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.
Checking the engine coolant level
When adding coolant, use only deion
-
ized water, distilled water or soft water
for your vehicle and never mix hard
water in the coolant filled at the factory.
僅 An incorrect coolant mixture can
result in severe malfunction or
engine/hybrid system damage.
僅 The engine in your vehicle has alumi
-
num engine parts and must be pro
-
tected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.
僅 Do not use alcohol or methanol cool
-
ant or mix them with the specified
coolant.
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.
WARNING
Make sure the engine coolant reservoir
cap is properly closed after refill or cool
-
ant.
Otherwise the engine could be over
-
heated while driving.
1. Check if the engine coolant reservoir
cap label is straight In front.
2. Make sure that the tiny protrusions
inside the engine coolant reservoir
cap are securely interlocked.
