on for approximately up to 90 seconds. This
delay is initiated when the ignition is turned off
while the headlight switch is on, and then the
headlight switch is cycled off. Headlight delay
can be canceled by either turning the headlight
switch on then off, or by placing the ignition in
the ON/RUN position.

tive outside light bulb. If an indicator fails to light when the lever is moved, it would suggest
that the indicator bulb is defective.

6. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition is in the ON/
RUN position.
 The fuel pump symbol points
to the side of the vehicle where
the fuel door is located.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information. 7. Temperature Gauge
The gauge pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The gauge pointer will likely indicate a higher temperature when driving in hot
weather, up mountain grades, or when
towing a trailer. It should not be allowed
to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealer for service if your vehicle
overheats. If you decide to look under the
hood yourself, see “Servicing And
Maintenance.” Follow the warnings under the
Cooling System Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the
temperature gauge reads “H,” pull over and
stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H,” turn the engine off
immediately and call an authorized dealer for
service.
