How does the Safety Canopysystem work?
The design and development of the
Safety Canopysystem included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy).
The Safety Canopysystem consists
of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one on each side of vehicle).
•A headliner designed to flex open
above the side doors to allow
Safety Canopydeployment.
•The same readiness airbag light, electronic control and diagnostic unit
as used for the front airbags.
•Two crash sensors mounted on the B pillar (one on each side of the
vehicle).
•Two crash sensors located at the C pillar behind the rear doors (one
on each side of the vehicle).
•Rollover sensor in the restraints control module (RCM).
The Safety Canopysystem, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats. The Safety Canopywill not interfere with
children restrained using a properly installed child or booster seat
because it is designed to inflate downward from the headliner above the
doors along the side window opening.
The Safety Canopysystem is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to

close an electrical circuit that initiates Safety Canopyinflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.
The Safety Canopyis mounted to roof side-rail sheet metal, behind the
headliner, along the entire side of the vehicle. In certain lateral collisions
or rollover events, the Safety Canopysystem will be activated,
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.
WARNING:If the Safety
Canopysystem has
deployed, the Safety Canopywill
not function again unless replaced.
The Safety Canopysystem
(including the A, B, C, and D
pillar trim and headliner) must be
inspected and serviced by an
authorized dealer. If the Safety
Canopyis not replaced, it will
not function again, which will
increase the risk of injury in a
future 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 theAirbag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
airbag is not required.
Any difficulty with the system is indicated by one or more of the
following:
•The readiness airbag light (same light as for front airbag system) will
either flash or stay lit.

that assists in starting the engine. After releasing the key from the 4
(start) position, the engine may continue cranking for up to 10 seconds
or until the vehicle starts.
Note:Cranking may be stopped at any time by turning the key to the off
position.
3. After idling for a few seconds, apply the brake, shift into gear and
drive.
Note:If the engine does not start on the first try, turn the key to the off
position, wait 10 seconds and try Step 2 again. If the engine still fails to
start, press the accelerator to the floor and try Step 2 again, keeping the
accelerator on the floor until the engine begins to accelerate above
cranking speeds; this will allow the engine to crank with the fuel shut off
in case the engine is flooded with fuel.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt a/c electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.

WINDOWS AND WIPER BLADES
The windshield, rear and side windows and the wiper blades should be
cleaned regularly. If the wipers do not wipe properly, substances on the
vehicle’s glass or the wiper blades may be the cause. These may include
hot wax treatments used by commercial car washes, water repellent
coatings, tree sap, or other organic contamination; these contaminants
may cause squeaking or chatter noise from the blades, and streaking and
smearing of the windshield. To clean these items, follow these tips:
•The windshield, rear windows and side windows may be cleaned with
a non-abrasive cleaner such as Motorcraft Ultra-Clear Spray Glass
Cleaner (ZC-23), available from your authorized dealer.
•The wiper blades can be cleaned with isopropyl (rubbing) alcohol or
Motorcraft Premium Windshield Washer Concentrate (ZC-32-A),
available from your authorized dealer. This washer fluid contains
special solution in addition to alcohol which helps to remove the hot
wax deposited on the wiper blade and windshield from automated car
wash facilities. Be sure to replace wiper blades when they appear
worn or do not function properly.
•Do not use abrasives, as they may cause scratches.
•Do not use fuel, kerosene, or paint thinner to clean any parts.
If you cannot remove those streaks after cleaning with the glass cleaner
or if the wipers chatter and move in a jerky motion, clean the outer
surface of the windshield and the wiper blades using a sponge or soft
cloth with a neutral detergent or mild-abrasive cleaning solution. After
cleaning, rinse the windshield and wiper blades with clean water. The
windshield is clean if beads do not form when you rinse the windshield
with water.
Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause
damage to the rear window defroster’s heated grid lines.
PANORAMIC ROOF DEFLECTOR (IF EQUIPPED)
Vacuum the wind deflector cloth to remove insects & loose dirt. Clean
with Motorcraft Professional Strength Carpet & Upholstery Cleaner
(ZC-54).
INSTRUMENT PANEL/INTERIOR TRIM AND CLUSTER LENS
Clean the instrument panel, interior trim areas and cluster lens with a
clean and damp white cotton cloth, then with a clean and dry white
