always use an accurate tire pressure gauge.
x Adjust the tire pressure for heavy loads accordingly.
x After adjusting the tire inflation pressures, make sure to screw the valve caps back on; replace
missing valve caps immediately. Please read and heed the information on resetting the Tire Pressure
Monitoring System, if necessary
x Remember that the vehicle manufacturer, not the tire manufacturer, determines the correct tire
pressure for the tires on your vehicle. Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Inflate a spare wheel to the pressure specified for the vehicle's road wheels on the tire pressure label;
inflate a compact spare wheel to the 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
Incorrect tire pressure can cause a sudden tire failure or blowout, loss of control, collision,
serious personal injury, and even death.
x Always inflate tires to the recommended and correct cold tire pressure before driving off.
x 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.
x Excessive speed and/or overloading can cause heat build-up, sudden tire failure including
a blowout and sudden deflation 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 Regularly check tire inflation pressure, at least once a month, and also especially before a
long trip.
x 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
x Make sure not to jam the tire pressure gauge into the valve stem. Otherwise, you can
damage the tire valves.
x 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
