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 noz-zles.
x Always stop refueling once the pump nozzle switches off so that the tank does not over-flow.
NOTICE
x It is your responsibility to put the right fuel in your vehicle and any damage that results from using the wrong fuel is not covered under the Emissions warranties or any other Volkswagen Limited Warranty.
x If you put any amount of the wrong 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 pre-vent leaks and serious damage.
NOTICE
Never force a fuel nozzle in the diesel misfueling guard. Forcing a fuel nozzle in the misfueling guard can damage it so that it can no longer help prevent misfueling.
x If you have problems inserting a diesel fuel nozzle, please check to make sure you are using the right kind of diesel fuel.
x If you must refuel with a non-standard diesel fuel nozzle, an adapter is available from Volkswagen to allow refueling. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. Only use an adapter approved by Volkswagen for your vehicle.
x Remember that the nozzle on a portable fuel container will generally not open the misfueling guard. If you must refuel with a portable fuel container in an emergency, you can pour diesel fuel very slowly from a portable container into the fuel filler neck of your vehicle. The fuel will flow slowly past the misfueling guard and into the tank.

Warning and indicator lights

NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
AdBlue information

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 work-shop. 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 re-sult 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 escap-ing 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 push-button start, 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 ⇒  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 elec-trocution, 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 elec-tronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the engine compart-
ment ⇒  Cleaning the engine compartment.
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 rotat-ing 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
Additional materials in the engine compartment such as blankets can interfere with the oper-ation of the engine and can cause fires, which can lead to serious injuries.
x Never cover the engine with blankets or other materials.

Closing the engine hood
x Lift the hood slightly ⇒ .
x Take out the hood support and clamp it in place in its bracket ⇒ fig. 163 A.
x Lower the engine hood by hand until it is about 8 in. (20 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.
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 wipers are switched off and 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 vehi-cle.
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.

The following information applies to vehicles without an engine coolant temperature gauge. If your
vehicle is equipped with an engine coolant temperature gauge in the instrument cluster, see ⇒  Warn-ing light and engine coolant temperature gauge.
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.
The following table explains what to do if the engine coolant temperature warning light ~ does not go out a few seconds after the engine is started or starts flashing while driving.
