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 Whenever stalled or stopped for repair, move the vehicle a safe distance off the road, stop
the engine, turn on the emergency flashers, and use other warning devices to warn
approaching traffic.
x Never park the vehicle in areas where the hot catalytic converter and exhaust system can
come into contact with dry grass, brush, spilled fuel, oil, or other material that can catch fire.
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.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
High Intensity Discharge (HID) headlights provide bright, uniform lighting to help you see and be
seen. The light comes from an electric arc between two electrodes in the gas-filled bulb. Over time, the
electrodes can wear down and the gap between them will get wider. The HID lamp’s control unit then
increases the voltage to keep the arc’s brightness constant. However, the commonly called “Xenon”
bulbs will also ultimately burn out. Before they burn out, HID lamps can flicker. A message will then
appear in the MFI. This is your reminder to see an authorized Volkswagen dealer or an authorized
Volkswagen Service facility to check the headlights.

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.

Indicator lights and fuel gauge
Refueling
Fuel capacities
Refueling checklist
The fuel filler flap is located on the rear right side of the vehicle.
More information:
x Exterior views
x Fuel
x Preparations for working in the engine compartment
WARNING
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe
burns.
x Always make sure that the fuel filler cap is screwed on all the way. This helps keep fuel
from spilling out or evaporating.
x Fuel is highly flammable and explosive; it can cause severe burns and other severe
injuries.
x Failure to shut the engine off while refueling and/or to insert the pump nozzle all the way
into the fuel filler neck can cause fuel to overflow and to spray out. Fuel spray and
overflowing fuel are dangerous because they can cause fire and serious personal injury.
x During refueling, the engine and the ignition must be switched off for safety reasons.
x Never use a cellular telephone, CB radio, or other radio equipment while refueling. The
electromagnetic radiation can cause sparks that can ignite fuel vapors and cause a fire.
x Never get back into your vehicle while refueling. If in exceptional circumstances you must
get back in your vehicle while refueling, make certain that you close the door and touch metal
to discharge static electricity before touching the filler nozzle again. This helps avoid the
build-up of static electricity, which can cause sparks that can ignite fuel vapors released
during refueling.
x Never smoke or have an open flame (or sparks, cigarettes, or other smoldering objects)
anywhere in or near your vehicle when refueling or filling a portable fuel container.
x Follow all safety instructions and procedures that apply at the service station where you
refuel.
x Never spill fuel in the vehicle or the luggage compartment.

Checklist
If you are uncertain in any way, have the work done by an authorized Volkswagen dealer or
authorized Volkswagen Service Facility. Serious personal injury may result from improperly performed
work. Make sure that you check the following items regularly. The best thing is to check them every
time you refuel:
d Windshield washer fluid level
d Engine oil level
d Engine coolant level
d Brake fluid level
d Tire pressure
d Vehicle lighting necessary for driving safety:
– Turn signals
– Low beams and high beams
– Taillights
– Brake lights
– License plate lights
