Volkswagen Touran Owners Manual: Underseal

First read and observe the introductory information and safety warnings 

The underside of the vehicle is coated to protect it from corrosion and damage. The protective coating on the underside of the vehicle could be damaged when driving. Volkswagen recommends therefore that the protective coating on the underside of the vehicle and on the running gear should be checked regularly and repaired if necessary.

CAUTION

• Never apply underseal or anti-corrosion coatings to the exhaust pipes, catalytic converter, heat shields or other vehicle components that become hot.
