2020 Ram ProMaster City engine overheat

254 SERVICING AND MAINTENANCE
(Continued)
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to ensure proper catalyst
operation and prevent possible catalyst damage.
NOTE:
Intentional tampering with emissions control systems can
result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer's specifications, should
be obtained immediately.
WARNING!
• Exhaust gases can injure or kill. They contain carbon monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can eventu -
ally poison you. To avoid breathing CO, refer to “Safety
Tips” in “Safety” for further information.
• A hot exhaust system can start a fire if you park over materials that can burn. Such materials might be grass
or leaves coming into contact with your exhaust system.
Do not park or operate your vehicle in areas where your
exhaust system can contact anything that can burn.
CAUTION!
• The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effective -
ness of the catalyst as an emissions control device and
may seriously reduce engine performance and cause
serious damage to the engine.
• Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the
event of engine malfunction, particularly involving
engine misfire or other apparent loss of performance,
have your vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction could
cause the converter to overheat, resulting in possible
damage to the converter and vehicle. CAUTION!
