ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the recom -
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”. NOTE:
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not interpreted
as a problem. Please check your oil level with the engine oil
indicator often during the break in period. Add oil as
required.
PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with an Electric Park Brake System
(EPB) that offers simple operation, and some additional
features that make the parking brake more convenient and
useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the vehicle,
make sure that the park brake is applied. Also, be certain to
leave the transmission in PARK.
You can engage the park brake in two ways:
• Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake feature in
the customer programmable features section of the Ucon -
nect settings.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.5

406 STARTING AND OPERATING
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo area
so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle, springs,
tires or wheels). Heavier axles or suspension components
sometimes specified by purchasers for increased durability
does not necessarily increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents the
actual tire size on your vehicle. Replacement tires must be
equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for all
loading conditions up to full Gross Axle Weight Rating
(GAWR).
Curb Weight
The curb weight of a vehicle is defined as the total weight of
the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to insure that the Gross Vehicle Weight Rating (GVWR)
has not been exceeded. The weight on the front and rear of
the vehicle should then be determined separately to be sure
that the load is properly distributed over the front and rear
axle. Weighing the vehicle may show that the Gross Axle
Weight Rating (GAWR) of either the front or rear axles has
been exceeded but the total load is within the specified
GVWR. If so, weight must be shifted from front to rear or
rear to front as appropriate until the specified weight limita-
tions are met. Store the heavier items down low and be sure

Off-Road Driving Tips
Care should be taken when attempting to climb steep hills or
driving diagonally across a hill or slope. If natural obstacles
force you to travel diagonally up or down a hill, choose a
mild angle and keep as little side tilt as possible. Keep the
vehicle moving and make turns slowly and cautiously.
If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL or diago-
nally across the hill. When driving over sand, mud, and other soft terrain, shift to
low gear and drive steadily. Apply the accelerator slowly to
avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
• Completely inspect the underbody of your vehicle. Check
tires, body structure, steering, suspension, and exhaust
system for damage.
• Inspect the radiator for mud and debris and clean as required.
• Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and suspension.
Retighten them, if required, and torque to the values spec -
ified in the Service Manual.
• Check for accumulations of plants or brush. These things could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• Driving through standing water may cause damage to
your vehicle’s drivetrain components. Always inspect
your vehicle’s fluids (i.e., engine oil, transmission, axle,
etc.) for signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through standing
water. Do not continue to operate the vehicle if any
fluid appears contaminated, as this may result in
further damage. Such damage is not covered by the
New Vehicle Limited Warranty.
• Getting water inside your vehicle’s engine can cause it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered by
the New Vehicle Limited Warranty. CAUTION!

Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or rusty
in appearance, the system should be drained, flushed and
refilled with fresh coolant. 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 cooling system hoses for brittle rubber,
cracking, tears, cuts and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.
DO NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT. Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add coolant properly.
Failure to fill these systems properly could lead to severe
internal engine damage. If any coolant is needed to be added
to the system please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section for the proper
maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica
-
tions” for further information.
NOTE:
• 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 Additive Technology (HOAT) engine
coolant (antifreeze) or any “globally compatible” coolant
• When working near the radiator cooling fan, discon
-
nect the fan motor lead or 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.

512 SERVICING AND MAINTENANCE
• If frequent engine coolant (antifreeze) additions arerequired, the cooling system should be pressure tested for
leaks.
• Maintain engine coolant (antifreeze) concentration at a minimum of 50% OAT coolant (conforming to MS.90032)
and distilled water for proper corrosion protection of your
engine which contains aluminum components.
• Make sure that the coolant expansion bottle overflow hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter oper -
ation. If replacement is ever necessary, install ONLY the
correct type thermostat. Other designs may result in unsat -
isfactory engine coolant (antifreeze) performance, poor
gas mileage, and increased emissions.
Brake System
In order to ensure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals. Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately if
the brake system warning lamp indicates system failure.
If necessary, add fluid to bring level within the designated
marks on the side of the reservoir of the brake master
cylinder. Be sure to clean the top of the master cylinder area
before removing cap.
With disc brakes the fluid level can be expected to fall as the
brake linings wear. However, an unexpected drop in fluid
level may be caused by a leak and a system check should be
conducted.
Refer to “Fluids And Lubricants” in “Technical Specifica
-
tions” for further information.
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
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.

Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to ensure
optimum transmission performance and life. Use only the
manufacturer’s specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It is
important to maintain the transmission fluid at the correct
level using the recommended fluid. No chemical flushes
should be used in any transmission; only the approved lubri-
cant should be used.
WARNING!
• Use only manufacturer's recommended brake fluid. Refer to “Fluids And Lubricants” in “Technical Speci -
fications” for further information. Using the wrong
type of brake fluid can severely damage your brake
system and/or impair its performance. The proper type
of brake fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
• To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been in
a tightly closed container. Keep the master cylinder
reservoir cap secured at all times. Brake fluid in a open
container absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil unexpect -
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.
• Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate thebrake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
CAUTION!
Using a transmission fluid other than the manufacturer’s
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.

Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected. If
gear oil leakage is suspected inspect the fluid level. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information. This inspection should be made with
the vehicle in a level position.
The fluid level should be even with the bottom of the fill hole
(within 1/4 in (6.4 mm) of edge of hole) for the front axle and
rear axle.
Lubricant Selection
Refer to “Fluids And Lubricants” in “Technical Specifica-
tion” for further information.
NOTE:
The presence of water in the gear lubricant will result in
corrosion and possible failure of differential components.
Operation of the vehicle in water, as may be encountered in
some off-highway types of service, will require draining and
refilling the axle to avoid damage. Limited-Slip Differentials
Rear axles equipped with a Limited Slip Differential require
that 5 oz. (148 ml) Mopar Limited Slip Additive be added to
the gear lubricant. Refer to “Fluids And Lubricants” in
“Technical Specification” for further information. The
Mopar Limited Slip Additive should be added to the gear
lubricant whenever a fluid change is made to an axle
equipped with a Limited Slip Differential.
NOTE:
When refilling a limited slip differential axle which requires
a friction modification additive, the additive should be
added before the gear lubricant to ensure proper additive
fill.
Drain And Refill
Refer to the “Maintenance Plan” for the proper maintenance
intervals.
Transfer Case
Selection Of Lubricant
Use only the manufacturer's recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.
