STARTING A GASOLINE
ENGINE
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. Note:
You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each
time, without the engine starting, you
reached the 60-second time limit. A
message appears in the information display
alerting you that you exceeded the cranking
time. You cannot attempt to start the
engine for at least 15 minutes. After 15
minutes, you are limited to a 15-second
engine cranking time. You need to wait 60
minutes before you can crank the engine for
60 seconds again.
Before starting your vehicle, check the
following:
• Make sure all occupants have fastened
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).
• Switch the ignition on. For vehicles with
a keyless ignition, see the following
instructions.

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS - 3.3L,
HYBRID ELECTRIC VEHICLE (HEV)
Answer
Question
The high voltage battery is electrically isol-ated from the rest of the vehicle when the
key is off. When you switch the key on, high voltage contactors inside the battery are
closed to make the electricity available to the motor and generator and enable the
vehicle to drive. The clicks are the sound of these contactors as they close and open during start up and shut down.
What are the series of clicks from the cargo
area when I first turn the key in the ignition?
The vehicle's computer will determine if an
engine start is required at key-on. Silent keystart will start the engine if it is necessaryfor cabin heating, windshield defrost, or if the outside temperature is low.
Why does the engine sometimes start at
key-on?
There are several reasons the engine stayson for an extended amount of time when
you first start it. One common reason is to
make sure that the emissions components are warm enough to minimize tailpipe
emissions. As the climate gets cooler, this engine-on time is extended.
Why does it take a long time before the
engine shuts down?
In order to make sure that the climate
control system can begin heating the cabin or defrosting the windshield as soon as a driver requests it, the engine coolant
temperature has to be kept sufficiently hot. Keeping the engine on is required to main- tain the correct coolant temperature.
Why does my engine stay on when it is
extremely cold outside?

If your vehicle runs out of fuel:
•
Add a minimum of 1.3 gal (5 L) of fuel
to restart the engine.
• 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.
Note: If your vehicle is on a steep slope,
more fuel may be required.
Filling a Portable Fuel Container WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container.
Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an
ungrounded fuel container:
• Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
• Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).
• Keep the fuel pump nozzle in contact
with the fuel container when filling it.
• Do not use a device that holds the fuel
pump nozzle lever in the fill position. Adding Fuel From a Portable Fuel
Container WARNING: Do not insert the nozzle
of a fuel container or an aftermarket
funnel into the fuel filler neck. This may
damage the fuel system filler neck or its
seal and cause fuel to run onto the
ground. WARNING:
Do not try to pry open
or push open the capless fuel system
with foreign objects. This could damage
the fuel system and its seal and cause
injury to you or others. WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See Fuel Filler
Funnel Location
(page 188).
Note: Do not use aftermarket funnels as
they may not work with the capless fuel
system and can damage it.
When refueling the vehicle fuel tank from
a fuel container, do the following:
1. Fully open the fuel filler door.
2. Fully insert the fuel filler funnel into the
fuel filler inlet.
189
Explorer (CTW) Canada/United States of America, enUSA, Edition date: 201902, Third-Printing- Fuel and Refueling

3. Apply the parking brake.
4. Fully open the fuel filler door.
5. Check the fuel tank filler valve for any
debris that may be restricting its
movement.
6. Remove any debris from the fuel tank filler valve.
7. Fully insert a fuel pump nozzle or the fuel filler funnel provided with your
vehicle into the fuel filler pipe. See
Fuel Filler Funnel Location (page
188). This action should dislodge any
debris that may be preventing the fuel
tank filler valve from fully closing.
8. Remove the fuel pump nozzle or fuel filler funnel from the fuel filler pipe.
9. Fully close the fuel filler door.
Note: The message may not immediately
reset. If the message continues to appear
and a warning lamp illuminates, have your

REFUELING - HYBRID
ELECTRIC VEHICLE (HEV) WARNING:
Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
Do not pry open the
fuel tank filler valve. This could damage
the fuel system. Failure to follow this
instruction could result in fire, personal
injury or death. WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling. 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:
Stop refueling when
the fuel pump nozzle automatically
shuts off for the first time. Failure to
follow this will fill the expansion space
in the fuel tank and could lead to fuel
overflowing. WARNING:
Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank. WARNING:
The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury. WARNING: Read and follow all the
instructions on the pump island.
1. When you stop your vehicle, shift into park (P) and switch the ignition off. 193
