56 SERVICING AND MAINTENANCE
Please note that it is the owner's responsibility to
maintain the proper level of protection against
freezing according to the temperatures occurring
in the area where the vehicle is operated.
NOTE:

Mixing coolant types is not recommended and
can result in cooling system damage. If HOAT
and OAT coolant are mixed in an emergency,
have an authorized dealer drain, flush, and refill
with OAT coolant (conforming to MS.90032) as
soon as possible.

Low pressure expansion bottles for power elec -
tronics and battery cooling require a special tool
for removing the cap from the expansion bottle.
For the battery coolant bottle, it is important to
not add coolant if level is low. The vehicle should
be taken to an authorized dealer for proper
servicing of the battery coolant loop if this
should occur.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that engine
coolant will return to the radiator from the coolant
expansion bottle/recovery tank (if equipped).
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant is a regulated
substance requiring proper disposal. Check with
your local authorities to determine the disposal
rules for your community. To prevent ingestion
by animals or children, do not store ethylene
glycol-based coolant in open containers or allow it
to remain in puddles on the ground, clean up any
ground spills immediately. If ingested by a child or
pet, seek emergency assistance immediately.
Engine Coolant Level — 2.0L
CAUTION!
Use only high purity water such as deionized, or
distilled water when mixing the water/ coolant
(antifreeze) solution for the engine, battery or high
voltage electronics cooling systems. The use of
lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
WARNING!

Do not open a hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.

Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
