Introduction
Your vehicle runs on compressed natural gas (CNG), a highly
pressurized version of the same clean-burning natural gas used in
many homes and businesses.
Your vehicle operates and performs like a gasoline-powered
vehicle. However, there are a few differences you should be aware
of. In addition to reading your vehicle’s owner’s manual, please
read this supplement carefully to understand the operation and
unique features of your vehicle.
You will find important safety information in this supplement and
in the owner’s manual. This information alerts you to potential
hazards that could hurt you or others. Please read it carefully.
CNG (Compressed Natural Gas), Your Vehicle’s
Fuel
The main component of CNG (Compressed Natural Gas) is
methane. It is a highly flammable colorless gas that is used in
home appliances such as kitchen stoves and water heaters.
The CNG in your vehicle is stored under high pressure. The system
is designed to hold gas at the maximum of
3
,600 psi/
24
,800 kPa,
and you should never smell gas or hear a hissing sound unless you
are refueling. If you smell gas or hear a hissing sound at any other
time, shut down the CNG system immediately.
