warning lights VOLKSWAGEN PASSAT 2013 B8 / 6.G Owner's Manual

When the ignition is switched on, several warning and indicator lights come on briefly for a function
check. They go out after a few seconds.
WARNING
Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control,
collision, serious personal injury, or even death.

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.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
If the ignition is switched on, an acoustic warning sounds when low tire pressure is detected. If a
system malfunction is detected, no acoustic warning sounds.
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 Canada and the United States

WARNING
Stale air causes driver fatigue and reduces alertness, which can cause accidents, collisions,
and serious personal injury.
x Never switch off the fan for a long time, because no fresh air will enter the passenger
compartment.

WARNING
Driving with a fuel tank that is almost empty can lead to stalling in traffic, a collision, and
serious personal injuries.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted,
especially when driving over bumps, across slopes, and up and down hills.
x Steering and braking assistance as well as ESC and related systems will not work if the
engine “sputters” or stalls due to lack of fuel.
x Always refuel when the tank is 1/4 full to reduce the risk of running out of fuel and stalling
in traffic.
NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x Never drive until the fuel tank is completely empty. The irregular fuel supply can cause the
engine to misfire. This allows unburned fuel to get into the exhaust system and damage the
catalytic converter or the diesel particulate filter.
The small arrow next to the gas pump symbol in the fuel gauge shows the side of the vehicle with
the fuel filler flap.

WARNING
The engine compartment of any motor vehicle is a potentially dangerous area and can cause
serious personal injury.
x Always use extreme caution when doing any work in the engine compartment. Always
follow commonly accepted safety practices and use common sense. Never risk personal
injury.
x Never perform any work in the engine compartment unless you know exactly how to carry
out the job and have the correct technical information and the correct tools.
x If you are uncertain about what to do, have the work performed by an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified
workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon)
headlights and H7 bulbs replaced by a qualified technician. Serious personal injury may
result from improperly performed work.
x Never open or close the engine hood if steam or coolant is escaping. Hot steam or coolant
can cause serious burns. Always wait until you no longer see or hear steam or coolant
escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood.
x Hot parts of the engine and the exhaust system will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P) (automatic) or
Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out
of range of the vehicle and that the vehicle cannot be started by depressing the starter
button.
– Always keep children and others away from the engine compartment and never leave
them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the
coolant expansion tank cap when the engine is hot. Hot coolant can spray out and cause
severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying
light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by
covering the cap with a large, thick rag.
x Never spill fluids on the engine or exhaust system when refilling. Spilling fluids onto hot
parts of the engine or exhaust system can cause a fire.
WARNING
High voltage systems in the engine compartment can cause electrical shocks or even
electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables.
The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or
being started:
– Never touch ignition cables. Never touch other components of the high voltage
electronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.

WARNING
Improper replacement of burned out headlights and other light bulbs can cause serious
personal injury.
x Stop! Always read and heed the WARNINGS before doing any work in the engine
compartment. The engine compartment of any motor vehicle is a potentially dangerous area,
and work in this area can lead to serious personal injury.
x HID – High Intensity Discharge (Xenon) headlights get power from a high voltage source
that can cause severe personal injury and even death if handled improperly.
x H7 bulbs and HID – High Intensity Discharge (Xenon) headlights are under high pressure
and can explode if handled improperly.
x Always let a burned out light bulb cool down before replacing it.
x Never replace a light bulb unless you are familiar with all of the necessary procedures. In
particular, never remove a headlight unless you know exactly how to carry out the job and
have the correct tools and light bulbs.
x If you are uncertain about what to do, have the work performed by an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified
workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon)
headlights and H7 bulbs replaced by a qualified technician.
x Do not touch the glass of light bulbs with your bare hands. Fingerprints left on the bulb
evaporate due to the heat when the bulb is switched on and cause the reflector to “cloud.”
x There are sharp edges on and around the headlight housing in the engine compartment
and the rear light housing. Wear hand protection if you replace bulbs.
NOTICE
After replacing a headlight bulb or other light bulb, always make sure that the rubber covers or
plastic caps have been properly and securely reinstalled to help prevent water from getting
into the electrical connections and headlight housing and damaging the electrical system.
