GETTING TO KNOW YOUR INSTRUMENT PANEL 183
— Electric Power Steering Fault Warning Light
This warning light will turn on when there's a fault with the
EPS (Electric Power Steering) system. Refer to “Power
Steering” in “Starting And Operating” for further informa -
tion.
— Trailer Brake Disconnected Warning Light
This warning light will illuminate when the Trailer Brake has
been disconnected.
— Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to warn of a high transmis -
sion fluid temperature. This may occur with strenuous usage
such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle or slightly faster, with the trans -
mission in PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to drive normally. — Door Open Warning Light
This indicator will illuminate when a door is ajar/open and
not fully closed.
NOTE:
If the vehicle is moving there will also be a single chime.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure.

500 SERVICING AND MAINTENANCE
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check tire pressure and look for unusual wear or damage.Rotate tires at the first sign of irregular wear, even if it
occurs before the oil indicator system turns on. • Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis -
sion (six-speed only) and fill as needed
• Check function of all interior and exterior lights
Maintenance Plan
Required Maintenance
Refer to the Maintenance Plan 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 irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• 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. If required, replace air cleaner filter.

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 function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, 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.
Hydraulic Brake Assist — 2500/3500 Models Only
(Except Power Wagon)
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.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.

bolts and clean or remove any dirt or oil before tightening.Lug Nut/Bolt

ComponentFluid, Lubricant, or Genuine Part
Automatic Transmission – Eight-Speed Automatic (For
Diesel Engine see Diesel Supplement) Use only Mopar ZF 8&9 Speed ATF Automatic Transmission
Fluid, or equivalent. Failure to use the correct fluid may
affect the function or performance of your transmission.
Transfer Case We recommend you use Mopar Transfer Case Lubricant for
Borg Warner 44-44 and 44-45.
Front and Rear Axle We recommend you use SAE 75W-85 HD Ram GL-5
Synthetic Axle Lubricant in 9.25 Front & 11.5 Rear Axles. Use
Mopar Synthetic Gear Lubricant SAE 75W-140 (MS-8985) in
12.0 Rear axles. Limited slip additive is required for limited
slip axles.
Brake Master Cylinder We recommend you use Mopar DOT 3.
Power Steering Reservoir We recommend you use Mopar Power Steering Fluid +4 or
Mopar ATF+4 Automatic Transmission Fluid.
