oil level in the final gear case.NOTE:_ The oil level should be at the brim of the filler hole. _3. If the oil is below the brim of the filler hole,
add sufficient oil of the recommended type to
raise it to the correct level.CAUTION:_ Be sure no foreign material enters the final
gear case. _4. Install the oil filler bolt, and then tighten it to
the specified torque.

The brake fluid reservoir is located under the
hood. (See pages 8-17–8-19 for hood opening
and closing procedures.)
Observe these precautions:

When checking the fluid level, make sure the
top of the brake fluid reservoir is level.


Use only the recommended quality brake fluid.
Otherwise, the rubber seals may deteriorate,
causing leakage and poor braking perfor-
mance.


Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor braking performance.


Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock. Recommended brake fluid: DOT 4
