•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, See
Jump Starting the Vehicle (page 153).
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump.
• Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive •
Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter
If fuses burn out WARNING
Replacement fuses and circuit
breakers must always be the same
rating as the original equipment
shown. Never replace a fuse or circuit
breaker with one of a higher rating. Higher
rated fuses or circuit breakers could allow
circuit overloading in the event of a circuit
malfunction, resulting in severe vehicle
damage or personal injury due to fire. Burned-out or blown fuses usually indicate
an electrical short-circuit, although a fuse
may occasionally burn out from vibration.
Insert a second fuse. If this fuse
immediately burns out and you cannot
locate the cause, return your vehicle to
your dealer for a circuit check. See
Changing a Fuse
(page 170).
Selective catalytic reduction system
speed limit and Idle-only modes
If the vehicle ’s speed is limited or in an
idle-only mode, the selective catalytic
reduction system may be limiting the

Calculating Fuel Economy
Do not measure fuel economy during the
first 900 mi (1,500 km) of driving (this is
your engine ’s break-in period); a more
accurate measurement is obtained after
1,900 mi (3,000 km)
.
Fuel expense, frequency of fill ups or fuel
gauge readings are not accurate ways to
measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the fuel tank, record the amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle ’s fuel economy under current
driving conditions. Keeping records during
summer and winter will show how
temperature impacts fuel economy. In
general, your vehicle will use more fuel in
cold temperatures.
Conditions That Affect Fuel Economy
• Heavily loading your vehicle or towing
a trailer may reduce fuel economy at
any speed.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy. •
Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the accelerator pedal.
• Close the windows for high-speed
driving.
EMISSION CONTROL SYSTEM
- 6.8L WARNINGS
Do not park, idle, or drive your vehicle
in dry grass or other dry ground cover.
The emission system heats up the
engine compartment and exhaust system,
which can start a fire. Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes. Your vehicle is equipped with various
emission control components and a
catalytic converter that will enable your
vehicle to comply with applicable exhaust
emission standards. To make sure that the
catalytic converter and other emission
control components continue to work
properly:
•
Use only the specified fuel listed.
• Avoid running out of fuel.

Forced downshifts
•
Allowed in drive (D) with the tow/haul
feature on or off.
• Press the accelerator to the floor.
• Allows transmission to select an
appropriate gear.
Tow/Haul Mode To activate tow/haul, press the
button on the gearshift lever
once. The TOW HAUL indicator
light illuminates in the instrument cluster.
The tow/haul feature:
• Delays upshifts to reduce the frequency
of transmission shifting.
• Provides engine braking in all forward
gears, which slows your vehicle and
assists you in controlling your vehicle
when descending a grade.
• Depending on driving conditions and
load conditions, may downshift the
transmission, slow your vehicle and
control your vehicle speed when
descending a hill, without pressing the
accelerator pedal. The amount of
downshift braking provided will vary
based upon the amount you press the
brake pedal.
The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the gearshift lever twice. The
TOW HAUL light deactivates. Tow/haul
also deactivates when you power down
your vehicle. WARNING
Do not use the tow/haul feature
when driving in icy or slippery
conditions as the increased engine
braking can cause the rear wheels to slide
and your vehicle to swing around with the
possible loss of vehicle control. Understanding your SelectShift
Automatic
™ transmission
Your vehicle is equipped with a SelectShift
Automatic transmission gearshift lever.
SelectShift Automatic transmission gives
you the ability to change gears up or down
(without a clutch) as desired. Use the buttons on the shifter to lock or
unlock gears and manually select gears.
Press the + button to upshift or the –
button to downshift.
