2013 VOLKSWAGEN PASSAT Check engine

slightly with light pressure to open the misfueling guard. If the misfueling guard cannot be opened this
way, see the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility and
have the fuel system checked.
WARNING
Spilled fuel can cause fires, explosions, burns, and other severe injuries.
x Do not refuel from devices other than correct, undamaged standard diesel fuel pump
nozzles.
x Always stop refueling once the pump nozzle switches off so that the tank does not
overflow.
NOTICE
x It is your responsibility to put the right fuel in your vehicle and any damage that results is
not covered under the Emissions warranties or any other Volkswagen Limited Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
x Never force a fuel nozzle in the misfueling guard. If you have problems inserting a fuel
nozzle, first check to make sure you are using the correct diesel fuel. If you are, go to a pump
with the standard diesel nozzle. Forcing a fuel nozzle in the misfueling guard can damage it so
that it can no longer help prevent misfueling.

WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can
cause serious personal injury. Always remember that the radiator fan is temperature-
controlled and can come on suddenly even when the engine has been switched off for a while
and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks
from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the
high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in
rotating engine parts. Before starting any work remove your jewelry, take off your necktie,
tie back and cover your hair, and do not wear clothing that can hang down and get caught
in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a
check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools.
Objects left behind can cause malfunctions, engine damage, and even fires.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing
burns and other serious personal injuries!
x Do not smoke.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids
can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when
you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the
ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.
NOTICE
When changing or topping off fluids, make sure that you pour the fluids into the correct
reservoirs. Adding the wrong type of operating fluids will cause serious malfunctions and
engine damage.
Fluid leaks and spills are harmful to the environment. Regularly check the ground underneath
your vehicle for this reason. If you find spots of oil or other fluids, have your vehicle checked by your
authorized Volkswagen dealer or authorized Volkswagen Service Facility. Dispose of leaked operating
fluids properly.

WARNING
Disregarding the safety-related checklist may result in serious injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common
sense.
Opening and closing the engine compartment

Fig. 166 A: In the footwell on the driver side: Inside engine hood release lever. B: Above the radiator grille:
Outside engine hood release (under the hood).

Fig. 167 C: In the engine compartment: Bracket for hood support. D: Hood propped open.

Closing the engine hood
x Lift the hood slightly ⇒ .
x Take out the hood support and clamp it in place in its bracket C.
x Lower the hood by hand until it is about 1 ft. (30 cm) above its latch and then let it drop into place
to latch it. Do not push down on it afterwards!
If the hood does not close completely, open it again and close it properly.
When the hood is properly closed, you can see that it fits flush with the other body parts. The indicator
light in the instrument cluster will go out.
WARNING
If the hood is not closed properly, it could fly up and block your view while you are driving.
This can lead to a crash and serious personal injuries.
x After closing the engine hood, check that the hood release lever is properly latched into
the hood latch. The engine hood must be flush with the surrounding auto body parts.
x If you ever notice that the hood latch is not properly secured when the vehicle is moving,
stop at once and close it.
x Never let anyone get in the way of the hood when closing it.
NOTICE
x Make sure the windshield wiper arms are resting on the windshield before you open the
hood. Otherwise, the windshield wipers and the hood may be damaged.
x Always put the windshield wiper arms down against the windshield before driving the
vehicle.
NOTICE
Before opening or closing the engine hood, make sure there is enough room to do so, for
example when the vehicle is in a garage.

WARNING
Hot steam and hot engine coolant can cause serious burns.
x Never open the hood if you see steam or coolant escaping from the engine compartment.
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. Hot
components 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 ⇒ page 227.
– 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. Under some conditions, the ethylene
glycol in engine coolant can catch fire.
NOTICE
x Use distilled water only when adding coolant! All other types of water contain chemical
compounds that can cause extensive corrosion damage to the engine. This can even lead to
engine failure. If you have added non-distilled water, take the vehicle immediately to an
authorized Volkswagen dealer or an authorized Volkswagen Service Facility to have the
coolant system drained, flushed, and refilled completely with the proper coolant.
x Refill engine coolant only up to the top edge of the marked fill range . Excess engine
coolant may be forced out of the engine cooling system when it gets hot and cause damage.
x In the case of significant engine coolant loss, refill engine coolant only when the engine is
completely cooled down. Significant engine coolant loss is a sign of leaks in the cooling
system. Have the engine cooling system checked immediately by an authorized Volkswagen
dealer or an authorized Volkswagen Service Facility. Otherwise the engine may be damaged!
x When changing or topping off operating fluids, make sure that you pour the fluids into the
correct reservoirs. Serious malfunctions and engine damage can result if you pour operating
fluids into the wrong reservoir.
