system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.
NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes Anti-Lock Brake Sys-
tem (ABS), Traction Control System (TCS), Brake Assist
System (BAS), Electronic Roll Mitigation (ERM), Hill
Start Assist (HSA), Electronic Stability Control (ESC) and
Trailer Sway Control (TSC). All of the systems work
together to enhance vehicle stability and control in vari-
ous driving conditions, and are commonly referred to as
ESC.
Anti-Lock Brake System (ABS)
The ABS aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.
NOTE: ABS improves steering control of the vehicle
during hard braking maneuvers.
WARNING!
• ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded.

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.

Chassis
ComponentFluid, Lubricant, or Genuine Part
Automatic Transmission (5.7L, and 6.4L En-
gine with 66RFE Transmission) (For Diesel
Engine see Diesel Supplement) We recommend you use MOPAR® ATF+4® Automatic Transmis-
sion Fluid or equivalent licensed ATF+4® product. Failure to use
ATF+4® fluid may affect the function or performance of your
transmission.
Automatic Transmission (6.4L Engine with
AS66RC Transmission) We recommend you use MOPAR® ASRC Automatic Transmission
Fluid or equivalent. Failure to use the proper fluid may affect the
function or performance of your transmission.
Transfer Case We recommend you use MOPAR® BW44-44 Transfer Case Fluid.
Front and Rear Axle Fluid (4500/5500) We recommend you use GL-5 SAE 75W-90 Synthetic (MS-9763).
Brake Master Cylinder We recommend you use MOPAR® DOT 3 and SAE J1703. If DOT
3 brake fluid is not available, then DOT 4 is acceptable.
Power Steering Reservoir We recommend you use MOPAR® Power Steering Fluid +4,
MOPAR® ATF+4® Automatic Transmission Fluid.

•Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic trans-
mission as needed
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following
pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter.
At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
•Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required.
• Inspect automatic transmission fluid if equipped
with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses
and park brake.
• Inspect engine cooling system protection and
hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or
off-road conditions.
• Lube the front drive shaft fitting.
