FUEL REQUIREMENTS —
GASOLINE ENGINES
2.0L Engine
This engine is designed to meet all emission
regulations, and provide satisfactory fuel
economy and performance when using
high-quality unleaded gasoline with a recom-
mended RON of 95.
While operating on gasoline with the
required octane number, hearing a light
knocking sound from the engine is not a
cause for concern. However, if the engine is
heard making a heavy knocking sound, see
your dealer immediately. Use of gasoline
with a lower than recommended octane
number can cause engine failure and may
void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita -
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
2.4L And 3.2L Engines
These engine are designed to meet all emis -
sions regulations and provide excellent fuel
economy and performance when using high
quality unleaded gasoline with a minimum
research octane rating (RON) of 91.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita -
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish
removal may contain active solvents or
similar ingredients. These can harm fuel
system gasket and diaphragm materials.
Fuel Icon Identification Compliant To
EN16942
The following symbols make it easier to
recognize the correct type of fuel to be used
on your vehicle. Before proceeding with the
supply, check the symbols placed inside the
fuel filler flap (if present) and compare them
with the symbol on the fuel pump (if
present).

Engine Oil – (3.2L Gasoline Engine)We recommend you use SELENIA K POWER 5W-20, or equivalent,
meeting the requirements of FCA Material Standard MS-6395. Refer
to your engine oil filler cap for correct SAE grade.
Engine Oil – 2.2L Diesel Engine For best performance and maximum protection under all types of
operating conditions, the manufacturer recommends SELENIA WR
FORWARD engine oils, or equivalent, SAE 0W-30 that meet the
requirements of FCA Material Standard 9.55535-DS1, MS.90047,
and ACEA C2.
NOTE:
If lubricants compliant with the required specifications are not
available, products that comply with the minimum required char-
acteristics can be used for topping off; in this case optimal perfor -
mance of the engine is not guaranteed.
The use of products with specifications other than those indicated
above could cause damage to the engine not covered by the
warranty.
Engine Oil Filter We recommend you use a Mopar Engine Oil Filter.
Spark Plugs – Gas Engines We recommend you use Mopar Spark Plugs.

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 emissions would no longer
comply with the law.
The distribution companies are respon -
sible 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 regula-
tions.
CAUTION! (Continued)
