Recommended engine 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
incorrect coolant mixture can result
in serious malfunction or engine
damage.
• The engine in your vehicle has
aluminum 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 specified
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.
For mixture percentage, refer to the
following table.

Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of -35°C
(-31°F) and higher.
