answer or respond to SOS system calls.
If the SOS Call system detects a malfunction, any of the
following may occur at the time the malfunction is
detected, and at the beginning of each ignition cycle:
 The overhead console lights located within the ASSIST
and SOS buttons will continuously illuminate red.
 The Device Screen will display the following message:
“Vehicle device requires service. Please contact an
authorized dealer.”
 Where applicable, an In-Vehicle Audio message will
state “Vehicle device requires service. Please contact
an authorized dealer.” Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop the SOS
Call system operation. These include, but are not limited
to, the following factors:

The ignition is in the OFF position
 The vehicle’s electrical systems are not intact
 The SOS Call system software and/or hardware are

Selection Of Coolant
For further information Úpage 396.
NOTE:
Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) engine
coolant, may result in engine damage and may
decrease corrosion protection. OAT engine coolant is
different and should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant or any
“globally compatible” coolant. If a non-OAT engine
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 engine
coolant products. Do not use additional rust inhibitors
or anti-rust products, as they may not be compatible
with the radiator engine coolant and may plug the
radiator.
 This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not recom -
mended.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact an
authorized dealer.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that
allows extended maintenance intervals. This engine
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 that you use the same engine coolant
(OAT coolant conforming to MS.90032) throughout the life
of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) engine coolant that meets the
requirements of the manufacturer Material Standard
MS.90032. When adding engine coolant:
We recommend using Mopar® Antifreeze/Coolant
10 Year/150,000 Mile (240,000 km) Formula OAT
that meets the requirements of the manufacturer
Material Standard MS.90032.
 Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032 and distilled water.
Use higher concentrations (not to exceed 70%) if
temperatures below −34°F (−37°C) are anticipated.
Please contact an authorized dealer for assistance.
 Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.
The use of lower quality water will reduce the amount
of corrosion protection in the engine cooling system.
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.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system, please contact an
authorized dealer.
 Mixing engine 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.
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.
