2020 VOLKSWAGEN TIGUAN overheating

The refill bottle must be disposed of in accordance with regulations governing the protection
of the environment.
Catalytic converter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
To help ensure long-term functionality in the exhaust system and the catalytic converter:
•Use unleaded petrol only ⇒ Fuel types and refuelling.
•Do not allow the fuel tank to run completely empty.
•Do not overfill engine oil ⇒ Engine oil.
•Do not tow start the vehicle. Use jump leads ⇒ Jump starting.
If you notice misfiring, uneven running or loss of power when the vehicle is moving, reduce speed
immediately. The vehicle should be inspected at the nearest qualified workshop
⇒ Troubleshooting. If this happens, unburnt fuel can enter the exhaust system and escape into the
atmosphere. The catalytic converter can also be damaged by overheating.
The emissions may have a sulphur-like smell even if the emission purification system is
working properly.
Particulate filter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Function
The particulate filter filters out soot particles in the exhaust gas. Observe the following points to
ensure that the exhaust purification system will work properly for a long time:
AdBlue is an irritant and corrosive fluid that can damage the skin, eyes and breathing
passages upon contact.
•Always observe the instructions for use when using AdBlue. If containers are used
according to the instructions, it is unlikely that a user will come into contact with
AdBlue.
•AdBlue must be kept in the closed original container. Never use empty food
containers, bottles or other containers for this purpose.
•Always store in a safe place out of reach of children.
•If AdBlue gets into the eyes, immediately rinse the eyes with plenty of water for at
least 15 minutes and consult a doctor.
•If AdBlue gets onto the skin, immediately wash the area with plenty of water for at
least 15 minutes and consult a doctor if the skin becomes irritated.
•If AdBlue is swallowed, immediately rinse the mouth out with lots of water for at least
15 minutes. Do not induce vomiting unless instructed to do so by a doctor. Seek
medical assistance immediately.

Overfilling AdBlue may damage the tank system and the vehicle.
•Do not fill with more than the maximum refill quantity indicated on the instrument
cluster display.
•Remove any spilt AdBlue as quickly as possible with a damp cloth and plenty of cold
water.
•If the AdBlue has already formed crystals, use warm water and a sponge to remove.
NOTICE

®
®
Improper use of AdBlue may cause damage to the vehicle that is not covered by the
warranty.
•Only use AdBlue that complies with the standard ISO 22241-1.
•Do not mix with water, fuel or additives.
•Never fill AdBlue in the diesel tank.
•Do not transport the refill bottle in the vehicle habitually. The bottle may develop a leak
following changes in temperature and damage and the AdBlue may damage the
vehicle interior.

•Always check the tyre pressure when the tyres are cold. The specified tyre pressure applies to
cold tyres. Tyre pressure is always higher in warm tyres than it is in cold tyres. For this reason,
never reduce the pressure in warm tyres to adjust the tyre pressure.
•Always adjust the tyre pressure to the load level ⇒ Fig. 236\b.
•After adjusting the tyre pressures, always screw the caps onto the valves and observe the
information on the tyre monitoring system ⇒ Tyre monitoring systems.
•Always use the tyre pressure specified on the sticker. Never exceed the maximum tyre pressure
which is given on the sidewall of the tyre
Underinflated tyres will result in increased fuel consumption.
Tread depth and wear indicators
Fig. 238 Tyre tread: wear indicators.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Tread depth
In most countries, the minimum tread depth required by law is 1.6 mm (measured in the tread
grooves next to the tread wear indicatorsyfQRWHDQ\FRXQWU\VSHFLILFUHJXODWLRQV7KHW\UHVVKRXOG
have the same tread depth, at the minimum on each axle ⇒.
Observe any country-specific legal requirements relating to the permissible minimum tread depths
for winter and all-year tyres ⇒ Winter tyres.
Tread wear indicator in tyres
The tread wear indicators show if a tyre is worn down. The tyre must be replaced at the latest when
the tread depth is just down to the tread wear indicator.
The bottom of the tyre tread has 1.6 mm high tread wear indicators ⇒ Fig. 238. Markings on the
tyre sidewall indicate the position of the tread wear indicators ⇒ Fig. 238.
Incorrect tyre pressure may cause the tyre to suddenly lose pressure or burst while the
vehicle is in motion. This can cause serious accidents and fatal injuries.
•If the tyre pressure is too low, it is possible that the tyre temperature will increase to
such an extent when driving that the tread peels off and the tyre bursts.
•Fast speeds or overloading of the vehicle can cause overheating, sudden tyre damage
including tyre bursts and ripping of the tread surface and thus to a loss of control of
the vehicle.
•If the tyre pressure is too low, the tyres will wear prematurely and the car will not
handle well.
•Check tyre pressures regularly, at least once a month, and before every long journey.
•All tyres must have the correct tyre pressure to suit the vehicle load.
•Never reduce excess pressure when the tyres are warm.
WARNING
•When attaching the tyre pressure gauge, ensure that you do not position it at an angle
to the valve stem. This can damage the tyre valve.
•Always make sure the valve caps are completely screwed on while driving.
