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
coola
nt level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli
-
mate.
CAUTION
Radiator/Inverter cap
Never attempt to remove the radia
-
tor or inverter cap while the motor
is operating or hot. Doing so might
lead to cooling system and motor
damage.
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 m
ethanol
coolant or mix them with the
specified coolant.
䳜 D
o 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
eq
uipped 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
