PART 4: CONTROLS AND DISPLAYS GAUGES
(R10/06) Y53-6007 – 47 –
WARNING! Do not remove a fuel tank cap near
an open flame. Hot fuel vapors are combusti-
ble and can cause an explosion or fire result-
ing in injury or death.
The fuel gauge shows the approximate amount of fuel in
the fuel tanks. You will want to keep your fuel tanks at
least half full to reduce condensation of moisture in the
tanks. This moisture can damage your engine.
WARNING! Carrying additional fuel containers
in your vehicle is dangerous. Full or empty,
they may leak, explode, and cause or feed a
fire. Don’t carry extra fuel containers - even
empty ones.
Warning Lights and Buzzers
WARNING! Ignoring a warning light or buzzer
could lead to an accident. These signals tell
you something is wrong with your vehicle. It
could be a failure in an important system,
such as your brakes. Never ignore a warning
signal. Have the appropriate system checked
right away.
