PRECAUTIONS FOR LOW TEMPERATURE
If the temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze, so do as follows.
FUEL AND LUBRICANTS
Replace fuel and oil in each component with ones of lower viscosity.
For the details on the specified viscosity, see the section of "USE OF FUEL, COOLANT AND LUBRICANTS
ACCORDING TO AMBIENT TEMPERATURE (PAGE 4-14)".
COOLANT
WARNING
Keep antifreeze fluid away from open flames. Never smoke when using antifreeze.
NOTICE
Never use methanol, ethanol or propanol based antifreeze.
Avoid using any leak-preventing agent, regardless if it is sold separately or in antifreeze.
Do not mix one brand of antifreeze with a different brand.
For the timing of engine cooling water replacement and mixing ratio of antifreeze, see the section of "CLEAN INSIDE
OF COOLING SYSTEM (PAGE 4-28)".
Use a Permanent Antifreeze (ethylene glycol mixed with corrosion inhibitor, antifoam agent, etc.) meeting the
standard requirements as shown below. With permanent antifreeze, no change of coolant is required for a year. If
it is doubtful that an available antifreeze meets the standard requirements, ask the supplier of that antifreeze for
information.
Standard requirements for permanent antifreeze
