•
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
Note: Driving through deep water above
the recommended levels can cause vehicle
damage.
If driving through deep or standing water
is unavoidable, proceed very slowly. Never
drive through water that is higher than the
bottom of the wheel rims (for cars) or the
bottom of the hubs (for trucks). When driving through water, traction or
brake capability may be limited. Also,
water may enter your engine
’s air intake
and severely damage your engine or your
vehicle may stall.
Once through the water, always dry the
brakes by moving your vehicle slowly while
applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as
quickly as dry brakes. FLOOR MATS
WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle, leaving the pedal area
unobstructed, and which can be firmly
secured to retention posts so that they
cannot slip out of position and interfere
with the pedals or impair safe operation of
your vehicle in other ways. Incorrectly fitted floor mats can
cause the accelerator pedal to
become stuck in the open position.
This can cause loss of vehicle control. Always correctly install the floor
mats to the retention posts so that
they cannot slip out of position or
obstruct pedal operation. Do not place unsecured floor mats
or any other covering in the foot well.
Do not place additional floor mats
or any other covering on top of the
original floor mats. This will reduce
the pedal clearance and interfere with the
pedal operation. Do not allow objects to fall or
become trapped under the pedals of
your vehicle. This can cause loss of
vehicle control. Carry out regular inspections to make
sure the floor mats are secure.

FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses.
To reduce risk of electrical shock,
always replace the cover to the
power distribution box before
reconnecting the battery or refilling fluid
reservoirs. The power distribution box is located in
the engine compartment. It has
high-current fuses that protect your
vehicle's main electrical systems from
overloads.
If you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery
(page 235).

•
Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE EXHAUST WARNINGS
Failure to maintain the functional
holes, in the tailpipe section of the
exhaust, clean and free of debris or
foreign material may result in the holes
becoming blocked or plugged. Do not
modify or remove the tail-pipe section.
Blocked or plugged holes or
removal/modification of the system could
result in elevated exhaust gas
temperatures which may result in
vehicle/property damage or personal
injury. 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 diesel oxidation
catalytic converter and/or the diesel
particulate filter (DPF). The diesel
oxidation catalytic converter and/or the
DPF heats up to a high temperature after
only a short period of engine operation and
can stay hot even after the engine is turned
off. Failure to follow these instructions may
result in personal injury. The visible holes in the exhaust tip and the
holes under the shield just inboard of the
right rear tire(s) are functional. The holes
need to be kept clear of mud/debris or
foreign material to maintain proper
function of the exhaust system. Clean and
remove debris or foreign material if present
as needed. Spraying with a hose during
regular washing of vehicle should help
keep holes clean and clear of debris or
foreign material.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
•
Clean the windshield with a
non-abrasive glass cleaner.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
fluid.

Note:
Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.
CLEANING THE INTERIOR WARNINGS
Do not use cleaning solvents, bleach
or dye on the vehicle
’s safety belts,
as these actions may weaken the
belt webbing. On vehicles equipped with
seat-mounted airbags, do not use
chemical solvents or strong
detergents. Such products could
contaminate the side airbag system and
affect performance of the side airbag in a
collision. For fabric, carpets, cloth seats, safety belts
and seats equipped with side airbags:
•
Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner.
• If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.
• Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials. CLEANING THE INSTRUMENT
PANEL AND INSTRUMENT
CLUSTER LENS WARNING
Do not use chemical solvents or
strong detergents when cleaning the
steering wheel or instrument panel
to avoid contamination of the airbag
system. Clean the instrument panel and cluster
lens with a clean, damp, white cotton
cloth, then use a clean and dry white
cotton cloth to dry these areas.
•
Avoid cleaners or polishes that increase
the gloss of the upper portion of the
instrument panel. The dull finish in this
area helps protect you from
undesirable windshield reflection.
• Be certain to wash or wipe your hands
clean if you have been in contact with
certain products such as insect
repellent and suntan lotion in order to
avoid possible damage to the interior
painted surfaces.
• Do not use household or glass cleaners
as these may damage the finish of the
instrument panel, interior trim and
cluster lens.
• Do not allow air fresheners and hand
sanitizers to spill onto interior surfaces.
If a spill occurs, wipe off immediately.
Damage may not be covered by your
warranty.
If a staining liquid like coffee or juice has
been spilled on the instrument panel or on
interior trim surfaces, clean as follows:
1. Wipe up spilled liquid using a clean, white, cotton cloth.
