Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
your Scheduled Maintenance guide for more
information.
Trailer towing tips
²Practice turning, stopping and backing up in an
area before starting on a trip to get the feel of the
vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs
and other obstacles.
²Allow more distance for stopping with a trailer
attached.
²The trailer tongue weight should be 10% of the
loaded trailer weight.
²After you have traveled 80 km (50 miles),
thoroughly check your hitch, electrical
connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in
hot weather, place the gearshift in P (Park) and
increase idle speed. This aids engine cooling and
air conditioner efficiency.
²Vehicles with trailers should not be parked on a
grade. If you must park on a grade, place wheel
chocks under the trailer's wheels.
DRIVING THROUGH WATER
Do not drive quickly through standing water,
especially if the depth is unknown. Traction or brake
capability may be limited and if the ignition system
gets wet, your engine may stall. Water may also
enter your engine's air intake and severely damage
your engine.
If driving through deep or standing water is
unavoidable, proceed very slowly. Never drive
through water that is higher than the bottom of the
hubs.

HAZARD FLASHER
Use only in an emergency to warn traffic of vehicle
breakdown, approaching danger, etc. The hazard
flashers can be operated when the ignition is off.
²The hazard lights
control is located on
top of the steering
column.
²
Depress hazard lights
control to activate all
hazard flashers
simultaneously.
²Depress control again to turn the flashers off.
FUEL PUMP SHUT-OFF SWITCH
After a collision, if the engine cranks but does not
start, the fuel pump shut-off switch may have been
activated. The shut-off switch is a device intended to
stop the electric fuel pump when your vehicle has
been involved in a substantial jolt.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump
shut-off switch by pushing in the reset button.
4. Turn the ignition to the ON position. Pause for a
few seconds and return the key to the OFF position.
5. Make a further check for leaks in the fuel system.

EPA window sticker
Every new vehicle should have the EPA window
sticker. Contact your dealer if the window sticker is
not supplied with your vehicle. The EPA window
sticker should be your guide for the fuel economy
comparisons with other vehicles.
It is important to note the box in the lower left
corner of the window sticker. These numbers
represent the Range of Km/L (MPG) expected on
the vehicle, depending upon the driver's method of
operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission
control components and a catalytic converter which
will enable your vehicle to comply with applicable
exhaust emission standards. To make sure that the
catalytic converter and other emission control
components continue to work properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is
moving, especially at high speeds.
²Have the items listed in your Scheduled
Maintenance Guide performed according to the
specified schedule.
The scheduled maintenance items listed in the
Scheduled Maintenance Guide are essential to the
life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized
parts are used for maintenance replacements or for
service of components affecting emission control,
such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and
durability.
