CAUTION!
Mixing of engine coolant (antifreeze)
other than specified Organic Additive
Technology (OAT) engine coolant (anti -
freeze), may result in engine damage
and may decrease corrosion protection.
Organic Additive Technology (OAT)
engine coolant is different and should
not be mixed with Hybrid Organic Addi -
tive 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 authorized dealer as soon as possible.Do not use water alone or alcohol-based
engine coolant (antifreeze) 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 (antifreeze). Use of propylene
glycol-based engine coolant (antifreeze)
is not recommended.
The use of products with different spec-
ifications than those indicated above
could cause damage to the engine that is
not covered by the warranty.
CAUTION! (Continued)

Use AdBlue® only according to DIN 70 070
and ISO 22241-1. Other fluids may cause
damage to the system: also exhaust emis -
sions would no longer comply with the law.

The distribution companies are responsible
for the compliance of their product.
Observe the precautions of storage and
servicing, in order to preserve the initial
qualities. The manufacturer of the vehicle
does not recognize any guarantee in case
of malfunctions and damage caused to the
vehicle due to the use of AdBlue® not in
accordance with regulations.

FUEL CONSUMPTION AND
CO
2 EMISSIONS

The fuel consumption and CO2 emission
figures declared by the manufacturer are deter -
mined on the basis of the type-approval tests
laid down by the applicable standards in the
country where the vehicle is registered.

The type of route, traffic conditions, weather
conditions, driving style, general condition of
the vehicle, trim level/equipment/ accesso -
ries, use of the climate control system,
vehicle load, presence of roof racks and other
situations that adversely affect the aerody -
namics or wind resistance lead to different
fuel consumption values than those
measured. The fuel consumption will only become more
regular after driving the first 1,864 miles
(3,000 km).
To find the specific fuel consumption and
CO
2 emission figures for this vehicle, please
refer to the data in the Certificate of Confor -
mity (if equipped), and the related documen -
tation that accompanies the vehicle (if
equipped).

UCONNECT SYSTEMS
For detailed information about your Ucon-
nect system, refer to your Uconnect Owner’s
Manual Supplement.
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 wire -
less 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
security features to reduce the risk of unau -
thorized and unlawful access to vehicle
systems and wireless communications.
Vehicle software technology continues to
evolve over time and FCA, working with its
suppliers, evaluates and takes appropriate
steps as needed. Similar to a computer or
other devices, your vehicle may require soft -
ware updates to improve the usability and performance of your systems or to reduce the
potential risk of unauthorized 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.
NOTE:
FCA or your dealer may contact you
directly regarding software updates.
To help further improve vehicle security
and minimize the potential risk of a secu
-
rity breach, vehicle owners should:
Only connect and use trusted media devices (e.g. personal mobile phones,
USBs, CDs). 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 soft -
ware, 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.
