Before Driving
Fuel and Emission
Fuel-Filler Cap
To remove the fuel- ller cap, turn it
counterclockwise.
Attach the removed cap to the inner side
of the fuel lid.
To close the fuel- ller cap, turn it
clockwise until a click is heard.
CAUTION
If the check fuel cap warning light
illuminates, the fuel-fi ller cap may not
be properly installed. If the warning
light illuminates, park your vehicle
safely off the right-of-way, remove the
fuel-fi ller cap and reinstall it correctly.
After the cap has been correctly
installed, the fuel cap warning light
may continue to illuminate until a
number of driving cycles have been
completed. A drive cycle consists of
starting the engine (after four or more
hours with the engine off ) and driving
the vehicle on city and highway roads.
Continuing to drive with the check
fuel cap warning light illuminated
could cause the check engine light to
illuminate as well.
