Safety Canopy
system (if equipped)
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying Safety Canopy. Failure
to follow these instructions may
increase the risk of personal injury
in the event of a collision.
Do not lean your head on the door. The Safety Canopycould
injure you as it deploys from the headliner.
Do not attempt to service, repair, or modify the Safety Canopy
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a Safety Canopy. See your Ford or Lincoln
Mercury dealer.
All occupants of the vehicle including the driver should always
wear their safety belts even when an air bag SRS and Safety
Canopysystem is provided.
To reduce risk of injury, do not obstruct or place objects in the
deployment path of the inflatable Safety Canopy.
Seating and Safety Restraints
173

The Safety Canopyis mounted to roof side-rail sheet metal, behind the
headliner, above the first and second row seats. In certain lateral
collisions or rollover events, the Safety Canopysystem will be
activated, regardless of which seats are occupied. In certain rollover
events, the Safety Canopyon both sides of the vehicle will be inflated,
regardless of which seats are occupied. The Safety Canopyis designed
to inflate between the side window area and occupants to further
enhance protection provided in side impact collisions and rollover events.
The fact that the Safety Canopydid not activate in a collision does not
mean that something is wrong with the system. Rather, it means the
forces were not of the type sufficient to cause activation. The Safety
Canopyis designed to inflate in certain side impact collisions or
rollover events, not in rear impact, frontal or near-frontal collisions,
unless the collision causes sufficient lateral deceleration or rollover
likelihood.
Several Safety Canopy
system components get hot
after inflation. Do not touch them
after inflation.
If the Safety Canopy
system has deployed,the
Safety Canopywill not
function again unless replaced.
The Safety Canopysystem
(including the A, B and C
pillar trim) must be inspected
and serviced by a qualified
technician in accordance with
the vehicle service manual.If
the Safety Canopyis not
replaced, the unrepaired area will
increase the risk of injury in a
collision.

Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light as for front air bag system) will either
flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a collision
or rollover event.
Disposal of air bags and air bag equipped vehicles (including
pretensioners)
See your local dealership or qualified technician. Air bags MUST BE
disposed of by qualified personnel.
SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properly use safety
restraints for children. Also seeAir bag supplemental restraint system
(SRS)in this chapter for special instructions about using air bags.
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children (generally children who are four years old
or younger and who weigh 18 kg [40 lbs] or less) ride in your vehicle,
you must put them in safety seats made especially for children. Check
your local and state or provincial laws for specific requirements
regarding the safety of children in your vehicle. When possible, always
place children under age 12 in the rear seat of your vehicle. Accident
statistics suggest that children are safer when properly restrained in the
rear seating positions than in the front seating position.

5. Turn the key to 3 (ON) without
turning the key to 4 (START).
Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
Starting the engine
Note:Whenever you start your vehicle, release the key as soon as the
engine starts. Excessive cranking could damage the starter.
1. Turn the key to 4 (START)
without pressing the accelerator
pedal and release as soon as the
engine starts. The key will return to
3 (ON).
2. If the temperature is above–12°
C (10°F) and the engine does not
start within five seconds on the first
try, turn the key to OFF, wait 10
seconds and try again.

BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a“metal-to-metal,”“continuous grinding”or
“continuous squeal”sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
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 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.
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.
Driving

•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.
ABS warning lamp
ABS
TheABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned to the ON position. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake released. (If your brake warning lamp
illuminates, have your vehicle serviced immediately.)
Brake Assist
The Brake Assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and
maximizes the amount of brake booster assist, helping the driver to
achieve maximum braking pressure. Once a panic brake application is
detected, the system will remain activated as long as the brake pedal is
depressed. The system is deactivated by releasing the brake pedal.
When the system activates, the brake pedal will travel with very little
effort; this is normal.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
Driving

If the steering wanders or pulls, the condition could be caused by any of
the following:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components
Speed sensitive steering
Your vehicle is equipped with engine speed sensitive steering. At higher
engine speeds associated with high vehicle speed, the steering assist will
decrease to improve steering feel.
If the amount of effort required to steer your vehicle changes while
maintaining a constant engine speed, have the power steering system
checked by your dealer or a qualified service technician.
LIMITED-SLIP AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited slip axle functions like a standard rear axle.
Extended use of other than the manufacturer’s specified size tires on a
limited slip rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
To reduce the risk of injury, never run the engine with one wheel
off the ground, such as when changing a tire.
PREPARING TO DRIVE YOUR VEHICLE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a seat belt.

The AdvanceTracbutton allows
the driver to control the availability
of the AdvanceTracsystem.
AdvanceTracsystem status is
indicated by a warning indicator
light with a“sliding car”icon in the instrument cluster that will flash
when the system is active and an indicator light in the control button
that will illuminate when the system is turned off. In vehicles with a
message center, the message“ADVANCETRAC OFF”will be displayed.
If a failure is detected in the AdvanceTracsystem, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced immediately.
Pressing the control once will disable the AdvanceTracstability
enhancement and the engine power reduction portion of the traction
enhancement feature; the brake portion of the traction enhancement
feature will still function normally. Pressing and holding the control for
more than five seconds will disable the AdvanceTracstability
enhancementandtraction enhancement feature. If the vehicle is stuck
in snow or mud or when driving in deep sand, switching off the
AdvanceTracsystem may be beneficial so the wheels are allowed to
spin. If your vehicle seems to lose engine power while driving in deep
sand or very deep snow, switching off the AdvanceTracstability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTracperforms a system self-check. During AdvanceTrac
operation you may experience the following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTracindicator 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 AdvanceTracoperation.
