●Be careful not to spill engine oil on the vehicle components.
●Avoid overfilling, or the engine could be damaged.
●Check the oil level on the dipstick every time you fill the oil.
●Be sure the engine oil filler cap is properly tightened.

Maintenance and care
■Coolant selection
Only use SUBARU Super Coolant or similar high-quality ethylene glycol-
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-
life hybrid organic acid technology.
SUBARU Super Coolant is a mixture of 50% coolant and 50% deionized
water. (Enabled: -31°F [-35 °C])
For more details about engine cool ant, contact your SUBARU dealer.
WARNING
■When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
CAUTION
■When adding engine coolant
Coolant is neither plain water nor stra ight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it damaging parts or paint.

5-2. Steps to take in an emergency
■Overheating
If you observe the following, your vehicle may be overheating.
●The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
●Steam is coming from under the engine hood.
WARNING
■To prevent an accident or injury when inspecting under the engine
hood of your vehicle
●If steam is seen coming from under the engine hood, do not open the
engine hood until the steam has subsided. The engine compartment may
be very hot, causing serious injury such as burns.
●Keep hands and clothing away from the fan and other belts while the
engine is running.
●Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( →P. 422)
Have the vehicle checked at the nearest SUBARU dealer as soon
