CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
NOTE:
When using a portable battery booster pack,
follow the manufacturer's operating instruc-
tions and precautions.
Preparations For Jump Start
The battery in your vehicle is located in the
left rear of the engine compartment, behind
the Power Distribution Center.NOTE:
The positive battery post is covered with a
protective cap. Lift up on the cap to gain
access to the post.
WARNING!
• Take care to avoid the radiator cooling
fan whenever the hood is raised. It can
start anytime the ignition switch is ON.
You can be injured by moving fan blades.
WARNING!
• Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
• Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
NOTE:
Never use a fast battery charger to start the
engine, as this could damage the electronic
systems of your vehicle, particularly the igni-
tion and engine fuel supply control units.
1. Apply the parking brake, shift the auto-
matic transmission into PARK and turn
the ignition OFF.
2. Turn off the heater, radio, and all unnec-
essary electrical accessories.
3. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cable’s reach, apply the parking brake and
make sure the ignition is OFF.

WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride ComfortSafety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure.Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump-
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort-
able ride. Over-inflation produces a jarring
and uncomfortable ride.

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.
