Engine Oil
It illuminates when you switch
the ignition on.
If it illuminates when the engine
is running this indicates a malfunction.
Stop your vehicle as soon as it is safe to
do so and switch the engine off. Check the
engine oil level. If the oil level is sufficient,
this indicates a system malfunction. Have
your vehicle checked immediately.
See Engine Oil Check (page 249).
Fasten Seatbelt Warning Lamp It illuminates and a chime
sounds until you fasten the
seatbelts.
Front Airbag If it fails to illuminate when you
start your vehicle, continues to
flash or remains on, it indicates
a malfunction. Have the system checked
by your authorized dealer.
Front Fog Lamps
(If Equipped) Lights when you switch the front
fog lamps on.
Head Up Display
(If Equipped) A red beam of lights will
illuminate on the windshield in
certain instances when using
adaptive cruise control and/or the collision
warning system. It will also illuminate
momentarily when you start your vehicle
to make sure the display works. High Beam It will illuminate when you switch
the high beam headlamps on. It
will flash when you use the
headlamp flasher.
Liftgate Ajar Illuminates when you do not
completely close the liftgate.
Low Fuel Level It will illuminate when the fuel
level is low or the fuel tank is
nearly empty. Refuel as soon as
possible.
Low Tire Pressure Warning It illuminates if the tire pressure
in one or more tires is below the
correct tire pressure.

flash at any time, have the system checked
by your authorized dealer.

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray
and fire. 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. Fuels can cause serious injury or
death if misused or mishandled.
Fuel may contain benzene, which is
a cancer-causing agent.
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. Follow these guidelines when refueling:
•
Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Always switch the engine off before
refueling.
• Automotive fuels can be harmful or
fatal if swallowed. Fuel is highly toxic
and if swallowed can cause death or
permanent injury. If fuel is swallowed
immediately call a physician, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
apparent for hours. •
Avoid inhaling fuel vapors. Inhaling fuel
vapor can lead to eye and respiratory
tract irritation. In severe cases,
excessive or prolonged breathing of
fuel vapor can cause serious illness and
permanent injury.
• Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses (if worn), flush
with water for 15 minutes and seek
medical attention. Failure to seek
proper medical attention could lead to
permanent injury.
• Fuels can be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
thoroughly wash your skin with soap
and water. Repeated or prolonged skin
contact causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing fuel vapors could cause an
adverse reaction, serious personal
injury or sickness. Immediately call a
physician if you experience any adverse
reactions.
FUEL QUALITY
Choosing the Right Fuel Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.

engine off and never allow sparks or
open flames near the fuel tank filler
valve. Never smoke or use a cell phone

WARNINGS
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. Do not remove the fuel pump nozzle
from its fully inserted position when
refueling.
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. Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray
and fire. Wait at least five seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into
the fuel tank. 1. Fully open the fuel filler door.
2.
Select the correct fuel pump nozzle for
your vehicle. 3. Insert the fuel pump nozzle up to the
first notch on the nozzle A. Keep the
fuel pump nozzle resting on the fuel
tank filler pipe. 4. Hold the fuel pump nozzle in position
B when refueling. Holding the fuel
pump nozzle in position A can affect
the flow of fuel and shut off the fuel
pump nozzle before the fuel tank is full.

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 153).
• 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.
159
Flex (TP3) , enUSA, Edition date: 201801, Second Printing Fuel and Refueling

•
Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
• Close the windows for high-speed
driving.
DRIVING THROUGH WATER WARNING
Do not drive through flowing or deep
water as you may lose control of your
vehicle.
Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so: •
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
FLOOR MATS WARNINGS
Use a floor mat designed to fit the
footwell of your vehicle that does not
obstruct the pedal area. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury. Secure the floor mat to both
retention devices so that it cannot
slip out of position and interfere with
the pedals. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. Do not place additional floor mats
or any other covering on top of the
original floor mats. This could result
in the floor mat interfering with the
operation of the pedals. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. Always make sure that objects
cannot fall into the driver foot well
while your vehicle is moving. Objects
that are loose can become trapped under
the pedals causing a loss of vehicle control. 219
