increases helping to warm up the engine.
If the engine idle speed does not slow
down, have your vehicle checked as soon
as possible.
Before starting the engine check the
following:
• Make sure all occupants fasten their
seatbelts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.

Guarding Against Exhaust Fumes
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.
Important Ventilating Information
If you stop your vehicle and leave the
engine idling for long periods of time, we
recommend you either open the windows
at least 1 in (3 cm) or set the climate
control to outside air.
STARTING THE ENGINE
STARTING A DIESEL ENGINE

seconds when very cold.
Glow Plug Indicator
If it illuminates, wait until the
glow plug indicator turns off
before starting the engine.
SWITCHING OFF THE ENGINE
Allow the engine to idle for three to five
minutes before shutting it down. The larger
the engine, the greater the need is for this
idling period.
Note:Try to limit engine idle to 10 minutes.
Excessive idling reduces fuel economy.
ENGINE IDLE SHUTDOWN (IF
EQUIPPED)
WARNING: In the event of engine
shutdown, make sure your vehicle is
safely off the road and the problem is
resolved before returning to the road.
Failure to do so may result in a crash,
serious injury or death.
This feature automatically shuts down the
engine when it has been idling in park (P)
or neutral (N) for an extended period,
depending on the setting.
102
Starting and Stopping the Engine

• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

Starting and Stopping the Engine

RUNNING OUT OF FUEL -
DIESEL
Avoid running out of fuel. This allows air to
enter the fuel system and may make it
difficult to restart your vehicle.
If your vehicle runs out of fuel:
• Normally adding 4–5 gal (15–19 L) of
fuel is enough to restart the engine. If
your vehicle is out of fuel and on a
steep grade, more than 5 gal (19 L)
may be required.
• You must purge trapped air from the
system before restarting the engine.
Purging Air From the System
Switch the ignition on for 30 seconds and
then switch the ignition off. Repeat this
operation six times in a row to purge any
trapped air from the fuel system.
Any remaining air in the system self-purges
when the engine starts. The engine may
run rough or produce white smoke when
air remains in the fuel system. This is
normal and stops after a short period. If
the engine continues to run rough, have
your vehicle checked as soon as possible.
Starting the Engine
Do not crank the engine for more than 10
seconds as starter damage may occur. If
the engine fails to start, switch the ignition
off and wait 30 seconds before cranking
the engine again. See Starting a Diesel
Engine (page 102).
RUNNING OUT OF FUEL -
GASOLINE
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.If you run out of fuel:
• You may need to switch 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. When restarting, cranking time
takes a few seconds longer than
normal. With keyless ignition, just start
the engine. Crank time will be longer
than usual.
• Normally, adding 1 gal (3.8 L) of fuel is
enough to restart the engine. If the
vehicle is out of fuel and on a steep
grade, more than 1 gal (3.8 L) may be
required.
• The service engine soon indicator may
come on. See Warning Lamps and
Indicators (page 66).
REFUELING - DIESEL
WARNING: Fuel vapor burns
violently and a fuel fire can cause severe
injuries.
WARNING: Read and follow all the
instructions on the pump island.
WARNING: When refueling always
shut the engine off and never allow
sparks or open flames near the fuel tank
filler valve. Never smoke or use a cell
phone while refueling. Fuel vapor is
extremely hazardous under certain
conditions. Avoid inhaling excess fumes.
WARNING: Stay outside your
vehicle and do not leave the fuel pump
unattended when refueling your vehicle.
WARNING: Keep children away
from the fuel pump. Never let children
pump fuel.

Fuel and Refueling

1. When your vehicle has stopped, shift
into neutral (N) or park (P).
2. Apply the parking brake and switch the
ignition off.
3. Turn the fuel filler cap
counterclockwise and remove it.
4. Refuel your vehicle as required.
5. Replace the fuel filler cap, turn it
clockwise until you feel a strong
resistance.
If the fuel cap warning lamp or a warning
message appears in the instrument cluster,
you may not have installed the fuel filler
cap correctly.
If the fuel cap warning lamp remains on,
at the next opportunity, safely pull off of
the road, remove the fuel filler cap, align
the cap properly and reinstall it. The check
fuel cap warning lamp or warning message
may not reset immediately. It may take
several driving cycles for the indicators to
turn off. A driving cycle consists of an
engine start-up (after four or more hours
with the engine off) followed by normal
city and highway driving.
FUEL CONSUMPTION
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.
Filling the Fuel Tank
For consistent results when refueling:
• Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1,000 mi (1,600 km) of driving (this is
your engine’s break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km) to 3,000 mi
(4,800 km). Also, 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.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per
gallon) fuel consumption, divide miles
traveled by gallons used.

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.
