CAUTION!
Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may
result in engine damage and may decrease
corrosion protection. Organic Additive Tech -
nology (OAT) engine coolant is different and
should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant
(antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) 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 autho -
rized dealer as soon as possible.Do not use water alone or alcohol-based
engine coolant (antifreeze) products. Do
not use additional rust inhibitors or antirust
products, as they may not be compatible
with the radiator engine coolant and may
plug the radiator.
CAUTION! (Continued)
This vehicle has not been designed for use
with propylene glycol-based engine coolant
(antifreeze). Use of propylene glycol-based
engine coolant (antifreeze) is not recom -
mended.

vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum) to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide good
performance.
If climatized or diesel Number 1 ULSD fuel is not available, and you are operating below (20°F/-6°C), in sustained
arctic conditions, Mopar Premium Diesel Fuel Treatment (or equivalent) is recommended to avoid gelling.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM specification D-975.
Pickup
models, and Chassis Cab models configured with optional B20 capability, are additionally compatible with 20%
biodiesel meeting ASTM specification D-7467.
Diesel Exhaust Fluid Mopar Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API Certified to the ISO 22241 standard.

MULTIMEDIA
UCONNECT SYSTEMS
For detailed information about your Uconnect
4/4C/4C NAV with 8.4-inch or 12-inch display,
refer to your Uconnect Owner’s Manual Supple -
ment.
NOTE:
Uconnect screen images are for illustration
purposes only and may not reflect exact soft -
ware for your vehicle.
CYBERSECURITY
Your vehicle may be a connected vehicle and
may be equipped with both wired and wireless
networks. These networks allow your vehicle to
send and receive information. This information
allows systems and features in your vehicle to
function properly. Your vehicle may be equipped with certain secu
-
rity features to reduce the risk of unauthorized
and unlawful access to vehicle systems and
wireless communications. Vehicle software
technology continues to evolve over time and
FCA US LLC, working with its suppliers, evalu -
ates and takes appropriate steps as needed.
Similar to a computer or other devices, your
vehicle may require software updates to
improve the usability and performance of your
systems or to reduce the potential risk of unau -
thorized and unlawful access to your vehicle
systems.
The risk of unauthorized and unlawful access to
your vehicle systems may still exist, even if the
most recent version of vehicle software (such as
Uconnect software) is installed.
WARNING!
It is not possible to know or to predict all of
the possible outcomes if your vehicle’s
systems are breached. It may be possible
that vehicle systems, including safety
related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury
or death.
ONLY insert media (e.g., USB, SD card, or
CD) into your vehicle if it came from a
trusted source. Media of unknown origin
could possibly contain malicious software,
and if installed in your vehicle, it may
increase the possibility for vehicle systems
to be breached.
As always, if you experience unusual
vehicle behavior, take your vehicle to your
nearest authorized dealer immediately.
