STARTING A GASOLINE
ENGINE
(IF EQUIPPED)
When you start the engine, the idle speed
increases, this helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer.
Before starting the engine check the
following:
• Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P) or neutral (N).
• Turn the ignition key to the on position.
Note: Do not touch the accelerator pedal.
1. Fully press the brake pedal.
2. Turn the key to the start position to start the engine. Release the key when
the engine starts.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the
first try, wait for a short period and try again.
Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. Fully press the brake pedal.
2. Fully press the accelerator pedal and hold it there.
3. Start the engine. Stopping the Engine When Your
Vehicle is Stationary
1. Shift into park (P) or neutral (N).
2. Turn the key to the off position.
3. Apply the parking brake.
Stopping the Engine When Your
Vehicle is Moving
WARNING:
Switching off the
engine when the vehicle is still moving
will result in a loss of brake and steering
assistance. The steering will not lock, but
higher effort will be required. When the
ignition is switched off, some electrical
circuits, including air bags, warning lamps
and indicators may also be off. If the
ignition was turned off accidentally, you
can shift into neutral (N) and re-start the
engine.
1. Put the transmission into neutral (N) and use the brakes to bring your vehicle
to a safe stop.
2. When your vehicle has stopped, shift into park (P) or neutral (N) and switch
the ignition off.
3. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING:
If you smell exhaust
fumes inside your vehicle, have your
vehicle checked by your authorized
dealer immediately. Do not drive your
vehicle if you smell exhaust fumes.
Carbon monoxide is present in exhaust
fumes. Take precautions to avoid its
dangerous effects.

Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the
following:
•
Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
STARTING A DIESEL ENGINE (IF
EQUIPPED)
Read all starting instructions carefully
before you start your vehicle.
Diesel Engine Fast Start Glow Plug
System
The diesel engine glow system consists of:
• Eight glow plugs (one per cylinder)
• Glow Plug Control Module
• Engine Coolant Temperature sensor
• Barometric pressure sensor
• Environmental temperature sensor
The powertrain and glow plug control
modules electronically control the glow
plug system. After you switch the ignition
on the glow plug control module
immediately energizes the glow plugs. The
glow plug control module using the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor will determine how long the glow
plugs stay energized. The required time for
the glow plugs to be energized decreases
as the coolant temperature, barometric
pressure and environmental temperature
increase. Before starting the engine, check the
following:
•
Make sure all occupants fasten their
seatbelt.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P) or neutral (N).
• Turn the ignition key to the on position.
Note: Do not press the accelerator during
starting.
Cold Weather Starting WARNING: Do not use starting
fluid, for example ether, in the air intake
system. Such fluid could cause
immediate explosive damage to the
engine and possible personal injury. WARNING:
Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
We recommend using the engine block
heater for starting when the ambient
temperature is at or below
-9°F (-23°C)
See Engine Block Heater (page 97).
When operating in cold weather, you can
use Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from
a reputable manufacturer as needed.
Do not crank the engine for more than 10
seconds as starter damage may occur. If
the engine fails to start, turn the key to the
off position and wait 30 seconds before
trying again.

•
Shortly after the engine has shut down,
the electrical system simulates a key
off and even though the ignition is still
on, the electrical system simulates a
normal accessory delay period before
shutting down.
• You must switch the ignition off to
reset the system before restarting your
vehicle.
The engine idle shutdown timer does not
start if:
• The engine is operating in battery
charge protect or power take-off mode.
• The exhaust emission control device is
regenerating.
ENGINE BLOCK HEATER (IF
EQUIPPED) WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock.
Note: The heater is most effective when
outdoor temperatures are below
0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source. We recommend that you do the following
for a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• 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.
