Maintenance
CAUTION!

vehicle. It will cause difficulty in cold starting and
may affect driveability.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door, on the left rear
quarter panel of the vehicle. If the gas cap is lost or
damaged, be sure the replacement cap is for use with this
vehicle.
After removing the gas cap, place the gas cap tether cable
over a hook on the inside of the fuel door. This keeps the
gas cap suspended away from and protects the vehicle’s
surface.
