Maintenance
Recommended coolant
• When adding coolant, use only
distilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory.
• An improper coolant mixture can
result in severe malfunction or
engine/ hybrid system damage.
• The engine in your vehicle has alu-
minum engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.
• Do not use alcohol or methanol
coolant or mix them with the spec-
ified coolant.
• Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated while driv-
ing.
1. Check if the coolant cap label
is straight In front.
