Engine coolant
Engine coolant
The high-pressure cooling system
has a reservoir filled with year
round antifreeze coolant. The reser
voir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli
mate.
Radiator/Inverter cap
Never attempt to remove the radia
tor or inverter cap while the engine
is operating or hot. Doing so might
lead to cooling system and engine
damage and could result in serious
bodily injury from escaping hot cool
ant or steam.
Recommended coolant
When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the
factory. An improper coolant mix
ture can result in serious malfunc
tion or damage.
䳜 Do not use alcohol or methanol
coolant or mix them with the
specified coolant.
䳜 Do not use a solution that con
tains more than 60% antifreeze
or less than 35% antifreeze,
which would reduce the effective
ness of the solution.
䳜 The cooling circuit of a vehicle
equipped with a heat pump sys
tem may freeze in extremely low
temperature when the concen
tration of the antifreezing liquid is
below 45%.
For mixture percentage, refer to the
following table.
Radiator cap
Do not remove the
radiator cap when
the engine and radi
ator are hot. Scalding hot coolant
and steam may blow out under
pressure which may result in serious
injury.
