Octane Recommendations - Gasoline Engines
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer
fuels posted as Regular with an
octane rating below 87, particularly in
high altitude areas. Do not use fuels with a posted octane rating below 87.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
RUNNING OUT OF FUEL
Gasoline Engine
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time takes a few seconds longer
than normal.
•If your vehicle is equipped with dual fuel tanks,adding
four–five gallons (15–19 liters) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
four–five gallons (15–19 liters) may be required.
•The service engine soon indicator may come on. For more
information on the service engine soon indicator, see theInstrument
Clusterchapter.
SeeGeneral informationin theInformation Displayschapter for
information on Miles to Empty.
Diesel Engine
Avoid running out of fuel as this allows air to enter the fuel system,
which makes restarting the vehicle difficult.
If you have run out of fuel:
•If your vehicle is equipped with dual fuel tanks,adding
four–five gallons (15–19 liters) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
four–five gallons (15–19 liters) may be required.

•The fuel system must be primed before attempting to restart the
engine. See your engine operator’s manual for instructions on priming
the engine.
•Use caution not to overheat and damage the starter by cranking the
engine for an excessive period of time. You may need to crank the
engine for a longer time than normal. If the engine fails to start in
30 seconds, turn the ignition to the off position and wait for
two minutes before cranking the engine again.
•Any remaining trapped air self-purges from the fuel system once the
engine starts running.
•The engine may run rough and produce white smoke while air is in
the fuel system. This is normal and should stop after a short period of
time.
SeeGeneral informationin theInformation Displayschapter for
information on Miles to Empty.
REFUELING
WARNING:Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
•Read and follow all the instructions on the pump island.
•Turn off your engine when you are refueling.
•Do not smoke if you are near fuel or refueling your vehicle.
•Keep sparks, flames and smoking materials away from fuel.
•Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle - this is against the law in some places.
•Keep children away from the fuel pump; never let children pump
fuel.
•Do not use personal electronic devices while refueling.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.

SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM (DIESEL
ENGINE ONLY)
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of Maintaining the DEF Level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled before the DEF
gauge in the instrument cluster reaches the first low level warning
(seeWarning messages and vehicle operations).
The engine control unit monitors the amount of fluid available in the
DEF tank. Failure to maintain an adequate amount of DEF in the system
generates warning messages that appear in the information display and,
unless the DEF tank is refilled, leads to a forced reduction of engine
operations.
Warning Messages and Vehicle Operations
The instrument cluster contains a DEF gauge and indicator lights to alert
you to any low DEF level conditions. The indicator lights illuminate if the
DEF gauge level drops below 0.5 gallons (1.9 liters) in the 5 gallon
(19.0 liters) DEF tank or 1 gallon (3.8 liters) in the 9 gallon (34.0 liters)
DEF tank.
Upon filling the DEF tank after a low level warning, normal operation
resumes when the vehicle is restarted.

MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Manual transmission shift patterns are displayed on either the shift lever
knob or the sun visor. Study this information carefully before you drive
the vehicle even though you may be familiar with similar units. Do not
attempt to drive the vehicle without knowing the exact shift pattern of
the transmission. Consult your authorized dealer if any questions exist as
to the shifting instructions posted in your vehicle.
Driving Hints
WARNING:Do not coast the vehicle with the clutch pedal
pressed or with the transmission in neutral. This practice could
result in loss of vehicle control.
The following driving hints are provided as a brief, general guide in
operating the different manual transmissions used in your vehicle.
•When shifting into first gear or reverse with your vehicle standing
still, quickly release and press the clutch pedal (if necessary to
complete gear engagement).
•Always use the lowest (or most appropriate) gear to start the vehicle.
•Always use a gear ratio low enough to allow the engine to operate
above the minimum engine operation speed range.
•Do not lug the engine.
•Do not slam or jerk the gearshift lever into gear.
•When more power is required, shift to a lower gear and accelerate
the engine near the governed speed.
To go forward, press the clutch pedal in and shift into first gear while
the engine is idling. Engage the clutch while pressing the accelerator to
start forward. Operate the clutch and upshift as required by driving
conditions.
To go backward, put the gearshift lever in reverse and engaging the
clutch while pressing lightly on the accelerator.
Shifting with a Synchronized Transmission
With the clutch pedal pressed in, use the second gear synchronizer to
stop the clutch disc rotation; this allows smooth engagement of first gear
or reverse. To complete the gear engagement, it may be necessary to
apply light pressure to the gearshift lever during initial engagement of
the clutch. It takes a second or two to match gear speeds; steady
pressure on the gearshift lever helps the synchronizer perform its job
more quickly. If the gearshift lever is forced into position, this action
defeats the purpose of the synchronizer by causing gear clash.

Allison 2500
WARNING: To avoid sudden, unexpected vehicle movement
and possible personal injury or death:
1. Bring the vehicle to a complete stop.
2. Shift the transmission into positionN.
3. Apply the parking brake and make sure it is holding properly.
4. Turn the engine off when you leave the vehicle.Never leave the
vehicle unattended when the engine is running.
This transmission is available with a column-mounted gearshift lever. The
gear positions are displayed on the RNDL in the instrument cluster.
Allison 3000
Note:For more information regarding this transmission, see the separate
Allison 3000 Series Operator’s Manual.
The Allison 3000 series offers two shift modes: Performance and
Economy.
Performance mode gives the best all-around transmission operation. The
transmission defaults to this mode when you start the engine. Pressing
MODE on the shifter switches to Economy mode and illuminates the
Mode ON lamp.
Economy mode provides operation at lower engine RPM while
maintaining adequate performance.
If the engine speed is above idle when a gear is selected using the
shifter, the vehicle does not move; the shifter must be moved to re-select
a gear after the engine speed returns to idle.
Torque Lock
If your vehicle is parked on an incline and positionPis not properly
engaged (the parking brake is not applied before the transmission is
shifted into positionP),the weight of the vehicle may generate an
excessive amount of torque on the parking pawl, making it difficult to
shift the transmission out of positionP.Hold the brake pedal down while
shifting out of positionP,then release the parking brake.

Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
What You Should Know About Fail-Safe Cooling (If Equipped)
(Gasoline Engine Only)
WARNING:If fail-safe cooling activates, pull off the road as soon
as safely possible and turn the engine off. The engine may
automatically shut off while driving without further indication.
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The fail-safe distance depends on ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat:
•The engine coolant temperature gauge moves to the red (hot) area.
•The information display indicates the engine is overheating.
•The service engine soon indicator illuminates.
If the engine reaches a preset over-temperature condition, the engine
automatically switches to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When Fail-Safe Mode Is Activated
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
Note:Driving the vehicle without repairing the engine problem increases
the chance of engine damage. Take your vehicle to an authorized dealer
as soon as possible.
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle is not able to maintain high-speed
operation and the engine runs rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage; therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Restart the engine and take your vehicle to an authorized dealer.
