If this telltale turns on, safely pull over and stop the
vehicle. Then, shift the transmission into NEUTRAL and
run the engine at idle or faster until the light turns off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.•Air Suspension Payload Protection Telltale — If
Equipped
This telltale will turn on to indicate that the
maximum payload may have been exceeded or
load leveling cannot be achieved at its current
ride height.
Protection Mode will automatically be selected in
order to “protect” the air suspension system, air
suspension adjustment is limited due to payload.
•Service Stop/Start System Telltale — If Equipped
This telltale will turn on to indicate that the
Stop/Start is Unavailable, service Stop/Start
system.
•Loose Fuel Filler Cap
This telltale will turn on to indicate that the fuel
filler cap may be loose.

Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
Winter Front Usage
A winter front or cold weather cover is to be used in
ambient temperatures below 32°F (0°C), especially dur-
ing extended idle conditions to reduce condensation
build-up within engine crankcase. If a winter front or
cold weather cover is to be used, a percentage of the total
grille opening area must be left uncovered to provide
sufficient air flow to the charge air cooler and automatic
transmission oil cooler. The percentage of opening must
be increased with the increasing ambient air temperature
and/or engine load. If the cooling fan can be heard
cycling frequently, increase the size of the opening in the
winter front. A suitable cold weather cover is available
from your MOPAR® dealer.
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.
216 STARTING AND OPERATING

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.•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.

STARTING AND OPERATING 217

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.

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.
Do Not Operate The Engine With Low Oil Pressure
When the engine is at normal operating temperature, the
minimum oil pressures required are:
Idle 700 to 800 RPM 10 psi (69 kPa)
Full speed and load 30 psi (207 kPa)
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
Do Not Operate The Engine With Failed Parts
All engine failures give some warning before the parts
fail. Be on the alert for changes in performance, sounds,
and visual evidence that the engine requires service.
Some important clues are:
•engine misfiring or vibrating severely
