Catalytic silencer

The vehicle has a silencer with a "platinum - palladium - rhodium three-way" metal
catalytic converter.
This device oxidises the CO (carbon monoxide) producing carbon dioxide, and the
UHC (unburned hydrocarbons) producing water vapour and reduces NOx (nitrogen
oxide) producing oxygen and nitrogen present in the exhaust fumes.
DO NOT PARK THE VEHICLE NEAR DRY BRUSHWOOD OR IN PLACES EASILY
ACCESSIBLE BY CHILDREN BECAUSE THE CATALYTIC CONVERTER REA-
CHES HIGH TEMPERATURES DURING VEHICLE OPERATION; FOR THIS REA-
SON, PAY UTMOST ATTENTION AND DO NOT TOUCH IT UNTIL IT HAS
COMPLETELY COOLED DOWN.
