CELL PHONE USE
The use of Mobile Communications Equipment has become increasingly
important in the conduct of business and personal affairs. However,
drivers must not compromise their own or others’safety when using
such equipment. Mobile Communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in vehicle communications
systems, telematics devices and portable two-way radios.
A driver’s first responsibility is the safe operation of the vehicle.
The most important thing you can do to prevent a crash is to
avoid distractions and pay attention to the road. Wait until it is safe to
operate Mobile Communications Equipment.
CENTER CONSOLE (IF EQUIPPED)
Your vehicle may be equipped with a variety of console features. These
include:
•Utility compartment
•Power point (inside storage bin)
•Cupholders
•Air vents to the rear seating positions (heat only)
Use only soft cups in the cupholder. Hard objects can injure you
in a collision.
POSITIVE RETENTION FLOOR MAT
Position the driver floor mat so that
the eyelet is over the pointed end of
the retention post and rotate
forward to lock in. Make sure that
the mat does not interfere with the
operation of the accelerator or the
brake pedal. To remove the floor
mat, reverse the installation procedure.

button and remove the tongue from
the buckle.
Energy management feature
•This vehicle has a seat belt system with an energy management
feature at the front outboard seating positions to help further reduce
the risk of injury in the event of a head-on collision.
•This seat belt system has a retractor assembly that is designed to pay
out webbing in a controlled manner. This feature is designed to help
reduce the belt force acting on the occupant’s chest.
The front outboard and rear safety restraints in the vehicle are
combination lap and shoulder belts. The front outboard passenger and
rear seat safety belts have three types of locking modes described below:
Vehicle sensitive mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 8 km/h
(5 mph) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.
Webbing extraction sensitive mode
The webbing sensitive locking mode locks the webbing and prevents
more belt from being pulled out if the belt is pulled out too quickly. The
belt will unlock when you stop pulling on it.
Automatic locking mode
In this mode, the shoulder belt is pre-locked. The belt will still retract to
remove any slack in the shoulder belt.
The automatic locking mode is not available on the driver safety belt.

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.
Under normal operating conditions, brake dust may accumulate on the
wheels. Some brake dust is inevitable as brakes wear and does not
contribute to brake noise. The use of modern friction materials with
emphasis on improved performance and environmental considerations
can lead to more dust than in the past. Brake dust can be cleaned by
weekly washing with soapy water and a soft sponge. Heavier deposits can
be removed with Motorcraft Wheel and Tire Cleaner (ZC-37–A).
Anti-lock brake system (ABS)
This vehicle is equipped with an anti-lock braking system (ABS). 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. If the vehicle has continuous vibration or shudder
in the steering wheel while braking, the vehicle should be inspected by a
qualified service technician.
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. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
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 parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Your vehicle has an automatic parking brake release (except for
police/fleet vehicles which have the manual release). To release the
parking brake:
1. Start the vehicle.
2. Press the brake pedal.
3. Move the gearshift from the P (Park) position to one of the forward
gears (the parking brake will not release automatically when you shift
into reverse). The brake pedal must remain pressed while the gearshift is
moved.
If the parking brake fails to release
after completing this procedure, use
the manual parking brake release
lever.
Pull the lever to manually release
the parking brake.
TRACTION CONTROL(IF EQUIPPED)
Your vehicle may be equipped with the optional Traction Control
system. This system helps you maintain the stability and steerability of
your vehicle. It is especially useful on slippery and/or hilly road surfaces.
The system operates by detecting and controlling wheel spin. The system
borrows many of the electronic and mechanical elements already present
in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Controlportion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the rear brakes
in conjunction with engine torque reductions. Engine torque reduction is
realized via the fully electronic spark and fuel injection systems. This
process is very sensitive to driving conditions and very fast acting. The
rear wheels“search”for optimum traction several times a second and
adjustments are made accordingly.

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 Traction Control
event 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.
The Traction Controlsystem will allow your vehicle to make better use
of available traction on slippery surfaces while you are trying to
accelerate or while your foot is on the accelerator pedal. The system is a
driver aid which makes your vehicle easier to handle primarily on snow
and ice covered roads.
During Traction Controloperation you may hear an electric motor type
of sound coming from the engine compartment and the engine will not
“rev-up”when you push further on the accelerator. This is normal
system behavior.
If you should become stuck in snow
or ice or on a very slippery road
surface, try switching the Traction
Controlsystem off. This may allow
excess wheel spin to“dig”the
vehicle out and enable a successful
“rocking”maneuver.
The traction control indicator
flashes during a Traction Control
system event.
If the traction control indicator
comes on and stays lit, either:
•the Traction Controlsystem
requires service, or
•the customer has disabled the system using the traction control switch
located on the left side of the instrument panel.
The Traction Controlsystem will be on every time you turn the ignition
key from OFF to ON until you deactivate the system using the traction
control switch on the instrument panel left of the steering column.
STEERING
To prevent damage to the power steering system, never hold the steering
wheel at its furthest turning points (until it stops) for more than a few
seconds when the engine is running.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
