Volkswagen Tiguan Owners Manual:  Introduction to the subject

In this chapter you will find information on the following subjects:

⇒ Gasoline 

⇒ Gasoline additives 

The correct fuel grade for your engine is shown on a sticker located on the inside of the fuel filler flap ⇒ Fig. 153 .

Bad or poor quality fuel reduces operating performance, efficiency and service life of the engine. If you notice any symptoms like rough engine idle or performance or “bucking”, immediately reduce the vehicle speed, accelerate slowly and keep the engine speed in the middle of the rpm range. Avoid high rpm and rapid acceleration. If these symptoms should appear right after refueling, switch off the engine. In both cases contact an authorized Volkswagen dealer or an authorized Volkswagen service facility to have the engine checked.

Improper refueling or handling of fuel can cause fire, explosion, and severe burns.
  • Fuel is highly explosive and flammable and can cause severe burns and other injuries.
  • Heed applicable safety warnings and obey local fuel handling regulations.
  • Always make sure the fuel cap is screwed on all the way. This keeps fuel from spilling out and from evaporating.
  • Failure to shut the engine off while refueling and/or to insert the pump nozzle fully into the vehicle's filler neck could cause fuel overflow and fuel spray. Fuel spray and overflowing fuel are dangerous because they can cause fire or serious injury.
  • For safety reasons, the engine must be turned off when refueling.
  • 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. Static electricity can cause sparks that can ignite fuel vapors released during refueling.
