FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank after running out of fuel. Included in the
advertised capacity is an empty reserve. The
empty reserve is an unspecified amount of
fuel that remains in the fuel tank when the
fuel gauge indicates empty.
Note: The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Fuel Economy
Your vehicle calculates fuel economy figures
through the trip computer average fuel
function. See General Information (page
116). The first 1,000 mi (1,500 km) of driving is the
break-in period of the engine. A more
accurate measurement is obtained after
2,000 mi (3,000 km)
.
Impacting Fuel Economy
• Incorrect tire inflation pressures.
• Fully loading your vehicle.
• Carrying unnecessary weight.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks.
• Using fuel blended with alcohol.
See
Fuel Quality (page 182).
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You may get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal floor.
Failure to follow these instructions may
result in fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components. Similar
federal or provincial laws may apply in
Canada. We do not approve of any vehicle
modification without first determining
applicable laws. Tampering with emissions control
systems including related sensors
or the Diesel Exhaust Fluid system
can result in reduced engine power and the
illumination of the service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by any
person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to the
ultimate purchaser or while it is in use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design. The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
•
Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive exhaust
smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.

•
An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for climactic
conditions.
Note: Some vehicles have a lifetime fuel filter
that is integrated with the fuel tank. Regular
maintenance or replacement is not needed.
Note: If these checks do not help you correct
the concern, have your vehicle checked as
soon as possible.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNING:
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 vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 290).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.

If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may not
have symptoms that are apparent, continued
driving with the service engine soon indicator
on can result in increased emissions, lower
fuel economy, reduced engine and
transmission smoothness and lead to more
costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs to
inspect the emission control equipment on
your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle
registration.
If the service engine soon indicator
is on or the bulb does not work,
your vehicle may need service.
See On-Board Diagnostics. Your vehicle may not pass the I/M test if the
service engine soon indicator is on or not
working properly (bulb is burned out), or if
the OBD-II system has determined that some
of the emission control systems have not
been properly checked. In this case, the
vehicle is not ready for I/M testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the vehicle
is not ready for I/M testing. To determine if
the vehicle is ready for I/M testing, turn the
ignition key to the on position for 15 seconds
without cranking the engine. If the service
engine soon indicator blinks eight times, it
means that the vehicle is not ready for I/M
testing; if the service engine soon indicator
stays on solid, it means that your vehicle is
ready for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing, you
can perform the following driving cycle
consisting of mixed city and highway driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight
hours with the ignition off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle until
the above driving cycle is complete.
If the vehicle is still not ready for I/M testing,
you need to repeat the above driving cycle.

Provides additional engine braking and
extends lower gear operation to enhance
performance for uphill climbs, hilly terrain
or mountainous areas. This increases
engine RPM during engine braking.
• Provides additional lower gear operation
through the automatic transmission shift
strategy.
• Provides gear selection more quickly and
at higher engine speeds.
SelectShift Automatic ™ Transmission
Your SelectShift Automatic transmission
gives you the ability to change gears
manually.
Paddle Shifters
With your vehicle in drive (D), the paddle
shifters provide temporary manual control.
They allow you the ability to shift gears
quickly, without taking your hands off the
steering wheel.
The system determines when temporary
manual control is no longer in use and
returns to automatic control. You can achieve extensive manual control
by pressing the sport (S) button.
•
Pull the right paddle (+) to upshift.
• Pull the left paddle (-) to downshift. The instrument cluster displays your currently
selected gear.
The transmission automatically upshifts if
your engine speed is too high or downshift
if your engine speed is too low.
Note:
You can exit manual control by making
another shift button selection drive (D), for
example, or by briefly holding the (+) paddle. Manual Park Release WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which means
your vehicle can roll freely. To avoid
unwanted vehicle movement, always fully
apply the parking brake prior to doing this
procedure. Use wheels chocks if
appropriate. WARNING:
If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible. WARNING:
Do not drive your vehicle
until you verify that the stoplamps are
working.
Use the manual park release to move your
transmission from the park (P) position in the
event of an electrical malfunction or

If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle back
onto the pavement only after reducing
your speed. Do not turn the steering
wheel too sharply when returning to the
road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors, with
minor damage to your vehicle rather than
attempt a sudden return to the pavement
which could cause the vehicle to slide
sideways out of control or rollover.
Remember, your safety and the safety of
others should be your primary concern. If Your Vehicle Gets Stuck WARNING: Always set the parking
brake fully and make sure you shift the
gearshift lever to first gear. Switch the
ignition off and remove the key whenever
you leave your vehicle. WARNING:
If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the transmission
and tires may occur or the engine may
overheat. If your vehicle gets stuck in mud or snow,
you can rock it out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle has AdvanceTrac
™ with Roll
Stability Control™, it may be beneficial to
disengage the AdvanceTrac with Roll
Stability Control system when attempting to
rock the vehicle.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid "over-driving"
your vehicle, for example, turn the
steering wheel only as rapidly and as far
as required to avoid the emergency.
Excessive steering results in less vehicle
control, not more. Additionally, use
smooth variations of the accelerator and
brake pedal pressure if changes in
vehicle speed are necessary. Avoid

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 350).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
can reduce stopping distances in critical
situations.Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you switch the ignition on. If
the light does not illuminate during
start up, remains on or flashes, the anti-lock
braking system may be disabled. Have the
system checked by an authorized dealer. If
the anti-lock brake system is disabled,
normal braking is still effective.
See
Warning Lamps and Indicators (page
111).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch the
ignition on to confirm the lamp is
functional. If it does not illuminate
when you switch the ignition on,
or begins to flash at any time, have
the system checked by an authorized dealer.
If the brake warning lamp illuminates with
the parking brake released, have the system
checked immediately.
