Automatic arming
The vehicle is armed immediately
after switching the ignition to the 1
(OFF/LOCK) position.
Automatic disarming
Switching the ignition to the 3 (ON) position with acoded keydisarms
the vehicle.
Key information
Your vehicle is supplied withtwo coded keys.Only acoded keywill
start your vehicle. Spare coded keys can be purchased from your
authorized dealer. Your authorized dealer can program your key or you
can “do it yourself.” Refer to theProgramming spare keyssection in
this chapter.
The following items may prevent the vehicle from starting:
•Large metallic objects
•Electronic devices on the key chain that can be used to purchase
gasoline or similar items
•A second key on the same key ring as thecoded key
If any of these items are present, you need to keep these objects from
touching thecoded keywhile starting the engine. These objects and
devices cannot damage thecoded key,but can cause a momentary “no
start” condition if they are too close to the key during engine start. If a
problem occurs, turn ignition the OFF position and restart the engine
with all other objects on the key ring held away from the ignition key.
Check to make sure thecoded keyis an approved Fordcoded key.
If your keys are lost or stolen you will need to do the following:
•Use your spare key to start the vehicle, or
•Have your vehicle towed to a authorized dealer or a locksmith. The
key codes will need to be erased from your vehicle and new key codes
will need to be re-coded.

Understanding the gearshift positions of the 4–speed automatic
transmissionin theDriving chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
If your vehicle is equipped with AdvanceTrac
with RSC, you may
experience AdvanceTrac
with RSC activations during typical cornering
maneuvers with a heavily loaded trailer; this is normal. Cornering at a
slower speed while towing will reduce the tendency of the AdvanceTrac

stability enhancement system to activate.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourScheduled Maintenance
Informationfor more information.
Trailer towing tips
•Practice turning, stopping and backing up 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.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.

If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important safety precautions
A computer system controls the engine’s idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs higher than normal in
order to warm the engine. If the engine idle speed does not slow down
automatically, have the vehicle checked. Do not allow the vehicle to idle
for more than 10 minutes at the higher engine RPM.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and Safety Restraintschapter.
2. Make sure the headlamps and vehicle accessories are off.
3. Make sure the gearshift is in P
(Park).
4. Make sure the parking brake is
set.
5. Turn the key to 3 (ON) without
turning the key to 4 (START).

Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Anti-lock brake system (ABS)
On ABS-equipped vehicles, a noise from the hydraulic pump motor and
pulsation in the pedal may be observed during ABS braking events. Pedal
pulsation coupled with noise while braking under panic conditions or on
loose gravel, bumps, wet or snowy roads is normal and indicates proper
functioning of the vehicle’s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized dealer.
The ABS operates by detecting the onset of wheel lockup during brake
applications and compensates for this tendency. The wheels are
prevented from locking even when the brakes are firmly applied.
Using ABS
•In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
•The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.

Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
with RSC performs a system self-check. During
AdvanceTrac
with RSC system operation you may experience the
following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTrac
with RSC indicator light will flash
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTrac
with RSC
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
with Roll Stability Controlsystem. Also, do
not install a stereo loudspeaker near the front center console or
under either front seat. The speaker vibrations can adversely
affect the AdvanceTrac
with Roll Stability Controlsensors
located in this area.
Note:Pressing the AdvanceTrac
with RSC button will disable the
AdvanceTrac
with RSC system.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTrac
with
Roll Stability Controlevent is an indication that at least some of the
tires have exceeded their ability to grip the road; this may lead to an
increased risk of loss of vehicle control, vehicle rollover, personal injury
and death. If you experience a severe road event, SLOW DOWN.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
