2 Reserve tank cap
Open the reserve tank cap, and then drain
the coolant.
Install the reserve tank.
Clean the radiator with clean water to
remove any debris or rust.
Drain all water from the radiator.
Follow the steps below to fill with coolant.
The coolant quantity, including the reserve
tank, is 3.1 dm
3
(3.1 L).
Install the drain plug.
Supply clean water and antifreeze into the
radiator up to the radiator cap opening.
Close the radiator cap.
Supply clean water and antifreeze into the
reserve tank up to the "FULL" mark.
Close the reserve tank cap.
Start the engine, and then idle for several
minutes to bleed air from the system.
Stop the engine, and then allow the radiator
to cool.
Check if the coolant level in the reserve tank
is between "FULL" and "LOW", and then
supply coolant if necessary.
Close the hood.

Important
When you change the hydraulic oil, be sure to
drain it into a bowl and discard it in
accordance with local laws and regulations.
Important
If the hydraulic oil emulsifies or if it becomes
even slightly less transparent, change the oil
immediately.
Important
Use Shell Tellus S2M46 (or equivalent) as
hydraulic oil.
In case of an equivalent, consult
Characteristics of Hydraulic Oil and use
hydraulic oil whose characteristics are
superior to those of the specific hydraulic oil.
Especially regarding kinematic viscosity and
viscosity index, use of hydraulic oil whose
figures are less than those of the specified
hydraulic oil will cause a malfunction in the
hydraulic circuit.
