OPENING HOOD

After raising the hood, insert the S shaped safety hook through

two matching holes in the prop channels to prevent the hood

from falling accidentally.

To perform checks or services on components located in the engine compartment, you

will need to raise one or both of the hinged hood panels.

The right-hand hood side can be raised to perform most of all routine maintenance

such as checking or filling the radiator and engine oil. The left-hand side is used

for checking power steering fluid, servicing the fuel filter and filling the alcohol

evaporator reservoir.
