Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°C). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized MOPAR dealer.
Engine Warm-Up
Avoid full throttle operation when the engine is cold.
When starting a cold engine, bring the engine up to
operating speed slowly to allow the oil pressure to
stabilize as the engine warms up.
NOTE:High-speed, no-load running of a cold engine can
result in excessive white smoke and poor engine perfor-
mance. No-load engine speeds should be kept under
1,200 RPM during the warm-up period, especially in cold
ambient temperature conditions. Your vehicle is equipped with a turbo speed limiter, this
feature limits the engine speed to 1,200 RPM when
engine coolant temperatures are below 70°F (21°C). This
feature is designed to protect the turbocharger from
damage and will only operate in PARK or NEUTRAL.
If temperatures are below 32°F (0°C), operate the engine
at moderate speeds for five minutes before full loads are
applied.
NOTE:
If ambient temperatures are low and the coolant
temperature is below 180°F (82°C), the engine idle speed
will slowly increase to 1,000 RPM after two minutes of
idle, if the following conditions are met:
• Foot is off brake pedal and throttle pedal.
• Automatic transmission is in PARK.
• Vehicle speed is 0 mph (0 km/h).
• Applying the throttle will cancel fast idle.

STARTING AND OPERATING 211

•Operating the exhaust brake at idle will greatly im-
prove warm up rate and will help keep the engine
close to operating temperature during extended idle.
Engine Idling
Avoid prolonged idling, long periods of idling may be
harmful to your engine because combustion chamber
temperatures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
varnish to form on piston rings, engine valves, and
injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the oil and causing rapid wear to the
engine.
If the engine is allowed to idle, under some conditions
the idle speed may increase to 900 RPM then return to
normal idle speed. This is normal operation. NOTE:
For EVIC/DID messages related to the vehicle’s
exhaust system, refer to “Electronic Vehicle Information
Center (EVIC)” or “Driver Information Display (DID)”
for further information.Idle-Up Feature — Automatic Transmission Only
The driver-controlled high idle speed feature will help
increase cylinder temperatures and provide additional
cab heat, however, excessive idling may still cause the
exhaust aftertreatment system to not properly regenerate.
Extended periods of idle time should be avoided.
The Idle-Up feature uses the speed control switches to
increase engine idle speed and quickly warm the vehi-
cle’s interior.
1. With the transmission in PARK, the parking brake applied, and the engine running, push the speed
control switch to the ON position, then push the SET
switch.
212 STARTING AND OPERATING

2. The engine RPM will go up to 1100 RPM. To increasethe RPM, push and hold the ACCEL/RESUME switch
and the idle speed will increase to approximately 1500
RPM. To decrease the RPM, push and hold the DECEL
switch and the idle speed will decrease to approxi-
mately 1100 RPM.
3. To cancel the Idle–Up feature, either push the CAN- CEL switch, push the ON/OFF switch, or press the
brake pedal.
Stopping The Engine
Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period will
allow the lubricating oil and coolant to carry excess heat
away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially impor-
tant for turbocharged, charge air-cooled engines. NOTE:
•
During engine shut down on vehicles equipped with
manual transmissions, it is normal for the diesel en-
gine to resonate heavily for a moment during engine
shut off. When the engine is connected to a manual
transmission, this resonance causes load gear rattle
from the transmission. This is commonly referred to as
“shut down rattle.” The manufacturer recommends
performing engine shut down with the clutch pedal
pushed to the floor (clutch disengaged). When engine
shut down is performed in this manner the rattle is
reduced (not eliminated).
• Refer to the following chart for proper engine shut-
down.

STARTING AND OPERATING 213

Operating Precautions
Avoid Overheating The Engine
The temperature of the engine coolant (antifreeze) (a
mixture of 50% ethylene-glycol and 50% water) must not
exceed the normal range of the temperature gauge 240°F
(116°C) with a 21 psi (145 kPa) coolant pressure cap.
Usually the engine coolant (antifreeze) temperature indi-
cated during operation will be to the left of center in the
normal range of the gauge.
Avoid Low Coolant Temperature Operation
Continual operation at low engine coolant (antifreeze)
temperature below the normal range on the gauge 140°F
(60°C) can be harmful to the engine. Low engine coolant
(antifreeze) temperature can cause incomplete combus-
tion which allows carbon and varnish to form on pistonrings and injector nozzles. Also, the unburned fuel can
enter the crankcase, diluting the lubricating oil and
causing rapid wear to the engine.
Cooling System Tips — Automatic Transmission
To reduce potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
•
City Driving —
When stopped, shift the transmission into NEUTRAL
and increase engine idle speed.
• Highway Driving —
Reduce your speed.
• Up Steep Hills —
Select a lower transmission gear.
• Air Conditioning —
Turn it off temporarily.

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealership or qualified
repair center.
(Continued)
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. The best time to check
the oil level is before starting the engine after it has been

5. Place the shift lever momentarily into each gear posi-tion (allowing time for the transmission to fully en-
gage in each position), ending with the transmission in
PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated. 7. Remove the dipstick again and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid
if the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube
to bring it to the proper level. Do not overfill.Use
ONLY the specified fluid (see Fluids, Lubricants, and
Genuine Parts for fluid specifications). After adding
any quantity of oil through the dipstick tube, wait a
minimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.

MAINTENANCE SCHEDULE — DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accuracy
of the oil level reading. Add oil only when the level is at
or below the ADD or MIN mark.
Once A Month
• Inspect the batteries, and clean and tighten the termi-
nals as required. •
Check the fluid levels of the coolant reservoir, brake
master cylinder, and automatic transmission (if
equipped), and add as needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect engine air filter.
• Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends.
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts.
Oil Change Indicator System — Cummins Diesel
