Maintenance Engine coolant
Engine coolant
The high-pressure cooling system has a
reservoir filled with year round anti
-
freeze coolant. The reservoir 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 climate.
僅 When the engine overheats from low
engine coolant, suddenly adding
engine coolant may cause cracks in
the engine. To prevent damage, add
engine coolant slowly in small quanti
-
ties.
僅 Do not drive with no engine coolant. It
may cause water pump failure and
engine seizure, etc.
Engine coolant reservoir cap
Never attempt to remove the
engine coolant reservoir cap
while the engine is operating or
hot. Doing so might lead to dam
-
age to the cooling system and engine,
and could result in serious bodily injury
from the escaping hot coolant or steam.
Recommended coolant
When adding coolant, use only deion
-
ized water or soft water for your vehicle
and never mix hard water in the coolant
filled at the factory. An improper coolant
mixture can result in serious malfunction
or damage.
僅 Do not use alcohol or methanol cool
-
ant or mix them with the specified
coolant.
僅 The engine in your vehicle has alumi
-
num engine parts and must be pro
-
tected by an ethylene-glycol with
phosphate based coolant to prevent
corrosion and freezing.
僅 Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
僅 The cooling circuit of a vehicle
equipped with a heat pump system
may freeze in extremely low tempera
-
ture when the concentration of the
antifreezing liquid is below 45%.
For mixture percentage, refer to the fol
-
lowing table.
Engine coolant reser
-
voir cap
Do not remove the
engine coolant reser
-
voir cap when the
engine and engine coolant reservoir are
hot. Scalding hot coolant and steam may
blow out under pressure which may
result in serious injury.
