Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the reading should rise to
about the middle of the gauge. In
severe driving conditions, such as
very hot weather or a long period of
uphill driving, the reading may rise
into the upper half of the gauge. If it
reaches the red (Hot) mark, pull
safely to the side of the road. See
page 359 for instructions and
precautions on checking the engine
cooling system.

Check Fuel Cap Message
Your vehicle's onboard diagnostic
system will detect a loose or missing
fuel fill cap as an evaporative system
leak. The first time a leak is detected
a ''CHECK FUEL CAP'' message
appears on the information display.
Turn the engine off, and confirm the
fuel fill cap is installed. If it is, loosen
it, then retighten it until it clicks at
least once. The message should go
off after several days of normal
driving once you tighten or replace
the fuel fill cap. To scroll to another
display, press the SEL/RESET
button. The ''CHECK FUEL CAP''
message will appear each time you
restart the engine until the system
turns the message off.
