LOAD CARRYING PRECAUTIONS
Keep your loaded vehicle weight within
its design rating capability, with or
without a trailer. Properly loading your
vehicle provides maximum return of
vehicle design performance. Before you
load your vehicle, become familiar with
the following terms for determining your
vehicle
’s weight rating, with or without
a trailer, from the vehicle ’s Tire and
Loading Information label or Safety
Compliance Certification label. WARNING: The appropriate
loading capacity of your vehicle can
be limited either by volume capacity
(how much space is available) or by
payload capacity (how much weight
the vehicle should carry). Once you
have reached the maximum payload
of your vehicle, do not add more
cargo, even if there is space available.
Overloading or improperly loading
your vehicle can contribute to loss of
vehicle control and vehicle rollover. WARNING: Exceeding the Safety
Compliance Certification label vehicle
weight limits can adversely affect the
performance and handling of your
vehicle, cause vehicle damage and
can result in the loss of control of your
vehicle, serious personal injury or
death. WARNING:
Do not use
replacement tires with lower load
carrying capacities than the original
tires because they may lower your
vehicle's GVWR and GAWR limitations.
Replacement tires with a higher limit
than the original tires do not increase
the GVWR and GAWR limitations. WARNING:
Do not exceed the
GVWR or the GAWR specified on the
certification label. WARNING:
Exceeding any
vehicle weight rating can adversely
affect the performance and handling
of your vehicle, cause vehicle damage
and can result in the loss of control of
your vehicle, serious personal injury
or death. WARNING:
When loading the
roof racks, we recommend you evenly
distribute the load, as well as maintain
a low center of gravity. Loaded
vehicles, with higher centers of gravity,
may handle differently than unloaded
vehicles. Take extra precautions, such
as slower speeds and increased
stopping distance, when driving a
heavily loaded vehicle.
The gross combined weight must never
exceed the Gross Combined Weight
Rating.

ROOF RACK (If Equipped)
Roof Rack Precautions
WARNING: Read and follow the
manufacturer's instructions when you are
fitting a roof rack. WARNING:
When loading the roof
racks, we recommend you evenly distribute
the load, as well as maintain a low center
of gravity. Loaded vehicles, with higher
centers of gravity, may handle differently
than unloaded vehicles. Take extra
precautions, such as slower speeds and
increased stopping distance, when driving
a heavily loaded vehicle.
Note: If you use a roof rack, the fuel
consumption of your vehicle will be higher
and you may experience different driving
characteristics. You must place loads directly on the
crossbars fitted to the roof rack side rails.
When using the roof rack system, we
recommend that you use genuine Ford Motor
Company accessory crossbars specifically
designed for your vehicle.
Make sure that you securely fasten the load.
Check the tightness of the load before
driving and at each fuel stop.
Roof Rack Load Capacities
Do not install crossbars if your vehicle has a
moonroof. Do not place any load on your
vehicle if it has a moonroof. Using crossbars
or loading the vehicle roof may void your
vehicle's warranty.
Maximum Recommended Load
Description
0 lb (0 kg)
Vehicles with a moonroof
100 lb (45 kg)
Vehicles without a moonroof

CHECKING THE COOLANT
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information. See Scheduled Maintenance
(page 459).
Note: Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between
-29°F (-34°C) and -35°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration. Adding Coolant WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury. WARNING:
Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal injury. WARNING:
Do not add coolant
further than the MAX mark. WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. Note:
Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Note: Automotive fluids are not
interchangeable.
It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system.
See Capacities
and Specifications (page 407). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and could void
the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 407).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.

CHANGING THE ENGINE AIR
FILTER
WARNING: To reduce the risk of
vehicle damage and personal burn injuries,
do not start your engine with the air
cleaner removed and do not remove it
while the engine is running.
When changing the air filter element, use
only the air filter element listed.
See
Capacities and Specifications (page 400).
For turbocharged equipped vehicles: When
servicing the air cleaner, it is important that
no foreign material enter the air induction
system. The engine and turbocharger are
susceptible to damage from even small
particles.
Change the air filter element at the proper
interval. See Scheduled Maintenance (page
459
). Note:
Failure to use the correct air filter
element may result in severe engine
damage. The customer warranty may be
void for any damage to the engine if the
correct air filter element is not used. 1. Release the clamps that secure the air
filter housing cover.
2. Carefully lift the air filter housing cover.
3. Remove the air filter element from the air
filter housing.
4. Wipe any dirt or debris from the air filter housing and cover to make sure no dirt
gets in the engine and to make sure you
have a good seal. 5.
Install a new air filter element. Be careful
not to crimp the filter element edges
between the air filter housing and cover.
This could cause filter damage and allow
unfiltered air to enter the engine if not
properly seated.
6. Install the air filter housing cover.
7. Engage the clamps to secure the air filter
housing cover to the air filter housing.
CHANGING THE FUEL FILTER
Your vehicle has a lifetime fuel filter that
integrates with the fuel tank. It does not need
regular maintenance or replacement.
