WARNING!
● Y
ou or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator
.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator has
had time to cool. Never open a cooling system
pressure cap when the radiator or coolant bottle is
hot.
● Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised.
The fan starts automatically and may start at any
time, whether the engine is running or not.
● When working near the radiator cooling fan,
disconnect the fan motor lead and turn the
ignition to the OFF mode. The fan is temperature
controlled and can start at any time the ignition is
in the ON mode.
Coolant Checks
Check the traction system coolant (antifreeze)
protection ev
ery 12 months (before the onset of
freezing weather, where applicable). If the traction
system coolant is dirty, the system should be drained,
flushed, and refilled with fresh OAT coolant (conforming
to MS-12106) only by an authorized dealer. Check the
front of the A/C condenser for any accumulation of
bugs, leaves, etc. If dirty, clean by gently spraying water
from a garden hose vertically down the face of the
condenser.
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add coolant
pr
operly. Failure to fill these systems properly could
lead to severe internal traction system damage. If any
coolant is needed to be added to the system please
contact an authorized dealer.
If the traction system coolant (antifreeze) is dirty or
contains visible sediment, have an authorized dealer
clean and flush with OAT coolant (conforming to
MS.90032).

NOTE:
● Mixing of motor coolant (antifreeze) other than
specified Organic Additive Technology (OAT) motor
coolant, may result in motor damage and may
decrease corrosion protection. OAT motor coolant
is different and should not be mixed with Hybrid
Organic Additive Technology (HOAT) motor coolant
or any “globally compatible” coolant. If a non-OAT
motor coolant is introduced into the cooling system
in an emergency, the cooling system will need to be
drained, flushed, and refilled with fresh OAT coolant
(conforming to MS.90032), by an authorized dealer
as soon as possible.
● Do not use water alone or alcohol-based motor
coolant products. Do not use additional rust
inhibitors or antirust products, as they may not be
compatible with the radiator motor coolant and may
plug the radiator.
● This vehicle has not been designed for use
with pr
opylene glycol-based motor coolant. Use
of propylene glycol-based motor coolant is not
recommended.
● Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal motor damage. If any coolant
is needed to be added to the system please contact
an authorized dealer.
Adding Coolant
The vehicle has been built with an improved traction
system coolant (OAT coolant conforming to MS.90032)
that allows extended maintenance intervals. This
traction system coolant (antifreeze) can be used
up to 10 years or 150,000 miles (240,000 km)
before replacement. To prevent reducing this extended
maintenance period, it is important to use the same
traction system coolant (OAT coolant conforming to
MS.90032) throughout the life of your vehicle.
NOTE:
● 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.
● If any coolant is needed to be added to the system,
please contact an authorized dealer.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
traction system coolant (antifreeze), and to ensure that
