Installing The Rear Wiper
1. Lift the wiper arm off of the glass.
2. Insert the wiper blade pivot pin into the
opening on the end of the wiper arm and
rotate the wiper in to place.
3. Place with wiper on the glass and close
the tail gate.
Cooling System
WARNING!
• You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
WARNING!
• When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.
Coolant Checks
Check the engine and, intercooler (if
equipped) coolant (antifreeze) protection ev-
ery 12 months (before the onset of freezing
weather, where applicable). If the engine
and, intercooler (if equipped) is dirty or rusty
in appearance, the system should be drained,
flushed and refilled with fresh OAT coolant
(conforming to MS.90032) by an authorized
dealer. Check the front of the A/C condenser
(if equipped) or radiator for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the A/C condenser (if
equipped) or the back of the radiator core.
Check the engine and, intercooler (if
equipped) cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness ofthe connection at the coolant recovery bottle
and radiator. Inspect the entire system for
leaks. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYS-
TEM IS HOT.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should
be checked whenever the vehicle is serviced,
or immediately if the brake system warning

FLUIDS AND LUBRICANTS
Engine
Your vehicle is equipped with an engine oil
that has been thoroughly developed and
tested in order to meet the requirements ofthe Scheduled Servicing Plan. Constant use
of the prescribed lubricants guarantees the
fuel consumption and emission specifica-
tions. Lubricant quality is crucial for engine
operation and duration. If lubricants con-
forming to the specific request are not avail-
able, products that meet the indicated speci-fications can be used to top up, in this case
optimal performance of the engine is not
guaranteed.
Component Fluid, Lubricant, or Genuine Part
Engine Coolant We recommend you use PARAFLUUPFormula OAT (Organic Additive Technology) or
equivalent meeting the requirements of FCA Material Standard MS.90032.
Intercooler – If Equipped We recommend you use PARAFLU
UPFormula OAT (Organic Additive Technology) or
equivalent meeting the requirements of FCA Material Standard MS.90032.
Engine Oil — 2.0L Gasoline Engine We recommend you use API SN PLUS Certified SAE 5W-30 Full Synthetic Engine Oil which
meets the requirements of FCA Material Standard MS-13340. If SN PLUS or equivalent oil
is unavailable then use SAE 0W-30 ACEA C2/API SN Full Synthetic Engine Oil which meets
the requirement of FCA Material Standard 9.55535-GS1, such as SELENIA DIGITEK.
CAUTION!
Failure to use the recommended SN PLUS or equivalent oil can cause engine damage not cov-
ered by the vehicle warranty.
Engine Oil — 3.6L Gasoline Engine We recommend you use, API Certified SAE 0W-20 Engine Oil, meeting the requirements
of FCA Material Standard MS-6395. Refer to your engine oil filler cap for correct SAE
grade.

Component Fluid, Lubricant, or Genuine Part
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, API Certified
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 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.
Fuel Selection — 2.0L Gasoline Engine Minimum 97 Research Octane Number (RON) (EN228 Specifications)
Fuel Selection — 3.6L Gasoline Engine Minimum 91 Research Octane Number (RON) (EN228 Specifications)
Fuel Selection — 2.2L Diesel Engine Diesel For Motor Vehicles (Specification EN590)
Additive For Diesel Emissions AdBlue (UREA) AdBlue (Urea-Water Solution) According To DIN 70 070 and ISO 22241-1
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.
CAUTION!
Organic Additive Technology (OAT) en-
gine coolant is different and should not
be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (an-
tifreeze) or any “globally compatible”
CAUTION!
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

CAUTION!
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 an-
tirust products, as they may not be com-
patible 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
CAUTION!
glycol-based engine coolant (antifreeze)
is not recommended.
• The use of products with different speci-
fications than those indicated above
could cause damage to the engine that
is not covered by the warranty.
• 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 com-
ply with the law.
CAUTION!
• The distribution companies are respon-
sible for the compliance of their prod-
uct. Observe the precautions of storage
and servicing, in order to preserve the
initial qualities. The manufacturer of the
vehicle does not recognize any guaran-
tee in case of malfunctions and damage
caused to the vehicle due to the use of
UREA (AdBlue) not in accordance with
regulations.
Chassis
Component Fluid, Lubricant, or Genuine Part
Automatic Transmission – If Equipped We recommended you use TUTELA TRANSMISSION AS8 Fluid, or equivalent, meeting
requirement of FCA Material Standard 9.55550-AV5 or MS.90030-A5. Failure to use the
correct fluid may affect the function or performance of your transmission.
Transfer Case We recommend you use TUTELA TRANSMISSION FORCE 4 Fluid, or equivalent, meeting
requirement of FCA Material Standard 9.55550-AV4 or MS.9602.
