Filling the fuel tank
CAUTION:
Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
1. Open the hood and remove the front
storage compartment, to check the fuel
level. (See page 2-19 for front storage
compartment.)
2. Open the fuel tank filler cap, and slowly
add fuel to the fuel tank.
3. Stop filling when the fuel just reaches the
bottom of the filler tube on the fuel tank.
Do not fill into the filler tube, because
fuel could spill out.
Fuel tank capacity:
Total: 60 L (15.9 US gal, 13.2 Imp gal)
Reserve: 10 L (2.64 US gal, 2.20 Imp gal)
