BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still func-
tion with some loss of overall braking effectiveness. This
will be evident by increased pedal travel during applica-
tion, greater pedal force required to slow or stop, and
activation of the “Brake Warning Light” and the “ABS
Warning Light” (if equipped) during brake use.
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
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.
Hydraulic Brake Assist
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
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 (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start442 STARTING AND OPERATING

Chassis
Component Fluid, Lubricant, or Genuine Part
Automatic Transmission (6.4L Engine with 66RFE Trans-
mission) (For Diesel Engine See Diesel Supplement) Use only ATF+4 Automatic Transmission Fluid. Failure
to use ATF+4 fluid may affect the function or perfor-
mance of your transmission. We recommend MOPAR
ATF+4 fluid.
Automatic Transmission (6.4L Engine with AS66RC
Transmission) Use only 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. 7MAINTAINING YOUR VEHICLE 629

Once A Month Or Before A Long Trip:
• Check engine oil level
• 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 and fill 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.
• 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. 8MAINTENANCE SCHEDULES 633
