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
Note: The maximum roof load is based on
the load being evenly distributed on the
crossbars.

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.

WARNING: Park your vehicle so that
you do not obstruct the flow of traffic or
place yourself in any danger and set up a
warning triangle. WARNING:
Do not get under a
vehicle that is only supported by a vehicle
jack. WARNING: Do not attempt to change
a tire on the side of the vehicle close to
moving traffic. Pull far enough off the road
to avoid the danger of being hit when
operating the jack or changing the wheel. WARNING:
Use only the specified
jacking points. If you use other positions,
you may damage the body, steering,
suspension, engine, braking system or the
fuel lines. WARNING:
Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer. WARNING:
The jack supplied with
this vehicle is only intended for changing
wheels. Do not use the vehicle jack other
than when you are changing a wheel in an
emergency. WARNING:
Make sure there is no
grease or oil on the threads or the surface
between the wheel lugs and nuts. This can
cause the lug nuts to loosen while driving. Note:
The jack does not require
maintenance or additional lubrication over
the service life of your vehicle.
Note: Passengers should not remain in your
vehicle when the vehicle is being jacked.
1. Park on a level surface, set the parking brake and activate the hazard flashers.
2. Place the transmission in park (P) and turn the engine off.
