FUEL REQUIREMENTS —
GASOLINE ENGINE
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 97.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 War-
ranty.
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.
3.6L Engine
These engines 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 Number (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.

MS.90047, and ACEA C2.
NOTE:
• If lubricants compliant with the required specifications are not available, products that
comply with the minimum required characteristics can be used for topping off; in this
case optimal performance 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 Mopar Engine Oil Filter or equivalent.
Spark Plugs We recommend you use Mopar Spark Plugs.

Component Fluid, Lubricant, or Genuine Part
Brake Master Cylinder We recommend you use DOT 3, SAE J1703 brake fluid. If DOT 3 brake fluid is not available
then TUTELA TOP4/S, FMVSS no. 116 DOT 4, ISO 4925 SAE J1704, or equivalent, is
acceptable.
If using DOT 4 brake fluid, the fluid must be changed every 24 months regardless of mileage.
Power Steering Reservoir We recommend you use TUTELA TRANSMISSION FORCE 4 fluid, or equivalent, meeting
requirement of FCA Material Standard 9.55550-AV4 or MS.9602.
FUEL CONSUMPTION AND
CO
2EMISSIONS
The fuel consumption and CO2emission
figures declared by the manufacturer are de-
termined 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, ve-
hicle load, presence of roof racks and othersituations that adversely affect the aerody-
namics or wind resistance lead to different
fuel consumption values than those mea-
sured.
The fuel consumption will only become more
regular after driving the first 1,864 miles
(3000 km).
To find the specific fuel consumption and
CO
2emission figures for this vehicle, please
refer to the data in the Certificate of Confor-
mity, and the related documentation that
accompanies the vehicle.
